PART I.
ITEM 1. BUSINESS
Overview
We are an integrated discovery through late-stage clinical development biopharmaceutical company, with a focus on developing therapeutics that target the dysregulated transcription that causes cancer and other serious diseases. We have two investigational compounds in clinical trials, including one in a pivotal Phase 3 trial, and a third compound that we anticipate will enter the clinic in the first quarter of 2022. Our product engine, which includes our proprietary small molecule microarray screening platform, provides us with the capability to map and target transcription regulatory networks (TRNs) in a differentiated manner to enable discovery of novel compounds and improve our translational capabilities.
Our lead product candidate, entospletinib, is an orally administered, selective spleen tyrosine kinase (SYK) inhibitor that has been previously tested in more than 1,300 people, including more than 200 patients with acute myeloid leukemia (AML). Based on clinical results in a biomarker-defined subset of patients and following discussions as part of an End-of-Phase 2 meeting with the FDA, we have initiated our randomized, double-blinded, placebo-controlled registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in approximately 180 patients with newly diagnosed NPM1-mutated AML. We are also developing lanraplenib, our next-generation orally-administered SYK inhibitor, and plan to initiate a Phase 1b/2 clinical trial in the first quarter of 2022. This clinical trial will evaluate lanraplenib in combination with gilteritinib in patients with relapsed or refractory FLT3-mutated AML. In addition, we are developing KB-0742, our internally discovered, oral cyclin dependent kinase 9 (CDK9) inhibitor, for the treatment of MYC-amplified and other transcriptionally addicted solid tumors. The first patient in our Phase 1/2 clinical trial was dosed in February 2021, and we reported initial data in the fourth quarter of 2021.
In our research efforts, we are leveraging our product engine to drive multiple oncology discovery programs targeting dysregulated transcription factors and their associated TRNs. Some of the most powerful oncogenes in all of human cancer encode transcription factors: proteins that bind to specific DNA sequences on the genome and control how sets of genes are turned on and off. Transcription factors historically have been difficult to target in drug development because they are typically intrinsically disordered, adopting a functional structure only when assembled with a complex of cofactors in the nucleus on the genome. Transcription factors with aberrant expression or activity result in dysregulated TRNs, which are frequently responsible for reprogramming healthy cells into cancerous tumor cells. Therapeutically modulating dysregulated transcription factors requires a sophisticated and holistic approach due to their complexity and their regulation of complex TRNs in a context-dependent manner. Based on this work, in November 2021, we announced the advancement of two programs, one focused on the MYC TRN and one focused on the androgen receptor (AR) TRN.
We take a systems biology approach to unlocking therapeutic mechanisms within dysregulated TRNs using our differentiated product engine. Our product engine includes three interconnected components, each of which is informed by our translational expertise, and which we believe enables efficient discovery and development of new product candidates:
•Map TRNs – Leverage our computational biology expertise, engineered cell systems and high throughput transcriptomic profiling to map the structure of TRNs defined by specific dysregulated transcription factors and identify the gene expression signature of selective TRN modulation that can be carried forward into discovery and clinical translation.
•Define Dependencies – Apply causal and mechanistic insights to analyze TRNs and to identify critical nodes that may represent tractable targets for drug discovery. We do this by identifying which genetic sequences transcription factors bind to, which proteins they interact with, and which genes they regulate in specific cellular contexts.
•Identify Modulators – Conduct high throughput screens using our proprietary small molecule microarray (SMM) screening platform against dysregulated transcription factors in tumor cell lysates to identify selective TRN modulators and determine mechanism of action. Such modulators are then further optimized to refine their pharmacological properties.

Entospletinib and Lanraplenib
Our lead product candidate, entospletinib, is a selective inhibitor of SYK, a critical node in a dysregulated TRN within AML defined by persistent high expression of the transcription factors HOXA9 and MEIS1 (HOX/MEIS). Through analysis of AML patient sample datasets compiled by various academic collaborator groups, we selected NPM1 mutation as a robust genomic biomarker of HOX/MEIS elevation in AML. NPM1 mutation is reported to be present in approximately one-third of adult AML patients. We believe that utilizing an NPM1 mutation test, both for patient selection and assessment of measurable residual disease (MRD) negative complete response (CR) as a registrational endpoint enables a highly efficient regulatory path for seeking potential accelerated approval. We held an End-of-Phase 2 meeting with the FDA to discuss our proposed design, endpoints and companion diagnostic strategy for our planned entospletinib registrational trial in patients with NPM1-mutated AML. Based upon the discussion and guidance from the meeting with FDA, we initiated our registrational Phase 3 AGILITY clinical trial of entospletinib using MRD-negative CR as the primary endpoint. We announced the dosing of the first patient in that study in December 2021. The trial is designed to evaluate entospletinib in combination with standard of care anthracycline and cytarabine (7+3) chemotherapy in patients newly diagnosed with NPM1-mutated AML who are fit for intensive induction.
We are also developing a next-generation SYK inhibitor, lanraplenib, and anticipate beginning a Phase 1b/2 trial in the first quarter of 2022. Lanraplenib has improved pharmacokinetic (PK) and pharmacologic properties compared with entospletinib. We believe that lanraplenib’s differentiated pharmacologic properties support its evaluation as a component of more extended combination dosing regimens with gilteritinib, which is dosed to progression. This lanraplenib clinical trial will include a dose-escalation and an expansion cohort study design. In this trial, the Phase 1b stage will evaluate initial safety, PK and anti-leukemic activity of escalating once-daily doses of lanraplenib in combination with the standard approved dose of gilteritinib in relapsed or refractory FLT3-mutated AML patients. Once a recommended dose is established and pending the data from the Phase 1 stage, we plan to initiate the Phase 2 stage of the trial, with an expansion cohort of approximately 30 patients to further evaluate the safety of lanraplenib and assess its anti-leukemic activity as measured by composite CR rate and duration of response. Based on the data from the first stage of the study, we anticipate deciding whether to proceed with the second stage by mid-2023. Assuming we are successful with the Phase 1b/2 program, we anticipate deciding whether to proceed to Phase 3 in mid-2024. We anticipate making public announcements related to both decisions.
KB-0742
KB-0742, generated from our product engine’s SMM platform is a highly selective, oral CDK9 inhibitor being developed to treat MYC-amplified solid tumors and other trascriptionally addicted tumors. The FDA cleared our IND submission of KB-0742 in December 2020. In February 2021, we initiated our Phase 1/2 clinical trial of KB-0742 to evaluate its safety, PK and PD. Following the dose escalation stage of the clinical trial, we plan to enroll the expansion cohorts at the recommended Phase 2 clinical trial dose and schedule in patients with MYC-amplified solid tumors and other transcriptionally addicted cancers. We reported initial data from the dose escalation stage of the clinical trial in the fourth quarter of 2021 and expect to report the recommended Phase 2 dose and data from the Phase 1 portion of this trial in the fourth quarter of 2022.

Our Pipeline
We have developed a robust clinical pipeline through a combination of internal discovery efforts and focused asset acquisition. The following chart summarizes the current stages of our development programs, including our lead product candidate, entospletinib, as well as lanraplenib KB-0742, and our next anticipated milestones.
8
We also are executing on robust discovery programs across multiple TRNs, which focus on four cancer types where dysregulated transcription plays a central role: hematologic malignancies, prostate cancer, MYC-driven cancers, and small cell/neuroendocrine cancers. We anticipate submitting an IND for a drug candidate arising from one of these programs in 2023, although we may not be successful in identifying product candidates that can selectively modulate the specific oncogenic TRNs associated with these malignancies.
Entospletinib and Lanraplenib: our SYK Inhibitor Portfolio
Our lead product candidate, entospletinib, is a selective inhibitor targeting SYK, a critical node in a dysregulated TRN within AML defined by persistent high expression of the transcription factors HOX/MEIS. SYK is a non-receptor tyrosine kinase and is an important mediator of immunoreceptor signaling in hematopoietic cells with a clearly established role in both malignant and non-malignant hematologic disease.
SYK is a critical dependency in biomarker-defined subsets of AML patients characterized by persistent high HOX/MEIS expression. Multiple AML driver mutations, including NPM1, MLL (KMT2A) gene rearrangements (MLL-r) and DNMT3A, have been associated with elevation of HOX/MEIS, which increases quantity and activity of SYK as part of an oncogenic TRN. SYK contributes to the leukemia cell state through multiple mechanisms, including direct modulation of downstream growth-promoting transcriptional programs, phosphorylation of FLT3, a known driver of leukemogenic signaling, and participation in a positive feedback loop to MEIS1 that maintains high MEIS1 expression. We believe these multiple oncogenic functions make SYK a compelling therapeutic target and a critical node in the HOX/MEIS TRN.
Our expertise in TRN biology allowed us to recognize SYK as a critical node in the HOX/MEIS TRN, and in July 2020, we acquired a portfolio of selective, orally bioavailable small molecule SYK inhibitors from Gilead. The acquisition included two clinical-stage product candidates:
•Entospletinib – An orally administered SYK inhibitor with high selectivity, dosed twice-daily (BID). Entospletinib has been evaluated in multiple clinical trials in hematologic malignancies, including a three-arm Phase 1b/2 clinical trial in 148 AML patients, both as a monotherapy and in combination with standard of care. In one arm of this study, 53 newly diagnosed AML patients were treated with entospletinib combined with intensive chemotherapy. The trial endpoints of establishing a safe combination dose of entospletinib with intensive chemotherapy and of estimating the rate of CR to this combination were met for this study arm. In addition, a retrospective analysis revealed higher CR rates in subjects with MLL-r and NPM1 mutations than in subjects with neither mutation. Superior overall survival was also observed in patients with high HOX/MEIS mRNA expression as compared to patients with low expression. The results of this retrospective analysis are consistent with the preclinical hypothesis of SYK dependency in HOX/MEIS-driven AML. In the first quarter of 2021, we had an End-of-Phase 2 meeting with the FDA to discuss our proposed design, endpoints and companion diagnostic strategy for our
9
planned entospletinib registrational trial in patients with NPM1 mutated AML. Based on the discussion and guidance from the meeting, in December 2021 we initiated our registrational Phase 3 AGILITY clinical trial of entospletinib using MRD-negative CR as the primary endpoint in support of potential accelerated approval. We expect to report MRD-negative CR data from this trial in the second half of 2023. In 2021, we initiated similar discussions regarding use of this surrogate primary endpoint with the European Medicines Agency, and received corresponding scientific advice. Based on the scientific advice, we are continuing to pursue this pathway to potential approval in the EU.
•Lanraplenib – A next generation SYK inhibitor with improved PK and pharmacologic properties compared with entospletinib, including once daily (QD) dosing, no food restrictions and compatibility with proton pump inhibitors. Lanraplenib was previously studied in clinical trials that included more than 250 healthy volunteers and patients with autoimmune diseases, establishing an acceptable safety profile. Our preclinical evaluation of lanraplenib has show equivalent anti-leukemic activity in head-to-head comparisons with entospletinib. In July 2021, the FDA cleared our IND submission to begin investigating lanraplenib as a treatment for leukemia. This trial will be the first to assess the compound in patients with cancer. The Phase 1b/2 trial will evaluate lanraplenib in combination with gilteritinib in patients with FLT-3 mutated AML. We expect to initiate the study in the first quarter of 2022.
KB-0742: our CDK9 Inhibitor
KB-0742 was generated from our product engine’s SMM screening platform. KB-0742 is an oral CDK9 inhibitor with a differentiated biochemical selectivity and clinical PK profile. CDK9 is a serine/threonine kinase that forms the catalytic core of the positive transcription elongation factor b (P-TEFb). CDK9 is a global regulator of transcription, and has been recognized as a high-value oncology drug target due to its essential role in maintaining high levels of transcription for oncogenes and short-lived anti-apoptotic proteins.
In February 2021, the first patient was dosed in the first stage of our Phase 1/2 clinical trial to evaluate KB-0742’s safety, PK and PD properties across multiple dose levels. In November 2021, we reported initial results from the first three dose levels of our ongoing dose escalation stage of our Phase 1/2 trial of KB-0742 in patients with solid tumors. The PK analysis showed oral bioavailability and dose-proportional exposure across the first three dose levels, with low to moderate variability between patients. Among the 12 patients treated in the trial, KB-0742 had a terminal half-life of 24 hours, with approximately 2 to 2.5-fold accumulation between Day 1 and Day 10. This long plasma half-life supports our efforts to define a therapeutic window for CDK9 inhibition. Proprietary target engagement assays developed and prospectively validated by us demonstrated dose-dependent reduction of phosphorylation of Ser2 on RNA Polymerase II (pSer2), a direct substrate target of CDK9, as well as reduced expression of CDK9-dependent genes in peripheral blood mononuclear cells from patients at each of the three dose levels. We believe that consistent with the results we observed in our preclinical modeling of KB-0742, further dose escalation is required to reach desired levels of CDK9 inhibition. The nature and severity of the adverse events observed is consistent with what is typically seen among heavily pretreated patients with advanced cancer in Phase 1 trials. We are continuing to enroll and dose escalate patients in this trial.
Our initial development focus for KB-0742 is for potential use in advanced solid tumors with MYC genomic copy number gain (amplification) transcriptionally addicted cancers. MYC is a well-characterized transcription factor and a long-recognized driver of cancer that is dysregulated in a significant proportion of malignancies, including lung, breast, ovarian, and various gastro-intestinal cancers, often as a result of genomic amplification. CDK9 is a critical node in the MYC TRN, acting both as an upstream driver of MYC expression and a downstream co-factor of MYC itself that is required to drive the MYC-dependent oncogenic gene expression program. Preclinical characterization of KB-0742 has demonstrated that MYC genomic amplification is associated with increased tumor sensitivity across multiple histologies, potentially enabling a tissue of origin-agnostic development strategy.
After identifying the recommended Phase 2 dose and dosing schedule, we intend to enroll expansion cohorts of patients with MYC-amplified solid tumors and other transcriptionally addicted tumor types. The subsequent development path to registration will be based on the frequency, magnitude and durability of responses observed in these expansion cohorts.
Discovery Programs
10
We continually invest in early discovery efforts utilizing our proprietary product engine, with the goal of expanding our pipeline of future product candidates. Our current efforts are focused on four cancer types where dysregulated transcription plays a central role: hematologic malignancies, prostate cancer, MYC-driven cancers, and small cell/neuroendocrine cancers (SCNC). We are developing a deep understanding of the underlying disease biology within these cancer types, engineering robust systems to characterize transcription factor perturbation signatures, and are evaluating multiple potential opportunities for therapeutic intervention through modulation of key TRN components. We select our discovery targets based on scientific, translational and competitive considerations, prioritizing those where dependency has been demonstrated in a defined patient population with high unmet medical need, and where we believe we can design an efficient early clinical translation strategy based upon our understanding of the disease biology.
Our Strategy
Our goal is to become a leading biopharmaceutical company by discovering transformational small molecule modulators of historically challenging targets in cancer and other serious diseases, and then developing and ultimately commercializing those agents using a precision medicine approach for patient populations with high unmet medical need. We intend to do this by continuing to employ our proprietary product engine to discover and develop product candidates. The key elements of our strategy include:
•Rapidly advance our SYK program into and complete registrational clinical trials. We believe that the early clinical data generated in clinical trials of entospletinib, combined with the viability of NPM1 mutations as a genomic marker both for HOX/MEIS-high patient selection and measurement of MRD-negative CR as a primary endpoint, enables an expeditious path to potential accelerated regulatory approval in newly diagnosed AML patients with NPM1 mutations who are eligible for intensive chemotherapy. Based upon the discussion and guidance from our End-of-Phase 2 meeting with FDA, in December 2021 we initiated our registrational Phase 3 AGILITY clinical trial of entospletinib using MRD-negative CR as the primary endpoint. In 2021, we initiated similar discussions regarding use of this surrogate primary endpoint with the European Medicines Agency, and received corresponding scientific advice. Based on the scientific advice, we are continuing to pursue this pathway to potential approval in the EU.We expect to report MRD-negative CR data from our AGILITY trial in the second half of 2023.
•Establish clinical proof of concept for our CDK9 program. In February 2021, the first patient was dosed in the first stage of our Phase 1/2 clinical trial, designed to initially assess the safety, PK and PD profile of KB-0742 in patients with advanced solid tumors, and define an optimal dose and schedule for subsequent signal-seeking expansion cohorts in cancer patients with MYC-amplified solid tumors and other transcriptionally addicted cancers. We reported initial data from the dose escalation stage of the clinical trial in the fourth quarter of 2021, and expect to report the recommended Phase 2 dose and data from the Phase 1 portion of this trial in the fourth quarter of 2022.
•Continue to grow our pipeline of product candidates. We plan to establish a robust pipeline of additional highly differentiated product candidates targeting dysregulated transcription factors and their associated TRNs, particularly through continued investment in our SMM platform, and in our chemical biology, and computational and experimental biology capabilities.
•Selectively enter into strategic collaborations to maximize the potential of and to expand our pipeline. Our product engine has the potential to identify differentiated product candidates addressing a wide variety of diseases with high unmet medical need. We believe this provides us the opportunity to selectively evaluate and, if appropriate, enter into strategic collaborations that leverage our potential future partners’ complementary capabilities to advance and accelerate our development programs or expand our internal discovery efforts, as well as maximize our commercial reach. We also believe we have built a team well suited for the continued identification, evaluation and acquisition of additional product candidates or technologies that complement our core efforts and capabilities.
•Leverage our experienced management team to build a fully-integrated, science-driven biopharmaceutical company addressing high unmet medical needs. Our management team possesses significant expertise across all stages of discovery, translation, late-stage clinical development and commercialization. Collectively, our management team has a track record of obtaining regulatory approval and has successfully commercialized over 25 therapeutic products, including several that have
11
fundamentally transformed patient outcomes. We plan to progress our product candidates expeditiously through regulatory approval, with the vision of ultimately building a fully-integrated, science-driven biopharmaceutical company.
SYK Inhibitor Product Candidates
Entospletinib and lanraplenib are selective inhibitors of SYK, an important mediator of immunoreceptor signaling in hematopoietic cells with a clearly established role in both malignant and non-malignant hematologic disease.
Entospletinib
Entospletinib has been investigated in multiple clinical trials in patients with hematologic malignancies and has shown encouraging activity in patients with AML who have high expression of HOX/MEIS. Multiple preclinical studies have established a clear dependency between SYK activity and the HOX/MEIS leukemogenic TRN.
We had an End-of-Phase 2 meeting with the FDA in early 2021 to discuss our proposed design, endpoints and companion diagnostic strategy for our entospletinib registrational trial in patients with NPM1 mutated AML. Based upon the discussion and guidance from the meeting with FDA, we initiated our registrational Phase 3 AGILITY clinical trial of entospletinib using measurable residual disease (MRD) negative complete response (CR) as the primary endpoint to support a potential accelerated approval. We initiated the study in December 2021. We expect to report MRD-negative CR data in the second half of 2023. In 2021, we initiated similar discussions regarding use of this surrogate primary endpoint with the European Medicines Agency, and received corresponding scientific advice. Based on the scientific advice, we are continuing to pursue this pathway to potential approval in the EU.
Prior Development of Entospletinib
Since it entered clinical testing in 2013, more than 1,300 people have received entospletinib, including healthy volunteers, patients with renal impairment and inflammatory conditions, and more than 700 patients with hematologic malignancies.
The first clinical trial in healthy volunteers and patients with rheumatoid arthritis (RA) revealed PK consistent with BID dosing and dose dependent SYK inhibition at doses up to 600 mg. Entospletinib was generally well tolerated in healthy volunteers with the most frequently reported adverse events (AEs) being headache, nausea and constipation without any clear relationship to dose level. Mildly increased liver enzymes were observed in some healthy subjects and patients with RA.

The largest group of patients in which entospletinib has been tested have been patients with hematologic malignancies. More than 700 patients, predominantly with B cell malignancies, such as chronic lymphocytic leukemia (CLL), have been treated with entospletinib. Results in CLL were encouraging and consistent with response rates seen for other small molecule inhibitors of B cell receptor signaling such as PI3K delta or Bruton’s Tyrosine Kinase (BTK) inhibitors. An overall response rate (ORR) of 61% and median Progression Free Survival (mPFS) of 13.8 months was observed in 41 patients with relapsed or refractory CLL previously treated with anti-CD20 antibody and alkylating agents. Among 49 patients with CLL that had progressed after treatment with PI3K delta or BTK inhibitors, the ORR was 33% with a mPFS of 5.6 months. The most frequently reported treatment-related AEs, with an incidence greater than 10% in CLL patients, were fatigue, nausea, diarrhea, headache, decreased appetite and fever. AEs attributed to entospletinib of Grade 3 (severe or medically significant but not life-threatening) or greater in at least 5% of patients included neutropenia (four subjects), elevated liver enzymes, hyperbilirubinemia, anemia and hypophosphatemia (two subjects each). Fourteen subjects reported serious AEs, including pneumonia (three subjects), angina pectoris, febrile neutropenia, hypokalemia and sepsis (two subjects each) and acute myocardial infarction, atrial fibrillation, cardiac congestive failure, cellulitis, chest pain, clavicle fracture, dehydration, dyspnea, encephalopathy, epiglottitis, fall, hepatic function abnormal, hepatotoxicity, hypocalcemia, hyponatremia, ischemic cardiomyopathy, leukocytosis, muscular weakness, musculoskeletal chest pain, non-cardiac chest pain, pericardial effusion, pericarditis, pyrexia and rotavirus infection (one subject each), all of which were listed in the applicable investigator brochure describing safety results, without mention of study drug relatedness. Five subjects reported serious AEs assessed by the investigator as related to entospletinib, which included: dyspnea, epiglottitis, febrile neutropenia, hepatic function abnormal, hepatotoxicity and pneumonia. Overall, entospletinib was well-tolerated by CLL patients in these clinical trials. We believe this observed anti-leukemic activity may warrant further investigation in CLL in combination with other agents.
Entospletinib has also been tested in a Phase 1b/2 clinical trial in 148 patients with AML. Early safety studies were conducted in relapsed patients as monotherapy and in combination with intensive chemotherapy and in newly diagnosed elderly patients in combination with HMAs such as azacytidine or decitabine. Aside from the AEs typical of the disease and intensive chemotherapy, such as cytopenias and fever, the main AEs attributable to entospletinib included diarrhea, nausea, and febrile neutropenia. These clinical trials revealed encouraging activity in a subset of patients with AML who have high HOX/MEIS expression, described in greater detail below.
Therapeutic Rationale and Clinical Data in HOX/MEIS-High AML
AML is one of the most common forms of acute leukemia in adults. Despite multiple recent drug approvals, the disease still bears a poor prognosis with less than 30% of patients surviving five years from diagnosis. Although the median age at diagnosis is 67, only younger, typically less than 65 years old, and fitter patients are eligible for intensive chemotherapy, involving seven days treatment with cytarabine and three days treatment with an anthracycline drug such as daunorubicin or idarubicin. Approximately 60% to 70% of these patients achieve CR, but most will experience disease relapse in less than 18 months. Among patients who achieve CR but remain positive for MRD, remissions are often particularly short-lived. For older and less fit patients, prognosis is even worse. Therapeutic options for these patients have historically been limited to palliative treatment with HMAs with CR rates of approximately 30% followed by relapse within a matter of months in a majority of responding patients. The recent approval of the BCL-2 inhibitor venetoclax in combination with HMAs has improved the response rates in older AML patients but relapse free survival remains unacceptably short. There is a clear need for additional therapies to drive improved outcomes in AML, especially agents that improve the MRD-negative CR rate and durability of response in a frontline setting.
SYK activates several aberrant signaling pathways in AML to promote leukemic cell survival and proliferation. SYK is a particularly critical dependency in HOX/MEIS high AML. HOX/MEIS is overexpressed in a significant subset of AML patients. HOXA9 and MEIS1 are transcription factors that work together to drive a gene expression program in primitive myeloid cells. As these cells normally mature, expression of these transcription factors is down-regulated.
13
Multiple AML driver mutations including NPM1, MLL-r and DNMT3A mutations have been associated with a failure to down-regulate HOX/MEIS as shown in the figure below. This figure is based on our internal analysis of genomic and transcriptomic data from over 400 AML patient samples obtained through the Leukemia and Lymphoma Society’s “Beat AML” program. The figure below depicts mRNA levels for either the HOXA9 or MEIS1 genes across the common AML driver mutations NPM1 (left), MLL-r (center), and DNMT3A (right). For each AML driver mutation, HOXA9 and MEIS1 mRNA levels are shown for either patients that are wildtype for that mutation (grey boxes) or mutated (blue boxes). For each cohort (wild type or mutant), outliers are defined as those patients with mRNA levels exceeding 1.5x the interquartile range (IQR). In all cases, AML driver mutations are associated with increased mRNA levels of HOXA9 and MEIS1 that are consistent with a failure to down-regulate HOX/MEIS expression and are considered statistically significant by a two-sided Mann-Whitney-Wilcoxon test. Failure to down-regulate HOX/MEIS expression locks in the abnormal undifferentiated transcriptional program that defines AML.
AML Driver Mutations and mRNA Expression Levels of HOXA9/MEIS1
Recent publications show that elevated HOX/MEIS results in increased quantity and activity of SYK as part of an oncogenic TRN. SYK contributes to the leukemia cell state by modulating downstream transcriptional programs including genes that promote cytokine independent growth. In addition, SYK promotes leukemia indirectly through phosphorylation of FLT3, a known driver of leukemogenic signaling. Finally, SYK contributes to the stability of the HOX/MEIS TRN through a positive feedback loop to MEIS1 that maintains MEIS1 elevation.
14
SYK and HOX/MEIS Oncogenic Feedback Loop
15
Independent of these publications, the Beat AML program tested genomically characterized bone marrow specimens from 572 AML patients in vitro for sensitivity to 122 small molecule drugs or compounds including entospletinib. Our internal analysis of the raw data from this screening program is shown in the figure below, which plots the average difference in area under curve (AUC) drug response between mutant and wild-type on the x-axis and the false discovery rate (FDR) corrected Q value (determined using a two-sided Student’s t-test from a linear model fit) on the y-axis. Sensitivity to entospletinib correlated, with high statistical significance, with the presence of NPM1 mutations alone (FDR < 0.001) or in combination with FLT3 (FDR < 0.0001) or DNMT3A mutations (FDR < 0.01). We believe these multiple oncogenic functions make SYK a compelling therapeutic target and a critical node in the HOX/MEIS TRN.
From July 2015 to February 2019, Gilead investigated the use of entospletinib in a Phase 1b/2 clinical trial enrolling 148 AML patients in the United States, Canada and Germany. Patients were enrolled into one of three arms:
•Arm A: previously untreated, fit AML patients treated with entospletinib monotherapy followed by combination with intensive chemotherapy;
•Arm B: previously untreated elderly or unfit patients treated with entospletinib monotherapy followed by combination therapy with entospletinib and HMA; and
•Arm C: relapsed or refractory AML patients or patients with MLL-r treated with entospletinib monotherapy only.
Dose limiting toxicity was not encountered during monotherapy or combination dose escalation but a dose of 400 mg BID was selected for further expansion in Phase 2 clinical trials based on data suggesting no significant additional target engagement above this dose. Drug-related AEs were primarily febrile neutropenia, maculopapular rash and gastrointestinal, such as nausea, diarrhea, and constipation.
16
A total of 53 patients were enrolled in Arm A. Of 10 MLL-r patients enrolled, one achieved a CR during the 14-day entospletinib monotherapy window and nine were in CR at the end of combination induction. Across all 53 patients, the CR rate at the end of combination entospletinib and intensive chemotherapy induction was 70%, which is in line with historical CR rates for intensive chemotherapy. A retrospective biomarker analysis of Arm A explored the hypothesis that patients with high HOX/MEIS mRNA are more likely to benefit from the addition of entospletinib to intensive chemotherapy. This retrospective analysis revealed that CR rates in the genetic subsets associated with high HOX/MEIS expression, NPM1 mutations and MLL-r, were 87% (13 out of 15) and 90% (9 out of 10) respectively, compared to 54% (15 out of 28) in patients with neither mutation. Historical CR rates of 56% to 68% with intensive chemotherapy alone have been reported for MLL-r patients. For patients with NPM1 mutations, historical CR rates with intensive chemotherapy alone have ranged from 66% to 87% depending on age and cytogenetics. Age greater than 60 and adverse cytogenetics are associated with the lower end of this range. The subjects enrolled in this study had a median age of 60, and six of the 15 NPM1 mutated patients had secondary AML associated with adverse cytogenetics. The difference between the combined CR rates for the NPM1 and MLL-r groups and the NPM1/MLL wild type groups is statistically significant with a p value of 0.004 (Z-test). HOX/MEIS gene expression was evaluated for 34 patients in whom baseline samples were available for analysis. This analysis revealed that entospletinib-treated patients with high HOX/MEIS mRNA levels (determined as those above the median level of expression) experienced superior overall survival (OS) with a hazard ratio of 0.32 (95% confidence interval 0.1 – 0.997, P = 0.038, log rank test) when compared to those with low HOX/MEIS mRNA levels (determined as those below the median level of expression).
Entospletinib Phase 2 Clinical Trial Data Showed Activity in Defined AML Subsets
The 51 patients enrolled in Arm B had an overall CR rate of 26% with the combination of entospletinib and HMA, which is in line with the historical CR rate for HMA alone. Only two subjects with MLL-r were enrolled in this Arm and exploratory biomarker analyses were not conducted.
Arm C examined entospletinib monotherapy in 13 subjects with relapsed or refractory (R/R) AML with MLL-r, six subjects with R/R AML with wild type MLL and nine newly diagnosed subjects with AML who refused intensive chemotherapy or HMA. Two out of 13 R/R MLL-r subjects in Arm C achieved CRs with entospletinib monotherapy, consistent with the biological hypothesis.
We believe that the retrospective analyses of these clinical data from subjects in the genetic subsets associated with high HOX/MEIS expression, along with the demonstrated biological rationale and our analysis of the Beat AML entospletinib sensitivity data, strongly support the dependency between SYK and HOX/MEIS and provide encouraging evidence of the potential for SYK inhibition to significantly improve upon standard of care for AML patients with elevated HOX/MEIS.
17
Entospletinib for Patients with AML with NPM1 Mutations
We are developing our lead SYK inhibitor, entospletinib, in combination with intensive chemotherapy in newly diagnosed patients with AML who have NPM1 mutations. While we do not have randomized data showing that the CR rates for newly-diagnosed AML patients with NPM1 mutations treated with entospletinib and intensive chemotherapy are superior to those that would be seen if treating this population with intensive chemotherapy alone, the results from the Gilead-sponsored Phase 1b/2 study suggest that patients with high HOX/MEIS expression respond better to the combination of entospletinib and chemotherapy than patients without this feature. NPM1 mutation is an attractive biomarker for patient selection due to its predictive value of high HOX/MEIS, utility in patient screening and suitability for assessment of MRD.
Predictive Value. Although MLL-r and DNMT3A mutations have higher than average HOX/MEIS expression, NPM1 mutations are the most consistent genetic driver and predictive marker of high HOX/MEIS, as discussed above. Prior to joining our company, our Senior Vice President of Biology was part of the academic team that revealed the mechanistic basis for this association. Based on these considerations, we believe that focusing initially on a more homogeneous group of AML patients defined by a single mutation, NPM1, provides the highest probability of success.
Screening Efficiency. NPM1 mutations are common in AML, reportedly presenting in approximately one-third of adult AML patients. Further, NPM1 mutation status is already routinely assessed in AML patients as part of standard diagnostic workup in the clinic, which we believe will help facilitate clinical trial enrollment and streamline the process for developing and validating a companion diagnostic.
MRD Assessment. Because NPM1 mutation is a genomic marker that can be detected with very high sensitivity using digital Polymerase Chain Reaction or next generation sequencing approaches, we believe NPM1 mutation is an ideal biomarker for MRD assessment. Regulatory approvals on the basis of MRD status have been granted in acute lymphocytic leukemia and CLL, and a growing body of evidence has demonstrated that MRD status post-treatment is a strong predictor of overall survival in AML. We believe that the early clinical data generated by entospletinib, combined with the viability of NPM1 mutation as a genomic marker both for HOX/MEIS-high patient selection and measurement of MRD-negative CR as a surrogate primary endpoint, may enable accelerated regulatory approval of entospletinib in newly diagnosed AML patients with NPM1 mutations.
We had an End-of-Phase 2 meeting with the FDA in early 2021, and we are engaging in similar discussions with European regulatory authorities, to discuss our proposed design, endpoints and companion diagnostic strategy for our planned entospletinib registrational trial in patients with NPM1 mutated AML. Based on discussions with FDA, we initiated our randomized, double-blinded, placebo-controlled registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in approximately 180 newly diagnosed NPM1-mutated AML patients in December 2021. NPM1 mutation status for enrollment in the trial will be assessed at a central laboratory using a PCR-based assay. We are working with our third-party diagnostic partner to complete the validation of the assay necessary to meet regulatory requirements for a companion diagnostic in parallel with the conduct of the clinical trial. Patients are randomized to receive standard of care intensive chemotherapy in combination with twice-daily entospletinib or a placebo. MRD is assessed in patients who achieve a CR after two cycles of chemotherapy. These patients then go on to receive consolidation therapy with cytarabine and entospletinib or placebo as per their randomization assignment. MRD-negative CR in the intent-to-treat population is the proposed primary endpoint for accelerated approval. Patients will remain in the clinical trial in order to capture event-free and overall survival clinical data.
Our Next Generation SYK Inhibitor Product Candidate: Lanraplenib
Lanraplenib is a SYK inhibitor previously developed by Gilead for autoimmune indications, and has been evaluated in multiple Phase 2 clinical trials in more than 250 patients including health volunteers and patients with autoimmune disease. Lanraplenib has exhibited improved PK properties compared with entospletinib, including an improved half-life, which is compatible with QD dosing among other benefits.
Preclinical modeling suggests that dose levels selected for Phase 2 clinical trials of lanraplenib in autoimmune disease resulted in lower SYK target engagement compared to the dose of entospletinib used in hematologic malignancies. We believe that a higher dose of lanraplenib resulting in equivalent SYK target engagement achieved with entospletinib may create an opportunity to develop lanraplenib in oncology and other indications. Based on our detailed preclinical evaluation of lanraplenib, which showed equivalent anti-leukemic activity in
18
head-to-head comparisons with entospletinib in various AML models, we are moving forward with a Phase 1b/2 trial, which we anticipate will begin in the first quarter of 2022. and which will evaluate lanraplenib in combination with gilteritinib in patients with relapsed or refractory FLT3-mutated AML.
KB-0742: Our Investigational CDK9 Inhibitor
KB-0742 is an oral CDK9 inhibitor with a differentiated selectivity profile. CDK9 is a global regulator of transcription and a critical node in the oncogenic TRN resulting from MYC overexpression. While CDK9 is a required component of transcriptional machinery for many genes across the genome, certain tumors are “transcriptionally addicted,” meaning that they require a higher level of transcription than normal cells in order to survive.
KB-0742 was internally optimized from an SMM hit and we believe it possesses differentiated selectivity for CDK9 among other attractive pharmacologic properties. While several other compounds targeting CDK9 are being clinically investigated for the treatment of cancer, their published biochemical selectivity profiles indicate the potential for cross-reactivity to cell cycle CDKs at clinical exposures. We believe this may contribute to the toxicity and limited therapeutic index observed with these agents and explain why in general they have not advanced to later-stage clinical trials.
The FDA cleared our IND submission of KB-0742 in December 2020. In February 2021, we initiated our Phase 1/2 clinical trial of KB-0742 to evaluate its safety, PK and PD. Following the dose escalation stage of the clinical trial, we plan to enroll the expansion cohorts at the recommended Phase 2 clinical trial dose and schedule in patients with MYC-amplified solid tumors and pother transcriptionally addicted cancers. We reported initial data from the dose escalation stage of the clinical trial in the fourth quarter of 2021 and expect to report the recommended Phase 2 dose and data from the Phase 1 portion of this trial in the fourth quarter of 2022.
Therapeutic Rationale in MYC-amplified tumors
MYC family transcription factors (MYC, MYCN and MYCL) are master regulators of cell growth, proliferation, differentiation and metabolism, and are among the most frequently dysregulated targets in malignancies. While MYC can be up-regulated through various mechanisms and participates in many oncogenic TRNs, we believe that MYC amplification is one of the clearest markers of transcriptional addiction. MYC amplification appears frequently in many common tumor types and is associated with aggressive disease.
Percentage of Tumors in the National Cancer Institute’s the Cancer Genome Atlas (TCGA) Dataset With Copy Number Gains of MYC, MYCN or MYCL
We believe that CDK9 is an attractive therapeutic target in transcriptionally addicted cancers, and specifically MYC-amplified solid tumors, due to its essential role in transcriptional elongation. MYC is critically dependent on CDK9 in order to drive transcription of downstream target genes and effect the oncogenic program. Additionally, a high rate of transcription is required to maintain elevated MYC protein levels, which creates an additional upstream dependency on large quantities of CDK9. These upstream and downstream dependencies are particularly acute in tumors with MYC genomic amplification, as these cells are addicted to high levels of MYC.
19
MYC Upstream and Downstream Regulation
In vivo efficacy modeling with KB-0742 was initially conducted in a MYC-dependent AML xenograft model, MV4-11, and demonstrated dose dependent tumor growth inhibition at well-tolerated doses as measured by body weight. Assessment of PD markers in tumor also showed dose-dependent effects, including levels of pSer2 (a direct phosphorylation target of CDK9), MCL1 (an anti-apoptotic oncoprotein known to depend on CDK9) and cleaved PARP (a marker of apoptotic cell death). Importantly, we demonstrated that an intermittent dosing strategy of 60 mg/kg on a three days on / four days off schedule showed equivalent activity compared to the same amount of drug delivered with continuous daily dosing (25 mg/kg QD). We believe that intermittent dosing may be better tolerated clinically and has the potential to improve therapeutic index for CDK9 inhibition.
20
MYC-Driven Xenograft Model
While the initial xenograft data in the AML cell line are encouraging, we believe that a greater therapeutic opportunity lies in treating MYC-amplified solid tumors. Based on large scale in vitro viability profiling of KB-0742, we observed that MYC genomic amplification is correlated with increased sensitivity to compound treatment in non-small cell lung cancer tumors.
Differential Sensitivity in MYC-Amplified NSCLC Cell Lines
Additional in vivo experiments are ongoing to inform selection of appropriate patient populations for clinical development of KB-0742.
Differentiated Opportunity
We believe that KB-0742 represents a differentiated opportunity for targeting CDK9 based on its selectivity profile, oral bioavailability and other attractive pharmacologic properties.
Multiple CDK9 inhibitors are currently being investigated clinically; however, clinical results published to date have shown limited therapeutic index and, to our knowledge, none has advanced into late-stage clinical trials. We believe that three primary factors differentiate KB-0742 and our translational strategy, and may enable an enhanced potential therapeutic index relative to other programs:
21
CDK Selectivity. CDK9 bears a high degree of structural similarity to other CDK family members, and nearly all previously reported CDK9 inhibitors possess significant inhibitory activity on other CDKs, including cell cycle CDKs. Even many purportedly selective CDK9 inhibitors have shown a relatively narrow fold-selectivity in biochemical assays, which may not be sufficient to avoid off-target activity at the physiologically relevant concentrations achieved in a clinical setting. This off-target activity may meaningfully contribute to the clinical profile of these molecules, and in particular we believe that a lack of selectivity against cell-cycle CDKs may introduce safety liabilities unrelated to the transcriptional mechanism of CDK9. In contrast, KB-0742 was highly selective for CDK9 over other CDK family members, potentially enabling a superior opportunity to achieve therapeutically-relevant target coverage in vivo without meaningful inhibition of off-target CDKs.
Biochemical Assay Panel Showed High Selectivity of KB-0742 for CDK9 over Other CDK Family Members
PK Profile and Dosing Schedule. Because of the essential role of CDK9 in all normal tissues, it is critical to optimize dosing schedule and duration of target coverage in order to achieve anti-tumor activity without eliciting undue toxicity in normal tissues. Based on our team’s prior experience developing anti-cancer agents targeting epigenetic targets, we intend to pursue an intermittent dosing strategy, with the goal of maintaining a consistent level of target coverage for several days followed by a drug holiday to allow for recovery in normal tissue. Many other CDK9 inhibitors possess short half-life or are administered intravenously, resulting either in pulsatile target coverage or short overall duration of target coverage. By contrast, KB-0742 has demonstrated oral bioavailability in preclinical studies, and PK modeling indicates a potential long half-life in humans. We believe that this is an attractive profile and affords the flexibility to establish a therapeutic index by varying dose and schedule to achieve optimal target coverage in tumor.
Patient Selection. We believe that the underlying biology of a tumor and degree of transcriptional addiction is critical in determining its sensitivity to CDK9 inhibition, and by extension, therapeutic index. Rather than selecting patients solely based on a tumor’s tissue of origin, we intend to take a differentiated approach to clinical translation by focusing on development in patient populations with clear genomic markers of transcriptional addiction including MYC amplification.
Development Strategy
The FDA cleared our IND for KB-0742 in December 2020. In February 2021, we initiated our Phase 1/2 clinical trial of KB-0742 in cancer patients to evaluate its safety, PK and PD across multiple dose levels to identify a recommended dose and schedule. After identifying the recommended dose level and dosing schedule, we intend to enroll expansion cohorts of patients with MYC-amplified solid tumors and other transcriptionally addicted tumor types, with the goal of assessing safety and PD response in these patient populations.
22
Two-Stage Phase 1/2 Dose Escalation Clinical Trial
We are enrolling the initial dose escalation cohorts on a three-days on/four-days off intermittent dosing schedule. We believe that this schedule flexibility, enabled by an oral dosing formulation, is critical for identifying an optimal dosing strategy that balances target coverage and anti-tumor activity with safety and tolerability.
Following identification of a recommended Phase 2 clinical trial dose and schedule, we intend to enroll expansion cohorts in one or more biomarker-defined patient populations with transcriptionally addicted cancers, beginning with MYC-amplified solid tumors regardless of tissue of origin. We may enroll an additional cohort of soft tissue sarcoma patients with transcription factor fusions and patients with chordoma, an incurable solid tumor addicted to the brachyury transcription factor. Although patients with these tumor types are relatively rare, we believe it is feasible to enroll such patients at major academic centers, which may provide a unique opportunity to demonstrate proof of concept for KB-0742. Clinical results from these expansion cohorts will inform the future development and registration strategy for KB-0742.
Background on our Research and Development Strategy: Targeting the Activity of Oncogenic Transcription Factors through their Transcription Regulatory Networks (TRNs)
Transcription factors are proteins that bind to specific DNA sequences on the genome and control how sets of genes are turned on and off. This ability to exert systematic control on gene expression underlies the functional importance of transcription factors and consequently, transcription factor activity is recurrently deregulated in many human cancers. This is exemplified by two transcription factors: MYC, the most commonly amplified oncogene, and p53, the most commonly inactivated tumor suppressor gene. Together, these two genes account for two thirds of all human cancers. The human genome encodes more than 500 transcription factors, of which more than 30% have been functionally implicated in cancer, including in recent pan-cancer genetic screens that identify highly selective tumor dependencies.
While there are examples of approved therapies that directly target transcription factor activity (such as those targeting the nuclear hormone family of transcription factors which contain ligand binding domains, or those which act as molecular glues that degrade zinc finger transcription factors), transcription factors as a class remain challenging drug targets. Traditional drug discovery approaches have struggled to target transcription factors for two main reasons. First, most are considered intrinsically disordered proteins, which means that when recombinantly purified they fail to adopt a defined structure, rendering most biochemical and biophysical drug screening approaches unusable. Second, most transcription factors lack active sites or “ligandable” pockets within their protein structure that can be used to modulate their activity. The core biological activity of transcription factors is their ability to recruit cofactors and form large multi-subunit protein complexes on the genome; however, it is only in a cellular context that transcription factors bind to such cofactors and form a unique and defined protein structure. To overcome these two challenges, we believe transcription factors must be drugged in their appropriate physiological context.
23
Our approach to drug discovery addresses this by mapping and understanding transcription factor activity within the context of its TRN. Within a tumor, a dysregulated network of hundreds of regulatory proteins, including cell-signaling proteins, transcription factors, epigenetic regulators and core transcriptional machinery, coordinate to drive the oncogenic gene expression program. These interactions are dynamic, interdependent and frequently contain redundant pathways, compensatory mechanisms or feedback loops that may drive resistance to targeted therapies. Collectively these hundreds of interactions make up an oncogenic TRN.
By mapping a specific oncogenic TRN, we believe we are better able to understand the context of transcription factor dependency, which can inform both model selection at the discovery stage and patient biomarker strategy in the clinic. Additionally, TRN maps enumerate the specific inputs and outputs of gene expression, which can provide insights into how TRNs can be perturbed as well as direct readouts of TRN perturbation. Such direct readouts are crucial in enabling the development of assays to identify on-target TRN perturbation and to distinguish selective inhibition of transcription factor activity from less desirable global inhibition of transcription.
Understanding the structure of a TRN also helps inform our target selection. In an oncogenic TRN, many parallel signals and feedback loops converge to define and drive cancer. Dysregulated transcription factors are the proteins that directly control aberrant transcription of the genome and are critical nodes in oncogenic TRNs. These TRNs may also contain additional critical nodes of signaling or epigenetic regulation that play an essential role in perpetuating the oncogenic TRN. Our core hypothesis is that TRNs are most easily targeted by drugging their critical nodes. We believe these critical nodes present attractive therapeutic targets that expand the opportunity to target transcription factor activity in cancer. By potentially collapsing the oncogenic TRN, therapies directed to these targets hold the promise of limiting potential mechanisms for resistance.
The figure below illustrates an example TRN and shows how the structure of a TRN can be altered in a tumor specific context. In this diagram, nodes represent distinct proteins and edges represent functional, regulatory, or genetic interactions. Upregulation of oncogenic signaling can alter the activity of nodes and edges (shown in red) leading to oncogenic activation of gene expression at tumor specific loci across the genome. These subnetworks within the TRN are associated with tumor specific activity and are likely to contain critical nodes, proteins that play an outsized role in maintaining a tumor specific TRN and are relied upon for the survival of the tumor. Critical nodes may be points of convergence for multiple signaling pathways, components of positive feedback loops, or effector proteins that regulate many other processes. Since transcription factors themselves can regulate many hundreds or more genes, transcription factors are often critical nodes within TRNs.

Example Output of Mapping TRN in Oncogenic versus Normal Context
Our Product Engine
Our differentiated product comprises three interconnected components. First, we integrate diverse multiomic data from cancer model systems with clinical real-world evidence to map the TRN of interest. Next, we apply our expertise in systems biology and drug discovery to define the mechanistic basis of TRN tumor dependency. Third, we use this tumor dependency information to identify small molecule modulators in one of two ways: either through use of our proprietary SMM screening platform in an “unbiased” manner, or through a more “biased” approach where we direct our screening efforts against identified TRN critical nodes. These elements of our product engine are shown in the figure below.
25
Mapping TRNs by Integrating multiomic data and real-world evidence
TRN maps represent the summation of multiple regulatory layers (genetic, signaling, chromatin, epigenomic, protein-protein interaction) that converge in the nucleus to establish and maintain the cell’s gene expression program. In mapping TRNs, we address two major challenges that enable us to better generate actionable drug discovery insights that drive our drug discovery efforts.
First, we seek to identify TRN maps in the appropriate context that captures their tumor-specific deregulation. As an example, to map the MYC TRN, we analyze how MYC amplification rewires the tumor cell TRN to create positive feedback loops that stabilize and upregulate MYC activity in a manner not seen in normal cells. To ensure that the TRN maps faithfully recapitulate true patient tumor biology, we integrate pan-cancer multiomic data, which helps us understand a broader and more defined TRN map, with clinical real-world evidence drawn from thousands of cancer patients. This also lays the foundation for later patient selection and biomarker development.
Defining the mechanistic basis of TRN tumor dependencies
Our initial TRN maps, like many big-data networks, contain many thousands of nodes and edges and are too complex to be immediately actionable. To address this, we have developed computational biology capabilities that we deploy to identify direct transcription factor regulatory modules that we validate using high throughput functional perturbations. These modules allow us to transform our TRN maps from being associative and correlative to causal and predictive. This enables us to understand the consequences of perturbing individual nodes in the TRN, which in turn can drive assay development and the nomination of critical nodes in target selection.
We believe our approach to TRN mapping may reveal actionable critical nodes throughout the TRN, including lineage-defining transcription factors, epigenetic factors and non-redundant pathway or co-factor dependencies required to execute the oncogenic program. This is especially valuable when targeting dysregulated transcription factors that act in a highly context-dependent manner and are difficult to target using conventional methods.
Identify TRN modulators by using our SMM screening platform or by direct targeting of critical nodes
Our proprietary SMM screening platform addresses the historical challenges of context-dependent structures and complexes by allowing us to conduct a high throughput screen for protein complex binders directly in a tumor cell lysate.
Because SMM lysate screens probe the entire target protein interactome in a single assay, SMM hits have the potential to engage the target protein and its complexes through at least three distinct binding modes:
26
•Direct binder. These molecules may directly engage the target protein either at an active domain or an allosteric site.
•PPI Modulator. These molecules may bind a pocket or groove that is created by a protein-protein interface in complexes containing the target protein.
•Co-factor binder. These molecules may bind an essential co-factor of the target protein.
Small Molecule Microarray Identifies Binders to TRN Constituents
Hits derived from an SMM screen have the potential to bind different members of the target protein complex and act through a variety of mechanisms. Our approach is to identify selective modulators of TRNs rather than modulators that globally alter transcription. We hypothesize that selective on-target TRN modulators should have a better therapeutic index in that they will selectively inhibit TRN-driven oncogenic gene expression programs while sparing normal transcription. Our ability to properly characterize the transcriptional selectivity of small molecule perturbations will be crucial in developing and optimizing TRN modulators and is akin to assessing the substrate selectivity and off targets of more traditional drugs like enzymatic inhibitors. In contrast to traditional drug discovery triages, which focus on identifying compounds with a particular activity or profile, SMM hit triage must account for multiple distinct hit profiles.
From our context dependent TRN maps, one way that we characterize SMM hits is by generating and experimentally validating signatures of gene expression response that can delineate various forms of TRN perturbation ranging from degradation of a key transcription factor to inhibition of cofactors in upstream signaling pathways. As shown in the figure below, we generate signatures of approximately 24-48 genes whose change in expression we know to be associated with known perturbations of the TRN, such as genetic knockdown of a key transcription factor or chemical inhibition of a cofactor. Signatures include TRN responsive genes as well as control genes, such as GAPDH, which we know to be invariant to TRN perturbation. We use NanoString gene expression to profile how SMM hits impact these TRN signatures in a high throughput manner. For each gene in a signature, NanoString generates a hybridization reporter with a unique fluorescent barcode, as seen on the left. These reporters enable a multiplexed readout of mRNA abundance of these signature genes which allow us to profile the gene expression changes caused by SMM hits. This robust transcriptomic profiling enables us to rapidly advance hits that selectively perturb the oncogenic TRN and exclude compounds with dominant off-target/off-pathway activity, as depicted in the figure below.
27
Hit Prioritization for On-target TRN Activity
The second way we characterize SMM hits is by investigating specific mechanisms of action that emerged as critical nodes from our TRN maps, including for example assaying SMM hits for their ability to disrupt a protein-protein interaction or their ability to inhibit a druggable cofactor. In any given SMM TRN screen we may have multiple of these critical node mechanisms that we can bias our hit triage towards. Having two methods of hit characterization allows us to characterize both hits that have on-target gene expression activity in an unbiased manner as well as to find hits that modulate predefined mechanisms of interest.
In addition to identifying functional binders using gene expression signatures, we mine our SMM hits for non-functional binders to known critical node proteins. Because they bind to the target protein while also being covalently attached to the array slide via a chemical linker, SMM hits are well positioned to be transformed into heterobifunctional molecules. The attachment site of this chemical linker is used as a starting point to rapidly functionalize these SMM hits, including converting these hits into heterobifunctional proteolysis targeting chimera (PROTAC) degraders, in order to achieve TRN modulatory activity.
Independent of our SMM screen, we have used other aspects of our product engine to identify critical nodes for which there are existing drugs or chemical matter. For example, we acquired the SYK inhibitor portfolio from Gilead because we perceived an opportunity to target a dysregulated AML TRN driven by high levels of the HOX/MEIS transcription factor family. From our mapping of this TRN, we identified mutations to NPM1 (NPM1c) as directly driving high HOX/MEIS levels and SYK as participating in a key positive feedback loop with HOX/MEIS. This provided a mechanistic basis for SYK dependency in the NPM1c mutant AML patient subset. We used detection of NPM1c mutations as a clinical biomarker for patient selection and from our HOX/MEIS TRN map we developed a more refined signature of on-target SYK inhibition and its downstream consequences for use in our pharmacodynamics measurements. Our product engine enables us to take different approaches to modulating TRNs and identify context-specific critical nodes that can be more easily acted upon either by traditional drug discovery approaches or through existing external programs.
Optimizing Lead TRN Modulator Molecules
Once we have identified a lead molecule, we investigate the connection between molecular characteristics and target engagement to refine or optimize the pharmacological properties of the molecule to match the desired clinical product profile. We employ our robust medicinal chemistry, computational chemistry and assay development capabilities to support such lead optimization.
28
We tailor our lead optimization strategy to the specific program that gave rise to the lead molecule. We design structure-activity relationship studies to guide optimization toward a specific transcriptional signature in relevant cancer cell lines. For hits with a known binding site and ordered structure, we also leverage computational modeling, structure-based drug design and a suite of biochemical or biophysical assays to rapidly advance lead optimization programs. For hits against historically challenging targets not amenable to biochemical or biophysical screening assays, we have the capability to advance chemistry programs using structure-blind medicinal chemistry approaches that are informed by transcriptional readouts in cell-based assays.
Our Approach to Clinical Trial Design
We leverage our extensive computational biology capabilities to identify predictive biomarkers for drug response and key pharmacodynamic markers of activity within the oncogenic TRN. We then seek to establish in preclinical models the required extent and duration of target coverage required to achieve clinical efficacy without eliciting undue toxicity in normal tissue. For example, while continuous dosing strategies may be appropriate for certain targets, such as SYK, intermittent dosing strategies may be essential for establishing a therapeutic index for other targets, such as CDK9.
We apply this understanding of predictive markers and the pharmacodynamic/efficacy relationship to design early clinical studies that can efficiently identify an optimal dose and dosing schedule for a given product candidate, and potentially achieve clinical proof of concept in a biomarker-defined patient population. This targeted approach may also enable a more efficient late-stage clinical development and registration strategy by focusing on the patients most likely to benefit from treatment and potentially to pursue more efficient regulatory approval pathways.
Discovery Programs
We continually invest in early discovery efforts utilizing our proprietary product engine, with the goal of expanding our pipeline of future product candidates. Our current efforts are focused on four cancer types where dysregulated transcriptional regulatory networks (TRNs) play a central role. We believe that we can develop a deep understanding of the underlying cancer dependency, engineer robust systems to characterize perturbation signatures, and identify multiple potential opportunities for therapeutic intervention through modulation of key TRN components. We select our discovery targets based on multiple scientific, translational and competitive considerations, prioritizing those where dependency has been demonstrated in a defined patient population with high unmet medical need, and where we believe we can design an efficient early clinical translation strategy based upon our understanding of the disease biology.
•HOX/MEIS, MYB, IRF4 and Hematologic Malignancies. Despite significant advances in medical management of patients with hematologic malignancies, the majority of patients eventually progress through standard of care therapy and long-term outcomes remain poor. There is a demonstrated need for novel and more durable treatments for hematologic malignancies, including AML and multiple myeloma. In addition to our clinical SYK inhibitor program in HOX/MEIS-high AML, we are actively conducting discovery efforts targeting MYB, a key lineage transcription factor in early hematopoiesis that is dysregulated in leukemia and interacts with many known leukemia driver genes. We are also actively conducting discovery efforts on IRF4, which is a major driver of multiple myeloma and which is downstream of the primary resistance pathway for thalidomide analogs.
•AR and Prostate Cancer. Dysregulation of the androgen receptor (AR) TRN is a primary driver of prostate cancer. Multiple approved products target the AR TRN by directly inhibiting AR, such as enzalutamide or apalutamide, or by inhibiting androgen biosynthesis, such as abiraterone acetate. Although androgen deprivation therapy is effective in controlling disease, a large number of patients ultimately develop therapy resistance and succumb to castration-resistant prostate cancers. Castration resistance is commonly induced by certain AR variants, such as ARv7, that lack the ligand binding domain and consequently are no longer considered conventionally druggable. Critically, these AR variant tumors still are driven by and depend on increased activity of the AR TRN. Our discovery efforts seek to identify novel modulators of AR TRN activity that are effective in tumor lines expressing AR variants.
•MYC and MYC-Driven Cancers. The MYC family of dysregulated transcription factors is among the small number of proto-oncogenes capable of driving tumor formation and growth in a wide variety of contexts. In normal cells, MYC acts at the nexus of multiple signaling pathways to coordinate gene expression
29
programs associated with cell growth, metabolism and proliferation. In tumors, MYC dysregulation is defined by increased levels and activity of the full length MYC transcription factor. MYC is dysregulated in a significant proportion of malignancies and its dysregulation is associated with aggressive disease and poor clinical outcomes. As such, targeting MYC has long been considered one of the great challenges in developing cancer therapeutics. In many MYC dysregulated tumors, oncogenic driver events rewire the MYC TRN to introduce positive feedback loops that lead to runaway MYC activation. In addition to our CDK9 program, which focuses on the treatment of patients with MYC-amplified solid tumors, we are focusing discovery efforts to find additional modulators of the MYC TRN.
•ASCL1 and SCNC. Tumor cells can transition between cell states, or subtypes, in response to therapy as a means of acquiring resistance and becoming more aggressive. In particular, many solid tumors adapt to and eventually overcome standard of care therapy as a result of transitions into a SCNC subtype. SCNC state transitions are common in small cell lung cancer, and are also observed in neuroblastoma, prostate cancer, and pancreatic cancer, and patients with these cancers face a very poor prognosis. The transcription factor ASCL1 has emerged as a critical node in the SCNC TRN. It is both a biomarker of the SCNC subtype and a demonstrated dependency in these cancers. Our discovery efforts currently focus on identifying modulators of ASCL1 transcription factor activity within the SCNC TRN.
Future Opportunities
While many opportunities remain within oncology, dysregulated TRNs also play a central role in many other disease states. Future applications of our differentiated product engine in the immunology field may hold particular promise, especially with respect to targeting TRNs that influence the tumor microenvironment and anti-tumor immune response or tolerance. As our discovery organization continues to grow, we intend to regularly re-evaluate our discovery pipeline and seek to identify additional opportunities to fully exploit our differentiated product engine.
Strategic Agreements
Tempus R&D Services Agreement
In October 2021, we entered into an agreement for research and development services (Tempus Agreement) with Tempus Labs, Inc. (Tempus), pursuant to which Tempus agreed to provide us with research and development services for a period of three years . The three primary services are analytical services, data licensing, and organoid services. We intend to utilize the services contemplated under the Tempus Agreement to advance the development of KB-0742 and lanraplenib.
In consideration for the access to the services throughout the term of the Tempus Agreement, we have agreed to pay an annual minimum commitment of $1.5 million in year one, $2.0 million in year two, and $2.5 million in year three. Payments are made in quarterly installments. As of December 31, 2021, we have not made any payments under the Tempus Agreement.
In addition, we are required to make milestone payments upon successful achievement of certain regulatory milestones for KB-0742, lanraplenib, and other discovery pipeline compounds up to a combined maximum of $22.4 million. For each milestone payment that becomes due, we have the right to pay up to 50 % of such milestone payment amount in shares of our common stock as long as certain regulatory requirements are met.
30
Gilead Asset Purchase Agreement
In July 2020, we entered into the Gilead Asset Purchase Agreement, pursuant to which we acquired certain assets from and assumed certain liabilities of Gilead related to entospletinib and lanraplenib, and patents and other intellectual property covering or related to the development, manufacture and commercialization of entospletinib and lanraplenib.
In consideration for such assets, on the date of the Gilead Asset Purchase Agreement, we made a $3.0 million upfront cash payment and issued a $3.0 million principal amount convertible promissory note to Gilead (Gilead Note), the material terms of which are summarized below. We also made a $0.7 million payment to reimburse Gilead for certain liabilities we assumed pursuant to the Gilead Asset Purchase Agreement. In addition, we are required to make milestone payments upon successful achievement of certain regulatory and sales milestones for entospletinib, lanraplenib and other SYK inhibitor compounds covered by the patent rights acquired pursuant to the Gilead Asset Purchase Agreement and developed by us as a back-up to entospletinib or lanraplenib (Other Compounds). Upon initiation of the our registrational Phase 3 clinical trial of entospletinib in combination with induction chemotherapy in acute myeloid leukemia patients with NPM1 mutations in December 2021, we paid a milestone to Gilead of $29.0 million. Upon successful completion of certain other regulatory milestones in the United States, European Union and United Kingdom for entospletinib, lanraplenib and any Other Compounds, across up to two distinct indications, we will be required to pay to Gilead an aggregate total of $51.3 million. Upon achieving certain thresholds for the aggregate annual net sales of entospletinib, lanraplenib and any Other Compounds combined, we would owe to Gilead potential milestone payments totaling $115.0 million.
Gilead is also eligible to receive (i) tiered marginal royalties ranging from the very low-teens to high-teens on annual worldwide net sales of entospletinib, (ii) tiered marginal royalties ranging from high-single digits to the mid-teens on annual worldwide net sales of lanraplenib and (iii) tiered marginal royalties ranging from the low single digits to mid-single digits on annual worldwide net sales of any Other Compounds. The royalties in the foregoing clauses are subject to reduction, on a country-by-country basis, for products not covered by certain claims within the assigned patents, for generic entry and, in the case of entospletinib and lanraplenib, for any royalties paid for future licenses of third party intellectual property required to develop or commercialize entospletinib or lanraplenib. Our royalty obligation with respect to a given product in a given country begins upon the first commercial sale of such product in such country and ends on the latest of (i) expiration of the last claim of a defined set of the assigned patent rights covering such product in such country, (ii) loss of exclusive data or marketing rights to such product in such country or (iii) 10 years from the first commercial sale of such product in such country.
Under the Gilead Asset Purchase Agreement, we are required to use commercially reasonable efforts to develop, obtain regulatory approval for and commercialize either entospletinib or lanraplenib.
Gilead is required, subject to certain limitations, to indemnify us against damages arising out of any breach in the representations or warranties made by Gilead, any breach of a covenant by Gilead, any use or exploitation of the acquired assets by or on behalf of Gilead prior to the closing of the Gilead Asset Purchase Agreement, or any liability not specifically assumed by us under the Gilead Asset Purchase Agreement, subject to certain caps. Likewise, we are required, subject to certain limitations, to indemnify Gilead against damages arising out of any breach of our representations and warranties, any breach of a covenant made in the agreement, any use or exploitation of the acquired assets by us or on our behalf on or after the closing of the Gilead Asset Purchase Agreement, or any assumed liability, subject to certain caps.
The Gilead Note accrued interest at a rate of 6% per year, compounded annually, and had a maturity date of July 14, 2022. The Gilead Note, including unpaid accrued interest, was settled in exchange for 188,567 shares of common stock in connection with the closing of our IPO at a settlement price of $16.15 per share, which is equal to 85% of the price per share to the public in our IPO.
31
Harvard License Agreement
In January 2018, we entered into a license agreement with President and Fellows of Harvard College (Harvard), pursuant to which Harvard granted us a non-exclusive, worldwide, royalty-free license to certain patent rights covering aspects of our SMM platform. We paid a one-time license fee in the amount of $10,000 on the date of the agreement and an annual license maintenance fee of $20,000 on each of the first two anniversaries. We are required to pay $25,000 on each subsequent anniversary until the last to expire of any valid claim included in the licensed patents.
Unless earlier terminated in accordance with the agreement, the agreement will continue until the last to expire of any valid claim of the licensed patents. In addition, the agreement can be terminated (i) by either party for the other party’s material breach that remains uncured for 30 days after written notice, (ii) by Harvard if we fail to meet certain insurance obligations immediately without notice, and for certain insolvency-related events upon notice, and (iii) by us, for any reason, upon 60 days’ written notice.
Sales and Marketing
We intend to build a commercial infrastructure to support sales of any of our approved products. We expect to manage sales, marketing and distribution through internal resources and third-party relationships. While we may commit significant financial and management resources to commercial activities, we will also consider collaborating with one or more pharmaceutical companies to enhance our commercial capabilities.
Manufacturing
We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We currently rely, and expect to continue to rely for the foreseeable future, on third parties for the manufacture of our product candidates for preclinical and clinical testing, as well as for commercial manufacture of any products that we may commercialize. In this regard, while we have purchased initial inventory of active pharmaceutical ingredients (APIs) and clinical drug supply for entospletinib and lanraplenib from Gilead under the Gilead Asset Purchase Agreement, we will need to obtain further supplies of APIs and clinical drug supply for entospletinib, lanraplenib and KB-0742 from third-party manufacturers. We are initially obtaining our supplies from manufacturers on a purchase order basis without long-term supply arrangements in place. We do not currently have arrangements in place for redundant supply for APIs and drug product. For all of our product candidates, we intend to identify and qualify manufacturers to provide the APIs and drug product prior to submission of an NDA to the FDA or other marketing authorization applications to other regulatory authorities.
All our product candidates are compounds of low molecular weight, generally called small molecules. They can be manufactured from readily available starting materials in reliable and reproducible synthetic processes that are amenable to scale-up and do not require specialized equipment in the manufacturing process. We expect to continue to develop product candidates that can be produced cost-effectively at contract manufacturing facilities.
Competition
The pharmaceutical and biotechnology industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary drugs. We operate in the segments of the pharmaceutical, biotechnology and other related markets that address inhibition of kinases and targeting transcriptional regulation in cancer. While we believe that our technology, development experience and scientific knowledge provide us with competitive advantages we hope to exploit, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and ultimately commercialize will compete with existing products and new products that may become available in the future.
32
In the case of our lead product candidate, entospletinib, or lanraplenib, there are currently no approved products on the market that address the HOX/MEIS-high or NPM1 mutations subset of AML patients. However, there are product candidates that are currently in clinical development which, if approved, could compete or potentially be complementary with entosplentinib or lanraplenib including: (i) HMPL-523, a SYK inhibitor being developed by Hutchison Medipharma Ltd. that is in Phase 1 evaluation in hematologic malignancies; (ii) product candidates in early clinical development that target the interaction between MLL and MENIN in MLL-r and AML patients with NPM1 mutations, including (a) SNDX-5613, being developed by Syndax Pharmaceuticals, Inc. in a Phase 1 clinical trial as monotherapy in relapsed or refractory AML in patients with MLL-r/KMT2A gene rearrangement or NPM1 mutations; (b) KO-539, being developed by Kura Oncology, Inc. in a Phase 1 clinical trial as monotherapy in relapsed or refractory AML, (c) DS-1594, being developed by Daiichi Sankyo Company in a Phase 1 clinical trial with or without azacitidine/venetoclax in relapsed/refractory AML, and (d) JNJ-75276617, being developed by Janssen Research & Development, LLC in a Phase 1 clinical trial in acute leukemias; and (iii) product candidates that address the subset of AML patients with FLT3 mutations and are currently in development in combination with FLT3 inhibitors, including (a) venetoclax, a BCL-2 inhibitor being developed by Abbvie, and (b) CPX-351, a liposomal formulation of daunorubicin and cytarabine being developed by Jazz Pharmaceuticals.
If we are successful in developing and receiving approval for KB-0742, we expect it would compete against various multi-CDK inhibitors that are currently in early-stage clinical development if they are ultimately approved, including: AZD4573, being developed by AstraZeneca; TP-1287 (alvocidib), being developed by Tolero Pharmaceuticals; fadraciclib (CYC-065), being developed by Cyclacel Pharmaceuticals; zotiraciclib, being developed by the National Cancer Institute; dinaciclib, being developed by Merck & Co.; and voruciclib, being developed by MEI Pharma. We also expect it to compete against VIP152, a PTEFb/CDK9 inhibitor in early-stage clinical development by Vincerx Pharma, Inc., and PRT2527, a CDK9 inhibitor in preclinical development by Prelude Therapeutics.
Many of the companies against which we may ultimately compete have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a smaller number of our potential competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These companies also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient enrollment in clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.
We could see a reduction or elimination in our commercial opportunity if other companies develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient to administer, are less expensive or with a more favorable label than any of our product candidates. These companies also may obtain FDA or other regulatory approval for their drugs more rapidly than we may obtain approval for ours, which could result in their establishing a strong market position before we are able to enter the market. The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, safety, convenience, price, the effectiveness of companion diagnostics, the level of generic competition and the availability of reimbursement from government and other third-party payors.
Intellectual Property
Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our most advanced product candidates, entospletinib and lanraplenib, our development stage product, KB-0742, our future product candidates, as well as novel discoveries, product development technologies, and know-how. Our commercial success also depends in part on our ability to operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to develop and maintain protection of our proprietary position and freedom to operate by, among other means, filing and prosecuting, or in-licensing or acquiring U.S. and foreign patents and patent applications covering those products, technologies, inventions, and improvements that are important to our business.
We also rely on trademarks, trade secrets, know-how, continuing technological innovation, confidentiality agreements, and invention assignment agreements to develop and maintain our proprietary position. The confidentiality agreements are designed to protect our proprietary information and the invention assignment
33
agreements are designed to grant us ownership of technologies that are developed by our employees, consultants, or other third parties. We seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in our agreements and security measures, either may be breached, and we may not have adequate remedies. In addition, our trade secrets may otherwise become known or independently discovered by competitors.
With respect to both licensed and company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our commercial products and methods of using and manufacturing the same.
We are actively building our intellectual property portfolio around our product candidates and our discovery programs, based on our own intellectual property as well as licensed intellectual property. Following the execution of the Gilead Asset Purchase Agreement, we are the owners of multiple patents and patent applications in the United States and worldwide directed to the composition of matter and methods of use of entospletinib and lanraplenib and other related SYK inhibitor compounds.
Our patent portfolio in general includes patents and patent applications directed to our lead product candidate, entospletinib, as well as to lanraplenib, KB-0742 and our other research-stage candidates, all of which are solely owned by us.
As of February 1, 2022, our patent portfolio related to entospletinib included over 17 issued U.S. patents, 144 issued or granted foreign patents, and 16 pending U.S. and foreign patent applications, claiming entospletinib as a composition of matter, formulations, polymorphic forms or their methods of use or manufacture, all with nominal terms between 2029 and 2037. Nominal patent terms are determined as 20 years from the earliest nonprovisional filing date to which priority is claimed, and do not take into account extensions that are or may be available.
With respect to lanraplenib as of February 1, 2022, our patent portfolio included seven issued U.S. patents, 98 issued or granted foreign patents, and 36 pending U.S. and foreign patent applications claiming lanraplenib as a composition-of-matter, methods of using lanraplenib, and its polymorphic forms and their use, all with nominal terms extending to between 2034 and 2037.
With respect to KB-0742, we have one U.S. patent and 42 pending U.S and foreign patent applications directed to the KB-0742 compound, compositions, methods of treating CDK9-mediated diseases with KB-0742, analogs and polymorphic forms of KB-0742, and other research-stage candidate compounds that modulate CDK9 activity.
Our SMM platform component of our product engine is protected both by certain patents that we have licensed under the Harvard License, as well as proprietary know-how we have generated, including with respect to its use in drug discovery screening against transcription factors in tumor cell lysate. We continue to assess the extent to which we may seek additional patent protection for aspects of our product engine or instead maintain such intellectual property as trade secrets.
The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the date of filing of the first non-provisional application to which priority is claimed. In the United States, patent term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the United States Patent and Trademark Office in granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier-filed patent. In the United States, the term of a patent that covers an FDA-approved drug may also be eligible for a patent term extension of up to five years under the Hatch-Waxman Act, which is designed to compensate for the patent term lost during the FDA regulatory review process. The length of the patent term extension is calculated based on the length of time it takes for regulatory review. A patent term extension under the Hatch-Waxman Act cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent applicable to an approved drug may be restored. Moreover, a patent can only be restored once, and thus, if a single patent is applicable to multiple products, it can only be extended based on one product. Similar provisions are available in Europe and certain other foreign jurisdictions to extend the term of a patent that covers an approved drug.
34
Government Regulation and Product Approval
Government authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing and export and import of products such as those we are developing. A new drug must be approved by the FDA through the NDA process before it may be legally marketed in the United States.
U.S. Drug Development Process
In the United States, the FDA regulates drugs under the federal Food, Drug, and Cosmetic Act (FDCA), and its implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.
The process required by the FDA before a drug may be marketed in the United States generally involves the following:
•completion of preclinical laboratory tests, animal studies and formulation studies in accordance with FDA’s good laboratory practice requirements and other applicable regulations;
•submission to the FDA of an IND, which must become effective before human clinical trials may begin;
•approval by an independent IRB ethics committee at each clinical site before each trial may be initiated;
•performance of adequate and well-controlled human clinical trials in accordance with GCP requirements to establish the safety and efficacy of the proposed drug for its intended use;
•submission to the FDA of an NDA after completion of all pivotal trials;
•satisfactory completion of an FDA advisory committee review, if applicable;
•satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength, quality and purity, and of selected clinical investigation sites to assess compliance with GCPs; and
•FDA review and approval of the NDA to permit commercial marketing of the product for particular indications for use in the United States.
Prior to beginning the first clinical trial with a product candidate in the United States, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. The IND also includes results of animal and in vitro studies assessing the toxicology, PK, pharmacology, and PD characteristics of the product; chemistry, manufacturing, and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.
35
Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site and must monitor the study until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.
Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:
•Phase 1: The product candidate is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.
•Phase 2: The product candidate is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.
•Phase 3: The product candidate is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval.
Post-approval trials, sometimes referred to as Phase 4 studies, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA.
The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. In addition, some clinical trials are overseen by an independent group of qualified experts organized by the sponsor, known as a data safety monitoring board or committee. Depending on its charter, this group may determine whether a trial may move forward at designated check points based on access to certain data from the trial.
During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at the end of Phase 2, and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice, and for the sponsor and the FDA to reach agreement on the next phase of development. Sponsors typically use the meetings at the end of the Phase 2 trial to discuss Phase 2 clinical results and present plans for the pivotal Phase 3 clinical trials that they believe will support approval of the new drug.
36
Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.
While the IND is active and before approval, progress reports summarizing the results of the clinical trials and nonclinical studies performed since the last progress report must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and investigators for serious and unexpected suspected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs, findings from animal or in vitro testing suggesting a significant risk to humans, and any clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the protocol or investigator brochure.
U.S. Review and Approval Process
Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, preclinical and other non-clinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the product. The submission of an NDA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain limited circumstances. Additionally, no user fees are assessed on NDAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.
The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality and purity. Under the Prescription Drug User Fee Act (PDUFA), guidelines that are currently in effect, the FDA has a goal of ten months from the date of “filing” of a standard NDA for a new molecular entity to review and act on the submission. This review typically takes twelve months from the date the NDA is submitted to FDA because the FDA has approximately two months to make a “filing” decision after it the application is submitted. The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review The FDA may request additional information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing.
The FDA may refer an application for a novel drug to an advisory committee. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Before approving an NDA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP and adequate to assure consistent production of the product within required specifications. Additionally, before approving a NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCPs. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
37
After the FDA evaluates an NDA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete, and the application will not be approved in its present form. A Complete Response Letter usually describes the specific deficiencies in the NDA identified by the FDA and may require additional clinical data, such as an additional pivotal Phase 3 trial or other significant and time-consuming requirements related to clinical trials, nonclinical studies or manufacturing. If a Complete Response Letter is issued, the sponsor must resubmit the NDA or, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information are submitted, the FDA may decide that the NDA does not satisfy the criteria for approval.
If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the NDA with a REMS to ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a medicine and to enable patients to have continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries, and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may also require one or more Phase 4 post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies. In addition, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could impact the timeline for regulatory approval or otherwise impact ongoing development programs.
In addition, the Pediatric Research Equity Act (PREA), requires a sponsor to conduct pediatric clinical trials for most drugs, for a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration. Under PREA, original NDAs and supplements must contain a pediatric assessment unless the sponsor has received a deferral or waiver. The required assessment must evaluate the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The sponsor or FDA may request a deferral of pediatric clinical trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that the drug is ready for approval for use in adults before pediatric clinical trials are complete or that additional safety or effectiveness data needs to be collected before the pediatric clinical trials begin. The FDA must send a non-compliance letter to any sponsor that fails to submit the required assessment, keep a deferral current or fails to submit a request for approval of a pediatric formulation.
Expedited Development and Review Programs
The FDA has a fast track designation program that is intended to expedite or facilitate the process for reviewing new drug products that meet certain criteria. Specifically, new drugs are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. With regard to a fast track product, the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.
Any product submitted to the FDA for approval, including a product with a fast track designation, may also be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. A product is eligible for priority review if it has the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug designated for priority review in an effort to facilitate the review. The FDA endeavors to review applications with priority review designations within six months of the filing date as compared to ten months for review of new molecular entity NDAs under its current PDUFA review goals.
38
In addition, a product may be eligible for accelerated approval. Drug products intended to treat serious or life-threatening diseases or conditions may be eligible for accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials. In addition, the FDA currently requires pre-approval of promotional materials as a condition for accelerated approval, which could adversely impact the timing of the commercial launch of the product.
The Food and Drug Administration Safety and Innovation Act established a category of drugs referred to as “breakthrough therapies” that may be eligible to receive breakthrough therapy designation. A sponsor may seek FDA designation of a product candidate as a “breakthrough therapy” if the product is intended, alone or in combination with one or more other products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance. The breakthrough therapy designation is a distinct status from both accelerated approval and priority review, which can also be granted to the same drug if relevant criteria are met. If a product is designated as breakthrough therapy, the FDA will work to expedite the development and review of such drug.
Fast track designation, breakthrough therapy designation, priority review, and accelerated approval do not change the standards for approval, but may expedite the development or approval process. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. We may explore some of these opportunities for our product candidates as appropriate.
Post-approval Requirements
Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual program fees for any marketed products. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.
The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:
•restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
•fines, warning letters, or untitled letters;
•clinical holds on clinical studies;
39
•refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product license approvals;
•product seizure or detention, or refusal to permit the import or export of products;
•consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;
•mandated modification of promotional materials and labeling and the issuance of corrective information;
•the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or
•injunctions or the imposition of civil or criminal penalties.
The FDA closely regulates the marketing, labeling, advertising and promotion of drug products. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may prescribe, in their independent professional medical judgment, legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined companies from engaging in off-label promotion. The FDA and other regulatory agencies have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. However, companies may share truthful and not misleading information that is otherwise consistent with a product’s FDA-approved labelling.
Marketing Exclusivity
Market exclusivity provisions authorized under the FDCA can delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or even accept for review an abbreviated new drug application (ANDA), or an NDA submitted under Section 505(b)(2) (505(b)(2) NDA), submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovative drug or for another indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.
The FDCA alternatively provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to any preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.
40
Pediatric exclusivity is another type of marketing exclusivity available in the United States. Pediatric exclusivity provides for an additional six months of marketing exclusivity attached to another period of exclusivity if a sponsor conducts clinical trials in children in response to a written request from the FDA. The issuance of a written request does not require the sponsor to undertake the described clinical trials. In addition, orphan drug exclusivity, as described above, may offer a seven-year period of marketing exclusivity, except in certain circumstances.
Other Healthcare Laws
Pharmaceutical and medical device manufacturers are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business. Such laws may constrain the business or financial arrangements and relationships through which we research, as well as, sell, market and distribute any products for which we obtain marketing approval and include, without limitation:
•the federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act;
•the federal false claims laws, including the civil False Claims Act, which can be enforced by private citizens through civil whistleblower or qui tam actions, and civil monetary penalties laws prohibit individuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
•the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) prohibits, among other things, executing or attempting to execute a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;
•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, which impose obligations on covered entities, including certain healthcare providers, health plans, and healthcare clearinghouses, and their respective business associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity as well as their covered subcontractors, with respect to safeguarding the privacy, security and transmission of individually identifiable health information; and
•the federal Physician Payments Sunshine Act requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to annually report to CMS information regarding payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as physician assistants and nurse practitioners) and teaching hospitals, as well as information regarding ownership and investment interests held by physicians and their immediate family members. The information reported is publicly available on a searchable website, with disclosure required annually.
41
State and local healthcare laws and regulations may also restrict business practices in the pharmaceutical industry, such as state anti-kickback and false claims laws, which may be broader in scope than their federal counterparts and apply to business practices, including but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, or by patients themselves; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information; state and local laws which require tracking gifts and other remuneration and items of value provided to physicians, other healthcare providers and entities or that require the registration of pharmaceutical sales representatives; and state and local laws that require the registration of pharmaceutical sales representatives; and state and local laws governing the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.
Violation of any of such laws or any other governmental regulations that apply may result in penalties, including, without limitation, significant administrative, civil and criminal penalties, damages, fines, imprisonment, additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, the curtailment or restructuring of operations, exclusion from participation in governmental healthcare programs and imprisonment.
Coverage and Reimbursement
Sales of any pharmaceutical product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Significant uncertainty exists as to the coverage and reimbursement status of any newly approved product. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. One third-party payor’s decision to cover a particular product does not ensure that other payors will also provide coverage for the product. As a result, the coverage determination process can require manufactures to provide scientific and clinical support for the use of a product to each payor separately and can be a time-consuming process, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization. In addition, companion diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for their companion pharmaceutical or biological products. Similar challenges to obtaining coverage and reimbursement, applicable to pharmaceutical or biological products, will apply to companion diagnostics.
In addition, third-party payors are increasingly reducing reimbursements for pharmaceutical products and services. The U.S. government and state legislatures have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Third-party payors are more and more challenging the prices charged, examining the medical necessity and reviewing the cost effectiveness of pharmaceutical products, in addition to questioning their safety and efficacy. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Coverage policies and third-party payor reimbursement rates may change at any time. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product.
42
In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. Pharmaceutical products may face competition from lower-priced products in foreign countries that have placed price controls on pharmaceutical products and may also compete with imported foreign products. Furthermore, there is no assurance that a product will be considered medically reasonable and necessary for a specific indication, will be considered cost-effective by third-party payors, that an adequate level of reimbursement will be established even if coverage is available or that the third-party payors’ reimbursement policies will not adversely affect the ability for manufacturers to sell products profitably.
Healthcare Reform
In the United States and certain foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system. In March 2010, the ACA was signed into law, which substantially changed the way healthcare is financed by both governmental and private insurers in the United States. By way of example, the ACA increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 23.1%; required collection of rebates for drugs paid by Medicaid managed care organizations; imposed a non-deductible annual fee on pharmaceutical manufacturers or importers who sell certain “branded prescription drugs” to specified federal government programs, implemented a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted, or injected; expanded eligibility criteria for Medicaid programs; creates a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.
Since its enactment, there have been executive, judicial and Congressional challenges to certain aspects of the ACA. For example, in January 2017, President Trump signed several Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress considered legislation to repeal or repeal and replace all or part of the ACA. For example, legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act, or Tax Act, eliminated the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” In addition, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminated the health insurer tax. On June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our business.
Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions of Medicare payments to providers of 2% per fiscal year and reduced payments to several types of Medicare providers, which will remain in effect through 2031 absent additional congressional action, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic. Under current legislation the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. Additionally, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a
43
drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024.
Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries, presidential executive orders, and proposed and enacted legislation designed, among other things, to bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for pharmaceutical products. At the federal level, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, President Trump announced four executive orders related to prescription drug pricing that attempt to implement several of the administration’s proposals. The FDA also released a final rule and guidance implementing a portion of the importation executive order providing pathways for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, the U.S. Department of Health and Human Services (HHS) finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022, to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed pending review by the Biden administration until January 1, 2023. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. As a result of litigation challenging the Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded the Most Favored Nation model interim final rule. In July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, individual states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures and, in some cases, mechanisms to encourage importation from other countries and bulk purchasing. Furthermore, there has been increased interest by third party payors and governmental authorities in reference pricing systems and publication of discounts and list prices. Further, it is possible that additional governmental action is taken in response to the COVID-19 pandemic.
FDA Approval and Regulation of Companion Diagnostics
If safe and effective use of a therapeutic depends on an in vitro diagnostic, then the FDA generally will require approval or clearance of that diagnostic, known as a companion diagnostic, at the same time that the FDA approves the therapeutic product. In August 2014, the FDA issued final guidance clarifying the requirements that apply to approval of therapeutic products and in vitro companion diagnostics. According to the guidance, if FDA determines that a companion diagnostic device is essential to the safe and effective use of a novel therapeutic product or indication, FDA generally will not approve the therapeutic product or new therapeutic product indication if the companion diagnostic device is not approved or cleared for that indication. Approval or clearance of the companion diagnostic device will ensure that the device has been adequately evaluated and has adequate performance characteristics in the intended population. The review of in vitro companion diagnostics in conjunction with the review of our therapeutic treatments for cancer will, therefore, likely involve coordination of review by the FDA’s Center for Drug Evaluation and Research and the FDA’s Center for Devices and Radiological Health Office of In Vitro Diagnostics and Radiological Health.
44
Under the FDCA, in vitro diagnostics, including companion diagnostics, are regulated as medical devices. In the United States, the FDCA and its implementing regulations, and other federal and state statutes and regulations govern, among other things, medical device design and development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, sales and distribution, export and import, and post-market surveillance. Unless an exemption applies, diagnostic tests require marketing clearance or approval from the FDA prior to commercial distribution. The two primary types of FDA marketing authorization applicable to a medical device are premarket notification, also called 510(k) clearance, and premarket approval (PMA approval).
The PMA process, including the gathering of clinical and preclinical data and the submission to and review by the FDA, can take several years or longer. It involves a rigorous premarket review during which the applicant must prepare and provide the FDA with reasonable assurance of the device’s safety and effectiveness and information about the device and its components regarding, among other things, device design, manufacturing and labeling. PMA applications are subject to an application fee. In addition, PMAs for certain devices must generally include the results from extensive preclinical and adequate and well-controlled clinical trials to establish the safety and effectiveness of the device for each indication for which FDA approval is sought. In particular, for a diagnostic, a PMA application typically requires data regarding analytical and clinical validation studies. As part of the PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality System Regulation (QSR), which imposes elaborate testing, control, documentation and other quality assurance requirements.
PMA approval is not guaranteed, and the FDA may ultimately respond to a PMA submission with a not approvable determination based on deficiencies in the application and require additional clinical trial or other data that may be expensive and time-consuming to generate and that can substantially delay approval. If the FDA’s evaluation of the PMA application is favorable, the FDA typically issues an approvable letter requiring the applicant’s agreement to specific conditions, such as changes in labeling, or specific additional information, such as submission of final labeling, in order to secure final approval of the PMA. If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. A not approvable letter will outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. The FDA may also determine that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the trials are conducted and then the data submitted in an amendment to the PMA. If the FDA concludes that the applicable criteria have been met, the FDA will issue a PMA for the approved indications, which can be more limited than those originally sought by the applicant. The PMA can include post-approval conditions that the FDA believes necessary to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution. Once granted, PMA approval may be withdrawn by the FDA if compliance with post approval requirements, conditions of approval or other regulatory standards are not maintained or problems are identified following initial marketing.
After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may be marketed only for the uses and indications for which they are cleared or approved. Device manufacturers must also establish registration and device listings with the FDA. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the QSR, which cover the methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by the FDA. The FDA also may inspect foreign facilities that export products to the United States.
Legal Proceedings
From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not currently a party to any material legal proceedings. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

Human Capital Resources
As of January 1, 2022, we had 96 full-time employees. Of these employees, 48 hold Ph.D. or M.D. degrees, and 72 are engaged in research, development and technical operations. Substantially all of our employees work out of our offices in either San Mateo, California, or Cambridge, Massachusetts. We have three dedicated, full-time employee equivalents responsible for executing our human capital management strategy and overseeing all aspects of our human resources processes in place to support our employees. Our employees are not represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good. Since our founding, we have had relatively low turnover of employees, which we attribute to our shared mission of transforming the lives of those affected by cancer.
Our employees are essential to our success. We have been purposeful in our efforts to hire, develop and retain diverse talent as well as create an inclusive culture. We are investing in building and maintaining a work environment that prioritizes the health, safety and wellness of our team, and where our employees are inspired to deliver their best every day. All employees are responsible for upholding the Kronos Bio Code of Conduct, which forms the foundation of our policies and practices. As a newly public company, we continue to expand our systems to track key human capital metrics such as demographics, diversity, compensation and benefits, and engagement.
Diversity, Equity and Inclusion
We are committed to creating and maintaining a diverse, inclusive and safe work environment. Our employees bring diversity to our workplace across many critical categories, and we believe our company is stronger as a result of their variety of experiences and backgrounds. For example, more than half of our employees and more than one-third of our senior leaders are female. As we grow and mature, we look forward to establishing programs that bring in speakers on specific topics, assemble resources for employees on diversity and inclusion, provide support for our female and underrepresented employees to help advance their careers, all while continuing to focus on hiring, developing and promoting diverse talent at all levels of the company.

ITEM 1A. RISK FACTORS
RISK FACTORS
We have identified the following material factors that make an investment in our common stock speculative or risky. You should carefully consider the risks described below, as well as the other information in this Annual Report on Form 10-K, including our financial statements and the related notes included elsewhere in this Annual Report on Form 10-K and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before making investment decisions regarding our common stock. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the market price of our common stock could decline and you may lose all or part of your investment. The risks described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations.
Risks Related to Our Financial Condition and Capital Requirements
We have incurred significant net losses since inception, and we expect to incur significant losses over the next several years and may not be able to achieve or sustain revenues or profitability in the future.
Investment in biopharmaceutical product development is a highly speculative undertaking and entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, gain regulatory approval and become commercially viable. We have no products approved for commercial sale and have not generated any revenue from product sales to date, and we will continue to incur significant research and development and other expenses related to our ongoing operations. We have financed our operations primarily through our IPO and, before that, private placements of our convertible preferred stock and convertible notes.
We have incurred significant net losses in each period since we commenced operations in June 2017. For the years ended December 31, 2021, 2020, and 2019, we reported net losses of $151.1 million, $88.4 million, and $16.1 million, respectively. As of December 31, 2021, we had an accumulated deficit of $263.0 million. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase substantially if and as we:
•conduct preclinical studies and clinical trials for our current and future product candidates;
•continue our research and development efforts, submit INDs and clinically develop our product candidates;
•seek marketing approvals for any product candidates that successfully complete clinical trials;
•experience any delays or encounter any issues with any of the above, including but not limited to failed studies, negative or mixed clinical trial results, safety issues or other regulatory challenges, the risk of which in each case may be exacerbated by the ongoing COVID-19 pandemic;
•establish a sales, marketing and distribution infrastructure and establish manufacturing capabilities, whether alone or with third parties, to commercialize product candidates for which we may obtain regulatory approval, if any;
•obtain, expand, maintain, enforce and protect our intellectual property portfolio;
•hire additional clinical, regulatory and scientific personnel; and
•operate as a public company.
48
Because of the numerous risks and uncertainties associated with biopharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses we will incur or when, if ever, we will be able to achieve profitability. Even if we succeed in commercializing one or more of our product candidates, we will continue to incur substantial research and development and other expenditures to develop, seek regulatory approval for and potentially market our product candidates. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability, if ever, to generate revenue from our product candidates. Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity and working capital.
We have not generated any revenue from our product candidates and may never be profitable.
Our ability to become profitable depends upon our ability to generate revenue. To date, we have not generated any revenue from any of our product candidates. We do not expect to generate significant revenue unless or until we successfully complete clinical development and obtain regulatory approval of, and then successfully commercialize, our product candidates. Entospletinib and lanraplenib, which we acquired from Gilead in July 2020, and KB-0742 are our only product candidates in the clinical stage of development. In addition, all of our product candidates will require additional clinical development, regulatory review and approval, substantial investment, access to sufficient commercial manufacturing capacity and significant marketing efforts before we can generate any revenue from product sales. Our ability to generate revenue from our product candidates depends on a number of factors, including, but not limited to:
•timely completion of our preclinical studies and ongoing and planned clinical trials, which may be significantly slower or cost more than we currently anticipate and will depend substantially upon the performance of third-party contractors;
•our ability to complete IND-enabling studies and successfully submit and receive authorizations to proceed under INDs or comparable applications;
•whether we are required by the FDA or similar foreign regulatory authorities to conduct additional clinical trials or other studies beyond those planned to support the potential approval and commercialization of our product candidates or of any future product candidates;
•our ability to demonstrate to the satisfaction of the FDA and similar foreign regulatory authorities the safety, potency, purity, efficacy and acceptable risk-benefit profile of our product candidates or any future product candidates and such regulatory authorities’ acceptance of our biomarker-driven development strategy (i.e., our pursuit of approval based on a biomarker rather than a specific cancer indication);
•the prevalence, duration and severity of potential side effects or other safety issues experienced with our product candidates or future product candidates, if any;
•the timely receipt of necessary marketing approvals from the FDA and similar foreign regulatory authorities;
•the willingness of physicians, operators of clinics and patients to utilize or adopt any of our product candidates or future product candidates over or to use in combination with alternative or more established therapies, such as intensive chemotherapy and HMAs, to treat AML and MYC-amplified solid tumors and other transcriptionally addicted cancers;
•the actual and perceived availability, cost, risk profile and side effects and efficacy of our product candidates, if approved, relative to existing and future alternative cancer therapies and competitive product candidates and technologies;
•our ability and the ability of third parties with whom we contract to manufacture adequate clinical and commercial supplies of our product candidates or any future product candidates, remain in good standing with regulatory authorities and develop, validate and maintain commercially viable manufacturing processes that are compliant with current good manufacturing practices (cGMP);
49
•our ability to successfully develop a commercial strategy and thereafter commercialize our product candidates or any future product candidates in the United States and internationally, if approved for marketing, reimbursement, sale and distribution in such countries and territories, whether alone or in collaboration with others;
•patient demand for our product candidates and any future product candidates, if approved; and
•our ability to establish and enforce intellectual property rights in and to our product candidates or any future product candidates.
Many of the factors listed above are beyond our control and could cause us to experience significant delays or prevent us from obtaining regulatory approvals or commercializing any of our product candidates. Even if we are able to commercialize our product candidates, we may not achieve profitability soon after generating product sales, if ever. If we are unable to generate sufficient revenue through the sale of our product candidates or any future product candidates, we may be unable to continue operations without continued funding.
We will need substantial additional funding. If we are unable to raise capital when needed, we would be compelled to delay, reduce or eliminate our product development programs or commercialization efforts.
We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we progress our ongoing clinical trials and commence our planned clinical trials and any other future clinical trials, and continue our discovery and preclinical development activities to identify new product candidates, and seek marketing approval for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations, and we may need to raise additional funding sooner than expected if we choose to expand more rapidly than we presently anticipate. We cannot be certain that additional funding will be available on acceptable terms, or at all. Further, the duration and severity of the COVID-19 pandemic and its impact on the economy and financial markets in general could adversely affect our ability to raise additional capital. Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships and alliances or marketing, distribution or licensing arrangements with third parties. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our discovery and preclinical development programs or any future commercialization efforts.
We had cash, cash equivalents, and investments of $339.5 million as of December 31, 2021. We believe that, based upon our current operating plan, our existing capital resources will enable us to fund our planned operating expenses and capital expenditure requirements into the second half of 2024, including through the readout of the primary endpoint of our registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in AML patients with NPM1 mutations, and the completion of our Phase 1/2 clinical trial of KB-0742 for the treatment of advanced solid tumors. However, we have based this estimate on our current development plans and assumptions that may prove to be wrong. Additionally, changing circumstances may cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control, including as a result of the COVID-19 pandemic. In any event, our future capital requirements will depend on many factors, including:
•the scope, progress, results and costs of our ongoing registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy for the treatment of AML patients with NPM1 mutations;
•the scope, progress, results and costs of our ongoing Phase 1/2 clinical trial of KB-0742;
•the scope, progress, results and costs of our planned Phase 1b/2 clinical trial of lanraplenib;
•the scope, progress, results and costs of discovery, preclinical development and clinical trials for our other product candidates;
•the costs, timing and outcome of regulatory review of our product candidates and any required companion diagnostic;
•the extent to which we develop, in-license or acquire other pipeline product candidates or technologies;
50
•the costs of future commercialization activities, including product sales, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval;
•the costs associated with completing any post-marketing studies or trials required by the FDA or other regulatory authorities;
•revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive marketing approval;
•the costs of preparing, filing and prosecuting patent applications, obtaining, maintaining, enforcing and protecting our intellectual property rights and defending intellectual property-related claims; and
•to the extent we pursue strategic collaborations, including collaborations to commercialize any of our product candidates or any companion diagnostic collaborations, our ability to establish and maintain collaborations on favorable terms, if at all.
We will require additional capital to complete our planned clinical development programs for our current product candidates to obtain regulatory approval. Any additional capital-raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our current and future product candidates, if approved.
Risks Related to the Discovery and Development of our Product Candidates
We have a limited operating history and face significant challenges and will incur substantial expenses as we build our capabilities.
We were incorporated in June 2017 and acquired certain rights to entospletinib and lanraplenib and other orally bioavailable small molecule SYK inhibitors from Gilead in July 2020. We have a limited operating history and are subject to the risks inherent in a growing company, including, among other things, risks that we may not be able to hire sufficient qualified personnel and establish operating controls and procedures. We currently do not have complete in-house resources to enable our operations. As we continue to build our capabilities, we expect to encounter risks and uncertainties frequently experienced by growing companies in new and rapidly evolving fields, including the risks and uncertainties related to the evolving effects of the COVID-19 pandemic and those described herein. If we are unable to continue to build our capabilities, our operating and financial results could differ materially from our expectations, and our business could suffer.
We cannot be certain that our ongoing or planned clinical trials of our product candidates, including our ongoing Phase 1/2 clinical trial of KB-0742, our only internally generated product candidate, or our ongoing registrational Phase 3 clinical trial of entospletinib or our planned Phase 1b/2 clinical trial of lanraplenib will begin or be completed when we currently expect, or at all.
We may not realize the benefits of our asset acquisition from Gilead or any future acquisitions or strategic transactions.
In the third quarter of 2020, we completed the transfer from Gilead of a portfolio of selective, orally bioavailable small molecule SYK inhibitors, including entospletinib and lanraplenib, that we acquired from Gilead in July 2020, and it is possible that we will encounter challenges with integrating the data and technology, along with the related regulatory materials, related to these acquired product candidates into our business. In such event, our clinical development plans related to the acquired SYK product candidates, including our ongoing registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in AML patients with NPM1 mutations, our planned Phase 1b/2 clinical trial of lanraplenib in a genetically-defined subset of AML patients, or the associated or subsequent regulatory filings, could be delayed or otherwise adversely affected.
In addition, we may acquire other businesses, products or technologies as well as pursue joint ventures or investments in complementary businesses. The success of our SYK portfolio acquisition from Gilead, and any future acquisitions or strategic transactions depends on the risks and uncertainties involved including, but not limited to, the following:
•unanticipated liabilities related to acquired assets, companies or joint ventures;
51
•difficulties integrating acquired personnel, technologies and operations into our existing business;
•retention of key employees;
•diversion of management time and focus from operating our business to management of strategic alliances or joint ventures or acquisition integration challenges;
•increases in our expenses and reductions in our cash available for operations and other uses;
•disruption in our relationships with collaborators or suppliers as a result of such a transaction; and
•possible write-offs or impairment charges relating to acquired assets, businesses or joint ventures.
If any of these risks or uncertainties occur, we may not realize the anticipated benefit of any acquisition or strategic transaction. Additionally, foreign acquisitions and joint ventures are subject to additional risks, including those related to integration of operations across different cultures and languages, currency risks, potentially adverse tax consequences of overseas operations and the particular economic, political and regulatory risks associated with specific countries.
Future acquisitions or dispositions could also result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses or write-offs of goodwill, any of which could harm our financial condition.
Our discovery and development activities are focused on novel cancer therapeutics for patients with genetically-defined cancers and it is difficult to predict the time and cost of product candidate development and likelihood of obtaining regulatory approval.
The discovery and development of novel cancer therapeutics by targeting dysregulated transcription using a biomarker-driven precision medicine strategy is an emerging field, and the scientific discoveries that form the basis for our efforts to discover and develop product candidates are relatively new. The scientific evidence to support the feasibility of developing product candidates based on these discoveries is both preliminary and limited. Although we believe, based on our preclinical work, and the data for entospletinib and lanraplenib generated in clinical trials conducted by Gilead, the TRNs targeted by our programs drive oncogenic activity, future clinical results may not confirm this hypothesis or may only confirm it for certain mutations or certain tumor types. The patient populations for our product candidates are limited to those with cancers that exhibit specific target mutations that we believe serve as a genomic biomarker of transcription factor dysregulation, and may not be completely defined but are substantially smaller than the general treated cancer population, and we will need to screen and identify those patients who have the targeted mutations. Successful identification of patients is dependent on several factors, including achieving certainty as to how specific genetic alterations respond to our product candidates and developing or otherwise obtaining access to satisfactory companion diagnostics to identify such genetic alterations. Furthermore, even if we are successful in identifying patients, we cannot be certain that the resulting patient populations for each mutation will be large enough to allow us to successfully obtain approval for each mutation type and commercialize our products and achieve profitability. In any event, we do not know if our approach of treating patients with genetically defined cancers will be successful, and if our approach is unsuccessful, our business will suffer and you may lose all or part of your investment.
In addition, we are pursuing a biomarker-driven development strategy (i.e., pursuing regulatory approval based on efficacy of our product candidates in a biomarker-defined subset of patients with a specific cancer indication, rather than all such patients who suffer from a specific cancer indication). There is currently a limited number of approved biomarker-specific therapies. We may not receive approval for a biomarker-specific indication or may be delayed in receiving biomarker-specific approval.
52
We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of entospletinib or our other product candidates.
We are unable to predict when or if our products candidates will prove effective or safe in humans or will obtain marketing approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim or preliminary results of a clinical trial do not necessarily predict final results. It is not uncommon to observe results in clinical trials that are unexpected based on preclinical studies and early clinical trials, and many product candidates fail in clinical trials despite very promising early results. Moreover, preclinical and clinical data may be susceptible to varying interpretations and analyses. A number of companies in the biopharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies. In addition, there can be no assurance that the encouraging safety and efficacy data observed in the Phase 1b/2 clinical trial of entospletinib in 148 AML patients, which was conducted by Gilead, will be indicative of the safety or efficacy results that we will observe in our ongoing registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in AML patients with NPM1 mutations.
We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to obtain marketing approval or commercialize our product candidates, including:
•regulators or institutional review boards (IRBs)/ethics committees (ECs) may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;
•we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts with prospective trial sites;
•clinical trials for our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials, delay clinical trials or abandon product development programs;
•the number of patients required for clinical trials for our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate, participants may drop out of these clinical trials at a higher rate than we anticipate or the duration of these clinical trials may be longer than we anticipate;
•competition for clinical trial participants from investigational and approved therapies may make it more difficult to enroll patients in our clinical trials;
•third-party collaborators may undergo a change of control, thus delaying progression of a clinical trial;
•we or potential future third-party collaborators may fail to obtain the clearance or approval of any required companion diagnostic on a timely basis, or at all;
•our third-party contractors, including those developing companion diagnostic tests, may fail to meet their contractual obligations to us in a timely manner, or at all, or may fail to comply with regulatory requirements;
•we may have to suspend or terminate clinical trials for our product candidates for various reasons, including a finding that the participants are being exposed to unacceptable health risks;
•our product candidates may have undesirable or unexpected side effects or other unexpected characteristics, causing us or our investigators, regulators or IRBs/ECs to suspend or terminate the trials;
•the cost of clinical trials for our product candidates may be greater than we anticipate;
53
•the supply or quality of our product candidates or other materials necessary to conduct clinical trials for our product candidates may be insufficient or inadequate and result in delays or suspension of our clinical trials; and
•we or potential future third-party collaborators may fail to receive regulatory approval of a companion diagnostic for one or more of our product candidates, or for use with a marketed product.
Our product development costs will increase if we experience delays in preclinical studies or clinical trials or in obtaining marketing approvals. We do not know whether any of our planned preclinical studies or clinical trials will begin on a timely basis or at all, will need to be restructured or will be completed on schedule, or at all.
Significant preclinical or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.
Any delays in the commencement or completion, or termination or suspension, of our planned or future clinical trials could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.
Before we can initiate clinical trials of a product candidate in any indication, we must submit the results of preclinical studies to the FDA along with other information, including information about the product candidate’s chemistry, manufacturing and controls and our proposed clinical trial protocol, as part of an IND or similar regulatory submission under which we must receive authorization to proceed with clinical development.
Before obtaining marketing approval from the FDA of entospletinib or of any other product candidate in any indication, we must conduct extensive clinical studies to demonstrate safety and efficacy. Clinical testing is expensive, time consuming and uncertain as to outcome. In addition, we expect to rely in part on preclinical, clinical and quality data generated by our CROs and other third parties for regulatory submissions for our product candidates. While we have or will have agreements governing these third parties’ services, we have limited influence over their actual performance. If these third parties do not make data available to us, or, if applicable, make regulatory submissions in a timely manner, in each case pursuant to our agreements with them, our development programs may be significantly delayed and we may need to conduct additional studies or collect additional data independently. In either case, our development costs would increase. We are required to submit an IND to the FDA, which must become effective prior to initiating any clinical trials in the United States, for our preclinical product candidates.
The FDA may require us to conduct additional preclinical studies for any product candidate before it allows us to initiate clinical trials under any IND, which may lead to additional delays and increase the costs of our preclinical development programs.
Any delays in the commencement or completion of our planned or future clinical trials could significantly affect our product development costs. We do not know whether our planned trials will begin on time or be completed on schedule, if at all. The commencement and completion of clinical trials can be delayed for a number of reasons, including delays related to:
•obtaining FDA or foreign regulatory authority authorization to commence a clinical trial or reaching a consensus with the FDA or a foreign regulatory authority on clinical trial design;
•failing to obtain regulatory clearance or approval of companion diagnostics we may use to identify patients for enrollment in or test the possible effects of our product candidates in patients enrolled in our clinical trials;
•any failure or delay in reaching an agreement with CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
•obtaining approval from one or more IRBs/ECs;
•IRBs/ECs refusing to approve, suspending or terminating the trial at an investigational site, precluding enrollment of additional subjects, or withdrawing their approval of the trial;
54
•changes to clinical trial protocol;
•clinical sites deviating from trial protocol or dropping out of a trial;
•failing to manufacture or obtain sufficient quantities of product candidate or, if applicable, combination therapies for use in clinical trials;
•patients failing to enroll or remain in our trial at the rate we expect, or failing to return for post-treatment follow-up, including patients failing to remain in our trials due to movement restrictions, health reasons or otherwise resulting from the evolving effects of the COVID-19 pandemic;
•patients choosing an alternative treatment, or participating in competing clinical trials;
•lack of adequate funding to continue the clinical trial;
•patients experiencing severe or unexpected drug-related adverse effects;
•occurrence of serious adverse events in trials of the same class of agents conducted by other companies;
•selecting or being required to use clinical end points that require prolonged periods of clinical observation or analysis of the resulting data;
•a facility manufacturing our product candidates or companion diagnostics or any of their components being ordered by the FDA or applicable foreign regulatory authorities to temporarily or permanently shut down due to violations of cGMP regulations or other applicable requirements, or infections or cross-contaminations of product candidates in the manufacturing process;
•interruptions to operations of clinical sites, manufacturers, suppliers, or other vendors from a health epidemic or pandemic, such as the COVID-19 pandemic;
•any changes to our manufacturing process that may be necessary or desired;
•third-party clinical investigators losing the licenses or permits necessary to perform our clinical trials, not performing our clinical trials on our anticipated schedule or consistent with the clinical trial protocol, good clinical practices (GCP) or other regulatory requirements;
•us, or our third-party contractors not performing data collection or analysis in a timely or accurate manner or improperly disclosing data prematurely or otherwise in violation of a clinical trial protocol;
•third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or all of the data produced by such contractors in support of our marketing applications; or
•disruptions caused by the COVID-19 pandemic, which may increase the likelihood that we encounter difficulties or delays in initiating, enrolling, conducting or completing our ongoing or planned clinical trials.
55
In addition, our proposal for new or emerging biomarker surrogate endpoints may result in data that is not accepted by certain regulatory bodies or industry professionals, or if such endpoints are later found to be insufficient to establish clinical efficacy, may require us to change the design of our clinical trials. With respect to our ongoing registrational trial of entospletinib in patients with NPM1 mutated AML, following our discussions with FDA as part of our End-of-Phase 2 meeting, we are using MRD-negative CR as the primary endpoint in support of accelerated approval. MRD has only recently emerged as a surrogate endpoint for progression free survival in hematological malignancies, and while regulatory approvals on the basis of MRD status have been granted in acute lymphocytic leukemia and chronic lymphocytic leukemia (CLL), to date there have not been any regulatory approvals on the basis of MRD status in AML. We are proceeding with our randomized, double-blinded, placebo-controlled registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in approximately 180 newly diagnosed NPM1-mutated AML patients. We intend to work with a third-party diagnostic partner, who will complete the validation of the assay necessary to meet regulatory requirements for a companion diagnostic in parallel with the conduct of the clinical trial. Patients will be randomized to receive standard of care intensive chemotherapy in combination with twice-daily entospletinib or a placebo. MRD will be assessed in patients who achieve a CR after two cycles of chemotherapy. Patients who achieve CR, CR with partial hematological recovery (CRh) or CR without count recovery (CRi) may go on to receive consolidation therapy and undergo follow-up assessment for event-free, relapse-free and overall survival. MRD-negative CR in the intent-to-treat population is the proposed primary endpoint for accelerated approval. This planned trial may not enable an expeditious path to regulatory approval in newly diagnosed AML patients with NPM1 mutations and may not be accepted by the FDA or otherwise be sufficient to obtain regulatory approval, which could result in a longer time to potential commercialization of entospletinib in the United States, if approved and commercialized at all, and could increase the costs of development and could harm our competitive position in the marketplace. In addition, even if we obtain accelerated approval, failure of the industry to adopt MRD-negative CR rate as a valid or meaningful endpoint for an AML therapeutic may adversely impact our commercial prospects as a result of our clinical trial results being discounted or disregarded by industry professionals.
We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs/ECs of the institutions in which such trials are being conducted, by a Data Safety Monitoring Board for such trial or by the FDA or foreign regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a pharmaceutical, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. In addition, changes in regulatory requirements and policies may occur, and we may need to amend clinical trial protocols to comply with these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs/ECs for reexamination, which may impact the costs, timing or successful completion of a clinical trial.
Certain of our current or future scientific advisors or consultants who receive compensation from us may become investigators for our future clinical trials. Under certain circumstances, we may be required to report some of these relationships to the FDA. Although we expect any such relationships to be within the FDA’s guidelines, the FDA may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected the interpretation of the study. The FDA may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of marketing approval of entospletinib or our other product candidates. If we experience delays in the completion of, or termination of, any clinical trial, the commercial prospects of such product candidate will be harmed, and our ability to generate product revenues will be delayed. Moreover, any delays in completing our clinical trials will increase our costs, slow down our development and approval process and jeopardize our ability to commence product sales and generate revenues which may harm our business, financial condition, results of operations and prospects significantly.
56
If we experience delays or difficulties in enrolling patients in our ongoing or planned clinical trials, regulatory approval could be delayed or we could fail to obtain regulatory approval.
We may not be able to initiate or continue our ongoing or planned clinical trials for our product candidates if we are unable to identify and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA. In addition, some of our competitors may have ongoing clinical trials for product candidates that would treat the same or a similar patient population as we plan to treat with our product candidates in clinical trials, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates.
We have initiated a Phase 1/2 clinical trial of KB-0742 in cancer patients to evaluate its safety, PK and PD across multiple dose levels. Following identification of a recommended Phase 2 clinical trial dose and schedule, we intend to enroll expansion cohorts in one or more biomarker-defined patient populations with transcriptionally addicted cancers, beginning with MYC-amplified solid tumors independent of histology. However, if the safety, PK or PD data from the first stage of the clinical trial suggest our initial doses are suboptimal, this could delay or preclude initiation of the expansion cohorts. We may also seek to enroll an additional cohort of soft tissue sarcoma patients with transcription factor fusions and patients with chordoma, an incurable solid tumor addicted to the brachyury transcription factor, in order to further demonstrate proof of concept for KB-0742. While we believe it is feasible to enroll such patients at major academic centers, patients with these tumor types are relatively rare, and we may be unable to enroll or maintain a sufficient number of these patients in any such additional cohort, which could adversely affect our development and registration strategy for KB-0742.
We have also initiated a Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy, and plan to enroll approximately 180 newly diagnosed NPM1-mutated AML patients, though we may be unable to enroll or maintain these patients within our anticipated timelines.
Patient enrollment is also affected by other factors, including:
•severity of the disease under investigation;
•our ability to recruit clinical trial investigators of appropriate competencies and experience;
•the incidence and prevalence of our target indications;
•clinicians’ and patients’ awareness of, and perceptions as to the potential advantages and risks of our product candidates in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating;
•invasive procedures required to enroll patients and to obtain evidence of the product candidate’s performance during the clinical trial;
•availability and efficacy of approved medications for the disease under investigation;
•eligibility criteria defined in the protocol for the trial in question;
•the size of the patient population required for analysis of the trial’s primary endpoints;
•efforts to facilitate timely enrollment in clinical trials;
•whether we are subject to a partial or full clinical hold on any of our clinical trials;
•reluctance of physicians to encourage patient participation in clinical trials;
•the ability to monitor patients adequately during and after treatment;
•our ability to obtain and maintain patient consents;
•proximity and availability of clinical trial sites for prospective patients; and
•our ability to timely activate clinical trial sites during the ongoing COVID-19 pandemic and other delays and complications resulting from the evolving effects of the COVID-19 pandemic.
57
Enrollment in our trials has been adversely impacted by the COVID-19 pandemic on a rolling basis as healthcare facilities and patients have experienced periodic delays in visits and scheduling that adversely impacts enrollment. Our inability to enroll the required number of patients for our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs, which would cause the value of our company to decline and limit our ability to obtain additional financing.
If adverse side effects or unexpected characteristics are identified during the development of our product candidates, we may need to abandon or limit the development of a product candidate.
As is the case with pharmaceuticals generally, side effects and adverse events (AEs) associated with entospletinib have been observed. In entospletinib’s first clinical trial in healthy volunteers and subjects with rheumatoid arthritis (RA), the most frequently reported AEs were headache, nausea and constipation without any clear relationship to dose level. Mildly increased liver enzymes were observed in some healthy subjects and patients with RA. In a clinical trial of entospletinib in more than 700 patients with hematologic malignancies, predominantly with B cell malignancies such as CLL, the most frequently reported treatment-related AEs, with an incidence greater than 10% in CLL patients, were fatigue, nausea, diarrhea, headache, decreased appetite and fever. AEs of Grade 3 or greater in at least 5% of patients included neutropenia, elevated liver enzymes and electrolyte abnormalities. Entospletinib has also been tested in a Phase 1b/2 clinical trial in 148 AML patients. Early entospletinib safety studies were conducted in relapsed patients as monotherapy and in combination with intensive chemotherapy and in newly diagnosed elderly patients in combination with HMAs such as azacytidine or decitabine. Aside from the AEs typical of the disease and intensive chemotherapy, such as cytopenias and fever, the main AEs attributable to entospletinib included diarrhea, nausea, and febrile neutropenia. Results of our ongoing or planned clinical trials, including those for entospletinib, lanraplenib and KB-0742, could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Undesirable side effects caused by our product candidates could result in the delay, suspension or termination of clinical trials by us or the FDA or foreign regulatory authorities for a number of reasons. Additionally, due to the high mortality rates of the cancers for which we are initially pursuing development of entospletinib, lanraplenib and KB-0742, a significant percentage of patients in these clinical trials may die during a trial, which could impact development of these product candidates. If we elect or are required to delay, suspend or terminate any clinical trial, the commercial prospects of our product candidates will be harmed and our ability to generate product revenues from this product candidate will be delayed or eliminated. Serious adverse events observed in clinical trials could hinder or prevent market acceptance of our product candidates. Any of these occurrences may harm our business, prospects, financial condition and results of operations significantly.
Moreover, if our product candidates are associated with undesirable side effects in clinical trials or have characteristics that are unexpected, we may elect to abandon or limit their development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective, which may limit the commercial expectations for our product candidates, if approved. We may also be required to modify our study plans based on findings in our clinical trials. Many drugs that initially showed promise in early stage testing have later been found to cause side effects that prevented further development. In addition, regulatory authorities may draw different conclusions or require additional testing to confirm these determinations.
It is possible that as we test our product candidates in larger, longer and more extensive clinical trials, including with different dosing regimens, or as the use of our product candidates becomes more widespread following any regulatory approval, illnesses, injuries, discomforts and other adverse events that were observed in earlier trials, as well as conditions that did not occur or went undetected in previous trials, will be reported by patients. If such side effects become known later in development or upon approval, if any, such findings may harm our business, financial condition, results of operations and prospects significantly.
In addition, if any of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by treatment with such drug, a number of potentially significant negative consequences could result, including:
•regulatory authorities may withdraw or limit their approval of the product;
•we may be required to recall a product or we may voluntarily remove it from the marketplace;
58
•we may be required to change the way the product is administered to patients or conduct additional clinical trials;
•regulatory authorities may require additional warnings on the label, such as a “black box” warning or a contraindication, or issue safety alerts, Dear Healthcare Provider letters, press releases or other communications containing warnings or other safety information about the product;
•we may be required to implement a Risk Evaluation and Mitigation Strategy (REMS) or create a medication guide outlining the risks of such side effects for distribution to patients;
•additional restrictions may be imposed on the marketing or promotion of the particular product or the manufacturing processes for the product or any component thereof;
•we could be sued and held liable for harm caused to patients;
•the drug could become less competitive; and
•our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of our product candidates, if approved, and could significantly harm our business, financial condition, results of operations and prospects.
Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available, and are subject to audit and verification procedures that could result in material changes in the final data.
From time to time in the future, we may publicly disclose preliminary, interim or topline data from our ongoing or planned clinical trials. These updates are typically based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial or following the completion of such clinical trial or stage of such clinical trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, topline or preliminary results that we may report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Interim, topline and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, such data should be viewed with caution until the final data are available. In addition, we may report interim analyses of only certain endpoints rather than all endpoints. Interim, topline, or preliminary data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse changes between interim data and final data could significantly harm our business and prospects. Further, additional disclosure of interim, topline or preliminary data by us or by our competitors in the future could result in volatility in the price of our common stock.
Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is typically selected from a more extensive amount of available information. You or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular drug, product candidate or our business. If the interim, topline or preliminary data that we report differ from late, final or actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, entospletinib or any other product candidates may be harmed, which could harm our business, financial condition, results of operations and prospects.
59
If we are unable to successfully develop companion diagnostic tests for our product candidates that require such tests, experience significant delays in doing so, or are unable to obtain any necessary FDA approvals of such tests, we may not be able to obtain approval for our product candidates, may be delayed in doing so, or may not realize the full commercial potential of these product candidates.
In developing a product candidate for certain indications, we may decide to use a biomarker-based test to identify patients for enrollment and, or, monitor patients in clinical trials. For example, we are using a biomarker-based test to identify patients for enrollment in our ongoing registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy for the treatment of AML patients with NPM1 mutations. If the FDA determines that a companion diagnostic device is essential to the safe and effective use of a novel therapeutic product or indication, the FDA generally will not approve the therapeutic product or new therapeutic product indication if the companion diagnostic is not also approved or cleared for that indication. The FDA generally requires contemporaneous approvals of a new companion diagnostic with the proposed therapeutic. To date, the FDA has required premarket approval of all companion diagnostics for cancer therapies. As such, if a satisfactory companion diagnostic is not commercially available, we may be required to create or obtain one that would be subject to regulatory approval or clearance requirements.
We plan to develop, either by ourselves or with collaborators, companion diagnostic tests for our product candidates for certain indications, which will include entospletinib for the treatment of AML patients with NPM1 mutations and lanraplenib for the treatment of AML patients with FLT3 mutations. To be successful, we or our collaborators will need to address a number of scientific, technical, regulatory and logistical challenges. Companion diagnostics are regulated as medical devices, and we have no prior experience with medical device or diagnostic test development. If we choose to or are required to develop and seek FDA approval for companion diagnostic tests on our own, we will require additional personnel. We may rely on third parties for the design, development and manufacture of companion diagnostic tests for our product candidates that require such tests. If these parties are unable to successfully develop companion diagnostics for these product candidates, or experience delays in doing so, we may be unable to enroll enough patients for our current and planned clinical trials, the development of these product candidates may be adversely affected, these product candidates may not obtain marketing approval, and we may not realize the full commercial potential of any of these products that obtain marketing approval. As a result, our business, results of operations and financial condition could be materially harmed.
The COVID-19 pandemic could continue to adversely impact our business, including our ongoing or planned clinical trials.
The COVID-19 pandemic in the United States and in other countries in which we have ongoing and planned clinical trials and where our current or future third party manufacturers or supply chain vendors operate, could cause significant disruptions that could severely impact our business and our planned clinical trials, including:
•delays or difficulties in screening and enrolling patients in our ongoing and planned clinical trials;
•delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;
•diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;
•inability or unwillingness of subjects to travel to the clinical trial sites;
•delays or difficulties in data collection and analysis and other related activities;
•decreased implementation of protocol-required clinical trial activities and quality of source data verification at clinical trial sites;
•interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others;
60
•limitations in employee resources that would otherwise be focused on the conduct of our clinical trials and our other research and development activities, including because of sickness of employees or their families or mitigation measures such as lock-downs and social distancing;
•delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;
•delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;
•interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our clinical trials;
•changes in local regulations as part of a response to the COVID-19 pandemic which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, delays, or to discontinue the clinical trials altogether;
•delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees;
•refusal of the FDA or foreign regulatory authorities to accept data from clinical trials in affected geographies; and
•adverse impacts on global economic conditions which could have an adverse effect on our business and financial condition, including impairing our ability to raise additional capital when needed.
Such disruptions could impede, delay, limit or prevent completion of our preclinical studies or commencement or the continuation of planned or other future clinical trials and ultimately lead to the delay or denial of regulatory approval of our product candidates, which would seriously harm our operations and financial condition and increase our costs and expenses. In addition, we also experienced delays in our discovery and development activities as a result of the COVID-19 pandemic, primarily due to temporary and partial shutdowns at certain of our CROs that have since resumed normal operations, and due to the previous California and Massachusetts stay-at-home orders where our operations are located. Future or revised stay-at-home orders could result in additional delays or otherwise negatively impact our discovery and development activities. The COVID-19 pandemic could also affect the business of the FDA or other health authorities which could result in delays in meetings related to our ongoing and planned clinical trials and ultimately of reviews and approvals of our product candidates. Moreover, to the extent the evolving effects of the COVID-19 pandemic adversely affect our business and financial condition, they may also have the effect of heightening many of the other risks and uncertainties described elsewhere in this “Risk Factors” section.
The global COVID-19 pandemic continues to rapidly evolve. The extent to which the COVID-19 pandemic may impact our business, preclinical development activities and ongoing and planned clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate duration and severity of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.
We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.
Because we have limited financial and managerial resources, we focus on research programs and product candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.
61
Our approach to the discovery and development of product candidates is unproven, and we may not be successful in our efforts to use and further develop our product engine to expand our pipeline of product candidates with commercial value.
A key element of our strategy is to use our product engine to further develop our pipeline of product candidates and progress these product candidates through clinical development and ultimately achieve approval for the treatment of various cancers by focusing on dysregulated transcription factors and the TRNs through which they drive oncogenic activity. The discovery and development activities that we are conducting may not be successful in developing product candidates that are useful in treating cancer or other diseases.
With respect to an internally developed product candidates, our research and development efforts to date have resulted in our discovery and preclinical development of KB-0742 as well as several early-stage discovery programs. KB-0742 may not be safe or effective as a cancer treatment and, with respect to our early-stage discovery programs, we may not identify suitable product candidates for preclinical or clinical development. Our product engine may not be successful in generating additional contributions to our pipeline of product candidates. For example, we may not be successful in identifying novel product candidates that can selectively modulate oncogenic TRNs. Even if we are successful in building our pipeline of product candidates, the potential product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable toxicity or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future, which likely would result in significant harm to our financial position and adversely affect our stock price.
As a company, we have not completed any clinical trials to date.
We have not as a company completed any clinical trials to date. We therefore cannot be certain that our ongoing Phase 1/2 clinical trial of KB-0742, our ongoing Phase 3 clinical trial of entospletinib or our planned clinical trials will begin or be completed on time, or at all. In addition, the ongoing COVID-19 pandemic may create additional challenges in initiating, enrolling or conducting such clinical trials.
In addition, large-scale clinical trials require significant financial and management resources and reliance on third-party clinical investigators, CROs, CMOs and consultants. Relying on third-party clinical investigators, CROs, CMOs and consultants may force us to encounter delays that are outside of our control. We may be unable to identify and contract with sufficient investigators, CROs, CMOs and consultants on a timely basis, or at all.
Because of the relatively small number of patients that is being or planned to be dosed in our Phase 1/2 trial of KB-0742, the results from such clinical trial, if completed, may be less reliable than results achieved in larger clinical trials, which may hinder our efforts to further develop and obtain regulatory approval for this product candidate.
In our Phase 1/2 clinical trial of KB-0742, we are evaluating the safety, PK and PD profile of KB-0742 in patients with advanced solid tumors, and we plan to define an optimal dose and schedule for expansion cohorts in cancer patients with MYC-amplified solid tumors and other transcriptionally addicted cancers. As of an October 1, 2021 data cutoff, 12 patients had been dosed, and though enrollment is still ongoing, the total number of patients we expect to enroll in this clinical trial will be significantly smaller than the number of patients that would need to be enrolled in a registrational or other late-stage clinical trial. The results of clinical trials with smaller sample sizes, such as our ongoing Phase 1/2 clinical trial of KB-0742, can be disproportionately influenced by various biases associated with the conduct of small clinical trials, such as the potential failure of the smaller sample size to accurately depict the features of the broader patient population, which limits the ability to generalize the results across a broader community, thus making the clinical trial results less reliable than clinical trials with a larger number of patients. As a result, there may be less certainty that such product candidates would achieve a statistically significant effect in any future clinical trials. If we conduct any future clinical trials of KB-0742, we may not achieve a statistically significant result or the same level of statistical significance, if any, that we might have anticipated based on the results observed in our initial Phase 1/2 clinical trial.
62
Risks Related to the Commercialization of Our Product Candidates
If the market opportunities for our product candidates are smaller than we estimate or if any approval that we obtain is based on a narrower definition of the patient population, it will adversely affect our revenue potential and ability to achieve profitability.
The total addressable market opportunity for entospletinib and our other product candidates will ultimately depend upon, among other things, the final label for each product candidate, acceptance by the medical community and patient access, drug and any related companion diagnostic pricing and reimbursement. The number of patients in our targeted commercial markets and elsewhere may turn out to be lower than expected, patients may not be amenable to treatment with our products, or new patients may become increasingly difficult to identify, all of which would adversely affect our results of operations and our business.
The market opportunities for certain of our product candidates may be relatively small as they may be limited to those patients who are ineligible for or have failed prior treatments and our estimates of the prevalence of our target patient populations may be inaccurate.
Cancer therapies are sometimes characterized as first line, second line, or third line, and the FDA often approves new therapies initially only for a particular line of use. When cancer is detected early enough, first line therapy is sometimes adequate to cure the cancer or prolong life without a cure. Whenever first line therapy, usually chemotherapy, antibody drugs, tumor-targeted small molecules, hormone therapy, radiation therapy, surgery, or a combination of these, proves unsuccessful, second line therapy may be administered. Second line therapies often consist of more or different chemotherapy, radiation, antibody drugs, tumor-targeted small molecules, or a combination of these. Third line therapies can include chemotherapy, antibody drugs and small molecule tumor-targeted therapies, more invasive forms of surgery and new technologies. Although we have initiated with our randomized, double-blinded, placebo-controlled registrational Phase 3 clinical trial of entospletinib in combination with intensive chemotherapy in approximately 180 newly diagnosed NPM1-mutated AML patients, in some instances we may initially seek approval of our product candidates as a second- or third-line therapy. Subsequently, for those product candidates that prove to be sufficiently safe and beneficial, if any, we would expect to seek approval as a second line therapy and potentially as a first line therapy, but there is no guarantee that our product candidates, even if approved as a second or third or subsequent line of therapy, would be approved for an earlier line of therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.
Our projections of both the number of people who have the cancers we are targeting, who may have their tumors genetically sequenced, as well as the subset of people with these cancers in a position to receive a particular line of therapy and who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new therapies may change the estimated incidence or prevalence of the cancers that we are targeting. Consequently, even if our product candidates are approved for a second or third line of therapy, the number of patients that may be eligible for treatment with our product candidates may turn out to be much lower than expected. In addition, we have not yet conducted market research to determine how treating physicians would expect to prescribe a product that is approved for multiple tumor types if there are different lines of approved therapies for each such tumor type.
Even if any of our product candidates are approved, they may not achieve adequate market acceptance among physicians, patients, healthcare payors and others in the medical community necessary for commercial success.
The degree of market acceptance of any of our approved product candidates will depend on a number of factors, including:
•the efficacy and safety profile as demonstrated in clinical trials compared to alternative treatments, as well as other perceived advantages and disadvantages;
•the approval, availability, market acceptance, and reimbursement of any companion diagnostic;
•the timing of market introduction of the product candidate as well as competitive products;
63
•the clinical indications for which the product candidate is approved;
•restrictions on the use of our product candidates, such as boxed warnings or contraindications in labeling, or a REMS, if any, which may not be required of alternative treatments and competitor products;
•the ability to offer the product candidate for sale at competitive prices;
•the availability of coverage and adequate reimbursement by third-party payors, including government authorities;
•acceptance by hospital pharmacy and therapeutics committees in the U.S., E.U., and other geographies;
•the availability of the approved product candidate for use as a combination therapy, where applicable;
•the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
•the strength of marketing and distribution support;
•unfavorable publicity relating to our products or product candidates or similar approved products or product candidates in development by third parties; and
•the approval of other new therapies for the same indications.
If any of our product candidates is approved but does not achieve an adequate level of acceptance by physicians, hospitals, healthcare payors and patients, we may not generate or derive sufficient revenue from that product candidate and our financial results could be negatively impacted.
We currently have no marketing and sales organization and have no experience as a company in marketing products. If we are unable to establish and maintain marketing and sales capabilities or enter into agreements with third parties to market and sell our product candidates, if approved, we may not be able to generate product revenue.
We currently have no sales, marketing, market access or distribution capabilities and have no experience as a company in marketing products. We currently intend to build a commercial infrastructure to support sales of our product candidates. We expect to manage sales, marketing, market access and distribution through internal resources and third-party relationships. We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing, market access and sales personnel. While we may commit significant financial and management resources to commercial activities, we will also consider collaborating with one or more pharmaceutical companies to enhance our commercial capabilities.
If we are unable or decide not to establish internal sales, marketing and distribution capabilities in the United States, or all other geographic regions, we will pursue arrangements with third-party sales, marketing, and distribution collaborators regarding the sales and marketing of our products, if approved. However, there can be no assurance that we will be able to establish or maintain such arrangements on favorable terms or if at all, or if we are able to do so, that these third-party arrangements will provide effective sales forces or marketing and distribution capabilities. Any revenue we receive will depend upon the efforts of such third parties, which may not be successful. We may have little or no control over the marketing and sales efforts of such third parties and our revenue from product sales may be lower than if we had commercialized our product candidates ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts of our product candidates.
There can be no assurance that we will be able to develop in-house sales and distribution capabilities or establish or maintain relationships with third-party collaborators to commercialize any product in the United States or overseas.
64
Product liability lawsuits could cause us to incur substantial liabilities and could limit the commercialization of any product candidates that we develop.
Our business exposes us to significant product liability risks inherent in the development, testing, manufacturing and marketing of therapeutic treatments. Product liability claims could delay or prevent completion of our development programs. If we succeed in marketing products, such claims could result in an FDA, EMA or other regulatory authority investigation of the safety and effectiveness of our products, our manufacturing processes and facilities or our marketing programs. FDA, EMA or other regulatory authority investigations could potentially lead to a recall of our products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources and substantial monetary awards to trial participants or patients. We currently have product liability insurance that we believe is appropriate for our stage of development and may need to obtain higher levels prior to marketing any of our product candidates, if approved. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have an adverse effect on our business and financial condition.
Any product candidates we develop may become subject to unfavorable third-party coverage and reimbursement policies, third-party reimbursement practices, or health care reform initiatives, which could harm our business.
The availability and extent of coverage and adequate reimbursement by third-party payors, including government health administration authorities, private health coverage insurers, managed care organizations and other third-party payors is essential for most patients to be able to afford expensive treatments. Sales of any of our product candidates that receive marketing approval will depend substantially, both in the United States and internationally, on the extent to which the costs of our product candidates will be covered and reimbursed by third-party payors. If coverage is not available, or is available only to limited indications or strict coverage criteria, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize an adequate return on our investment. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or reimbursement is available only to limited levels, we may not successfully commercialize any product candidate for which we obtain marketing approval. In addition, companion diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for their companion pharmaceutical or biological products. Similar challenges to obtaining coverage and reimbursement, applicable to pharmaceutical or biological products, will apply to companion diagnostics.
There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved products. In the United States, third-party payors, including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new drugs will be covered and reimbursed. The Centers for Medicare & Medicaid Services (CMS), an agency within the U.S. Department of Health and Human Services (HHS) responsible for administering the Medicare program, determines whether and to what extent a new product will be covered and reimbursed under Medicare. One third-party payor’s determination to provide coverage for a drug product, however, does not assure that other payors will also provide coverage for the product. As a result, the coverage determination process is often time-consuming and costly. This process may require us to provide scientific and clinical support for the use of our products to each third-party payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.
For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization.
65
Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Further, such payors are increasingly challenging the price, examining the medical necessity and reviewing the cost effectiveness of medical product candidates. There may be significant delays in obtaining coverage and reimbursement for newly approved drugs. Third-party payors may limit coverage to specific product candidates on an approved list, known as a formulary, which might not include all FDA-approved drugs for a particular indication. We may need to conduct expensive pharmacoeconomic studies to demonstrate the medical necessity and cost effectiveness of our products. Nonetheless, our product candidates may not be considered medically necessary or cost effective. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be.
Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost containment initiatives in Europe, Canada and other countries has and will continue to put pressure on the pricing and usage of therapeutics such as our product candidates. In many countries, particularly the countries of the European Union, medical product prices are subject to varying price control mechanisms as part of national health systems. In these countries, pricing negotiations with governmental authorities can take considerable time after a product receives marketing approval. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. In general, product prices under such systems are substantially lower than in the United States. Other countries allow companies to fix their own prices for products, but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenue and profits.
If we are unable to establish or sustain coverage and adequate reimbursement for any future product candidates from third-party payors, the adoption of those products and sales revenue will be adversely affected, which, in turn, could adversely affect the ability to market or sell those product candidates, if approved. Coverage policies and third-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than we do.
The development and commercialization of pharmaceutical products is highly competitive. We face competition with respect to our current product candidates, and will face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of products for the treatment of the disease indications for which we are developing our product candidates. Some of these competitive products and therapies are based on scientific approaches that are similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.
There are a large number of pharmaceutical and biotechnology companies developing or marketing targeted treatments for cancer that would be competitive with the product candidates we are developing, if our product candidates are approved. Many of these companies are developing cancer therapeutics that are also kinase inhibitors.
If we are successful in developing entospletinib, our lead product candidate, or lanraplenib, our next-generation SYK inhibitor, they may compete against product candidates that are currently in clinical development to the extent any such candidates are approved, including: (i) HMPL-523, a SYK inhibitor being developed by Hutchison Medipharma Ltd. that is in Phase 1 evaluation in hematologic malignancies; (ii) product candidates in early clinical development that target the interaction between MLL and MENIN in MLL-r and AML patients with
66
NPM1 mutations, which, if approved, could compete with entosplentinib or lanraplenib, including (a) SNDX-5613, being developed by Syndax Pharmaceuticals, Inc. in a Phase 1 clinical trial as monotherapy in relapsed or refractory AML in patients with MLL-r/KMT2A gene rearrangement or NPM1 mutations; (b) KO-539, being developed by Kura Oncology, Inc. in a Phase 1 clinical trial as monotherapy in relapsed or refractory AML, (c) DS-1594, being developed by Daiichi Sankyo Company in a Phase 1 clinical trial with or without azacitidine/venetoclax in relapsed/refractory AML, and (d) JNJ-75276617, being developed by Janssen Research & Development, LLC in a Phase 1 clinical trial in acute leukemias; and (iii) product candidates that may compete with entosplentinib or lanraplenib by addressing the subset of AML patients with FLT3 mutations and are currently in development in combination with FLT3 inhibitors, including (a) venetoclax, a BCL-2 inhibitor being developed by Abbvie, and (b) CPX-351, a liposomal formulation of daunorubicin and cytarabine being developed by Jazz Pharmaceuticals.
If we are successful in developing KB-0742, it may compete against various multi-CDK inhibitors that are currently in early-stage clinical development, including: AZD4573, being developed by AstraZeneca; TP-1287 (alvocidib), being developed by Tolero Pharmaceuticals; fadraciclib (CYC-065), being developed by Cyclacel Pharmaceuticals; zotiraciclib, being developed by the National Cancer Institute; dinaciclib, being developed by Merck & Co.; and voruciclib, being developed by MEI Pharma. We also expect it to compete against VIP152, a PTEFb/CDK9 inhibitor in early-stage clinical development by Vincerx Pharma, Inc., and PRT2527, a CDK9 inhibitor in preclinical development by Prelude Therapeutics.
We also expect that our product candidates, if approved, will compete with more established therapies, such as intensive chemotherapy and HMAs to treat AML and other agents to treat MYC-amplified solid tumors and other transcriptionally addicted cancers.
Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining marketing approvals and marketing and selling approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific, management and sales and marketing personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are approved for broader indications or patient populations, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other marketing approval for their products more rapidly than any approval we may obtain for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. Generic products are currently on the market for some of the indications that we are pursuing, and additional products are expected to become available on a generic basis over the coming years. If our product candidates achieve marketing approval, we expect that they will be priced at a significant premium over any competitive generic products. The key competitive factors affecting the success of entospletinib are likely to be its efficacy, safety, scope and limitations of marketing approval, and availability of reimbursement.
A variety of risks associated with marketing our product candidates internationally could materially adversely affect our business.
We may seek marketing approvals of our product candidates outside of the United States and, accordingly, we may be subject to additional risks related to operating in foreign countries if we obtain the necessary foreign marketing approvals, including:
•differing regulatory requirements in foreign countries, for example, no country other than the United States has a pathway for accelerated drug approval and so obtaining regulatory approvals outside of the United States will take longer and be more costly than obtaining approval in the United States;
67
•differing intellectual property and regulatory laws in foreign countries, including the availability of obtaining patent term extensions, orphan disease status, or data exclusivity in those countries with respect to the patents covering our products;
•unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;
•economic weakness, including inflation, or political instability in particular foreign economies and markets;
•compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;
•foreign taxes, including withholding of payroll taxes;
•foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country;
•differing pricing, payment and reimbursement regimes;
•difficulties staffing and managing foreign operations;
•workforce uncertainty in countries where labor unrest is more common than in the United States;
•potential liability under the U.S. Foreign Corrupt Practices Act (FCPA) or comparable foreign regulations;
•challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect intellectual property rights to the same extent as the United States;
•production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
•business interruptions resulting from geo-political actions, including war and terrorism.
These and other risks associated with international operations may materially adversely affect our ability to attain or maintain profitable operations.
Risks Related to Regulatory Approval and Other Legal Compliance Matters
We may be unable to obtain U.S. or foreign regulatory approvals and, as a result, may be unable to commercialize our product candidates.
Rigorous preclinical testing and clinical trials and an extensive regulatory approval process must be successfully completed in the United States and in many foreign jurisdictions before a new drug can be marketed. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. We cannot provide any assurance that any product candidate we may develop will progress through required clinical testing and obtain the regulatory approvals necessary for us to begin selling them.
As a company, we have not completed any clinical trials of any product candidates, nor have we managed the regulatory approval process with the FDA or any other regulatory authority. The time required to obtain approvals from the FDA and other regulatory authorities is unpredictable, and requires successful completion of extensive clinical trials which typically takes many years, depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when evaluating clinical trial data can and often changes during drug development, which makes it difficult to predict with any certainty how they will be applied. We may also encounter unexpected delays or increased costs due to new government regulations, including future legislation or administrative action, or changes in FDA policy during the period of drug development, clinical trials and FDA regulatory review.
Any delay or failure in seeking or obtaining required approvals would have a material and adverse effect on our ability to generate revenue from the particular product candidate for which we are developing and seeking approval. Furthermore, any regulatory approval to market a drug may be subject to significant limitations on the approved uses or indications for which we may market the drug or the labeling or other restrictions. In addition, the FDA has the authority to require a REMS as part of approving a NDA, or after approval, which may impose
68
further requirements or restrictions on the distribution or use of an approved drug. These requirements or restrictions might include limiting prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria and requiring treated patients to enroll in a registry. These limitations and restrictions may significantly limit the size of the market for the drug and affect reimbursement by third-party payors.
We are also subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries, and generally includes all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval.
We may in the future conduct clinical trials for our product candidates outside the United States, and the FDA and comparable foreign regulatory authorities may not accept data from such trials.
We are currently conducting a clinical trial, and may in the future choose to conduct one or more clinical trials outside the United States, or include study sites outside the United States, including in Europe or Asia. The acceptance of study data from clinical trials conducted outside the United States or another jurisdiction by the FDA or comparable foreign regulatory authority may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the sole basis of foreign data unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of recognized competence; and (iii) the data are considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Otherwise, for studies that are conducted at sites outside of the United States and not subject to an IND and which are intended to support a marketing application, the FDA requires the clinical trial to have been conducted in accordance with good clinical practice (GCP) requirements and the FDA must be able to validate the data from the clinical trial through an onsite inspection if it deems such inspection necessary. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time-consuming, and which may result in product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction.
Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.
Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction. For example, even if the FDA grants regulatory approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion and reimbursement of the product candidate in those countries. However, a failure or delay in obtaining regulatory approval in one the regulatory approval process in others. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.
Obtaining foreign regulatory approvals and establishing and maintaining compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any future collaborator fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.
69
Even if our product candidates receive regulatory approval, they will be subject to significant post-marketing regulatory requirements and oversight. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions on marketing or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems.
Following any regulatory approvals, our products will be subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of drugs. Any regulatory approvals that we may receive for our product candidates will require the submission of reports to regulatory authorities and surveillance to monitor the safety and efficacy of the product candidate, may contain significant limitations related to use restrictions for specified age groups, warnings, precautions or contraindications, and may include burdensome post-approval study or risk management requirements. For example, the FDA may require a REMS in order to approve our product candidates, which could entail requirements for a medication guide, physician training and communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or foreign regulatory authorities approve our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as on-going compliance with cGMPs and GCP for any clinical trials that we conduct post-approval. In addition, manufacturers of drug products and their facilities are subject to continual review and periodic, unannounced inspections by the FDA and other regulatory authorities for compliance with cGMP regulations and standards. If we or a regulatory agency discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facilities where the product is manufactured, a regulatory agency may impose restrictions on that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing. In addition, failure to comply with FDA and comparable foreign regulatory requirements may subject our company to administrative or judicially imposed sanctions, including:
•delays in or the rejection of product approvals;
•restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;
•restrictions on the products, manufacturers or manufacturing process;
•warning or untitled letters;
•civil and criminal penalties;
•injunctions;
•suspension or withdrawal of regulatory approvals;
•product seizures, detentions or import bans;
•voluntary or mandatory product recalls and publicity requirements;
•total or partial suspension of production; and
•imposition of restrictions on operations, including costly new manufacturing requirements.
The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue and could require us to expend significant time and resources in response and could generate negative publicity.
70
The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, and we may not achieve or sustain profitability.
We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. For example, certain policies of the current U.S. administration may impact our business and industry.
If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.
The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.
If any of our product candidates are approved and we are found to have improperly promoted off-label uses of those products, we might become subject to significant liability. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription pharmaceutical products, such as our product candidates. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we receive marketing approval for a product candidate, physicians may nevertheless prescribe it to their patients in a manner that is inconsistent with the approved label based on the physician’s independent medical judgment. However, if we are found to have promoted such off-label uses, we may become subject to significant liability. The U.S. federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully manage the promotion of our product candidates, if approved, we could become subject to significant liability, which would materially adversely affect our business and financial condition.
If we are required by the FDA to obtain approval of a companion diagnostic test in connection with approval of any of our product candidates, and we do not obtain or face delays in obtaining FDA approval of a diagnostic device, we will not be able to commercialize such product candidate and our ability to generate revenue will be materially impaired.
If safe and effective use of any of our product candidates depends on an in vitro diagnostic that is not otherwise commercially available, then the FDA generally will require approval or clearance of that diagnostic, known as a companion diagnostic, at the same time that the FDA approves our product candidates if at all. If a satisfactory companion diagnostic is not commercially available, we may be required to create or obtain one that would be subject to regulatory approval requirements. The process of obtaining or creating such diagnostic is time consuming and costly.
Companion diagnostics are developed in conjunction with clinical programs for the associated therapeutic product candidate and are subject to regulation as medical devices by the FDA and comparable regulatory authorities, and, to date, the FDA has required premarket approval of all companion diagnostics for cancer therapies. The approval of a companion diagnostic as part of the therapeutic product’s labeling limits the use of the therapeutic product to only those patients who express the specific genetic alteration that the companion diagnostic was developed to detect.
If the FDA or a comparable foreign regulatory authority requires approval of a companion diagnostic for any of our product candidates, whether before or after it obtains marketing approval, we, and/or future collaborators, may encounter difficulties in developing and obtaining approval for such product candidate. Any delay or failure by us or third-party collaborators to develop or obtain regulatory approval of a companion diagnostic could delay or prevent approval or continued marketing of such product candidate.
We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process for the companion diagnostic or in transferring that process to commercial partners or negotiating
71
insurance reimbursement plans, all of which may prevent us from completing our clinical trials or commercializing our product candidate, if approved, on a timely or profitable basis, if at all.
Disruptions at the FDA, the SEC or other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.
The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC, and other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.
Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, in recent years, including in 2018 and 2019, the U.S. government shut down several times and certain regulatory agencies, such as the FDA and the SEC, had to furlough critical employees and stop critical activities. Separately, in response to the COVID-19 pandemic, in March 2020 the FDA announced its intention to postpone most inspections of foreign and domestic manufacturing facilities and products and in July 2020 resumed certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA intends to use this risk-based assessment system to identify the categories of regulatory activity that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns or delays could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
72
We plan to attempt to secure approval for entospletinib and possibly other of our product candidates from the FDA or comparable foreign regulatory authorities through the use of accelerated approval pathways, which is uncertain. If we are unable to obtain such approval, we may be required to conduct additional preclinical studies or clinical trials beyond those that we contemplate, which could increase the expense of obtaining, and delay the receipt of, necessary marketing approvals. Even if we receive accelerated approval from the FDA, if our trials required as a condition to such accelerated approval do not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA may withdraw approval.
We plan to seek accelerated approval for entospletinib and may in the future seek an accelerated approval for one or more of our other product candidates. Under the accelerated approval program, the FDA may grant accelerated approval to a product candidate designed to treat a serious or life-threatening condition that provides meaningful therapeutic benefit over available therapies upon a determination that the product candidate has an effect on a surrogate endpoint, such as MRD-negative CR, or intermediate clinical endpoint that it determines is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. If granted, accelerated approval is usually contingent, or conditioned on the sponsor’s agreement to conduct additional post-approval confirmatory studies or extend one or more existing trials to capture additional endpoints to verify and describe the drug’s clinical benefit. If such post-approval studies fail to confirm the drug’s clinical benefit, the FDA may withdraw its approval of the drug. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Even if we do receive accelerated approval, we may not experience a faster development or regulatory review or approval process, and receiving accelerated approval does not provide assurance of ultimate FDA approval.
Prior to seeking accelerated approval for any of our product candidates, we intend to seek feedback from the FDA and will otherwise evaluate our ability to seek and receive accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit an NDA for accelerated approval or any other form of expedited development, review or approval. Similarly, there can be no assurance that after subsequent FDA feedback we will continue to pursue or apply for accelerated approval or any other form of expedited development, review or approval, even if we initially decide to do so.
We may face difficulties from changes to current regulations and future legislation.
Existing regulatory policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.
73
For example, in March 2010, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the ACA), was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. There have been executive, judicial and Congressional challenges to certain aspects of the ACA. For example, on June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling. on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace, which began on February 15, 2021 and remained open through August 15, 2021. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. It is unclear how any such challenges and litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our business.
In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, will stay in effect through 2031 unless additional congressional action is taken. However, COVID-19 relief legislation suspended the 2% Medicare sequester from May 1, 2020 through March 31, 2022. Under current legislation the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. Additionally, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our drugs, if approved, and accordingly, our financial operations.
Moreover, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. For example, at the federal level, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. On July 24, 2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that attempt to implement several of the administration’s proposals. The FDA also released a final rule and guidance implementing a portion of the importation executive order providing pathways for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed until January 1, 2023. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. As a result of litigation challenging the Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded the Most Favored Nation model interim final rule .
In July 2021, the Biden administration release an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to President Biden’s executive order, on September 9, 2021, HHS release a Comprehensive Plain for Addressing High Drug Prices that outlines
74
principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as part of the budget reconciliation process. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.
We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to attain profitability or commercialize our product candidates. It is possible that additional governmental action is taken in response to the COVID-19 pandemic.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for biotechnology products. We cannot be sure whether additional legislative changes will be enacted, or whether FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be.
Our relationships with healthcare professionals, clinical investigators, CROs and third party payors in connection with our current and future business activities may be subject to federal and state healthcare fraud and abuse laws, false claims laws, transparency laws, and government price reporting, which could expose us to, among other things, criminal sanctions, administrative and civil penalties, contractual damages, exclusion from governmental healthcare programs, reputational harm, administrative burdens and diminished profits and future earnings.
Healthcare providers and third-party payors play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, clinical investigators, CROs, third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we conduct our research as well as market, sell and distribute our products for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations include the following:
•the federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation.
•the federal false claims laws, including the civil False Claims Act, which can be enforced by private citizens through civil whistleblower or qui tam actions, and civil monetary penalties laws, prohibit individuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act;
•the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA), prohibits, among other things, executing or attempting to execute a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;
•the federal Physician Payments Sunshine Act requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the
75
Children’s Health Insurance Program, with specific exceptions, to annually report to CMS information regarding payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as physician assistants and nurse practitioners), and teaching hospitals, as well as information regarding ownership and investment interests held by physicians and their immediate family members. The information reported is publicly available on a searchable website, with disclosure required annually;
•analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, that may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; and
•some state laws that require biotechnology companies to comply with the biotechnology industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government and may require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; some state laws that require biotechnology companies to report information on the pricing of certain drug products; and certain state and local laws that require the registration of pharmaceutical sales representatives.
Efforts to ensure that our current and future business arrangements with third parties will comply with applicable healthcare laws and regulations will involve on-going substantial costs. It is possible that governmental authorities will conclude that our business practices, including, without limitation, our consulting agreements with certain physicians, who may be in a position to order and/or influence the purchase of our product candidates, if approved, and are compensated in the form of stock or stock options for services provided to us, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting obligations, contractual damages, reputational harm, diminished profits and future earnings and the curtailment or restructuring of our operations. Defending against any such actions can be costly, time-consuming and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. Further, if any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusion from government funded healthcare programs.
We are subject to stringent and changing obligations related to data privacy and information security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation; fines and penalties; a disruption of our business operations; reputational hard; and other adverse business impacts.
In the ordinary course of business, we maintain and process, and our third-party vendors, collaborators, contractors and consultants maintain and process on our behalf, a large quantity of sensitive data, including confidential business, personal and patient health data in connection with our preclinical studies, clinical trials and our employees, and are subject to data privacy and information security laws and regulations that apply to the collection, transmission, storage and use of personal data, which among other things, impose certain requirements relating to the privacy, security and transmission of personal data. We are also subject to internal and external privacy and security policies, contracts and other obligations that apply to our processing of sensitive information or processing of sensitive information on our behalf. In addition, privacy advocates and industry groups have regularly proposed, and may propose in the future, self-regulatory standards that may legally or contractually apply to us.
In the United States, there are numerous federal, state and local privacy and data security laws and regulations governing the collection, use, disclosure and protection of personal data, including federal and state health information privacy laws, federal and state security breach notification laws, and federal, state and local consumer protection laws, to which we are or may become subject. In particular, regulations promulgated pursuant to HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (HITECH), establish privacy and security standards that limit the use and disclosure of certain individually
76
identifiable health data, or protected health data, and require the implementation of administrative, physical and technological safeguards to protect the privacy of protected health data and ensure the confidentiality, integrity and availability of electronic protected health data. Determining whether protected health data has been handled in compliance with applicable privacy standards and our contractual obligations can be complex and may be subject to changing interpretation. Further, if we fail to comply or perceived to have not fully complied with applicable privacy laws, including applicable HIPAA privacy and security standards, we could face significant administrative, civil and criminal penalties. HHS has the discretion to impose penalties without attempting to first resolve violations. HHS enforcement activity can result in financial liability and reputational harm, and responses to such enforcement activity can consume significant internal resources. In addition, state attorneys general are authorized to bring civil actions seeking either injunctions or damages in response to violations that threaten the privacy of state residents. We cannot be sure how these regulations will be interpreted, enforced or applied to our operations. In addition to the risks associated with enforcement activities and potential contractual liabilities, our ongoing efforts to comply with evolving laws and regulations at the federal and state level may be costly and require ongoing modifications to our policies, procedures and systems.
In addition, the California Consumer Privacy Act of 2018 (CCPA) imposes obligations on business to which it applies. These obligations include, without limitation, providing specific disclosures in privacy notices, affording California residents certain rights related to their personal data, and requiring businesses subject to the CCPA to implement certain measures to effectuate California residents’ personal data rights. The CCPA allows for statutory fines for noncompliance up to $7500 per violation. In addition, it is anticipated that the California Privacy Rights Acts of 2020 (CPRA), effective January 1, 2023, will expand the CCPA. For example, the CPRA established a new California Privacy Protection Agency to implement and enforce the CCPA (as amended), which could increase the risk of an enforcement action. Other states have enacted data privacy laws. For example, Virginia passed its Consumer Data Protection Act, and Colorado passed the Colorado Privacy Act, both of which differ from the CPRA and become effective in 2023.
Outside the United States, an increasing number of laws, regulations, and industry standards apply to data privacy and security. For example, the European Union’s General Data Protection Regulation (EU GDPR) and the United Kingdom’s GDPR (UK GDPR) impose strict requirements for processing of personal data of individuals located, respectively, within the European Economic Area (EEA) and the United Kingdom (UK). For example, under the EU GDPR, government regulators may impose temporary or definitive bans on data processing, as well as fines of up to 20 million Euros or 4% of the annual global revenue of the company, whichever is greater. Further, individuals may initiate litigation related to our processing of their personal data.
Certain jurisdictions have enacted data localization laws and cross-border personal data transfers laws. For example, absent appropriate safeguards or other circumstances, the EU GDPR generally restricts the transfer of personal data to countries outside of the EEA, such as the United States, which the European Commission does not consider to provide an adequate level of personal data protection. The European Commission released a set of “Standard Contractual Clauses” that are designed to be a valid mechanism by which entities can transfer personal data out of the EEA to jurisdictions that the European Commission has not found to provide an adequate level of protection. Currently, these Standard Contractual clauses are a valid mechanism to transfer personal data outside of the EEA. The Standard Contractual Clauses, however, require parties that rely upon that legal mechanism to comply with additional obligations such as conducting transfer impact assessments to determine whether additional security measures are necessary to protect the at-issue personal data. Moreover, due to potential legal challenges, there exists some uncertainty regarding whether the Standard Contractual Clauses will remain a valid mechanism for personal data transfers out of the EEA. In addition, laws in Switzerland and the UK similarly restrict personal data transfers outside of those jurisdictions to countries such as the United States of America that do not provide an adequate level of personal data protection. In addition to European restrictions on cross-border personal data transfers, other jurisdictions have enacted or are considering similar cross-border personal data transfer laws and local personal data residency laws, any of which could increase the cost and complexity of doing business. If we cannot implement a valid compliance mechanism for cross-border personal data transfers, we may face increased exposure to regulatory actions, substantial fines, and injunctions against processing or transferring personal data from Europe or elsewhere. Inability to import personal data to the United States may significantly and negatively impact our business operations, including by limiting our ability to conduct clinical trial activities in Europe and elsewhere; limiting our ability to collaborate with parties subject to European and other data protection laws or requiring us to increase our personal data processing capabilities in Europe and/or elsewhere at significant expense.
77
Our obligations related to data privacy and security are quickly changing in an increasingly stringent fashion. These obligations may be subject to differing applications and interpretations, which may be inconsistent among jurisdictions or in conflict. Preparing for and complying with these obligations requires us to devote significant resources (including, without limitation, financial and time-related resources). These obligations may necessitate changes to our information technologies, systems, and practices and those of any third parties that process personal data on our behalf. In addition, these obligations may even require us to change to our business model. Although we endeavor to comply with all applicable data privacy and security obligations, we may at times fail (or be perceived to have failed) to do so. Moreover, despite our efforts, our personnel or third-parties upon whom we rely may fail to comply such obligations that impacts our compliance posture. If we fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could face significant consequences. These consequences may include, but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections and similar); litigation (including class-related claims); additional reporting requirements and/or oversight; bans on processing personal data; orders to destroy or not use personal data; and imprisonment of company officials.
Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations (including, as relevant, clinical trials); inability to process personal data or operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or revision or restructuring our operations.
The withdrawal of the United Kingdom from the European Union, commonly referred to as “Brexit,” may adversely impact our ability to obtain regulatory approvals of our product candidates in the European Union, result in restrictions or imposition of taxes and duties for importing our product candidates into the European Union, and may require us to incur additional expenses in order to develop, manufacture and commercialize our product candidates in the European Union.
Following the result of a referendum in 2016, the United Kingdom left the European Union on January 31, 2020, commonly referred to as “Brexit.” Pursuant to the formal withdrawal arrangements agreed between the United Kingdom and the European Union, the United Kingdom was subject to a transition period that ended December 31, 2020, or the Transition Period, during which EU rules continued to apply. A trade and cooperation agreement, or the Trade and Cooperation Agreement, that outlines the future trading relationship between the United Kingdom and the European Union was agreed in December 2020.
Since a significant proportion of the regulatory framework in the United Kingdom applicable to our business and our product candidates is derived from EU directives and regulations, Brexit has had, and may continue to have, a material impact on the regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product candidates in the United Kingdom or the European Union. For example, Great Britain is no longer covered by the centralized procedures for obtaining EU-wide marketing authorization from the EMA and, and a separate marketing authorization will be required to marker our product candidates in Great Britain. It is currently unclear whether the Medicines & Healthcare products Regulatory Agency, or MHRA, in the U.K. is sufficiently prepared to handle the increased volume of marketing authorization applications that it is likely to receive.
While the Trade and Cooperation Agreement provides for the tariff-free trade of medicinal products between the UK and the EU there may be additional non-tariff costs to such trade which did not exist prior to the end of the Transition Period. Further, should the UK diverge from the EU from a regulatory perspective in relation to medicinal products, tariffs could be put into place in the future. We could therefore, both now and in the future, face significant additional expenses (when compared to the position prior to the end of the Transition Period) to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the UK It is also possible that Brexit may negatively affect our ability to attract and retain employees, particularly those from the EU. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the United Kingdom.
78
Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.
We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities. Misconduct by these parties could include failures to comply with FDA requirements, provide accurate information to the FDA, comply with federal and state health care fraud and abuse laws and regulations, accurately report financial information or data or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the health care industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct by these parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting obligations, contractual damages, reputational harm, diminished profits and future earnings and the curtailment or restructuring of our operations.
If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on our business.
We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.
Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of hazardous and flammable materials, including chemicals and biological materials.
In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or commercialization efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.
Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.
Certain laws and regulations require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted, delayed or become more expensive.
79
We may be subject to U.S. and foreign anti-bribery and anti-corruption laws with respect to our operations, as well as U.S. and certain foreign export controls, trade sanctions, and import laws and regulations. Non-compliance with these laws can subject us to criminal or civil liability and harm our business.
If we further expand our operations outside of the United States, we must dedicate additional resources to comply with numerous laws and regulations in each jurisdiction in which we plan to operate. Our business activities may be subject to the FCPA and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA generally prohibits companies and their employees and third party intermediaries from offering, promising, giving or authorizing the provision of anything of value, either directly or indirectly, to a non-U.S. government official in order to influence official action or otherwise obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-U.S. governments. Additionally, in many other countries, hospitals owned and operated by the government, and doctors and other hospital employees would be considered foreign officials under the FCPA. Recently the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical companies. There is no certainty that all of our employees, agents or contractors, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, disgorgement, and other sanctions and remedial measures, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in one or more countries and could materially damage our reputation, our brand, our international activities, our ability to attract and retain employees and our business, prospects, operating results and financial condition.
In addition, our products and activities may be subject to U.S. and foreign export controls, trade sanctions and import laws and regulations. Governmental regulation of the import or export of our products, or our failure to obtain any required import or export authorization for our products, when applicable, could harm our international sales and adversely affect our revenue. Compliance with applicable regulatory requirements regarding the export of our products may create delays in the introduction of our products in international markets or, in some cases, prevent the export of our products to some countries altogether. Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products and services to countries, governments, and persons targeted by U.S. sanctions. If we fail to comply with export and import regulations and such economic sanctions, penalties could be imposed, including fines and/or denial of certain export privileges. Moreover, any new export or import restrictions, new legislation or shifting approaches in the enforcement or scope of existing regulations, or in the countries, persons, or products targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export our products to existing or potential customers with international operations. Any decreased use of our products or limitation on our ability to export or sell access to our products would likely adversely affect our business.
80
Risks Related to Our Intellectual Property
Our success depends on our ability to protect our intellectual property and our proprietary technologies.
Our commercial success depends in part on our ability to obtain and maintain patent protection and trade secret protection for our product candidates, proprietary technologies and their uses, as well as our ability to operate without infringing the proprietary rights of others. If we or our licensors are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology or our product candidates, our competitive position could be harmed. We generally seek to protect our proprietary position by filing patent applications in the United States and abroad related to our product candidates, proprietary technologies and their uses that are important to our business. Our patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents issue from such applications, and then only to the extent the issued claims read on the technology. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technology, nor can there be any assurance that the patents, if issued, will not be infringed, designed around, invalidated or rendered unenforceable by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and such protection may not adequately protect our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly protect the intellectual property rights relating to our product candidates could have a material adverse effect on our financial condition and results of operations.
Although we have issued patents in the United States and foreign countries, we cannot be certain that the claims in our other pending U.S. patent applications, corresponding international patent applications and patent applications in certain foreign countries will be considered patentable by the United States Patent and Trademark Office (USPTO), courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued patents will not be found invalid or unenforceable if challenged.
The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or our licensors or any of our potential future collaborators will be successful in protecting our technologies and product candidates by obtaining and defending patents. These risks and uncertainties include the following:
•the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process, the noncompliance with which can result in abandonment or lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction;
•patent applications may not result in any patents being issued;
•patents may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable or otherwise may not provide any competitive advantage;
•our competitors, many of which have substantially greater resources than we or our licensors have and many of which have made significant investments in competing technologies, may seek or may have already obtained patents that could or will limit, interfere with or block our ability to make, use and sell our product candidates;
•there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and
•countries other than the United States may have patent laws less favorable to patentees than those upheld by U.S. courts, allowing foreign competitors a better opportunity to create, develop and market competing products.
81
The patent prosecution process is also expensive and time-consuming, and we or our licensors may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we or our licensors may not identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some circumstances, we do not have the right to control, or are subject to certain obligations with respect to, the preparation, filing and prosecution of patent applications, or to maintain the patents, directed to technology that we license or acquire, including those from our licensors and from third parties. We also may require the cooperation of our licensors, whether current or future, in order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by our licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property that we in-license, and as a result our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to prevent competitors from making, using and selling competing products. Furthermore, the terms of the license agreements with some of our licensors may be non-exclusive, such that we would have no rights to enforce the licensed intellectual property against a competitor.
In addition, although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, outside scientific collaborators, CROs, third-party manufacturers, consultants, advisors, licensors, and other third parties, any of these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection.
If we fail to comply with our obligations in the agreements under which we license or otherwise acquire intellectual property rights from our licensors and third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business or our business may otherwise be materially harmed.
In July 2020, we acquired a portfolio of selective, orally bioavailable small molecule SYK inhibitors from Gilead, including entospletinib and lanraplenib, pursuant to the Gilead Asset Purchase Agreement. We also have a non-exclusive worldwide right to certain patents under a license agreement with Harvard University that provides us with rights to use the SMM screen, which is a key component of our product engine. These agreements impose on us, and we expect that any future license or other agreements where we in-license or acquire intellectual property will impose on us, various development, regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations.
We may need to obtain licenses or acquired intellectual property from third parties to advance our research or allow commercialization of our product candidates, and we cannot provide any assurances that third-party patents do not exist that might be enforced against our product candidates in the absence of such a license or acquisition. We may fail to obtain any of these licenses on commercially reasonable terms, if at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business, and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Licensing and acquisitions of intellectual property involve complex legal, business and scientific issues. Disputes may arise between us and our existing or future licensors and other third parties regarding intellectual property subject to a license or purchase agreement, including:
•the scope of rights granted under the license or purchase agreement and other interpretation-related issues;
•whether and the extent to which our technology and processes infringe intellectual property of the licensor or other third party that is not subject to the license or purchase agreement;
82
•our right to sublicense patents and other rights to third parties;
•our diligence obligations with respect to the use of the licensed or acquired technology in relation to our development and commercialization of our product candidates, and what activities satisfy those diligence obligations;
•the effects of termination;
•our right to transfer or assign the license or purchase agreement; and
•the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and their affiliates and sublicensees and by us and our partners and sublicensees.
The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property, or increase what we believe to be our financial or other obligations under the relevant agreement. And if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business.
In addition, certain of our agreements may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities.
If the scope of any patent protection we obtain is not sufficiently broad, or if we lose any of the patent protection we have, our ability to prevent our competitors from commercializing similar or identical product candidates would be adversely affected.
The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the existence, issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued that protect our product candidates or that effectively prevent others from commercializing competitive product candidates.
Moreover, the scope of claims in a patent application can be significantly reduced before any claims in a patent issue, and claim scope can be reinterpreted after issuance. Even if patent applications we currently have issue as patents in the future, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage.
Any patents that we have may be challenged or circumvented by third parties or may be narrowed or invalidated as a result of challenges by third parties. Consequently, we do not know whether our product candidates will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner, which could materially and adversely affect our business, financial condition, results of operations and prospects.
83
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may not cover our product candidates or may be challenged in the courts or patent offices in the United States and abroad. We may be subject to a third party pre-issuance submission of prior art to the USPTO, or become involved in opposition, derivation, revocation, reexamination, post-grant review (PGR), and inter partes review (IPR), or other similar proceedings in the USPTO or foreign patent offices challenging our patent rights. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to validity of our patents, for example, we cannot be certain that there is no invalidating prior art, of which we or third parties from whom we acquired our patents, their counsel, and the patent examiner were unaware during prosecution. There is no assurance that all potentially relevant prior art relating to our patents and patent applications has been found. There is also no assurance that there is not prior art of which we or third parties from whom we acquired patents and patent applications are aware, but which we or the third parties do not believe affects the validity or enforceability of a claim in our patents and patent applications, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate or render unenforceable, our patent rights, allow third parties to commercialize our product candidates and compete directly with us, without payment to us. Such loss of patent rights, loss of exclusivity or patent claims being narrowed, invalidated or held unenforceable could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our product candidates. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.
The patent protection and patent prosecution for some of our product candidates may be dependent on our licensors and third parties.
We or our licensors may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects as to form in the preparation or filing of our owned or in-licensed patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our licensors, whether current or future, fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our current or future licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our owned or in-licensed patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.
84
As a licensee of third parties, whether currently or in the future, we rely and may rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the licensed intellectual property under in-license agreements. We have not had, do not have, and may not have in the future, primary control over these activities for certain of our patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with some of our licensors, whether current or future, the licensors may have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents, and even if we are permitted to pursue such enforcement or defense, we will require the cooperation of our licensors. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If any of our licensors or any of our future licensors or future collaborators fails to appropriately prosecute and maintain patent protection for patents covering any of our product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using and selling competing products. Furthermore, the terms of the license agreements with some of our licensors may be non-exclusive, such that we would have no rights to enforce the licensed intellectual property against a competitor. In such cases, the licensors to our non-exclusive licenses may offer licenses to our competitors.
In addition, even where we have the right to control patent prosecution of patents and patent applications we have acquired or licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensors and their counsel that took place prior to us assuming control over patent prosecution.
Our technology acquired or licensed from various third parties, including our licensors, whether currently or in the future, may be subject to retained rights. Our licensors, whether current or future, may often retain certain rights under their agreements with us, including the right to use the underlying technology for use in fields other than the fields licensed to us or for use in noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.
If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be unable to successfully develop, out-license, market and sell our products, which could prevent or delay new product introductions. Our business strategy depends on the successful development of licensed and acquired technologies into commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell our product candidate.
Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business or permit us to maintain our competitive advantage. For example:
•others may be able to develop products that are similar to our product candidates but that are not within the scope of the claims of the patents that we own or license;
•we, third parties from whom we acquired intellectual property, or our licensors might not have been the first to make the inventions covered by the issued patents or patent application that we own or license;
•we, third parties from whom we acquired intellectual property, or our licensors might not have been the first to file patent applications directed to certain of our inventions;
•others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;
•it is possible that our pending patent applications will not lead to issued patents;
85
•issued patents that we own or license may be held invalid or unenforceable, as a result of legal challenges by our competitors;
•our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
•we may not develop additional proprietary technologies that are patentable; and
•the patents of others may have an adverse effect on our business.
Should any of these events occur, it could significantly harm our business, results of operations and prospects.
Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and commercialization efforts.
Our commercial success depends in part on avoiding infringement of the patents and proprietary rights of third parties. However, our research, development and commercialization activities may be subject to claims that we infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Other entities may have or obtain patents or proprietary rights that could limit our ability to make, use, sell, offer for sale or import our product candidates and products that may be approved in the future, or impair our competitive position. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biopharmaceutical industry, including patent infringement lawsuits, oppositions, reexaminations, inter partes review proceedings and post-grant review proceedings before the USPTO and/or foreign patent offices. Numerous third-party U.S. and foreign issued patents and pending patent applications exist in the fields in which we are developing product candidates. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates.
As the biopharmaceutical industry expands and more patents are issued, the risk increases that our product candidates may be subject to claims of infringement of the patent rights of third parties. Because patent applications are maintained as confidential for a certain period of time, until the relevant application is published, we may be unaware of third-party patents that may be infringed by development or commercialization of any of our product candidates, and we cannot be certain that we were the first to file a patent application related to a product candidate or technology. Moreover, because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates may infringe. In addition, identification of third-party patent rights that may be relevant to our technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. As such, we may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might subject us to infringement claims or adversely affect our ability to develop and market our product candidates. We cannot guarantee that any of our or our licensors’ patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent and pending patent application in the United States and abroad that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Any claims of patent infringement asserted by third parties would be time consuming and could:
•result in costly litigation that may cause negative publicity;
•divert the time and attention of our technical personnel and management;
•cause development delays;
•prevent us from commercializing any of our product candidates until the asserted patent expires or is held finally invalid or unenforceable or not infringed in a court of law;
86
•require us to develop non-infringing technology, which may not be possible on a cost-effective basis;
•subject us to significant liability to third parties; or
•require us to enter into royalty or licensing agreements, which may not be available on commercially reasonable terms, or at all, or which might be non-exclusive, which could result in our competitors gaining access to the same technology.
Although no third party has asserted a claim of patent infringement against us as of the date of this filing, others may hold proprietary rights that could prevent our product candidates from being marketed or could require us to pay significant royalties or other damages. Any patent-related legal action against us claiming damages and seeking to enjoin activities relating to our product candidates or processes could subject us to potential liability for damages, including treble damages if we were determined to willfully infringe, and require us to obtain a license, if available, to manufacture or develop our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and employee resources from our business. We cannot predict whether we would prevail in any such actions or that any license required under any of these patents would be made available on commercially acceptable terms, if at all. Moreover, even if we or our future strategic partners were able to obtain a license, the rights may be non-exclusive, which could result in our competitors gaining access to the same intellectual property. In addition, we cannot be certain that we could redesign our product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing and commercializing our product candidates, which could harm our business, financial condition and operating results.
Parties making claims against us may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.
We may become involved in lawsuits or administrative disputes to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming and unsuccessful.
Competitors and other third parties may infringe, misappropriate or otherwise violate our patents, trademarks, copyrights, trade secrets or other intellectual property. To counter infringement, misappropriation or other violations, we may be required to file infringement, misappropriation or other violation claims, which can be expensive and time-consuming and divert the time and attention of our management and business and scientific personnel. In addition, many of our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product or service. It may be difficult to detect infringers who do not advertise the components or methods that are used in connection with their products and services.
Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe, misappropriate or otherwise violate their patents or their other intellectual property, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In patent litigation in the United States, counterclaims challenging the validity, enforceability or scope of asserted patents are commonplace. Similarly, third parties may initiate legal proceedings against us seeking a declaration that certain of our intellectual property is not infringed, invalid or unenforceable. The outcome of any such proceeding is generally unpredictable.
87
In any patent infringement proceeding, there is a risk that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the invention. An adverse outcome in a litigation or proceeding involving our patents could limit our ability to assert our patents against those parties or other competitors, and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. If a defendant were to prevail on a legal assertion of invalidity or unenforceability of our patents covering one of our product candidates, we could lose at least a part, and perhaps all, of the patent protection covering such a product candidate. Competing drugs may also be sold in other countries in which our patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our infringement of a competitor’s patents, we could be prevented from marketing our drugs in one or more foreign countries. Any of these occurrences could adversely affect our competitive business position, business prospects and financial condition. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.
Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of shares of our common stock. Moreover, there can be no assurance that we will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.
Furthermore, third parties may also raise invalidity or unenforceability claims before administrative bodies in the United States or foreign authorities, even outside the context of litigation. Such mechanisms include re-examination, inter partes review, post-grant review, interference proceedings, derivation proceedings and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could result in revocation, cancellation or amendment to our patents in such a way that they no longer cover and protect our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, enablement or written description. Grounds for an unenforceability assertion could be an allegation that someone connected with the prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution of the patent. With respect to the validity of our patents, for example, we cannot be certain that there is no invalidating prior art of which we, third parties from whom we acquired patents and patent applications and their patent counsel, our licensors, our patent counsel, patent counsel for licensors or third parties, and the patent examiner were unaware during prosecution. Moreover, it is possible that prior art may exist that we, our licensors, or third parties from whom we acquired patents and patent applications are aware of but do not believe is relevant to our current or future patents, but that could nevertheless be determined to render our patents invalid. If a third party were to prevail on a legal assertion of invalidity or unenforceability, we could lose at least part, and perhaps all, of the patent protection on one or more of our product candidates. Any such loss of patent protection could have a material adverse impact on our business, financial condition, results of operations and prospects.
88
Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.
In September 2011, the Leahy-Smith America Invents Act (Leahy-Smith Act) was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. In particular, under the Leahy-Smith Act, the United States transitioned in March 2013 to a “first inventor to file” system in which, assuming that other requirements of patentability are met, the first inventor to file a patent application will be entitled to the patent regardless of whether a third party was first to invent the claimed invention. A third party that files a patent application in the USPTO after March 2013 but before the date of filing of our patents could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Furthermore, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our technology and the prior art allow our technology to be patentable over the prior art. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or the third parties from which we acquired our patents were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the inventions claimed in our patents or patent applications.
The Leahy-Smith Act also includes a number of significant changes that affect the way patent applications are prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including PGR, IPR, and derivation proceedings. An adverse determination in any such submission or proceeding could reduce the scope or enforceability of, or invalidate, our patent rights, which could adversely affect our competitive position.
Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. Thus, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our or licensors’ patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.
Changes in U.S. patent law, or laws in other countries, could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.
As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involve a high degree of technological and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time-consuming and inherently uncertain. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property and may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. In addition, Congress or other foreign legislative bodies may pass patent reform legislation that is unfavorable to us.
For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our or our licensors’ ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on legislation and decisions made by the U.S. Congress, the U.S. federal courts, the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our or our licensors’ ability to obtain new patents or to enforce our existing patents and patents we might obtain in the future.
89
We, Gilead, or our licensors, may be subject to claims by third parties asserting that our, Gilead’s, or our licensor’s, employees or consultants or we, Gilead, or our licensors, have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.
As is common in the biopharmaceutical industry, in addition to our employees, we engage the services of consultants to assist us in the development of our product candidates. Some of our employees and consultants, or employees or consultants of Gilead or our licensors, are currently or have been previously employed at universities or at other biotechnology or pharmaceutical companies, or may have previously provided or may be currently providing consulting services to other biopharmaceutical companies, including our competitors or potential competitors. These employees and consultants may have executed proprietary rights, non-disclosure and non-competition agreements, or similar agreements, in connection with such other current or previous employment. Although we, and likely Gilead and our licensors, try to ensure that our and their employees and consultants do not use the proprietary information or know-how of others in their work for us or them, we or they may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of third parties or former employers or former or current clients, or claims that we, Gilead, or our licensors have wrongfully hired an employee from a competitor. Litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property or personnel or sustain damages. Such intellectual property could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available on commercially reasonable terms or at all. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to our management. Any of the foregoing would have a material adverse effect on our business, financial condition, results of operations and prospects.
In addition, while it is our policy to require our employees, consultants and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property. Likewise, Gilead and our licensors may have been or may be unsuccessful in executing such an agreement with each party who conceived or developed intellectual property that we purchased or licensed, which may result in additional such claims by or against us. In addition, such agreements may not be self-executing such that the intellectual property subject to such agreements may not be assigned to us without additional assignments being executed, and we, Gilead, or our licensors may fail or may have failed to obtain such assignments. In addition, such agreements may be breached. Accordingly, we, Gilead, or our licensors may be forced to bring claims against third parties, or defend claims that they may bring against us, Gilead, or our licensors to determine the ownership of what we regard as our owned or licensed intellectual property. If we, Gilead, or our licensors fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our senior management and scientific personnel, which would have a material adverse effect on our business, financial condition, results of operations and prospects.
Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the term of a patent, and the protection it affords, is limited. In addition, the term of a patent may be reduced if a terminal disclaimer is or was filed in that patent, limiting the term of the patent to that of one or more other patents referenced in the terminal disclaimer. Even if patents directed to our product candidates are obtained, once the patent term has expired, we may be open to competition from competitive products. Given the amount of time required for the development, testing and regulatory review of product candidates, patents directed to our product candidates might expire before or shortly after such candidates are commercialized, and patent term extensions or other means of obtaining market exclusivity, such as data exclusivity, may not be available or adequately protective in countries where we market our products. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
90
If we or our licensors do not obtain patent term extension for our product candidates, our business may be materially harmed.
Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984 (the Hatch-Waxman Amendments). The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. A maximum of one patent may be extended per FDA-approved product as compensation for the patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. Patent term extension may also be available in certain foreign countries upon regulatory approval of our product candidates, but may not be available in other countries. However, we or our licensors may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we or our licensors are unable to obtain patent term extension or restoration or the term of any such extension is less than we request, our competitors may obtain approval of competing products following our patent expiration, and our revenue could be reduced, possibly materially. Further, if this occurs, our competitors may take advantage of our investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.
We may not be able to protect our intellectual property rights throughout the world.
Although we own or have acquired or in-licensed issued patents and have pending patent applications in the United States and certain other countries, filing, prosecuting and defending patents in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our technology in all countries outside the United States or from selling or importing products made using our technology in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we or our licensors have patent protection but enforcement is not as strong as that in the United States. These products may compete with our product candidates, and our or our licensors patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of many foreign countries do not favor the enforcement of patents and other intellectual property protection, which could make it difficult for us to stop the infringement of our or our licensors’ patents or marketing of competing products in violation of our proprietary rights. Proceedings to enforce our or our licensors’ patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our or our licensors’ patents at risk of being invalidated or interpreted narrowly, could put our or our licensors’ patent applications at risk of not issuing and could provoke third parties to assert claims against us. We or our licensors may not prevail in any lawsuits that we or our licensors initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our or our licensors’ efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.
Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patents. If we or our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected.
91
Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirements imposed by regulations and governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to the USPTO and various foreign patent offices at various points over the lifetime of our patents and/or applications. We have systems in place to remind us to pay these fees, and we rely on third parties to pay these fees when due. Additionally, the USPTO and various foreign patent offices require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with rules applicable to the particular jurisdiction. However, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If such an event were to occur, it could have a material adverse effect on our business.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
In addition, we rely on the protection of our trade secrets, including unpatented know-how, technology and other proprietary information to maintain our competitive position. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants, licensors and advisors, we cannot provide any assurances that all such agreements have been duly executed, and any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary information will be effective. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets.
Moreover, third parties may still obtain this information or may come upon this or similar information independently, and we would have no right to prevent them from using that technology or information to compete with us. If any of these events occurs or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced and our competitive position would be harmed. If we or our licensors do not apply for patent protection prior to such publication or if we cannot otherwise maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent protection or to protect our trade secret information may be jeopardized.
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.
Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names. Our efforts to enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely affect our business, financial condition, results of operations and prospects.

Risks Related to Our Reliance on Third Parties
We rely on third parties, including independent clinical investigators, developers of companion diagnostics, and CROs, to conduct certain aspects of our preclinical studies and ongoing and planned clinical trials. If these third parties do not successfully carry out their contractual duties, comply with applicable regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.
We have relied upon and plan to rely in the future upon third parties, including independent clinical investigators, developers of companion diagnostics, and CROs, to conduct certain aspects of our preclinical studies and ongoing and planned clinical trials and to monitor and manage data for our ongoing preclinical and planned clinical programs. Pursuant to the Gilead Asset Purchase Agreement, Gilead is responsible for certain ongoing clinical trials of entospletinib.
We rely or will rely on these parties for execution of our preclinical studies and ongoing and planned clinical trials, and may not control, or will only control certain aspects of, their activities. Nevertheless, we are or will be responsible for ensuring that each of our studies and trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on these third parties does not relieve us of our regulatory responsibilities. We and our third-party contractors and CROs are required to comply with GCP requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for all of our products candidates in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of these third parties or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. Moreover, our business may be adversely affected if any of these third parties violates federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.
Further, these investigators and CROs are not our employees and we will not be able to control, other than by contract, the amount of resources, including time, which they devote to our product candidates and clinical trials. These third parties may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other product development activities, which could affect their performance on our behalf. If independent investigators or CROs fail to devote sufficient resources to the development of our product candidates, or if CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. Additionally, they may undergo a change in control, which could extend, delay or terminate our clinical trials. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the duration of, or increase the size of any clinical trials we conduct. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed or precluded entirely.
We have CROs located in China and India. International tension or conflict with these countries could result in a material disruption in our contractual relationship with the CROs, which could delay or otherwise negatively impact progress in our preclinical programs. Our CROs have the right to terminate their agreements with us in the event of an uncured material breach, upon clinical trial subject safety concerns, or upon our insolvency.
The effects of the COVID-19 pandemic and government measures taken in response have also had a significant impact on our CROs, and they have in the past faced disruptions and in the future may face further disruption which may affect our ability to initiate and complete our preclinical studies and ongoing and planned clinical trials.
93
If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Additionally, CROs may lack the capacity to absorb higher workloads or take on additional capacity to support our needs. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.
We may form or seek collaborations or strategic alliances or enter into additional strategic arrangements in the future, which involve risks, and we may not realize the benefits of such collaborations, alliances or strategic arrangements.
We may form or seek strategic alliances, create joint ventures or collaborations, or enter into additional strategic arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to our product candidates and any future product candidates that we may develop. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-term expenditures, issue securities that dilute our existing stockholders or disrupt our management and business.
In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety, potency, purity and efficacy and obtain marketing approval. If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all.
Further, collaborations involving our product candidates are subject to numerous risks, which may include the following:
•collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration;
•collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew development or commercialization of our product candidates based on clinical trial results, changes in their strategic focus due to the acquisition of competitive products, availability of funding or other external factors, such as a business combination that diverts resources or creates competing priorities;
•collaborators may delay clinical trials, provide insufficient funding for a clinical trial, stop a clinical trial, abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
•collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates;
•a collaborator with marketing and distribution rights to one or more products may not commit sufficient resources to their marketing and distribution;
•collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;
94
•disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our product candidates, or that result in costly litigation or arbitration that diverts management attention and resources;
•collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable product candidates; and
•collaborators may own or co-own intellectual property covering our products that results from our collaborating with them, and in such cases, we would not have the exclusive right to commercialize such intellectual property. If we are unable to obtain exclusive licenses to any such co-owner’s interest in such intellectual property, such co-owner may be able to license their rights to third parties, including our competitors, and our competitors could market competing products and technology.
As a result, if we enter into collaboration agreements and strategic partnerships or license our product candidates, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. Any delays in entering into new collaborations or strategic partnership agreements related to our product candidates could delay the development and commercialization of our product candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations.
We will rely on third parties to manufacture our clinical product supplies, and we may rely on third parties to produce and process our product candidates, if approved.
We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We currently rely, and expect to continue to rely for the foreseeable future, on third parties for the manufacture of our product candidates for preclinical and clinical testing, as well as for commercial manufacture of any products that we may commercialize. In this regard, while we have purchased initial inventory of active pharmaceutical ingredients (APIs) and product candidates for entospletinib and lanraplenib from Gilead under the Gilead Asset Purchase Agreement, we will need to obtain further supplies of APIs and clinical drug supply for entospletinib, lanraplenib, and KB-0742, from third-party manufacturers. We do not currently have arrangements in place for redundant supply for APIs or our clinical product candidates. In addition, in the third quarter of 2020 we completed the transfer of the SYK technology we acquired from Gilead in July 2020, but we have not yet transferred the manufacturing technology for entospletinib or lanraplenib to a third-party manufacturer. We will need to arrange for the manufacture of these product candidates for use in clinical trials.
We will need to negotiate and maintain contractual arrangements with outside vendors for the supply of our future product candidates and we may not be able to do so on favorable terms. In addition, these third-party manufacturing providers may not be able to provide adequate resources or capacity to meet our needs. We expect to initially obtain our supplies from manufacturers on a purchase order basis without long-term supply arrangements in place We have not yet caused any product candidates to be manufactured on a commercial scale and may not be able to do so for any of our product candidates. In the future, we may be unable to enter into agreements with third-party manufacturers for commercial supplies of any product candidate, or may be unable to do so on acceptable terms.
Reliance on third-party manufacturers entails risks, including reliance on single sources for product components and lack of qualified backup suppliers for those components purchased from a sole or single source supplier. We cannot be sure that single source suppliers for our product components will remain in business or that they will not be purchased by one of our competitors or another company that is not interested in continuing to produce these components for our intended purpose. In addition, the lead time needed to establish a relationship with a new supplier can be lengthy, and we may experience delays in meeting demand in the event we must switch to a new supplier. The time and effort to qualify a new supplier could result in additional costs, diversion of resources or reduced manufacturing yields, any of which would negatively impact our operating results.
95
The facilities used by our contract manufacturers to manufacture our product candidates must be approved by the FDA or other foreign regulatory authorities following inspections that will be conducted after we submit an application to the FDA or other foreign regulatory authorities. We may not control the manufacturing process of, and may be completely dependent on, our contract manufacturing partners for compliance with cGMPs and any other regulatory requirements of the FDA or other regulatory authorities for the manufacture of our product candidates. Beyond periodic audits, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any approval in the future, we may need to find alternative manufacturing facilities, which would require the incurrence of significant additional costs and significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Similarly, if any third-party manufacturers on which we will rely fail to manufacture quantities of our product candidates at quality levels necessary to meet regulatory requirements and at a scale sufficient to meet anticipated demand at a cost that allows us to achieve profitability, our business, financial condition and prospects could be materially and adversely affected.
Manufacturing our product candidates is complex and we may encounter difficulties in production. If we encounter such difficulties, our ability to provide supply of our product candidates for preclinical studies and clinical trials or for commercial purposes could be delayed or stopped.
The process of manufacturing our product candidates is complex and highly regulated.
We expect to rely on third parties for the manufacture of our product candidates. These third-party manufacturers may incorporate their own proprietary processes into our product candidate manufacturing processes. We will have limited control and oversight of a third party’s proprietary process, and a third party may elect to modify its process without our consent or knowledge. These modifications could negatively impact our manufacturing, including product loss or failure that requires additional manufacturing runs or a change in manufacturer, both of which could significantly increase the cost of and significantly delay the manufacture of our product candidates.
As our product candidates progress through preclinical studies and clinical trials towards approval and commercialization, it is expected that various aspects of the manufacturing process will be altered in an effort to optimize processes and results. Such changes may require amendments to be made to regulatory applications which may further delay the timeframes under which modified manufacturing processes can be used for any of our product candidates and additional bridging studies or trials may be required.
In addition, in order to conduct clinical trials of our product candidates, we will need to have them manufactured in potentially large quantities. Our third-party manufacturers may be unable to successfully increase the manufacturing capacity for any of our clinical drug supplies (including key starting and intermediate materials) in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities and at any other time. If the third-party manufacturers are unable to successfully scale up the manufacture of our product candidates in sufficient quality and quantity, the development, testing and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial launch of that product candidate may be delayed or not obtained, which could significantly harm our business.
96
If our third-party manufacturers use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.
Our research and development activities involve the controlled use of potentially hazardous substances, including chemical and biological materials, by our third-party manufacturers. Our manufacturers are subject to federal, state and local laws and regulations in the United States governing the use, manufacture, storage, handling and disposal of medical and hazardous materials. Although we believe that our manufacturers’ procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury resulting from medical or hazardous materials. As a result of any such contamination or injury, we may incur liability or local, city, state or federal authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources. We do not have any insurance for liabilities arising from medical or hazardous materials. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development and production efforts, which could harm our business, prospects, financial condition or results of operations.
Risks Related to Managing Our Growth, Employee Matters and Other Risks
Our success is highly dependent on our ability to attract and retain highly skilled executive officers and employees.
To succeed, we must recruit, retain, manage and motivate qualified clinical, scientific, technical and management personnel, and we face significant competition for experienced personnel. We are highly dependent on the principal members of our management and scientific and medical staff. If we do not succeed in attracting and retaining qualified personnel, particularly at the management level, it could adversely affect our ability to execute our business plan and harm our operating results. In particular, the loss of one or more of our executive officers could be detrimental to us if we cannot recruit suitable replacements in a timely manner. The competition for qualified personnel in the biotechnology field is intense and as a result, we may be unable to continue to attract and retain qualified personnel necessary for the future success of our business. We could in the future have difficulty attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention efforts.
Many of the other biotechnology companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better prospects for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel, the rate and success at which we can discover, develop and commercialize our product candidates will be limited and the potential for successfully growing our business will be harmed.
We have grown rapidly and will need to continue to grow the size of our organization and expand our capabilities, and we may experience difficulties in managing this growth.
As of December 31, 2021, we had 96 full-time employees. As of January 1, 2019, we had nine full-time employees and since then, we have expanded our executive and leadership team with the additions of our Chief Medical Officer and Executive Vice President, Clinical Development, our Chief Scientific Officer, our Chief Operating Officer and General Counsel, our Chief Financial Officer, our Senior Vice President, Pharmaceutical Development and Manufacturing, our Senior Vice President, Corporate Communications and Investor Relations, and our Senior Vice President of Clinical Development. We expect to experience continued growth in the number of our employees and the scope of our operations, particularly in the areas of clinical development, research science, clinical operations, manufacturing, regulatory affairs, and, if any of our product candidates receives marketing approval, sales, marketing and distribution. In addition, we are building a self-sufficient accounting and finance group within our company, and have relied and continue to rely on a third-party accounting consulting firm to augment our internal accounting and finance function. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel.
97
Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth and with building clinical development, manufacturing and internal accounting and finance infrastructure, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources.
Further, we currently rely, and for the foreseeable future will continue to rely, in substantial part on certain third-party contract organizations, advisors and consultants to provide certain services, including assuming substantial responsibilities for the conduct of our ongoing and planned clinical trials and the manufacture of our current or future product candidates. We cannot be certain that the services of such third-party contract organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by our vendors or consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain marketing approval of any of our product candidates or otherwise advance our business. We cannot assure you that we will be able to properly manage our existing vendors or consultants or find other competent outside vendors and consultants on economically reasonable terms, or at all.
If we are not able to effectively manage growth and expand our organization, we may not be able to successfully implement the tasks necessary to further develop and commercialize entospletinib, lanraplenib, KB-0742, our other pipeline product candidates or any future product candidates and, accordingly, may not achieve our research, development and commercialization goals.
Our information technology systems, or those used by our third-party CROs or other contractors or consultants, may fail, be disrupted or suffer security breaches, which could result in a material disruption of our discovery and development programs or otherwise materially and adversely affect our business.
Despite the implementation of security measures, our internal computer systems and those of our current and future CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, and telecommunication and electrical failures. If such an event occurs and causes interruptions in our operations, it could result in a material disruption of our discovery and development programs and our business operations. For example, the loss of data from completed or future preclinical studies and clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties for the manufacture of our product candidates and will rely on third parties to conduct our clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business.
To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our product candidates could be delayed.
If our information technology systems or data is or were compromised, we could experience adverse impacts resulting from such compromise, including, but not limited to, interruptions to our operations such as our clinical trials, claims that we breached our data protection obligations, harm to our reputation, and a loss of customers or sales.
In the ordinary course of business, we collect, store, transmit or otherwise process proprietary, confidential, and sensitive data (including but not limited to intellectual property, proprietary business information and personal data). We have also outsourced elements of our operations to third parties, and as a result we rely on a number of third-party contractors who have access to our proprietary, confidential, and sensitive data. We may share or receive sensitive data with or from third parties. Our ability to monitor these third parties’ cybersecurity practices is limited, and these third parties may not have adequate information security measures in place.
Cyberattacks, malicious internet-based activity, and online and offline fraud are prevalent and continue to increase. These threats are becoming increasingly difficult to detect. These threats come from a variety of sources. In addition to traditional computer “hackers,” threat actors, personnel misconduct or error (such as theft or misuse), sophisticated nation-state and nation-state supported actors now engage in attacks. We may be subject to a variety of evolving threats, including but not limited to social engineering attacks (including through phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced
98
persistent threat intrusions), denial-of-service attacks (such as credential stuffing), ransomware attacks, supply-chain attacks, software bugs, server malfunction, software or hardware failures, loss of data or other information technology assets, adware, telecommunications failures, earthquakes, fire, flood, and other similar threats. Ransomware attacks, including those perpetrated by organized criminal threat actors, nation-states, and nation-state supported actors, are becoming increasingly prevalent and severe and can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting payments. Similarly, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties and infrastructure in our supply chain have not been compromised or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our information technology systems or the third-party information technology systems that support us. The COVID-19 pandemic and our remote workforce poses increased risks to our information technology systems and data, as more of our employees work from home, utilizing network connections outside our premises.
Any of the previously identified or similar threats could cause a security incident. A security incident could result in unauthorized, unlawful or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of or access to data. A security incident could disrupt our (and third parties upon whom we rely) ability to provide our products. Certain of our vendors have previously experienced specific instances of cyber events, including email compromise and wire fraud targeting payments to be made by us.
We may expend significant resources or modify our business activities (including our clinical trial activities) in an effort to protect against security incidents. Certain data privacy and security obligations may require us to implement and maintain specific security measures, industry-standard or reasonable security measures to protect our information technology systems and data. While we have implemented security measures designed to protect against a security incident, there can be no assurance that these measures will be effective. We have not always been able in the past and may be unable in the future to detect vulnerabilities in our information technology systems (including our products) because such threats and techniques change frequently, are often sophisticated in nature, and may not be detected until after a security incident has occurred. Despite our efforts to identify and remediate vulnerabilities, if any, in our information technology systems, our efforts may not be successful. Further, we may experience delays in developing and deploying remedial measures designed to address any such identified vulnerabilities.
Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents. Such disclosures are costly, and the disclosures or the failure to comply with such requirements, could lead to adverse impacts. If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences. These consequences may include: government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing data (including personal data); litigation (including class claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; interruptions in our operations (including availability of data); financial loss; and other similar harms. Security incidents and attendant consequences may cause customers to stop using our products, deter new customers for using products, and negatively impact our ability to grow and operate our business. There can be no assurance that limitations of liability in our contracts are sufficient to protect us from claims related to our data security obligations.
99
Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.
Our operations, and those of our CROs, contract manufacturing organizations (CMOs) and other contractors and consultants, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, epidemics and pandemics such as the COVID-19 pandemic, and other natural or man-made disasters or business interruptions, for which we are predominantly self-insured. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. We rely on third-party manufacturers to produce our product candidates. Our ability to obtain clinical supplies of our product candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption.
Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
Under current law, federal net operating losses incurred in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal net operating losses in tax years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to federal tax law. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change” (generally defined as a greater than 50 percentage point change (by value) in the equity ownership of certain stockholders over a rolling three-year period), the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income and taxes may be limited. As a result of our private placements and other transactions that have occurred over the past three years, including our IPO, which we completed in October 2020, we may have experienced, an “ownership change.” We may also experience ownership changes in the future as a result of subsequent issuances of our common stock or other shifts in our stock ownership. We anticipate incurring significant additional net losses for the foreseeable future, and our ability to utilize net operating loss carryforwards associated with any such losses to offset future taxable income may be limited to the extent we incur future ownership changes. In addition, at the state level, there may be periods during which the use of net operating loss carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, we may be unable to use all or a material portion of our net operating loss carryforwards and other tax attributes, which could adversely affect our future cash flows.
Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.
As widely reported, global credit and financial markets have experienced extreme volatility and disruptions in the past several years, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions, will not occur. Our general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, or do not improve, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive.
Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive these difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget.
Our stock price may decline due in part to the volatility of the stock market and any general economic downturn.
100
Risks Related to Our Common Stock
Provisions in our corporate charter documents and under Delaware law could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.
Provisions of our amended and restated certificate of incorporation and amended and restated bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our amended and restated certificate of incorporation and amended and restated bylaws:
•permit our board of directors to issue up to 10,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate (including the right to approve an acquisition or other change in our control);
•provide that the authorized number of directors may be changed only by resolution of the board of directors;
•provide that our board of directors or any individual director may only be removed with cause and the affirmative vote of the holders of at least 66-2/3% of the voting power of all of our then-outstanding common stock;
•provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;
•divide our board of directors into three classes;
•require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent;
•provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and also specify requirements as to the form and content of a stockholder’s notice;
•do not provide for cumulative voting rights (therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose);
•provide that special meetings of our stockholders may be called only by the chair of our board of directors, our Chief Executive Officer or by the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors; and
101
•provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or other employees to us or our stockholders; (iii) any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees, arising out of or pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws; (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or our bylaws; (v) any action or proceeding as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any action asserting a claim against us or any of our directors, officers or other employees governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants; provided these provisions of our amended and restated certificate of incorporation and amended and restated bylaws will not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended (Exchange Act), or any other claim for which the federal courts have exclusive jurisdiction; and provided that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (Securities Act).
The amendment of any of these provisions, with the exception of the ability of our board of directors to issue shares of preferred stock and designate any rights, preferences and privileges thereto, would require approval by the holders of at least 66-2/3% of our then-outstanding common stock.
In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time. A Delaware corporation may opt out of this provision by express provision in its original certificate of incorporation or by amendment to its certificate of incorporation or bylaws approved by its stockholders. However, we have not opted out of this provision.
These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it more difficult for stockholders or potential acquirors to obtain control of our board of directors or initiate actions that are opposed by our then-current board of directors, including delay or impede a merger, tender offer or proxy contest involving our company.
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.
Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants, the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:
•any derivative action or proceeding brought on our behalf;
•any action or proceeding asserting a breach of fiduciary duty owed by any of our current or former directors, officers or other employees to us or our stockholders;
•any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees arising out of or pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or bylaws;
•any action or proceeding to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws;
•any action or proceeding as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; and
102
•any action asserting a claim against us or any of our directors, officers or other employees that is governed by the internal affairs doctrine.
This provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated certificate of incorporation further provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.
These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.
The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses for purchasers of our common stock.
Our stock price is likely to be volatile. The stock market in general and the market for smaller biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price for our common stock may be influenced by many factors, including:
•the degree of success of competitive products or technologies;
•the commencement, enrollment or results of clinical trials and preclinical studies of our product candidates or those of our competitors;
•adverse results from, delays in or termination of clinical trials;
•unanticipated serious safety concerns related to the use of our product candidates;
•regulatory or legal developments in the United States and other countries;
•any delay in our regulatory filings for our product candidates and any adverse development or perceived adverse development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information;
•receipt of, or failure to obtain, regulatory approvals;
•changes in the structure of healthcare payment systems;
•lower than expected market acceptance of our product candidates following approval, if any, for commercialization;
•developments or disputes concerning patent applications, issued patents or other proprietary rights;
•the recruitment or departure of key personnel;
•the level of expenses related to any of our product candidates or clinical development programs;
•the results of our efforts to develop, acquire or in-license additional technologies or product candidates;
103
•actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;
•publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by securities analysts;
•announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;
•variations in our financial results or those of companies that are perceived to be similar to us;
•rumors or announcements regarding transactions involving our company or product candidates;
•proposed changes to healthcare laws in the United States or foreign jurisdictions, or speculation regarding such changes;
•market conditions or trends in the pharmaceutical and biotechnology sectors;
•the societal and economic impact of public health epidemics, such as the ongoing COVID-19 pandemic;
•general economic, industry and market conditions; and
•the other events or factors, including those described in this “Risk Factors” section.
Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.
Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock.
Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
We designed our disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make any related party transaction disclosures. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.
Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be the sole source of gain for our stockholders.
We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the terms of any future debt agreements we may enter into may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for our stockholders for the foreseeable future.
We could be subject to securities class action litigation.
In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because pharmaceutical companies have experienced significant stock price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.
104
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about us, our business or our market, our stock price and trading volume could decline.
The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not control these analysts or the content and opinions or financial models included in their reports. If additional securities analysts do not provide research coverage of our company, or if analysts cease coverage of us, the trading price for our common stock could be negatively affected. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our common stock price and trading volume to decline.
General Risk Factors
An active trading market for our common stock may not be sustained.
Although our common stock is listed on the Nasdaq Global Select Market, an active trading market for our shares may not be sustained. If an active market for our stock does not continue, it may be difficult for our stockholders to sell their shares without depressing the market price for the shares or to sell their shares at all. An inactive trading market for our common stock may also impair our ability to raise capital to continue to fund our operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.
We incur substantial costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives and corporate governance practices.
As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Global Select Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and will make some activities more time-consuming and costly.
ITEM 1B. UNRESOLVED STAFF COMMENTS
None.
ITEM 2. PROPERTIES
Our corporate headquarters are located in San Mateo, California, where we lease office space pursuant to a lease agreement which commenced on August 1, 2018. On February 8, 2021, we amended our lease agreement and, on July 1, 2021, we relocated to a larger area in the same building comprising approximately 17,340 square feet of office space. The amendment extended the expiration date of the lease from April 30, 2025 to the earlier of the last day of the 60th calendar month following the commencement of the relocation or August 31, 2026. We also lease approximately 40,514 square feet of office and laboratory space in Cambridge, Massachusetts pursuant to a lease agreement which was entered into on February 28, 2020 and expires on February 28, 2031. We have completed the build out of this facility, which we began to occupy on November 24, 2020. We believe that our existing facilities are adequate for the foreseeable future. As we expand, we believe that suitable additional alternative spaces will be available in the future on commercially reasonable terms, if required.
ITEM 3. LEGAL PROCEEDINGS
From time to time, we may become involved in litigation or other legal proceedings. While the outcome of any such proceedings cannot be predicted with certainty, as of December 31, 2021, we were not a party to any litigation or legal proceedings that, in the opinion of our management, are probably to have a material effect on our business.

Use of Proceeds from our Initial Public Offering of Common Stock
In October 2020, we completed our initial public offering, pursuant to which we sold 15,131,579 shares of our common stock at a price to the public of $19.00 per share, including 1,973,684 shares sold pursuant to the full exercise of the underwriters’ option to purchase additional shares. The shares were registered pursuant to a registration statement on Form S-1 (File No. 333-248925) that was declared effective on October 8, 2020. As a result of our IPO, we raised a total of approximately $263.7 million in net proceeds after deducting underwriting discounts and commissions of $20.1 million and offering expenses of approximately $3.7 million. Goldman Sachs & Co. LLC, Jefferies LLC, Cowen and Company, LLC and Piper Sandler & Co. acted as joint book-running managers for our IPO.
Upon receipt, the net proceeds from our IPO were held in cash, cash equivalents and investments. As of December 31, 2021, we have not used any of the net proceeds from our IPO.
We expect to use the net proceeds from our IPO as described under “Use of Proceeds” in the final prospectus for the IPO, as filed with the SEC on October 9, 2020. We cannot predict with certainty all of the particular uses for the net proceeds from our IPO, or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds will vary depending on numerous factors, including our ability to access additional financing, the relative success and cost of our research, preclinical and clinical development programs and whether we are able to enter into future licensing arrangements. As a result, our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds from our IPO.
ITEM 6. [Reserved]
ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis should be read in conjunction with our financial statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that reflect our plans, estimates and beliefs and involve numerous risks and uncertainties, including but not limited to those described in the “Risk Factors” section of this Annual Report. Actual results may differ materially from those contained in any forward-looking statements. You should carefully read “Forward-Looking Statements” and “Risk Factors.”
Overview
We are an integrated discovery through late-stage clinical development biopharmaceutical company, with a focus on developing therapeutics that target the dysregulated transcription that causes cancer and other serious diseases. We have two investigational compounds in clinical trials, including one in a pivotal Phase 3 trial, and a third compound that we anticipate will enter the clinic in the first quarter of 2022. Our product engine, which includes our propriety small molecule microarray (SMM) screening platform, provides us with the capability to map and target transcription regulatory networks (TRNs) in a differentiated manner to enable discovery of novel compounds and improve our translational capabilities.
Our lead product candidate, entospletinib, is an orally administered, selective spleen tyrosine kinase (SYK) inhibitor that has been previously tested in more than 1,300 people, including more than 200 patients with acute
108
myeloid leukemia (AML). Based on clinical results in a biomarker-defined subset of patients and following recent discussions as part of an End-of-Phase 2 meeting with the FDA, we have initiated our randomized, double-blinded, placebo-controlled registrational Phase 3 AGILITY clinical trial of entospletinib in combination with intensive chemotherapy in approximately 180 patients with newly diagnosed NPM1-mutated AML. We are also developing lanraplenib, our next-generation orally-administered SYK inhibitor, and plan to initiate a Phase 1b/2 clinical trial in the first quarter of 2022. This clinical trial will evaluate lanraplenib in combination with gilteritinib in patients with relapsed or refractory FLT3-mutated AML. In addition, we are developing KB-0742, our internally discovered, oral cyclin dependent kinase 9 inhibitor (CDK9), for the treatment of MYC-amplified and other transcriptionally addicted solid tumors. The first patient in our Phase 1/2 clinical trial was dosed in February 2021, and we reported initial data in the fourth quarter of 2021. In our research efforts, we are leveraging our product engine to drive multiple oncology discovery programs targeting dysregulated transcription factors and their associated TRNs. In November 2021, we announced the advancement of two programs, one focused on the MYC TRN and one focused on the androgen receptor (AR) TRN, based on this work.
We also are executing on robust discovery programs across multiple TRNs, which focus on four cancer types where dysregulated transcription plays a central role: hematologic malignancies, prostate cancer, MYC-driven cancers, and small cell/neuroendocrine cancers. We anticipate submitting an IND for a drug candidate arising from one of these programs in 2023, although we may not be successful in identifying product candidates that can selectively modulate the specific oncogenic TRNs associated with these malignancies.
The following chart summarizes the current stages of our development programs, including our lead product candidate, entospletinib, as well as lanraplenib KB-0742, and our next anticipated milestones
The ongoing COVID-19 pandemic has presented substantial public health and economic challenges around the world. We cannot at this time predict the specific extent, duration or impact that COVID-19 will have on our financial condition and operations, including ongoing research activities, ongoing and planned clinical trials and our financial results. While we are currently conducting a pivotal Phase 3 clinical trial for entospetinib, a Phase 1/2 clinical trial for KB-0742 and are preparing to initiate an additional clinical trial in the first quarter of 2022, COVID-19 precautions may directly or indirectly impact their timelines and interrupt clinical enrollment.
Since our formation in June 2017, we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, identifying, acquiring and developing our product candidates, building our product engine, establishing our intellectual property portfolio, and providing general and administrative support for these operations. We have principally financed our operations to date through our IPO, and, before that, private placements of our convertible preferred stock and convertible notes.
109
Since our formation, we have incurred significant operating losses, primarily from costs incurred in connection with research and development activities and general and administrative costs associated with our operations. Our net losses were $151.1 million, $88.4 million, and $16.1 million for the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021 and 2020, we had an accumulated deficit of $263.0 million and $111.9 million, respectively. As of December 31, 2021 and 2020, we had $339.5 million and $462.1 million of cash, cash equivalents and investments, respectively. We expect to continue to incur net losses for the foreseeable future, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase.
110
Strategic Agreements
Tempus R&D Services Agreement
In October 2021, we entered into an agreement for research and development services (Tempus Agreement) with Tempus Labs, Inc. (Tempus), pursuant to which Tempus has agreed to provide us with research and development services for a period of three years. The three primary services are analytical services, data licensing, and organoid services. We intend to utilize the services contemplated under the Tempus Agreement to advance the development of KB-0742 and lanraplenib.
In consideration for the access to the services throughout the term of the Tempus Agreement, we have agreed to pay an annual minimum commitment of $1.5 million in year one, $2.0 million in year two, and $2.5 million in year three. Payments are made in quarterly installments. As of December 31, 2021, we have not made any payments under the Tempus Agreement.
In addition, we are required to make milestone payments upon successful achievement of certain regulatory milestones for KB-0742, lanraplenib, and other discovery pipeline compounds up to a combined maximum of $22.4 million. For each milestone payment that becomes due, we have the right to pay up to 50% of such milestone payment amount in shares of our common stock as long as certain regulatory requirements are met.
Gilead Asset Purchase Agreement
In July 2020, we entered into the Gilead Asset Purchase Agreement, pursuant to which we acquired certain assets from Gilead related to entospletinib and lanraplenib, and patents and other intellectual property covering or related to the development, manufacture and commercialization of entospletinib and lanraplenib.
In consideration for such assets, on the date of the Gilead Asset Purchase Agreement, we made a $3.0 million upfront cash payment and issued a $3.0 million principal amount convertible promissory note to Gilead (Gilead Note). We also made a $0.7 million payment to reimburse Gilead for certain liabilities we assumed pursuant to the Gilead Asset Purchase Agreement. In addition, we are required to make milestone payments upon successful achievement of certain regulatory and sales milestones for entospletinib, lanraplenib and other SYK inhibitor compounds covered by the patent rights acquired pursuant to the Gilead Asset Purchase Agreement and developed by us as a back-up to entospletinib or lanraplenib (Other Compounds). Upon initiation of our registrational Phase 3 clinical trial of entospletinib in combination with induction chemotherapy in acute myeloid leukemia patients with NPM1 mutations in December 2021, we paid a milestone to Gilead of $29.0 million. Upon successful completion of certain other regulatory milestones in the United States, European Union and United Kingdom for entospletinib, lanraplenib and any Other Compounds, across up to two distinct indications, we will be required to pay to Gilead an aggregate total of $51.3 million. Upon achieving certain thresholds for the aggregate annual net sales of entospletinib, lanraplenib and any Other Compounds combined, we would owe to Gilead potential milestone payments totaling $115.0 million.
Gilead is also eligible to receive (i) tiered marginal royalties ranging from the very low-teens to high-teens on annual worldwide net sales of entospletinib, (ii) tiered marginal royalties ranging from high-single digits to the mid-teens on annual worldwide net sales of lanraplenib and (iii) tiered marginal royalties ranging from the low single digits to mid-single digits on annual worldwide net sales of any Other Compounds. The royalties in the foregoing clauses are subject to reduction, on a country-by-country basis, for products not covered by certain claims within the assigned patents, for generic entry and, in the case of entospletinib and lanraplenib, for any royalties paid for future licenses of third party intellectual property required to develop or commercialize entospletinib or lanraplenib. Our royalty obligation with respect to a given product in a given country begins upon the first commercial sale of such product in such country and ends on the latest of (i) expiration of the last claim of a defined set of the assigned patent rights covering such product in such country; (ii) loss of exclusive data or marketing rights to such product in such country; or (iii) 10 years from the first commercial sale of such product in such country.
Under the Gilead Asset Purchase Agreement, we are required to use commercially reasonable efforts to develop, obtain regulatory approval for and commercialize either entospletinib or lanraplenib.
111
Harvard License Agreement
In January 2018, we entered into a license agreement with President and Fellows of Harvard College (Harvard), pursuant to which Harvard granted us a non-exclusive, worldwide, royalty-free license to certain intellectual property for the purpose of commercializing products relating to our SMM platform. We paid a one-time license fee in the amount of $10,000 on the date of the agreement, an annual license maintenance fee of $20,000 on each of the first two anniversaries and an annual license fee of $25,000 on each subsequent anniversary until the last to expire of any valid claim included in the licensed patents.
112
Components of Our Results of Operations
Operating Expenses
Our operating expenses consisted of research and development expenses and general and administrative expenses.
Research and Development Expenses
Our research and development expenses consist primarily of direct and indirect costs incurred in connection with our therapeutic discovery efforts and the preclinical and clinical development of our product candidates, as well as the development of our product engine.
Direct costs include:
•expenses incurred under agreements with contract research organizations (CROs) and other vendors that conduct our clinical trials and preclinical activities;
•costs of outside consultants, including their fees, stock-based compensation and related travel expenses;
•costs of acquiring, developing, and manufacturing clinical trial materials and lab supplies; and
•payments made under third-party strategic agreements.
Indirect costs include:
•personnel costs, which include salaries, benefits, and other employee related costs, including stock-based compensation, for personnel engaged in research and development functions;
•costs related to compliance with regulatory requirements; and
•facilities costs, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies.
We expense research and development costs as the services are performed or the goods are received. We recognize costs for certain development activities based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors and our internal management. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid or accrued research and development expenses.
Because we are working on multiple research and development programs at any one time, we intend to track our direct costs by the stage of program, clinical or preclinical. However, our internal costs, employees and infrastructure are not directly tied to any one program and are deployed across multiple programs. As such, we do not track indirect costs on a specific program basis.
Our research and development expenses may vary significantly based on a variety of factors, such as:
•the scope, rate of progress, expense and results of our preclinical development activities;
•per patient trial costs;
•the number of trials required for approval; the number of sites included in the trials;
•the number of patients that participate in the trials;
•the countries in which the trials are conducted;
•uncertainties in clinical trial design and patient enrollment or drop out or discontinuation rates, particularly in light of the current COVID-19 pandemic environment;
•potential additional safety monitoring requested by regulatory agencies;
•the duration of patient participation in the trials and follow-up;
113
•the safety and efficacy of our product candidates;
•the timing, receipt, and terms of any approvals from applicable regulatory authorities including the FDA and non-U.S. regulators;
•significant and changing government regulation and regulatory guidance;
•potential additional trials requested by regulatory agencies;
•establishing clinical and commercial manufacturing capabilities or making arrangements with third-party manufacturers in order to ensure that we or our third-party manufacturers are able to make product successfully;
•the extent to which we establish additional strategic collaborations or other arrangements;
•the impact of any business interruptions to our operations or to those of the third parties with whom we work, particularly in light of the current COVID-19 pandemic environment;
•the expense of filing, prosecuting, defending, and enforcing any patent claims and other intellectual property rights; and
•maintaining a continued acceptable safety profile of our product candidates following approval, if any, of our product candidates.
A change in the outcome of any of these variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate.
We expect that our research and development expenses will continue to increase substantially for the foreseeable future as we continue to identify and develop additional product candidates and as more of our product candidates move into later stages of clinical development, which typically have higher development costs than those in earlier stages of clinical development due to the increased size and duration of later-stage clinical trials.
The process of conducting the necessary preclinical and clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidates may be affected by a variety of factors. We may never succeed in achieving regulatory approval for any of our product candidates. Further, a number of factors, including those outside of our control, could adversely impact the timing and duration of our product candidates’ development, which could increase our research and development expenses.
General and Administrative Expenses
General and administrative expenses consist primarily of personnel costs, which include salaries, benefits and other employee related costs, such as stock-based compensation, for personnel in our executive, finance, corporate and business development, and administrative functions. General and administrative expenses also include legal fees relating to patent and corporate matters; professional fees for accounting, auditing, tax and consulting services; insurance costs; recruiting costs; travel expenses; and facilities-related costs.
We expect that our general and administrative expenses will continue to increase substantially for the foreseeable future as we continue to increase our general and administrative personnel headcount to support personnel in research and development, and to support our operations generally as we increase our research and development activities and activities related to the potential commercialization of our product candidates. We also expect to incur increased expenses associated with operating as a public company, including costs of accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance costs, and investor and public relations costs.

We elected on issuance to account for our convertible notes payable (2020 Notes and Gilead Note) at fair value until their settlement. The change in fair value of our convertible notes payable was recognized through the statement of operations and comprehensive loss. The 2020 Notes and the Gilead Note settled on the closing of our IPO in October 2020.
Interest Expense
Interest expense consists of debt issuance costs we incurred to issue the 2020 Notes. The debt issuance costs were expensed on issuance because we elected to record the 2020 Notes at fair value.
Interest and Other Income, Net
Interest and other income, net primarily consists of interest earned on our cash, cash equivalents and investments.

Research and development expenses were $112.9 million for the year ended December 31, 2021, compared to $43.3 million for the year ended December 31, 2020. The increase of $69.7 million was primarily due to an increase of $48.5 million in outside and consulting research expenses, which includes the $29.0 million milestone payment in the fourth quarter of 2021 related to the Gilead Asset Purchase Agreement (See Note 13). Also contributing to this increase in research and development expenses is an increase in personnel costs of $7.7 million and an increase in stock-based compensation of $11.8 million, both of which are primarily attributable to increased research and development personnel headcount, and an increase of $1.1 million in lab supplies related to increased development activity in connection with our preclinical product candidates.
Research and development expenses were $43.3 million for the year ended December 31, 2020, compared to $13.5 million for the year ended December 31, 2019. The increase of $29.8 million was primarily due to $6.6 million in acquisition costs for our SYK portfolio related to the Gilead Asset Purchase Agreement (See Note 13), an increase of $9.9 million in outside and consulting research expenses, and an increase of $8.7 million in personnel costs primarily attributable to increased research and development personnel headcount, including an increase in stock-based compensation of $1.3 million. Also contributing to this increase in research and development expenses is an increase of $3.4 million in facilities, depreciation and other expenses primarily attributable to the commencement of the lease for our new Cambridge facility (as described below) in March 2020, and an increase of $1.2 million in lab supplies related to increased development activity in connection with our preclinical product candidates.
General and Administrative Expenses
General and administrative expenses were $38.5 million for the year ended December 31, 2021 compared to $14.8 million for the year ended December 31, 2020. The increase of $23.7 million was primarily due to an increase in stock-based compensation of $10.7 million and an increase of $3.8 million in personnel costs, both of which are primarily attributable to increased general and administrative personnel headcount to support the growth of our research and development organization. Also contributing to this increase in general and administrative expenses is an increase of $7.5 million in professional fees, primarily attributable to legal and outside consultant costs, an increase of $1.0 million in facilities, depreciation and other expenses primarily attributable to the San Mateo facility, and an increase of $0.7 million in other expenses primarily attributable to increases in taxes and filing fees, facility costs, and information technology related services.
General and administrative expenses were $14.8 million for the year ended December 31, 2020 compared to $3.4 million for the year ended December 31, 2019. The increase of $11.4 million was primarily due to an increase of $2.2 million in personnel costs, primarily attributable to increased general and administrative personnel headcount to support the growth of our research and development organization, a $3.9 million increase in professional fees primarily attributable to legal, insurance, and outside consultant costs, and a $3.0 million increase in other expenses primarily attributable to facility costs, employee onboarding costs, and taxes and filing fees. Also contributing to this increase in general and administrative expenses is an increase in stock-based compensation of $2.3 million attributable to both the increases in personnel costs and outside consulting services.
Change in Fair Value of Convertible Notes Payable
The change in fair value of convertible notes payable of $27.4 million for the year ended December 31, 2020 was directly attributable to our issuance and settlement of the 2020 Notes and the Gilead Note. There were no similar transactions in the years ended December 31, 2021 and 2019.
Interest Expense
Interest expense of $3.9 million for the year ended December 31, 2020 consists of debt issuance costs that were expensed on issuance of the 2020 Notes. There were no similar material transactions in the years ended December 31, 2021 and 2019.
Interest and Other Income, Net
Interest and other income, net was $0.3 million and $0.9 million for the years ended December 31, 2021 and 2020, respectively. The $0.6 million decrease was due to a lower interest earning balance and lower interest rates during the twelve months ended December 31, 2021.
116
Interest and other income, net was $0.9 million and $0.7 million for the years ended December 31, 2020 and 2019, respectively. The $0.2 million increase was due to interest earned on our cash equivalents and investments as our combined cash, cash equivalents and investments interest earning balance was higher during the twelve months ended December 31, 2020.
Liquidity and Capital Resources
Sources of Liquidity
To date, we have incurred significant operating losses and negative cash flows from operations. We have not yet commercialized any products and we do not expect to generate revenue from sales of any product candidates for several years, if ever. Prior to our IPO, our operations were financed primarily by net proceeds from the sale and issuance of our convertible preferred stock and convertible notes, totaling aggregate gross proceeds of $278.2 million. Upon completion of our IPO on October 14, 2020, we sold an aggregate of 15,131,579 shares of our common stock including 1,973,684 shares of common stock sold pursuant to the full exercise of the underwriters’ option to purchase additional shares at a price of $19.00 per share and received approximately $263.7 million in net proceeds after deducting underwriting discounts and commissions and offering expenses.
As of December 31, 2021, we had cash, cash equivalents and investments of $339.5 million. We expect that our cash, cash equivalents and investments as of December 31, 2021, will enable us to fund our planned operating expenses and capital expenditure requirements into the second half of 2024.
Material Cash Requirements
Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to entospletinib, lanraplenib and KB-0742, and our other research efforts, and to a lesser extent, general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.
Our product candidates are still in the early stages of clinical and preclinical development, and the outcomes of these efforts are uncertain. Accordingly, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidates or whether, or when, we may achieve profitability. Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity or debt financings and collaboration agreements. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our existing stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we are unable to raise capital when needed, we will need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

Operating Activities
During the year ended December 31, 2021, cash used in operating activities was $117.9 million, which was primarily attributable to our net loss of $151.1 million, partially offset by non-cash charges of $34.8 million. The non-cash charges primarily consisted of $26.2 million in stock-based compensation, net amortization and accretion of investment securities of $4.0 million, noncash lease expense of $2.1 million, depreciation and amortization of $2.0 million, and cash used by changes in our operating assets and liabilities of $1.6 million. Net cash used by changes in our operating assets and liabilities of $1.6 million during the year ended December 31, 2021 consisted of a decrease of $2.3 million in other liabilities and a decrease of $1.0 million in prepaid and other current assets partially offset by an increase in accounts payable and accrued expenses of $1.6 million and an increase of $0.1 million in other assets. The decrease in other liabilities was primarily the result of an decrease in the unvested early exercised share liability. The increase in accounts payable and accrued expenses was largely due to increases in accrued compensation and external research and development costs.
During the year ended December 31, 2020, cash used in operating activities was $37.9 million, which was primarily attributable to our net loss of $88.4 million, partially offset by non-cash charges of $44.1 million and cash provided by changes in our operating assets and liabilities of $6.5 million. Net cash provided by changes in our operating assets and liabilities of $6.5 million during the year ended December 31, 2020 consisted of an increase of accounts payable and accrued expenses $6.0 million and an increase of $4.7 million in other liabilities, partially offset by an increase of $5.2 million in prepaid and other current assets. The increase in accounts payable and accrued expenses was largely due to increases in accrued compensation and external research and development costs and the increase in other liabilities was primarily the result of an increase in the unvested early exercised share liability. The increase in prepaid and other current assets was primarily due to increases in prepaid insurance and external research and development and outside services.
During the year ended December 31, 2019, cash used in operating activities was $15.1 million, which was primarily attributable to our net loss of $16.1 million, partially offset by non-cash charges of $0.8 million and cash provided by changes in our operating assets and liabilities of $0.3 million. Net cash provided by changes in our operating assets and liabilities of $0.3 million during the year ended December 31, 2019 consisted of an increase of $1.3 million in accounts payable and accrued expenses as well as a decrease of $0.2 million related to other long-term assets, partially offset by an increase of $0.6 million in prepaid expenses and other current assets and a decrease of $0.2 million in other liabilities. The increase in accounts payable and accrued expenses was largely due to an increase in external research and development costs. The increase in prepaid expenses and other current assets was due to interest earned on available-for-sale securities.
Investing Activities
During the year ended December 31, 2021, cash provided by investing activities was $63.7 million, consisting of $226.2 million in maturities of marketable securities, partially offset by net investment purchases of $158.3 million and $4.3 million for the purchase of property and equipment.
During the year ended December 31, 2020, cash used in investing activities was $160.2 million, consisting of $78.7 million in cash received from investment maturities, offset by $229.3 million of net investment purchases and $9.6 million for the purchase of property and equipment.
118
During the year ended December 31, 2019, cash used in investing activities was $67.6 million, consisting of $64.6 million of net investment purchases and $2.9 million for the purchase of property and equipment.
Financing Activities
During the year ended December 31, 2021, net cash provided by financing activities was $4.5 million, consisting primarily of net proceeds from the exercise of stock options and issuance of common stock under the employee stock purchase plan of $3.1 million and $1.3 million, respectively.
During the year ended December 31, 2020, net cash provided by financing activities was $415.6 million, consisting primarily of net proceeds from the IPO of $263.7 million, net proceeds from the issuance of 2020 Notes of $151.3 million and proceeds from the exercise of stock options of $0.6 million.
During the year ended December 31, 2019, net cash provided by financing activities was $105.0 million, consisting of net proceeds of $104.9 million from our sales of shares of our Series A convertible preferred stock and proceeds from the exercise of stock options of $0.1 million.
Contractual Obligations and Commitments
In February 2021, we entered into a new lease agreement for our office space in San Mateo, California, in order to move from our former suites, totaling 8,075 square-feet, to a single, larger suite totaling 17,340 square-feet, and relocated in the third quarter of 2021. We accounted for this change in lease term of the original suites as a modification of the originally amended lease. Refer to Note 14 for further discussion on the accounting implications of the lease modification.
The initial annual base rent for the new suite is $1.2 million, and such amount will increase by 3% annually on each anniversary of the new premises commencement date. In connection with the larger space leased, we have also made an additional one-time cash security deposit in the amount of $59,000. The new lease commenced in April 2021 while tenant improvements were being made and the new lease agreement extends the termination date from April 30, 2025 to August 31, 2026.
In 2020, we entered into additional lease agreements to expand our office and lab spaces. On February 28, 2020, we entered into an 11-year lease agreement to move our research and development operations to a 40,514 square-foot facility at 301 Binney Street, Cambridge, Massachusetts (new Cambridge facility). The initial annual base rent is approximately $4.1 million and such amount will increase by 3% annually on each anniversary of the rent commencement date, which was October 2020.
Pursuant to the Gilead Asset Purchase Agreement, we are obligated to make milestone payments upon the achievement of specified regulatory and clinical milestones as well as royalty payments. The payment obligations under this agreement are contingent upon future events, such as our achievement of specified milestones or generating product sales. We are currently unable to estimate the timing or likelihood of achieving these milestones or generating future product sales. See the subsection titled “—Strategic Agreements—Gilead Asset Purchase Agreement” above.
Pursuant to the Tempus Agreement, we are obligated to make milestone payments upon the achievement of specified regulatory milestones as well as annual minimum commitments in quarterly installments. Some payment obligations under this agreement are contingent upon future events, such as our achievement of specified milestones. We are currently unable to estimate the timing or likelihood of achieving these milestones. See the subsection titled “—Strategic Agreements—Tempus R&D Services Agreement” above.
We enter into contracts in the ordinary course of business with CROs for clinical trials, preclinical and clinical research studies and testing, manufacturing and other services and products for operating purposes. These contracts do not contain any minimum purchase commitments and are generally terminable by us upon prior notice. Payments due upon termination generally consist only of payments for services provided and expenses incurred up to the date of termination.

Critical Accounting Policies and Estimates
Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of our financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies and estimates are described in more detail in the notes to our financial statements included elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.
The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including expenses, clinical trials and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international markets. We have made estimates of the impact of COVID-19 within our financial statements and there may be changes to those estimates in future periods. Actual results could differ from our estimates.
Accrued Research and Development Expenses
As part of the process of preparing our financial statements, we are required to estimate our accrued research and development and manufacturing expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed on a pre-determined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:
•CROs in connection with performing research activities on our behalf and conducting preclinical studies and clinical trials on our behalf;
•investigative sites or other service providers in connection with clinical trials;
•vendors in connection with preclinical and clinical development activities; and
•vendors related to product manufacturing and development and distribution of preclinical and clinical supplies.
We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple CROs that conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract, which may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the completion of scientific milestones. In accruing fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may
120
result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.
We believe that the assumptions and estimates associated with accrued research and development expenditures and stock-based compensation have the most significant impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.
Stock-Based Compensation
We measure stock options and other stock-based awards granted to employees, directors, and non-employees based on their fair value on the date of grant and recognize stock-based compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. We recognize the impact of forfeitures on stock-based compensation expense as forfeitures occur. We apply the straight-line method of expense recognition to all awards with only service-based vesting conditions.
We estimate the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model. This model requires the use of highly subjective assumptions to determine the fair value of stock-based awards, including:
•Fair Value of Common Stock—For grants before the completion of our IPO in October 2020 when we were a privately held company with no public market for our common stock, the fair value of our common stock underlying share-based awards was estimated on each grant date by our Board of Directors. In order to determine the fair value of our common stock underlying option grants, our Board of Directors considered, among other things, valuations of our common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accounts Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. For all grants subsequent to our IPO in October 2020, the fair value of common stock was determined by taking the closing price per share of common stock as reported on the Nasdaq Stock Market.
•Expected Term—The expected term represents the period that the stock-based awards are expected to be outstanding. We use the simplified method to determine the expected term, which is based on the average of the time-to-vesting and the contractual life of the options.
•Expected Volatility—The expected volatility for the years ended December 31, 2021, 2020 and 2019 is estimated based on the average historical volatilities of common stock of comparable publicly traded entities over a period equal to the expected term of the stock option grants. The comparable companies are chosen based on their size, stage in the product development cycle or area of specialty. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of our own stock price becomes available.
•Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the expected term of the awards.
•Expected Dividend—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.
See Note 10 to our financial statements included elsewhere in this Annual Report to Form 10-K for information concerning certain of the specific assumptions we used in applying the Black-Scholes option-pricing model to determine the estimated fair value of our stock options granted in the years ended December 31, 2021, 2020, and 2019.
Stock-based compensation expense was $26.2 million, $3.8 million and $0.1 million during the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021, we had $49.9 million, $17.9 million, and $0.3 million of total unrecognized stock-based compensation costs for stock options, restricted stock units, and restricted stock awards, respectively, which we expect to recognize over a weighted-average period of 2.93, 2.01, and 2.58 years, respectively.

Recently Issued and Adopted Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is provided in Note 2 to our financial statements included elsewhere in Item 8 of Part II of this Annual Report on Form 10-K.
122
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
We are exposed to market risk related to changes in interest rates of our investment portfolio of cash equivalents, short-term investments, and long-term investments. As of December 31, 2021, our cash equivalents and short-term investments consisted of money market funds, corporate bonds, and U.S. Treasury securities. As of December 31, 2021, we did not have any long-term investments. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. The fair value of our marketable securities is subject to change as a result of potential changes in market interest rates, including changes resulting from the impact of the COVID-19 pandemic. The potential change in fair value for interest rate sensitive instruments has been assessed on a hypothetical 100 basis point adverse movement across all maturities. If a 100 basis point increase or decrease in interest rates were to have occurred on December 31, 2021, this change would not have had a material impact on our financial statements included in Item 8 of Part II of this Annual Report on Form 10-K.
Foreign Currency Exchange Risk
All of our employees and our operations are currently located in the United States and our expenses are generally denominated in U.S. dollars. However, we have entered into a limited number of contracts with vendors for research and development services that permit us to satisfy our payment obligations in U.S. dollars (at prevailing exchange rates) but have underlying payment obligations denominated in foreign currencies, primarily including the Euro. We are subject to foreign currency transaction gains or losses on our contracts denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material to our financial statements, and we have not had a formal hedging program with respect to foreign currency. We believe a hypothetical 100 basis point increase or decrease in exchange rates at December 31, 2021 would not have had a material effect on our financial statements included in Item 8 of Part II of this Annual Report on Form 10-K.
Effects of Inflation
Inflation generally affects us by increasing our cost of labor and clinical trial costs. We believe that inflation has not had a material effect on our financial statements included in Item 8 of Part II of this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Kronos Bio, Inc.
Opinion on the Financial Statements
We have audited the accompanying balance sheets of Kronos Bio, Inc., (the Company) as of December 31, 2021 and 2020, the related statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 24, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

Notes to Financial Statements
1.NATURE OF OPERATIONS AND BASIS OF PRESENTATION
Kronos Bio, Inc. (Kronos or the Company), a Delaware corporation, was incorporated on June 2, 2017. The Company is an integrated discovery through late-stage clinical development biopharmaceutical company, with a focus on developing therapeutics that target the dysregulated transcription that causes cancer and other serious diseases.
The Company operates in one business segment, the development of biopharmaceutical products.
Basis of Presentation
The accompanying financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and accounting principles generally accepted in the United States of America (GAAP).
Initial Public Offering
In October 2020, the Company completed an initial public offering (IPO) of its common stock. In connection with its IPO, the Company issued and sold 15,131,579 shares of its common stock, which included 1,973,684 shares of its common stock issued and sold pursuant to the full exercise of the underwriters’ option to purchase additional shares, at a price to the public of $19.00 per share. As a result of the IPO, the Company received $263.7 million in net proceeds, after deducting underwriting discounts and commissions of $20.1 million and offering expenses of $3.7 million payable by the Company. At the closing of the IPO, all then outstanding shares of convertible preferred stock were automatically converted into 22,687,625 shares of common stock, and the then outstanding 2020 Notes (see Note 15) were automatically converted into 9,610,713 shares of common stock. At the closing of the IPO, the then outstanding Gilead Note (see Note 13) was also converted into 188,567 shares of common stock. Following the IPO, there were no shares of convertible preferred stock outstanding.
Forward Stock Split
On October 2, 2020, the Company filed an amendment to the Company’s amended and restated certificate of incorporation to effect a forward split of shares of the Company’s common stock on a 1.055 -for-1 basis (the Forward Stock Split). In connection with the Forward Stock Split, the conversion ratio for the Company’s outstanding convertible preferred stock was proportionally adjusted such that the common stock issuable upon conversion of such preferred stock was increased in proportion to the Forward Stock Split. The par value of the common stock was not adjusted as the result of the Forward Stock Split. All references to common stock, options to purchase common stock, early exercised options, share data, per share data, convertible preferred stock (to the extent presented on an as-converted to common stock basis) and related information contained in these financial statements have been retrospectively adjusted to reflect the effect of the Forward Stock Split for all periods presented.
Need for Additional Capital
The Company has incurred operating losses and expects to continue to generate operating losses for the foreseeable future. The Company’s ultimate success depends on the outcome of its research and development activities. The Company had cash, cash equivalents and investments of $339.5 million as of December 31, 2021. Since inception through December 31, 2021, the Company has incurred a cumulative net operating loss of $263.0 million. Management expects to incur additional losses in the future to fund its operations and conduct product research and development and recognizes the need to raise additional capital to fully implement its business plan.
130
KRONOS BIO, INC.
Notes to Financial Statements
The Company intends to raise additional capital through the issuance of equity securities, debt financings or other sources in order to further implement its business plan. However, if such financing is not available when needed and at adequate levels, the Company will need to reevaluate its operating plan and may be required to delay the development of its product candidates. The Company expects that its cash and cash equivalents and investments will be sufficient to fund its operations for a period of at least one year from the date the accompanying financial statements are filed with the Securities and Exchange Commission (SEC).
The Company cannot at this time predict the specific extent, duration, or full impact that the COVID-19 pandemic will have on its financial condition and operations, including ongoing and planned clinical trials. The impact of the COVID-19 pandemic on the financial performance of the Company will depend on future developments, including the duration and spread of the pandemic and related governmental advisories and restrictions. These developments and the impact of the COVID-19 pandemic on the financial markets and the overall economy are highly uncertain. If the financial markets and/or the overall economy are impacted for an extended period, the Company’s results may be adversely affected.
The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including expenses, clinical trials and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international markets.
The future viability of the Company is dependent on its ability to generate cash from operating activities or to raise additional capital to finance its operations. The Company’s failure to raise capital as and when needed could have a material adverse effect on its financial condition and ability to pursue business strategies. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaboration arrangements or obtain government grants. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce, or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects. In the event that the Company requires additional funding, there can be no assurance that it will be successful in obtaining sufficient funding on terms acceptable to the Company to fund its continuing operations, if at all.
2.SIGNIFICANT ACCOUNTING POLICIES, ESTIMATES AND JUDGMENTS
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, the accrual of research and development expenses, the fair value of investments, income tax uncertainties, the valuation of equity instruments and the incremental borrowing rate for determining the operating lease assets and liabilities. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from the Company’s estimates.
Research and Development Expenses
Research and development (R&D) expenses consist primarily of personnel costs, including salaries, benefits and stock-based compensation, discovery and development research performed by contract research organizations (CROs), investigator grants, materials and supplies, licenses and fees and overhead allocations consisting of various support and facility-related costs. The Company expenses R&D costs as the services are performed or the goods are received. Research and development expenses for the year ended December 31, 2021 included a $29.0 million milestone payment to Gilead which became payable upon initiation of the Company’s registrational Phase 3 clinical trial of entospletinib in combination with induction chemotherapy in acute myeloid leukemia patients with NPM1 mutations. Research and development expenses for the year ended December 31, 2020 included $6.6 million related to acquired intangible assets as research and development
131
KRONOS BIO, INC.
Notes to Financial Statements
costs pursuant to the Asset Purchase Agreement with Gilead (see Note 13) as, at the time of acquisition of the asset, the technology was under development; was not approved by the U.S. Food and Drug Administration or other regulatory agencies for marketing; had not reached technical feasibility; or otherwise had no foreseeable alternative future use. There were no acquired intangible assets expensed for the years ended December 31, 2021 and 2019.
CRO costs are a significant component of R&D expenses. The Company monitors levels of performance under each significant contract through communications with its CROs. The Company accrues costs for discovery research and development performed by CROs over the service periods specified in the contracts and adjusts its estimates, if required, based upon its ongoing review of the level of effort and costs actually incurred by the CROs. All of the Company’s material CRO contracts are terminable by the Company upon written notice and it is generally only liable for actual services completed by the CRO and certain non-cancellable expenses incurred at any point of termination.
Cash and Cash Equivalents
The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.
Restricted Cash
Concentration of Credit Risk and Other Risks and Uncertainties
Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents and investments. The primary objectives for the Company’s investment portfolio are the preservation of capital and the maintenance of liquidity. The Company does not enter into any investment transaction for trading or speculative purposes.
The Company’s investment policy limits investments to certain types of instruments such as certificates of deposit, money market instruments, obligations issued by the U.S. government and U.S. government agencies as well as corporate debt securities, and places restrictions on maturities and concentration by type and issuer. The Company maintains cash balances in excess of amounts insured by the FDIC and concentrated within a limited number of financial institutions. The accounts are monitored by management and management believes that the financial institutions are financially sound, and, accordingly, minimal credit risk exists with respect to these financial institutions. As of December 31, 2021 and 2020, the Company has not experienced any credit losses in such accounts or investments.
The Company is subject to a number of risks common for biopharmaceutical companies, including, but not limited to, dependency on the clinical and commercial success of its product candidates, ability to obtain regulatory approval of its product candidates, the need for substantial additional financing to achieve its goals, uncertainty of broad adoption of its approved products, if any, by physicians and patients, significant competition, and untested manufacturing capabilities.
Investments
Investments are available-for-sale and are carried at estimated fair value. The Company’s valuations of available-for-sale securities are generally derived from independent pricing services based upon quoted prices in active markets for similar securities, with prices adjusted for yield and number of days to maturity, or based on industry models using data inputs, such as interest rates and prices that can be directly observed or corroborated in active markets. Management determines the appropriate classification of its investments in debt securities at the time of purchase. Investments with original maturities beyond three months at the date of purchase and which mature at, or less than 12 months from, the balance sheet date are classified as short-term investments.
132

Notes to Financial Statements
Fair Value Measurement
Assets and liabilities recorded at fair value on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:
Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3— Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The fair value estimates are made at a discrete point in time based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
As of December 31, 2021 and 2020, the Company recorded financial assets requiring fair value measurement. The financial assets include cash equivalents and investments. The financial liabilities recorded during the year ended December 31, 2020, consisting of the convertible promissory note (Gilead Note) from the Gilead Asset Purchase Agreement (see Note 13) and the convertible promissory notes (2020 Notes) sold in August 2020 (see Note 15), were settled upon the closing of the IPO. As a result, there were no financial liabilities requiring fair value measurement as of December 31, 2021 and 2020.
Fair Value Option
Under U.S. GAAP, the Company has the irrevocable option to report most financial assets and financial liabilities at fair value on an instrument by instrument basis, with changes in fair value reported in the statements of operations and comprehensive loss. The option was elected for the treatment of the Company’s convertible promissory note from the Gilead Asset Purchase Agreement entered into in July 2020 (see Note 13) and the convertible promissory notes (2020 Notes) sold in August 2020 (see Note 15) in order to more accurately reflect the economic value of the notes at the time of issuance and again upon settlement.

Notes to Financial Statements
Property and Equipment, Net
Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized over the lesser of their useful lives or the remaining life of the lease. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the balance sheet and the resulting gain or loss is reflected in the statements of operations and comprehensive loss in the period realized. Repairs and maintenance costs are expensed as incurred.
Estimated useful lives in years are generally as follows:
| Description | Estimated Useful Life | |||||||
| Lab equipment | ||||||||
| Leasehold improvements | Shorter of useful life or lease term | |||||||
| Furniture and fixtures | ||||||||
| Computer equipment | ||||||||
Leases
The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, current portion of operating lease liabilities, and noncurrent operating lease liabilities on the Company’s balance sheet. Finance leases are included in property and equipment, current portion of other liabilities, and other noncurrent liabilities on the balance sheet.
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments and initial direct costs incurred, net of lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company elected to exclude from its balance sheets recognition of leases having a term of 12 months or less (short-term leases) and elected to not separate lease components and non-lease components for its long-term real-estate leases.
Impairment of Long-Lived Assets
Long-lived assets, including property and equipment, are reviewed for impairment whenever facts or circumstances either internally or externally may suggest that the carrying value of an asset or asset group may not be recoverable. Should there be an indication of impairment, the Company tests for recoverability by comparing the estimated undiscounted future cash flows expected to result from the use of the asset or asset group and its eventual disposition to the carrying amount of the asset or asset group. Any excess of the carrying value of the asset or asset group over its estimated fair value is recognized as an impairment loss.
134
KRONOS BIO, INC.
Notes to Financial Statements
Stock-Based Compensation
The Company has an equity incentive plan under which various types of equity-based awards are granted, including stock options, restricted stock awards (RSAs), and restricted stock units (RSUs). Prior to the year ended December 31, 2020, only stock options had been issued under the plan. The Company measures stock-based awards granted to employees and nonemployees based on the fair value on the date of the grant and recognizes stock-based compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. The Company calculates the fair value measurement of stock options using the Black-Scholes option-pricing model. Forfeitures are accounted for as they occur. The fair value of the RSA and RSUs is equal to the fair value of the Company’s common stock on the grant date of the award.
Income Taxes
The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of the assets and liabilities using the enacted tax rates in effect in the years in which the differences are expected to reverse. A valuation allowance against deferred tax assets is recorded if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.
Comprehensive Loss
Comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with stockholders. For the years ended December 31, 2021, 2020 and 2019, other comprehensive loss consisted of unrealized gains and losses from available-for-sale securities.
Net Loss Per Share
Basic net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the sum of the weighted-average number of shares of common stock outstanding during the period and the effect of dilutive securities.
In periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share, since dilutive shares of common stock are not assumed to have been issued if their effect on net loss per share is anti-dilutive.

Notes to Financial Statements
3.FAIR VALUE MEASUREMENTS
The Company follows authoritative accounting guidance, which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.
The Company measures and reports its cash equivalents, investments, and convertible notes at fair value.
Money market funds are measured at fair value on a recurring basis using quoted prices and are classified as Level 1. Investments measured at fair value based on inputs other than quoted prices that are derived from observable market data are classified as Level 2.
Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type as of December 31, 2021 and 2020 were as follows:

The carrying amounts of accounts payable and accrued expenses approximate their fair values due to their short-term maturities. The Company’s Level 2 securities are valued using third-party pricing sources. The pricing services utilize industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly.

10.STOCK-BASED COMPENSATION
2020 Equity Incentive Plan
In October 2020, the Company adopted its 2020 Equity Incentive Plan (the 2020 Plan) which replaced the 2017 Equity Incentive Plan (Prior Plan) upon completion of the IPO. The 2020 Plan provides for the grant of incentive stock options or nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other forms of awards to employees, directors, and consultants of the Company. Under the 2020 Plan, the maximum number of shares of common stock that may be issued increased to 11,938,152 shares. The number of shares of common stock reserved for issuance under the 2020 Plan will automatically increase each year for a period of ten years , beginning in 2021 and continuing through 2030, in an amount equal to (1) 5.0 % of the total numbers of shares of the Company’s common stock outstanding on December 31st of the immediately preceding year, or (2) a lesser number of shares determined by the Board of Directors no later than December 31st of the immediately preceding year. As a result of the automatic annual increases, the maximum number of shares of common stock that may be issued under the 2020 Plan as of December 31, 2021 was 14,739,827 shares.
Under the 2020 Plan, the exercise prices, vesting, and other restrictions are determined at the discretion of the Board of Directors, or a designated committee thereof, except that the exercise price per share of stock options may not be less than 100 % of the fair market value of the common stock on the date of grant and the term of stock option may not be greater than 10 years. The Company recognizes the impact of forfeitures on stock-based compensation expense as forfeitures occur. The Company applies the straight-line method of expense recognition to all awards with only service-based vesting conditions. Vesting periods are determined at the discretion of the Board of Directors. Stock options typically vest over four years . The maximum contractual term is 10 years.
As of December 31, 2021 and 2020, there were 4,647,580 and 3,696,370 shares, respectively, reserved by the Company under the 2020 Plan for the future issuance of equity awards.
Stock Option Valuation
The Company estimates the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model. This model requires the use of highly subjective assumptions to determine the fair value of stock-based awards, including:
•Fair Value of Common Stock—For grants before the completion of the IPO in October 2020 when the Company was a privately held company with no public market for its common stock, the fair value of its common stock underlying share-based awards was estimated on each grant date by its Board of Directors. In order to determine the fair value of our common stock underlying option grants, the Company’s Board of Directors considered, among other things, valuations of its common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accounts Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. For all grants subsequent to our IPO in October 2020, the fair value of common stock was determined by taking the closing price per share of common stock as reported on the Nasdaq Stock Market.
•Expected Term—The expected term represents the period that the stock-based awards are expected to be outstanding. The Company uses the simplified method to determine the expected term, which is based on the average of the time-to-vesting and the contractual life of the options.
•Expected Volatility—The expected volatility for the years ended December 31, 2021, 2020 and 2019 is estimated based on the average historical volatilities of common stock of comparable publicly traded entities over a period equal to the expected term of the stock option grants. The comparable companies are chosen based on their size, stage in the product development cycle or area of specialty. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.
141
KRONOS BIO, INC.
Notes to Financial Statements
•Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the expected term of the awards.
•Expected Dividend—The Company has never paid dividends on its common stock and has no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero.
The Black-Scholes option-pricing model assumptions that the Company used to determine the grant-date fair value of stock options for the years ended December 31, 2021, 2020, and 2019 were as follows, presented on a weighted-average basis:
| Year Ended December 31, | |||||||||||||||||

| Expected term (in years) | |||||||||||||||||
| Expected volatility | % | ||||||||||||||||
| Risk-free interest rate | % | ||||||||||||||||
| Expected dividend | % | ||||||||||||||||
The weighted-average grant-date fair value per share of stock options granted, using the assumptions listed above, was $18.52 , $7.25 , and $1.42 during the years ended December 31, 2021, 2020, and 2019, respectively.

(1) Included in forfeited are 12,748 options that were early exercised, but not yet vested at the time of termination of the grantee, and repurchased by the Company. The weighted-average exercise price of the repurchased options was $0.61 per share.
The aggregate intrinsic values of options outstanding, exercisable, vested and expected to vest were calculated as the difference between the exercise price of the options and the closing price of the Company’s common stock on the Nasdaq Global Select Market on December 31, 2021. The intrinsic value of options exercised for the years ended December 31, 2021, 2020, and 2019 was $23.8 million, $6.1 million and $0.7 million, respectively, determined as of the applicable date of exercise. There was no future tax benefit related to options exercised, as the Company had accumulated net operating losses as of December 31, 2021 and December 31, 2020.

2020 Employee Stock Purchase Plan
In October 2020, the Company adopted its 2020 Employee Stock Purchase Plan (ESPP), which initially reserved 688,000 shares of the Company’s common stock for employee purchase under terms and provisions established by the Board of Directors. The number of shares of our common stock reserved for issuance under the ESPP automatically increases in 2021 and continuing through 2030, by the lesser of (i) 1.0 % of the total number of shares of common stock outstanding on December 31st of the immediately preceding year, and (ii) 1,376,000 shares, except before the date of any increase, the Board of Directors may determine that such increase will be less than the amount set forth in clauses (i) and (ii). Effective January 1, 2021, the number of shares authorized under the ESPP for employee purchases increased by 560,335 shares. The ESPP is intended to qualify as an ‘employee stock purchase plan’ under Section 423 of the Internal Revenue Code. Under the current offering adopted pursuant the ESPP, each offering period shall not exceed 27 months, with shorter duration purchase periods within each offering. Employees are eligible to participate if they are employed by the Company for at least 20 hours per week and more than five months of the year. The Company issued and sold 95,723 shares of common stock under the ESPP during the year ended December 31, 2021 and no 1,152,612 shares reserved for future issuance under the ESPP as of December 31, 2021.
Under the ESPP, employees may purchase common stock through payroll deductions at a price equal to 85% of the lower of the fair market value of common stock on the first trading day of each offering period or on the purchase date. The initial offering period commenced on October 8, 2020, the date of the underwriting agreement related to the Company’s IPO. A new offering (Subsequent Offering) automatically began in 2021, and a new offering will begin every six months thereafter over the term of the ESPP. Each Subsequent Offering will be approximately 24 months long and will consist of four purchase periods (with the purchase dates occurring on June 30 and December 31 each year during the term of the Subsequent Offering). Contributions under the ESPP are limited to a maximum of 15% of an employee’s eligible compensation.
The fair values of the rights granted under the ESPP were calculated using the following assumptions:

For the year ended December 31, 2020, the Company granted 274,341 restricted stock awards (RSAs) to a certain executive officer pursuant to the 2020 Plan. The RSAs are subject to lapsing repurchase rights and in order to vest, are subject to the holder’s service to the Company.
The Company recorded stock-based compensation expense for the RSAs of $0.1 million, $0.6 million, and zero in general and administrative expenses and $5,000 , $5,000 , and $5,000 in research and development expenses in the statements of operations and comprehensive loss for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, there was $0.3 million of unrecognized stock-based compensation related to RSAs, which is expected to be recognized over a weighted average period of 2.58 years.
The total grant date fair value for RSAs vested during the years ended December 31, 2021, 2020, and 2019 was $0.2 million, $0.6 million, and $5,000 , respectively.
For the years ended December 31, 2021 and 2020, the Company issued 347,267 and 565,417 , restricted stock units (RSUs), respectively, to executive officers and non-executive employees pursuant to the 2020 Plan. These RSUs have a three year vest period and in order to vest, the holder is required to provide service to the Company.
The Company recognized $8.5 million of stock-based compensation expense related to the RSUs for the year ended December 31, 2021, of which $4.1 million and $4.4 million are recorded in research and development and general and administrative expenses, respectively, in the current year statement of operations and comprehensive loss.

Early Exercised Options
The terms of certain stock options granted under the Prior Plan allow the holder to exercise options prior to vesting. The shares related to early exercised stock options are subject to the Company’s lapsing repurchase right upon termination of employment or service on the Board of Directors at the lesser of the original purchase price or fair market value at the time of repurchase. In order to vest, the holders are required to provide continued service to the Company. The early exercise by an employee or consultant of a stock option is not considered to be a substantive exercise for accounting purposes, and therefore the payment received by the employer for the exercise price is recognized as a liability. For accounting purposes, unvested early exercised shares are not considered issued and outstanding and therefore are not reflected as issued and outstanding in the accompanying statements of convertible preferred stock and stockholders' equity (deficit) until the awards vest.
The deposits received are initially recorded in current portion of other liabilities and other noncurrent liabilities for the noncurrent portion. The liabilities are reclassified to common stock and paid-in capital as the repurchase right lapses. During the years ended December 31, 2021 and 2020, zero and 1,551,361 options were early exercised, respectively. At December 31, 2021 and 2020, there was $1.4 million and $2.2 million recorded in current portion of other liabilities, and $1.1 million and $2.5 million recorded in other noncurrent liabilities, respectively, related to shares held by employees and nonemployees that were subject to repurchase.

The Company assesses its past earnings history, income tax planning and projections of future net income when determining whether it is more likely than not future tax benefits will be realized. Based on the Company’s history of losses, the Company has maintained a full valuation allowance of approximately $58.7 million and $20.8 million for the years ended December 31, 2021 and 2020, respectively. The change in valuation allowance of $37.9 million is due to increases in net operating losses and other deferred tax assets due to current year activity.

R&D Services Agreement
In October 2021, the Company entered into an agreement for research and development services (Tempus Agreement) with Tempus Labs, Inc. (Tempus), pursuant to which Tempus agreed to provide the Company with research and development services for a period of three years . The three primary services are analytical services, data licensing, and organoid services. The Company intends to utilize the services contemplated under the Tempus Agreement to advance the development of KB-0742 and lanraplenib.
In consideration for the access to the services throughout the term of the Tempus Agreement, the Company has agreed to pay an annual minimum commitment of $1.5 million in year one, $2.0 million in year two, and $2.5 million in year three. Payments are made in quarterly installments. As of December 31, 2021, the Company has not made any payments under the Tempus Agreement.
In addition, the Company is required to make milestone payments upon successful achievement of certain regulatory milestones for KB-0742, lanraplenib, and other discovery pipeline compounds up to a combined maximum of $22.4 million. For each milestone payment that becomes due, the Company has the right to pay up to 50 % of such milestone payment amount in shares of its common stock as long as certain regulatory requirements are met.
Asset Purchase Agreement
In July 2020, the Company entered into an asset purchase agreement (Gilead Asset Purchase Agreement) with Gilead Sciences, Inc. (Gilead), pursuant to which the Company acquired certain assets from Gilead related to entospletinib and lanraplenib, and patents and other intellectual property covering or related to the development, manufacture and commercialization of entospletinib and lanraplenib.
In consideration for such assets, on the date of the Gilead Asset Purchase Agreement, the Company made a $3.0 million upfront cash payment and issued a $3.0 million principal amount convertible promissory note to Gilead (Gilead Note). The Company also made a $0.7 million payment to reimburse Gilead for certain liabilities assumed by the Company pursuant to the Gilead Asset Purchase Agreement. In addition, the Company is required to make milestone payments upon successful achievement of certain regulatory and sales milestones for entospletinib, lanraplenib and other selective spleen tyrosine kinase inhibitor compounds covered by the patent rights acquired pursuant to the Gilead Asset Purchase Agreement and developed by the Company as a back-up to entospletinib or lanraplenib (Other Compounds). Upon initiation of the Company’s registrational Phase 3 clinical trial of entospletinib in combination with induction chemotherapy in acute myeloid leukemia patients with NPM1 mutations in December 2021, the Company paid a milestone payment to Gilead of $29.0 million. Upon successful completion of certain other regulatory milestones in the United States, European Union and United Kingdom for entospletinib, lanraplenib and any Other Compounds, across up to two distinct indications, the Company will be required to pay to Gilead an aggregate total of $51.3 million. Upon achieving certain thresholds for the aggregate annual net sales of entospletinib, lanraplenib and any Other Compounds combined, the Company would owe to Gilead potential milestone payments totaling $115.0 million.
Gilead is also eligible to receive (i) tiered marginal royalties ranging from the very low-teens to high-teens on annual worldwide net sales of entospletinib, (ii) tiered marginal royalties ranging from high-single digits to the mid-teens on annual worldwide net sales of lanraplenib and (iii) tiered marginal royalties ranging from low single digits to mid-single digits on annual worldwide net sales of any Other Compounds. The royalties in the foregoing clauses are subject to reduction, on a country-by-country basis, for products not covered by certain claims within the assigned patents, for generic entry and, in the case of entospletinib and lanraplenib, for any royalties paid for future licenses of third party intellectual property required to develop or commercialize entospletinib or lanraplenib. The Company’s royalty obligation with respect to a given product in a given country begins upon the first commercial sale of such product in such country and ends on the latest of (i) expiration of the last claim of a defined set of the assigned patent rights covering such product in such country; (ii) loss of exclusive data or marketing rights to such product in such country; or (iii) 10 years from the first commercial sale of such product in such country.

Notes to Financial Statements
Under the Gilead Asset Purchase Agreement, the Company is required to use commercially reasonable efforts to develop, obtain regulatory approval for and commercialize either entospletinib or lanraplenib.
The Gilead Note accrued interest at a rate of 6 % per year, compounded annually, and had a maturity date of July 14, 2022. The Gilead Note, including unpaid accrued interest, was settled in exchange for 188,567 shares of common stock in connection with the closing of the Company’s IPO (See Note 1) at a settlement price of $16.15 per share, which is equal to 85 % of the price per share to the public in the IPO.
On issuance, the Company had elected to account for the Gilead Note at fair value with any changes in fair value being recognized through the statements of operations and comprehensive loss until the Gilead Note settled. The fair value of the Gilead Note was determined to be $3.6 million on issuance.
The Company determined the fair value of the Gilead Note at inception by determining the present value of the Gilead Note if they were to settle either upon closing of an IPO, a deemed liquidation, or a qualified or non-qualified equity fundraise. Key valuation assumptions are as follows:
| At inception | ||||||||||||||||||||||||||||||||
| Fundraise scenario | IPO cash payout scenario | IPO conversion scenario | Liquidation cash payout scenario | Liquidation conversion scenario | ||||||||||||||||||||||||||||
| Expected term (years) | ||||||||||||||||||||||||||||||||
| Discount rate | % | % | % | |||||||||||||||||||||||||||||
| Weighting | % | % | % | % | % | |||||||||||||||||||||||||||
The fair value upon settlement was determined by calculating the fair value of the 188,567 shares converted at the price per share to the public upon the closing of the IPO of $19.00 , resulting in a fair value upon settlement of $3.6 million.
In the normal course of business, the Company enters into contracts with CROs for preclinical studies and other vendors for other services and products for operating purposes. These agreements generally provide for termination or cancellation, other than for costs already incurred.
Contingencies
In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown, because it involves claims that may be made against the Company in the future, but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated.
Indemnification
In accordance with the Company’s amended and restated certificate of incorporation and amended and restated bylaws, the Company has indemnification obligations to its officers and directors for certain events or occurrences, subject to certain limits, while they are serving in such capacity. There have been no claims to date, and the Company has a directors and officers liability insurance policy that may enable it to recover a portion of any amounts paid for future claims.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURES
None.
ITEM 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based, in part, upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, has evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
An evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal year and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. During the year ended December 31, 2021, we implemented a newly licensed enterprise resource planning (ERP) information technology system to manage certain aspects of our operations, including our financial reporting. Other than this change mentioned, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We will continue to evaluate the effectiveness of internal controls, procedures, and technology on an on-going basis to maximize efficiency and productivity.
Management’s Annual Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rule 13a-15(f) of the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
154
Management has assessed the effectiveness of our internal control over financial reporting based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 framework). Based on our evaluation, management has concluded that our internal control over financial reporting was effective as of December 31, 2021.
The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their attestation report herein, which expresses an unqualified opinion on the effectiveness of our internal control over financial reporting as of December 31, 2021.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Kronos Bio, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Kronos Bio, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Kronos Bio, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2021 financial statements of the Company and our report dated February 24, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.
Anti-Takeover Provisions of Delaware Law and Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws
Section 203 of the Delaware General Corporation Law
We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:
•before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;
•upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
•on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.
Section 203 defines a “business combination” to include the following:
•any merger or consolidation involving the corporation and the interested stockholder;
•any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;
•subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
•any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; and
•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.
In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.
The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.
Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws
Among other things, our amended and restated certificate of incorporation and amended and restated bylaws:
•permit our board of directors to issue up to 10,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change in control;
•provide that the authorized number of directors may be changed only by resolution of our board of directors;
•provide that our board of directors will be classified into three classes of directors;
•provide that, subject to the rights of any series of preferred stock to elect directors, directors may only be removed for cause, which removal may be effected, subject to any limitation imposed by law, by the holders of at least 66 2/3% of the voting power of all of our then-outstanding shares of the capital stock entitled to vote generally at an election of directors;
•provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;
•require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent or electronic transmission;
•provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and content of a stockholder’s notice;
•provide that special meetings of our stockholders may be called only by the chairman of our board of directors, our chief executive officer or president or by our board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors, and not by our stockholders; and
•not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose.
The amendment of any of these provisions would require approval by the holders of at least 66 2/3% of the voting power of all of our then-outstanding common stock entitled to vote generally in the election of directors, voting together as a single class.
The combination of these provisions will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.
These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce our vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of delaying changes in our control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts. We believe that the benefits of these provisions, including increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could result in an improvement of their terms.
Choice of Forum
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or
former directors, officers or other employees to us or our stockholders; (iii) any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees, arising out of or pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws; (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or our bylaws; (v) any action or proceeding as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any action asserting a claim against us or any of our directors, officers or other employees governed by the internal affairs doctrine. This provision would not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claim for which the U.S. federal courts have exclusive jurisdiction.
In addition, our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.
While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Any such outside business activities that you may wish to pursue during the term of your employment with the Company shall require the prior written consent of the Company’s Chief Executive Officer. Notwithstanding the foregoing, you may continue to provide the services set forth on Exhibit A, attached hereto and made a part hereof, in the capacity set forth thereon.
(c)Your duties shall be performed primarily at 21 Erie St., Cambridge, MA 02139, or such other place as the parties may agree.
2.Start Date. Your employment shall commence on June 15, 2020, or such other date as may be agreed to by you and the Company.

(b)Performance Bonus. You shall be eligible to receive an annual performance bonus payable in cash at a target amount equal to 35% of your Base Salary, subject to the successful achievement of agreed upon individual and corporate performance goals, payable at the same time as such bonuses are generally paid to the Company’s executive

(c)Commencement Bonus. Within two weeks of your Start Date, the Company shall make a cash payment to you in the amount of Seventy-Five Thousand Dollars ($75,000) (the “Commencement Bonus”); provided, however, that if your employment with the Company is terminated within one (1) year from the Start Date (i) by you other than for Good Reason (as defined in Section 11(c)), or (ii) by the Company for Cause (as defined in the Company’s 2017 Equity Incentive Plan (the “Plan”)), then you shall be required to immediately repay the Commencement Bonus to the Company.
(d)Withholding. Except as expressly stated otherwise, the Company shall withhold all applicable federal, state and local taxes and social security and such other amounts as may be required by law from all amounts payable under this Section 3.
4.Equity Awards.
(a)Employment Options. Subject to the approval of the Board of Directors of the Company (the “Board”), or an authorized committee thereof, you shall be granted a stock option (the “Employment Option”) to purchase 325,000 shares of the Company’s common stock (the “Employment Option Shares”) pursuant to the Plan. Such grant shall be evidenced by an option agreement (the “Option Agreement”) to be entered into by and between you and the Company. In the event of a conflict between this Agreement and the Option Agreement, the terms of the Option Agreement shall control. The exercise price per Employment Option Share will be equal to the fair market value per share of the Company’s Common Stock as of the date that such Employment Option is granted.

(b)Early Exercise. All Employment Options shall be immediately exercisable with respect to one hundred percent (100%) of the Employment Option Shares in exchange for restricted shares of Common Stock of the Company (the “Restricted Shares”); provided, however, that the Restricted Shares will be subject to a repurchase right (the “Repurchase Right”) in favor of the Company that lapses in accordance with the schedule described above. Upon termination of your employment, the Company may exercise its Repurchase Right with respect to any or all Restricted Shares for which the Repurchase Right has not lapsed at a price equal to the exercise price per Employment Option Share.
(c)Accelerated Vesting.
(i)All Employment and Performance Options and Employment Option Shares shall become one hundred percent (100%) vested upon the consummation of a Change of Control (as defined in the Plan) that occurs at any time prior to the date that the Company becomes a publicly reporting company.

5.Expenses.

Under the Company’s policy, you will still be responsible for meeting the expectations and requirements of your position including timely and satisfactorily completing all work assignments while taking time off. This may include being required to respond to emails, telephone calls, mobile messages and other forms of communication. For purposes of the Company’s policy, this personal time off is in addition to company recognized holidays or sick leave. You will accrue sick leave consistent with applicable law. Sick leave may be used for yourself or a family member for the diagnosis, care or treatment of an existing health condition or preventive care, or specified purposes set forth in the Company’s policy if you are a victim of domestic violence, sexual assault, or stalking.

(iv)(A) all unvested Equity Awards and any other Company equity compensation awards you then hold shall immediately vest in full, and (B) all Equity Awards will remain exercisable for a period of 90 calendar days following the date of such termination, after which time the Equity Awards shall expire; provided, however, that no such Equity Award shall be exercisable after the expiration of its maximum term.

(iii)the vesting applicable to all Equity Awards granted to you by the Company shall cease immediately and you shall have a period of 90 days to exercise any and all vested Equity Awards, after which time all Equity Awards shall expire; provided, however, that no such Equity Award shall be exercisable after the expiration of its maximum term pursuant to the terms thereof.

Except as required by Section 13, the Payments will commence on the first payroll period following the Release Agreement becoming effective; provided, that (i) if the Payments (or any portion thereof) constitute “deferred compensation” within the meaning of Section 409A (as defined in Section 13) and (ii) the period commencing on the date of termination and ending on the Release Deadline spans two calendar years, then the Payments (or such portion thereof that constitute “deferred compensation”) will commence on the later of the Release Agreement becoming effective and the first payroll date of the Company in the second calendar year.

(e)The Company shall withhold all applicable federal, state and local taxes and social security and such other amounts as may be required by law from all amounts payable to the you under this Section 11. The provisions of this Section 11 shall survive any termination of this Agreement.

If you are, upon a separation from service, a “specified employee” within the meaning of Section 409A, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the payment of any deferred compensation shall not commence until the earlier to occur of: (i) the date that is six months and one day after your separation from service, or (ii) the date of your death. Any payments that are delayed due to the application of the preceding sentence shall be made on the date that payments commence. For purposes of Section 409A, the right to a series of installment payments under this offer letter shall be treated as a right to a series of separate payments.
14.Governing Law. The terms of this offer letter shall be governed by, and construed and interpreted in accordance with, the laws of the Commonwealth of Massachusetts without regard to such State’s principles of conflict of laws, except as provided in Section 14.
15.Arbitration. To the maximum extent permitted by law, any dispute between the parties, including but not limited to those arising out of, or relating to, this Agreement, shall be exclusively decided by binding arbitration in accordance with the terms of the Arbitration Agreement, which is attached as Exhibit D and incorporated into this Agreement. The Federal Arbitration Act shall govern the interpretation, enforcement and all proceedings pursuant to the Arbitration Agreement. To the extent that the Federal Arbitration Act is inapplicable, the terms of the Arbitration Agreement shall be construed in accordance with Massachusetts law.
16.Miscellaneous.
(a)This agreement, and your rights and obligations hereunder, may not be assigned. The Company may assign its rights, together with its obligations, hereunder in connection with any sale, transfer or other disposition of all or substantially all of its business or assets provided the assignee entity which succeeds to the Company expressly assumes the Company’s obligations hereunder and complies with the terms of this Agreement.
(b)This agreement cannot be amended orally, or by any course of conduct or dealing, but only by a written agreement signed by the parties hereto.
(c)The failure of either party to insist upon the strict performance of any of the terms, conditions and provisions of this agreement shall not be construed as a waiver or relinquishment of future compliance therewith, and such terms, conditions and provisions shall remain in full force and effect. No waiver of any term or condition of this agreement on the part of either party shall be effective for any purpose whatsoever unless such waiver is in writing and signed by such party.
(d)This agreement sets forth the entire agreement and understanding of the parties relating to the subject matter hereof, and supersedes all prior agreements, arrangements and understandings, written or oral, relating to the subject matter hereof. No representation, promise or inducement has been made by either party that is not embodied in this agreement, and neither party shall be bound by or liable for any alleged representation, promise or inducement not so set forth.
