$462.1 million in cash, cash equivalents and investments as of December 31, 2020

SAN MATEO, Calif. and CAMBRIDGE, Mass., March 23, 2021 (GLOBE NEWSWIRE) -- Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer, today reported recent business progress and fourth quarter and full year 2020 financial results.

“2020 was a transformational year for Kronos Bio, during which we made our debut as a public company through an upsized IPO and acquired a portfolio of SYK inhibitors, including the lead compound entospletinib, currently in late-stage clinical development. We also hired key talent to execute on our company’s vision and advanced the clinical development of our two lead therapeutic programs,” said Norbert Bischofberger, Ph.D., president and CEO. “Thus far in 2021, we have continued to successfully carry out our plans, including proceeding to assess MRD negative CR as the primary endpoint in our Phase 3 trial to support potential accelerated approval of entospletinib. We also dosed the first patient in our Phase 1/2 trial of KB-0742, our oral CDK9 inhibitor targeting MYC-amplified cancers, and expect to report initial safety, PK and PD data from this trial in the fourth quarter of this year. We have put together the pieces necessary for the foundation of a successful company, and I expect 2021 to be a year of important clinical execution for our company.”  

2020 and Recent Clinical and Business Highlights
