First patient dosed in Phase 1/2 trial of KB-0742, an oral CDK9 inhibitor targeting MYC-amplified cancers

$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

Clinical Highlights

• In March 2021, announced that data from a pre-clinical study of KB-0742 will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2021, being held virtually April 10-15.
• In March 2021, following receipt of minutes from its End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA), announced that the company will proceed with its plan to assess measurable residual disease (MRD) negative complete response (CR) as the primary endpoint in a registrational Phase 3 trial to support potential accelerated approval of entospletinib, an investigational spleen tyrosine kinase (SYK) inhibitor being developed for the frontline treatment of patients with NPM1-mutated acute myeloid leukemia. The company plans to initiate the Phase 3 trial in mid-2021, with MRD negative CR data expected in the second half of 2023.
• In February 2021, announced that the first patient was dosed in the company’s Phase 1/2 clinical trial of KB-0742, the company’s potent oral, highly selective cyclin dependent kinase 9 (CDK9) inhibitor being developed to treat MYC-amplified solid tumors. The company announced FDA clearance of the Investigational New Drug (IND) application for KB-0742 in December 2020. Initial safety, PK and PD data from the dose-escalation stage of the Phase 1/2 study is expected in the fourth quarter of this year, with data from the study’s expansion cohorts expected in 2022.

The portfolio includes the clinical stage compounds entospletinib, which has been evaluated in Phase 1 and Phase 2 clinical trials in oncology patients, and lanraplenib, which has been evaluated in Phase 2 clinical trials in patients with autoimmune diseases.
