Kronos Bio to Present Clinical Update on Phase 1/2 Trial of KB-0742 at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting

SAN MATEO, Calif. and CAMBRIDGE, Mass., April 24, 2024 (GLOBE NEWSWIRE) -- Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer, today announced that it will present a study update of the oral CDK9 inhibitor KB-0742 in relapsed or refractory transcriptionally addicted advanced solid tumors from the ongoing Phase 1/2 trial, KB-0742-1001 (NCT04718675), at the American Society of Clinical Oncology (ASCO) Annual Meeting, being held from May 31 - June 4, 2024 in Chicago, Illinois and online.

"We are looking forward to sharing updated data from KB-0742-1001, our ongoing Phase 1/2 trial of KB-0742, including data from the 80mg three days on/four days off dosing regimen. The trial is designed to assess the safety, tolerability, and preliminary efficacy at increasing dose levels of KB-0742, an orally bioavailable and selective CDK9 inhibitor with a long half-life," said Norbert Bischofberger, Ph.D., chief executive officer and president of Kronos Bio. "Our last update at the 2023 AACR-NCI-EORTC meeting showed that KB-0742 exhibited anti-tumor activity while maintaining an acceptable safety profile at the 60mg three-days-on, four-days-off dose, which is an important step as we seek to identify the optimal dose of KB-0742."
