Kronos Bio's oncology therapeutics segment is dedicated to the discovery and development of small molecule therapies targeting deregulated transcription in cancer. This involves extensive research into transcriptional regulatory networks and their role in driving oncogenic activity. Key programs include entospletinib (ENTO), an orally administered, selective spleen tyrosine kinase inhibitor for acute myeloid leukemia (AML) patients, and KB-0742, an orally bioavailable inhibitor of cyclin dependent kinase 9 (CDK9) for the treatment of MYC-amplified solid tumors. The company employs advanced chemical biology and systems biology approaches to identify and validate novel drug targets. Clinical trials are a critical component, with ongoing Phase 1/2 studies for KB-0742 and planned registrational Phase 3 trials for ENTO. The ultimate goal is to provide effective treatments for cancers with high unmet medical needs, improving patient outcomes and quality of life.
