Overview
BlossomHill Therapeutics, Inc. is a small molecule drug discovery and development company focused on unmet medical needs in oncology and autoimmune disorders. The company is founded by renowned drug design and development scientist, J. Jean Cui, Ph.D., and biotech business veteran, Y. Peter Li, Ph.D., M.B.A. BlossomHill Therapeutics, Inc. is headquartered in San Diego, California.
The company's work centers on precision cancer medicine, with small molecules intended to overcome the limitations of existing cancer therapies. It calls its chemistry-based approach the BlossomHill Way and aims to design each small molecule for selectivity, durability and safety. This approach has produced a wholly owned pipeline that includes multiple clinical-stage programs. Candidates include BH-30643, an OMNI-EGFR inhibitor for EGFR C797S-positive non-small cell lung cancer, and BH-501284, a pan-KRAS inhibitor.
The BlossomHill name comes from an ancient Chinese poem about a difficult journey overcome through perseverance, which the company relates to a patient's path through treatment.
