BlossomHill Therapeutics is a privately held, clinical-stage biopharmaceutical company headquartered in San Diego, California, founded in 2020 by drug designer J. Jean Cui, Ph.D. and biotech operator Y. Peter Li, Ph.D., M.B.A. It develops intelligently designed small-molecule medicines for oncology and autoimmune disease, led by BH-30643, a first-in-class macrocyclic non-covalent mutant-selective OMNI-EGFR inhibitor for EGFR- and HER2-mutated non-small cell lung cancer, and BH-30236, a macrocyclic CLK inhibitor for relapsed or refractory acute myeloid leukemia and higher-risk myelodysplastic syndrome.
