BH-30643 was designed to overcome the limitations of currently approved EGFR inhibitors, which were discovered over a decade ago without the current, modern understanding of the structure and protein dynamics of mutant EGFRs. In preclinical studies, BH-30643 demonstrated potent inhibitory activity across diverse <em>EGFR<\/em> mutation categories \u2013 classical activating mutations, on-target resistance mutations such as C797S with or without T790M, atypical mutations and exon 20 insertions \u2013 while maintaining marked selectivity over wild-type EGFR. BH-30643 has received Fast Track designation and is being evaluated in SOLARA, a global Phase 1\/2, first-in-human clinical trial spanning more than 40 sites in 10 countries. Ongoing dose expansion cohorts are enrolling in both TKI-pretreated and TKI-naive settings, including a C797S resistance cohort.

Phase 1 will determine the recommended Phase 2 dose (RP2D) of BH-30643 as a monotherapy and in combination with chemotherapy.

Jean Cui, Ph.D., with her proven track record in oncology drug design and development \u2013 including three FDA-approved drugs \u2013 BlossomHill Therapeutics applies cutting-edge science with a goal to address key oncogenic drivers and improve patient outcomes in difficult-to-treat cancers. The company\u2019s lead clinical program is BH-30643, an investigational, non-covalent, macrocyclic, brain active, mutant-selective OMNI-EGFR<sup>TM<\/sup> inhibitor for the treatment of EGFR-mutant non-small cell lung cancer (NSCLC), which has received Fast Track designation for the C797S resistance population after 3rd generation EGFR TKI treatment. The company is also conducting clinical development of BH-30236, an investigational macrocyclic CDC-like kinase (CLK) inhibitor initially being studied in a clinical trial for the treatment of relapsed or refractory acute myeloid leukemia (R\/R AML) and higher-risk myelodysplastic syndrome (HR-MDS). The company\u2019s pipeline also includes BH-501284, a preclinical, non-covalent, selective, pan-KRAS Switch II inhibitor for potential future development in diverse KRAS-mutant tumors.
