Biomea Fusion, Inc. announced that the first patient has been dosed in COVALENT-102, the company's Phase I/Ib trial of BMF-219, an oral, selective, covalent menin inhibitor in patients with KRAS-mutated unresectable, locally advanced, or metastatic NSCLC, CRC, and PDAC. KRAS is the most frequently mutated isoform amongst RAS oncogenes in human solid tumors, with high prevalence in NSCLC, CRC, and PDAC. KRAS G12C, KRAS G12D and KRAS G12V are among the most common KRAS mutations.

However, there are numerous other known activating KRAS mutations. With only two approved therapies both targeting only KRAS G12C for locally advanced or metastatic NSCLC, KRAS-driven tumors continue to represent a significant unmet medical need. As a covalent menin inhibitor, BMF-219 has manifested a differentiated profile over the commercially approved KRAS- targeted inhibitors LUMAKRAS (sotorasib) and KRAZATI (adagrasib) in multiple pre-clinical studies.

As previously reported by Biomea, KRAS-mutant NSCLC, CRC, and PDAC cell lines and ex vivo patient specimens were highly sensitive to BMF-219 in preclinical models. The higher levels of activity of BMF-219 were observed among various KRAS-mutant solid tumor cell lines, but not KRAS wild type, suggesting that BMF-219 broadly inhibited mutant KRAS in these tumor models. A targeted pan-KRAS inhibitor has the potential to treat a large number of NSCLC, CRC, and PDAC patients.

About COVALENT--102 COVALENT-102 is an open-label, multi-cohort, multicenter, Phase I/Ib dose escalation and expansion study evaluating the safety, tolerability, and optimal biologic dose of BMF-219 administered orally to adult patients with KRAS-mutated unresectable, locally advanced or metastatic NSCLC, CRC, and PDAC. Additional information about the Phase I/Ib clinical trial of BMF-219 can be found at ClinicalTrials.gov using the identifier NCT05631574. About Non-Small Cell Lung Cancer (NSCLC) NSCLC is the most common form of lung cancer, representing approximately 82% of all lung cancer cases or approximately 200,000 cases in the U.S. each year.

The five-year survival rate of NSCLC is approximately 25%. While lung cancer is the third most common form of cancer in the U.S. based on incidence, it contributes to the highest number of annual cancer deaths in the U.S. KRAS is the most frequently mutated oncogene in NSCLC, occurring in approximately 30% of patients. There remains a great unmet need for targeted therapies to address all KRAS driver mutations and avoid known mechanisms of resistance.
