About COVALENT-103
COVALENT-103 is a multicenter, open-label, non-randomized trial seeking to evaluate the safety and efficacy of BMF-500, a twice daily oral treatment, in adult patients with relapsed or refractory acute leukemia with FMS-like tyrosine kinase 3 (FLT3) wild-type and FLT3 mutations. Additional information about the Phase I clinical trial of BMF-500 can be found at ClinicalTrials.gov using the identifier, NCT05918692.

About BMF-500
BMF-500, an investigational, novel, orally bioavailable, highly potent and selective covalent small molecule inhibitor of FLT3, was discovered and developed in-house at Biomea using the company’s proprietary FUSION System and has demonstrated encouraging potential based on extensive preclinical studies. The kinase inhibitory profile of BMF-500 showed high target selectivity, suggesting the potential for reduced off-target liabilities. BMF-500 was designed to have a therapeutic profile to allow for combinations with standard of care and/or novel targeted agents like icovamenib, Biomea’s investigational covalent menin inhibitor currently in clinical development for solid and liquid tumors as well as diabetes.

Previous data presented at the 2022 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting showed BMF-500’s picomolar affinity for inhibition of activating FLT3 mutations, including FLT3-ITD and various tyrosine kinase domain (TKD) mutations. BMF-500 demonstrated multi-fold higher potency and increased cytotoxicity than the commercially available non-covalent FLT3 inhibitor gilteritinib. These data also showed complete tumor regression in mouse models of FLT3-ITD acute myeloid leukemia (AML), with no tumor regrowth even after treatment cessation.

Data presented at the 2023 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting exhibited the potential utility of combination strategies to achieve higher antileukemic cell killing with reduced concentrations of BMF-500 and icovamenib. Additionally, Biomea has shown the potential of combinatorial approaches of BMF-500 and icovamenib with MEK and BCL2 blockade in other preclinical studies. These data provide preclinical evidence for combining pathway-specific inhibitors as a promising therapeutic strategy for further investigation in acute leukemia.

About FLT3 in AML
FLT3 is a receptor tyrosine kinase (RTK) that plays a central role in the survival, proliferation, and differentiation of immature blood cells. FLT3 gene mutations are common in patients with AML and are associated with a poor prognosis. Nearly 30% of AML patients have a FLT3 mutation, representing more than 7,000 incident patients in the U.S. each year. In addition, academic literature suggests that more than 50% of AML patients with an NPM1 mutation also harbor a FLT3 mutation. While FLT3-specific and pan-tyrosine kinase inhibitors are approved by the FDA across various lines of therapy in AML, these agents have produced relatively low rates of durable responses and overall survival remains an unmet need.
