91-LB: COVALENT-111, a Phase 1/2 Trial of BMF-219, a Covalent Menin Inhibitor, in Patients with Type 2 Diabetes Mellitus—Preliminary Results

Type 2 Diabetes Mellitus (T2DM) is characterized by impaired glycemic control caused by insulin resistance and progressive beta cell failure. Menin, a scaffold protein, drives beta cell proliferation when inhibited. We have reported BMF-219, an oral covalent menin inhibitor, elicits durable glycemic control following a short treatment in a ZDF Rat model. COVALENT-111, a randomized, double-blind, placebo-controlled study is evaluating BMF-219 in healthy adults and adults with T2DM diagnosed ≤15 yrs (NCT05731544). Here we report initial results from the first cohort of T2DM patients treated with BMF-219. Patients with poor glycemic control (HbA1C ≥7%) on their current antidiabetic regimen were enrolled. Twelve patients were randomized 5:1 (10 BMF-219, 2 placebo) to receive 100 mg QD for 4 weeks while continuing their existing treatment. BMF-219 was well tolerated; no subjects discontinued treatment or exited the trial during the 4-week treatment and all subjects continue in follow-up to assess durability of the treatment effect. There were no dose reductions, SAEs, or severe AEs. All TRAEs were mild and observed in 3 of 12 subjects. No subjects showed symptomatic hypoglycemia. These data demonstrate preliminary proof of concept for the novel disease-modifying effect of BMF-219 in T2DM. Enrollment is ongoing at higher doses; additional follow-up data will be presented.
