'We aim to cure diabetes and believe we are on the path to do so. Notably, after receiving a short, 4-week course of BMF-219, patients with type 2 diabetes are displaying durable glycemic control, and in some cases displaying continued improvement in glycemic control while off therapy. The Escalation Phase of our first in human study was quite successful, generating strong clinical data with a novel mechanism of action and importantly providing us with proof-of-concept data to support the design of the Expansion Phase which is now enrolling. The Expansion Phase will dose patients for longer treatment periods with the goal of broadening and deepening BMF-219's effect across the type 2 patient population. As presented at the ATTD conference, we believe the observations from biomarkers including HbA1c, HOMA-B, and C-peptide analysis for responders vs. non-responders, together with pharmacokinetic dose response data all point to strong evidence that BMF-219 is specifically proliferating beta cells in pancreatic islets of uncontrolled type 2 diabetes patients,' said
Data Highlights from ATTD Presentations
Efficacy Findings
Patients in COVALENT-111 are displaying improved glycemic control while off therapy, supporting improved pancreatic function following BMF-219 treatment. Patients who demonstrated the greatest HbA1c reduction at Week 26 (22 weeks off treatment), had the greatest improvement in beta cell function as measured by HOMA-B and C-peptide.
In patients failing current standard of care medications, at Week 26, following a 28 day dose cycle of BMF-219, a general dose response was observed with placebo adjusted mean percent changes of HbA1c of -0.04% (50mg QD), -0.2% (100mg QD with food), -0.8% (100mg), -0.4% (200mg QD), -0.4% (100mg BID), and -1.4% (200mg with food) (50mg data out to Week 20, latest data cut).
The efficacy seen in the 200mg with food cohort is highlighting the direct benefits of an enhanced PD effect with higher blood glucose and higher exposure, as seen in the human islet studies with BMF-219 (presented at WCIRD Dec. 2023).
A higher proportion of patients treated with 200mg QD achieved a clinically significant reduction in HbA1c compared to 100mg QD dosing. A durable glycemic response (1.0% HbA1C reduction) was seen in 20% and 36% of patients in once daily 100 mg and 200 mg cohorts, respectively.
Across 100mg QD, 200mg QD, and 100mg BID cohorts (N=40), 38% of patients had 0.5% HbA1c reduction (with a mean HbA1c reduction of 1.2%), and 23% of patients had 1.0% HbA1c reduction (with a mean HbA1c reduction of 1.5%) at Week 26.
Patients with >7 years duration of diabetes and failing dual- or triple-agent therapy (including GLP1 RA and/or SGLT2i) (n=2) also demonstrated improved glycemic control (HbA1c -0.4%, -1.1%, and -1.1% at Weeks 4, 12, and 26, respectively) with BMF-219 dosed at 200mg with food.
Increase in HOMA-B and C-peptide generally correlated with glycemic control, consistent with BMF-219's core mechanism of action: beta-cell proliferation and improved beta-cell function.
Safety and Tolerability Findings
BMF-219 was generally well tolerated with no serious adverse events and no adverse event-related study discontinuations, and no symptomatic or clinically significant hypoglycemia.
Next Steps
The Expansion Phase of COVALENT-111 is designed to further explore BMF-219's potential for long-term glycemic control by dosing BMF-219 for up to 12 weeks at various dosing levels with follow-up of 26 and 52 weeks. The Expansion Phase is currently enrolling on schedule with initial data expected in the second half of 2024.
A PK study further assessing the optimal use of BMF-219 to ensure minimal variability of exposure is currently under way.
Biomea is currently awaiting the read out and analysis of an additional 400 mg cohort, which will also help inform further inclusion into the Expansion Phase.
About COVALENT-111
COVALENT-111 is a multi-site, randomized, double-blind, placebo-controlled Phase I/II study. In the completed Phase I portion of the trial, healthy patients were enrolled in single ascending dose cohorts to evaluate safety at the prospective dosing levels for type 2 diabetic patients. Phase II consists of multiple ascending dose cohorts and includes adult patients with type 2 diabetes uncontrolled by standard of care medicines. Once the Escalation Phase of COVALENT-111 completes, the study advances into an Expansion Phase (n>200) consisting of multiple cohorts dosing type 2 diabetes patients for longer dose durations. Additional information about the Phase I/II clinical trial of BMF-219 in type 2 diabetes can be found at ClinicalTrials.gov using the identifier NCT05731544.
About COVALENT-112
COVALENT-112 is a multi-site, randomized, double-blind, placebo-controlled Phase II study in adults with stage 3 type 1 diabetes. This stage describes the period following clinical diagnosis of type 1 diabetes when symptoms are present due to significant beta cell loss. COVALENT-112 will be a multi-arm trial comparing two different doses of BMF-219 to placebo control (1:1:1) to evaluate the safety, tolerability, and efficacy of BMF-219 in persons with type 1 diabetes. Approximately 150 patients will be enrolled in the trial and will receive either BMF-219 or placebo for 12 weeks, followed by a 40 week 'off-treatment' period.
This trial will also include an open label portion for adults with type 1 diabetes up to 15 years since diagnosis. The open label portion (n=40) will examine the safety, efficacy, and durability of BMF-219 at two oral dose levels, 100 mg and 200 mg for 12-weeks of treatment followed by a 40 week off-treatment period.
About Menin's Role in Diabetes
Loss of functional beta cell mass is a core component of the natural history in both types of diabetes type 1 diabetes (mediated by autoimmune dysfunction) and type 2 diabetes (mediated by metabolic dysfunction). Beta cells are found in the pancreas and are responsible for the synthesis and secretion of insulin. Insulin is a hormone that helps the body use glucose for energy and helps control blood glucose levels. In patients with diabetes, beta cell mass and function have been observed to be diminished, leading to insufficient insulin secretion and hyperglycemia. Menin is thought to act as a brake on beta-cell turnover and growth, supporting the notion that inhibition of menin could lead to the regeneration of normal, healthy beta cells. Based on these and other scientific findings, Biomea is exploring the potential for BMF-219-mediated menin inhibition as a viable therapeutic approach to potentially halt or reverse progression of type 2 diabetes.
About Type 2 Diabetes
Diabetes is considered a chronic health condition that affects how the body turns food into energy and results in too much sugar in the bloodstream. Over time, this can cause serious health problems and damage vital organs. Most people with diabetes have a shorter life expectancy than people without this disease. The
