REDWOOD CITY, Calif., Dec. 07, 2023 (GLOBE NEWSWIRE) -- Biomea Fusion, Inc. (“Biomea”) (Nasdaq: BMEA), a clinical-stage biopharmaceutical company dedicated to discovering and developing novel covalent small molecules to treat and improve the lives of patients with genetically defined cancers and metabolic diseases, today announced the full abstract, titled “BMF-219: A novel therapeutic agent to reestablish functional beta cells and provide long-term glycemic control”, will be presented during the Abstract Oral Presentation Session as well as the Poster Session of the 21st World Congress Insulin Resistance, Diabetes & Cardiovascular Disease (WCIRDC) taking place in Los Angeles, California on December 7-9, 2023.

“We are honored to be selected as one of the six oral presentations by the WCIRDC Abstract Committee. We’ve seen truly promising data to date with BMF-219’s novel proposed mechanism of action which is designed to address an underlying cause of type 2 diabetes – the loss of healthy, insulin-producing beta cells. BMF-219 is the first investigational agent to show durable glycemic control during off-treatment period after four weeks of dosing. Together with the evidence in ex-vivo human islet experiments, we believe these data validate the proposed mechanism of action for BMF-219 – disruption of menin drives beta cell-specific proliferation. These data also further support the potential for BMF-219 as a disease modifying agent in type 2 diabetes. We are excited about these early findings and look forward to presenting the data during the conference,” said Juan Pablo Frias, M.D., Chief Medical Officer at Biomea.

Details for the abstract are listed below and can be viewed online on the WCIRDC conference website. Presentation slides from the Breakfast Symposium will be made available after the event on Biomea’s website. There will be a replay of the presentation once available through the WCIRDC.

Abstract #0088

BMF-219: A novel therapeutic agent to reestablish functional beta cells and provide long-term glycemic control

Presentation Time:

Poster Presentation: Thursday, December 7, 2023, 6:30pm – 7:30 pm PST

Oral Presentation: Friday, December 8, 2023, 7:30 pm – 9:00 pm PST

Abstract Text:

Background: Inhibition of menin drives an increase in beta-cell proliferation and function. BMF-219, an oral menin inhibitor, is being developed to manage diabetes. Herein we summarize BMF-219 ex-vivo human islet and T2D clinical data.

Methods: BMF-219 was evaluated in ex-vivo human islet cultures to assess beta-cell function and proliferation. In T2D, a randomized, double-blind, placebo-controlled study is ongoing. We report patients treated with BMF-219 100mg QD for 4 weeks, followed until Week 26. Endpoints include glycemic efficacy and safety.

Results: With human islet microtissues cultured for 2-3 weeks under high glucose conditions, BMF-219 increased the fraction of proliferating beta cells resulting in an increase in insulin content and glucose-stimulated insulin secretion. Gene expression changes with CCNA2 and PbK were observed, supporting beta cell proliferation, consistent with published data.

Twenty T2D patients received BMF-219 100mg QD for 4 weeks (with or without food). A reduction in HbA1C of 0.5% or greater was seen in 50% patients at Week 4, which improved to 60% at Week 12. A sustained reduction ≥0.5% was seen in 40% patients at Week 26. At this timepoint, 20% of patients experienced ≥1% HbA1c reduction, with a maximum reduction of 2.5%. BMF-219 was well tolerated (no SAEs or dose discontinuations).

Conclusions: In ex-vivo cultured islets, BMF-219 improved human beta-cell function and proliferation. In T2D, BMF-219 for 4 weeks resulted in meaningful HbA1c reductions at treatment completion (Week 4) and during the 26-week follow-up. Combined results support BMF-219 mechanism of action of beta-cell preservation, reactivation, and proliferation.


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 subjects were enrolled in single ascending dose cohorts to ensure safety at the prospective dosing levels for people with type 2 diabetes. Phase II consists of multiple ascending dose cohorts and dose durations and includes adult patients with type 2 diabetes uncontrolled by current therapies. Additional information about the Phase I/II clinical trial of BMF-219 in type 2 diabetes can be found at using the identifier NCT05731544.

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 CDC estimates about 2 in 5 of the adult population in the USA are now expected to develop diabetes during their lifetime. More than 37 million people of all ages (about 11% of the US population) have diabetes today. 96 million adults (more than 1 in 3) have pre-diabetes, blood sugars that are higher than normal but not high enough to be classified as diabetes. Diabetes is also one of the largest economic burdens on the United States health care system with $1 out of every $4 in US health care costs being spent on caring for people with diabetes. Despite the current availability of many diabetes medications, there remains a significant need in the treatment and care of patients with diabetes.
