•  Treatment with BMF-219 led to an increase in beta cell mass in ex-vivo experiments with human donor islets

 

•  BMF-219 showed improved pancreatic beta-cell function and beta cell area, insulin sensitivity, blood lipid levels, weight decline, and glycemic control in the rat models (ZDF (Zucker Diabetic Fatty Rat) and the STZ (streptozotocin)) during the dosing period, and importantly, both glycemic and lipemic control were maintained after the dosing period ended

 

•  BMF-219 treatment resulted in a sustained increase in beta cell area and function in the ZDF diabetic rats observed at the end of treatment and two weeks following succession of therapy, compared to rats treated with vehicle or active control pioglitazone, which showed a decline in beta cell area and function

 

•  BMF-219 demonstrated, after 16 days of treatment, a recovery of beta-cell activity in STZ rats compared to rats treated with vehicle control or pioglitazone

 

•  Biomea remains on track to file an IND to explore the utility of BMF-219 in type 2 diabetes in the second half of 2022

 

REDWOOD CITY, Calif., Sept. 22, 2022 (GLOBE NEWSWIRE) — Biomea Fusion, Inc. (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, presented “Oral long-acting menin inhibitor normalizes type 2 diabetes in two rat models” at the European Association for the Study of Diabetes Annual Meeting (EASD).


  

The presentation highlighted BMF-219’s ability to improve pancreatic beta cell area and function in two preclinical rat models of diabetes. This data showed BMF-219’s robust and prolonged glycemic control, insulin sensitization, and reduction of weight and lipid levels in preclinical rat models.

 

In addition, and for the first time, Biomea Fusion presented data showing an increase in beta cell function based on HOMA-B determination in the two rat models and an increase in beta-cell area in the ZDF rat model and an increase in beta cell mass in an ex-vivo human donor beta-cell islet model. This data provides further support for the potential of BMF-219 as a long-acting, disease modifying treatment for type 2 diabetes. The preclinical presentations from EASD can be viewed on Biomea’s website at https://biomeafusion.com/publications.

 

“Today we reported direct evidence of BMF-219’s ability to increase beta cell area, another key feature of the novel mechanism. BMF-219 also displayed the ability to restore and preserve beta cell function in various type 2 diabetes models. In addition, we have continued to expand our translational work and presented a preview of the results today, showing treatment with BMF-219 led to a substantial expansion of human beta cells in an ex-vivo donor islet model,” said Thomas Butler, CEO and Chairman of Biomea Fusion.

 

Diabetes is a multi-factorial disease that typically requires daily treatment with multiple agents with various mechanisms of action to achieve glycemic control. The global burden of diabetes has been rapidly increasing with over 400 million people currently struggling with diabetes globally.

 

“These results, along with additional work, increases our understanding and our confidence in BMF-219’s ability to restore and balance beta cell mass effectively and efficiently. We are excited about the potential impact a treatment like this can have on the lives of the millions of patients worldwide with diabetes. Today, available therapies only provide symptomatic control whereas BMF-219 has the potential to be disease modifying. We look forward to updating you on our clinical development plan in diabetes in the coming months,” commented Mr. Butler

 

The data presented at EASD shows that BMF-219 was superior to pioglitazone in an oral glucose tolerance test (OGTT), an assessment of glucose metabolism and processing, in the STZ beta cell ablation model during the treatment period. In this model, BMF-219 but not active comparator, pioglitazone, restored non-fasting glucose levels to near normal baseline by treatment day eight and significantly reduced blood glucose levels vs. vehicle and pioglitazone during the OGTT in STZ rats (mean AUC reduction of 41%, p<0.05) at day 15, suggesting that BMF-219 rapidly


  

induced pancreatic beta cell regrowth and function. Furthermore, BMF-219 administration resulted in a near doubling of HOOMA-B value compared to vehicle control and pioglitazone in the STZ rat model.

 

In the other gold standard type 2 diabetes model, ZDF rats treated with BMF-219 exhibited an increase in beta cell mass and function while on BMF-219 and for two weeks after BMF-219 was removed. ZDF rats treated with vehicle and pioglitazone saw a reduction in IHC-Insulin staining, a proxy for beta cell mass of -33% and -28%, respectively, while rats treated with BMF-219 saw an increase of +2%.

 

Two weeks after BMF-219 treatment, the ZDF rats continued to see a normalization of their HOMA-B score, with approximately 350% improvement compared to vehicle treated ZDF rats, which remained highly diabetic with poor beta cell function (~75% below the normal range). In the ZDF model, BMF-219 and pioglitazone showed similar glycemic control during an OGTT while drug was present (AUC reduction of 54%, p<0.001) but only BMF-219 treated rats saw weight loss during treatment with BMF-219 and maintained glycemic control two weeks after washout (AUC reduction of 40%, p<0.05), indicating prolonged glycemic control. In addition to OGTT, blood glucose, insulin, C-peptide, Hemoglobin A1C (HbA1c), lipemic levels, and weight were also assessed.

 

We believe these data collectively demonstrate the novel, long-acting potential of BMF-219 as a single agent, disease modifying oral treatment for type 2 diabetes.

 

About Menin 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 are diminished, leading to insufficient insulin secretion and hyperglycemia. Menin is thought to act as a brake on beta-cell turnover / beta-cell 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 explored the potential for menin inhibition as a viable therapeutic approach to permanently halt or reverse progression of type 2 diabetes.

Conclusions & Next Steps ▪ BMF-219 was tested in two type 2 diabetic in-vivo models at clinically relevant exposures. BMF-219 treatment in STZ-induced diabetic rat model: ➢ Improved glucose metabolism (OGTT AUC reduction 41%, p<0.05) and reduction in blood lipemic levels and body weight. Minimal efficacy for pioglitazone. ➢ BMF-219 but not pioglitazone increased HOMA-B. BMF-219 treatment in ZDF rat model: ➢ Significant reduction (~50%) in fasting and non-fasting blood glucose levels, ➢ Significant reduction in serum insulin, C-peptide (p<0.05), and HOMA-IR (p<0.001) after two weeks of treatment. ➢ Prolonged glycemic control as evidenced by decreased OGTT glucose levels on day 15 (AUC reduction of 54%, p<0.001) and on day 29 (AUC reduction of 40%, p<0.05, ~2 weeks after the last dose). ➢ Significant reductions in blood lipemic levels (p<0.01) and body weight. ▪ Next Steps: Type 1 Model– Can BMF-219 re-establish Beta Cells from a severely diminished pool? 22
