About Diabetes
Diabetes is a chronic health condition that affects how the body metabolizes nutrients. It results in too much glucose (sugar) in the bloodstream. Over time, this can cause serious health problems by damaging vital tissues and organs. Most people with diabetes have a shorter life expectancy than people without this disease. The Centers for Disease Control (CDC) estimates about 2 in 5 adults in the USA will develop diabetes during their lifetime, more than 37 million Americans of all ages (about 11% of the US population) have diabetes today and an additional 96 million adults (more than 1 in 3) have prediabetes, glucose levels 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 health care system, with $1 out of every $4 in US health care costs being spent on caring for people with diabetes.
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 elevated glucose levels (hyperglycemia).
There are two major types of diabetes: type 1 diabetes (T1D) and type 2 diabetes (T2D). T1D is caused by an autoimmune reaction (the body “attacks itself” by mistake). This reaction destroys insulin-producing beta cells in the pancreas, stopping the body’s ability to produce and secrete insulin. Approximately 5-10% of the people who have diabetes have T1D. With T2D, the body doesn’t use insulin well and can’t keep blood sugar at normal levels. About 90-95% of people with diabetes have T2D. Loss of functional beta-cell mass is a core component of the natural history in both T1D and T2D.
Despite significant advances in pharmacotherapy and diabetes-related devices over the past 2 decades, it is estimated that approximately 50% of persons with diabetes in the US do not have adequate glucose control, as defined by a glycated hemoglobin (HbA1C) of 7% or less. One important reason is that current agents for the management of T2D and T1D do not address the root cause of diabetes – a progressive decline in beta-cell mass and function.
Menin in Diabetes
Menin is a transcriptional scaffold protein that controls the expression and activity of proteins that regulate beta-cell proliferation. Menin is thought to control beta-cell proliferation and mass by acting 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, which could be a disease-modifying approach to treat diabetes.

BMF-219 – Potential Mechanism of Action
BMF-219, is an orally bioavailable, potent and selective covalent inhibitor of menin, built using Biomea Fusion’s FUSION™ System. The molecule is designed to regenerate insulin-producing beta cells with the aim to cure 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 beta cell death) and type 2 diabetes (mediated by metabolic dysfunction leading to beta cell death). 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 and growth, supporting the notion that inhibition of menin could lead to the regeneration of normal, healthy beta cells.
BMF-219’s proposed mechanism of action in diabetes is to enable the proliferation, preservation, and reactivation of a patient’s own healthy, functional, insulin-producing beta cells. As the potentially first disease-modifying therapy for type 1 and type 2 diabetes, BMF-219 could be an important addition and complement to the diabetes treatment landscape, if approved.
Preclinical Development
Biomea conducted two diabetes animal experiments to measure the potential impact of BMF-219 for the treatment of type 2 diabetes: the Zucker Diabetic Fatty (ZDF) rat, a widely studied model of obesity and insulin resistance in rats, and the Streptozotocin (STZ)-induced diabetic rat, another frequently used model in which diabetes is induced using a chemical (STZ) that selectively destroys beta cells. In both models, BMF-219 was able to normalize glucose levels in the majority of animals after just 2 weeks of treatment. Notably, the majority of the effect was maintained even after the two week BMF-219 treatment period. (Butler et al, EASD 2022; Somanath et al. EASD 2022)
In additional preclinical studies, ex vivo human pancreatic islet cultures were performed to assess the effect of BMF-219. Dependent on the concentration and duration of exposure, BMF-219 was shown to increase the beta-cell mass and function, promoting glucose-dependent proliferation and enhancement of insulin production. Beta cell proliferation was observed only under elevated glucose conditions, which mimic diabetic levels, and with continuous drug exposure. BMF-219 was demonstrated to upregulate the expression of key proteins involved in cell-cycle regulation such as PbK and CCNA2 (Cyclin A2) in a glucose-dependent fashion. (Kulkarni et al. WCIRDC 2023)

About Type 2 Diabetes
According to the International Diabetes Foundation, worldwide over 500 million adults have diabetes growing to over 600 million within this decade. In the United States alone, approximately 35 million adults have diabetes and over 90 million adults have pre-diabetes. Type 2 Diabetes is one of the largest economic burdens on the US health care system and the 7th leading cause of death in the US (Source: Diabetes.org) The prevalence of type 2 diabetes is increasing rapidly, particularly among younger age groups. Estimates suggest that people with type 2 diabetes die, on average, 6 years earlier than people without diabetes (Source: The Lancet. 2023 Sept). Despite increased research efforts over the past decades and with over 60 approved therapies to date, diabetes remains unresolved for almost 50% of patients on standard of care (source Clin Diabetes. 2020 Jul).
COVALENT-111 (Type 2 Diabetes)
Clinical Design and Results
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 volunteers were enrolled in single ascending dose cohorts to evaluate safety at the prospective dosing levels for patients with type 2 diabetes. Phase II consists of multiple ascending dose cohorts and includes adult patients with type 2 diabetes uncontrolled by standard of care medicines. The dose escalation phase evaluated BMF-219 dosed over 4 weeks with 22 weeks follow-up off treatment. Following the Escalation Phase of COVALENT-111, the study has advanced into an Expansion Phase (n>200) consisting of multiple cohorts dosing type 2 diabetes patients for longer dose durations. The first three arms (A, B, C) of the expansion phase are evaluating BMF-219 dosed over 8 and 12 weeks at 100 mg and 200 mg with up to 40 weeks of follow-up off treatment. 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.
Biomea reported initial clinical data from the first two cohorts of the Phase 2 portion of the T2D trial COVALENT-111 (NCT05731544) in March 2023:
- 89% of patients enrolled in Cohort 3 (n=10 patients at 100 mg dosed daily without food for 4 weeks) achieved a reduction in HbA1c, with 78% achieving ≥ 0.5% reduction and 56% achieving ≥ 1% reduction (median and mean reduction over the entire cohort: -1.0% and -0.81%, respectively).
- BMF-219 was well tolerated and demonstrated a favorable safety profile with no dose discontinuations.
Additional clinical data were presented in June 2023 at the annual meeting of the American Diabetes Association (ADA) from the first two cohorts of patients with T2D enrolled in the Phase 2 portion of COVALENT-111 (Rodriguez et al. ADA 2023):
- This new data highlighted specific patients treated with BMF-219 for 4 weeks who maintained or experienced a further decrease in HbA1c levels 8 weeks after treatment was completed, highlighting up to a 2.4% reduction from baseline.
In December 2023 at the World Congress Insulin Resistance Diabetes & Cardiovascular Disease (WCIRDC), Biomea presented long-term follow-up data showing improved glycemic control after 22 weeks off treatment in the ongoing COVALENT-111 study of BMF-219 in T2D (Frias et al. WCIRDC 2023):
- At Week 26 – 22 weeks following the last dose of BMF-219 – participants in the 100 mg QD (dosed without food) cohort saw a placebo-adjusted mean reduction in HbA1c of 0.8% (compared to a 0.7% placebo-adjusted mean reduction in HbA1c at Week 4, immediately after the completion of BMF-219 dosing).
- The observed HbA1C reduction was supported by an increase from baseline in placebo-adjusted mean HOMA-B (+270%) and in mean stimulated C-peptide AUC (+22%) at Week 26 in responders (defined as those T2D subjects achieving HbA1c reduction ≥0.5% at Week 26) and with baseline HOMA-B below the upper limit of normal of <200).
- BMF-219 was generally well tolerated; there were no dose reductions, dose discontinuations, or severe or serious adverse events, and no symptomatic or asymptomatic hypoglycemia was observed.
- In addition, Biomea reported that the 200 mg BMF-219 dosing cohorts nearly doubled the percentage of patients (~36%) achieving durable HbA1c reduction of 1% or more compared to the 100 mg cohorts, reported earlier at 20%.
Biomea presented additional clinical data sets from the dose escalation phase of COVALENT-111 in March 2024 at ATTD, highlighting BMF-219’s novel mechanism of action in patients with T2D (Rodriguez et al. ATTD 2024, Abitbol et al. ATTD 2024, Denham et al. ATTD 2024):
- Patients in COVALENT-111 displayed improving glycemic control while off therapy, supporting enhanced pancreatic islet function following BMF-219 treatment.
- Consistent with the mechanism of action, 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 only a 28-day dosing cycle of BMF-219, a general dose-response association was observed with placebo-adjusted mean percent changes of HbA1c of -0.04% (50mg QD*), -0.2% (100mg QD with food), -0.8% (100mg without food), -0.4% (200mg QD), -0.4% (100mg BID), and -1.4% (200mg with food) (*50mg data out to Week 20, at the time of data cut).
- Across 100mg QD, 200mg QD, and 100mg BID cohorts (N=40), 38% of patients had ≥0.5% HbA1c reduction (with a mean reduction of 1.2%), and 23% of patients had ≥1.0% HbA1c reduction (with a mean 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) following BMF-219 dosing at 200mg with food.
- Increases in HOMA-B and C-peptide generally correlated with glycemic control, consistent with BMF-219’s core mechanism of action: increased beta-cell proliferation and improved beta-cell function.
- 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.
- 100mg and 200mg BMF-219 dose levels have been selected for the first 3 Arms of the Expansion Phase of COVALENT-111, which will dose patients for up to 12 weeks (compared to 4 weeks in the Escalation Phase) and with extended off-treatment follow-up to Week 52.
About Type 1 Diabetes
Type 1 Diabetes is a growing disease burden in the US and globally and is associated with significant morbidity. Type 1 diabetes is a chronic autoimmune disease characterized by T-cell mediated destruction of insulin-producing pancreatic beta cells. The loss of beta-cell function requires exogenous insulin for metabolic control and survival. Insulin is the only approved therapy for T1D patients, with the risk of hypoglycemia, increased morbidity and mortality. Since the Discovery of Insulin in 1920’s, there Have Been Advances in Insulin Formulations, but no therapies that directly affect beta cells and their function.
COVALENT-112 (Type 1 Diabetes)
Clinical Design and Results
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 enrolling patients in a multi-arm trial comparing two different doses of BMF-219 to placebo (1:1:1) to evaluate the safety, tolerability, and efficacy of BMF-219 in adults 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 also includes an open-label portion for adults with type 1 diabetes up to 15 years since diagnosis. This Phase II a 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.
The first patient in the COVALENT-112 study was dosed at the end of December 2023. In April 2024, Biomea presented data from the first two type 1 diabetes patients enrolled in COVALENT-112, both of whom demonstrated early signs of clinical activity including improved measures of beta-cell function as indicated by c-peptide responses following initial treatment with BMF-219.

The review highlights the adaptive responses of beta-cells to the increased metabolic demands during gestation, emphasizing the importance of these mechanisms in maintaining maternal glucose homeostasis.
The article investigates the mechanisms of beta-cell compensation in the context of gestational diabetes mellitus (GDM). The authors explore how pregnancy induces adaptations in beta-cell function to meet increased insulin demands, emphasizing the role of compensatory mechanisms when insulin sensitivity is impaired. The review addresses the implications of these adaptations for the development and management of GDM, highlighting potential targets for therapeutic interventions aimed at preserving beta-cell function and improving maternal and fetal outcomes.
The study examines how serum obtained from pregnant individuals stimulates beta-cell proliferation and enhances insulin secretion in vitro. They utilize experimental models to demonstrate that factors present in pregnancy serum promote the growth and function of beta cells, potentially through signaling pathways involved in cellular proliferation and insulin synthesis.
The article investigates how prolactin, traditionally associated with lactation and reproductive functions, also plays a modulatory role in immune responses and pancreatic beta-cell function in T1D. They discuss experimental evidence suggesting that prolactin may exert protective effects on beta-cells, potentially reducing autoimmune destruction and preserving insulin production. The review proposes implications for therapeutic approaches aimed at modulating prolactin signaling to benefit individuals with T1D.
The study investigates how pregnancy and postpartum periods influence gene expression in different types of pancreatic islet cells. The authors use transcriptomic analysis to examine changes in alpha cells, beta cells, delta cells, and PP cells during these physiological stages. They explore how pregnancy alters the gene expression profiles of these cells, potentially affecting their functions related to hormone secretion and glucose metabolism regulation.
The author discusses the potential protective effect of breastfeeding against the development of diabetes. It highlights epidemiological evidence suggesting that breastfeeding is associated with a lower risk of both T2DM and GDM in women. The review emphasizes that breastfeeding may positively influence maternal glucose metabolism and insulin sensitivity postpartum, contributing to a reduced risk of diabetes later in life.
The study explores the relationship between lactation and the risk of developing T2DM in women with a history of GDM. The authors conduct a systematic review and meta-analysis and found that longer duration of breastfeeding is associated with a reduced incidence of T2DM in this population, suggesting a potential protective effect. The authors discuss mechanisms such as improved glucose metabolism and insulin sensitivity postpartum as contributing factors to this observed association.
The systematic review and meta-analysis synthesized findings from cohort studies to evaluate the impact of breastfeeding duration on T2DM risk post-GDM. Their analysis indicates that longer duration of lactation is associated with a reduced risk of developing T2DM following a pregnancy complicated by GDM. They discuss potential mechanisms such as improved insulin sensitivity and metabolic benefits conferred by breastfeeding.
The prospective cohort study investigates the relationship between lactation duration and the risk of developing T2DM following gestational diabetes mellitus GDM. The authors followed a cohort of women who had a history of GDM and found that longer duration of lactation is associated with a lower risk of developing T2DM. The study highlights that each additional year of breastfeeding was linked to a significant reduction in T2DM risk.
The study investigates the long-term impact of prior lactation on insulin sensitivity and the risk of developing diabetes by conducting a study to examine how past breastfeeding experiences influence metabolic health beyond the lactation period. They found that women with a history of breastfeeding exhibited improved insulin sensitivity compared to those who had not breastfed.
The study synthesized data from observational studies to assess how breastfeeding duration impacts maternal T2DM risk. Their analysis indicates that longer duration of lactation is associated with a lower risk of developing T2DM later in life.
