COVALENT-211 Phase II enrolling insulin-deficient type 2 diabetes patients

COVALENT-212 Phase II enrolling type 2 diabetes patients uncontrolled with a GLP-1 receptor agonist-based therapy

Topline 26-week primary endpoint data from both Phase II studies anticipated 4Q 2026

SAN CARLOS, Calif., March 31, 2026 (GLOBE NEWSWIRE) -- Biomea Fusion, Inc. ("Biomea" or "Biomea Fusion" or "the Company") (NASDAQ:BMEA), a clinical-stage diabetes and obesity medicines company, today announced that the first patient has been dosed in its newly initiated Phase II programs, COVALENT-211 and COVALENT-212, evaluating icovamenib in patients with type 2 diabetes ("T2D"), marking a key step in advancing icovamenib into Phase II development in targeted patient populations failing standard-of-care therapies as established in the clinical trial COVALENT-111.

"These studies represent an important step forward as we advance icovamenib into later-stage Phase II development in the two clearly defined patient populations in which we had observed sustained glycemic improvements in our prior study. We are planning to enroll these two studies within the second quarter to achieve an initial readout before year-end." said Mick Hitchcock, Ph.D., Interim Chief Executive Officer and Board Member of Biomea Fusion. "The design of COVALENT-211 and COVALENT-212 is informed by the durability, safety profile, and subgroup responses observed in our Phase II COVALENT-111 study, where we saw clinically meaningful glycemic improvements following a limited 12-week course of therapy with effects sustained nine months post the dosing period. These studies address patients who would otherwise require insulin therapy as one of their next therapeutic choices while existing alternatives are no longer providing glucose control. We believe icovamenib can provide significant benefits to these patients."

Icovamenib's Phase II Diabetes Program - COVALENT-211 and COVALENT-212

COVALENT-211 (NCT07502495) is evaluating icovamenib in adult patients with insulin-deficient T2D who are not achieving glycemic targets despite antihyperglycemic medications. Eligible participants must be on a stable dose of one to three antidiabetic therapies for at least three months prior to screening, with HbA1c levels between 7.5% and 10.5% and a body mass index (BMI) of ≤32 kg/m². Icovamenib is administered as an add-on to stable background therapy, which is maintained throughout the study unless rescue therapy is required.

COVALENT-212 (NCT07502508) is evaluating icovamenib in adult patients with T2D who remain inadequately controlled while receiving GLP-1 ("RA")-based therapy but have not achieved glycemic targets. Eligible participants must be on a stable dose of GLP-1 therapy for at least three months prior to screening and may receive up to two additional background therapies (metformin and/or an SGLT2 inhibitor). Participants must have HbA1c levels ≥7.5% and ≤9.5% and a BMI between 25 and 40 kg/m². Icovamenib is administered as an add-on to stable GLP-1 RA-based therapy, which is maintained throughout the study unless rescue therapy is required.

Both studies are planned to enroll approximately 60 participants each (2:1 randomization; icovamenib to placebo) across approximately 20 clinical sites. Participants will receive icovamenib 100 mg once daily or placebo for 12 weeks, followed by a 40-week off-treatment period designed to assess durability of glycemic control and beta-cell function beyond the dosing period, assessed at Week 26 (primary endpoint) and at Week 52 (secondary endpoint).

Both studies incorporate key learnings from the Phase II COVALENT-111 study, including optimized dosing informed by the COVALENT-121 food-effect study and a focus on patient populations that demonstrated the most pronounced and durable responses. Topline data from both studies are anticipated in the fourth quarter of 2026. Together, these studies are designed to evaluate icovamenib's potential to restore beta-cell function across two clinically distinct, high-need T2D populations.

Rationale for Targeted Patient Populations

The initiation of COVALENT-211 and COVALENT-212 builds on findings from the all-comers Phase II COVALENT-111 study in patients with T2D not achieving glycemic targets despite standard-of-care therapy. The data demonstrated durable and clinically meaningful reductions in HbA1c that persisted nine months after completion of a 12-week treatment course. The findings in the 52-week analysis include:

In patients with severe insulin-deficient T2D receiving one or more antihyperglycemic agents at baseline, icovamenib achieved up to a placebo-adjusted 1.5% mean reduction in HbA1c (p=0.01) that was maintained through Week 52 following 12 weeks of dosing.
In a subgroup of patients receiving GLP-1 RA-based therapy who had not achieved glycemic targets at study entry, icovamenib achieved a 1.8% placebo-adjusted mean reduction in HbA1c (p=0.05) that was maintained through Week 52 following 12 weeks of dosing.
In both populations, icovamenib treatment was associated with increased C-peptide levels measured off treatment, supporting the proposed mechanism of action of restoration of beta-cell function.
Icovamenib was generally well tolerated across all dosing arms, with no treatment-related serious adverse events or treatment discontinuations observed during the 52-week observation period.

These data support the continued development of icovamenib as a potential therapy designed to address underlying beta-cell dysfunction and provide durable glycemic control following a three-month treatment period.

About Icovamenib

Icovamenib is an orally administered investigational small molecule in Phase II clinical development for the treatment of diabetes. Icovamenib targets menin, a transcriptional regulator implicated in beta-cell dysfunction, and has been observed to induce transient reductions in menin protein levels in pancreatic islets, thereby modulating pathways associated with insulin secretion and glycemic control. As a potential short-course therapy, icovamenib could become an important addition to the diabetes treatment landscape, particularly addressing those patients who failed standard-of-care therapies.

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 ("T1D") (mediated by autoimmune dysfunction) and T2D (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 regulatory brake on beta-cell turnover and growth, supporting the hypothesis that menin inhibition may enable regeneration of functional cells. Based on these and other scientific findings, Biomea is exploring the potential for icovamenib-mediated menin inhibition as a viable therapeutic approach to potentially halt or reverse progression of T2D.

About Type 2 Diabetes

Diabetes is a chronic health condition that affects how the body turns food into energy and results in excessive glucose 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. According to the Centers for Disease Control and Prevention, more than 38 million Americans (~11% of the population) have diabetes, and 98 million adults have prediabetes. Diabetes also represents one of the largest economic burdens on the U.S. healthcare system, with approximately one in four healthcare dollars spent on diabetes care. Within the population of people with T2D, approximately one-third are insulin-dependent, a stage associated with increased complications such as kidney disease, nerve damage, vision loss, amputations and cardiovascular disease. People with insulin-deficient diabetes typically progress faster towards insulin-dependence. Insulin-deficient diabetes is a clinically recognized subtype characterized by impaired insulin secretion (significantly reduced beta-cell function). These patients typically present with higher HbA1c levels at diagnosis and lower BMIs. Separately, diabetes patients with higher BMIs often do not reach their glycemic targets even though treated with GLP-1RAs. Clinical research indicates that 20%-40% of people with T2D treated with GLP-1 RA-based therapies do not reach adequate levels of blood glucose control (HbA1c <7%) and often then progress to insulin-based regimens. Both of these populations, the insulin-deficient and GLP-1 non-responders, represent high unmet medical need and are inadequately served by current therapies.
