Biomea Fusion Reports Third Quarter 2026 Financial Results and Corporate Highlights

• Completed enrollment in the Phase II COVALENT-211 clinical trial evaluating icovamenib in patients with insulin-deficient type 2 diabetes (“T2D”); topline data expected in the first quarter of 2027
• Enrollment ongoing in the Phase II COVALENT-212 clinical trial evaluating icovamenib in patients with T2D not achieving glycemic targets on GLP-1 receptor agonist (“GLP-1 RA”)-based therapy; topline data expected in the second quarter of 2027
• Announced Phase I results for BMF-650, an investigational next-generation oral GLP-1 RA, that, demonstrated weight reduction over 28 days and a generally favorable tolerability profile
• First patient dosed in the Open Label Adaptive Platform (“OPAL”) trial evaluating icovamenib in combination with semaglutide, in collaboration with the University of Leicester
  • Cash runway projected into the second quarter of 2027

SAN CARLOS, Calif., Nov. 10, 2026 (GLOBE NEWSWIRE) — Biomea Fusion, Inc. (“Biomea” or “Biomea Fusion” or “the Company”) (Nasdaq: BMEA), a clinical-stage diabetes and obesity company, today reported its financial results for the third quarter ended September 30, 2026, and provided a business update.

“The third quarter was marked by meaningful execution across both of our clinical programs. We completed enrollment in our first diabetes Phase II clinical trial, COVALENT-211, and continue to advance enrollment in our Phase II COVALENT-212 clinical trial, bringing us closer to important Phase II data readouts for icovamenib in two distinct diabetes populations that we estimate represent over 30% of treated patients with diabetes in the U.S.,” – said Mick Hitchcock, Ph.D., Interim Chief Executive Officer of Biomea Fusion. “We also reported first-in-human results for BMF-650, providing initial clinical support for our design hypothesis, in that BMF-650 achieved meaningful weight reduction while limited GI side effects were observed, all of which were Grade 1 AEs at the highest dose level. Encouragingly, BMF-650 demonstrated weight reduction and a generally favorable tolerability profile with only one-step titration. We also made important progress with the OPAL trial, overseen by the Leicester Diabetes Centre, dosing the first patient evaluating icovamenib in combination with semaglutide. Together, we believe these accomplishments reinforce our confidence in our pipeline and position us for several important Phase II readouts in 2027.”

Recent Corporate Highlights:

Icovamenib

Potential First-in-Class Oral Small Molecule Product Candidate Targeting Menin

• Three Phase II clinical trials evaluating icovamenib in T2D and obesity are ongoing:
  • COVALENT-211: Completed enrollment in the Phase II, randomized, double-blind, placebo-controlled clinical trial evaluating icovamenib in patients with insulin-deficient T2D not achieving glycemic targets despite standard-of-care therapy. Primary endpoint data evaluating HbA1c reduction at Week 26 are expected in the first quarter of 2027.
  • COVALENT-212: Enrollment is ongoing in the Phase II, randomized, double-blind, placebo-controlled clinical trial evaluating icovamenib in patients with T2D not achieving glycemic targets on GLP-1 receptor agonist (“GLP-1 RA”) based therapy. Primary endpoint data evaluating HbA1c reduction at Week 26 are expected in the second quarter of 2027.
  • First patient has been dosed in the ongoing OPAL study in collaboration with the University of Leicester to evaluate icovamenib in a Phase II clinical trial in combination with semaglutide in obesity through a newly activated experimental arm of the Open Label Adaptive Platform Trial. The randomized, double-blind study will assess physical function, body weight, body composition, muscle health and metabolic outcomes, with the primary endpoint assessed at Week 24. Topline data is anticipated at the end of 2027.

BMF-650
Next-generation Oral Small Molecule GLP-1 RA Product Candidate for Obesity

• Announced Phase I GLP-131 clinical trial results for BMF-650, its investigational oral small molecule GLP-1 RA, that demonstrated consistent weight reduction across five multiple ascending dose (“MAD”) cohorts over four weeks and an encouraging tolerability profile, including rapid one-step titration to the 400 mg once-daily target dose.
• Across Cohorts 1-4, mean weight reduction ranged from 1.5% to 3.2% at Day 29, compared with 0.1% for pooled placebo. At doses of 200 mg or higher once daily, mean weekly weight reduction was approximately 0.97 kg.
• In Cohort 5, conducted under confinement to ensure dosing compliance and better characterize safety and tolerability, mean weight reduction was 6.1% (6.2 kg) at Day 29, averaging approximately 1.55 kg per week without observed attenuation during treatment. As confinement appeared to affect eating behavior, these results should be interpreted separately from outpatient Cohorts 1-4.
• BMF-650 was generally well tolerated across all five active-dose MAD cohorts (n=40) to date, with all reported treatment-emergent adverse events (“TEAEs”) being mild or moderate. There were no severe or serious TEAEs, TEAE-related dose modifications, or TEAE-related study discontinuations.
• In Cohort 5, rapid one-step titration from 200 mg to 400 mg once daily after one week demonstrated similar gastrointestinal tolerability to slower titration regimens. All reported TEAEs were mild, with nausea and vomiting each reported in 12.5% of Cohort 5 participants, supporting further evaluation of a potential “no titration” dosing regimen.
• Following completion of Phase I data collection, additional clinical development of BMF-650 will require longer-term toxicology studies. Biomea intends to continue this work while positioning the program for a potential strategic partnership, including licensing opportunities for late-stage development and commercialization.

Personnel-related expenses decreased by $1.0 million, including stock-based compensation, due to a decrease in headcount. Facilities and other allocated expenses decreased by $0.9 million due to a decrease in rent and facilities-related costs. R&D expenses were $26.8 million for the nine months ended September 30, 2026, compared to $53.9 million for the same period in 2025. The decrease of $14.8 million in external costs was primarily driven by a decrease of $4.6 million related to nonclinical and exploratory programs, a decrease of $4.2 million in other external costs related to consultants, advisors and other professional services to support our clinical studies, a decrease of $4.0 million related to clinical activities and a decrease of $2.0 million of manufacturing costs.

Facilities and other allocated expenses decreased by less than $0.1 million. G&A expenses were $11.7 million for the nine months ended September 30, 2026, compared to $15.7 million for the same period in 2025. The decrease of $4.0 million was primarily driven by a decrease of $3.1 million related to personnel-related expenses, including stock-based compensation, due to a decrease in headcount and a decrease of $0.7 million of corporate-related expenses. Facilities and other allocated expenses decreased by $0.2 million.
