Biomea Fusion, Inc. Reports Inducement Grant under Nasdaq Listing Rule 5635

Biomea Fusion, Inc. ("Biomea" or the "Company") (Nasdaq: BMEA), announced that the Company has received notice from the U.S. Food and Drug Administration (FDA) that a full clinical hold has been placed on Biomea's ongoing Phase III clinical trials of the Company's investigational covalent menin inhibitor BMF-219 in type 2 and type 1 diabetes (COVALENT-111 and COVALENT-112), respectively. The Company will continue ongoing safety and efficacy data collection during the hold.

"We respect the FDA's decision and agree that patient safety is paramount and our top priority. We are fully collaborating and working diligently with the FDA to put a plan in place as quickly as possible to ensure patient safety and look forward to resuming the studies once we have authorization from the FDA. The results to date have supported that BMF-219 is generally well-tolerated and can restore glucose-controlled insulin production and improve glycemic control. Based on the totality of the safety and efficacy data for BMF-219 in diabetes to date, we remain committed to advancing BMF-219 with its potentially transformative profile," stated Thomas Butler, Biomea Fusion's Chief Executive Officer and Chairman of the Board.

Biomea Fusion, Inc. ("Biomea") (Nasdaq: BMEA), a clinical-stage biopharmaceutical company dedicated to discovering and developing oral covalent small molecules to treat and improve the lives of patients with metabolic diseases and genetically defined cancers, today announced the completion of enrollment of the first three dose expansion arms of COVALENT-111, with a total of over 260 type 2 diabetes patients enrolled.

The COVALENT-111 study is a multi-site, randomized, double-blind, placebo-controlled Phase I/II study. Phase II consists of multiple dose escalation and dose expansion cohorts including adult patients with type 2 diabetes uncontrolled by standard of care medicines. The dose escalation phase is evaluating BMF-219 dosed over 4 weeks with 22 weeks follow-up off treatment. 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.

• Reported positive data from the escalation portion of Phase 1/2 study (COVALENT-111) in type 2 diabetes patients, displaying durable improved glycemic control while off therapy for 22 weeks, supporting the disease-modifying potential of BMF-219 to address a root cause of diabetes: a loss of healthy, insulin-producing beta cells
• Announced initial clinical data from our Phase 2 study (COVALENT-112) in type 1 diabetes from the first two type 1 diabetes patients dosed with BMF-219 and demonstrated early signs of clinical activity with improved measures of beta-cell function after initial treatment with BMF-219
• We expect a reduction in operating expenses in the second half of the year due to the near completion of enrollment of the first three arms of our type 2 diabetes study and near completion of enrollment of the open label portion of our type 1 diabetes study. Cash position of $145.3 million at the end of the first quarter of 2024

Biomea Fusion, Inc. ("Biomea" or "the Company") (Nasdaq: BMEA), a clinical-stage biopharmaceutical company dedicated to discovering and developing oral covalent small molecules to treat and improve the lives of patients with metabolic diseases and genetically defined cancers, reported first quarter 2024 financial results and corporate highlights.

"Over the last two months we have seen a significant increase in the rate of enrollment for the expansion phase cohorts of our Phase 1/2 study, COVALENT-111, investigating BMF-219 in patients with type 2 diabetes. There is currently a waitlist for the fourth cohort which we expect will open for enrollment in the second half of this year.  We have also seen a significant increase in the rate of enrollment of our Phase 2 study, COVALENT-112, in patients with type 1 diabetes following the press release which provided an early look at the first two patients dosed with BMF-219. Here we highlighted the first two patients dosed with BMF-219 demonstrated an increase in C-peptide Index (Amount of C-peptide secreted per unit of glucose) during the early stages of treatment. This is truly an exciting and validating update on our progress in type 1 diabetes. Patients with type 2 diabetes have lost about 50% of their pool of beta cells while patients with type 1 diabetes have lost at least 90% of their beta-cell pool at diagnosis and are therefore not able to produce sufficient insulin to address the glucose levels in their blood. Currently approved treatments for diabetes are mostly chronic treatments helping patients to reduce the blood glucose while the mass and function of the beta cells continues to decline. We have now demonstrated in multiple preclinical experiments that BMF-219 has the potential to address diabetes at the root cause level by improving the function and mass of beta cells. The data we reported from the escalation portion of our clinical study COVALENT-111 in the first quarter of 2024 demonstrated for the first time how an agent can achieve durable glycemic control while patients are off therapy, supporting the disease-modifying potential of BMF-219 to address a root cause of diabetes," stated Thomas Butler, Biomea Fusion's Chief Executive Officer and Chairman of the Board. "In 2024, we expect to continue to advance our clinical programs with BMF-219 in diabetes and plan to report multiple data readouts throughout the remainder of the year, including topline Week 26 data of over 200 patients from our Phase 1/2 study, COVALENT-111, in type 2 diabetes, and topline Week 26 data from approximately 40 patients enrolled in the open label portion of our Phase 2 study, COVALENT-112, in type 1 diabetes patients. Our goal is to deliver a short-term, non-chronic treatment that will reconstitute insulin-producing beta cells, allowing the patients' own bodies to normalize blood sugar levels."

Biomea Fusion, Inc. (Nasdaq: BMEA) ("Biomea" or the "Company"), a clinical stage biopharmaceutical company focused on the discovery and development of covalent small molecules to treat patients with genetically defined cancers and metabolic diseases, today announced that on May 1, 2024, the compensation committee of Biomea's board of directors granted 8 new employees non-qualified stock options to purchase an aggregate of 80,250 shares of the Company's common stock. The shares underlying each employee's stock options will vest 116 on a quarterly basis over four years, in each case subject to each such employee's continued employment with the Company on such vesting dates. All of the above-described awards were made under Biomea's 2023 Inducement Equity Plan (the "Plan").
