Biomea Fusion Reports Second Quarter 2023 Financial Results and Corporate Highlights

• Reported additional positive clinical data at ADA 83^rd Scientific Sessions from the first two cohorts of patients with type 2 diabetes from ongoing Phase I/II study (COVALENT-111) evaluating BMF-219 as a novel, potentially disease-modifying treatment candidate for patients with type 2 diabetes
  • New data highlighted specific patients treated with BMF-219 for 4 weeks maintained or experienced a further decrease in HbA1c levels 8 weeks after treatment was completed, up to a 2.4% reduction from baseline
  • BMF-219’s mechanism of action 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 2 diabetes, BMF-219 could be an important addition and complement to the treatment landscape, if approved   
• Reported initial topline data from ongoing Phase I clinical trial (COVALENT-101) showcasing initial responses in relapsed/refractory Acute Myeloid Leukemia (AML)
  • New data revealed 2 complete responses (CRs) out of 5 pretreated patients with relapsed/refractory AML patients carrying menin-dependent mutations (MLL1r, NMP1, MLL1-PTD, and NUP98 fusion) treated at Dose Level 4
  • BMF-219, the first and only investigational covalent small-molecule menin inhibitor in clinical development, was generally well tolerated with no dose-limiting toxicities observed, and no related QTc prolongation reported
• Continued enrolling four liquid tumor cohorts in ongoing Phase I study of BMF-219 (COVALENT-101), and three KRAS-mutated solid tumors in ongoing Phase I study of BMF-219 (COVALENT-102)
• Continued advancing second product candidate, BMF-500, a novel third generation covalent inhibitor of fms-like tyrosine kinase 3 (FLT3), toward the clinic; initiated a Phase I study of BMF-500 (COVALENT-103)

REDWOOD CITY, Calif., July 31, 2023 (GLOBE NEWSWIRE) -- Biomea Fusion, Inc. (“Biomea” or “the Company”) (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, reported second quarter 2023 financial results and business highlights.

“At the American Diabetes Association Annual Meeting in June, data presented from the COVALENT-111 study demonstrated for the first time how our investigational agent, BMF-219, may control blood glucose for diabetes patients 8 weeks after treatment had been completed,” said Thomas Butler, CEO and Chairman of Biomea. “The loss of mass and function of beta cells is an underlying cause of type 2 diabetes. We have now demonstrated from our clinical data to date, that inhibiting menin with BMF-219, may represent a new and important mechanism of action with lasting benefits for patients with type 2 diabetes. Our goal at Biomea is to develop a treatment that can halt or reverse disease progression in patients with type 1 and type 2 diabetes. A restored pool of healthy beta cells may allow patients to increase insulin production and achieve glycemic control while being off therapy. Our aspiration with BMF-219 is to help millions of type 2 diabetes patients break free from the current treatment paradigm in which, regardless of which currently approved treatments they take, their disease generally continues to progress.”

Mr. Butler further explained, “An orally delivered drug that, if approved, could restore healthy, functional, insulin-producing beta cells in type 2 diabetes patients would become a critical complement to nearly any currently approved therapies and, over time, could become an important standalone treatment. We look forward to continuing to evaluate BMF-219’s proposed mechanism of action and its potential therapeutic impact as this study progresses. Momentum for our diabetes program continues to build rapidly as the team executes at a high level. Our oncology programs are also gaining momentum as we approach target exposure in COVALENT-101 and COVALENT-102, our blood cancer and solid tumor studies.”

Second Quarter 2023 Clinical and Regulatory Highlights

DIABETES

• COVALENT-111 (BMF-219 for Diabetes)
  • BMF-219 is an investigational diabetes therapy that is aimed at reversing disease progression in patients with Type 1 or Type 2 Diabetes.
  • Reported new clinical data from the first two cohorts of the ongoing Phase II study (COVALENT-111) at the American Diabetes Association (ADA) 83rd Scientific Sessions. Patients received BMF-219 in each cohort for four weeks with or without food and were then followed for 22 weeks after treatment (n=12 per cohort with 10 patients receiving 100 mg BMF-219 once daily and 2 patients receiving placebo). As reported, eight weeks after completing treatment with BMF-219, patients with type 2 diabetes showed an increase of C-peptide and an improvement of HOMA-B, measured during oral glucose tolerance testing (OGTT), supporting improved beta cell function for these patients.
    • For Cohort 3 (100 mg BMF-219 QD without food for 4 weeks)
      • 50% of patients (n=5/10) saw a continued improvement in HbA1c with a mean reduction in HbA1c of 1.49% at Week 12, compared to the mean reduction of 0.9% at the end of the dosing period at Week 4 (an additional 62% HbA1c reduction)
      • 60% (n=6/10) of patients achieved an HbA1c of 7% or below at the end of Week 12, compared to 30% (n=3/10) at the end of dosing period (Week 4) and 10% (n=1/10) at the end of Week 1
      • The average C-peptide expression for patients in Cohort 3 increased through Week 8. A similar increase in HOMA-B was observed, stabilizing at Week 8
      • As measured by continuous glucose monitoring (CGM), 7 of 10 (70%) of patients maintained or improved time in range while off treatment (between Week 4 and Week 12)
    • BMF-219 demonstrated encouraging tolerability data with no dose reductions, or discontinuations. No patients showed symptomatic hypoglycemia, significant changes in hemoglobin levels. During the off-treatment period (Week 4 to Week 12), no severe or serious TEAEs were noted. As reported in March 2023, during the 4-week dosing period, in Cohorts 2 and 3 (100 mg QD, n=20; Placebo, n=4), 2 of 20 patients treated with BMF-219 showed mild (Grade 1) related treatment emergent adverse events (TEAEs) compared to no related TEAEs in 4 patients treated with placebo.
    • BMF-219 is an investigational diabetes therapy which showed initial improvements in glycemic control during and after cessation of treatment.
  • Anticipated Upcoming Milestones:
    • Complete dose escalation in COVALENT-111 (YE 2023)
    • Initiate dose expansion portion of COVALENT -111 (Q1 2024)
    • Initiate a clinical trial in Type 1 Diabetes patients (Q1 2024)

ONCOLOGY

• COVALENT-101 (BMF-219 for Oncology)
  • Reported initial topline data from ongoing Phase I clinical trial (COVALENT-101) showcasing initial responses in relapsed/refractory AML patients with menin-dependent mutations.
    • New data revealed 2 CRs out of 5 relapsed/refractory AML patients carrying menin-dependent mutations treated at Dose Level 4
    • BMF-219, the first and only investigational covalent small-molecule menin inhibitor in clinical development, was generally well tolerated with no dose-limiting toxicities observed, and no QTc prolongation reported
    • Dose Level 4 exposure correlates with initial activity seen in BMF-219’s pre-clinical studies
    • Safety profile of BMF-219 supports further dose escalation; enrollment for Dose Level 5 has commenced to explore the optimal biological dose
  • BMF-219 is the first investigational menin inhibitor in clinical development to be evaluated as a potential therapeutic agent in hematologic malignancies outside of MLL1r and NPM1 mutated AML/ acute lymphoblastic leukemia (ALL) patients, specifically in subsets of diffuse large B-cell lymphoma (DLBCL), multiple myeloma (MM) and chronic lymphocytic leukemia (CLL).
  • Continued site activation and patient enrollment to establish optimal dose levels across four liquid tumor cohorts including patients with AML/ALL, DLBCL, MM and CLL.
  • Anticipated Upcoming Milestones:
    • Report additional details of this clinical data set of AML/ALL patients dosed in the COVALENT-101 study at an upcoming medical conference
• COVALENT-102 (BMF-219 for KRAS-Mutant Solid Tumors)
  • BMF-219 is the first investigational menin inhibitor in clinical development for the treatment of solid tumors. A targeted pan-KRAS inhibitor could have the potential to treat 25-35% of NSCLC, 35-45% of CRC, and approximately 90% of PDAC patients.
  • Continued site activation and patient enrollment to establish optimal dose levels across all three solid tumor indications (NSCLC, CRC and PDAC with an activating KRAS mutation).
• COVALENT-103 (BMF-500 for Acute Leukemias)
  • BMF-500 is an investigational oral covalent inhibitor of FLT3, designed and developed in-house, and the second investigational compound discovered by Biomea’s FUSION™ System.
