Reported initial topline data of BMF-219 in ongoing Phase I clinical trial (COVALENT-101), showing 2 complete responses (CRs) out of 5 relapsed/refractory AML patients with menin-dependent mutations at Dose Level 4, with encouraging tolerability and safety data
Announced the appointment of Juan Pablo Frías, M.D., a prominent diabetes clinical development expert as Chief Medical Officer to oversee Biomea’s progressing clinical development of novel covalent menin inhibitor BMF-219 in type 2 and type 1 diabetes
Cash position of $199.5 million at the end of the third quarter of 2023

REDWOOD CITY, Calif., Oct. 30, 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 third quarter 2023 financial results and business highlights.

“With the disease modifying potential demonstrated by BMF-219, we are excited to begin the expansion portion of COVALENT-111 in type 2 diabetes, and to initiate the evaluation of BMF-219’s impact in type 1 diabetes with our COVALENT-112 study. Both studies are now open for enrollment more than a quarter ahead of schedule. With the potential to enable patients to retain and regenerate their own insulin-producing beta cells, BMF-219 may represent a promising new approach, if ultimately approved. We believe BMF-219 has the potential to halt and reverse disease progression for people with both type 1 and type 2 diabetes, enabling them to improve glycemic control while being off therapy and avoid insulin dependency,” said Thomas Butler, CEO and Chairman of Biomea. “In the third quarter, we also announced the first clinical data of BMF-219 in relapsed/refractory AML patients with menin-dependent mutations, which we believe yield encouraging efficacy and safety data. Finally in this quarter, we also initiated the clinical study of our second, Biomea-discovered investigational covalent inhibitor, BMF-500, a novel FLT3 inhibitor. We look forward to reporting on our pipeline progress in both diabetes and oncology in the upcoming quarters.”

THIRD QUARTER 2023 CLINICAL AND REGULATORY HIGHLIGHTS

DIABETES

COVALENT-111 (BMF-219 for Type 2 Diabetes)
- BMF-219 is an investigational diabetes therapy that in an early clinical trial has shown promising blood glucose control in adults with uncontrolled type 2 diabetes at Week 12, after 4 weeks dosing and 8 weeks off treatment.
- During the escalation phase of COVALENT-111, a total of 32 type 2 diabetes patients completed 4-weeks of dosing with BMF-219 to date (10 active patients per arm, with dose levels 100 mg with food, 100 mg, 200 mg and 200 mg with food (n=2)). Compared to baseline, 84% of all patients dosed for four weeks with BMF-219 showed a reduction in HbA1c at Week 4 and 74% at Week 12 (n=32), two months after the final dose of BMF-219. During the 4-week dosing period, BMF-219 was generally well tolerated; there were no dose reductions, dose discontinuations, or severe or serious adverse events. Also, during the off-treatment period, no severe or serious treatment emergent adverse events were noted.
- FDA and Health Canada cleared the initiation of the expansion portion of COVALENT-111, which will evaluate BMF-219 administered at 100 mg and 200 mg, with dosing durations up to 12 weeks in approximately 200 type 2 diabetes patients.
- Anticipated Upcoming Milestones:
  - Report topline data for the escalation portion in Q4 2023 to include multiple BMF-219 dosing cohorts (n=10 per cohort: 50 mg, 100 mg, 200 mg, 100 mg BID, 100 mg with food, and 200 mg with food (n=2)).
  - Start enrollment of expansion portion of COVALENT-111 at two dose levels including 100 mg and 200 mg, with a fourth cohort following the completion of the escalation portion.
COVALENT-112 (BMF-219 for Type 1 Diabetes)
- BMF-219 has shown the potential to specifically regenerate and retain insulin-producing beta cells in preclinical studies.
- Announced FDA clearance of IND for Phase II study COVALENT-112 of BMF-219 in type 1 diabetes. The study is designed to enroll 150 adults with type 1 diabetes and examine the safety and efficacy 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.
- Anticipated Upcoming Milestones:
  - Dose the first patient in COVALENT-112.

ONCOLOGY

COVALENT-101 (BMF-219 for Oncology)
- Reported initial topline data from ongoing Phase I clinical trial (COVALENT-101) which showcased initial responses in relapsed/refractory AML patients with menin-dependent mutations.
  - New data revealed 2 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 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 the 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; as a pan-KRAS inhibitor BMF-219 is under evaluation in subsets of NSCLC, CRC, and 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)
- Dosed first patient with BMF-500, a novel investigational third generation oral covalent inhibitor of FLT3 and the second product candidate discovered and developed by Biomea’s proprietary FUSION™ System.

FUSION^TM SYSTEM PLATFORM / ONGOING EFFORTS

Continued to advance development candidates derived from Biomea’s proprietary FUSION™ System platform to discover novel covalently binding small molecules. Both BMF-219 and BMF-500 were discovered via the FUSION™ System, each within 18 months from target identification to IND candidate selection.

THIRD QUARTER 2023 FINANCIAL RESULTS

Cash, Cash Equivalents, Restricted Cash, and Investments: As of September 30, 2023, the Company had cash, cash equivalents, restricted cash, and investments of $199.5 million, compared to $113.4 million as of December 31, 2022.

Net loss attributable to common stockholders was $82.4 million for the nine months ended September 30, 2023, compared to a net loss of $56.5 million for the same period in 2022.
Research and Development (R&D) Expenses: R&D expenses were $25.3 million for the three months ended September 30, 2023, compared to $18.2 million for the same period in 2022. The increase of $7.1 million was primarily due to an increase clinical development cost and external consulting related to the Company’s product candidates, BMF-219 and BMF-500, as well as increase in personnel-related costs. R&D expenses were $71.7 million for the nine months ended September 30, 2023 compared to $42.2 million for the same period in 2022. The increase of $29.5 million was primarily due to an increase personnel-related costs as well as an increase in clinical development and manufacturing costs related to the Company’s product candidates, BMF-219 and BMF-500.
General and Administrative (G&A) Expenses: G&A expenses were $5.8 million for the three months ended September 30, 2023, compared to $5.2 million for the same period in 2022. G&A expenses were $17.1 million for the nine months ended September 30, 2023 compared to $15.2 million for the same period in 2022. The increase in both periods was primarily due to increased personnel-related expenses, including stock-based compensation, due to an increase in headcount.
