Biomea Fusion Reports First Quarter 2024 Financial Results and Corporate Highlights

• 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."

  DIABETES  

  COVALENT-111 (BMF-219 for Type 2 Diabetes)  

• Reported positive data from the escalation portion of Phase 2 study (COVALENT-111) in type 2 diabetes patients, supporting the disease-modifying potential of BMF-219 to address a root cause of diabetes: loss of healthy, insulin-producing beta cells.
  • After just a 4-week treatment period in type 2 diabetes patients, who had previously failed standard of care (HbA1c ≥7.0% and ≤10.5%), BMF-219 demonstrated continued glycemic control at 26 weeks, or five months, after cessation of dosing. Here, a durable glycemic response (≥1.0% HbA1C reduction) was seen in 20% and 36% of patients in once daily 100 mg and 200 mg cohorts, respectively.
   
  • A general dose response was observed from BMF-219 in type 2 diabetes patients supported by dose-dependent PK response. 50mg cohort had the lowest placebo adjusted mean percent change of A1c (-0.04%) while 200mg with food cohorts achieved the highest change of A1c (-1.4%).
   
  • BMF-219 was generally well tolerated with no serious adverse events and no adverse event-related study discontinuations, and no symptomatic or clinically significant hypoglycemia.
   
  • 100mg and 200mg dose levels have been selected for the first 3 Arms of the Expansion Phase, which will dose patients up to 12 weeks (compared to 4 weeks in the Escalation Phase) and extended follow-up to Week 52.
    
   
 

  Anticipated 2024 Milestones:  

• On track to complete 400 mg cohort from the Escalation Phase of COVALENT-111.
 
• On track to complete enrollment of the first three expansion cohorts of COVALENT-111 (n=216) in type 2 diabetes patients with poorly controlled diabetes and provide topline 26-week follow-up data.
 

  COVALENT-112 (BMF-219 for Type 1 Diabetes)  

• Announced initial data 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. BMF-219 was well tolerated by both patients.
  
 

  Anticipated 2024 Milestones:  

• On track to complete enrollment of the open label portion (n=40) of COVALENT-112 in type 1 diabetes dosed for 12 weeks with BMF-219 and provide topline 26-week follow-up data.
  
 

  ONCOLOGY  

  COVALENT-101 (BMF-219 for Liquid Tumors)  

  Anticipated 2024 Milestones:  

• On track to complete dose escalation portion of COVALENT-101 and establish recommended Phase 2 dose (RP2D).
  
 

  COVALENT-102 (BMF-219 for Solid Tumors)  

  Anticipated 2024 Milestones:  

• On track to complete dose escalation portion of COVALENT-102 and establish RP2D.
  
 

  COVALENT-103 (BMF-500 for Acute Leukemias)  

  Anticipated 2024 Milestones:  

• On track to complete dose escalation portion of COVALENT-103 and establish RP2D.
  
 

  FUSION   ^TM   SYSTEM DISCOVERY PLATFORM  

• Continued the development of the Biomea FUSION™ Platform technology.
  
 

  Anticipated 2024 Milestones:  

• On track to announce a third development candidate from the Biomea FUSION™ Platform technology.
  
 

  FIRST QUARTER 2024 FINANCIAL RESULTS  

•   Cash, Cash Equivalents, and Restricted Cash: As of March 31, 2024, the Company had cash, cash equivalents and restricted cash of $145.3 million, compared to $177.2 million as of December 31, 2023.
 
•   Net Income/Loss: The Company reported a net loss attributable to common stockholders of $39.1 million for the three months ended March 31, 2024, which included $5.0 million of stock-based compensation, compared to a net loss of $29.1 million for the same period in 2023, which included $3.2 million of stock-based compensation.
 
•   Research and Development (R&D) Expenses: R&D expenses were $33.8 million for the three months ended March 31, 2024, compared to $24.4 million for the same period in 2023. The increase of $9.4 million was primarily due to an increase in clinical and pre-clinical development cost and external consulting costs related to the Company's product candidates, BMF-219 and BMF-500, as well as an increase in personnel-related costs and facilities cost due to new lease agreements for additional office and laboratory space which commenced in 2023.
 
•   General and Administrative (G&A) Expenses: G&A expenses were $7.3 million for the three months ended March 31, 2024, compared to $5.6 million for the same period in 2023. The increase of $1.6 million was primarily due to increased personnel-related expenses, including stock-based compensation.
