Biomea Fusion, Inc. (“Biomea”) (Nasdaq: BMEA), a preclinical-stage biopharmaceutical company focused on the discovery and development of irreversible small molecules to treat patients with genetically defined cancers, reported financial results for the second quarter of 2021.

“We continue to make notable progress as we rapidly advance BMF-219 toward a planned entry into the clinic and continue to grow our company and pipeline,” said Thomas Butler, Biomea’s CEO and Chairman of the Board. “In the second quarter, we successfully completed IND-enabling studies for BMF-219 and are now in the final stages of completing our IND submission to the FDA to advance BMF-219 to a Phase I study for the treatment of patients with menin-dependent AML and ALL. We also continued to make important progress pursuing our broad, ambitious, preclinical strategy focused on exploring the potential of this novel irreversible small molecule across a number of menin-dependent liquid and solid tumors, including DLBCL.”

Mr. Butler continued, “While our primary focus is oncology drug development, there are multiple diseases where the menin pathway is implicated and where an irreversibly binding small molecule approach may have an important impact, including for patients with type 2 diabetes. At our core, we feel a profound responsibility to help patients with our novel chemistry. To that end, we look forward to seeing the results of our exploratory pathway validation in type 2 diabetes next year.”

Business Highlights

• Completed IND-enabling studies with irreversibly binding menin inhibitor BMF-219. Biomea successfully conducted IND-enabling studies with BMF-219, an irreversible menin inhibitor for the treatment of patients with menin-dependent AML and ALL. Biomea anticipates submitting the IND during the second half of 2021.
  
• Continued preclinical studies of BMF-219 in DLBCL. Biomea continues to explore the potential of BMF-219 for a number of menin-dependent liquid and solid tumor cancers, including a subset of DLBCL, with a number of preclinical studies currently underway. The Company plans to report its findings in DLBCL in the first quarter of 2022. Despite the high dependency of several cancers on menin, Biomea Fusion is not aware of any menin inhibitors currently in clinical development for these cancer types.
  
• Initiated pathway validation studies in diabetes. Based on a growing body of internal and external scientific evidence, Biomea has initiated key preclinical studies to explore the potential of its irreversible menin inhibitors as a treatment for type 2 diabetes. The Company plans to report its findings in the first quarter of 2022. Biomea Fusion is not aware of any menin inhibitors currently in clinical development for diabetes.
• Expanded team and in-house research capabilities to support long-term growth and clinical and preclinical development plans. Biomea strengthened its executive team with the appointments of Franco Valle as Chief Financial Officer, Alex Cacovean, M.D. as Executive Medical Director and Sasha Blaug Ph.D. as Senior VP of Corporate Development. Biomea has successfully grown its headcount this year to date by 29 for a total of 41 current team members. The Company has also completed the buildout of its own laboratory facilities to further support the research and preclinical pipeline development of its irreversible platform.
• Strengthened the Company’s Board of Directors. In the second quarter Biomea appointed Sumita Ray J.D., Chief Legal and Administrative Officer at Calithera Biosciences, Inc., to its Board. Ms. Ray is an industry veteran with over 20 years of expertise in FDA regulatory law, global health care law and compliance, brand support, product launches, collaborations and alliances.

Financial Highlights

Second Quarter 2021 Year to Date Financial Results

• Biomea reported a net loss attributable to common stockholders of $14.3 million for the first six months of 2021, compared to a net loss of $0.7 million for the same period in 2020.
  
  
• Research and development expenses were $9.0 million for the first six months of 2021, compared to $0.6 million for the same period in 2020. The increase of $8.4 million was primarily due to an increase in personnel-related expenses, as well as an increase in pre-clinical development costs, including manufacturing and external consulting, related to the IND-enabling studies for BMF-219.
  
  
• General and administrative expenses were $5.3 million for the first six months of 2021, compared to $0.1 million for the same period in 2020. The increase of $5.2 million was primarily due to higher personnel-related expenses and other corporate costs to support the Company’s expanding operations, including legal and accounting.
  
  
• As of June 30, 2021, the Company had cash, cash equivalents, restricted cash, and investments of $203.0 million.

About Biomea Fusion

Biomea Fusion is a preclinical-stage biopharmaceutical company focused on the discovery and development of irreversible small molecules to treat patients with genetically defined cancers. An irreversible small molecule drug is a synthetic compound that forms a permanent bond to its target protein and offers a number of potential advantages over conventional reversible drugs, including greater target selectivity, lower drug exposure and the ability to drive a deeper, more durable response. Leveraging its extensive expertise in irreversible binding chemistry and development, the Company built its proprietary FUSION System discovery platform to advance a pipeline of novel irreversible, small molecule therapies. The lead product candidate, BMF-219, is an orally bioavailable, potent and selective irreversible inhibitor of menin, an important transcriptional regulator known to play a direct role in oncogenic signaling in multiple cancers. In preclinical studies, administration of BMF-219 has resulted in robust anti-tumor responses across a range of liquid and solid tumor models and has been well-tolerated in animal studies. Biomea Fusion is developing BMF-219 for the treatment of liquid and solid tumors that are highly dependent on menin, including leukemias containing the mixed lineage leukemia (“MLL”) fusion protein. The Company is currently completing investigational new drug enabling studies and expects to file an IND application with the U.S. Food and Drug Administration in the second half of 2021. Additionally, literature has implicated menin inhibition as a potential therapeutic strategy for the treatment of various forms of diabetes, including type 2 diabetes. Biomea Fusion has initiated preclinical work to assess the potential of the menin pathway in type 2 diabetes and will report findings in the first quarter of 2022. Beyond BMF-219, the Company is utilizing its novel platform to develop irreversible treatments against other high-value oncogenic drivers of cancer and expects to nominate its second development candidate in the first half of 2022. Biomea Fusion’s goal is to utilize its capabilities and platform to become a leader in developing irreversible small molecules in order to maximize the depth and durability of clinical benefit when treating various cancers.
