8-K: Foghorn Therapeutics Advances Pipeline with Multiple Clinical and Preclinical Programs

Foghorn Therapeutics is progressing its pipeline of first-in-class precision therapeutics, with multiple programs advancing into clinical trials and preclinical development.

Summary

• Foghorn Therapeutics is focused on developing novel cancer therapies by targeting chromatin biology, which is implicated in up to 50% of tumors.
• The company's pipeline includes FHD-286, a dual BRM/BRG1 inhibitor, which has shown differentiation in acute myeloid leukemia (AML) patients and is being evaluated in combination with decitabine.
• FHD-909, a selective BRM inhibitor partnered with Lilly, is on track for Phase 1 initiation, targeting BRG1 mutated cancers.
• Foghorn is also developing selective protein degraders for CBP, EP300, and ARID1B, with IND-enabling studies anticipated for CBP by the end of the year and EP300 in 2025.
• The company has a strategic collaboration with Lilly, including a $380 million upfront payment and a 50/50 U.S. economic split on two lead programs.
• Foghorn has $206.7 million in cash and equivalents as of March 31, 2024, and an additional $103.4 million net proceeds from a May 2024 financing, providing a cash runway into 2027.
• The company's platform is designed to deliver precision, first-in-class therapeutics by leveraging its expertise in chromatin biology, assays, biochemistry, and chemistry.

• The company faces competition from other companies in the biotechnology and pharmaceutical industries.
• The company's ability to attract and retain key scientific and management personnel is critical to its success.
• The company's business is subject to substantial risks and uncertainties, including macroeconomic and geopolitical factors.

Future Outlook

Foghorn anticipates data from the Phase 1 study of FHD-286 in combination with decitabine in H2 2024, and the Phase 1 initiation of FHD-909 in the second half of 2024. The company also plans to advance its preclinical assets towards IND filings, with a cash runway into 2027.

Management Comments

• Foghorn is the pioneer in chromatin biology, an untapped area for therapeutics.
• The company's Gene Traffic Control Platform is designed to deliver precision, first-in-class therapeutics.
• Foghorn is advancing a pipeline of first-in-class precision therapeutics with potential for broad application in oncology.

Industry Context

Foghorn is operating in the rapidly evolving field of cancer therapeutics, specifically targeting chromatin biology, which is an area of increasing interest. The company's approach to targeting previously undruggable targets and its strategic collaboration with Lilly position it as a potential leader in this space. The company is competing with other biotech and pharmaceutical companies developing novel cancer therapies.

Comparison to Industry Standards

• Foghorn's approach to targeting chromatin biology is unique compared to traditional cancer therapies that focus on specific mutations or pathways.
• The company's protein degrader platform is similar to other companies developing targeted protein degradation therapies, such as Arvinas and C4 Therapeutics, but Foghorn is focused on chromatin regulators.
• The collaboration with Lilly is a significant validation of Foghorn's technology and approach, similar to other large pharmaceutical companies partnering with smaller biotech firms to access innovative technologies.
• The clinical data for FHD-286 in AML is comparable to other novel therapies in development for this indication, such as menin inhibitors, but Foghorn's approach is broader and not limited to specific mutations.
• The development of selective inhibitors and degraders for CBP and EP300 is challenging, and Foghorn's progress in this area is notable compared to other companies that have struggled with selectivity and toxicity.

Stakeholder Impact

• Shareholders: The company's progress and financial stability are positive for shareholders.
• Employees: The company's growth and development provide opportunities for employees.
• Patients: The company's pipeline has the potential to address unmet needs in cancer treatment.
• Partners: The collaboration with Lilly is a positive development for both companies.
• Creditors: The company's strong cash position reduces the risk for creditors.

Next Steps

• Initiate Phase 1 clinical trial for FHD-909 in the second half of 2024.
• Advance preclinical assets (BRM Selective Degrader, CBP, EP300, ARID1B) towards IND filings.
• Release data from the Phase 1 study of FHD-286 in combination with decitabine in H2 2024.
• Continue to explore the potential of the Gene Traffic Control Platform for additional therapeutic targets.
