Foghorn Provides Pipeline Update on FHD-909 BRM Selective Inhibitor

CAMBRIDGE, Mass., Feb. 08, 2024 (GLOBE NEWSWIRE) — Foghorn^® Therapeutics Inc. (Nasdaq: FHTX), a clinical-stage biotechnology company pioneering a new class of medicines that treat serious diseases by correcting abnormal gene expression, today announced that Lilly has selected FHD-909, a first-in-class oral BRM selective inhibitor, for clinical development. Lilly plans to file an IND for FHD-909 in Q2 2024. The primary target patient population is BRG1 mutated non-small cell lung cancer (NSCLC).

Selective BRM inhibition has been a sought-after objective in cancer research for many years. A variety of tumor types, including NSCLC, are known to have mutations in BRG1, which we believe make them dependent on BRM activity for their survival. Selective blocking of BRM activity is considered a promising strategy for causing tumor cell death while sparing healthy cells.

In December 2021, Foghorn announced a strategic collaboration with Lilly to create novel oncology medicines. The collaboration includes a US 50/50 co-development and co-commercialization agreement for Foghorn’s Selective BRM oncology program and an additional undisclosed oncology target. In addition, the collaboration includes three discovery programs using Foghorn’s proprietary Gene Traffic Control platform.

The Companies plan to present preclinical data at upcoming scientific conferences.

About FHD-909
FHD-909 is a highly potent, allosteric and orally available small molecule that selectively inhibits the ATPase activity of BRM over its closely related paralog BRG1, two proteins that are the catalytic engines across all forms of the BAF complex, one of the key regulators of the chromatin regulatory system. In preclinical studies, tumors with mutations in BRG1 rely on BRM for BAF function. FHD-909 has shown significant anti-tumor activity across multiple BRG1-mutant lung tumors.
