Foghorn Therapeutics Inc. announced that preclinical data for its pipeline programs, including the first presentation of preclinical data for FHD-909, a potential first-in-class BRM (SMARCA2) selective inhibitor will be presented at the 2024 American Association for Cancer Research (AACR) Annual Meeting being held April 5-10, 2024 in San Diego, California. In addition to the FHD-909 poster, the Company will have a symposium presentation, a town hall talk, and poster presentations on its selective CBP degrader and selective EP300 degrader programs. FHD-909 (a.k.a. LY4050784) is a highly potent, allosteric and orally available small molecule that selectively inhibits the ATPase activity of BRM (SMARCA2) over its closely related paralog BRG1 (SMARCA4), 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.
