Primary target patient population for the FHD-909 Phase 1 trial is non-small cell lung cancer (NSCLC)
Lilly leads the clinical development of the Phase 1 trial
Foghorn's selective SMARCA2 oncology program is part of a U.S. 50/50 co-development and co-commercialization collaboration with Lilly
CAMBRIDGE, Mass., Oct. 10, 2024 (GLOBE NEWSWIRE) -- October 10, 2024 -- 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 the first patient has been dosed with FHD-909 (LY4050784) in the Phase 1 trial for SMARCA4 (BRG1) mutated cancers, with non-small cell lung cancer (NSCLC) as the primary target patient population. FHD-909 is a first-in-class oral, highly potent compound that demonstrates high selectivity for SMARCA2 (BRM) over SMARCA4, a closely related protein.
"FHD-909 is the first SMARCA2 selective inhibitor to enter the clinic. Dosing the first patient marks an important milestone for the program and our collaboration with Lilly," said Adrian Gottschalk, President and Chief Executive Officer of Foghorn. "FHD-909 has high selectivity over closely related SMARCA4, offering a promising synthetic lethality strategy for prevalent SMARCA4 mutations and their sensitivity to SMARCA2 inhibition in NSCLC and other solid tumors. We look forward to continued advancement of FHD-909 in partnership with Lilly."
A Phase 1 open-label, multicenter trial will assess the safety, tolerability and initial efficacy of FHD-909 in patients with locally advanced or metastatic solid tumors harboring a SMARCA4 alteration.
Preclinical studies support that FHD-909 is a potent and selective SMARCA2 inhibitor with robust anti-tumor monotherapy activity. In vivo, FHD-909 has demonstrated favorable tolerability with dose-dependent modulation of SMARCA2 target genes, as well as robust and dose-dependent tumor growth inhibition and regression as a monotherapy in SMARCA2 mutant xenograft mouse models.
In December 2021, Foghorn announced a strategic collaboration with Lilly to create novel oncology medicines. The collaboration includes a U.S. 50/50 co-development and co-commercialization agreement for Foghorn's Selective SMARCA2 oncology program and an additional undisclosed oncology target. The collaboration also includes three discovery programs using Foghorn's proprietary Gene Traffic Control® platform.

About FHD-909
FHD-909 (LY4050784) is a potent, first-in-class, allosteric and orally available small molecule that selectively inhibits the ATPase activity of SMARCA2 (BRM) over its closely related paralog SMARCA4 (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 SMARCA4 rely on SMARCA2 for BAF function. FHD-909 has shown significant anti-tumor activity across multiple SMARCA4 mutant lung tumor models.
