Foghorn Therapeutics to Present New Preclinical Data for BRG1/BRM Inhibitor FHD-286 in Combination with Anti-PD-1 Antibody at Society for Immunotherapy of Cancer 37th Annual Meeting

CAMBRIDGE, Mass., Nov. 09, 2022 (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 new preclinical data for its FHD-286 program will be highlighted in a poster presentation at the Society for Immunotherapy of Cancer’s (SITC) 37th Annual Meeting. The meeting will be held November 812, 2022, at the Boston Convention and Exhibition Center and virtually.

New preclinical data will be presented on FHD-286, a potent and selective BRG1/BRM inhibitor, which is currently in Phase 1 clinical trials for the treatment of metastatic uveal melanoma (UM) and for relapsed and/or refractory acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). The poster will highlight new data demonstrating the potential of FHD-286, in combination with an anti-PD-1 antibody, to provide synergistic efficacy and survival benefit compared to anti-PD-1 alone in preclinical models.

Presentation Details
Title: Synergistic Efficacy of the BRM/BRG1 ATPase inhibitor, FHD-286, and anti-PD-1antibody in mouse syngeneic tumor models
Abstract Number: 888
Date: Friday, November 11, 2022
Time: 9:00 a.m. – 8:30 p.m. ET

The poster will be accessible following the presentation under the Science section of the Company’s website.

About FHD-286
FHD-286 is a highly potent, selective, allosteric and orally available, small-molecule, enzymatic inhibitor of BRG1 (SMARCA4) and BRM (SMARCA2), two highly similar proteins that are the ATPases, or the catalytic engines of the BAF complex, one of the key regulators within the chromatin regulatory system. In preclinical studies, FHD-286 has shown anti-tumor activity across a broad range of malignancies including both hematologic and solid tumors. The Phase 1 clinical trial in UM is actively enrolling patients. The Phase 1 clinical trial in AML and MDS is currently on full clinical hold. To learn more about these studies please visit ClinicalTrials.gov. (Link here for metastatic uveal melanoma and here for AML and MDS).

About AML
Adult acute myeloid leukemia (AML) is a cancer of the blood and bone marrow and the most common type of acute leukemia in adults. AML is a diverse disease associated with multiple genetic mutations. It is diagnosed in about 20,000 people every year in the United States.

About Uveal Melanoma
Uveal (intraocular) melanoma (UM) is a rare eye cancer that forms from cells that make melanin in the iris, ciliary body, and choroid. It is the most common eye cancer in adults. It is diagnosed in about 2,000 adults every year in the United States and occurs most often in lightly pigmented individuals with a median age of 55 years. However, it can occur in all races and at any age. UM metastasizes in approximately 50% of cases, leading to very poor prognosis.
