― Preclinical data of FTX-6274 suggests potential for the treatment of castration resistant prostate cancer ―

CAMBRIDGE, Mass., Oct. 14, 2025 (GLOBE NEWSWIRE) -- Fulcrum Therapeutics, Inc. ® (Fulcrum) (Nasdaq: FULC), a clinical-stage biopharmaceutical company focused on developing small molecules to improve the lives of patients with genetically defined rare diseases, today announced that it will present preclinical data for FTX-6274, an oral embryonic ectoderm development, or EED, inhibitor, in castration-resistant prostate cancer. Fulcrum will present these data at the ESMO Congress 2025 being held October 17-21, 2025, in Berlin, Germany.
