Fulcrum Therapeutics, Inc. is a clinical-stage biopharmaceutical company. The Company is focused on improving the lives of patients with genetically defined rare diseases in areas of high unmet medical need. The Company’s clinical product candidate, losmapimod, is developed for the potential treatment of facioscapulohumeral muscular dystrophy (FSHD). Its other clinical product candidate is FTX-6058, which is developed for the treatment of certain hemoglobinopathies, including sickle cell disease (SCD). In addition to product candidate development, the Company has developed a drug discovery approach that it employs to systematically identify and validate cellular drug targets that can potentially modulate gene expression to treat known root causes of genetically defined rare diseases. The Company has developed pociredir, which is designed to elevate the level of fetal hemoglobin, or HbF, for the treatment of people with SCD.
