Fulcrum Therapeutics Announces Multiple Presentations During the 62nd American Society of Hematology (ASH) Annual Meeting and ExpositionScreening of healthy volunteers initiated in Phase 1 clinical trial of FTX-6058

CAMBRIDGE, Mass., Nov. 04, 2020 (GLOBE NEWSWIRE) -- Fulcrum Therapeutics, Inc. (Nasdaq: FULC), a clinical-stage biopharmaceutical company focused on improving the lives of patients with genetically defined rare diseases, today announced it will present multiple posters on the company’s IND-supporting preclinical studies with its Embryonic Ectoderm Development (EED) inhibitor, FTX-6058, for hemoglobinopathies such as sickle cell disease and β-thalassemia during the virtual 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, December 5-8, 2020.

“We believe FTX-6058 has the potential to offer a differentiated approach for the treatment of hemoglobinopathies like sickle cell disease and β-thalassemia,” said Owen B. Wallace, Ph.D., Fulcrum’s chief scientific officer. “By demonstrating clinically desirable elevations of fetal hemoglobin up to approximately 30% of total hemoglobin in preclinical studies, these data, and those from our completed IND-enabling studies with FTX-6058, are incredibly exciting. We are pleased to present our preclinical proof-of-concept findings at this important scientific meeting and look forward to our clinical trial of FTX-6058 in healthy volunteers.”

Fulcrum will present three posters describing the potential of FTX-6058 to treat hemoglobinopathies during the following virtual sessions:

About FTX-6058
FTX-6058 is a highly potent small molecule inhibitor of Embryonic Ectoderm Development (EED) capable of inducing robust HbF protein expression in cell and murine models. Fulcrum believes the pharmacokinetics and human dose simulations support that FTX-6058 may be given as a once daily oral compound. The validation of EED as a target for sickle cell disease and the discovery of FTX-6058 as a novel HbF-inducing small molecule were conducted using Fulcrum’s proprietary Product Engine. Preclinical data with FTX-6058 showed an increase in HbF levels up to approximately 30% of total hemoglobin. Fulcrum has initiated a Phase 1 trial with FTX-6058 in healthy volunteers.

About Sickle Cell Disease
Sickle cell disease (SCD) is a genetic disorder of the red blood cells caused by a mutation in the HBB gene. This gene encodes a protein that is a key component of hemoglobin, a protein complex whose function is to transport oxygen in the body. The result of the mutation is less efficient oxygen transport and the formation of red blood cells that have a sickle shape. These sickle shaped cells are much less flexible than healthy cells and can block blood vessels or rupture leading to anemia. SCD patients typically suffer from serious clinical consequences, which may include anemia, pain, infections, stroke, heart disease, pulmonary hypertension, kidney failure, liver disease and reduced life expectancy.

About Fulcrum Therapeutics 
Fulcrum Therapeutics is a clinical-stage biopharmaceutical company focused on improving the lives of patients with genetically defined rare diseases in areas of high unmet medical need. Fulcrum’s proprietary product engine identifies drug targets which can modulate gene expression to treat the known root cause of gene mis-expression. The company has advanced losmapimod to Phase 2 clinical development for the treatment of facioscapulohumeral muscular dystrophy (FSHD) and Phase 3 for the treatment of COVID-19. Fulcrum has also advanced FTX-6058, a small molecule designed to increase expression of fetal hemoglobin for the treatment of sickle cell disease and beta thalassemia, into Phase 1 clinical development.
