    CAMBRIDGE, Mass., April 09, 2021 (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 presented the medicinal chemistry strategy for FTX-6058 at the First Time Disclosure Session at the American Chemical Society (ACS) Spring 2021 National Meeting. FTX-6058 is a highly potent orally bioavailable small molecule EED inhibitor for the potential treatment of select hemoglobinopathies, including sickle cell disease and β-thalassemia. The validation of EED as a fetal hemoglobin (HbF) inducer target for sickle cell disease was conducted using FulcrumSeek, Fulcrum’s proprietary product engine.

    “We are pleased to report progress on our development of FTX-6058 including the first publication of the structure of this compelling EED inhibitor,” said Chris Moxham, Ph.D., Fulcrum’s chief scientific officer. “We believe that this oral, once-a-day therapy with an impressive preclinical pharmacological profile has the potential to provide a meaningful therapeutic benefit to patients with sickle cell disease and β-thalassemia. We are also excited to report initial PK results from the SAD cohort and that our Phase 1 trial in healthy volunteers continues to progress with initiation of the multiple ascending dose cohorts. We expect to report the full data from this Phase 1 trial mid-year.”

    FTX-6058 inhibits PRC2 via binding to EED, which induces robust HbF protein expression in both cell and murine models. Increasing HbF has the potential to prevent or reduce disease-related pathophysiology and reduce the risk of recurring events such as vaso-occlusive crises and hemolysis. Preclinical data with FTX-6058 showed an increase in HbF levels up to approximately 30% of total hemoglobin, demonstrating the potential to have a significant impact in patients with sickle cell disease. Human genetic data further indicate that individuals with the sickle cell mutation and high HbF levels may have asymptomatic disease, underscoring the protective effect of increased HbF.

    Fulcrum’s Phase 1 trial in healthy volunteers is evaluating the safety, tolerability and pharmacokinetics of FTX-6058. Dosing has been initiated in the randomized, double-blind, placebo-controlled, multiple ascending dose (MAD) cohorts of the trial. Dosing continues in the single ascending dose (SAD) portion. The company anticipates sharing data from this Phase 1 trial in mid-2021 and initiating a clinical trial in sickle cell patients by the end of 2021.

    Today’s presentation, titled “Discovery of clinical candidate FTX-6058: a potent, orally bioavailable upregulator of fetal hemoglobin for treatment of sickle cell disease”, will be available in the “Publications” section of fulcrumtx.com.

    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 cells. 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 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 adult volunteers.

    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). 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.
