CAMBRIDGE, Mass., Nov. 10, 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 provided a business update and reported financial results for the third quarter of 2020.

“We’ve made significant progress in 2020, which will lead to a number of key data readouts as we move into 2021,” said Robert J. Gould, Ph.D., president and chief executive officer. “We plan to announce full data from our ReDUX4 trial with losmapimod in facioscapulohumeral muscular dystrophy (FSHD), including the primary endpoint in the second quarter of 2021. We are encouraged by the interim analysis from ReDUX4, which assessed reductions in DUX4-driven gene expression, the root cause of the disease, via muscle biopsy. The full data will also contain a number of validated and novel endpoints and we look forward to presenting a comprehensive assessment of the data in its entirety. Our select hemoglobinopathy program, FTX-6058, a highly potent small molecule EED inhibitor, has made important progress as well, and we are currently screening healthy volunteers in our Phase 1 trial. We believe FTX-6058 has the potential to offer a transformative small molecule treatment option that could represent a significant development for sickle cell patients.”

“I am also pleased to report that Curtis Oltmans will be joining Fulcrum as Senior Vice President, General Counsel and Kim Hazen has been promoted to Senior Vice President, Human Resources,” continued Dr. Gould. “In addition, Alan Ezekowitz, MBChB, D.Phil will take on the responsibility of clinical advisor as Diego Cadavid, MD is leaving his position as Senior Vice President, Clinical Development. Curt has an extensive record of legal and corporate development accomplishments. Kim has made important contributions since joining Fulcrum in 2017 and Alan has served on our Board of Directors since 2016. We are thrilled to have them on our leadership team. We thank Diego for his many contributions to Fulcrum.”

Third Quarter and Recent Business Highlights

• Announced interim data for ReDUX4, a Phase 2b trial of losmapimod, a selective p38α/β mitogen activated protein kinase (MAPK) inhibitor, in FSHD.
  • Encouraging data suggest that muscles with the highest DUX4-driven gene expression in pre-treatment biopsies showed large reductions in DUX4-driven gene expression following treatment with losmapimod compared to placebo.
  • Remain on track to report full data in the second quarter of 2021. Data will include the primary endpoint, reduction from baseline of DUX4-driven gene expression, as well as a pre-specified sensitivity analysis assessing biopsies with the highest pre-treatment level of DUX4-driven gene expression, in addition to secondary and exploratory endpoints.
  • Continued evaluation of the Open Label Study and ReSOLVE Natural History Study
• On track to begin dosing healthy volunteers in a Phase 1 trial for sickle cell disease with FTX-6058 before year-end 2020.
  • FTX-6058, a highly potent small molecule EED inhibitor, is designed to induce expression of fetal hemoglobin (HbF) in red blood cells to compensate for the mutated adult hemoglobin for the potential treatment of hemoglobinopathies, including sickle cell disease and beta-thalassemia.
  • Preclinical data with FTX-6058 showed an increase in HbF levels up to approximately 30% of total hemoglobin showing the potential to have a significant impact on the sickle cell patient population.
  • Fulcrum’s non-provisional composition of matter patent application covering FTX-6058 and related structures published.
• Enrolling patients in the international, multicenter Phase 3 trial with losmapimod for hospitalized subjects with COVID-19 (LOSVID).

About FSHD
FSHD is characterized by progressive skeletal muscle loss that initially causes weakness in muscles in the face, shoulders, arms and trunk, and progresses to weakness throughout the lower body. Skeletal muscle weakness results in significant physical limitations, including an inability to smile and difficulty using arms for activities, with many patients ultimately becoming dependent upon the use of a wheelchair for daily mobility.

FSHD is caused by mis-expression of DUX4 in skeletal muscle, resulting in the presence of DUX4 proteins that are toxic to muscle tissue. Normally, DUX4-driven gene expression is limited to early embryonic development, after which time the DUX4 gene is silenced. In people with FSHD, the DUX4 gene is turned “on” as a result of a genetic mutation. The result is death of muscle and its replacement by fat, leading to skeletal muscle weakness and progressive disability. There are no approved therapies for FSHD, one of the most common forms of muscular dystrophy, with an estimated patient population of 16,000 to 38,000 in the United States alone.

About Losmapimod
Losmapimod is a selective p38α/β mitogen activated protein kinase (MAPK) inhibitor that was exclusively in-licensed from GSK by Fulcrum Therapeutics following Fulcrum’s discovery of the role of p38α/β inhibitors in the reduction of DUX4 expression and an extensive review of known compounds. Utilizing its internal product engine, Fulcrum discovered that inhibition of p38α/β reduced expression of the DUX4 gene in muscle cells derived from patients with FSHD. Researchers at Fulcrum also believe that losmapimod has the potential to treat COVID-19 by reducing the acute exaggerated pro-inflammatory responses to SARS-CoV-2 infection and restoring the antigen-specific immune responses needed for viral clearance, potentially leading to improved clinical outcomes. Losmapimod has been evaluated in more than 3,600 subjects in clinical research across multiple indications, including in several Phase 2 trials and a large Phase 3 trial in acute myocardial infarction. No safety signals were attributed to losmapimod in any of these trials. In 2020, the Company received U.S. and European Orphan Drug Designation for losmapimod for the treatment of FSHD. Fulcrum is currently conducting Phase 2 trials investigating the safety, tolerability, and efficacy of losmapimod to treat the root cause of FSHD and a Phase 3 trial investigating the safety, tolerability, and efficacy of losmapimod to treat hospitalized patients with COVID-19.

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 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) 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.
