CAMBRIDGE, Mass., March 03, 2022 (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 fourth quarter and full year of 2021.

“Our progress in 2021 has set us up for a tremendous 2022 with meaningful catalysts across our key programs,” said Bryan Stuart, president and chief executive officer. “We announced today that we have a clear regulatory path forward for a Phase 3 trial that we believe is optimized to show losmapimod’s potential to slow or stop the progression of FSHD. We are moving quickly to initiate the REACH trial in the second quarter of this year. We are also on track to report initial data from our Phase 1b with FTX-6058 in people with sickle cell disease. We believe a once-daily well-tolerated oral HbF inducer that can deliver robust increases in HbF over baseline could be life-changing. We are also on track to initiate a Phase 1b trial with FTX-6058 in other hemoglobinopathies, including beta thalassemia. With our cash runway into 2024, we are focused on delivering key data to support our goal of bringing therapies to people with rare genetic diseases.”

Upcoming Milestones

Losmapimod

• Initiate REACH, a Phase 3 randomized, double-blind, placebo-controlled multi-national trial to evaluate the efficacy and safety of losmapimod for the treatment of facioscapulohumeral muscular dystrophy (FSHD). The trial is expected to enroll approximately 230 adults with FSHD. Patients will be randomized 1:1 to receive either losmapimod, administered orally as a 15 mg tablet twice a day, or placebo, and evaluated over a 48-week treatment period. The primary endpoint of the trial is the absolute change from baseline in Reachable Workspace (RWS). Secondary endpoints include muscle fat infiltration (MFI), Patient Global Impression of Change (PGIC), and Quality of Life in Neurological Disorders of the upper extremity (Neuro QoL UE). The trial will also include patient-centered assessments of healthcare utilization.

FTX-6058

• Report initial data, including measures of HbF protein induction and safety, from the Phase 1b trial in people with sickle cell disease in the second quarter of 2022.
• Initiate Phase 1b trial in select other hemoglobinopathies, including beta-thalassemia, in the second quarter of 2022.
• Initiate registrational trial in sickle cell disease in early 2023.

Preclinical Pipeline

• Nominate next development candidate by end of 2022 to support the company’s fourth Investigational New Drug (IND) by the end of the first quarter of 2023.

Recent Business Highlights

• Engaged with U.S. and EU regulatory agencies, including the Food and Drug Administration (FDA), and gained alignment on key aspects of the design for a Phase 3 trial with losmapimod for FSHD.
• Received Orphan Drug Designation from the FDA for FTX-6058 in sickle cell disease.
• Dosed first patient with sickle cell disease in the Phase 1b clinical trial of FTX-6058, an oral fetal hemoglobin (HbF) inducer.
• Completed three-month preclinical toxicology studies and initiated chronic toxicology studies to advance FTX-6058 in multiple indications.
• Submitted IND application to initiate clinical development of FTX-6058 in non-SCD hemoglobinopathies, including beta-thalassemia.
• In December 2021, reported positive results from the Phase 1 trial in healthy adult volunteers treated with FTX-6058.
  • Data from the 20mg and 30mg dose cohorts demonstrated a mean 5.6-fold induction and a mean 6.2-fold induction in HBG mRNA, respectively, at day 14. These increases were higher than those observed in the previously reported 2, 6 and 10mg dose cohorts. In preclinical studies of FTX-6058, increases in HBG mRNA have consistently translated to the same fold increases in HbF protein. Notably, human genetics show that 2-3-fold increases in HbF are associated with significantly improved outcomes, and even functional cures, in people with sickle cell disease. FTX-6058 has now demonstrated a greater than 2-fold mean induction of HBG mRNA in healthy volunteers starting with the 6mg dose. To date, FTX-6058 has been generally well-tolerated with no serious adverse events reported.
• Advanced FulcrumSeek™ discovery efforts and strategic collaborations with Acceleron, a wholly owned subsidiary of Merck & Co., Inc., and MyoKardia, a wholly owned subsidiary of Bristol-Myers Squibb Company.
• Appointed Esther Rajavelu Fulcrum’s Chief Financial Officer in January 2022.
• Promoted Kim Hazen to Chief People Officer in January 2022.

About Losmapimod
Losmapimod is an investigational, selective p38α/β mitogen activated protein kinase (MAPK) inhibitor. Fulcrum exclusively in-licensed losmapimod from GSK following Fulcrum’s discovery of the role of p38α/β inhibitors in the reduction of DUX4 expression and an extensive review of known compounds. Results reported from the ReDUX4 trial demonstrated slowed disease progression and improved function, including positive impacts on upper extremity strength, supporting losmapimod’s potential to be a transformative therapy for the treatment of FSHD. Although losmapimod had never previously been explored in muscular dystrophies, it had been evaluated in more than 3,500 subjects in clinical trials across multiple other indications, with no safety signals attributed to losmapimod. Losmapimod has been granted U.S. Food and Drug Administration (FDA) Fast Track designation and Orphan Drug Designation for the treatment of FSHD.

About FSHD
FSHD is one of the most common forms of muscular dystrophy. It is a serious, rare, progressive and disabling disease for which there are no approved treatments and has an estimated patient population of 16,000 to 38,000 in the United States alone. FSHD is characterized by muscle degeneration and fat infiltration, initially affecting movement of the face and eventually the arms, trunk and legs. Disease progression results in accumulation of disability, with many patients ultimately becoming dependent upon the use of a wheelchair for daily mobility. Impact on patients includes decreased ability to perform activities of daily living, maintain independence, and lost ability to function or work.

About FTX-6058
FTX-6058, an EED inhibitor, is an investigational oral HbF inducer being developed for the treatment of sickle cell disease and other hemoglobinopathies, such as beta-thalassemia. The validation of EED as a target for sickle cell disease and the discovery of FTX-6058 was conducted using FulcrumSeek™. Results from a Phase 1 healthy volunteer trial demonstrated proof of biology and proof of mechanism, including robust induction of HBG mRNA after 14 days of dosing. To date, FTX-6058 has been generally well-tolerated with no serious adverse events reported.

About Sickle Cell Disease
Sickle cell disease 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. Sickle cell disease 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 two lead programs in clinical development are losmapimod, a small molecule for the treatment of facioscapulohumeral muscular dystrophy (FSHD) and FTX-6058, a small molecule designed to increase expression of fetal hemoglobin for the treatment of sickle cell disease and other hemoglobinopathies, including beta-thalassemia. The company’s proprietary product engine, FulcrumSeek™, identifies drug targets that can modulate gene expression to treat the known root cause of gene mis-expression.
