Conference call scheduled for 8:00 a.m. ET today

CAMBRIDGE, Mass., May 13, 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 first quarter of 2020.

“Despite these unprecedented times, the first quarter was a period of important progress for Fulcrum and the fundamentals of our business remain strong,” said Robert J. Gould, Ph.D., president and chief executive officer. “I am proud of our continued commitment to patients and the dedication demonstrated by our employees in these challenging times. In the wake of COVID-19, a number of our clinical trial sites postponed their activities. Our team acted swiftly to minimize the health risks to patients, families and healthcare professionals involved in our studies of losmapimod in the treatment of facioscapulohumeral dystrophy (FSHD). We amended our Phase 2b trial, ReDUX4, to extend the trial from 24 to 48 weeks, added an interim analysis for subjects who underwent their 16-week biopsy as originally planned, and added a 36-week biopsy for patients who cannot undergo their 16-week biopsy. We believe these changes will enable patients and investigators to continue participation in the trial and will allow us to collect the essential data needed to evaluate the potential efficacy and safety of losmapimod for the treatment of FSHD.”

Recent Business Highlights

• Amended ReDUX4, a Phase 2b trial of losmapimod, a selective p38α/β mitogen activated protein kinase (MAPK) inhibitor, to accommodate COVID-19 impact; extended the trial from 24 to 48 weeks, adding a 36-week biopsy for those subjects unable to undergo their 16-week biopsy, and included an interim analysis on patients who completed their 16-week biopsy as planned in the original protocol.
  • ReDUX4 enrollment completed.
  • ReDUX4 open label extension initiated.
  • Data from interim analysis expected in the third quarter of 2020.
• Received U.S. and European Orphan Designation for losmapimod in FSHD.
• Completed investigational new drug application (IND)-enabling studies, including toxicology work with FTX-6058.
  • Remain on track to initiate Phase 1 trial in the second half of 2020.
  • FTX-6058 is an oral small molecule therapeutic discovered by Fulcrum and designed to induce expression of fetal hemoglobin (HbF) in red blood cells to compensate for the mutated adult hemoglobin in sickle cell disease.
• Presented evidence of dose-dependent target engagement observed in skeletal muscle with losmapimod 15 mg twice per day in a Phase 1 trial during the Muscular Dystrophy Association virtual clinical trials session.
  • Builds on previously announced dose-dependent pharmacokinetics and target engagement in blood.
• Continued evolution of Fulcrum’s proprietary product engine, which is designed to identify drug targets, programs and clinical development candidates in a broad range of genetically defined diseases (FulcrumSeek), and initiated research activities under the Acceleron collaboration.
  

ReDUX4 Trial Amendment
ReDUX4 is a randomized, double-blind, placebo-controlled multicenter international Phase 2b clinical trial in 80 subjects with FSHD to investigate the efficacy and safety of oral administration of losmapimod 15 mg twice per day. The primary endpoint is to evaluate the reduction of DUX4-driven gene expression in affected skeletal muscle biopsies. The original design of ReDUX4 included a muscle biopsy at week 16 during the 24-week treatment period followed by an open label extension. Twelve of the 80 subjects have completed the 24-week treatment period and rolled over to the open label extension portion of the trial.

As a result of the COVID-19 pandemic, Fulcrum has extended the trial from 24 to 48 weeks through a protocol amendment to ensure the safety of the subjects and to allow for the opportunity for a biopsy at week 16 as originally intended or at week 36. Approximately 68 subjects who did not complete the original 24-week treatment period remain active in the randomized portion of the trial. An interim analysis of approximately 25 subjects who completed their 16-week biopsy will be conducted. The Company expects to report data from this interim analysis in the third quarter of 2020. The extension from 24 to 48 weeks also allows for a longer assessment in a placebo-controlled design of the skeletal muscle MRI secondary endpoint and the various exploratory clinical endpoints, such as reachable workspace, FSHD-Timed Up and GO, muscle function measures and patient reported outcomes. Topline data from approximately 80 patients is expected in the first quarter of 2021. Fulcrum believes the amendment to the trial provides flexibility to address the challenges presented by the COVID-19 pandemic and supports collection of efficacy and safety data to support continued discussions with health authorities regarding potential registration strategies.

First Quarter 2020 Financial Results

• Cash Position: As of March 31, 2020, cash, cash equivalents, and marketable securities were $81.2 million, as compared to $96.7 million as of December 31, 2019. Based on its current plans, the Company expects that its existing cash, cash equivalents and marketable securities will be sufficient to enable it to fund its operating expenses and capital expenditure requirements into the third quarter of 2021.
  
• R&D Expenses: Research and development expenses were $14.5 million for the first quarter of 2020, as compared to $34.6 million for the first quarter of 2019. Research and development expenses for the first quarter of 2019 include $25.6 million of one-time costs incurred associated with the issuance of Series B convertible preferred stock under the Company’s license agreement with GSK for losmapimod. Excluding these one-time costs, the increase of $5.5 million was primarily due to increased costs related to the advancement of losmapimod for the treatment of FSHD, as well as increased personnel-related costs to support the growth of Fulcrum’s research and development organization.
  
• G&A Expenses: General and administrative expenses were $5.1 million for the first quarter of 2020, as compared to $2.6 million for the first quarter of 2019. The increase of $2.5 million was primarily due to increased personnel-related costs to support the growth of our organization, as well as increased consulting and professional fees associated with operating as a public company.
  
• Net Loss: Net loss was $18.5 million for the first quarter of 2020, as compared to a net loss of $36.8 million for the first quarter of 2019.

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. Although losmapimod has never previously been explored in muscular dystrophies, it has been evaluated in more than 3,500 subjects in clinical trials across multiple other indications, including in several Phase 2 trials and a Phase 3 trial. No safety signals were attributed to losmapimod in any of these trials. Fulcrum is currently conducting Phase 2 trials investigating the safety, tolerability, and efficacy of losmapimod to treat the root cause of FSHD.

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 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 has completed extensive preclinical research for FTX-6058 for the treatment of sickle cell disease and beta-thalassemia.
