CAMBRIDGE, Mass., May 15, 2023 (GLOBE NEWSWIRE) -- Fulcrum Therapeutics, Inc.® (the “Company”) (Nasdaq: FULC), a clinical-stage biopharmaceutical company focused on improving the lives of patients with genetically defined rare diseases, today reported financial results for the first quarter 2023 and provided a business update.

“With today’s announcement of Alex as our next CEO and President, Fulcrum has ended the first quarter of 2023 in a position of strength and with great promise for the future,” said Robert J. Gould, Ph.D., Fulcrum’s interim president and chief executive officer. “We continue to engage in productive dialogue with the FDA, as we work diligently to address the clinical hold for FTX-6058. Additionally, we remain on track to complete enrollment in the Phase 3 REACH trial in the second half of 2023, which will bring us one step closer to potentially delivering the first FDA-approved therapy for FSHD patients.”

Key Business Updates

FTX-6058

• On February 23, 2023, the FDA placed the investigational new drug (IND) application for FTX-6058 for the potential treatment of SCD on full clinical hold.
  • In its communication, the Agency noted preclinical data previously submitted in April, October and December 2022, a response to an early February 2023 information request from the FDA about data that we submitted in mid-February 2023, and non-clinical and clinical evidence of hematological malignancies observed with other inhibitors of polycomb repressive complex 2 (PRC2).
  • Active discussions with the Agency regarding the clinical hold of FTX-6058 are ongoing.
• Initial data reported in March 2023 but obtained prior to the clinical hold showed a 10.0% absolute fetal hemoglobin (HbF) increase from baseline in one subject in the 12 mg dose cohort of the Phase 1b clinical trial in SCD, resulting in a total HbF level of 24.9% after 42 days of treatment.
• FTX-6058 was generally well-tolerated, as of the March 2023 data cutoff date, with no drug-related treatment emergent serious adverse events and no discontinuations due to treatment emergent adverse events.
  
  

Losmapimod

• Enrollment is ongoing in the REACH Phase 3 pivotal trial evaluating losmapimod in FSHD at sites in the United States, Canada and Europe.
• On track to complete enrollment in the second half of 2023.
  
  

Corporate Updates

• Announced that Alex C. Sapir will join as president and CEO, and member of the Fulcrum board of directors, effective July 1, 2023. Prior to assuming his new role, Mr. Sapir will serve as Special Advisor to the interim president and CEO, effective May 12, 2023.  
• Completed underwritten public offering of common stock in January 2023, raising approximately $117.3 million in net proceeds.
• Esther Rajavelu resigned as chief financial officer, effective April 21, 2023. Ms. Rajavelu is serving in a consulting role to ensure the continuity of Fulcrum’s financial operations.
  
  

First Quarter 2023 Financial Results

• Cash Position: As of March 31, 2023, cash, cash equivalents, and marketable securities were $297.8 million, as compared to $202.9 million as of December 31, 2022.
• Collaboration Revenue: Collaboration revenue was $0.3 million for the first quarter of 2023 as compared to $2.6 million for the first quarter of 2022.
• R&D Expenses: Research and development expenses were $16.7 million for the first quarter of 2023 as compared to $17.8 million for the first quarter of 2022. The decrease of $1.1 million was primarily due to decreased research and development headcount, partially offset by increased costs associated with the advancement of REACH.
• G&A Expenses: General and administrative expenses were $11.5 million for the first quarter of 2023 as compared to $10.8 million for the first quarter of 2022. The increase of $0.7 million was primarily due to increased stock-based compensation expense.
• Net Loss: Net loss was $24.8 million for the first quarter of 2023 as compared to $25.9 million for the first quarter of 2022.
  
  

Financial Guidance

Fulcrum expects that its existing cash, cash equivalents, and marketable securities will be sufficient to fund its operating expenses and capital expenditure requirements into mid-2025.

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 (SCD) and other hemoglobinopathies, which is currently under a full clinical hold issued by the U.S. Food and Drug Administration. 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. For more information, visit www.fulcrumtx.com and follow us on Twitter @FulcrumTx and LinkedIn.

About FTX-6058
FTX-6058 is an investigational oral small-molecule inhibitor of Embryonic Ectoderm Development (EED) that was discovered using FulcrumSeek™, Fulcrum’s proprietary discovery engine. Inhibition of EED leads to potent downregulation of key fetal globin repressors, including BCL11A, thereby causing an increase in fetal hemoglobin (HbF). FTX-6058 is being developed for the treatment of sickle cell disease (SCD) and other hemoglobinopathies. Initial data in SCD demonstrated proof-of-concept and achieved absolute levels of HbF increases associated with potential overall patient benefit. Through the March 2023 data cutoff date, FTX-6058 has been generally well-tolerated in people with SCD with up to three months of exposure, with no serious treatment-emergent adverse events reported. FTX-6058 has been granted U.S. Food and Drug Administration (FDA) Fast Track designation and Orphan Drug Designation for the treatment of SCD. FTX-6058 is currently under a full clinical hold issued by the FDA.

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. People with SCD 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 Losmapimod
Losmapimod is a 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 Phase 2b ReDUX4 trial demonstrated slowed disease progression and improved function, including positive impacts on upper extremity strength and functional measures 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 3,600 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. Losmapimod is currently being evaluated in a Phase 3 multi-center randomized, double-blind, placebo-controlled, 48-week parallel-group study in people with FSHD (NCT05397470).

About FSHD
FSHD is a serious, rare, progressive and debilitating disease for which there are no approved treatments. It is characterized by fat infiltration of skeletal muscle leading to muscular atrophy involving primarily the face, scapula and shoulders, upper arms, and abdomen. Impact on patients includes profound decreases in the ability to perform activities of daily living, loss of upper limb function, loss of mobility and independence and chronic pain. FSHD is one of the most common forms of muscular dystrophy and has an estimated patient population of 16,000 to 38,000 in the United States alone.
