CAMBRIDGE, Mass., Nov. 07, 2023 (GLOBE NEWSWIRE) -- Fulcrum Therapeutics, Inc.® (“Fulcrum”) (Nasdaq: FULC), a clinical-stage biopharmaceutical company focused on developing small molecules to improve the lives of patients with genetically defined rare diseases, today reported financial results for the third quarter of 2023 and provided a business update.

“In the third quarter of 2023, we completed enrollment for the Phase 3 REACH trial of losmapimod and resolved the clinical hold for pociredir, bringing us one step closer to delivering on our mission to improve the lives of patients with rare genetic diseases,” said Alex C. Sapir, Fulcrum’s president and chief executive officer. “Building on this momentum, we remain focused on strong execution and believe we are now well-positioned to deliver on important clinical milestones, including topline data for REACH, which is expected in the fourth quarter of 2024. REACH is designed to demonstrate the potential of losmapimod to slow disease progression and address the debilitating effects of FSHD. We believe losmapimod could be the first approved treatment for this disease. With the clinical hold for pociredir lifted, we have been working diligently to resume enrollment in the Phase 1b trial for patients with SCD and look forward to building on the encouraging early clinical data observed to date. We remain very excited about pociredir’s potential to shift the current standard of care and importantly, offer a differentiated oral option.”

Recent Business Highlights

  • In September 2023, completed enrollment in REACH, a Phase 3 clinical trial evaluating losmapimod in patients with FSHD at sites in the United States, Canada, and Europe. The trial enrolled 260 patients. Fulcrum expects to report topline data in the fourth quarter of 2024. There are currently no approved treatments for FSHD.
  • In August 2023, the FDA lifted the clinical hold on the Investigational New Drug application for pociredir for the treatment of SCD.
    • The Phase 1b trial will be re-initiated at the 12 mg once daily dose (Cohort 3), which is expected to enroll approximately 10 patients, followed by an additional cohort of 10 patients at the 20 mg once daily dose (Cohort 4). The protocol was amended to revise the inclusion and exclusion criteria to target patients with higher disease severity. To learn more about the amended protocol and planned Phase 1b trial of pociredir, please see the program update presentation on Fulcrum’s website.

Third Quarter 2023 Financial Results

  • Cash Position: As of September 30, 2023, cash, cash equivalents, and marketable securities were $257.1 million, as compared to $202.9 million as of December 31, 2022.
  • Collaboration Revenue: Collaboration revenue was $0.8 million for the third quarter of 2023 as compared to $1.2 million for the third quarter of 2022.
  • R&D Expenses: Research and development expenses were $18.2 million for the third quarter of 2023 as compared to $15.4 million for the third quarter of 2022. The increase of $2.8 million was primarily due to increased costs associated with the advancement of REACH, including the completion of enrollment during September 2023.
  • G&A Expenses: General and administrative expenses were $10.0 million for the third quarter of 2023 as compared to $9.7 million for the third quarter of 2022. The increase of $0.3 million was primarily due to increased facilities, professional services, and software costs.
  • Net Loss: Net loss was $24.0 million for the third quarter of 2023 as compared to $23.7 million for the third quarter of 2022.

Updated Cash Runway Guidance

Fulcrum now expects that its existing cash, cash equivalents, and marketable securities will be sufficient to fund its operating requirements into 2026, an update to previous guidance of mid-2025.

About Fulcrum Therapeutics
Fulcrum Therapeutics is a clinical-stage biopharmaceutical company focused on developing small molecules to improve 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 in development for the treatment of facioscapulohumeral muscular dystrophy (FSHD), and pociredir (formerly known as FTX-6058), a small molecule designed to increase expression of fetal hemoglobin and in development for the treatment of sickle cell disease (SCD) and other hemoglobinopathies. Fulcrum uses proprietary technology to identify drug targets that can modulate gene expression to treat the known root cause of gene mis-expression. For more information, visit and follow us on Twitter@FulcrumTx and LinkedIn.

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 slower 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 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 relentless and accumulating muscle and functional loss impacting their 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.

About Pociredir
Pociredir is an investigational oral small-molecule inhibitor of Embryonic Ectoderm Development (EED) that was discovered using Fulcrum’s proprietary discovery technology. Inhibition of EED leads to potent downregulation of key fetal globin repressors, including BCL11A, thereby causing an increase in fetal hemoglobin (HbF). Pociredir is being developed for the treatment of 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. In clinical trials conducted prior to the clinical hold, pociredir was generally well-tolerated in people with SCD with up to three months of exposure, with no serious treatment-related adverse events reported. Pociredir has been granted U.S. Food and Drug Administration (FDA) Fast Track designation and Orphan Drug Designation for the treatment of SCD. To learn more about these trials please visit

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.
