Key Takeaways from the Facioscapulohumeral Muscular Dystrophy Market
The market size for Facioscapulohumeral Muscular Dystrophy (FSHD) in the leading markets is expected to grow significantly by 2036.
The 7MM FSHD market is projected to increase substantially during the forecast period 2026–2036, driven by the anticipated launch of emerging disease-modifying therapies and increasing diagnosis rates.
In 2025, the United States accounted for approximately 45% of the total diagnosed FSHD cases across the 7MM, with patient numbers expected to increase through 2036.
In 2025, there were nearly 16,000 cases of FSHD1 and approximately 800 cases of FSHD2 in the United States.
According to McNiff et al. (2023), approximately 95% of patients are diagnosed with FSHD Type 1, while the remaining cases are classified as FSHD Type 2.
According to Sanson et al. (2022), the prevalence of FSHD is estimated to be approximately 1 in 8,000 to 1 in 15,000 in the United States and around 1 in 20,000 in both Italy and the United Kingdom.
According to the FSHD Society, FSHD1 accounts for nearly 95% of all cases, while FSHD2 represents the remaining 5% of patients.
According to the National Organization for Rare Disorders (NORD) (2020), FSHD affects males and females in relatively equal numbers, with an estimated prevalence of 4–10 cases per 100,000 individuals.
Leading FSHD companies, including Novartis, Roche, Chugai Pharmaceutical, Epicrispr Biotechnologies, Modalis Therapeutics, Restem, and others, are actively developing innovative therapies expected to transform the FSHD treatment landscape over the coming years.
Promising Facioscapulohumeral Muscular Dystrophy therapies in clinical development include Delpacibart braxlosiran (del-brax), GYM329/RO7204239/RG6237, EPI-321, MDL-103, Restem-L, and others.

Key Factors Driving the Facioscapulohumeral Muscular Dystrophy Market
Increasing Awareness and Improved Genetic Diagnosis
Growing awareness among healthcare professionals, improved availability of genetic testing, and enhanced understanding of the molecular basis of FSHD are facilitating earlier diagnosis and appropriate disease management. Increasing diagnosis rates are expected to expand the treated patient population and support market growth.
Rapid Advancement of Gene-targeted Therapies
The FSHD therapeutic pipeline has expanded considerably with multiple companies developing innovative therapies designed to suppress DUX4 expression, inhibit myostatin, and improve muscle strength and function. These disease-modifying approaches have the potential to significantly alter the treatment paradigm for FSHD.
Growing Investment in Rare Neuromuscular Disorders
Increasing investment from biotechnology and pharmaceutical companies, coupled with orphan drug incentives, strategic acquisitions, and advances in RNA-targeting and gene-editing technologies, is accelerating clinical development and creating substantial growth opportunities within the FSHD market.
Facioscapulohumeral Muscular Dystrophy Competitive Landscape
The current Facioscapulohumeral Muscular Dystrophy treatment landscape remains limited to supportive care, rehabilitation, pain management, and surgical interventions, as no disease-modifying therapy has yet received regulatory approval for FSHD. Current management primarily focuses on improving mobility, preserving muscle function, reducing complications, and enhancing patients’ quality of life through physical therapy, exercise programs, scapular fixation surgery, and symptomatic pharmacological treatment.
The competitive landscape is evolving rapidly with several promising therapies targeting the underlying genetic mechanisms of FSHD. Delpacibart braxlosiran (del-brax) is designed to suppress abnormal DUX4 expression through RNA-targeted therapy, while GYM329/RO7204239/RG6237 targets myostatin inhibition to improve muscle strength. Additional investigational therapies, including EPI-321, MDL-103, and Restem-L, are advancing through clinical development and represent significant opportunities to address the substantial unmet medical needs associated with this progressive neuromuscular disorder.

Recent Developments in the Facioscapulohumeral Muscular Dystrophy Market
In January 2026, Novartis completed its acquisition of Avidity Biosciences, strengthening its neuromuscular disease pipeline and gaining access to Delpacibart braxlosiran (del-brax), a promising RNA-targeted therapy for Facioscapulohumeral Muscular Dystrophy.
In December 2025, Restem announced that the first patient had been dosed in the Phase I/IIa clinical study evaluating Restem-L in patients with Facioscapulohumeral Muscular Dystrophy. The clinical trial is being supported through a partnership with SOLVE FSHD.
In August 2025, Epicrispr Biotechnologies announced dosing of the first patient in its global first-in-human Phase I/II clinical trial evaluating EPI-321, an investigational gene-modulating therapy designed to silence DUX4 expression through epigenetic modulation.
In October 2025, Avidity Biosciences reported that the Phase III FORTITUDE-3 trial evaluating Delpacibart braxlosiran (del-brax) is underway, with topline biomarker data expected in Q2 2026 and global regulatory submissions anticipated in 2028.
In September 2024, Fulcrum Therapeutics announced that the Phase III REACH trial evaluating losmapimod failed to meet its primary endpoint, leading the company to discontinue further development of the investigational therapy for FSHD.
What is Facioscapulohumeral Muscular Dystrophy?
Facioscapulohumeral Muscular Dystrophy (FSHD) is one of the most common inherited adult-onset muscular dystrophies, characterized by progressive weakness and wasting of the facial, shoulder-girdle, and upper-arm muscles. As the disease progresses, weakness may extend to the abdominal, pelvic-girdle, and lower-limb muscles, resulting in impaired mobility and reduced quality of life.
FSHD is primarily classified into FSHD Type 1 (FSHD1) and FSHD Type 2 (FSHD2). The disorder is caused by abnormal activation of the DUX4 gene, resulting from genetic alterations involving the D4Z4 repeat region on chromosome 4 or other associated genetic mechanisms. Symptoms commonly begin during the first or second decade of life, although disease onset and severity vary considerably among individuals. Diagnosis is based on clinical evaluation and confirmatory genetic testing. Currently, there is no approved disease-modifying therapy for FSHD, and treatment primarily focuses on rehabilitation, physical therapy, pain management, and supportive care to preserve mobility and functional independence.
