Overview
Duchenne Muscular Dystrophy (DMD) is a severe and progressive genetic disorder that leads to muscle weakness and wasting. It primarily affects young boys and leads to significant disability and a reduced life expectancy. While there is currently no cure for DMD, research into genetic therapies, exon-skipping, cell therapies, and supportive treatments is improving outcomes and offering hope for individuals with DMD. DMD is caused by mutations in the dystrophin gene, which results in a lack of functional dystrophin protein that is essential for maintaining the integrity of muscle cells.
The treatment of Duchenne muscular dystrophy is multi-faceted, aiming to slow the progression of the disease, improve muscle function, and enhance the quality of life for patients. Treatments include corticosteroids, gene therapies, exon-skipping therapies, small molecules, and supportive measures like physical therapy, respiratory care, and cardiac management. While DMD remains a progressive disease with no cure, ongoing advancements in genetic therapies, small molecules, and supportive care offer hope for improving outcomes and potentially delaying or halting disease progression in the future. As research continues, new treatments are likely to provide even more targeted and effective ways to manage DMD.
Executive Summary
Market Dynamics: Drivers & Restraints
Gene therapy has been a breakthrough in DMD treatment by targeting the root cause of the disease, the absence of the dystrophin protein. This approach delivers genetic material to muscle cells, enabling the production of functional dystrophin and significantly slowing disease progression. The approval of gene therapies like Elevidys opens the door to new treatment options, attracting significant investment and research into the market, which drives growth and competition among pharmaceutical companies.
For instance, in June 2024, Sarepta Therapeutics, Inc. announced U.S. Food and Drug Administration (FDA) approval of an expansion to the labeled indication for ELEVIDYS (delandistrogene moxeparvovec-rokl) to include individuals with Duchenne muscular dystrophy (DMD) with a confirmed mutation in the DMD gene who are at least 4 years of age. Confirming the functional benefits, the FDA granted traditional approval for ambulatory patients. The FDA granted accelerated approval for non-ambulatory patients. Continued approval for non-ambulatory Duchenne patients may be contingent upon verification of clinical benefit in a confirmatory trial. ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene.
Additionally, in January 2025, Roche announced positive topline results from year two of the EMBARK trial, a global, randomised, double-blind phase III study of Elevidys (delandistrogene moxeparvovec), the first approved gene therapy for the treatment of individuals with Duchenne muscular dystrophy. Functional differences between individuals treated with Elevidys and those in the external control group increased between one and two years after dosing. Together, these results demonstrate consistent, sustained benefit in favour of Elevidys.
Exon-skipping therapies work by bypassing mutated sections of the dystrophin gene, allowing the production of a shortened but functional version of the dystrophin protein. This can slow disease progression and improve muscle function, particularly in patients with specific gene mutations. For instance, Exondys 51 (eteplirsen) and Vyondys 53 (golodirsen) are FDA-approved exon-skipping therapies that target specific mutations. These therapies have demonstrated positive clinical outcomes, such as improved motor function in younger patients. The approval of these therapies has increased awareness of DMD treatments and catalyzed further investment into research, fueling market expansion.
High drug costs for DMD treatment are hampering the market growth.
High drug costs for Duchenne muscular dystrophy treatment are a significant barrier to market growth. Although advancements in DMD therapies have been groundbreaking, the expensive nature of many treatments is limiting their accessibility and adoption, especially in low- and middle-income regions. This is affecting patients' ability to afford treatment, and thereby, limiting overall market expansion.
Gene therapies, such as Elevidys, have shown great promise in treating DMD by targeting the root cause of the disease—lack of dystrophin. However, the costs of gene therapies are extremely high. While the therapy offers long-term benefits, the upfront cost can make it financially unfeasible for many patients, particularly in regions with limited healthcare funding.
For instance, the FDA-approved gene therapy Elevidys carries a list price of approximately $3.2 million per patient, making it one of the most expensive treatments ever developed. Other DMD drugs, such as Exondys 51 and Vyondys 53, also come with annual costs exceeding $300,000, even though their efficacy may vary depending on the patient’s specific genetic mutation.
The high drug costs associated with advanced DMD treatments are hampering market growth by limiting patient access to these innovative therapies. Despite the breakthrough nature of treatments like gene therapies, exon-skipping drugs, and small molecules, their high costs create barriers to accessibility, particularly for patients in lower-income countries or those without sufficient insurance coverage. This results in inequitable treatment distribution, delayed adoption, and reduced market expansion, hindering the broader potential growth of the DMD treatment market.

Segment Analysis
The global Duchenne muscular dystrophy treatment market is segmented based on treatment type, route of administration, and region.
Treatment Type:
The gene therapies segment is expected to be fastest fastest-growing segment of the Duchenne muscular dystrophy treatment market.
Gene therapies are playing a transformative role in the treatment of Duchenne Muscular Dystrophy (DMD) by directly addressing the underlying genetic cause of the disease. These therapies aim to replace or repair the defective dystrophin gene responsible for muscle degeneration, offering the potential to not just manage symptoms but to correct the disease at a molecular level. Gene therapies are emerging as one of the most promising avenues in DMD treatment, and the FDA’s growing support for these therapies is significantly driving the market's growth.
Gene therapies like Elevidys (delandistrogene moxeparvovec), and pipeline products such as RGX-202, SGT-003, and GNT0004 are designed to introduce a functional version of the dystrophin gene into muscle cells, either by directly delivering the gene or by using advanced techniques like gene editing. These therapies help restore dystrophin production, which is critical for maintaining the integrity of muscle cells. Without dystrophin, muscle fibers are more prone to damage, leading to the progressive muscle weakness seen in DMD.
For instance, in June 2024, Sarepta Therapeutics, Inc. announced U.S. Food and Drug Administration (FDA) approval of an expansion to the labeled indication for ELEVIDYS (delandistrogene moxeparvovec-rokl) to include individuals with Duchenne muscular dystrophy (DMD) with a confirmed mutation in the DMD gene who are at least 4 years of age. ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene.
Moreover, RGX-202 by REGENXBIO is expected to be approved in 2027, and SGT-003 by Solid Biosciences is expected to be approved in 2026. These pipeline gene therapies are transforming the market in the coming years with better treatment options.
