Duchenne Muscular Dystrophy Drugs Market - Global Forecast 2026-2032

The Duchenne Muscular Dystrophy Drugs Market size was estimated at USD 1.85 billion in 2025 and expected to reach USD 2.02 billion in 2026, at a CAGR of 9.31% to reach USD 3.46 billion by 2032.

Duchenne muscular dystrophy (DMD) is a devastating genetic disorder characterized by the progressive degeneration of skeletal and cardiac muscle fibers, leading to loss of ambulation and premature mortality. Affecting approximately one in every 5,000 live male births globally, DMD manifests in early childhood, typically around age three, with rapidly worsening muscle weakness that compromises respiratory and cardiac function over time. Despite decades of research, there remains no definitive cure, and therapeutic interventions have historically focused on slowing disease progression and managing symptoms to preserve patient quality of life and function.

Over the past decade, the treatment paradigm for DMD has shifted dramatically with the introduction of novel approved therapies targeting the underlying mechanisms of pathology. Corticosteroid therapy, long the standard of care for its anti-inflammatory and immune-modulating properties, received its first U.S. approval with deflazacort (Emflaza) in February 2017, offering an alternative to prednisone with a potentially improved safety profile for patients aged five years and older. Building on this foundation, exon-skipping antisense oligonucleotides such as eteplirsen (Exondys 51) achieved accelerated approval in September 2016 by exploiting patient-specific genetic mutations to restore dystrophin production, laying the groundwork for subsequent agents like viltolarsen (Viltepso) and casimersen, which expanded exon-skipping to additional mutation subtypes.

More recently, gene therapy has emerged at the forefront of DMD innovation, promising long-term dystrophin expression through viral vector–mediated delivery. Sarepta Therapeutics’ Elevidys became the first U.S.-approved gene therapy for DMD but has since faced significant safety concerns and regulatory holds following reports of acute liver toxicity and patient fatalities in clinical trials. These developments underscore the promise and perils of next-generation DMD treatments and highlight the need for rigorous safety monitoring, long-term outcome studies, and adaptive regulatory frameworks to support sustainable patient access. This executive summary provides an in-depth exploration of these therapeutic advances, regulatory shifts, market segments, and strategic considerations shaping the DMD drug landscape today.

The DMD treatment landscape has undergone transformative shifts owing to breakthroughs in molecular targeting and evolving regulatory expectations. Exon-skipping therapies, which leverage antisense oligonucleotides to bypass deleterious gene mutations, have matured from proof-of-concept in small cohorts to becoming mainstays in clinical practice. The accelerated approval of eteplirsen, golodirsen and casimersen has validated dystrophin restoration as a regulatory endpoint, spurring investment in next-generation oligonucleotides and combination regimens aimed at enhancing muscle function and delaying progression beyond ambulatory status.

Concurrently, gene therapy has redefined expectations for durable clinical benefit, with adeno-associated virus (AAV) vectors engineered to deliver functional dystrophin genes systemically. Initial successes with Elevidys demonstrated proof of principle for single‐dose interventions, but post‐marketing safety signals involving acute liver injury and rare fatalities have prompted the FDA to pause shipments, necessitating refined vector designs, dose optimization, and robust long‐term surveillance strategies. Moreover, innovations beyond viral vectors, including nonviral gene transfer techniques and genome editing platforms, are gaining traction in preclinical studies, foreshadowing a future where precision therapies may offer curative potential without immunogenicity concerns.

Underpinning these scientific advances is a more adaptive and collaborative regulatory environment that increasingly emphasizes patient‐centered outcomes, real‐world evidence generation, and post‐approval safety commitments. Regulatory agencies are partnering with patient advocacy groups and manufacturers to co-define success criteria, streamline clinical trial designs, and facilitate accelerated pathways, which together are catalyzing the translation of novel modalities and reshaping the DMD treatment paradigm into an era of precision medicine.

Evaluating how sweeping 2025 U.S. tariff policies are influencing drug costs supply chains and strategic sourcing decisions in pharma

In early 2025, comprehensive U.S. trade measures introduced a 10% tariff on all imported goods, including active pharmaceutical ingredients (APIs) and finished drug products, as part of a broader effort to stimulate domestic manufacturing. This blanket tariff has amplified production expenses across the pharmaceutical value chain, particularly for generics and biologic intermediates, driving firms to reassess sourcing strategies and supply chain configurations to mitigate cost pressures and maintain competitive pricing.

More targeted duties have further exacerbated trade tensions, with tariffs ranging up to 245% on Chinese APIs and 20% on Indian counterparts, reflecting national security considerations and geopolitical fragmentation. Such extreme levies threaten to disrupt the supply of critical drug components and elevate domestic production costs, compelling companies to explore onshoring options or diversify supplier portfolios. Parallel analyses by Ernst & Young estimate that a 25% tariff on finished pharmaceutical imports could add nearly $51 billion annually to U.S. drug expenditures and increase prices by up to 12.9% if fully passed through to consumers, underscoring the stakes for industry stakeholders and policymakers in balancing supply resilience with affordability.

In response, leading biopharma companies are intensifying efforts to localize API production, forge strategic partnerships for integrated manufacturing, and advocate for selective tariff exemptions for critical healthcare inputs. These adaptive strategies aim to preserve patient access to innovative treatments like those for DMD while navigating an increasingly volatile global trade environment.
