This exponential growth is largely driven by the increasing incidence of DMD, breakthrough gene and exon-skipping therapies, and strong regulatory support within the region.

Market Drivers & Growth Catalysts

• Surge in FDA Approvals and Regulatory Incentives
  The FDA’s accelerated approval pathways and orphan-drug designations have fast-tracked DMD drug availability. Notable approvals include Elevidys (expanded indication in 2024), Duvyzat (givinostat), and Agamree (vamorolone), significantly broadening the treatment landscape.

• Expansion of Exon-Skipping and Molecular Therapies
  Exon-skipping oligonucleotides—such as eteplirsen, golodirsen, viltolarsen, and casimersen—continue to dominate, targeting specific genetic mutations. In 2024, these molecular-based therapies accounted for roughly 50% of market share, driven by their mutation-specific efficacy.

• Breakthrough Gene Therapies Launched
  The approval of gene therapy Elevidys and emerging platforms from firms like Roche, RegenxBio, and Pfizer paint a promising picture. These one-time treatments target the dystrophin gene, offering transformative potential for long-term muscle function restoration.

• Increasing R&D Funding and Biotech Investments
  Research activity is soaring, with multiple late-stage trials, including Sarepta’s exon-skipping expansion trials and Avidity’s RNA-based candidates. The executive shift towards genetic medicine is attracting substantial investment across North America.

• Advocate-Driven Market Momentum
  Patient advocacy groups, newborn screening programs, and supportive healthcare policies in the U.S. and Canada are improving early diagnosis, public awareness, and policy frameworks, fueling market expansion.

Regional Insights

North America commands approximately 40%–45% of the global DMD therapeutics market, fueled by high healthcare investment, specialized care delivery, and strong diagnostic infrastructure. The U.S. remains the dominant hub, while Canada emerges rapidly due to a favorable research and reimbursement environment.

Latest Developments & Trends

• April 2025: The FDA approved givinostat (Duvyzat) for anyone aged six or older, marking the first non-steroidal oral DMD treatment.

• October 2023: Vamorolone (Agamree) became the first FDA-approved selective steroid for DMD.

• Expanded Elevidys Label: In 2024, the therapy’s eligible patient base increased dramatically—from 7% to roughly 80–90% of U.S. patients—opening access to ambulatory and non-ambulatory children.

• RNA Innovations: Avidity Biosciences’ del-zota candidate boosted dystrophin production in early trials, signaling next-gen RNA therapeutic potential.

Challenges & Market Restraints

• High Therapy Costs: Gene therapies like Elevidys have list prices around USD 3.2 million. Exon-skipping treatments can exceed USD 300,000 annually.

• Mutation-Dependent Access: Molecular therapies benefit only specific patient subsets, potentially excluding 50–60% of the DMD population.

• Manufacturing and Supply Constraints: Large-scale production of gene therapies remains technically complex.

• Data Gaps in Long-Term Outcomes: Many novel treatments lack real-world data on long-term safety and durability.

Strategic Outlook & Recommendations

• Optimize reimbursement structures to ensure access to high-cost therapies.

• Expand genetic screening to improve early intervention and therapy eligibility.

• Invest in manufacturing scale-up and supply chain resilience.

• Support registries and longitudinal studies for long-term safety tracking.

• Advance combination approaches that include gene, exon-skipping, and anti-inflammatory strategies.
