Sarepta to Present Long-Term Data on Gene Therapy, Exon-Skipping Treatments

  • Sarepta Therapeutics will present data at the Muscular Dystrophy Association (MDA) Clinical & Scientific Congress, March 8-11, 2026.
  • Key presentations include a late-breaking oral presentation on delandistrogene moxeparvovec (gene therapy) with up to three years of follow-up data.
  • Data will also be presented on golodirsen and casimersen (exon-skipping treatments) and a real-world analysis of survival in patients treated with Sarepta’s medicines.
  • A pooled safety analysis of delandistrogene moxeparvovec clinical trials will cover up to 7.5 years of patient follow-up.

Sarepta’s continued focus on long-term data generation underscores the increasing importance of demonstrating durable efficacy and safety in rare disease gene therapies. The company’s leadership position in this niche market, valued at approximately $3.5 billion, is predicated on maintaining a robust pipeline and generating compelling clinical evidence. The presentation at MDA represents a key opportunity to reinforce Sarepta’s position and address investor concerns regarding the long-term value proposition of its treatments.

Clinical Validation
The long-term safety and efficacy data on delandistrogene moxeparvovec will be critical in solidifying its commercial viability and justifying its premium pricing, especially given the scrutiny of gene therapy cost-effectiveness.
Real-World Evidence
The real-world survival analysis will provide a more nuanced view of treatment impact beyond controlled clinical trials, potentially influencing payer coverage decisions and patient access.
Regulatory Risk
The FDA’s assessment of the pooled safety data, particularly regarding adverse events within the first 60 days post-infusion, could impact future approval pathways for Sarepta’s gene therapy programs.
