Summary

This trial studies a gene therapy to treat Duchenne Muscular Dystrophy in boys. It's a 2-part, randomized, double-blind, placebo-controlled study lasting 128 weeks. Participants may get IV SRP-9001.

Who is the study for?
This trial is for non-ambulatory and ambulatory males with Duchenne Muscular Dystrophy (DMD), aged ≥8 to <18, who can perform motor assessment tests. They must be on a stable dose of corticosteroids and have specific genetic mutations in DMD. Those with high antibodies against the therapy vector or prior gene therapy are excluded.
What is being tested?
The study tests delandistrogene moxeparvovec, a gene transfer therapy for DMD. Participants will either receive this treatment or a placebo via IV over approximately 128 weeks in a randomized, double-blind setup where neither they nor the researchers know who gets what until after the study.
What are the potential side effects?
While not specified here, gene therapies like delandistrogene moxeparvovec may cause immune reactions, potential liver issues, and site-specific reactions at infusion points among other risks that would be monitored throughout the trial.
