This Phase 3 trial tests a gene therapy called SRP-9001 for Duchenne muscular dystrophy (DMD), a severe muscle-wasting disease. It includes 148 males who can and cannot walk. Participants receive a one-time IV infusion of the therapy or a placebo, and are followed for about 128 w…

This study follows 500 people with Duchenne muscular dystrophy to see how well a gene therapy (ELEVIDYS) works compared to standard steroid treatment over time. Researchers will measure movement abilities, breathing, and safety, including liver problems. Participants must already…

This study tests a single dose of SRP-9003 gene therapy in 17 people with limb girdle muscular dystrophy 2E/R4, a genetic muscle-weakening disease. The goal is to restore a missing protein in muscle cells and improve muscle function. Both walkers and non-walkers can join, and the…

This Phase 3 trial tests whether higher doses of eteplirsen (Exondys 51) can safely improve muscle function in boys with Duchenne muscular dystrophy whose genetic mutation allows exon 51 skipping. About 160 ambulatory boys will receive one of three doses (30, 100, or 200 mg/kg) t…

This early-phase trial tests a single-dose gene therapy called SRP-9003 in 6 people with limb girdle muscular dystrophy type 2E/R4, a rare genetic muscle-weakening disease. The main goals are to check safety and see if the therapy can produce the missing beta-sarcoglycan protein …

This study follows about 400 people with Duchenne muscular dystrophy who have already received the gene therapy SRP-9001 in an earlier study. The goal is to monitor their safety and muscle function over time. No new treatment is given in this study.

This study follows 205 people with four types of limb-girdle muscular dystrophy (LGMD) to understand how the disease changes over time. Participants will have their muscle strength, movement, and breathing tested regularly for up to 5 years. No treatment is given; the goal is to …

This observational study will follow 300 people with Duchenne muscular dystrophy who are already taking exon-skipping therapies (eteplirsen, golodirsen, or casimersen) as part of their routine care. Researchers will collect data on movement, lung function, and heart function over…
