This study tested a gene therapy called SRP-9003 for people with limb-girdle muscular dystrophy type 2E (LGMD2E), a rare genetic disease that causes muscle weakness. The treatment aimed to deliver a working gene to muscle cells to help them produce a missing protein. Only 6 peopl…

This study tested a gene therapy (delandistrogene moxeparvovec) combined with a drug called imlifidase to see if it could safely deliver the therapy to boys with Duchenne muscular dystrophy who had antibodies that might block the treatment. Only 5 participants were planned, but t…

This early study tested whether a blood-cleaning procedure called plasmapheresis could allow boys with Duchenne muscular dystrophy who have antibodies against the gene therapy carrier to still receive the treatment. Only 3 boys were enrolled before the study was stopped early. Th…

This was a very early (Phase 1) study testing a gene therapy called SRP-6004 for people with limb girdle muscular dystrophy type 2B/R2, a rare muscle-weakening disease. The goal was to see if a single IV infusion of the therapy is safe and can help the body produce a missing prot…

This early-stage trial tested a gene therapy called SRP-9004 in just 4 people with limb girdle muscular dystrophy type 2D/R3, a rare muscle-weakening disease. The main goal was to check safety, not effectiveness. The study was terminated early, so results are limited.
