The adeno-associated virus (AAV) vector-based gene therapy delandistrogene moxeparvovec-rokl (Elevidys – Sarepta) received accelerated approval from the FDA in 2023 for treatment of ambulatory children 4-5 years old with Duchenne muscular dystrophy (DMD) who have a confirmed mutation in the DMD gene. It has now received full approval for use in ambulatory patients ≥4 years old and accelerated approval for use in nonambulatory patients with DMD.

Delandistrogene moxeparvovec-rokl (Elevidys – Sarepta), an adeno-associated virus (AAV) vector-based gene therapy, has received accelerated approval from the FDA for treatment of ambulatory children 4-5 years old with Duchenne muscular dystrophy (DMD) who have a confirmed mutation in the dystrophin gene. It is the first gene therapy to be approved in the US for treatment of DMD. Accelerated approval was based on expression of microdystrophin in skeletal muscle, a surrogate endpoint.
