ELEVIDYS
delandistrogene moxeparvovec · INN
MoAAAVrh74-microdystrophin transfer

ELEVIDYS (delandistrogene moxeparvovec) is a one-time gene therapy for Duchenne muscular dystrophy — a fatal progressive muscle-wasting disease caused by dystrophin gene mutations — developed by Sarepta Therapeutics. The therapy uses a hollow AAVrh74 virus to deliver a shortened but functional microdystrophin gene into muscle cells throughout the body, enabling patients to produce a form of the missing structural protein. ELEVIDYS received accelerated FDA approval in 2023 as the first gene therapy for DMD; Sarepta is pursuing a label expansion to ambulatory patients aged 4 and older.

Indication
Rare Disease
Duchenne Muscular Dystrophy
MeSH · D020388

X-linked genetic disease causing progressive muscle weakness in boys. Median survival in late 20s with current care; gene therapy (ELEVIDYS) is the lead curative approach.
