Sarepta’s DMD drug Elevidys to carry liver failure warning

17 November 2025

US genetic medicine company Sarepta Therapeutics (Nasdaq: SRPT) has announced an update to the prescribing information for Elevidys (delandistrogene moxeparvovec-rokl), its gene therapy for Duchenne muscular dystrophy (DMD).

Safety concerns for Elevidys came to a head this summer, leading to a pause of shipments in the USA and shaving billions off the drugmaker's valuation. 

Now, Sarepta reports, the product’s label will include several key updates, including a boxed warning for the risk of acute serious liver injury (ALI) and acute liver failure (ALF).
