Discovered and developed by Sarepta Therapeutics, Elevidys is a gene therapy that won accelerated approval in June 2023 and full approval in June 2024. Roche partnered with Sarepta in December 2019, paying $1.15 billion upfront in cash and stock for the right to launch and market Elevidys outside the U.S.

Sarepta Therapeutics has paused U.S. shipments of its gene therapy Elevidys after two teenagers with Duchenne muscular dystrophy died of liver failure. The suspension follows an FDA request and affects non-ambulatory patients.

Shipments will halt by close of business Tuesday evening, the company said. Sarepta had initially rejected the agency’s request, which was issued Friday.
