The Food and Drug Administration won’t sign off on Sarepta Therapeutics Inc. bringing its controversial gene therapy back to the market until the company can persuade US regulators that it won’t cause more deaths,

Roche Holding AG said on Tuesday it has paused shipments of muscular disorder gene therapy Elevidys in some countries outside the U.S., echoing a similar decision by U.S. partner Sarepta Therapeutics .

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.
