Sarepta Therapeutics Inc. said another patient has died from acute liver failure after receiving one of its gene therapies, putting additional pressure on the biotech company after the recent deaths of two teenage boys.

Second patient death from liver failure after Sarepta's Elevidys gene therapy triggers FDA investigation. Stock crashes 41% as company halts non-ambulatory patient treatments.

Drugmaker Sarepta Therapeutics says it won't comply with a request from U.S. regulators to halt all shipments of its gene therapy.
