On Wednesday, U.S. pharmaceutical giant Sarepta Therapeutics announced that it will be laying off 500 employees and will issue a severe warning on the label of its gene therapy drug Elevidys for muscle diseases. This decision comes after the tragic deaths of two patients following the administration of the drug. The company aims to reduce annual costs by approximately $400 million through this restructuring effort. Furthermore, at the request of the Food and Drug Administration (FDA), Sarepta has added a warning about the risk of liver failure to the Elevidys label. Following this announcement, Sarepta's share price surged by over 35% after market close.
