Sarepta would need to conduct new analyses to validate the safety of Elevidys—which has had U.S. shipments paused by the company over a mounting string of controversies—to the FDA, Endpoints News and Bloomberg separately reported Thursday, citing an unnamed senior FDA official.

The U.S. Food and Drug Administration (FDA) is investigating the death of an eight-year-old boy who received Sarepta Therapeutics (NASDAQ: SRPT) gene therapy, Elevidys, for Duchenne muscular dystrophy (DMD).

While Sarepta has now consented to the FDA’s request to stop selling Elevidys, the company’s brief standoff with the agency could still carry major consequences for the Duchenne community.
