Sarepta Therapeutics, the maker of a gene therapy for Duchenne muscular dystrophy that is being temporarily shelved because of safety concerns, faces an “arduous and treacherous path” to try to get it back onto the market, a senior Food and Drug Administration official told STAT, suggesting the treatment’s license could be revoked. 

The official, who spoke to STAT on condition of anonymity, did not rule out the possibility that the therapy, Elevidys, could eventually be brought back on the market. But it would be difficult for Sarepta to prove that any new safety protocols could eliminate the risk of liver injuries — which have been tied to the deaths of two patients — the official added.

“How do you show something is safe when it’s already proven to be not safe?” the official said.
