The last couple of weeks has been particularly distressing for Duchenne muscular dystrophy patients and their families. The fate of Sarpeta’s gene therapy for the disease, called Elevidys, has been the center of a dizzying saga that seems to change by the minute.

Vinay Prasad has stepped down as head of the FDA’s biologics division just two months into the job, following growing backlash over how he handled Sarepta’s Elevidys, the only approved gene therapy for Duchenne muscular dystrophy.

Monday, the FDA said Sarepta may resume treating ambulatory DMD patients with Elevidys. The recommendation comes just 10 days after the agency requested that the company halt all shipments of the one-time treatment following reports of three deaths among patients who had received a Sarepta gene therapy, including two on Elevidys.
