Gene therapy
The swift FDA action removes an overhang from Sarepta and allows Elevidys to return to the market without another safety study, as had been feared, Jefferies analysts said Monday.
Brazilian authorities said the death was unlikely to have been caused by Elevidys and was instead more in line with severe infection exacerbated by immunosuppression.
The European Union’s health regulatory agency did not endorse approving Elevidys for ambulatory patients with Duchenne muscular dystrophy.
The strategic reprioritization comes after the company hit two major hurdles in the past year, including a clinical hold for an investigational gene therapy and an FDA rejection for its lead asset.
CBER is unanimously against Elevdiys’ return to the market without additional evidence, according to media reports citing an anonymous senior FDA official. Given Elevidys’ full approval, however, experts told BioSpace this path would set up a length legal battle between the regulator and Sarepta Therapeutics.

The voluntary pauses follow two patient deaths associated with the Duchenne muscular dystrophy gene therapy.
Sarepta Therapeutics’ stock has dropped precipitously as questions swirl around the safety of its gene therapies. Meanwhile, the Duchenne patient community fears losing access to Elevidys while the regulator considers more drastic action.
After initially refusing to suspend Elevidys distribution after two deaths, Sarepta has now given in to the FDA’s request, noting the need to maintain a good working relationship with the regulator.
In light of recent patient deaths, the FDA has also revoked its platform designation for Sarepta’s AAVrh74 technology. The designation, granted last month, was the first of its kind to be announced publicly.
