Duchenne muscular dystrophy
The FDA greenlit multiple new drugs this month and issued some notable label expansions including for Eli Lilly’s Kisunla. Meanwhile, the regulator turned away a cell therapy for Duchenne muscular dystrophy and a gene therapy for the rare disease Sanfilippo syndrome.
As analysts parsed news of Vinay Prasad’s ouster, worries over drug approval delays, cell and gene therapy impacts and more were top of mind.
Sarepta’s Elevidys is back on the market for ambulatory patients with Duchenne muscular dystrophy, Health Secretary Robert F. Kennedy Jr. reportedly plans to dissolve the U.S. Preventive Services Task Force and “fix” the vaccine injury compensation program, Merck, AstraZeneca and more report Q2 earnings, Novo names a new leader and Roche’s trontinemab impresses at AAIC25.
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.
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 faces serious FDA action after news broke of a third patient death, the FDA gets a new top drug regulator in George Tidmarsh, a handful of new drugs get turned away from the market and pharma companies continue to commit billions to reshoring manufacturing.
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.
