Solid Biosciences Inc. has received FDA clearance of its IND application for SGT-003, the company’s next-generation gene therapy candidate for Duchenne muscular dystrophy (DMD). The planned first-in-human phase I/II trial will enroll pediatric patients with DMD to receive SGT-003 as a one-time intravenous infusion.

Failing to meet the primary endpoint in its confirmatory phase III Embark trial, Sarepta Therapeutics Inc.’s gene therapy, Elevidys (delandistrogene moxeparvovec), which received accelerated approval in June and was priced at $3.2 million, has one of three fates in its future, all of which are dependent on how the U.S. FDA perceives the data. Based on secondary endpoints showing statistical significance and a recent positive meeting with the agency, Sarepta could continue to market Elevidys under its current label for 4- and 5-year-old ambulatory Duchenne muscular dystrophy (DMD) patients; Sarepta is filing the postmarketing requirement needed to transition from accelerated to full approval.

While glucocorticoids are used as first-line therapy for Duchenne muscular dystrophy (DMD), these agents are associated with several adverse events, including accelerated bone loss and muscle atrophy. As a result, prolonged glucocorticoid treatment is one of the primary contributors to the high fracture rate in patients with DMD.

“We’re going to battle,” PTC Therapeutics Inc. CEO Matthew Klein said, responding to a surprise negative opinion from the EMA’s Committee for Medicinal Products for Human Use on converting the conditional marketing authorization to full status for Translarna (ataluren) in the treatment of nonsense mutation Duchenne muscular dystrophy. The opinion applies to the renewal of the existing conditional authorization, too.
