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.
Sarepta Therapeutics Inc. has set the wholesale acquisition cost of the first gene transfer therapy for ambulatory patients with Duchenne muscular dystrophy at $3.2 million, making it one of the most expensive gene therapies. The company said the gross-to-net price for Elevidys (delandistrogene moxeparvovec) will be in the mid-20% range, which, suggests Mizuho Group analyst Uy Ear, would put the price at about $2.4 million.
Sarepta Therapeutics Inc. is set to introduce the first gene transfer therapy for ambulatory patients diagnosed with Duchenne muscular dystrophy (DMD), after the U.S. FDA granted accelerated approval to SRP-9001 (delandistrogene moxeparvovec). Branded Elevidys, the therapy marks Sarepta’s fourth approved treatment for DMD and the first to offer patients a one-time treatment option.
Sarepta Therapeutics Inc.’s balloting March 12 from the U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee (OTAT) in favor of gene transfer therapy SRP-9001 (delandistrogene moxeparvovec) in Duchenne muscular dystrophy (DMD) had Wall Street mulling the odds for others in the space.
The debate over Sarepta Therapeutics Inc.’s gene transfer therapy, SRP-9001 (delandistrogene moxeparvovec), in Duchenne muscular dystrophy (DMD) proved as thorny as expected during a closely watched meeting of the U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee. Panelists voted on a single question: “Do the overall considerations of benefit and risk, taking into account the existing uncertainties, support accelerated approval of SRP-9001, using as a surrogate endpoint expression of Sarepta’s microdystrophin at week 12 after administration, for the treatment of ambulatory patients with DMD with a confirmed mutation in the DMD gene?” Balloting turned out 8 yes, 6 no.
How grave they might be remains unknown, but regulatory questions have surfaced in briefing documents related to the soon-to-happen panel meeting on Sarepta Therapeutics Inc.’s gene transfer therapy delandistrogene moxeparvovec in Duchenne muscular dystrophy (DMD). The U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee will meet May 12 to discuss the compound, also known as SRP-9001.
Sarepta Therapeutics Inc. CEO Doug Ingram said the U.S. FDA has promised to schedule “expeditiously” an advisory committee meeting on the BLA related to SRP-9001 (delandistrogene moxeparvovec) for Duchenne muscular dystrophy (DMD).
Sarepta Therapeutics Inc. said it plans to file a BLA for its gene therapy for Duchenne muscular dystrophy (DMD), SRP-9001, with the U.S. FDA, potentially setting up a decision in the first half of 2023 for the therapy developed in partnership with Switzerland’s Roche Holding AG. The Cambridge, Mass.-based biotech said the BLA will seek accelerated approval for the therapy, also known as delandistrogene moxeparvovec, for ambulant individuals with DMD.
