Sarepta Therapeutics, Inc.
NEWS
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.
The rollercoaster week for Sarepta Therapeutics continued, with shares of the embattled gene therapy-turned-siRNA biotech down 37% Friday afternoon as media outlets reported FDA plans to request a stop to all shipments of the Duchenne muscular dystrophy therapy Elevidys following a third patient death linked to the underlying platform.
The patient, who was being treated with an investigational gene therapy for limb-girdle muscular dystrophy, died of acute liver failure, the same complication responsible for the deaths of two boys taking Sarepta’s Duchenne muscular dystrophy treatment Elevidys.
Sarepta Therapeutics appears to have right-sized itself after laying off over a third of its staff, announcing a significant pipeline shift and adding a black box warning to its Duchenne muscular dystrophy gene therapy Elevidys.
Around 3,500 FDA employees received termination emails; FDA Commissioner Marty Makary suggests lowering industry user fees and tying review times to drug prices; the regulator opens its trove of complete response letters in the name of transparency; and two companies receive rejections for rare disease therapies.
A journey through the FDA’s newly released complete response letters gave glimpses into the journeys to market for Eli Lilly’s Alzheimer’s antibody Kisunla, Sarepta’s DMD gene therapy Vyondys 53 and Gilead’s HIV drug Sunlenca.
Another patient has died from acute liver failure after receiving Sarepta’s gene therapy for DMD ; After a quiet start to the year, M&A is back with one deal for a gene editing biotech reinvigorating that sector; and RFK Jr. installs a suite of new vaccine board members who share his skeptical views on vaccines.
Sarepta’s shares crashed 41% in premarket trading Monday morning to $21.01 after the biotech reported a second death from acute liver failure, a known side effect of adeno-associated virus-based gene therapies.
Since Elevidys’ accelerated approval in 2023, experts have been clamoring for more data, particularly in older and non-ambulatory children. New results, presented Friday, show mobility improvements in 8- to 9-year-old patients after one year of follow-up.
