Sarepta's DMD gene therapy receives updated label with safety warnings

CAMBRIDGE, Mass. - Sarepta Therapeutics, Inc. (NASDAQ:SRPT) announced Friday that the prescribing information for ELEVIDYS, its gene therapy for Duchenne muscular dystrophy (DMD), has been updated with several key safety modifications. The company's stock, currently trading at $19.35, has experienced significant volatility, having fallen over 83% in the past year according to financial data.

The updated label now includes a boxed warning for the risk of acute serious liver injury and acute liver failure. Additionally, the non-ambulatory indication has been removed from the Indication and Usage section of the prescribing information. This regulatory setback comes as InvestingPro analysis shows the company is quickly burning through cash, with negative free cash flow of $451.54 million in the last twelve months.

The revised guidance for healthcare providers includes a modified pre- and post-infusion oral corticosteroids regimen and enhanced monitoring recommendations on a weekly basis for three months post-infusion. A new warning regarding increased susceptibility to serious infections due to immunosuppression has also been added.

"Completion of the safety labeling change for ELEVIDYS will ensure that families and healthcare professionals have clear information, supported by a Medication Guide, to help understand these updates and guide treatment decisions," said Louise Rodino-Klapac, president of research & development and technical operations at Sarepta.

According to the company, ELEVIDYS has been administered to over 1,100 patients globally in clinical and real-world settings. Sarepta stated it plans to quickly commence a study of an enhanced sirolimus immunosuppressive regimen to address the liver injury risks, with the goal of resuming dosing for non-ambulatory patients with FDA concurrence.

ELEVIDYS is currently indicated for ambulatory patients 4 years of age and older with DMD who have a confirmed mutation in the DMD gene. The single-dose, adeno-associated virus-based gene therapy is designed to address the underlying genetic cause of Duchenne muscular dystrophy.
