FDA requests Sarepta Therapeutics to suspend distribution of Elevidys and places clinical trials on hold for multiple gene therapy products following 3 deaths
The U.S. Food and Drug Administration has placed Sarepta Therapeutics investigational gene therapy clinical trials for limb girdle muscular dystrophy on clinical hold following three deaths potentially related to these products and new safety concerns that the study participants are or would be exposed to an unreasonable and significant risk of illness or injury. The FDA has also revoked Sarepta’s platform technology designation.
The FDA leadership also met with Sarepta Therapeutics and requested it voluntarily stop all shipments of Elevidys today. The company refused to do so.
“Today, we’ve shown that this FDA takes swift action when patient safety is at risk.” said FDA Commissioner Marty Makary, M.D., M.P.H. “We believe in access to drugs for unmet medical needs but are not afraid to take immediate action when a serious safety signal emerges.”
The three deaths appear to have been a result of acute liver failure in individuals treated with Elevidys or investigational gene therapy using the same AAVrh74 serotype that is used in Elevidys. One of the fatalities occurred during a clinical trial conducted under an investigational new drug application for the treatment of Limb Girdle Muscular Dystrophy.
“Protecting patient safety is our highest priority, and the FDA will not allow products whose harms are greater than benefits. The FDA will halt any clinical trial of an investigational product if clinical trial participants would be exposed to an unreasonable and significant risk of illness or injury,” said Director of the FDA’s Center for Biologics Evaluation and Research Vinay Prasad, M.D., M.P.H.
Elevidys is an adeno-associated virus vector-based gene therapy using Sarepta Therapeutics’ AAVrh74 Platform Technology for the treatment of Duchenne muscular dystrophy (DMD).
