Capricor’s Duchenne Cell Therapy BLA Resubmitted

Share

FDA has accepted for review a Capricor Therapeutics BLA resubmission for its experimental cell therapy deramiocel, intended to treat heart complications in patients with Duchenne muscular dystrophy. FDA classified the filing as a Class 2 resubmission and set a new user fee review action target date of 8/22.

The BLA resubmission follows Capricor’s submission of additional clinical data from its HOPE-3 trial after FDA issued a complete response letter on the original BLA 7/2025. The company says the agency has not identified any new potential review issues since accepting the updated filing.

Capricor CEO Linda Marbán said in a statement that results from the HOPE-3 study and other clinical evidence support the therapy’s potential as a first-in-class treatment for Duchenne muscular dystrophy affecting both skeletal and cardiac muscle.

Deramiocel is described as an investigational, first-in-class allogeneic cell therapy designed to preserve cardiac and skeletal muscle function in patients with Duchenne muscular dystrophy, a rare and fatal genetic disease marked by progressive muscle degeneration. The therapy consists of cardiosphere-derived cells that act primarily through exosomes, which are believed to modulate immune responses and reduce fibrosis, the company says.
