Capricor Therapeutics Challenges FDA Rejection of DMD Cardiomyopathy Drug

What's Happening?

Capricor Therapeutics is preparing to resubmit its application for deramiocel, a cell therapy for cardiomyopathy associated with Duchenne muscular dystrophy (DMD), after receiving a complete response letter from the FDA. The rejection followed the abrupt cancellation of an advisory committee meeting, allegedly influenced by internal disputes at the FDA. Capricor's CEO, Linda Marbán, expressed surprise at the rejection, given previous positive interactions with the FDA. The company plans to address the concerns raised in the CRL and resubmit the application, potentially using data from ongoing trials as supportive evidence.

Why It's Important?

The FDA's rejection of deramiocel highlights the complexities and challenges in the regulatory approval process for novel therapies, especially in the field of rare diseases. Capricor's efforts to overturn the decision are significant for patients with DMD, as cardiomyopathy is a leading cause of mortality in this population. The company's ability to navigate the regulatory landscape and provide compelling clinical data will be crucial in advancing treatment options for DMD. The situation also underscores the importance of clear communication and alignment between biotech companies and regulatory bodies.

What's Next?

Capricor plans to resubmit the Biologics License Application (BLA) for deramiocel, incorporating data from the Phase III HOPE-3 trial expected later this year. The company aims to demonstrate the drug's efficacy in stabilizing cardiomyopathy in DMD patients. Capricor is also adjusting the trial protocol to focus on left ventricular ejection fraction as the primary efficacy endpoint. The outcome of these efforts will determine the future availability of deramiocel as a treatment option for DMD cardiomyopathy.
