Capricor Therapeutics Gains New Hope for Duchenne Muscular Dystrophy Treatment

Capricor Therapeutics has received a promising update from the U.S. Food and Drug Administration (FDA) regarding its experimental cell therapy for Duchenne muscular dystrophy (DMD). The company is now preparing to resubmit its application for deramiocel, a potential treatment for Duchenne-related cardiomyopathy, following a constructive meeting with FDA officials.

FDA Reconsideration and Hope-3 Trial

In a surprising turn of events, the FDA has indicated its willingness to reconsider Capricor's application for deramiocel with new data from the completed Hope-3 clinical trial. This development comes just two months after the agency's initial rejection of the therapy in July, which had raised questions about the research supporting its effectiveness.

Capricor CEO Linda Marbán expressed optimism about the outcome of the FDA meeting, stating, "This is a giant win for us." The company now anticipates submitting the results from the Hope-3 trial, which are expected to be available in mid-fourth quarter, without the need for an entirely new application process.

Hope-3 Trial Details and Potential Implications

The Hope-3 trial, involving 105 patients, compares deramiocel to a placebo administered every three months. The primary endpoint of the study focuses on changes in upper limb function, with secondary endpoints including improvements in cardiac muscle function and structure.

If the trial results prove positive, Capricor believes it could support a label for deramiocel that addresses both cardiac and skeletal muscle function in DMD patients. This comprehensive approach could potentially position deramiocel as the first treatment specifically targeting heart-related complications of Duchenne muscular dystrophy.

Regulatory Landscape and Market Response

The FDA's decision to reconsider deramiocel comes amid changes in the agency's leadership, particularly in the oversight of gene and cell therapies. Despite these shifts, Capricor has found a path forward for its therapy, with Marbán noting, "I feel very, very positive about our interactions with the agency right now."

The news has had a positive impact on Capricor's stock, which rose approximately 9% in early trading following the announcement. This uptick provides a welcome relief for the company, whose shares had previously plummeted after the FDA's July rejection and had lost more than half their value over the preceding six months.
