Capricor Gets FDA OK on Duchenne BLA Refiling

Share

Capricor Therapeutics says it has reached agreement with FDA on the design and role of its HOPE-3 trial as it works to resubmit its BLA for Deramiocel and its use in treating Duchenne muscular dystrophy (DMD). The update follows a Type A meeting with the agency, convened after it received an FDA complete response letter in July. According to Capricor, regulators agreed that HOPE-3 — a pivotal Phase 3 study now completed — can serve as the “additional study” requested in the CRL. The company expects to report topline data from the trial in mid-fourth quarter and include the results in its resubmission.

The company emphasized that prior to the CRL, most aspects of its BLA — including clinical data, manufacturing, and pre-licensing inspections — had undergone review without major issues. All chemistry, manufacturing and controls questions flagged in the letter have since been addressed, Capricor says.

Deramiocel comprises allogeneic cardiosphere-derived cells, a type of stromal cell that has shown promising immunomodulatory, antifibrotic, and regenerative effects in preclinical and clinical studies, according to the company. These cells work by secreting extracellular vesicles known as exosomes, which can reprogram macrophages to adopt a healing rather than a pro-inflammatory response.

The original BLA, which was granted a priority review in March, is based on data from the HOPE-2 trial, an open-label extension study, and natural history comparisons using FDA-funded datasets.

DMD is a progressive genetic disease that leads to severe muscle degeneration and heart failure. There is currently no cure, and treatment options remain limited. Cardiomyopathy is a leading cause of death in affected patients, according to the company.
