SAN DIEGO, Sept. 09, 2025 (GLOBE NEWSWIRE) -- Capricor Therapeutics (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for rare diseases, today issued a statement regarding the U.S. Food and Drug Administration's (FDA) public posting of its Complete Response Letter (CRL) for the Biologics License Application (BLA) for Deramiocel, the Company's investigational cell therapy for the treatment of cardiomyopathy associated with Duchenne muscular dystrophy (DMD).
The Company was not notified in advance that the CRL would be posted, but acknowledges the FDA's decision to publish the letter, originally received in July 2025. However, the FDA did not release the comprehensive preliminary response that Capricor submitted shortly after receipt of the CRL. This written response provided clarifications to the Agency's feedback and outlined the Company's proposed plan to address the outstanding issues. To ensure transparency, Capricor will make its preliminary response available on the investor section of its website for patients, families, and other stakeholders to review.
"Transparency is vital in regulatory communications, especially when patients are waiting for therapies with the potential to alter the course of devastating diseases such as Duchenne muscular dystrophy," said Linda Marbán, Ph.D., Chief Executive Officer. "Our focus remains on working closely with the FDA to resolve the outstanding issues and to advance Deramiocel toward approval. While we respect the FDA's process, we believe it is important that the public has visibility into both the CRL and our detailed written response submitted to the Agency. We are now awaiting the official minutes from our recent Type A meeting with the FDA review team, expected to be issued later this quarter, which will help define the next steps in our regulatory pathway. Looking ahead, we expect topline HOPE-3 data in the fourth quarter of 2025, and our discussions with the FDA have centered on how these data will inform and support the timing of our BLA resubmission."
About Duchenne Muscular Dystrophy
Duchenne Muscular Dystrophy (DMD) is a severe, X-linked genetic disorder characterized by progressive muscle degeneration affecting the skeletal, respiratory, and cardiac muscles. It is caused by the absence of functional dystrophin, a key structural protein in muscle cells. DMD afflicts approximately 15,000 individuals in the United States and primarily impacts boys. Over time, deterioration of the heart muscle leads to cardiomyopathy and heart failure, which is the leading cause of death in DMD. There is no cure, and treatment options remain limited.
About Deramiocel
Deramiocel (CAP-1002) consists of allogeneic cardiosphere-derived cells (CDCs), a rare population of cardiac cells that have been shown in preclinical and clinical studies to exert potent immunomodulatory and anti-fibrotic actions in the preservation of cardiac and skeletal muscle function in dystrophiopathies such as DMD. CDCs act by secreting extracellular vesicles known as exosomes, which target macrophages and alter their expression profile to adopt a healing, rather than a pro-inflammatory phenotype. CDCs have been investigated in more than 250 peer-reviewed scientific publications and administered to over 250 human subjects across multiple clinical trials.
Deramiocel has received Orphan Drug Designation for the treatment of Duchenne Muscular Dystrophy (DMD) from both the U.S. FDA and the European Medicines Agency (EMA). In addition, it has been granted Regenerative Medicine Advanced Therapy (RMAT) designation in the U.S., Advanced Therapy Medicinal Product (ATMP) designation in Europe, and Rare Pediatric Disease Designation from the FDA, which may qualify Capricor for a Priority Review Voucher upon approval.
