Capricor Therapeutics Announces Orphan Drug Designation for Becker Muscular Dystrophy and Regulatory Progress for Duchenne Muscular Dystrophy Program

• U.S. FDA grants Orphan Drug Designation to Deramiocel for the treatment of Becker Muscular Dystrophy, broadening Capricor’s focus in neuromuscular diseases
• Capricor remains on track for the August 31, 2025, PDUFA date for Deramiocel in Duchenne Muscular Dystrophy following successful FDA Pre-License Inspection
  
  
  
  

SAN DIEGO, June 17, 2025 (GLOBE NEWSWIRE) -- (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for the treatment of rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted to Deramiocel, the company’s lead cell therapy candidate, for the potential treatment of Becker Muscular Dystrophy (BMD). This designation strengthens Capricor’s strategic position as it advances a fully integrated platform targeting the cardiac and skeletal complications of muscular dystrophy and expands the commercial potential of its lead asset.

Becker Muscular Dystrophy, like Duchenne Muscular Dystrophy (DMD), is a progressive X-linked neuromuscular disorder that results in significant skeletal and cardiac muscle deterioration over time. Deramiocel is being developed to address both aspects of disease pathology, including cardiomyopathy, a primary contributor to morbidity and mortality in patients with both BMD and DMD.

“The granting of Orphan Drug Designation for Becker Muscular Dystrophy is a significant milestone that expands the potential reach of Deramiocel and reinforces our vision to deliver impactful therapies across a broader spectrum of neuromuscular diseases,” said Linda Marbán, Ph.D., CEO of Capricor Therapeutics. “We believe Deramiocel holds promise for patients with Becker, particularly given the overlap in disease pathology with Duchenne. Deramiocel has demonstrated potential to treat the serious cardiac and skeletal muscle complications of Duchenne Muscular Dystrophy, and based on the overlap in disease pathology, may also offer benefit to patients with Becker Muscular Dystrophy.”

Dr. Marbán continued, “In addition, Capricor successfully completed its Pre-License Inspection, an important regulatory milestone for approval of its Biologics License Application (BLA) for DMD and we believe all review activities remain on track as we approach our PDUFA date. With key milestones aligning, we continue to prepare for the potential commercial launch of Deramiocel and the opportunity to deliver meaningful benefits to patients with Duchenne.”

Capricor’s Biologics License Application (BLA) for Deramiocel in DMD remains under priority review, with a PDUFA target action date of August 31, 2025.

About Duchenne and Becker 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 affects 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.

Becker Muscular Dystrophy (BMD) is a related dystrophinopathy caused by mutations in the same gene as DMD. It typically presents later in life with a slower disease progression and affects an estimated 5,000 individuals in the United States. Despite its milder course, many BMD patients develop serious cardiac complications, including cardiomyopathy, which can significantly affect both quality of life and longevity.

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. For Becker Muscular Dystrophy (BMD), Deramiocel has also received Orphan Drug Designation from the FDA.

About Capricor Therapeutics

Capricor Therapeutics (NASDAQ: CAPR) is a biotechnology company dedicated to advancing transformative cell and exosome-based therapeutics to redefine the treatment landscape for rare diseases. At the forefront of our innovation is our lead product candidate, Deramiocel, an allogeneic cardiac-derived cell therapy. Extensive preclinical and clinical studies have shown Deramiocel to exert potent immunomodulatory and anti-fibrotic actions in the preservation of cardiac and skeletal muscle function in muscular dystrophies such as DMD. Deramiocel is currently in late-stage development for the treatment of Duchenne Muscular Dystrophy. Capricor is also harnessing the power of its exosome technology, using its proprietary StealthX™ platform in preclinical development focused on the areas of vaccinology, targeted delivery of oligonucleotides, proteins and small molecule therapeutics to potentially treat and prevent a diverse array of diseases.
