The Lancet Publishes HOPE-3 Data for Capricor Therapeutics’ Deramiocel in Duchenne Muscular Dystrophy
--Independent Peer Review Provides External Validation of the Trial's Design, Statistical Methodology and Findings--
--Randomized, Double-Blind, Placebo-Controlled HOPE-3 Phase 3 Trial (n=106) Met Primary Endpoint, with Deramiocel Slowing Upper Limb Function Decline by 54 Percent versus Placebo (PUL 2.0, p=0.03) and Showing Clinically Meaningful Cardiac Benefit--
--Deramiocel BLA Remains Under Active FDA Review, with PDUFA Target Action Date of August 22, 2026--
SAN DIEGO, July 29, 2026 (GLOBE NEWSWIRE) -- Capricor Therapeutics (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for rare diseases, today announced that The Lancet, one of the most selective and highly regarded peer-reviewed journals in medicine, has published results from the Company’s pivotal Phase 3 HOPE-3 clinical trial evaluating Deramiocel, its investigational cell therapy for the treatment of Duchenne muscular dystrophy (DMD). The manuscript underwent independent expert peer review, providing external validation of the trial’s design, statistical methodology and findings. The results are based on the Company’s prespecified Statistical Analysis Plan version 3.0 (SAP 3.0). The paper, titled “Deramiocel heart-derived cellular therapy in advanced Duchenne muscular dystrophy (HOPE-3): a phase 3, randomised, double-blind, placebo-controlled trial” can be accessed here.
“The HOPE-3 results are a landmark moment for the Duchenne community, demonstrating a significant benefit on skeletal muscle function alongside compelling data shown in cardiac function,” said Craig McDonald, M.D., Distinguished Professor of Physical Medicine & Rehabilitation and Pediatrics at UC Davis Health, National PI of the HOPE-2 and HOPE-3 trials and lead author of the publication. “A 54 percent slowing of upper limb disease progression (p=0.03) is a substantial, meaningful effect in a population where functional decline is typically relentless and irreversible. HOPE-3 is the first Phase 3 trial to demonstrate a significant benefit on function in a largely non-ambulatory DMD population, and the concurrent benefits in several cardiac measures lend biological support to a consistent treatment effect across skeletal and cardiac muscle. After many years of work, seeing a therapy deliver at this level has been a profound privilege.”
“The totality of evidence for Deramiocel is strong, with clinically meaningful benefits now published in The Lancet, one of medicine's most highly regarded journals," said Linda Marbán, Ph.D., CEO of Capricor. “The Lancet's rigorous, independent peer review process further validates these results. This is the same body of evidence that forms the foundation of our BLA and will be discussed at our Advisory Committee meeting. The publication reinforces our confidence in the strength and durability of these results in advance of Deramiocel's PDUFA target action date of August 22. We have continued to work with the FDA throughout its review, and we firmly believe this evidence supports approval. Deramiocel can change the course of this disease, and we are focused on our goal of bringing it to patients as the first approved cell therapy for Duchenne.”
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 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.
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 muscular dystrophies 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 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 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.
