As disclosed above, the Company announced positive topline results from its pivotal Phase 3 HOPE-3 clinical trial. HOPE-3 is a randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating Deramiocel in boys and young men with Duchenne muscular dystrophy. The study randomized 106 participants across 20 leading U.S. clinical sites. Participants received intravenous Deramiocel at 150 million cells per infusion or placebo every three months for a 12-month period. The average age of participants was approximately 15 years and all were on a stable corticosteroid regimen throughout the study. Baseline demographics were well balanced between treatment arms, approximately 90 percent were receiving cardiac medications at baseline, and over 75 percent had diagnosed cardiomyopathy. Deramiocel maintained a favorable safety and tolerability profile consistent with prior clinical experience.

**SAN DIEGO,** Dec. 3, 2025 (GLOBE NEWSWIRE) -- <u>Capricor Therapeutics</u> (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for the treatment of rare diseases, today announced positive topline results from its pivotal Phase 3 HOPE-3 trial evaluating Deramiocel, the Company's investigational cell therapy for the treatment of Duchenne muscular dystrophy (DMD).

"HOPE-3 delivered strong and definitive evidence that Deramiocel can meaningfully improve the course of Duchenne muscular dystrophy, demonstrating statistically significant improvements in both skeletal and cardiac function," said Linda Marbán, Ph.D., Chief Executive Officer of Capricor. "These results reinforce the durable benefits seen in HOPE-2 and its open-label extension, which has continued for over 48 months, and highlight the strength, consistency and reproducibility of Deramiocel's clinical profile after more than a decade of rigorous clinical development. We believe these pivotal study results, in addition to the evidence from the HOPE-2 and HOPE-2 OLE studies, position us to address the clinical issues in the Complete Response Letter received earlier this year, consistent with prior FDA guidance that HOPE-3 results should be sufficient to support regulatory approval."

HOPE-3 is a randomized, double-blind, placebo-controlled, Phase 3 clinical trial evaluating Deramiocel in boys and young men with Duchenne muscular dystrophy. The study randomized 106 participants across 20 leading U.S. clinical sites. Participants received intravenous Deramiocel at 150 million cells per infusion or placebo every three months for a 12-month period. The average age of participants was approximately 15 years, and all were on a stable corticosteroid regimen throughout the study. Baseline demographics were well balanced between treatment arms, approximately 90 percent were receiving cardiac medications at baseline, and over 75 percent had a clinical diagnosis of cardiomyopathy. Deramiocel maintained a favorable safety and tolerability profile consistent with prior clinical experience.

Rehabilitation and Pediatrics at UC Davis Health, and National PI of the HOPE-3 trial. "A nearly 54 percent slowing of skeletal muscle disease progression is extraordinary in Duchenne and directly linked to maintaining independence and quality of life in the most severely affected patients with greatest unmet need. The preservation of function reflected in PUL v2.0 translates into real, practical benefits for boys and young men living with this disease, and the effect of Deramiocel on cardiomyopathy will potentially translate to improved long-term survival. The HOPE-3 study is the first-ever Phase 3 trial in a largely non-ambulatory population with DMD to successfully meet its primary endpoint and to support the development of an innovative therapy over many years with this level of impact has been a profound privilege."

"The cardiac findings from HOPE-3 represent a significant advance in the management of Duchenne muscular dystrophy cardiomyopathy," said Jonathan Soslow, M.D., MSCI, Professor of Pediatrics (Cardiology) at Vanderbilt University Medical Center. "Cardiomyopathy is the leading cause of mortality in Duchenne, and stabilizing cardiac function has remained a major unmet need. The statistically and clinically significant preservation of left ventricular ejection fraction in patients treated with Deramiocel observed in HOPE-3 underscores the potential of Deramiocel to address one of the most critical aspects of the disease."

Dr. Marbán continued, "For families living with Duchenne who are looking for therapies that preserve functional ability, protect the heart and maintain independence, today's results provide real momentum and meaningful progress, offering renewed confidence as we work to advance Deramiocel toward potential regulatory approval."

We expect that detailed HOPE-3 results will be submitted for presentation at a future scientific meeting and for publication in a peer-reviewed journal.

***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 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.

***About the HOPE-3 Phase 3 Trial***

HOPE-3 is a Phase 3, multi-center, randomized, double-blind, placebo-controlled clinical trial consisting of two cohorts evaluating the safety and efficacy of Deramiocel in participants with DMD. Non-ambulatory and ambulatory boys who meet eligibility criteria are randomly assigned to receive either Deramiocel or placebo every 3 months for a total of four doses during the first 12 months of the trial. A total of 106 eligible subjects were randomized in the dual-cohort trial. For more information, please visit ClinicalTrials.gov (<u>NCT05126758</u>).

***About Capricor Therapeutics***
