Exhibit 99.1

Capricor Therapeutics Announces Extension of PDUFA Target Action Date as FDA Continues Review of Deramiocel BLA

– New PDUFA target action date of November 22, 2026 follows submission of additional Phase 3 HOPE-3 data and analyses supporting a refined proposed indication –

SAN DIEGO, Aug. 24, 2026 (GLOBE NEWSWIRE) — Capricor Therapeutics (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 extended the Prescription Drug User Fee Act (PDUFA) target action date for its Biologics License Application (BLA) for Deramiocel, an investigational cell therapy for Duchenne muscular dystrophy (DMD), from August 22, 2026 to November 22, 2026.

As part of its ongoing discussions with the FDA following the July 2026 Advisory Committee meeting, Capricor submitted an amendment to the BLA that includes 24-month open-label extension data from its pivotal Phase 3 HOPE-3 study and additional robustness analyses, with a request that the FDA review the existing and new data in support of a refined proposed indication focused on upper limb function, the primary endpoint of HOPE-3. The FDA's Center for Biologics Evaluation and Research (CBER) accepted the amendment for review, citing the significant unmet medical need in DMD. The FDA has classified the submission as a major amendment and extended the PDUFA target action date by three months to allow additional time to review the information.

“With an additional year of follow-up from HOPE-3, we now have one of the most extensive clinical datasets evaluating upper limb function in Duchenne,” said Linda Marbán, Ph.D., Chief Executive Officer of Capricor. “HOPE-3 met its primary endpoint, demonstrating a statistically significant benefit in upper limb function, and we believe the additional open-label data and further analyses included in the amendment strengthen the evidence supporting a refined proposed indication. We appreciate the FDA’s continued engagement and look forward to working constructively with the agency as it completes its review.”

Marbán continued, “The powerful testimony shared by patients, families and clinicians at the July Advisory Committee meeting underscored the importance of preserving upper limb function and the independence it provides for people living with Duchenne. In a progressive disease where function, once lost, cannot be recovered, we believe preservation of upper limb function has the potential to translate into meaningful differences in patients' independence and daily lives. That impact reinforces the urgency of our work and our commitment to bringing Deramiocel to the Duchenne community as soon as possible.”

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 immunomodulatory and anti-fibrotic actions in the preservation of skeletal and cardiac 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. For the treatment of DMD, Deramiocel holds Orphan Drug, RMAT and Rare Pediatric Disease designations in the

U.S., and Orphan Drug and ATMP designations in Europe. The Rare Pediatric Disease Designation may qualify Capricor for a Priority Review Voucher upon approval.
