SAN DIEGO, Aug. 13, 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 its financial results for the second quarter ended June 30, 2026, and provided a corporate update.

“Our priority is, and always has been, to get Deramiocel to the patients and families living with Duchenne who need it most,” said Linda Marbán, Ph.D., Chief Executive Officer of Capricor. “The Advisory Committee outcome was not the one we hoped for. The indication we requested in 2024 was the treatment of cardiomyopathy in DMD, and that is the question the Committee was asked to vote on, not the HOPE-3 primary endpoint. HOPE-3 was designed and powered to demonstrate efficacy in upper limb function; cardiac function was a key secondary endpoint, measured across all patients enrolled rather than only those with established cardiomyopathy. The full dataset has since been published in The Lancet following extensive and independent peer review, and we continue to believe there is a path to approval for Deramiocel.”

Dr. Marbán continued, “The most powerful part of the Advisory Committee was the open public hearing, where patients, families and clinicians described what this therapy has meant, or could mean, to them. That testimony is on the public record, and it is a reminder of how urgent the unmet need in Duchenne remains. We are continuing to work with the Agency on a path forward.”

Second Quarter 2026 and Recent Highlights

●

Deramiocel BLA Under FDA Review: Capricor is continuing to work with the FDA on the review of its BLA. The Company plans to provide a regulatory update on its conference call today and will provide further updates as they become available.

●

FDA Advisory Committee Outcome: On July 29, 2026, the Cellular, Tissue and Gene Therapies Advisory Committee voted 3 in favor and 9 against on whether available evidence provides substantial evidence of effectiveness of Deramiocel for the treatment of cardiomyopathy in patients with DMD. The Committee was not asked to vote on the HOPE-3 primary endpoint or on overall benefit-risk, and in a separate discussion of upper limb function its feedback was directionally supportive of the HOPE-3 clinical evidence. The recommendation is advisory and non-binding.

●

HOPE-3 Results Published in The Lancet: The full HOPE-3 Phase 3 dataset was published in The Lancet in July following extensive and independent peer review. Deramiocel demonstrated a statistically significant slowing of upper limb disease progression as measured by PUL 2.0 (p=0.029), with supportive results across additional functional and cardiac measures, which are characterized as nominally significant under the applicable hierarchical testing procedures. In connection with the peer review, Capricor identified an issue with the statistical model in the clinical study report and reverted to the statistical analysis plan in place prior to unblinding. The only endpoint affected was left ventricular ejection fraction, which yields (p=0.09) and a 1.8 percentage point treatment difference, compared to (p=0.04) and a 2.4 percentage point difference reported as topline data. The pre-specified cardiomyopathy subgroup was unchanged at (p=0.02), nothing else changed in the data or its analysis, and the HOPE-3 primary endpoint was unaffected.

●

FDA Bioresearch Monitoring Inspection: As part of the review process, the FDA conducted a BIMO inspection in July 2026 and issued a Form 483 citing one observation. The Company has submitted its responses and is currently awaiting feedback.

●

Commercial and Manufacturing Readiness: The Company's GMP manufacturing facility in San Diego is operational and positioned to support an initial commercial launch, if Deramiocel is approved. The second-floor expansion is targeted for full validation and FDA inspection in 2027, as planned. Michael Maurer joined as Chief

Commercial Officer, bringing direct DMD and rare disease experience, and has been judiciously building out the launch organization. Capricor is advancing commercial readiness at a slower pace pending regulatory clarity.

●

NS Pharma Dispute: The state court was scheduled to hear Capricor's motion for preliminary injunction on August 10, 2026, ahead of the PDUFA action date. Capricor withdrew the motion, without prejudice, having determined that resolving this contractual dispute in arbitration following the FDA's decision would give the parties a more complete regulatory record to work from. The Company estimates arbitration to begin this fall. Capricor's position on the underlying dispute has not changed: it continues to believe the pricing structure in the U.S. Distribution Agreement is fundamentally flawed in a way that would impede patient access, and continues to seek rescission.

●

Long-Term Safety and Efficacy Experience: Capricor has administered approximately 1,300 intravenous infusions of Deramiocel to over 200 patients with DMD across three separate clinical trials. More than 80 patients are enrolled in the Company's collective open-label extension studies, with some receiving continuous infusions for more than five years, and the long-term safety profile is consistent and well characterized.

●

Pipeline and Lifecycle Management: Capricor has initiated regulatory engagement in Europe and Japan for Deramiocel. Expansion into younger DMD patients and Becker muscular dystrophy remains a priority, with trial initiations stage-gated to the U.S. regulatory pathway for Deramiocel. Programs not directly related to Deramiocel, including the Company's exosome-based platform, are on hold pending further regulatory clarity.

Second Quarter 2026 Financial Results

●

Cash position: Cash, cash equivalents and marketable securities totaled approximately $237.9 million as of June 30, 2026, compared to approximately $318.1 million as of December 31, 2025.

●

Revenues: There was no revenue recognized for the first half of 2026 or 2025.

●

Costs and Expenses: Total operating expenses for the second quarter of 2026 were approximately $42.9 million, compared to approximately $27.7 million for the second quarter of 2025. Total operating expenses for the first half of 2026 were approximately $79.7 million, compared to approximately $52.7 million for the first half of 2025.

●

Net loss: The Company reported a net loss of approximately $40.7 million, or $0.70 per share, for the second quarter of 2026, compared to a net loss of approximately $25.9 million, or $0.57 per share, for the second quarter of 2025. The net loss for the first half of 2026 was approximately $74.7 million, or $1.29 per share, compared to a net loss of approximately $50.3 million, or $1.10 per share, for the first half of 2025.

●

Financial Outlook: The Company believes that, based on its current operating plan and financial resources, its available cash, cash equivalents and marketable securities are sufficient to fund its operating capital requirements for at least the next twelve months. The Company expects to provide additional guidance on its longer-term financial outlook following greater regulatory clarity, which will inform future strategic and capital allocation decisions. This outlook excludes any potential revenue from product sales, the potential monetization of a Priority Review Voucher, if received, or other non-operating sources of capital.

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.
