Capricor Therapeutics (NASDAQ: CAPR) HOPE-3 data in Lancet as FDA review nears
Rhea-AI Filing Summary
Capricor Therapeutics announced that The Lancet has published the final one-year results from its Phase 3 HOPE-3 trial of Deramiocel in Duchenne muscular dystrophy, based on Statistical Analysis Plan 3.0. The randomized, double-blind, placebo-controlled study (n=106) met its primary endpoint, with Deramiocel slowing upper limb function decline by 54 percent versus placebo on PUL 2.0 (p=0.03). Deramiocel’s Biologics License Application for DMD remains under active FDA review, with a PDUFA target action date of August 22, 2026.
In dialogue with FDA and peer reviewers, Capricor updated the statistical model for left ventricular ejection fraction, yielding p=0.09 and a 1.8 percentage point treatment difference, versus p=0.04 and 2.4 points previously, while a pre-specified cardiomyopathy subgroup remained nominally significant at p=0.02. An FDA Bioresearch Monitoring inspection of HOPE-3 operations resulted in a Form FDA 483 citing one observation tied to procedures, documentation, vendor oversight and audit timeliness; the company stated it does not believe this affects HOPE-3 data integrity and plans a complete, timely response.
Positive
- HOPE-3 Phase 3 trial met its primary endpoint, with Deramiocel slowing upper limb function decline by 54 percent versus placebo on PUL 2.0 (p=0.03), and the full one-year results now published in The Lancet after independent peer review.
- Deramiocel’s Biologics License Application remains under active FDA review, with a defined PDUFA target action date of August 22, 2026 for the Duchenne muscular dystrophy indication.
Negative
- Updated analysis of left ventricular ejection fraction under a revised statistical model now yields p=0.09 and a 1.8 percentage point treatment difference, versus the previously reported p=0.04 and 2.4 points, weakening statistical support for this key secondary endpoint.
- FDA Bioresearch Monitoring inspection led to a Form FDA 483 citing one observation related to standard operating procedures, documentation practices, vendor oversight and audit report timeliness in the HOPE-3 trial, requiring a formal response from the company.

Phase 3 Peer-Review Publication; Update to Statistical Model for LVEF
On July 29, 2026, Capricor Therapeutics, Inc. ("Capricor" or the "Company") issued a press release announcing the publication in The Lancet of the final one-year results from its HOPE-3, Phase 3 clinical trial evaluating Deramiocel, its investigational cell therapy for the treatment of Duchenne muscular dystrophy ("DMD"). The manuscript underwent independent peer review, providing external validation of the trial's statistical methodology and findings. The results, which have now been published, are based on the Company’s prespecified Statistical Analysis Plan version 3.0 ("SAP 3.0").
As part of its ongoing dialogue with the FDA regarding the HOPE-3 data, and in connection with the peer review process with The Lancet, the Company identified an update to the statistical model used in its analysis of left ventricular ejection fraction ("LVEF"), the key secondary endpoint of the study. Under the revised model, LVEF yields a p=0.09 (1.8 percentage point treatment difference), compared to p=0.04 previously reported (2.4 percentage point treatment difference). In the pre-specified cardiomyopathy subgroup, the result is nominally significant at p=0.02 (2.8 percentage point treatment difference). The other additional type-1 error-controlled endpoints will be characterized as nominally significant under applicable hierarchical testing procedures. The primary efficacy endpoint result and all other trial data remain unchanged.
A copy of the press release has been filed as Exhibit 99.1 hereto and is incorporated herein by reference.
Bioresearch Monitoring (BIMO) Inspection
On July 4, 2026, the Company was notified by the FDA of a Bioresearch Monitoring (BIMO) inspection of the Company’s clinical operations related to its Biologics License Application for Deramiocel for the treatment of DMD. The inspection commenced on July 6, 2026 and concluded on July 20, 2026.
At the conclusion of the inspection, the FDA issued a Form FDA 483, Notice of Inspectional Observations, citing one observation relating primarily to the Company's standard operating procedures, documentation practices, vendor oversight, and audit report timeliness in connection with the conduct of the HOPE-3 clinical trial. The Company does not believe the observation affects the integrity or reliability of the HOPE-3 data. The Company is preparing its formal response and intends to respond completely in a timely manner.

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
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.
