An FDA Panel Voted 9-3 Against Capricor on Cardiomyopathy and Never Voted on the Endpoint That Passed
- On 29 July 2026 the FDA’s Cellular, Tissue and Gene Therapies Advisory Committee voted 3 for, 9 against, 0 abstaining that available evidence did not support the effectiveness of Deramiocel for cardiomyopathy in patients with Duchenne muscular dystrophy. The vote is non-binding.
- Per Capricor, the voting question covered a narrower indication than the company had proposed and carried no vote on overall benefit-risk. In a separate discussion of upper limb function, the committee’s feedback was directionally supportive of the Phase 3 HOPE-3 evidence, including its primary endpoint, PUL 2.0.
- The PDUFA target action date is 22 August 2026, three weeks out. Advisory committee votes are recommendations, and the FDA can approve against them.
- Deramiocel is an allogeneic cardiosphere-derived cell therapy. DMD affects roughly 15,000 people in the United States, cardiomyopathy is the leading cause of death in the disease, and no cardiomyopathy treatment is currently approved for it. The programme holds Orphan Drug designation in the US and EU, plus RMAT, ATMP and Rare Pediatric Disease designation, the last of which may qualify Capricor for a priority review voucher on approval.
Clinical read
The ballot was the outcome. Capricor’s application is for cardiomyopathy, but HOPE-3’s primary endpoint was upper limb function, so the committee voted on the cardiac case and only discussed the muscle case, where its feedback ran supportive. A drug’s strongest dataset sitting off the ballot is not a procedural footnote, it is the whole result. Nine to three is what that construction produces. This is also the second round of the same argument. The FDA issued a Complete Response Letter in July 2025 over HOPE-2, and the dispute then, as now, was less about whether patients improved than about which statistical analysis plan governs the answer. Two trials, two fights over the analysis, one consistent agency position. The pattern is the signal, not any single p-value. The access half is harder. DMD cardiomyopathy is the leading cause of death in the disease and has no approved treatment, which is close to the strongest unmet-need argument available anywhere in rare disease, and it did not carry the vote. Unmet need is not currently substituting for statistical clarity at CBER. If the FDA approves anyway by 22 August, read the label before the headline: a narrow cardiac indication with a 9-3 negative panel behind it hands payers everything they need to restrict a repeat-infusion allogeneic cell therapy. And the Rare Pediatric Disease designation means a priority review voucher rides on approval, a balance-sheet event for a company this size regardless of how many patients are ever dosed.
