The FDA’s recent decisions on Replimune and Capricor have thrown a spotlight on the agency’s evolving regulatory stance. Replimune clinched a crucial approval for its melanoma drug, Tudriqev, after a decisive 10-3 vote from an advisory committee. This is a stark turnaround from prior rejections based on the FDA’s skepticism of single-arm trials. Capricors is at the center of this development.
Replimune’s success story is not just about the drug itself but also a reflection of the FDA’s willingness to reconsider its rigid stance on trial designs. In contrast, Capricor’s Duchenne therapy met with resistance. Despite hitting key trial endpoints, the FDA’s advisory committee voted against it, citing statistical inconsistencies.
Capricor’s CEO, Linda Marbán, has been vocal in her criticism, accusing the FDA of dismissing critical data due to outdated analysis plans. Yet, there’s a glimmer of hope as the FDA hinted at a possible extension of Capricor’s action date, suggesting a window for reassessment.
These cases underscore the FDA’s attempt to restore its credibility post-leadership turmoil, balancing between flexibility and stringent data scrutiny. Replimune’s approval serves as a beacon of possibility, while Capricor’s ongoing struggle highlights the unpredictable nature of FDA reviews.
The clearest new takeaway from the latest reporting is that Replimune got its melanoma drug approved on August 6, 2026, but Capricor’s Duchenne therapy is still mired in a statistical and procedural fight that has become the test case for whether the FDA is actually becoming more predictable again. The FDA said on August 6, 2026 that it granted accelerated approval to vusolimogene oderparepvec-wtpg, or Tudriqev, in combination with nivolumab for adults with unresectable advanced cutaneous melanoma whose disease progressed after a PD-1-blocking regimen.
BioSpace reported that the advisory committee voted 10-3 in favor, a notable show of support after the FDA had previously objected to the single-arm trial underpinning the application. In Replimune’s earlier rejection, the agency said the data were “insufficient to conclude substantial evidence of effectiveness” and specifically signaled it “would not recommend” approval based on a single-arm study, even after the company had resubmitted analyses on mechanism of action and outcomes relative to prior immunotherapy.
The official target action date had been August 22, 2026, after the company’s February 20 resubmission was accepted as a Class 2 review, so any extension would be a meaningful procedural reprieve rather than a final rejection. On Capricor’s second-quarter earnings call last week, Marbán said the FDA had signaled it was “willing to review this amendment and upon receipt to extend the PDUFA action date accordingly,” suggesting the agency may still be open to an alternative path despite the 9-3 negative vote.
That came just one week after the Cellular, Tissue, and Gene Therapies Advisory Committee met on July 30, 2026, and after what BioSpace described as a “perilous regulatory road” involving two prior rejections. At the July 29, 2026 advisory committee meeting, deramiocel was voted down 9-3, even though Capricor says its Phase III HOPE-3 trial hit both the primary and secondary endpoints.
embodied the divide between statistical rigor and patient desperation; and FDA reviewers effectively redrew the stakes by insisting that data flexibility has limits. Cassidy, one of the yes votes for Capricor, accused the agency of using “technicalities and procedural errors” to dismiss data “out of hand,” while another yes voter, Debra Dunn, admitted, “I’m a mom.
