On August 24, 2026, Capricor Therapeutics, Inc. (the “Company”) issued a press release announcing 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. The FDA has classified the submission as a major amendment, which extends the review period by three months. The amendment includes 24-month open-label extension data from Capricor’s pivotal Phase 3 HOPE-3 study, and additional analyses with a request for FDA’s review of the existing and new data in support of a refined proposed indication focused on upper limb function, the primary endpoint of HOPE-3.

A copy of the press release is filed herewith as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.
