Item 7.01

Regulation FD Disclosure.

On December 3, 2025, Capricor Therapeutics, Inc. (the “Company”) announced positive topline results from its pivotal Phase 3 HOPE-3 clinical trial. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference into this Item 7.01 of this Current Report on Form 8-K.

The information under Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into any of the Company’s filings under the Exchange Act, unless expressly set forth as being incorporated by reference into such filing.

Item 8.01

Other Events.

As disclosed above, the Company announced positive topline results from its pivotal Phase 3 HOPE-3 clinical trial. HOPE-3 is a randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating Deramiocel in boys and young men with Duchenne muscular dystrophy. The study randomized 106 participants across 20 leading U.S. clinical sites. Participants received intravenous Deramiocel at 150 million cells per infusion or placebo every three months for a 12-month period. The average age of participants was approximately 15 years and all were on a stable corticosteroid regimen throughout the study. Baseline demographics were well balanced between treatment arms, approximately 90 percent were receiving cardiac medications at baseline, and over 75 percent had diagnosed cardiomyopathy. Deramiocel maintained a favorable safety and tolerability profile consistent with prior clinical experience.

2 n reflects the number of patients in the ITT population with centrally reviewed and evaluable cardiac MRI LVEF assessments at 12 months.

3 Percent slowing is calculated as the treatment difference divided by the placebo change from baseline.

The Company expects that detailed HOPE-3 results will be submitted for presentation at a future scientific meeting and for publication in a peer-reviewed journal. Concurrently, the Company and its commercial partner, Nippon Shinyaku (U.S. subsidiary, NS Pharma, Inc.) are advancing launch readiness activities aimed to support timely patient access to Deramiocel, pending potential regulatory approval.
