On July 11, 2025, Capricor Therapeutics, Inc. (the “Company” or “Capricor”) issued a press release announcing that it has received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding its Biologics License Application (BLA) for Deramiocel, the Company’s lead cell therapy candidate for the treatment of cardiomyopathy associated with Duchenne muscular dystrophy (DMD).

In the CRL, the FDA stated that it had completed its review of the application but was unable to approve the BLA in its current form, citing the BLA does not meet the statutory requirement for substantial evidence of effectiveness and the need for additional clinical data. The CRL also referenced certain outstanding items in the Chemistry, Manufacturing, and Controls (CMC) section of the application, most of which the Company believes it has addressed in communications to the FDA in response to prior comments before receipt of the letter, but which were not reviewed by the FDA due to the timing of the CRL issuance. The FDA confirmed that it will restart the review clock upon resubmission. In addition, the agency offered the Company the opportunity to request a Type A meeting to discuss the path forward. Capricor plans to engage further with the FDA to determine the appropriate next steps and intends to resubmit its BLA to include data from the ongoing Phase 3 HOPE-3 trial in the third quarter of 2025 in support of its pursuit of an indication for the treatment of cardiomyopathy associated with Duchenne muscular dystrophy.

​

A copy of the press release has been filed as Exhibit 99.1 hereto and is incorporated herein by reference.

The information under Item 7.01 of this Current Report on Form 8-K, 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.
