SAN DIEGO, Feb. 29, 2024 (GLOBE NEWSWIRE) -- Capricor Therapeutics (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for the treatment and prevention of rare diseases, announced today its financial results for the fourth quarter and full year ended December 31, 2023 and provided a corporate update.

“2023 was a pivotal year for Capricor marked by major advances in our CAP-1002 cell therapy program for the treatment of Duchenne muscular dystrophy (DMD),” said Linda Marbán, Ph.D., Capricor’s chief executive officer. “Over the course of the year, we completed enrollment in Cohort A of our Phase 3, HOPE-3 pivotal trial, reported the positive outcome of our interim futility analysis, aligned with the U.S. Food and Drug Administration (FDA) on key deliverables necessary for the filing of a Biologics License Application (BLA), completed construction on our new San Diego manufacturing facility and began clinical dosing of Cohort B of the HOPE-3 trial from our San Diego facility. Each of these achievements are major milestones on our path towards potential approval of CAP-1002 for the treatment of DMD. While there are limited treatment options currently available for patients with DMD, we believe in the potential of CAP-1002’s ability to significantly slow down disease progression. Observed robust and consistent efficacy combined with a favorable safety/tolerability profile, positions CAP-1002 as a potential anchor therapy for patients. In 2024, we plan to meet with FDA to continue to discuss options for potential expedited approval pathways and Capricor is well-positioned to execute on several important milestones including reporting top-line data from our pivotal trial in the fourth quarter of 2024.”

Dr. Marbán, continued, “We continue to progress our proprietary StealthX™ exosome platform technology as part of our strategy to leverage exosomes for therapeutic development. We recently announced a collaboration for our exosome-based multivalent vaccine for the prevention of SARS-CoV-2 with the National Institute of Allergy and Infectious Diseases (NIAID) where they will conduct and fully fund a Phase 1 clinical trial, subject to regulatory approval. In addition, we are engaged in several discussions with potential partners focused on the development of an engineered exosome therapeutic, which would support our goal of building a pipeline of targeted exosome-based therapeutics.”

Fourth Quarter 2023 and Recent Operational Highlights

CAP-1002 Duchenne Muscular Dystrophy Program: CAP-1002 is an investigational cell therapy in Phase 3 development for the treatment of DMD. CAP-1002 aims to slow disease progression through immunomodulatory, anti-inflammatory, and anti-fibrotic actions, with the goal of potentially improving skeletal and cardiac muscle function in patients with DMD. HOPE-3, our Phase 3 study, is a multi-center, randomized, double-blind, placebo-controlled clinical trial comprised of two cohorts evaluating the safety and efficacy of CAP-1002 in participants with DMD and impaired skeletal muscle function. The trial is being conducted in the United States. Approximately 102 eligible study subjects will participate in this dual-cohort study (Cohort A and B). CAP-1002 for the treatment of DMD has received Orphan Drug Designation and RMAT (Regenerative Medicine Advanced Therapy Designation). In addition, if Capricor receives FDA marketing approval for CAP-1002 for the

treatment of DMD, Capricor would be eligible to receive a Priority Review Voucher (PRV) based on our previous receipt of a rare pediatric disease designation.

●

Enrollment has been completed for Cohort A in our Phase 3 trial which enrolled 61 subjects randomized to either CAP-1002 or placebo in a 1:1 ratio.

●

Reported a positive outcome from the interim futility analysis for Cohort A which triggered the first milestone payment of $10.0 million under our U.S. Distribution and Commercialization Agreement with Nippon Shinyaku. There is an additional $90.0 million in potential milestone payments up to the time of approval which are triggered upon certain regulatory-based achievements. Following potential approval, there is an additional $605.0 million in potential milestones payments which may be payable to Capricor based on various sales-based targets being met. Further, Capricor will receive a meaningful mid-range double-digit revenue share of product revenue under the terms of this Agreement.

●

Next steps for Cohort A: plan to report top-line data in the fourth quarter of 2024.

●

Enrollment is underway for Cohort B designed to enroll approximately 44 subjects randomized to either CAP-1002 or placebo in a 1:1 ratio.

●

Next steps for Cohort B: expect to complete enrollment in the second quarter of 2024.

●

Announced the scale-up to expand manufacturing capacity of CAP-1002 to our new San Diego facility, intended for commercial use, subject to regulatory approval. This facility was designed to be a versatile and cost-effective way to bring CAP-1002 to market efficiently and it is expected that our enhanced manufacturing capacity will increase our supply capabilities and improve our margins on ultimate product sales, if any. We are currently producing CAP-1002 doses at our San Diego facility for use in Cohort B.

●

Announced a positive outcome from a Type-B meeting held with FDA in the third quarter of 2023. In the meeting, the FDA affirmed alignment on the current HOPE-3 clinical trial design comprised of two cohorts and our plan to submit a BLA supported by results from Cohort A which uses product manufactured from our Los Angeles manufacturing facility.

●

We plan to meet with FDA in the first quarter of 2024 to continue discussing our pathway to BLA. In the upcoming Type-B meeting, we intend to discuss our further CMC plans for commercial launch, if approved, with an aim to expedite the approval pathway to our BLA filing. Our ultimate goal is to transition to our San Diego manufacturing facility for commercial manufacturing as quickly as possible.

●

Hosted a webinar in conjunction with Parent Project Muscular Dystrophy (PPMD) where key updates on our DMD program were outlined.

●

Presented a late-breaking poster at the 28^th International Annual Congress of the World Muscle Society (WMS). Highlights from the poster included data from the HOPE-2 OLE trial measured by the Performance of the Upper Limb (PUL 2.0) showing a delta change=4.9 points, p=0.021 after 24-months of treatment, compared with the placebo patient group.

Exosome Program: Exosomes are membrane-bound extracellular vesicles which are secreted by most cells and contain characteristic lipids, proteins and nucleic acids such as mRNA and microRNAs. Exosomes act as messengers to regulate the functions of neighboring or distant cells and have been shown to regulate functions such as cell survival, proliferation, inflammation and tissue regeneration. We are developing our exosome technology, using our proprietary StealthX™ platform which is focused on the areas of vaccinology, targeted delivery of oligonucleotides, proteins and small molecule therapeutics to potentially treat and prevent a diverse array of diseases.

●

Announced that our proprietary StealthX™ exosome-based multivalent vaccine (StealthX™ vaccine) for the prevention of SARS-CoV-2 was selected to be part of Project NextGen, an initiative by the U.S. Department of Health and Human Services to advance a pipeline of new, innovative vaccines providing broader and more durable protection for COVID-19. As part of Project NextGen, NIAID, part of the National Institutes of Health, will conduct and fund a Phase 1 clinical trial with our StealthX™ vaccine, subject to regulatory approval. Under the terms of the collaboration, Capricor will supply the investigational product and NIAID's Division of Microbiology and Infectious Diseases (DMID) will oversee the trial.

●

Next steps for this project: NIAID plans to initiate the Phase 1 clinical trial in late 2024, subject to regulatory approval. If NIAID finds that our StealthX™ vaccine meets its criteria for safety and efficacy, they may consider our program for a funded Phase 2.

●

Currently, in collaboration with an undisclosed pharmaceutical company, we are also investigating the therapeutic application of our StealthX™ exosome platform.

●

Presented a late-breaking poster at the WMS on the application of our StealthX™ exosome platform for the delivery of antisense oligonucleotides (ASO). Highlights from the poster included data showing the presence of exosomes loaded with a labeled ASO in the lower limbs of mice 24 hours post-intravenous (IV) injection. Notably, the exosomes carrying the muscle-targeting moiety were not detected in any other tissues except for the expected clearance pathways (kidney and liver) with a single dose.
