Capricor Therapeutics Announces Positive 4-Year Data from HOPE-2 Open-Label Extension Study of Deramiocel in Duchenne Muscular Dystrophy
Four-year data show preservation of cardiac function, including LVEF Skeletal muscle disease progression continues to slow with extended treatment (PUL v2.0) Deramiocel's long-term safety profile remains favorable Results presented at PPMD's 2025 Annual Conference SAN DIEGO, June 20, 2025 (GLOBE NEWSWIRE) -- Capricor Therapeutics (NASDAQ: CAPR), a biotechnology company developing transformative cell and exosome-based therapeutics for rare diseases, today announced positive four-year safety and efficacy results from its ongoing HOPE-2 Open-Label Extension (OLE) study of Deramiocel, the Company's lead cell therapy candidate for Duchenne Muscular Dystrophy (DMD). The data will be featured in the session titled 'Therapies that Slow Progression' at the Parent Project Muscular Dystrophy (PPMD) 2025 Annual Conference, taking place June 21, 2025, in Las Vegas, Nevada. After four years of continuous treatment, Deramiocel-treated patients showed a median change of -0.5 points compared to baseline. Further, a subgroup analysis of patients with baseline LVEF >45% showed an even greater clinical benefit, supporting early intervention with Deramiocel to potentially preserve cardiac function. Additionally, treatment continued to slow skeletal muscle disease progression, as measured by Performance of the Upper Limb (PUL v2.0), with patients experiencing a smaller average decline in the fourth year (0.6 points) compared to the first year (1.8 points). Together, these findings suggest that extended treatment with Deramiocel may help attenuate the progression of DMD over time. Deramiocel continues to maintain a favorable safety profile throughout the study. 'Cardiomyopathy remains one of the leading causes of mortality in Duchenne and addressing this aspect of the disease is critical to improving outcomes,' said Pat Furlong, Founding President and CEO of PPMD. 'The long-term data from the HOPE-2 OLE study are encouraging, particularly in demonstrating cardiac stabilization over four years. Deramiocel represents an important therapeutic approach and we support continued progress through the regulatory pathway to ensure that treatments targeting both heart and muscle function are available to our community as quickly as possible.' 'These four-year data reinforce the strength and durability of Deramiocel's clinical benefit and favorable safety profile across both cardiac and skeletal muscle function,' said Linda Marbán, Ph.D., CEO of Capricor Therapeutics. 'With our BLA under priority review and several key regulatory steps now completed, we are executing with focus and urgency as we move toward potential approval. Our continued dialogue with the FDA remains on track with no evidence of any delays. We thank the patients, families, and clinicians who have been instrumental in advancing this program.' The PPMD Annual Conference is the largest international event focused on advancing research, clinical trials, and standards of care for Duchenne and Becker muscular dystrophies. Capricor's presentation will be available following the conference in the publications section of the Company's was a randomized, double-blind, placebo-controlled Phase 2 study of Deramiocel in boys and young men with Duchenne Muscular Dystrophy (DMD). Patients received intravenous infusions of either Deramiocel (150 million cells) or placebo every three months. The results were published in The Lancet. Following study completion, all patients entered a treatment gap phase for approximately 392 days (range: 239–567). Eligible patients then enrolled in the HOPE-2 OLE study, receiving Deramiocel every three months. The OLE study previously met its primary endpoint at one year with statistically significant improvement on the PUL v2.0 (p=0.02). Now in its fifth year, the HOPE-2 OLE study remains ongoing, with participants continuing to be monitored for safety, cardiac function, and upper limb Muscular Dystrophy (DMD) is a severe, X-linked genetic disorder characterized by progressive muscle degeneration affecting the skeletal, respiratory, and cardiac muscles. It is caused by the absence of functional dystrophin, a key structural protein in muscle cells. DMD affects approximately 15,000 individuals in the United States and primarily impacts boys. Over time, deterioration of the heart muscle leads to cardiomyopathy and heart failure, which is the leading cause of death in DMD.

Dyne Therapeutics Announces New Long-Term Clinical Data from Phase 1/2 DELIVER Trial of DYNE-251 in Duchenne Muscular Dystrophy Demonstrating Unprecedented and Sustained Functional Improvement Through 18 Months
- Continued favorable safety profile for DYNE-251 - - DELIVER Registrational Expansion Cohort is fully enrolled; data from this cohort planned for late 2025 - - Potential for Biologics License Application submission for U.S. accelerated approval in early 2026 - WALTHAM, Mass., March 16, 2025 (GLOBE NEWSWIRE) -- Dyne Therapeutics, Inc. (Nasdaq: DYN), a clinical-stage company focused on advancing life-transforming therapeutics for people living with genetically driven neuromuscular diseases, today announced new long-term clinical data from its ongoing Phase 1/2 DELIVER trial of DYNE-251 demonstrating unprecedented and sustained functional improvement at the selected registrational dose of 20 mg/kg Q4W (approximate PMO dose). The DELIVER trial is evaluating DYNE-251 in individuals with Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping, and updated results from the trial are being presented this week at the 2025 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference. 'With Dyne-251, we have the opportunity to deliver a durable and redosable therapy demonstrating clinically meaningful and sustained functional improvement in DMD. The consistency of these new data across multiple endpoints and timepoints underscores the potential of DYNE-251 to meaningfully address the significant unmet need in Duchenne despite available therapies,' said John Cox, president and chief executive officer of Dyne. 'We are rapidly advancing DYNE-251 toward a readout later this year with the potential to submit for U.S. accelerated approval in early 2026 based on a well-established regulatory pathway leveraging dystrophin expression as a surrogate endpoint. If approved, we believe there is an opportunity for rapid adoption by physicians and currently treated patients, as well as those naïve to therapy.' 'I am very encouraged by these new, long-term data for DYNE-251 in the exon 51 skip amenable population and the promise of sustained functional improvement which has continued to elude the DMD community,' said Pat Furlong, founder and president of Parent Project Muscular Dystrophy. 'The investment and innovation in DMD are delivering, and this is a prime example of how the accelerated approval pathway may swiftly enable a new generation of therapies that address unmet and urgent medical needs.' "The amount of expression of near-full length dystrophin induced by DYNE-251 has not been previously seen with exon 51 skipping agents and is associated with evidence for clinical efficacy,' said Kevin Flanigan M.D., Director, Center for Gene Therapy, Abigail Wexner Research Institute at Nationwide Children's Hospital. 'I look forward to the opportunity to present new functional data and updated safety data at the 2025 MDA Clinical & Scientific Conference.' This updated assessment of the DELIVER trial evaluating DYNE-251 includes new functional data out to 12 months from 6 patients enrolled in the 20 mg/kg Q4W cohort, and 18-month functional data from 6 patients in the 10 mg/kg Q4W cohort (these participants began transitioning to the 20 mg/kg Q4W regimen after month 6). In addition, updated safety data as of February 7, 2025, continue to demonstrate a favorable safety profile for DYNE-251. Key findings from the DELIVER Phase 1/2 trial presentation include: Function: Meaningful and sustained improvements from baseline in multiple functional endpoints were observed in both the 20 mg/kg (selected registrational dose) and 10 mg/kg1 DYNE-251 Q4W cohorts, through 12 and 18 months, respectively. Functional assessments included Stride Velocity 95th Centile (SV95C), North Star Ambulatory Assessment (NSAA), 10-Meter Walk/Run Time (10-MWR), and Time to Rise from Floor. Starting at the 6-month timepoint, the SV95C change from baseline observed in both the 10 mg/kg and 20 mg/kg cohorts of DELIVER exceeded the published proposed minimal clinically important difference (MCID). SV95C is a digital objective outcome measure of ambulatory performance in patients' normal daily environment and is accepted as a primary endpoint for DMD clinical trials in Europe. Dystrophin expression: As previously reported, DYNE-251 demonstrated unprecedented near-full length dystrophin expression as measured by Western blot for patients with DMD who are amenable to exon 51 skipping. At the 6-month time point, patients treated with 20 mg/kg of DYNE-251 Q4W had a mean absolute dystrophin expression of 8.72% of normal (adjusted for muscle content). Dyne has confirmed that the U.S. Food and Drug Administration precedent for using dystrophin as a surrogate biomarker for accelerated approval remains available. Safety and tolerability: DYNE-251 has demonstrated a favorable safety profile based on 54 participants enrolled in the DELIVER trial. Since the prior update provided as of November 21, 2024, the safety profile remains unchanged, and no new treatment-related serious adverse events have been observed.2 970 doses of study drug have been administered to date over a period of 77.1 patient-years of follow-up with some patients followed for up to ~2.5 years. 546 doses of study drug at the 20 mg/kg dose level have been administered to date.3 Key Milestones for the DELIVER Trial Dyne continues to pursue expedited approval pathways globally for DYNE-251 in patients with DMD who are amenable to exon 51 skipping. Dyne has fully enrolled the Registrational Expansion Cohort of 32 patients as part of the DELIVER trial. Data from this cohort are planned for late 2025. Dyne anticipates a potential Biologics License Application (BLA) submission for U.S. accelerated approval in early 2026. Dyne Presentations at the 2025 MDA Clinical & Scientific ConferenceThe new assessment of the DELIVER trial is being presented in an oral presentation 'Safety and Efficacy from the Ongoing Phase 1/2 DELIVER Trial of DYNE-251 in Males with DMD Mutations Amenable to Exon 51 Skipping' on Wednesday, March 19, at 8:30-8:45 a.m. CT by Kevin Flanigan, M.D., Director, Center for Gene Therapy, Abigail Wexner Research Institute of Nationwide Children's Hospital in Columbus, Ohio and Principal Investigator for the DELIVER Trial. A poster with the same title will be available starting at 6:00 p.m. CT Sunday, March 16, 2025, through Tuesday, March 18, 2025, in the conference exhibit hall. Both the oral presentation and poster are now available in the Scientific Publications & Presentations section of Dyne's website, along with several other posters and presentations including an encore presentation of the most recent positive results for DYNE-101 from the Phase 1/2 ACHIEVE trial in myotonic dystrophy type 1 (DM1). About the DELIVER Trial DELIVER is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of DYNE-251 in patients with Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. The multiple ascending dose (MAD) portion of the study resulted in the selection of a registrational dose and regimen of 20 mg/kg every four weeks. A registrational expansion cohort to support potential regulatory submissions for expediated approvals, including accelerated approval in the U.S., is fully enrolled. The primary endpoint for this cohort is the change from baseline in dystrophin protein levels as measured by Western blot. For more information on the DELIVER trial, visit (NCT05524883) and (2023-510351-31-00). About DYNE-251 DYNE-251 is an investigational therapeutic being evaluated in the Phase 1/2 global DELIVER clinical trial for people living with DMD who are amenable to exon 51 skipping. DYNE-251 consists of a phosphorodiamidate morpholino oligomer (PMO) conjugated to a fragment antibody (Fab) that binds to the transferrin receptor 1 (TfR1) which is highly expressed on muscle. It is designed to enable targeted muscle tissue delivery and promote exon skipping in the nucleus, allowing muscle cells to create internally shortened, near full-length dystrophin protein, with the goal of stopping or reversing disease progression. DYNE-251 has been granted fast track, orphan drug and rare pediatric disease designations by the U.S. Food and Drug Administration for the treatment of DMD mutations amenable to exon 51 skipping. In addition to DYNE-251, Dyne is building a global DMD franchise and has preclinical programs targeting other exons, including 53, 45 and 44. About Duchenne Muscular Dystrophy (DMD) DMD is a rare disease caused by mutations in the gene that encodes for dystrophin, a protein critical for the normal function of muscle cells. These mutations, the majority of which are deletions, result in the lack of dystrophin protein and progressive loss of muscle function. DMD occurs primarily in males and affects an estimated 12,000 to 15,000 individuals in the U.S. and 25,000 in Europe. Loss of strength and function typically first appears in pre-school age boys and worsens as they age. As the disease progresses, the severity of damage to skeletal and cardiac muscle often results in patients experiencing total loss of ambulation by their early teenage years and includes worsening cardiac and respiratory symptoms and loss of upper body function by the later teens. There is no cure for DMD, and currently approved therapies provide limited benefit. About Dyne Therapeutics Dyne Therapeutics is discovering and advancing innovative life-transforming therapeutics for people living with genetically driven neuromuscular diseases. Leveraging the modularity of its FORCE™ platform, Dyne is developing targeted therapeutics that deliver to muscle and the central nervous system (CNS). Dyne has a broad pipeline for neuromuscular diseases, including clinical programs for myotonic dystrophy type 1 (DM1) and Duchenne muscular dystrophy (DMD) and preclinical programs for facioscapulohumeral muscular dystrophy (FSHD) and Pompe disease.

This updated assessment of the DELIVER trial evaluating DYNE-251 includes new functional data out to 12 months from 6 patients enrolled in the 20 mg/kg Q4W cohort, and 18-month functional data from 6 patients in the 10 mg/kg Q4W cohort (these participants began transitioning to the 20 mg/kg Q4W regimen after month 6). In addition, updated safety data as of February 7, 2025, continue to demonstrate a favorable safety profile for DYNE-251. Key findings from the DELIVER Phase 1/2 trial presentation include: Function: Meaningful and sustained improvements from baseline in multiple functional endpoints were observed in both the 20 mg/kg (selected registrational dose) and 10 mg/kg1 DYNE-251 Q4W cohorts, through 12 and 18 months, respectively. Functional assessments included Stride Velocity 95th Centile (SV95C), North Star Ambulatory Assessment (NSAA), 10-Meter Walk/Run Time (10-MWR), and Time to Rise from Floor. Starting at the 6-month timepoint, the SV95C change from baseline observed in both the 10 mg/kg and 20 mg/kg cohorts of DELIVER exceeded the published proposed minimal clinically important difference (MCID). SV95C is a digital objective outcome measure of ambulatory performance in patients' normal daily environment and is accepted as a primary endpoint for DMD clinical trials in Europe. Dystrophin expression: As previously reported, DYNE-251 demonstrated unprecedented near-full length dystrophin expression as measured by Western blot for patients with DMD who are amenable to exon 51 skipping. At the 6-month time point, patients treated with 20 mg/kg of DYNE-251 Q4W had a mean absolute dystrophin expression of 8.72% of normal (adjusted for muscle content). Dyne has confirmed that the U.S. Food and Drug Administration precedent for using dystrophin as a surrogate biomarker for accelerated approval remains available. Safety and tolerability: DYNE-251 has demonstrated a favorable safety profile based on 54 participants enrolled in the DELIVER trial. Since the prior update provided as of November 21, 2024, the safety profile remains unchanged, and no new treatment-related serious adverse events have been observed.2 970 doses of study drug have been administered to date over a period of 77.1 patient-years of follow-up with some patients followed for up to ~2.5 years. 546 doses of study drug at the 20 mg/kg dose level have been administered to date.3 Key Milestones for the DELIVER Trial Dyne continues to pursue expedited approval pathways globally for DYNE-251 in patients with DMD who are amenable to exon 51 skipping. Dyne has fully enrolled the Registrational Expansion Cohort of 32 patients as part of the DELIVER trial. Data from this cohort are planned for late 2025. Dyne anticipates a potential Biologics License Application (BLA) submission for U.S. accelerated approval in early 2026. Dyne Presentations at the 2025 MDA Clinical & Scientific ConferenceThe new assessment of the DELIVER trial is being presented in an oral presentation 'Safety and Efficacy from the Ongoing Phase 1/2 DELIVER Trial of DYNE-251 in Males with DMD Mutations Amenable to Exon 51 Skipping' on Wednesday, March 19, at 8:30-8:45 a.m. CT by Kevin Flanigan, M.D., Director, Center for Gene Therapy, Abigail Wexner Research Institute of Nationwide Children's Hospital in Columbus, Ohio and Principal Investigator for the DELIVER Trial. A poster with the same title will be available starting at 6:00 p.m. CT Sunday, March 16, 2025, through Tuesday, March 18, 2025, in the conference exhibit hall. Both the oral presentation and poster are now available in the Scientific Publications & Presentations section of Dyne's website, along with several other posters and presentations including an encore presentation of the most recent positive results for DYNE-101 from the Phase 1/2 ACHIEVE trial in myotonic dystrophy type 1 (DM1). About the DELIVER Trial DELIVER is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of DYNE-251 in patients with Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. The multiple ascending dose (MAD) portion of the study resulted in the selection of a registrational dose and regimen of 20 mg/kg every four weeks. A registrational expansion cohort to support potential regulatory submissions for expediated approvals, including accelerated approval in the U.S., is fully enrolled. The primary endpoint for this cohort is the change from baseline in dystrophin protein levels as measured by Western blot.

About DYNE-251 DYNE-251 is an investigational therapeutic being evaluated in the Phase 1/2 global DELIVER clinical trial for people living with DMD who are amenable to exon 51 skipping. DYNE-251 consists of a phosphorodiamidate morpholino oligomer (PMO) conjugated to a fragment antibody (Fab) that binds to the transferrin receptor 1 (TfR1) which is highly expressed on muscle. It is designed to enable targeted muscle tissue delivery and promote exon skipping in the nucleus, allowing muscle cells to create internally shortened, near full-length dystrophin protein, with the goal of stopping or reversing disease progression. DYNE-251 has been granted fast track, orphan drug and rare pediatric disease designations by the U.S. Food and Drug Administration for the treatment of DMD mutations amenable to exon 51 skipping. In addition to DYNE-251, Dyne is building a global DMD franchise and has preclinical programs targeting other exons, including 53, 45 and 44. About Duchenne Muscular Dystrophy (DMD) DMD is a rare disease caused by mutations in the gene that encodes for dystrophin, a protein critical for the normal function of muscle cells. These mutations, the majority of which are deletions, result in the lack of dystrophin protein and progressive loss of muscle function. DMD occurs primarily in males and affects an estimated 12,000 to 15,000 individuals in the U.S. and 25,000 in Europe. Loss of strength and function typically first appears in pre-school age boys and worsens as they age. As the disease progresses, the severity of damage to skeletal and cardiac muscle often results in patients experiencing total loss of ambulation by their early teenage years and includes worsening cardiac and respiratory symptoms and loss of upper body function by the later teens. There is no cure for DMD, and currently approved therapies provide limited benefit.
