Capricor Therapeutics Announces Positive Six-Month Results from the Randomized Phase I/II HOPE Clinical Trial in Duchenne Muscular Dystrophy

Capricor Therapeutics today announced positive top-line results from a safety and exploratory efficacy analysis of six-month data from the randomized 12-month Phase I/II HOPE Clinical Trial of CAP-1002 (allogeneic cardiosphere-derived cells), an investigational candidate for the treatment of patients with Duchenne.

We are excited to see these results and to see the field of cell therapy making progress after more than two decades in development.

Later this week, PPMD and Coalition Duchenne will host a community webinar with the Capricor team to discuss this study. Details coming soon.

Capricor Therapeutics Announces Positive Six-Month Results from the Randomized Phase I/II HOPE Clinical Trial in Duchenne Muscular Dystrophy

Statistically-Significant Improvements in Measures of Cardiac and Upper Limb Function in Patients Treated with CAP-1002
Capricor to Seek Breakthrough Therapy or Regenerative Medicine Advanced Therapy Designation
Conference Call and Webcast to be Held Today at 8:00 a.m. Eastern Time

LOS ANGELESApril 25, 2017 /PRNewswire/ -- Capricor Therapeutics, Inc. (NASDAQ: CAPR), a clinical-stage biotechnology company developing first-in-class biological therapies for cardiac and other medical conditions, today announced positive top-line results from a safety and exploratory efficacy analysis of six-month data from the randomized 12-month Phase I/II HOPE Clinical Trial of CAP-1002 (allogeneic cardiosphere-derived cells), an investigational candidate for the treatment of patients with Duchenne muscular dystrophy, or DMD. Duchenne muscular dystrophy is a rare, life-threatening genetic disorder for which treatment options are limited.

Highlights from the Phase I/II HOPE Clinical Trial six-month results:

  • In a 25-patient, randomized, single-dose, three-center clinical trial being conducted in a DMD population with advanced cardiac disease, patients treated with CAP-1002 demonstrated statistically-significant (p<0.05) improvement compared to usual care controls in certain measures of cardiac and upper limb function.
  • CAP-1002 was generally safe and well-tolerated over the initial six-month follow-up period.
  • Clinical results corroborate a large body of preclinical data from studies in DMD models.
  • Capricor has submitted a meeting request to the U.S. Food and Drug Administration, or FDA, to discuss potential product registration strategies for CAP-1002 in the DMD indication.
  • Capricor intends to submit HOPE-Duchenne data to FDA and to request Breakthrough Therapy or Regenerative Medicine Advanced Technology, or RMAT, designations for CAP-1002. The RMAT designation, intended to expedite the approval of safe and effective cell therapies, was created by the U.S. Congress as part of the recently-enacted 21st Century Cures Act.


John L. Jefferies
, M.D., Professor of Pediatric Cardiology and Adult Cardiovascular Diseases at the University of Cincinnati and Director, Advanced Heart Failure and Cardiomyopathy, and Principal Investigator of the HOPE Trial, said, "In HOPE, we saw potential effects in both the heart and skeletal muscle that appear quite compelling in an exploratory trial. These results clearly support the conduct of a confirmatory clinical trial in DMD to further evaluate the potential of CAP-1002. We look forward to an effective medication becoming available for people with this progressive and fatal disease, one that is poorly met by current options."

Joao A. C. Lima, M.D., Professor of Medicine and Director of the Magnetic Resonance Imaging, or MRI, Core Lab at The Johns Hopkins University School of Medicine, said, "The observed signal in global cardiac scar reduction and the increase in the thickening of the left ventricle during contraction are very encouraging. The population treated in HOPE had very advanced cardiac involvement, and to see such positive results following just a single dose of CAP-1002 is remarkable. Cardiac disease is the most common cause of mortality among those with DMD."

Pat Furlong, Founding President and CEO of Parent Project Muscular Dystrophy, the largest nonprofit organization in the U.S. solely focused on DMD, said, "I'm excited to see these data, especially given the advanced nature of the patients in the HOPE trial. It is also gratifying to see the field of cell therapy making progress after more than two decades in development. It is our hope that CAP-1002 will have broad potential to improve the lives of patients with Duchenne muscular dystrophy."

The randomized HOPE (Halt cardiomyOPathy progrEssion in Duchenne) Clinical Trial was designed to evaluate the safety and exploratory efficacy of CAP-1002 in patients 12 years and older with DMD who had cardiomyopathy, or heart disease, secondary to DMD as evidenced by scar in four or more left ventricular segments as detected by late gadolinium-enhancement MRI. Twenty-five patients were randomized to receive either a single dose of CAP-1002 (13 patients) or usual care (12 patients). CAP-1002 was infused into each of the three main coronary arteries at a total dose of 75 million cells.

All cardiac assessments were performed by MRI. A validated test of upper limb function, the Performance of the Upper Limb test, or PUL, was used to assess skeletal muscle performance. The PUL was designed specifically for use in the DMD setting, and evaluates a variety of manual tasks, such as lifting cans, tearing paper, and removing a container lid, which simulate activities of daily living. Boys and young men with advanced DMD have difficulty with such common activities as feeding themselves and brushing their teeth.

CAP-1002 has been well-tolerated in the HOPE trial. During and immediately following CAP-1002 infusion, no treated subjects experienced a pre-specified composite safety endpoint, which included the major adverse cardiac events of death, myocardial infarction, or hospitalization for a cardiovascular event. There were no early study discontinuations due to adverse events.

In exploratory efficacy analyses, statistically-significant improvements in systolic thickening of the inferior wall of the heart (p=0.030), and in the function of the middle and distal upper limb according to a PUL responder analysis (p=0.045), were observed in patients treated with CAP-1002 as compared to usual care control patients. In addition, differences observed in several other cardiac and skeletal muscle measures, including cardiac scar (p=0.09), are consistent with a treatment effect. At three months, a statistically-significant difference in quality-of-life (p=0.03), according to the PODCI Adolescent Questionnaire, that favored the CAP-1002 arm was also observed. A more comprehensive summary of the top-line data will be provided in slides to be presented during today's webcast.

"These initial positive clinical results build upon a large body of preclinical data which illustrate CAP-1002's potential to broadly improve the condition of those afflicted by DMD, as they show that cardiosphere-derived cells exert salutary effects on cardiac and skeletal muscle," said Linda Marbán, Ph.D., Capricor's president and chief executive officer.

"We have submitted an FDA meeting request to discuss these results as well as next steps in our development of CAP-1002 for Duchenne muscular dystrophy, which includes our plan to begin a clinical trial of intravenously-administered CAP-1002 in the latter half of this year. We believe the interim HOPE results may enable us to pursue one of the FDA's Expedited Programs for Serious Conditions, and we will apply for either or both of the Breakthrough Therapy and Regenerative Medicine Advanced Therapy (RMAT) designations for CAP-1002," added Dr. Marbán.

Capricor expects to report top-line 12-month results from the HOPE-Duchenne Trial in the fourth quarter of 2017.

The HOPE-Duchenne trial is funded in part by the California Institute for Regenerative Medicine.

About CAP-1002

CAP-1002 consists of allogeneic cardiosphere-derived cells, or CDCs, a type of cardiac progenitor cell. CDCs have been the subject of over 100 peer-reviewed scientific publications and have been administered to approximately 140 human subjects across several clinical trials. CAP-1002 is currently being evaluated in the randomized, double-blind, placebo-controlled Phase II ALLSTAR Clinical Trial in adults who have suffered a large heart attack and in the Phase I/II HOPE Clinical Trial in boys and young men with DMD.
