LOS ANGELES, Nov. 18, 2014 (GLOBE NEWSWIRE) -- Capricor Therapeutics, Inc. (OTCBB:CAPR), a biotechnology company focused on developing novel therapeutics for the treatment of cardiovascular diseases, today announced positive data from the laboratory of Eduardo Marbán, M.D., Ph.D., Capricor's Scientific Advisory Board Chairman and the Director of the Cedars-Sinai Heart Institute. The abstract was presented at the Late Breaking Basic Science Posters and Reception at the American Heart Association's Scientific Sessions 2014 on November 17, 2014.
Capricor's Cardiosphere-derived cells (CDCs), also known as CAP-1002, promote cardiomyogenesis and angiogenesis, while inhibiting oxidative stress, inflammation and fibrosis. Dr. Marbán tested the hypothesis that CDC transplantation may be beneficial in mice with muscular dystrophy (mdx mice), which progressively develop cardiomyopathy due to dystrophin deficiency and the resultant intense oxidative stress, inflammation and apoptosis.
Methods and Results: A total of 56 mice were studied at a point when global cardiac dysfunction was already evident by echocardiography. Wild-type syngeneic mouse CDCs (105 cells total) or control were injected intra-myocardium in 5 left ventricular (LV) sites in 10-month old mdx mice.
- LV ejection fraction markedly improved 3 weeks after treatment in CDC-treated mice compared to vehicle-treated mice (60.4±1.6 vs 48.1±2.2; p<0.005).
- CDC-treated mdx mice exhibited higher maximal exercise capacity compared to vehicle-treated mice over 3 months of follow up (p<0.05).
- The functional improvement was associated with enhanced Nrf2 activation, up-regulation of Nrf2 downstream gene products, increased expression of mitochondrial transcription factor A and cellular mitochondrial content, restored expression of mitochondrial respiratory complex proteins, reduced collagen I and III deposition, and attenuated infiltration of inflammatory cells [CD68+ macrophages and CD3+ T cells] in the CDC-treated mouse hearts.
The data demonstrated that cardiac function and exercise capacity improved in CDC-treated mdx mice, accompanied by enhanced activation of the antioxidative Nrf2 pathway, attenuation of inflammation, reduction in collagen content and fibrosis, and augmented cardiomyogenesis in CDC-treated mdx hearts. The findings raise the possibility that CDCs may be useful therapeutically to treat heart failure in patients with Duchenne muscular dystrophy.
Dr. Linda Marbán, Chief Executive Officer of Capricor, said, "Data presented yesterday forms the basis for a clinical development plan that we intend to submit to FDA. Duchenne cardiomyopathy is a devastating complication of the disease that affects virtually all those affected by the disease and is the leading cause of death in patients with Duchenne Muscular Dystrophy. Notwithstanding the advances being made for the skeletal muscle symptoms of Duchenne, Capricor is addressing the devastating cardiac complications for which there is no specific treatment."
About Duchenne Muscular Dystrophy (DMD)
DMD afflicts approximately 25,000 boys and young men in the USA. The central cause is a genetic abnormality in the dystrophin complex, leading to membrane fragility with secondary damage to skeletal and cardiac muscle. No treatment has been proven effective for DMD; patients usually die in young adulthood. Various clinical trials are ongoing, but almost all target the skeletal myopathy. Much of the death and disability in the later years of DMD is due to heart disease rather than to skeletal muscle disease. Virtually all DMD patients aged >15 years develop heart failure, and mortality is high (10-20% per year) despite optimal medical therapy. Heart transplantation is not typically an option for DMD patients.
