SAN DIEGO & MINNEAPOLIS--(BUSINESS WIRE)-- <\/p>\n
Cytori Therapeutics (CYTX) announced the initiation of the FDA approved ATHENA clinical trial to investigate Cytoris cell therapy in patients who suffer from a severe form of refractory (untreatable) heart failure due to chronic myocardial ischemia. Cytoris cell therapy is based on a patients own adipose-derived stem and regenerative cells (ADRCs) processed by the Companys proprietary Celution System technology, making this the first FDA approved trial in the U.S. to evaluate ADRCs for cardiovascular disease. This first patient was treated by co-principal investigator Timothy Henry, M.D., Director of Research, at the Minneapolis Heart Institute Foundation in September and has undergone a seven day follow-up assessment. More details on the ATHENA trial may be found at http:\/\/www.theathenatrial.com<\/a>. <\/p>\n Patients with refractory heart failure have no options except for heart transplant, for which there are few hearts available, said Dr. Henry. Cell therapy such as Cytoris has the potential to delay, halt, or even reverse this progression. We believe this is accomplished by the cells ability to promote angiogenesis and regulate the immune response to help revive damaged tissue that is alive yet not necessarily contributing to its fullest capacity toward the pumping ability of the heart. <\/p>\n ATHENA is a device-based, multi-center, prospective, randomized, double-blind PMA\/IDE safety and feasibility (Phase I\/II) trial that will enroll 45 patients in six centers in the U.S. Patients will be randomized to receive either Cytoris cell therapy (n=30) or an inactive placebo injection (n=15). All trial participants will undergo a minor liposuction procedure to remove adipose tissue. The adipose tissue will then be processed at the point-of-care with Cytoris proprietary system to separate and concentrate clinical-grade ADRCs. The treatment group will have a prescribed dose of the patients own ADRCs (0.4 million cells\/kg body weight), which will then be injected into their damaged heart tissue using a minimally invasive catheter system. <\/p>\n Cytoris cell therapy has unique advantages compared to alternate cell sources such as bone marrow and peripheral blood, said Emerson Perin, M.D., Ph.D. of The Texas Heart Institute and co-principal investigator for ATHENA. Specifically, its a proprietary formulation that Cytori has optimized for vascular delivery and which contains an uncultured and mixed population of cells. As a result, this increases the number of cell types that potentially contribute to repair relative to a more homogenous population of cultured cells. <\/p>\n The trial will measure several endpoints, including peak oxygen consumption (VO2 Max). VO2 Max is an objective functional measurement that can be predictive of outcomes in heart disease, including mortality, and is commonly used as a primary determinant for qualifying patients for heart transplantation. Additional endpoints include perfusion defect, left ventricle end-systolic and diastolic volume and ejection fraction at six and 12 months. ATHENA will also evaluate medical economic factors such as rate of re-hospitalization and heart failure symptoms such as angina and quality of life at 12 months. <\/p>\n We believe Cytoris cell therapy will improve patient outcomes, said Marc H. Hedrick, M.D., president, Cytori Therapeutics. In ATHENA, investigators will be delivering a virtually off-the-shelf cell therapy comprised of a patients own cells, which is made possible by our technology. Using a patients own cells minimizes the risk of rejection or disease transmission compared to alternative therapies derived from donor cells and the virtually off-the-shelf nature allows the treatment to be accomplished in a single surgical procedure. <\/p>\n Cytori received approval from the FDA for its Investigational Device Exemption (IDE) application to begin ATHENA in January 2012 and the trial is currently expected to complete enrollment in mid-2013. In addition to Minneapolis Heart Institute Foundation, the Texas Heart Institute (Houston, TX) is actively screening patients under the direction of Emerson Perin, M.D., Ph.D., co-principal investigator for ATHENA, and James T. Willerson, M.D. Four additional centers are also expected to participate in the trial including: <\/p>\n Previously, Cytori reported six and 18-month safety and feasibility data from the PRECISE trial, a European clinical trial for this same indication. The PRECISE trial demonstrated a statistically significant improvement in VO2 Max in patients treated with Cytoris cell therapy compared to those treated with placebo. The Company is also conducting the ADVANCE trial, a European pivotal trial investigating the effect of Cytoris cell therapy in heart attack patients. <\/p>\n Refractory Heart Failure <\/p>\n<\/p>\n See the rest here: <\/p>\n First Patient Treated in Cytori\u2019s U.S. Cell Therapy Heart Failure Trial<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" SAN DIEGO & MINNEAPOLIS--(BUSINESS WIRE)-- Cytori Therapeutics (CYTX) announced the initiation of the FDA approved ATHENA clinical trial to investigate Cytoris cell therapy in patients who suffer from a severe form of refractory (untreatable) heart failure due to chronic myocardial ischemia.
