LOS ANGELES and RANCHO CORDOVA, Calif., Oct. 14, 2013 (GLOBE NEWSWIRE) -- TotipotentRX Corporation and ThermoGenesis Corp. (Nasdaq:KOOL), reported yesterday at the annual meeting of the American Association of Blood Banks in Denver, Colorado, a study confirming TotipotentRX's ground-breaking acute myocardial infarction ("AMI") combination product utilizing ThermoGenesis' point-of-care cell processing technology for an autologous bone marrow derived stem cell therapy can be delivered safely in 60 minutes.

Mr. Ken Harris, Study Director and Chief Executive Officer of TotipotentRX, presented a case study and physician feedback confirming that the Company's Acute Myocardial Infarction Rapid Stem Cell Therapy ("AMIRST") protocol utilizing autologous bone marrow derived stem cells achieved its primary safety and secondary efficacy endpoints by improving the patient's Left Ventricular Ejection Fraction ("LVEF") from 35% to 60.3% in 24 months while preventing further infarct scarring and undesirable remodeling. Low LVEF and heart remodeling are two key contributors in AMI patients advancing to heart failure.

Dr. Ashok Seth, Chairman - Cardiac Sciences, and Dr. Vinay Sanghi, both of Fortis Healthcare, conducted the clinical case study which shows the AMIRST treatment safely delivered to a single male patient an effective dose of autologous selected stem cells in a single intracoronary heart catheterization procedure. The Company believes this is the first integrated combination product treatment, consisting of a combination of devices and biologics, to be evaluated in a larger follow-up study.

The combination product and procedure developed by TotipotentRX (patent pending) incorporating ThermoGenesis' cell processing technology, is known as the AMIRST protocol. The AMIRST protocol is performed by a cardiac interventional physician in less than 60 minutes to treat acute ST-elevated myocardial infarction in patients having an LVEF below 40%. This fully integrated treatment includes:

  • a stem cell friendly process for harvesting bone marrow derived stem cells
  • an optimized stem cell dose preparation process (device & biological)
  • a rapid bedside cell analysis system (dose verification)
  • and a proprietary intracoronary catheter delivery method (device + method)

Dr. Vinay Sanghi, Clinical Investigator and treating physician on this case, said "conducting a fully-integrated point-of-care treatment on a patient with an acute ST-elevated myocardial infarction using the AMIRST protocol was straightforward and very exciting as a practicing interventional cardiologist. The safety and positive clinical benefits demonstrated in this single patient case study are very encouraging as we begin the double-blinded AMIRST study which should provide statistically significant insights".

Mr. Harris noted, "this case study affirmed that our integrated combination product has appropriately considered the essential devices, diagnostics, cell formulation, and directions for use ensuring the AMIRST treatment meets the objectives of providing a safe, effective, rapid, bedside therapy for treating low ejection fraction after a primary myocardial infarction." He continued, "we are enthusiastically looking forward to the randomized placebo controlled Phase Ib study in the coming few months. We envision this product, if approved, will improve the quality of life and mortality rates of low LVEF patients."

"We are very pleased with the initial results of this study using our combination product," said Mr. Matthew Plavan, Chief Executive Officer of ThermoGenesis. "In addition to the positive safety and efficacy data, we are particularly encouraged by the potential durability of the treatment, given this patient's LVEF exceeded 60% two years post treatment. Based upon the AMI population and those that meet the criteria for an approved AMIRST therapy, we estimate the addressable U.S. market for our combination product to exceed $500 million per year."   

This study will be advanced to a double blinded placebo-controlled randomized Phase Ib clinical trial of 30 patients (NCT01536106) in the first quarter of 2014.

About Acute Myocardial Infarction 

Cardiovascular disease ("CVD") is the number one cause of morbidity and mortality worldwide. An estimated 17.3 million people died from CVDs in 2008, representing 30% of all global deaths. Of these deaths 7.3 million were due to coronary heart disease and 6.2 million from stroke. In the progression of CVDs, plaque lesions develop in arteries that result in a narrowing of vessels, and in severe cases the vulnerable plaque breaks open and creates a blockage of blood flow to vital organs in the heart or brain. In the case of the heart, this is classified as a myocardial infarction. LVEF is one of the key indications of mortality rates post myocardial infarction with a reduced LVEF being a risk factor for both sudden and non-sudden death, with the odds ratio for 1 year mortality after myocardial infarction at 9.48 (High Rate) for patients with an LVEF 30% compared to patients with LVEF > 50%, 2.94% (Moderate Rate) for patients with LVEF 30-40%, whereas the risk is not significantly increased (low rate) in patients with LVEF 40-50%. The specific patient highlighted in this announcement was in the moderate risk category.
