SAN DIEGO, Jan. 30, 2012 /PRNewswire/ -- Cardium Therapeutics (NYSE Amex: CXM) today reported on new insights and confirmatory preclinical study results on the Generx (Ad5FGF-4) angiogenic therapy product candidate based on the Company's sponsored research conducted at Emory University. The findings, which provide further support for the apparent safety and effectiveness of Generx as a potential one-time non-surgical approach to the treatment of coronary heart disease, are being presented at the Phacilitate Annual Gene and Cell Therapy Forum held January 30 – February 1, 2012 in Washington, DC.
The recent preclinical findings demonstrate that induced transient ischemia, using a standard angioplasty balloon catheter, combined with the intracoronary co-infusion of nitroglycerin, substantially enhanced adenovector-mediated gene delivery to the heart. These findings have been incorporated into the protocol for the planned 100-patient Generx (Ad5FGF-4) ASPIRE Phase 3 registration study which, as previously reported, is expected be initiated in the first quarter 2012. The YouTube video "Cardium Generx Cardio-Chant" provides an overview of the Company's Generx (Ad5FGF-4) product candidate, at http://www.youtube.com/watch?v=pjUndFhJkjM.
The new data underscore the expected benefit of Cardium's improved adenovector administration methods that combine non-surgical, percutaneous balloon catheter-based delivery with transiently-induced ischemia and nitroglycerin to enhance uptake leading to improved microvascular circulation in the heart. By increasing cell transfection efficiency, this modified approach allows for effectively obtaining additional targeted expression of growth factors within the ischemic heart, where the resulting angiogenesis or blood vessel growth can bring about improved blood flow throughout the ischemic myocardium. Traditional interventional cardiology approaches such as coronary artery bypass surgery (CABG) or angioplasty and stenting (PCI), not only require invasive and costly surgical procedures but they can only directly target selected vulnerable spots in larger vessels that are susceptible to treatment and reachable through mechanical intervention.
