Cardiogenesis Reacts to Published Research Demonstrating Potential of TMR Plus Gene Therapy.

FOOTHILL RANCH, Calif. -- Company Sites that AHA Supported Research Study Shows that Angiogenesis Resulting from TMR Plus AdFGF-2 is Greater Than Either Therapy Individually

Cardiogenesis Corporation (OTCBB:CGCP:OB), a leading developer of surgical products and accessories used in angina-relieving procedures, issued the following statement today in reaction to a study published in the current issue of The Journal of Thoracic and Cardiovascular Surgery.

According to Michael Quinn, Chairman and CEO of Cardiogenesis: "As highlighted by this noteworthy research, we believe that the future of TMR lies in minimally-invasive, closed-chest delivery tools and techniques, with potentially synergistic delivery of biologic enhancements. The impressive work by Dr. Horvath and his co-authors, as supported by the American Heart Association and Selective Genetics Inc., is advancing the understanding of TMR's potential beyond the demonstrated significant patient benefits as a primary or sole therapy. We are encouraged by his continued contribution in advancing the scientific understanding and clinical application of TMR, and in helping to advance therapies to the growing group of patients suffering from advanced heart disease who have limited therapeutic options."

Cardiogenesis's products and systems specifically are used for Transmyocardial Revascularization (TMR) and Percutaneous Myocardial Channeling (PMC) procedures.

The study shows a significant increase in angiogenesis within the heart as a result of a combination of TMR and matrix adenoviral fibroblast growth factor-2 (AdFGF2) gene therapy. The results demonstrated a clear improvement versus either therapy conducted alone.

In the article entitled, "Improvement of Myocardial Contractility in a Porcine Model of Chronic Ischemia using a Combined Transmyocardial Laser Revascularization and Gene Therapy Approach," the authors state "(t)he key limitation of growth factor protein therapy seems to be the difficulty in achieving sustained therapeutic protein concentrations at the intended sites."

The study's design used a chronic ischemic porcine model in comparing the response of four treatment groups-TMR alone, adenoviral FGF-2 in a collagen-based matrix alone, adenoviral FGF-2 in a collagen-based matrix combined with TMR, and saline-formulated adenoviral FGF-2. The authors reported that histological analysis confirms the matrix formulated vectors present in TMR channels post treatment and that arteriogenesis is enhanced in the TMR plus AdFGF2 treated areas compared to either therapy alone. They concluded the combination therapy provides a "salutary angiogenic response that has significant clinical implications and in planned translational work may provide a better treatment in combination than either therapy alone."
