Cardium Announces Plans to File FDA 510(k) Application for U.S. Marketing Clearance of ExcellagenXL(TM) Gel for Diabetic, Pressure and Venous Ulcers and Other Topical Wounds

SAN DIEGO, Nov. 2 /PRNewswire-FirstCall/ -- Cardium Therapeutics (NYSE Amex: CXM) today announced plans to submit a 510(k) premarket notification with the U.S. Food and Drug Administration (FDA) seeking marketing clearance of its ExcellagenXL(TM) product candidate. ExcellagenXL is an advanced wound care management medical device, which is a customized collagen-based topical gel designed for use by physicians in patients with topical wounds, which include diabetic ulcers as well as pressure ulcers, venous ulcers, surgical and trauma wounds, second degree burns, and other types of wounds. The Company expects to submit its FDA 510(k) application for ExcellagenXL during the current quarter.

The planned 510(k) filing is based in part on positive findings from the Company's Phase 2b Matrix clinical study, reported October 14, 2009, indicating that substantial improvements in wound healing responses were observed in patients with non-healing diabetic foot ulcers following one or two applications of ExcellagenXL. The ExcellagenXL topical gel wound care product is designed to promote a favorable environment for effective wound management by providing a moist protective barrier as well as a micro-scaffold that promotes cell migration and capillary in-growth.

ExcellagenXL is an advanced wound care device composed of highly-refined, soluble bovine dermal collagen (Type I), which is modified to reduce immunogenicity and promote its usefulness in wound settings. ExcellagenXL is planned for physician use in conjunction with standard of care wound therapy, which in the case of diabetic ulcers typically includes surgical debridement and off-loading. ExcellagenXL is expected to be indicated for use at two-week intervals (with weekly outer dressing changes) as an adjunct to surgical debridement, and supplied in a sterile single-use syringe along with a sterile flexible application needle to facilitate topical administration over the wound site. ExcellagenXL will be stored at standard refrigeration temperature (2 degrees C - 8 degrees C).

Cardium also announced plans to develop additional new product opportunities by incorporating other agents into Excellagen formulations, including antimicrobials, DNA and/or other biologics, which are designed to address particular wound healing and other tissue repair applications.

"We are pleased to announce plans to submit our FDA 510(k) premarket notification of our ExcellagenXL collagen-based topical gel. The 510(k) clearance process provides us with a potential near-term opportunity to introduce this product into the rapidly-growing market for advanced wound care. Applying our specialized formulation know-how and the unique properties of our collagen-based matrix technology, we also look forward to introducing additional Excellagen-based products in the near future," stated Christopher J. Reinhard, Chairman and Chief Executive Officer of Cardium.

Actual results may also differ substantially from those described in or contemplated by this press release due to risks and uncertainties that exist in our operations and business environment, including, without limitation, risks and uncertainties that are inherent in the development of complex biologics and in the conduct of human clinical trials, including the timing, costs and outcomes of such trials, our ability to obtain necessary funding, regulatory approvals and expected qualifications, our dependence upon proprietary technology, our history of operating losses and accumulated deficits, our reliance on collaborative relationships and critical personnel, and current and future competition, as well as other risks described from time to time in filings we make with the Securities and Exchange Commission.
