Advanced BioHealing Raises $25.5 Million in Series C Financing LA JOLLA, Calif., Feb. 27, 2007 -- Advanced BioHealing, Inc. (ABH) today announced that it has raised $25.5 million in a Series C round of financing. The round was led by Safeguard Scientifics, Inc. , a provider of capital in growth-stage technology and life sciences businesses. This latest round of financing brings the total amount raised by the company, since its inception in 2003, to approximately $36 million. In addition to Safeguard Scientifics, Inc., other investors include Channel Medical Partners and Red Abbey Venture Partners, LP, as well as existing investors Canaan Partners and Wheatley Partners. In conjunction with this financing, Gary J. Kurtzman, M.D., Vice President of Life Sciences at Safeguard and Carol D. Winslow, Founder and Principal of Channel Medical Partners will join the ABH Board of Directors. Pacific Growth Equities, LLC served as financial advisors to ABH. "I am pleased by the overwhelming interest in ABH and thank our new investors, as well as current shareholders for their on-going support," said Kevin Rakin, Chief Executive Officer of Advanced BioHealing. "ABH has made significant progress during the past year, culminating in the recent market launch of Dermagraft(R) and the advancement of our next-generation bioengineered product, Celaderm(TM), into clinical trials. I look forward to working closely with our investor group as we collaborate to build a strong business in regenerative medicine." Proceeds from the financing will be used to execute the launch and expand the market for Dermagraft, approved by the U.S. Food and Drug Administration (FDA) as a treatment for full-thickness diabetic foot ulcers. Funding will also support the Company's clinical trials program, in-licensing activities and international expansion. Earlier this month, ABH announced the launch of Dermagraft and is focused on establishing the product in proven markets, as well as opportunities in other geographic regions of the United States, including specialized wound care centers. The Company's next generation bioengineered product, Celaderm, is in a pilot study for venous leg ulcers. If successful, Celaderm will move directly into a trial to determine clinical efficacy. "Innovative research is paving the way for a transformation in how we treat disease, as well as how we discover and develop drugs," said Gary J. Kurtzman, M.D. "ABH is at the forefront of this cutting-edge technology, having already launched Dermagraft, as well as its first human clinical trial for Celaderm. We believe that ABH has a unique position in this market of next generation bioengineered wound therapy products." Stephen Bloch, M.D., Chairman of ABH's board and a Canaan Partners' venture partner, remarks, "there is a great business story evolving with ABH. ABH is creating a new generation of regenerative medicine solutions. In a short time, we have been able to build a robust pipeline of high impact clinical products. I have met scores of physicians who are thrilled to again have access to Dermagraft, a unique and highly regarded advanced wound care product." About Safeguard Scientifics, Inc.
