SOUTH SAN FRANCISCO, Calif., Jan. 18, 2012 /PRNewswire/ -- diaDexus, Inc. (OTC Bulletin Board: DDXS.OB), a diagnostics company focused on patent-protected in vitro diagnostic products addressing unmet needs in cardiovascular disease, today announced the appointment of Jean-Frederic Viret, Ph.D.  as its Chief Financial Officer, effective February 1, 2012.

Dr. Viret joins diaDexus after 12 years in finance operations of diagnostic and biotechnology companies, where he participated in and directed over $200 million in equity, debt and other strategic financings. Most recently, he was Chief Financial Officer at XDx, a diagnostics company, where he not only led multiple private financings, but also was involved in increasing insurance coverage by 30% from large private payers. Prior to XDx, Dr. Viret was at Anesiva, a publicly traded specialty pharmaceutical company, where he served in several roles of increasing responsibilities, including CFO. In particular, Jean led due diligence for all of Anesiva's public raises and debt facilities to support commercial expansion. Previously, Dr. Viret was Associate Director of Finance at Tularik, a publicly-traded biotech company that was acquired by Amgen. At Tularik, he was instrumental in integrating European operations. Prior to that, he worked for PricewaterhouseCoopers LLP on a variety of life science and venture capital accounts, primarily in financial audits but also with the emerging company services group.

"In both public and private companies, Jean has consistently shown that he can make significant contributions to shareholder value by combining operational efficiencies with capital raising efforts through a variety of financial structures. As we plan the launch of our new Activity assay in Europe this spring, and project 26% revenue growth in 2012, Jean's understanding of the value drivers for a diagnostics company will provide critical perspective for building diaDexus into a highly profitable business creating shareholder value in the process," commented Chief Executive Officer Brian E. Ward, Ph.D.

Dr. Viret earned a master in business administration from Cornell University.  He has a Ph.D. in Molecular Biology from the Universite Louis Pasteur in Strasbourg, France and a B.S.in Engineering from the Institut National Polytechnique de Lorraine, in Nancy, France.
