diaDexus, Inc. Appoints Pat Arensdorf to Lead Heart Failure Business

SOUTH SAN FRANCISCO, Calif.--()--diaDexus, Inc. (OTCQB:DDXS), a company developing and commercializing proprietary cardiovascular diagnostic products, today announced the appointment of Pat Arensdorf as general manager and head of the heart failure business unit with responsibility for the development and commercialization of the company’s heart failure biomarkers.

“Our emerging heart failure program will begin a new, accelerated stage of development with Pat’s leadership,” said Lori Rafield, Ph.D., interim executive chair and chairman of the board for diaDexus. “Pat has extensive experience developing and commercializing cardiovascular diagnostic products in both clinic and laboratory settings. As we evolve from a single-product business to a multi-product company, these biomarkers will become important drivers of our future growth. We are planning to move our first heart failure marker proADM into development by the end of this year.”

“I look forward to developing the heart failure business at diaDexus to deliver these important new prognostic tools for physicians’ management of heart failure patients that provide information independent of already commercialized cardiovascular risk markers,” said Pat Arensdorf. “These biomarkers already have extensive published clinical evidence supporting their clinical utility over the current standard of care. I am committed to leading and growing this new business as an important new product pipeline offering and a significant value creation opportunity for diaDexus.”

Mr. Arensdorf has more than 20 years of experience in the medical technology industry. Prior to joining diaDexus, he has been an active executive, founder and advisor to companies ranging from early-stage startups to large established multinationals, including both commercial and not-for-profit non-governmental organizations. Most recently, he was chief executive officer of Critical Diagnostics, where he led a new regulatory strategy resulting in the most recent FDA clearance of a novel heart failure biomarker. He has been involved in the founding strategies, corporate development and financing of several companies from concept through product launch, including Immumetrix (transplant diagnostics; acquired by CareDx), Tethys Bioscience (cardiometabolic clinical laboratory and pre-diabetes test developer; acquired by Health Diagnostic Laboratory) and Intersect ENT (medical devices). His career in cardiovascular diagnostics began at First Medical, a pioneer in cardiac marker point-of-care testing, which he led as chief executive officer through a venture-backed restart, business acquisition and subsequent product launch as part of Sigma-Aldrich Corporation. Mr. Arensdorf received his master’s degree from the Stanford Graduate School of Business and bachelor’s degree in molecular biology from Princeton University.
