Exosome Diagnostics Announces Additions to Management and Scientific Advisory Board as Company Expands Clinical Validation Studies in Oncology

NEW YORK Oct. 4, 2011 - Exosome Diagnostics, a leading developer of biofluid-based molecular diagnostic tests for use in personalized medicine, today announced the appointment of Michael Donovan, MD, PhD, as chief medical officer, and Sally Bowden as director of regulatory affairs. Raphael Bueno, MD, associate chief of cardiothoracic surgery Harvard University and Michael Manyak, MD, FACS, executive director global medical affairs at GlaxoSmithkline were named to the Scientific Advisory Board.

"The collective professional experiences of Dr. Donovan and Ms. Bowden are invaluable management additions as we expand clinical studies for our lead exosome biofluid RNA diagnostics," said chief executive officer James McCullough. "The addition of Dr. Bueno and Dr. Manyak to our Scientific Advisory Board builds on our strategy of working closely with top clinical investigators to more accurately assess how exosome technology can be best applied to address unmet medical needs."

Dr. Donovan is board certified in anatomic and clinical pathology and pediatric pathology with extensive experience designing and conducting clinical trials in melanoma and prostate cancer. Prior to joining Exosome Diagnostics, he held positions as chief scientific officer for Aureon Biosciences, assistant professor at Harvard Medical School, senior director of Molecular Pathology at Millennium Pharmaceuticals, and senior vice president at Incyte Genomics. At Millennium, he was involved with the clinical development of Velcade®, the first proteasome inhibitor approved for clinical use. He also contributed to the expanded of use of Tarceva in glioblastoma multiforme, and the development of Iressa in non-small cell lung cancer. Dr. Donovan received his MD from the University of Medicine and Dentistry of New Jersey, and his PhD in cell and developmental biology from Rutgers University. Dr. Donovan has recently joined the faculty at Mt. Sinai School of Medicine as a Professor in the Department of Pathology and Genetics and will also serve as director of Experimental Pathology.

Ms. Bowden has over 20 years of experience in the quality and regulatory field in medical devices, companion diagnostics, education and health care systems.

About Exosome Diagnostics
Exosome Diagnostics is a leading developer of biofluid based molecular diagnostic tests for use in personalized medicine. Exosomes are shed into all biofluids, including blood, urine, and CSF, forming a stable source of intact, disease-specific nucleic acids. The Company's proprietary exosome technology makes use of this natural stability to achieve high sensitivity for rare gene transcripts and the expression of genes responsible for cancers and other diseases. The Company is commercializing in-vitro diagnostic tests for use in companion diagnostic applications and real-time monitoring of disease. The Company maintains facilities in New York, St. Paul, MN and Munich, Germany. For more information, please visit
