Casamento to fill a vacant seat on the Board and to serve as Chairman of the Audit Committee of the Board, as a member of the Compensation Committee of the Board, and as a member of the Nominating and Corporate Governance Committee of the Board. The Board has determined that Mr. Casamento qualifies as an independent director as that term is defined in the applicable rules for companies traded on The NASDAQ Stock Market.


Mr. Casamento is currently an executive director and principal of The Sage Group, a healthcare advisory group specializing in mergers, acquisitions, and partnerships between biotechnology companies and pharmaceutical companies, since 2007.

He was co-founder, president and CEO of Interneuron Pharmaceuticals, Inc. (Indevus), a biopharmaceutical company, from 1989 until 1993. Indevus was eventually acquired by Endo Pharmaceuticals. Mr. Casamento has also held senior management positions at Genzyme Corporation, where he was senior vice president, pharmaceuticals and biochemicals; American Hospital Supply, where he was vice president of business development and strategic planning for the Critical Care Division; Johnson & Johnson, Hoffmann-LaRoche, Inc. and Sandoz Inc.

During his career he has served on the boards of fourteen Biotech/Pharma companies and has also been a director and vice chairman of The Catholic Medical Missions Board, a large not-for-profit organization providing health care services to third world countries. He has served as a guest lecturer at Fordham University and is on the Science Council of Fordham University. He holds a bachelor’s degree in Pharmacy from Fordham University and an MBA from Iona University and was originally licensed to practice pharmacy in the states of New York and New Jersey.
