Semprus BioSciences to Present at SIR's 36th Annual Scientific Meeting

Christopher Loose, Ph.D., to Present New Data on Semprus Platform

CAMBRIDGE, MA - (March 14, 2011) - Semprus BioSciences today announced its Chief Technology Officer Christopher Loose, Ph.D., will present the company's groundbreaking data results on its non-fouling Semprus Platform at the Society of Interventional Radiology's (SIR) 36th Annual Scientific Meeting in Chicago, Ill., on Monday, March 28, 2011.

Dr. Loose will present Semprus' data on its single-surface modification that demonstrate simultaneous reduction of microbial and platelet adhesion over multiple months. These data showcase the technology's three distinctive aspects: its dual-functionality, its ability to work in blood products, and its long-term durational advantages over existing surface and coating technologies.

SIR's Annual Meeting is a recognized forum for peer-reviewed presentations of new research by interventional radiologists and allied scientists from around the world. It provides a host of news and educational opportunities ranging from scientific presentations and news conferences to hands-on workshops and technical exhibits.

Semprus BioSciences is a venture-backed biomedical company with a dual mission: to provide complication-free medical devices designed to preserve patients' long-term health and quality-of-life and to contribute to healthcare cost efficiencies. The company's current focus is to develop a vascular access catheter with the first single surface modification that is designed to simultaneously reduce microbial adherence and thrombus accumulation over the life of the device. The company spun out of the labs of biomedical researcher and Massachusetts Institute of Technology (MIT) Professor Robert Langer, Sc.D., in 2007.

"It's a great privilege for us to present our novel technology at SIR's annual meeting," said Chief Executive Officer David L. Lucchino. "We are very proud of our technology and excited to highlight the aspects that distinguish it from other surface and coating technologies currently on the market."

Dr. Loose will present at the Venous Access/Thrombolysis Scientific Session on Monday, March 28, at 8:30 a.m. in Room W181C, McCormick Place West Building.
