PRINCETON, New Jersey, December 8 /PRNewswire/ --

BioWa, Inc., announced today that it licensed to GlaxoSmithKline (NYSE: GSK) its POTELLIGENT(R) Technology for use in developing and commercializing select GSK antibodies with enhancement of antibody-dependent cellular cytotoxicity (ADCC).

GSK is recognized as a key player in the field of antibody drug discovery, said Dr. Masamichi Koike, BioWa President and CEO. We believe this represents an important opportunity to promote the development of more effective targeted treatments for debilitating diseases where enhanced ADCC might offer a significant therapeutic benefit.

Under the terms of the agreement, BioWa will provide GSK with non-exclusive commercial rights to use the technology for multiple antibodies. In return, BioWa will receive technology access fees, and may receive milestone payments and royalties from resulting products which are developed by GSK. Additional terms were not disclosed.

About POTELLIGENT(R) Technology

POTELLIGENT(R) Technology improves potency and efficacy of antibody therapeutics, by enhancing ADCC, one of the major mechanisms of action for antibody therapeutics. POTELLIGENT(R) Technology involves the reduction of the amount of fucose in the carbohydrate structure of an antibody using a proprietary fucosyltransferase-knockout CHO cell line as a production cell. Research shows that POTELLIGENT(R) Technology dramatically enhances ADCC activity of an antibody in vitro, and significantly increases potency and efficacy of the antibody in vivo. A number of POTELLIGENT(R) antibodies are being investigated in human clinical trials.
