GAITHERSBURG, Md., Dec. 8 /PRNewswire-FirstCall/ -- MedImmune, Inc. announced today that it continues to build upon its corporate initiatives to expand and expedite the development of its product pipeline by licensing rights to antibody-enhancing technologies. The latest technology agreements MedImmune has entered into are with BioWa, Inc. and Xencor, Inc. from which MedImmune has gained access to two different technologies that may enhance the effectiveness of monoclonal antibodies (MAbs) targeting cancer.

"As a leader in the biotechnology industry dedicated to advancing science for better health, MedImmune aims to maintain its competitive edge by investing in technologies that will help develop successful biopharmaceutical therapies," commented Peter Kiener, D.Phil., MedImmune senior vice president, research.

MedImmune's recent technology licensing agreements include:

Avidia, Inc. -- MedImmune intends to combine its growing expertise in the field of tyrosine kinase research with Avidia's Avimer technology to develop anti-cancer product candidates that may have several advantages over antibodies in terms of biological activity, tissue distribution, reduced immunogenicity and improved manufacturing efficiencies. The two companies are also collaborating on the development of anti-cancer products targeting cMET, a receptor tyrosine kinase found in high levels in certain cancer cells.

Avalon Pharmaceuticals, Inc. -- MedImmune and Avalon are using Avalon's proprietary drug discovery technology, the AvalonRx(R) drug discovery engine, to collaborate on discovery and optimization of small molecule therapeutic compounds for the prevention and treatment of debilitating disease.

BioWa, Inc. -- MedImmune licensed the right to use BioWa's POTELLIGENT technology as a method for maximizing the potential of therapeutic antibodies targeting cancer.

Seattle Genetics, Inc. -- MedImmune in-licensed Seattle Genetics' antibody-drug conjugate, which utilizes the targeting ability of MAbs to deliver cell-killing payloads to specific cells.
