QUICK JUMP:

In October 2003, Verenium and Medarex announced a strategic partnership aimed at developing antibodies with enhanced functionality. Through a joint research effort, Verenium and Medarex planned to combine their respective capabilities in directed evolution and antibody biology. The companies cosponsored this project, and believe it may have broad applications in the field of therapeutic antibodies.

Medarex’s preclinical capabilities and expertise in immune cell receptor function are an excellent complement to Verenium’s antibody engineering capabilities to accelerate the development of optimized, highly-effective antibody-based drug candidates.
