Biolex Therapeutics Announces Expansion of Medarex Collaboration

Agreement Expanded to Include Three Medarex Monoclonal Antibodies

PITTSBORO, N.C., April 11 (HSMN NewsFeed) -- Biolex Therapeutics today announced the expansion of its collaboration with Medarex, Inc., an antibody therapeutics company. The collaboration was initially formed in February of 2005 to create a commercial line for an undisclosed Medarex monoclonal antibody using the Biolex LEX System(SM). As a result of the successful achievement of the scientific goals for the first monoclonal antibody, the collaboration has been expanded to include commercial line creation for two additional Medarex antibodies.

"The fact that Biolex continues to build upon and expand collaborations formed with leading monoclonal antibody companies is proof of the value and benefits of producing these important proteins with the LEX System," said Jan Turek, President and CEO of Biolex. "We have enjoyed working with Medarex and are very pleased that they are happy with the successful results we have achieved to date with their first monoclonal antibody. We plan to continue building upon and forming similar agreements with other pharmaceutical and biotech companies, while advancing our own pipeline of therapeutic proteins."

Biolex will conduct commercial line creation projects using its proprietary LEX System for each of these two additional Medarex antibodies. At Medarex's option, it may elect to engage Biolex to scale-up and manufacture these proteins following the commercial line creation phase.
