Champions Biotechnology, Inc. and Morphotek®, Inc. Announce Agreement for an Oncology Evaluation Using Biomerk Tumorgraft Platform

Hackensack, NJ – April 20, 2010 – Champions Biotechnology, Inc. (OTC Bulletin Board : CSBR), a company with a predictive preclinical platform aimed at accelerating the development of oncology drugs, and Morphotek®, Inc., a subsidiary of Eisai Inc., have established an agreement to test one of Morphotek’s oncology monoclonal antibodies using Champions’ Biomerk Tumorgraft platform.

Under the terms of the agreement, Champions will use its Biomerk Tumorgraft to test the efficacy of Morphotek’s monoclonal antibody as a single agent and in combination with other oncology agents.

“The use of Biomerk Tumorgrafts preclinically may allow for a greater understanding about the potential of these compounds in a clinical setting,” stated Elizabeth Bruckheimer, Ph.D., vice president of scientific operations, Champions Biotechnology, Inc. “These results may be critical in designing clinical trials that will further support the clinical development for Morphotek’s oncology antibody.”

Morphotek develops monoclonal antibodies that target antigens expressed by tumor cells or tumor-associated cells. These unique cancer-specific targets have been demonstrated to be associated with diseased tissues identified by Morphotek or academic collaborators at leading cancer research institutes around the world.

“We are excited to be working with Champions,” said Luigi Grasso, Ph.D., chief scientific officer, Morphotek, Inc. “The Biomerk Tumorgraft platform has the potential to facilitate the prediction of sensitivity and resistance in the clinic and could play an important role in our oncology drug development.”
