Debiopharm and Cambridge Antibody Technology enter into an exclusive agreement to develop and market SC-1 for gastric carcinomas

Lausanne, Switzerland, and Cambridge, UK, October 16, 2006 – The Debiopharm Group (Debiopharm), a global independent biopharmaceutical development company specialising in oncology and serious medical conditions and Cambridge Antibody Technology (CAT) have entered into an exclusive worldwide licensing agreement to develop and commercialise SC-1 and all derivative products generated by the use of the SC-1 Technology. SC-1, developed by Debiopharm, is a fully human monoclonal IgM antibody that targets CD55SC-1, a cell surface receptor specifically expressed on gastric carcinoma cells. Under the terms of the agreement, Debiopharm will receive upfront and milestone payments from CAT as well as royalties on potential future sales.

“CAT’s expertise in the development of monoclonal antibodies gives us confidence for the future of SC-1 as a potential treatment for gastric cancer. As most patients diagnosed with stomach cancer fail to be cured by gastric resection, and most trials of pre- or post-surgery chemotherapy show no improvement in survival rates, there is a definite need for better treatment options,” said Loïc Maurel, CEO of The Debiopharm Group Canadian subsidiary.

“CAT is delighted with the agreement to develop and commercialise SC-1. This is a further step in enhancing our pipeline and builds on our recent product acquisitions in this area,” commented Dr Richard Mason, Senior Vice President Business Development at CAT

SC-1 has completed a non-IND Phase I/II study in 51 resectable gastric cancer patients. SC-1 has been granted orphan drug designation by the US FDA for gastric cancer.
