Under the terms of the agreement, the companies will share responsibilities for development and commercialization of the L1 MAb

MARTINSRIED/MUNICH, Germany | November 28, 2007 | MediGene AG and Celltrion, Inc. signed a binding Memorandum of Understanding for the co-development and commercialization of an anti-L1 monoclonal antibody (“L1 MAb”) for the treatment of cancer in humans covering major cancer indications. Under the terms of the agreement, the companies will share responsibilities for development and commercialization of the L1 MAb. Celltrion will conduct process development and manufacturing of the product and will have exclusive responsibility for development and commercialization of the L1 MAb in Asia, including Japan. Celltrion will also have an option for global manufacturing rights to supply Phase III and commercial material. MediGene retains the rights for the development and commercialization of the product in Europe, USA and the remaining areas.

MediGene previously entered into an option and license agreement with The German Cancer Research Center (Deutsches Krebsforschungszentrum, “DKFZ”) and initiated the development of a monoclonal antibody against the tumor marker L1. During the period of cooperation MediGene will have the right to exercise an option to acquire an exclusive worldwide license on the application of the anti-L1 monoclonal antibody in anti-tumor therapy.

“MediGene and Celltrion have a shared vision for the development and commercialization of the L1 MAb in a range of potential cancer indications, with the lead indication being ovarian cancer,” said Peter Heinrich, Ph.D., Chief Executive Officer of MediGene. “We are confident in the potential of this product as a novel means of treating cancer in humans – an area where there is still a high unmet medical need. Celltrion as one of the leading biopharmaceutical manufacturing companies worldwide will be an excellent partner for this highly innovative drug candidate.”

“We are pleased to establish this alliance with MediGene, a company with a strong expertise in the development of cancer drugs,” said Jung-Jin Seo, Chairman and Chief Executive Officer of Celltrion. “This alliance will serve as a stepping stone to strengthen our business partnerships in the biopharmaceutical industry and to build a marketing and sales organization at Celltrion. MediGene shares our enthusiasm and commitment to developing this first-in-class molecule and to bring the L1 MAb more quickly to patients.”

About L1: The L1 protein highly specifically occurs on the cell surfaces of malignant ovarian and endometrial tumors (ovarian and uterine cancer), whereas it is not found in the respective healthy tissue or benign tumors. For this reason, this protein is especially suited as a new tumor marker in diagnostics and therapy.
