Abbott and Eisai Announce Changes in the Sales Scheme in Japan for Adalimumab, A Fully Human Monoclonal Anti-TNF- Antibody
Abbott Japan Co., Ltd.
Eisai Co., Ltd.
Eisai Co., Ltd., (Headquarters in Tokyo, President: Haruo Naito), Abbott Japan Co., Ltd., (Pharmaceutical Products Group in Osaka, President: Glenn S. Warner), and Abbott Biotechnology Ltd., (Director and President: Thomas C. Freyman) concluded changes to the sales scheme for adalimumab, a fully human monoclonal antibody on January 24. With these changes, Eisai and Abbott have finalized the basic agreement concerning co-development and marketing for adalimumab in Japan. The following changes were made:
Adalimumab is the only fully-human monoclonal antibody for the treatment of autoimmune diseases, such as rheumatoid arthritis. Adalimumab works by neutralizing the activity of tumor necrosis factor (TNF-), a protein that plays a central role in inflammatory reactions in patients with autoimmune diseases. To date, adalimumab has been approved in 73 countries, and more than 250,000 people worldwide are currently being treated with adalimumab. In Europe and United States, adalimumab is distributed by Abbott. The distribution agreement in Japan follows the same model currently in place in Korea and Taiwan, where Abbott and Eisai also have agreements for development and distribution.
Eisai and Abbott Japan will make every effort to release adalimumab in Japan as soon as possible to improve patients QOL with intractable immunological/inflammatory diseases including rheumatoid arthritis, psoriasis, and Crohn's disease.

1. Summary of changes in the sales scheme for adalimumab
The tumor necrosis factors (TNFs) are a group of cytokines (i.e., substances mediating cell-cell interactions) mediating intercellular communication that have been found to damage tumor cells. TNF- is produced by many types of cells, including macrophages, lymphocytes, and vascular endothelial cells, and is known to cause and enhance inflammatory responses and to activate inflammatory cells.
2) Monoclonal antibody
A monoclonal antibody is a protein produced from clones of a single antibody-producing cell (called monoclone). Using the monoclonal antibody technique, manufacturers can obtain a homologous population of antibody molecules identical in amino acid sequence and other characteristics.
3) Eisai's Commitment to Immunology
Eisai, which is strong in low-molecular-weight drugs, is aggressively addressing biologics. In April 2007, Eisai acquired Morphotek, Inc., a bio-venture specialized in research and development of antibody drugs in the United States, and is now involved in creation of antibody drugs for the treatment of cancer, rheumatoid arthritis, and infections using Morphotek's unique technologies such as Human Morphodoma® and Libradoma™. In addition, Eisai is investigating immunotherapy for Alzheimer disease in cooperation with BioArctic Neuroscience Inc. in Sweden, and is developing and marketing a humanized anti-human TNF monoclonal antibody for the treatment of immune/inflammatory diseases including rheumatoid arthritis in Japan in cooperation with Abbott Japan. Eisai is thus committed to improving the QOL of patients and their families by producing antibody drugs.
4) Abbott's Commitment to Immunology
Abbott is focused on the discovery and development of innovative treatments for immunologic diseases. The Abbott Bioresearch Center, founded in 1989 in Worcester, Mass., United States, is a world-class discovery and basic research facility committed to finding new treatments for immune-mediated diseases.
5) About Abbott
