Eisai began its oncology research program in 1987, discovering several small molecules that are in development as chemotherapeutic agents. In addition to its in-house oncology research and development (R&D) program, Eisai made three strategic acquisitions to establish a solid business infrastructure and enter the U.S. oncology market.

In October 2006, Eisai acquired four products mainly for the treatment of cutaneous T-cell lymphoma, as well as an oncology specialty sales force, from Ligand Pharmaceuticals. This provided Eisai with an initial commercial infrastructure for oncology products. The acquisition of Morphotek, Inc. in April 2007 added important antibody technology and an antibody pipeline. In January 2008, Eisai acquired MGI PHARMA, INC., an oncology and acute care-focused company, to broaden its R&D and commercial capabilities, pipeline and product portfolio in oncology and supportive care.

Eisai is committed to addressing the unmet medical needs of patients with cancer and deliver novel treatment options that create hope with them.
