Notes to Editors

Eisai in Oncology

Eisai is dedicated to discovering, developing and producing innovative oncology therapies that can make a difference and impact the lives of patients and their families. This passion for people is part of Eisai's human health care (hhc) mission, which strives for better understanding of the needs of patients and their families to increase the benefits health care provides. Our commitment to meaningful progress in oncology research, built on scientific expertise, is supported by a global capability to conduct discovery and preclinical research, and develop small molecules, therapeutic vaccines, and biologic and supportive care agents for cancer across multiple indications.

Halaven(R) (eribulin)

Eribulin is a non-taxane, microtubule dynamics inhibitor indicated for the treatment of patients with breast cancer who have previously received at least two chemotherapeutic regimens for metastatic disease and whose prior therapy should have included an anthracycline and a taxane.[1] Eribulin belongs to a class of antineoplastic agents, the halichondrins, which are natural products, isolated from the marine sponge Halichondria okadai. It is believed to work by inhibiting the growth phase of microtubule dynamics without affecting the shortening phase and sequesters tubulin into non-productive aggregates.

Lenvatinib (E7080)

Lenvatinib is an orally active inhibitor of multiple receptor tyrosine kinases (RTKs), including KDR (VEGFR-2), Flt-1 (VEGFR-1), FGFR1, PDGFR-beta and c-kit involved in angiogenesis and tumour proliferation.[2,3]

It is currently being investigated as a treatment for thyroid, hepatocellular, endometrial and other solid tumour types.

Farletuzumab (MORAb-003)

Farletuzumab is an investigational, humanized IgG1 monoclonal antibody targeting folate receptor alpha which is over-expressed on a number of epithelial-derived cancers, but largely absent in normal tissue. It is currently being developed as a potential treatment for ovarian and lung cancers. Significantly, farletuzumab has received orphan drug designation for ovarian cancer in the US, EU and Switzerland.

MORAb-004

MORAb-004 is an investigational humanized IgG1 monoclonal antibody that recognizes a cell surface protein, endosialin, also called Tumour Endothelial Marker-1 (TEM1) and CD248, which is expressed on tumour associated pericytes, tumour stromal cells and directly on a subset of malignant cells. Pericytes are specialised cells that support the formation of blood vessels that support blood to tumours for their growth and survival. Expression of endosialin in tumours has been observed by several independent laboratories and experiments, and blocking endosialin function has been shown to inhibit tumour growth and metastasis. MORAb-004 is currently being investigated as a monoclonal antibody for its potential treatment of many types of cancer. An Investigational New Drug <http://www.morphotek.com/pipeline/Definitions-(1).aspx> application was opened for MORAb-004 in 2009. MORAb-004 has received US FDA orphan drug designation <http://www.morphotek.com/pipeline/Definitions-(1).aspx> for sarcoma.

Amatuximab (MORAb-009)

Amatuximab (MORAb-009) is an investigational chimeric IgG1 antibody that targets a cell surface glycoprotein, mesothelin, which is over-expressed on a number of cancers. Mesothelin is thought to be involved in cell adhesion. Its presence is associated with a range of cancers, including pancreatic ductal adenocarcinoma, mesothelioma, epithelial ovarian cancer, and lung adenocarcinoma. Researchers at the National Cancer Institute (NCI) and the Johns Hopkins University have independently validated mesothelin as a potential target of immuno-based therapies. Amatuximab is currently being investigated clinically as a monoclonal antibody for its potential treatment of mesothelioma.
