Amatuximab
Pronunciation
Definition 1
A chimeric IgG1 monoclonal antibody against human mesothelin with potential anti-tumor activity. Amatuximab specifically targets mesothelin, a cell surface glycoprotein involved in cell adhesion and overexpressed on many epithelial-derived cancer cells. Upon binding to the mesothelin antigen, amatuximab triggers an antibody dependent cellular cytotoxicity (ADCC)-mediated host immune response against mesothelin-expressing cells, resulting in cell lysis.

Definition 2
A monoclonal antibody being studied in the treatment of some types of cancer. Monoclonal antibodies are made in the laboratory and can locate and bind to substances in the body, including cancer cells. Anti-mesothelin monoclonal antibody MORAb-009 binds to mesothelin (a protein that is made by some cancer cells) and stops the cells from dividing. (NCI Dictionary)
