Adecatumumab

Adecatumumab (MT201) is a recombinant human monoclonal antibody of the IgG1 subclass with a binding specificity to epithelial cell adhesion molecule (EpCAM). EpCAM (CD326) is a cell surface protein that is frequently expressed at high level on most solid tumor types, including prostate, breast, colon, gastric, ovarian, pancreatic and lung cancer. Overexpression of EpCAM has been shown to promote the proliferation, migration and invasiveness of breast cancer cells. Moreover, expression of EpCAM is associated with decreased survival in a number of cancer indications, including breast, gall bladder, bile duct, ovarian and ampullary pancreatic cancer. EpCAM has recently been shown to be expressed on cancer stem cells from breast, prostate, colon and pancreatic cancer. Clinical studies have shown a favorable safety profile and that clinical activity depends on the EpCAM target expression.
