Adecatumumab (MT201) is a recombinant human IgG1 monoclonal antibody which is used to target tumor cells. It binds to the epithelial cell adhesion molecule (EpCAM - CD326), with the intent to trigger antibody-dependent cellular cytotoxicity. It was developed by Micromet Inc, which was acquired by Amgen.[1]

Adecatumumab has been used in clinical studies of treatment in colorectal, prostate[2] and breast cancers.[3] Phase II results were published in 2010.[4]
