Oportuzumab monatox
DrugBank Accession Number
DB05319
Background

VB4-845 is studied in the treatment of certain types of head and neck cancer. VB4-845 is made by linking a monoclonal antibody fragment to a toxic protein that may kill cancer cells. VB4-845 is a fusion protein containing humanized scFv specific for the epithelial cell adhesion molecule, Ep-CAM, a tumor cell-associated target highly expressed on carcinoma cells of epithelial origin and a truncated portion of Pseudomonas exotoxin A.

Mechanism of action

VB4-845 binds to EpCAM (a protein on the surface of epithelial cells and some types of cancer cells). Also called anti-EpCAM-Pseudomonas-exotoxin fusion protein and Proxinium. It targets and kills Ep-CAM-positive tumors by apoptosis.
