IMC-11F8 is a fully human IgG1 monoclonal antibody that blocks the ligand binding site of EGFR that is involved in triggering and regulating the malignant growth of many EGFR-expressing epithelial tumors. IMC-11F8 is developed for the treatment of advanced colorectal cancer.
Investigated for use/treatment in colorectal cancer.
Mechanism of action
IMC-11F8 is a fully human monoclonal antibody that is designed to bind to the EGFR, thereby inhibiting certain ligands known as growth factors from binding to and activating the receptor. This action blocks a signal pathway key to tumor growth and repair and has also been shown to induce cell death, or apoptosis, in human tumors in animal models.

Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, amphiregulin, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homo- and/or heterodimerization and autophosphorylation on ke...
