A human monoclonal antibody directed against the insulin-like growth factor type I receptor (IGF1R) with potential antineoplastic activity. Figitumumab selectively binds to IGF1R, preventing insulin-like growth factor type 1 (IGF1) from binding to the receptor and subsequent receptor autophosphorylation. Inhibition of IGF1R autophosphorylation may result in a reduction in receptor expression on tumor cells that express IGF1R, a reduction in the anti-apoptotic effect of IGF, and inhibition of tumor growth. IGF1R is a receptor tyrosine kinase expressed on most tumor cells and is involved in mitogenesis, angiogenesis, and tumor cell survival. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
