NCIt definition : A humanized monoclonal antibody directed against the human insulin-like growth factor-1
receptor (IGF-1R/CD221) with potential antineoplastic activity. Veligrotug specifically
binds to and blocks membrane-bound IGF-1R, preventing the binding of the natural ligand
IGF-1 and the subsequent activation of PI3K/AKT signal transduction, which may result
in the induction of apoptosis and a decrease in cellular proliferation. Activation
of IGF-1R, a receptor tyrosine kinase of the insulin receptor superfamily overexpressed
by various cancer cell types, stimulates cell proliferation, promotes angiogenesis,
enables oncogenic transformation, and suppresses apoptosis.;
