NCIt definition : A fully human IgG1 monoclonal antibody directed against the human insulin-like growth
factor-1 receptor (IGF-1R) with potential antineoplastic activity. Cixutumumab selectively
binds to membrane-bound IGF-1R, thereby preventing the binding of the natural ligand
IGF-1 and the subsequent activation of PI3K/AKT signaling pathway. Downregulation
of the PI3K/AKT survival pathway may result in the induction of cancer cell apoptosis
and may decrease cancer cellular proliferation. IGF-1R, a receptor tyrosine kinase
of the insulin receptor superfamily overexpressed by many cancer cell types, stimulates
cell proliferation, enables oncogenic transformation, and suppresses apoptosis; IGF-1R
signaling has been implicated in tumorigenesis and metastasis.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of some types of cancer. It
is a monoclonal antibody that is made in the laboratory and can bind to substances
in the body. Cixutumumab blocks the action of a protein needed for cell growth and
may kill cancer cells. It is a type of insulin-like growth factor-1 receptor (IGF-1R)
inhibitor.;
