Cixutumumab (IMC-A12) is a human monoclonal antibody for the treatment of solid tumors.
This drug was developed by ImClone Systems, since acquired by Eli Lilly, using phage display technology from Dyax.
It is 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 ligand IGF-1 and 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.
