Mechanism of actionIMC-A12 is a fully human monoclonal antibody that specifically targets the type 1 human insulin-like growth factor receptor (IGF-IR). Tumors have receptors for the insulin-like growth factor-1 (IGF-I), and it is thought that the presence of these receptors cause tumors to grow. IMC-A12 attaches to the receptors and may inhibit the growth of cancer cells.

Pharmacological action
General Function:
Protein tyrosine kinase activity
Specific Function:
Receptor tyrosine kinase which mediates actions of insulin-like growth factor 1 (IGF1). Binds IGF1 with high affinity and IGF2 and insulin (INS) with a lower affinity. The activated IGF1R is involved in cell growth and survival control. IGF1R is crucial for tumor transformation and survival of malignant cell. Ligand binding activates the receptor kinase, leading to receptor autophosphorylation,...
