This medication is used to treat thyroid cancer (medullary type) that cannot be removed by surgery or that has spread to other parts of the body. It works by slowing or stopping the growth of cancer cells. Caprelsa (Vandetanib) belongs to a class of drugs known as tyrosine kinase inhibitors.
Mechanism of action:
ZD-6474 is a potent and selective inhibitor of VEGFR (vascular endothelial growth factor receptor), EGFR (epidermal growth factor receptor) and RET (REarranged during Transfection) tyrosine kinases. VEGFR- and EGFR-dependent signalling are both clinically validated pathways in cancer, including non-small-cell lung cancer (NSCLC). RET activity is important in some types of thyroid cancer, and early data with Caprelsa (Vandetanib) in medullary thyroid cancer has led to orphan-drug designation by the regulatory authorities in the USA and EU.
