Mechanism Of Action:
Vandetanib is a selective and potent inhibitor of VEGFR (vascular endothelial growth factor receptor), EGFR (epidermal growth factor receptor) and RET (RE-arranged during Transfection) tyrosine kinases.
EGFR- and VEGFR-dependent signaling are both clinically validated pathways in cancer, including non-small-cell lung cancer. RET activity is important in some types of thyroid cancer, and early data with vandetanib in medullary thyroid cancer led to orphan-drug designation by the regulatory authorities in the USA and EU.
Indication:
It indicated for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease.
- Use in patients with indolent, asymptomatic or slowly progressing disease only after careful consideration of the treatment related risks.
