Uses

Vandetanib is an antineoplastic kinase inhibitor used to treat symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease.

Vandetanib is currently approved as an alternative to local therapies for both unresectable and disseminated disease. Because Vandetanib can prolong the Q-T interval, it is contraindicated for use in patients with serious cardiac complications such as congenital long QT syndrome and uncompensated heart failure.

Vandetanib is also used to associated treatment for these conditions: Metastatic Medullary Thyroid Cancer, Locally advanced Medullary thyroid cancer

How Vandetanib works

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 vandetanib in medullary thyroid cancer has led to orphan-drug designation by the regulatory authorities in the USA and EU.

Food Interaction

Avoid grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum levels of vandetanib.
Avoid St. John's Wort. This herb induces CYP3A4 metabolism, which may reduce the serum levels of vandetanib.
Take with or without food.

Vandetanib Hypertension interaction

[Moderate] Hypertension, including hypertensive crisis, has occurred in patients treated with vandetanib.

Monitor all patients for hypertension and a dose reduction or interruption may be necessary.

If hypertension cannot be controlled, do not resume vandetanib.

Care should be taken when using this agent in hypertensive patients.

Close monitoring is recommended.
