Vandetanib; 443913-73-3; Zactima; ZD6474; Caprelsa; ZD 6474;

Vandetanib (INN, trade name Caprelsa) is an anti-cancer drug that is used for the treatment of certain tumours of the thyroid gland. It acts as a kinase inhibitor of a number of cell receptors, mainly the vascular endothelial growth factor receptor (VEGFR), theepidermal growth factor receptor (EGFR), and the RET-tyrosine kinase.[1][2] The drug was developed by AstraZeneca.

Approvals and indications

Vandetanib was the first drug to be approved by FDA (April 2011) for treatment of late-stage (metastatic) medullary thyroid cancer in adult patients who are ineligible for surgery.[3] Vandetanib was first initially marketed without a trade name,[4] and is being marketed under the trade name Caprelsa since August 2011.[5]

2011 年 4 月 6 by the FDA-approved surgical resection can not be used for locally advanced or metastatic medullary thyroid cancer (medullary thyroid cancer, MTC) of the drug. Vandetanib is vascular endothelial growth factor receptors (vascular endothelial growth factor receptor, VEGFR) and epidermal growth factor receptor (epidermal growth factor receptor, EGFR) antagonists, tyrosine kinase inhibitors (tyrosine kinase inhibitor). Produced by AstraZeneca.

The synthetic route is as follows:

Pharmacokinetics

Vandetanib is well absorbed from the gut, reaches peak blood plasma concentrations 4 to 10 hours after application, and has a half-life of 120 hours days on average, per Phase I pharmacokinetic studies. It has to be taken for about three months to achieve a steady-state concentration. In the blood, it is almost completely (90–96%) bound to plasma proteins such as albumin. It is metabolised to N-desmethylvandetanib via CYP3A4 and to vandetanib-N-oxide via FMO1 and 3. Both of these are active metabolites. Vandetanib is excreted via the faeces (44%) and the urine (25%) in form of the unchanged drug and the metabolites.[2][9][10]

Metabolites of vandetanib (top left): N-desmethylvandetanib (bottom left, via CYP3A4), vandetanib-N-oxide (bottom right, via FMO1 andFMO3), both pharmacologically active, and a minor amount of aglucuronide.[10]

Clinical trials

Non-small cell lung cancer

The drug underwent clinical trials as a potential targeted treatment for non-small-cell lung cancer. There have been some promising results from a phase III trial withdocetaxel.[11] There have also been ambivalent results when used with pemetrexed.[12] Another trial with docetaxel was recruiting in July 2009.[13]

AstraZeneca withdrew EU regulatory submissions for vandetanib (under the proposed trade name Zactima) in October 2009 after trials showed no benefit when the drug was administered alongside chemotherapy.[14]
