IDENTIFICATION AND USE: Vandetanib is a white to off white powder that is formulated into film-coated tablets. Vandetanib is a multitargeted tyrosine kinase inhibitor used for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease. Because of the risk of QT prolongation, torsades de pointes, and sudden death, the US Food and Drug Administration (FDA) requires a Risk Evaluation and Mitigation Strategy (REMS) for vandetanib. Under the terms of the REMS program, vandetanib is available only under a restricted distribution program. It was granted orphan drug status by the FDA. HUMAN EXPOSURE AND TOXICITY: Vandetanib prolongs the QT interval in a concentration-dependent manner. Torsades de pointes (a distinctive polymorphic ventricular tachycardia in which the QRS amplitude varies and the QRS complexes appear to twist around), ventricular tachycardia, and sudden death have all been reported in patients receiving vandetanib. Vandetanib should not be used in patients who have a history of torsades de pointes, congenital long QT syndrome, bradyarrhythmias, or uncompensated heart failure, or in patients with electrolyte disturbances. Hypocalcemia, hypokalemia, and/or hypomagnesemia must be corrected prior to the administration of vandetanib. Other toxicities that are associated with the use of vandetanib and have resulted in fatalities include: severe skin reactions (including Stevens-Johnson syndrome), interstitial lung disease or pneumonitis, ischemic cerebrovascular events, serious hemorrhagic events and heart failure. Vandetanib may also cause fetal harm if administered to pregnant women. Pregnancy should therefore be avoided during vandetanib therapy. Vandetanib was not clastogenic to cultured human lymphocytes. ANIMAL STUDIES: In the rat, a single oral dose at 2000 mg/kg was not tolerated and all animals died or were killed for humane reasons by Day 4. Histopathological findings in these rats included hepatocyte vacuolation, fat deposition and necrosis in the liver, ulceration in the stomach, mucosal single cell necrosis and erosion in the duodenum, and macrophage vacuolation in the spleen. There were no adverse effects in rats dosed at 1000 mg/kg. A single oral dose of vandetanib at 2000 mg/kg to mice was not tolerated and all animals died or were killed for humane reasons on Day 1. A single oral dose of 1000 mg/kg resulted in the death of 1 out of 10 mice. There were no salient histopathology findings except for ulceration in the stomach in 1 animal dosed at 2000 mg/kg. In 1, 6 and 9 month studies, the dose limiting toxicities included gastrointestinal effects in dogs (including loose/abnormal feces, emesis and body weight loss), and skin toxicity and hepatotoxicity in rats. Vandetanib had no effect on copulation or fertility in male rats, while in female rats there was a trend towards increased estrus cycle irregularity, a slight reduction in pregnancy and an increase in post-implantation loss. In rats, vandetanib demonstrated the potential to cause embryo-fetal loss, delayed fetal development, heart vessel abnormalities and precocious ossification of some skull bones. In a rat pre- and post-natal development study, at doses producing maternal toxicity during gestation and/or lactation, vandetanib increased pre-birth loss and reduced post-natal pup growth. Vandetanib showed no mutagenic potential in 4 strains of Salmonella typhimurium (TA1535, TA1537, TA98 and TA100) and 2 strains of Escherichia coli (WP2P and WP2 uvrA) with or without metabolic activation.

In large clinical trials of vandetanib, abnormalities in routine liver tests were common with serum aminotransferase elevations, occurring in up to half of patients and rising above 5 times the upper limit of normal (ULN) 2% to 5% of patients. In prelicensure trials of vandetanib in thyroid cancer, there were no reports of clinically apparent liver injury with jaundice or hepatic failure. Since approval and more wide scale use, there have been no published reports of hepatotoxicity due to vandetanib and the product label does not include discussion of hepatotoxicity. However, many of the kinase inhibitors used in cancer chemotherapy have been implicated in cases of clinically apparent liver injury which typically arises within the first 2 to 12 weeks of therapy, presenting with symptoms of fatigue, nausea and jaundice and a hepatocellular pattern of serum enzyme elevations without immunoallergic or autoimmune features. Several tyrosine kinase inhibitors (imatinib, nilotinib) have also been implicated in causing reactivation of hepatitis B.

Concomitant use of vandetanib with drugs known to prolong the QT interval, including class Ia (e.g., disopyramide, procainamide, quinidine) and class III (e.g., amiodarone, sotalol, dofetilide) antiarrhythmic agents, some anti-infectives (e.g., clarithromycin, gatifloxacin, moxifloxacin), some antipsychotic agents (e.g., chlorpromazine, thioridazine, haloperidol, asenapine, olanzapine, paliperidone, pimozide, quetiapine, ziprasidone), some type 3 serotonin (5-HT3) receptor antagonists used as antiemetic agents (e.g., dolasetron, granisetron, ondansetron), chloroquine, methadone, and tetrabenazine should be avoided. If a drug known to prolong the QT interval must be administered, more frequent ECG monitoring is recommended. If a 5-HT3 receptor antagonist is clinically necessary, some clinicians prefer granisetron because its effects on ECG intervals are less pronounced than those observed with dolasetron or ondansetron.|Inducers of CYP3A4 can alter plasma vandetanib concentrations. Concomitant use of vandetanib with potent CYP3A4 inducers (e.g., carbamazepine, dexamethasone, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine) should be avoided. St. John's wort (Hypericum perforatum) may unpredictably decrease vandetanib exposure, and concomitant use of vandetanib with this agent also should be avoided.|Caprelsa increased plasma concentrations of digoxin. Use caution and closely monitor for toxicities when administering Caprelsa with digoxin.|Capresla increased plasma concentrations of metformin that is transported by the organic cation transporter type 2 (OCT2). Use caution and closely monitor for toxicities when administering Capresla with drugs that are transported by OCT2.

Vandetanib may cause fetal harm if administered to pregnant women; the drug has been shown to be embryotoxic, fetotoxic, and teratogenic in animals. Pregnancy should be avoided during therapy.|Vandetanib should not be initiated in patients with QT interval (corrected for heart rate using Fridericia's formula (QTcF) exceeding 450 msec. The drug should not be used in patients who have a history of torsades de pointes, congenital long QT syndrome, bradyarrhythmias, or uncompensated heart failure, or in patients with electrolyte disturbances; hypocalcemia, hypokalemia, and/or hypomagnesemia must be corrected prior to administration of vandetanib.

EXPERIMENTAL: ... A significant distribution of radioactivity was seen in milk of lactating rats and further on in the plasma of suckling pups.|EXPERIMENTAL: In nonclinical studies, vandetanib was excreted in rat milk and found in plasma of pups following dosing to lactating rats. Vandetanib transfer in breast milk resulted in relatively constant exposure in pups due to the long half-life of the drug.

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.|FDA Label|Caprelsa is indicated for the treatment of aggressive and symptomatic medullary thyroid cancer (MTC) in patients with unresectable locally advanced or metastatic disease.Caprelsa is indicated in adults, children and adolescents aged 5 years and older.For patients in whom re-arranged-during-transfection(RET) mutation is not known or is negative, a possible lower benefit should be taken into account before individual treatment decision.|Treatment of medullary thyroid carcinoma|Drug: Vandetanib

Vandetanib is a multi-kinase inhibitor that is used in the therapy of advanced or metastatic medullary thyroid cancer. Vandetanib therapy is commonly associated with transient elevations in serum aminotransferase during therapy, but has not been linked to cases of clinically apparent acute liver injury with jaundice.

Torsades de pointes, ventricular tachycardia, and sudden death have been reported in patients receiving vandetanib. In the phase 3 clinical study, patients randomized to receive vandetanib (300 once daily) had a mean increase in the QT interval (corrected for heart rate using Fridericia's formula (QTcF)) of 35 msec (range: 33-36 msec) from baseline; this increase in QTcF remained above 30 msec for the duration of the study (up to 2 years). In addition, an increase in QTcF of more than 60 msec from baseline occurred in 36% of patients receiving vandetanib, and QTcF exceeded 450 msec or 500 msec in 69 or 7% of patients, respectively.|Interstitial Lung Disease (ILD) or pneumonitis, including fatalities, has occurred in patients treated with Caprelsa.

Unchanged vandentanib and metabolites vandetanib N-oxide and N-desmethyl vandetanib were detected in plasma, urine and feces. N-desmethyl-vandetanib is primarily produced by CYP3A4, and vandetanib-N-oxide is primarily produced by flavin–containing monooxygenase enzymes FMO1 and FMO3.|The metabolism of vandetanib seemed to be similar in the toxicology species, rat and dog, as well as in mouse and human. The 2 major metabolites identified in excreta, were N-desmethyl-vandetanib and vandetanib-N-oxide. In mouse, a minor metabolite was also identified as O-desalkyl-vandetanib glucuronid. A glucuronide conjugate was also detected in human urine. Metabolism as well as biliary excretion appears to be most important for the elimination of vandetanib in preclinical species. CYP identification studies in vitro, suggest that CYP3A4 is involved in the formation of N-desmethyl-Vandetanib. vandetanib-N-oxide is formed via FMO1 and FMO3 (FMO=flavine mono-oxygenase). Both these enzymes are also found in kidney indicating that renal excretion might be contributed to the clearance of vandetanib.|Following oral dosing of (14)C-vandetanib, unchanged vandetanib and metabolites vandetanib N-oxide and N-desmethyl vandetanib were detected in plasma, urine and feces.

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.|In vitro, vandetanib inhibited epidermal growth factor (EGF)-stimulated receptor tyrosine kinase phosphorylation in tumor cells and endothelial cells and VEGF-stimulated tyrosine kinase phosphorylation in endothelial cells.|In vitro studies have shown that vandetanib inhibits the tyrosine kinase activity of the EGFR and VEGFR families, RET, BRK, TIE2, and members of the EPH receptor and Src kinase families. These receptor tyrosine kinases are involved in both normal cellular function and pathologic processes such as oncogenesis, metastasis, tumor angiogenesis, and maintenance of the tumor microenvironment. In addition, the N-desmethyl metabolite of the drug, representing 7 to 17.1% of vandetanib exposure, has similar inhibitory activity to the parent compound for VEGF receptors (KDR and Flt-1) and EGFR.|Oncogenic conversion of the RET /rearranged during transfection/ tyrosine kinase is a frequent feature of medullary thyroid carcinoma (MTC). Vandetanib is an ATP-competitive inhibitor of RET, epidermal growth factor receptor (EGFR), and vascular endothelial growth factor receptors kinases. In this study, vandetanib mechanism of action in TT and MZ-CRC-1 human MTC cell lines, carrying cysteine 634 to tryptophan (C634W) and methionine 918 to threonine (M918T) RET mutation respectively /were studied/. Vandetanib blunted MTC cell proliferation and RET, Shc and p44/p42 mitogen-activated protein kinase (MAPK) phosphorylation. Single receptor knockdown by RNA interference showed that MTC cells depended on RET for proliferation. Adoptive expression of the vandetanib-resistant V804M RET mutant rescued proliferation of TT cells under vandetanib treatment, showing that RET is a key vandetanib target in these MTC cells. Upon RET inhibition, adoptive stimulation of EGFR partially rescued TT cell proliferation, MAPK signaling, and expression of cell-cycle-related genes. This suggests that simultaneous inhibition of RET and EGFR by vandetanib may overcome the risk of MTC cells to escape from RET blockade through compensatory over-activation of EGFR.|Rearranged during transfection (RET) is widely expressed in neuroblastoma (NB) and partly contributes to high metastatic potential and survival of NB. The aim of the present study was to investigate whether vandetanib (a RET inhibitor) inhibits proliferation, migration and invasion of NB cells in vitro. The effects of vandetanib on the proliferation, apoptosis and cell cycle and on RET phosphorylation of SK-N-SH and SH-SY5Y cells were evaluated in vitro. The migration and invasion potential of vandetanib-treated NB cells were analyzed using Transwell cell migration and invasion assays, respectively. qPCR, western blotting and immunofluorescence were used to detect mRNA and protein levels in NB cells treated with vandetanib. Our data demonstrated that vandetanib inhibits the proliferation of SK-N-SH and SH-SY5Y cells and that this inhibition is mediated by the induction of G1 phase cell cycle arrest at lower concentrations and by apoptosis at higher concentrations. In the presence of vandetanib, the migration and invasion of two NB cell lines were markedly decreased compared with the control group (p<0.01). In addition, our data showed that the levels of C-X-C chemokine receptor type 4 (CXCR4) and matrix metalloproteinase 14 (MMP14) mRNA expression in NB cell lines treated with vandetanib were significantly lower than those in the cells that were treated with vehicle (p<0.01) and similar results were obtained for protein levels as determined by western blotting and immunofluorescence analysis. Vandetanib may inhibit the proliferation, migration and invasion of NB cells in vitro. The potential mechanisms for the inhibition of NB migration and invasion by vandetanib may partly be attributed to the ability of vandetanib to suppress the expression of CXCR4 and MMP14 in human NB cells.|For more Mechanism of Action (Complete) data for Vandetanib (6 total), please visit the HSDB record page.
