Vandetanib

Dosage Form: tablet

BOXED WARNING SECTION

WARNING: QT PROLONGATION, TORSADES DE POINTES, AND SUDDEN DEATH

Vandetanib can prolong the QT interval. Torsades de pointes and sudden death have been reported in patients receiving Vandetanib. Vandetanib should not be used in patients with hypocalcemia, hypokalemia, hypomagnesemia, or long QT syndrome. Hypocalcemia, hypokalemia and/or hypomagnesemia must be corrected prior to Vandetanib administration and should be periodically monitored. Drugs known to prolong the QT interval should be avoided. If a drug known to prolong the QT interval must be administered, more frequent ECG monitoring is recommended. Given the half-life of 19 days, ECGs should be obtained to monitor the QT at baseline, at 2-4 weeks and 8-12 weeks after starting treatment with Vandetanib and every 3 months thereafter. Following any dose reduction for QT prolongation, or any dose interruptions greater than 2 weeks, QT assessment should be conducted as described above. Because of the 19-day half-life, adverse reactions including a prolonged QT interval may not resolve quickly. Monitor appropriately. Only prescribers and pharmacies certified through the Vandetanib REMS education program are able to prescribe and dispense Vandetanib [see Warnings and Precautions (5.15)].

1. INDICATIONS AND USAGE

. Medullary Thyroid Cancer (MTC)

Vandetanib is indicated for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease.

Use of Vandetanib in patients with indolent, asymptomatic or slowly progressing disease should be carefully considered because of the treatment related risks of Vandetanib.

2. DOSAGE AND ADMINISTRATION

The recommended daily dose is 300 mg of Vandetanib taken orally. Vandetanib treatment should be continued until patients are no longer benefiting from treatment or an unacceptable toxicity occurs.

Vandetanib may be taken with or without food.

If a patient misses a dose, the missed dose should not be taken if it is less than 12 hours before the next dose.

For Patients who have Difficulty Swallowing Solids

Vandetanib tablets should not be crushed. If Vandetanib tablets cannot be taken whole, the tablets can be dispersed in a glass containing 2 ounces of non-carbonated water and stirred for approximately 10 minutes until the tablet is dispersed (will not completely dissolve). No other liquids should be used. The dispersion should be swallowed immediately. To ensure the full dose is received, any residues in the glass should be mixed again with an additional 4 ounces of non-carbonated water and swallowed.

The dispersion can also be administered through nasogastric or gastrostomy tubes.

Direct contact of crushed tablets with the skin or mucous membranes should be avoided. If such contact occurs, wash thoroughly. Avoid exposure to crushed tablets.

Dosage Adjustment

In the event of corrected QT interval, Fridericia (QTcF) greater than 500 ms, interrupt dosing until QTcF returns to less than 450 ms, then resume at a reduced dose.

For CTCAE (Common Terminology Criteria for Adverse Events) grade 3 or greater toxicity, interrupt dosing until toxicity resolves or improves to CTCAE grade 1, and then resume at a reduced dose.

Because of the 19-day half-life, adverse reactions including a prolonged QT interval may not resolve quickly. Monitor appropriately [see Warnings and Precautions (5.1-5.7, 5.9)].

The 300-mg daily dose can be reduced to 200 mg (two 100-mg tablets) and then to 100 mg for CTCAE grade 3 or greater toxicities.

Elderly

No adjustment in starting dose is required for patients over 65 years of age. There are limited data for patients over the age of 75. [see Dosage and Administration (2.4)]

Concomitant Strong CYP3A4 Inducers

Avoid the concomitant use of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital). Patients should also avoid taking St. John’s Wort. [see Warnings and Precautions (5.11)and Drug Interactions (7.1)]

Patients With Renal Impairment

The starting dose should be reduced to 200 mg in patients with moderate (creatinine clearance ≥30 to <50 mL/min) and severe (creatinine clearance <30 mL/min) renal impairment. [see Warnings and Precautions (5.12)and Use in Specific Populations (8.6)]

Patients with Hepatic Impairment

Single dose pharmacokinetic data from volunteers with hepatic impairment receiving 800 mg suggest that there were no differences in pharmacokinetics compared to patients with normal hepatic function. There are limited data in patients with liver impairment (serum bilirubin greater than 1.5 times the upper limit of normal). Vandetanib is not recommended for use in patients with moderate (Child-Pugh B) and severe (Child-Pugh C) hepatic impairment, as safety and efficacy have not been established.

4. CONTRAINDICATIONS

Do not use in patients with congenital long QT syndrome [see Boxed Warning].

5. WARNINGS AND PRECAUTIONS

QT Prolongation and Torsades de Pointes

Vandetanib can prolong the QT interval in a concentration-dependent manner [see Clinical Pharmacology (12.4)]. Torsades de pointes, ventricular tachycardia and sudden deaths have been reported in patients administered Vandetanib.

Vandetanib treatment should not be started in patients whose QTcF interval is greater than 450 ms. Vandetanib should not be given to patients who have a history of Torsades de pointes, congenital long QT syndrome, bradyarrhythmias or uncompensated heart failure. Vandetanib has not been studied in patients with ventricular arrhythmias or recent myocardial infarction. Vandetanib exposure is increased in patients with impaired renal function. The starting dose should be reduced to 200 mg in patients with moderate to severe renal impairment and QT interval should be monitored closely.

An ECG and levels of serum potassium, calcium, magnesium and TSH should be obtained at baseline, at 2-4 weeks and 8-12 weeks after starting treatment with Vandetanib and every 3 months thereafter. Electrolytes and ECGs may require more frequent monitoring in case of diarrhea. Following any dose reduction for QT prolongation, or any dose interruptions greater than 2 weeks, QT assessments should be conducted as described above. Serum potassium levels should be maintained at 4 mEq/L or higher (within normal range) and serum magnesium and serum calcium should be kept within normal range to reduce the risk of electrocardiogram QT prolongation.

Avoid using Vandetanib with drugs known to prolong the electrocardiogram QT interval [see Warnings and Precautions (5.11) and Drug Interactions (7.3)]. If such drugs are given to patients already receiving Vandetanib and no alternative therapy exists, ECG monitoring of the QT interval should be performed more frequently.

Patients who develop a QTcF greater than 500 ms should stop taking Vandetanib until QTcF returns to less than 450 ms. Dosing of Vandetanib can be resumed at a reduced dose [see Dosage and Administration (2.1)].

Skin Reactions and Stevens-Johnson Syndrome

Severe skin reactions (including Stevens-Johnson syndrome), some leading to death, have been reported with Vandetanib. Treatment of severe skin reactions has included systemic corticosteroids and permanent discontinuation of Vandetanib. Mild to moderate skin reactions may manifest as rash, acne, dry skin, dermatitis, pruritis and other skin reactions (including photosensitivity reactions and palmar-plantar erythrodysesthesia syndrome). Mild to moderate skin reactions have been treated with topical and systemic corticosteroids, oral antihistamines, and topical and systemic antibiotics. If CTCAE grade 3 or greater skin reactions occur, Vandetanib treatment should be stopped until improved. Upon improvement, consideration should be given to continuing treatment at a reduced dose or permanent discontinuation of Vandetanib. [see Dosage and Administration (2.1)]

Photosensitivity reactions are increased with Vandetanib. Patients should be advised to wear sunscreen and protective clothing when exposed to the sun. Due to the long half-life of Vandetanib, protective clothing and sunscreen should continue for 4 months after discontinuation of treatment.

Interstitial Lung Disease

Interstitial Lung Disease (ILD) or pneumonitis has been observed with Vandetanib and deaths have been reported. Consider a diagnosis of ILD in patients presenting with non-specific respiratory signs and symptoms such as hypoxia, pleural effusion, cough, or dyspnea, and in whom infectious, neoplastic, and other causes have been excluded by means of appropriate investigations. Advise patients to report promptly any new or worsening respiratory symptoms.

Patients who develop radiological changes suggestive of ILD and have few or no symptoms may continue Vandetanib therapy with close monitoring at the discretion of the treating physician.

If symptoms are moderate, consider interrupting therapy until symptoms improve. The use of corticosteroids and antibiotics may be indicated.

For cases where symptoms of ILD are severe, discontinue Vandetanib therapy and the use of corticosteroids and antibiotics may be indicated until clinical symptoms resolve. Even upon resolution of severe ILD, permanent discontinuation of Vandetanib should be considered.

Ischemic Cerebrovascular Events

Ischemic cerebrovascular events have been observed with Vandetanib and some cases have been fatal. In the randomized medullary thyroid cancer (MTC) study, ischemic cerebrovascular events were observed more frequently with Vandetanib compared to placebo (1.3% compared to 0%) and no deaths were reported. The safety of resumption of Vandetanib therapy after resolution of an ischemic cerebrovascular event has not been studied. Discontinue Vandetanib in patients who experience a severe ischemic cerebrovascular event.

Hemorrhage

Serious hemorrhagic events, which in some cases were fatal, have been observed with Vandetanib. There were no fatal bleeding events in the randomized MTC study. Three patients died of fatal bleeding events while on Vandetanib therapy in clinical studies. Do not administer Vandetanib to patients with recent history of hemoptysis of ≥ 1/2 teaspoon of red blood. Discontinue Vandetanib in patients with severe hemorrhage.

Heart Failure

Heart failure has been observed with Vandetanib and some cases have been fatal. Discontinuation of Vandetanib may be necessary in patients with heart failure. Heart failure may not be reversible upon stopping Vandetanib. Monitor for signs and symptoms of heart failure.

Diarrhea

Diarrhea was observed in patients who received Vandetanib. Routine anti-diarrheal agents are recommended. Diarrhea may cause electrolyte imbalances. Since QT prolongation is seen with Vandetanib, serum electrolytes and ECGs should be carefully monitored in patients with diarrhea. [see Warnings and Precautions (5.1)] If severe diarrhea develops, Vandetanib treatment should be stopped until diarrhea improves. Upon improvement, treatment with Vandetanib should be resumed at a reduced dose [see Dosage and Administration (2.1)].

Hypothyroidism

In the randomized MTC study where 90% of the patients enrolled had prior thyroidectomy, increases in the dose of the thyroid replacement therapy were required in 49% of the patients randomized to Vandetanib compared to 17% of the patients randomized to placebo. Thyroid-stimulating hormone (TSH) should be obtained at baseline, at 2 to 4 weeks and 8 to 12 weeks after starting treatment with Vandetanib and every 3 months thereafter. If signs or symptoms of hypothyroidism occur, thyroid hormone levels should be examined and thyroid replacement therapy should be adjusted accordingly.

Hypertension

Hypertension, including hypertensive crisis, has been observed with Vandetanib. All patients should be monitored for hypertension and it should be controlled as appropriate. Dose reduction or interruption may be necessary. If high blood pressure cannot be controlled, Vandetanib should not be restarted [see Dosage and Administration (2.1)].

Reversible posterior leukoencephalopathy syndrome

Reversible posterior leukoencephalopathy syndrome (RPLS), a syndrome of subcortical vasogenic edema diagnosed by an MRI of the brain, has been observed with Vandetanib. This syndrome should be considered in any patient presenting with seizures, headache, visual disturbances, confusion or altered mental function. In clinical studies, three of four patients who developed RPLS while taking Vandetanib, including one pediatric patient, also had hypertension. Discontinuation of Vandetanib treatment in patients with RPLS should be considered.

Drug Interactions

The administration of Vandetanib with agents that are strong CYP3A4 inducers should be avoided [see Dosage and Administration (2.3)and Drug Interactions (7.1)].

The administration of Vandetanib with anti-arrhythmic drugs (including, but not limited to amiodarone, disopyramide, procainamide, sotalol, dofetilide) and other drugs that may prolong the QT interval (including but not limited to cloroquine, clarithromycin, dolasetron, granisetron, haloperidol, methadone, moxifloxacin, and pimozide) should be avoided [see Drug Interactions (7.3)].

Renal Impairment

Vandetanib exposure is increased in patients with impaired renal function. The starting dose should be reduced to 200 mg in patients with moderate to severe renal impairment and QT interval should be monitored closely. There is no information available for patients with end-stage renal disease requiring dialysis. [see Boxed Warning, Dosage and Administration (2.4)and Use in Specific Populations (8.6)]

Hepatic Impairment

Vandetanib is not recommended for use in patients with moderate and severe hepatic impairment, as safety and efficacy have not been established. [see Dosage and Administration (2.5)]

Use in Pregnancy

Vandetanib can cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies in pregnant women using Vandetanib. In nonclinical studies in rats, Vandetanib was embryotoxic, fetotoxic, and teratogenic, at exposures equivalent to or lower than those expected at the recommended human dose of 300 mg/day. As expected from its pharmacological actions, Vandetanib has shown significant effects on all stages of female reproduction in rats.

If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant during treatment with Vandetanib. Women should be advised that they must use effective contraception to prevent pregnancy during treatment and for at least four months following the last dose of Vandetanib [see Use in Specific Populations (8.1)].

Vandetanib REMS (Risk Evaluation and Mitigation Strategy) Program

Because of the risk of QT prolongation, Torsades de pointes, and sudden death, Vandetanib is available only through a restricted distribution program called Vandetanib REMS Program. Only prescribers and pharmacies certified with the program are able to prescribe and dispense Vandetanib.

An overview of the requirements for prescribers and pharmacies is included below.

  • To be certified, prescribers must review the educational materials, agree to comply with the REMS requirements and enroll in the program.
  • To be certified, pharmacies that dispense Vandetanib must enroll in the program, train their pharmacy staff to verify that each prescription is written by a certified prescriber before dispensing to a patient, and agree to comply with the REMS requirements.

To learn about the specific REMS requirements and to enroll in the Vandetanib REMS Program call 1-800-236-9933 or visit www.Vandetanibrems.com.

6. ADVERSE REACTIONS

The most commonly reported adverse drug reactions (>20%) have been diarrhea, rash, acne, nausea, hypertension, headache, fatigue, decreased appetite, and abdominal pain. The most common laboratory abnormalities (>20%) were decreased calcium, increased ALT, and decreased glucose [see Dosage and Administration (2.1)and Warnings and Precautions (5.2, 5.3 and 5.9)].

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

. Clinical Studies Experience

Patients with unresectable locally advanced or metastatic medullary thyroid cancer were treated with Vandetanib 300 mg (n=231) or Placebo (n= 99). Patients with investigator-determined progression or patients who continued treatment after the data cut-off could receive open label Vandetanib. The following adverse reactions have been reported.

Adverse reactions resulting in death in patients receiving Vandetanib (N=5) were respiratory failure, respiratory arrest, aspiration pneumonia, cardiac failure with arrhythmia, and sepsis. Adverse reactions resulting in death in patients receiving placebo were gastrointestinal hemorrhage (1%) and gastroenteritis (1%). In addition there was one sudden death and one death from cardiopulmonary arrest, in patients receiving Vandetanib after data cut-off. Causes of discontinuation in Vandetanib-treated patients in >1 patient included asthenia, fatigue, rash, arthralgia, diarrhea, hypertension, prolonged QT interval, increase in creatinine and pyrexia. Serious adverse events in Vandetanib-treated patients in >2% of patients included diarrhea, pneumonia, and hypertension. Clinically important uncommon adverse drug reactions in patients who received Vandetanib versus patients who received placebo included pancreatitis (0.4% vs. 0%) and heart failure (0.9% vs. 0%). In the integrated summary of safety database, the most common cause of death in patients who received Vandetanib was pneumonia.

The incidence of Grade 1-2 bleeding events was 14% in patients receiving Vandetanib compared with 7% on placebo in the randomized portion of the medullary thyroid cancer (MTC) study. The incidence was similar in the 300 mg monotherapy safety program with a 13% incidence.

Blurred vision was more common in patients who received Vandetanib versus patients who received placebo for medullary thyroid cancer (9% vs. 1%, respectively). Scheduled slit lamp examinations have revealed corneal opacities (vortex keratopathies) in treated patients, which can lead to halos and decreased visual acuity. It is unknown if this will improve after discontinuation. Ophthalmologic examination, including slit lamp, is recommended in patients who report visual changes. If a patient has blurred vision, do not drive or operate machinery.

Table 2 provides the frequency and severity of laboratory abnormalities reported for patients with medullary thyroid cancer receiving randomized treatment with Vandetanib or placebo.

Alanine aminotransferase elevations occurred in 51% of patients on Vandetanib in the randomized medullary thyroid cancer (MTC) study. Grade 3-4 ALT elevations were seen in 2% of patients and no patients had a concomitant increase in bilirubin. Elevations in ALT have resulted in temporary discontinuation of Vandetanib. However, 16 of 22 patients with a grade 2 elevation in ALT continued 300 mg Vandetanib. Seven patients who continued Vandetanib had a normal ALT within 6 months. In the protocol, ALT was monitored every 3 months and more frequently as indicated.

7. DRUG INTERACTIONS

CYP3A4 Inducers

Drugs that are CYP3A4 inducers can alter Vandetanib plasma concentrations. The concomitant use of known strong CYP3A4 inducers should be avoided while receiving Vandetanib therapy. St. John’s Wort may decrease Vandetanib exposure unpredictably and should be avoided [see Dosage and Administration (2.3)and Warnings and Precautions (5.11)].

CYP3A4 Inhibitors

In healthy subjects, no clinically significant interaction was shown between Vandetanib and the potent CYP3A4 inhibitor, itraconazole.

Drugs that Prolong the QT Interval

The administration of Vandetanib with agents that may prolong the QT interval should be avoided [see Warnings and Precautions (5.11)].

8. USE IN SPECIFIC POPULATIONS

. Pregnancy

Pregnancy Category D[see Warnings and Precautions (5.14)].

Vandetanib can cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies of Vandetanib in pregnant women. Vandetanib is embryotoxic, fetotoxic, and teratogenic to rats, at exposures equivalent to or lower than those expected at the recommended human dose of 300 mg/day. When Vandetanib was administered to female rats prior to mating and through the first week of pregnancy, there were increases in pre-implantation loss and post-implantation loss resulting in a significant reduction in the number of live embryos. This dose administered to rats during organogenesis, caused an increase in post-implantation loss including embryofetal death. Vandetanib caused total litter loss when administered at a dose of 25 mg/kg/day during organogenesis until expected parturition. When administered during organogenesis, Vandetanib doses of 1, 10 and 25 mg/kg/day (approximately 0.03, 0.4, and 1.0 times respectively, the Cmax in patients with cancer at the recommended human dose) caused malformations of the heart vessels and delayed ossification of the skull, vertebrae and sternum, indicating delayed fetal development. A no effect level for these malformations was not identified in this study. In a rat pre- and post-natal development study, at doses producing maternal toxicity (1 and 10 mg/kg/day) during gestation and/or lactation, Vandetanib, decreased pup survival, and/or reduced post-natal pup growth. Reduced post-natal pup growth was associated with a delay in physical development.

If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid pregnancy while taking Vandetanib and for at least four months following the last dose of Vandetanib.

. Nursing Mothers

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. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Vandetanib, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

. Pediatric Use

Safety and efficacy of Vandetanib in pediatric patients have not been established.

. Geriatric Use

In total, 18% of medullary thyroid cancer patients treated with Vandetanib were age 65 years or older, and 3% were 75 years and older. No overall differences in safety and efficacy were observed between elderly and younger patients. No adjustment in starting dose is required for patients over 65 years of age. There are limited data for patients over the age of 75 years.

Renal Impairment

The pharmacokinetics of Vandetanib were evaluated after a single dose of 800 mg in subjects with mild (n = 6), moderate (n = 8), and severe (n = 6) renal impairment and normal (n = 10) renal function. Subjects with mild renal impairment had comparable mean AUC and clearance values to those with normal renal function. In subjects with moderate and severe renal impairment, the average AUC of Vandetanib increased by 39% and 41%, respectively, compared to patients with normal renal function.

The starting dose should be reduced to 200 mg in patients with moderate and severe renal impairment [see Dosage and Administration (2.4)and Warning and Precautions (5.12)].

Hepatic Impairment

The pharmacokinetics of Vandetanib were evaluated after a single dose of 800 mg in subjects with mild (n = 8), moderate (n = 7), and severe (n = 6) hepatic impairment and normal hepatic function (n = 5). Subjects with mild (Child-Pugh class A), moderate (Child-Pugh class B), and severe (Child-Pugh class C) hepatic impairment had comparable mean AUC and clearance values to those with normal hepatic function.

There are limited data in patients with liver impairment (serum bilirubin greater than 1.5 times the upper limit of normal). Vandetanib is not recommended for use in patients with moderate and severe hepatic impairment, as safety and efficacy have not been established. [see Dosage and Administration (2.5)and Warnings and Precautions (5.13)].

10. OVERDOSAGE

There is no specific treatment in the event of overdose with Vandetanib and possible symptoms of overdose have not been established. Because of the 19-day half-life, adverse reactions may not resolve quickly. In phase 1 clinical trials, a limited number of patients were treated with daily doses of up to 600 mg and healthy volunteers with daily doses up to 1200 mg. An increase in the frequency and severity of some adverse reactions, like rash, diarrhea and hypertension, was observed at multiple doses at and above 300 mg in healthy volunteer studies and in patients. In addition the possibility of QTc prolongation and Torsades de pointes should be considered.

Adverse reactions associated with overdose are to be treated symptomatically; in particular, severe diarrhea must be managed appropriately. In the event of an overdose, further doses of Vandetanib must be interrupted, and appropriate measures taken to assure that an adverse event has not occurred, i.e., ECG within 24 hours to determine QTc prolongation [see Dosage and Administration (2.1)].

11. DESCRIPTION

Vandetanib tablets for daily oral administration are available in two dosage strengths, 100 mg and 300 mg, containing 100 mg and 300 mg of Vandetanib, respectively. The tablet cores contain the following inactive ingredients: Tablet core: calcium hydrogen phosphate dihydrate, microcrystalline cellulose, crospovidone, povidone, and magnesium stearate. The tablet film-coat contains the following inactive ingredients: hypromellose 2910, macrogol 300, and titanium dioxide E171.

Vandetanib is chemically described as N-(4-bromo-2-fluorophenyl)-6-methoxy-7-[(1-methylpiperidin-4-yl) methoxy]quinazolin-4-amine.

The structural and molecular formulas are:

C22H24BrFN4O2

Vandetanib has a molecular weight of 475.36. Vandetanib exhibits pH-dependent solubility, with increased solubility at lower pH. Vandetanib is practically insoluble in water with a value of 0.008 mg/mL at 25°C (77°F ).

12. CLINICAL PHARMACOLOGY

. Mechanism of Action

Vandetanib is a tyrosine kinase inhibitor. In vitro studies have shown that Vandetanib inhibits the activity of tyrosine kinases including members of the epidermal growth factor receptor (EGFR) family, vascular endothelial cell growth factor (VEGF) receptors, rearranged during transfection (RET), protein tyrosine kinase 6 (BRK), TIE2, members of the EPH receptors kinase family, and members of the Src family of tyrosine kinases. Vandetanib inhibits endothelial cell migration, proliferation, survival and new blood vessel formation in in vitro models of angiogenesis. Vandetanib inhibits EGFR-dependent cell survival in vitro. In addition, Vandetanib inhibits 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 vivo Vandetanib administration reduced tumor cell-induced angiogenesis, tumor vessel permeability, and inhibited tumor growth and metastasis in mouse models of cancer.

There is no evidence of a relationship between RET mutations and efficacy with Vandetanib.

. Pharmacokinetics

A population pharmacokinetic analysis of Vandetanib was conducted in 231 patients with MTC following oral administration of 300 mg daily doses. The pharmacokinetics of Vandetanib at the 300 mg dose in MTC patients are characterized by a mean clearance of approximately 13.2 L/h, a mean volume of distribution of approximately 7450 L, and a median plasma half-life of 19 days.

Absorption

Following oral administration of Vandetanib, absorption is slow with peak plasma concentrations typically achieved at a median of 6 hours, range 4-10 hours, after dosing. Vandetanib accumulates approximately 8-fold on multiple dosing with steady state achieved from approximately 3 months.

Exposure to Vandetanib is unaffected by food.

Distribution

Vandetanib binds to human serum albumin and α1-acid-glycoprotein with in vitro protein binding being approximately 90%. In ex vivo plasma samples from colorectal cancer patients at steady state exposure after 300 mg once daily, the mean percentage protein binding was 93.7% (range 92.2 to 95.7%).

Metabolism

Following oral dosing of 14C-Vandetanib, unchanged vandentanib and metabolites Vandetanib N-oxide and N-desmethyl Vandetanib were detected in plasma, urine and feces. A glucuronide conjugate was seen as a minor metabolite in excreta only. N-desmethyl-Vandetanib is primarily produced by CYP3A4 and Vandetanib-N-oxide by flavin–containing monooxygenase enzymes FMO1 and FMO3. N-desmethyl-Vandetanib and Vandetanib-N-oxide circulate at concentrations of approximately 7-17.1% and 1.4-2.2%, respectively, of those of Vandetanib.

Excretion

Within a 21-day collection period after a single dose of 14C-Vandetanib, approximately 69% was recovered with 44% in feces and 25% in urine. Excretion of the dose was slow and further excretion beyond 21 days would be expected based on the plasma half-life.

Vandetanib was not a substrate of hOCT2 expressed in HEK293 cells. Vandetanib inhibits the uptake of the selective OCT2 marker substrate 14C-creatinine by HEK-OCT2 cells, with a mean IC50 of approximately 2.1 μg/mL. This is higher than Vandetanib plasma concentrations (approximately 0.81 μg/mL) observed after multiple dosing at 300 mg. Inhibition of renal excretion of creatinine by Vandetanib provides an explanation for increases in plasma creatinine seen in human subjects receiving Vandetanib.

Special Populations

Effects of Age and Gender

In a population pharmacokinetic evaluation in cancer patients, no relationship was apparent between oral clearance and patient age or gender.

Ethnicity

Based on a cross-study comparison in a limited number of patients, Japanese (N=3) and Chinese (N=7) patients had on average exposures that were higher than Caucasian (N=7) patients receiving the same dose.

Pediatric

The pharmacokinetics of Vandetanib have not been evaluated in pediatric patients.

QT Prolongation

In 231 medullary thyroid cancer patients randomized to receive Vandetanib 300 mg once daily in the phase 3 clinical trial, Vandetanib was associated with sustained plasma concentration-dependent QT prolongation. Based on the exposure-response relationship, the mean (90% CI) QTcF change from baseline (ΔQTcF) was 35 (33-36) ms for the 300-mg dose. The ΔQTcF remained above 30 ms for the duration of the trial (up to 2 years). In addition, 36% of patients experienced greater than 60 ms increase in ΔQTcF and 4.3% of patients had QTcF greater than 500 ms. Cases of Torsades de pointes and sudden death have been reported [see Warnings and Precautions (5.1, 5.11)].

13. NONCLINICAL TOXICOLOGY

. Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been conducted with Vandetanib.

Vandetanib was not mutagenic in vitro in the bacterial reverse mutation (Ames) assay and was not clastogenic in both the in vitro cytogenetic assay using human lymphocytes or in the in vivo rat micronucleus assay.

Based on nonclinical findings, male and female fertility may be impaired by treatment with Vandetanib. In a fertility study in male rats, Vandetanib had no effect on copulation or fertility rate when undosed females were mated with males administered 1, 5, or 20 mg/kg/day of Vandetanib (approximately 0.03, 0.22, or 0.40 times, respectively, the AUC in patients with cancer at the recommended human dose of 300 mg/day). There was a slight decrease in the number of live embryos at 20 mg/kg/day and an increase in preimplantation loss at >5 mg/kg/day. In a female fertility study, there was a trend towards increased estrus cycle irregularity, a slight reduction in pregnancy incidence and an increase in implantation loss. In a repeat-dose toxicity study in rats, there was a decrease in the number of corpora lutea in the ovaries of rats administered 75 mg/kg/day Vandetanib (approximately 1.8 times the AUC in patients with cancer at the recommended human dose) for 1 month.

. Animal Pharmacology and/or Toxicology

In an animal model of wound-healing, mice dosed with Vandetanib had reduced skin-breaking strength compared with controls. This suggests that Vandetanib slows but does not prevent wound healing. The appropriate interval between discontinuation of Vandetanib and subsequent elective surgery required to avoid the risks of impaired wound healing has not been determined.

Nodular masses were observed in a 6-month toxicology study in rats during treatment with ≥5 mg/kg/day Vandetanib (approximately 0.22 or 0.40 times, respectively, the AUC in patients with cancer at the recommended human dose of 300 mg/day). Masses were palpable during clinical assessments as early as week 13, were observed in multiple organs, and were associated with hemorrhagic or inflammatory findings.

14. CLINICAL STUDIES

A double-blind, placebo-controlled study randomized patients with unresectable locally advanced or metastatic medullary thyroid cancer to Vandetanib 300 mg (n=231) versus Placebo (n=100).

The primary objective was demonstration of improvement in progression-free survival (PFS) with Vandetanib compared to placebo. Other endpoints included evaluation of overall survival and overall objective response rate (ORR). Centralized, independent blinded review of the imaging data was used in the assessment of PFS and ORR. Upon objective disease progression based on the investigator’s assessment, patients were discontinued from blinded study treatment and given the option to receive open-label Vandetanib. Nineteen percent (44/231) of the patients initially randomized to Vandetanib opted to receive open-label Vandetanib after disease progression, and 58% (58/100) of the patients initially randomized to placebo opted to receive open-label Vandetanib after disease progression.

The result of the PFS analysis, based on the central review RECIST assessment, showed a statistically significant improvement in PFS for patients randomized to Vandetanib (Hazard Ratio (HR) = 0.35; 95% Confidence Interval (CI) = 0.24-0.53; p<0.0001). Analyses in the subgroups of patients who were symptomatic or had progressed within 6 months prior to their enrollment showed similar PFS results (HR = 0.31 95% CI: 0.19, 0.53 for symptomatic patients; HR = 0.41 95% CI: 0.25, 0.66 for patients who had progressed within 6 months prior to enrollment).

At the time of the primary analysis of PFS, 15% of the patients had died and there was no significant difference in overall survival between the two treatment groups. The overall objective response rate (ORR) for patients randomized to Vandetanib was 44% compared to 1% for patients randomized to placebo. All objective responses were partial responses.

17.8 Medication Guide

MEDICATION GUIDE

Vandetanib [van-DEH-tuh-nib]

Tablets

Read this Medication Guide before you start taking Vandetanib and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or treatment.

What is the most important information I should know about Vandetanib?

Vandetanib can cause a change in the electrical activity of your heart called QT prolongation, which can cause irregular heartbeats and that may lead to death. You should not take Vandetanib if you have had a condition called long QT syndrome since birth.

Your healthcare provider should perform tests to check the levels of your blood potassium, calcium, magnesium, and thyroid-stimulating hormone (TSH) as well as the electrical activity of your heart with a test called an electrocardiogram (ECG). You should have these tests:

  • Before starting Vandetanib

  • Regularly during Vandetanib treatment:

  • 2 to 4 weeks after starting Vandetanib

  • 8 to 12 weeks after starting Vandetanib

  • Every 3 months thereafter

  • If your healthcare provider changes your dose of Vandetanib

  • If you start taking medicine that causes QT prolongation

  • As instructed by your healthcare provider

Your healthcare provider may stop your Vandetanib treatment for a while and restart you at a lower dose if you have QT prolongation.

Call your healthcare provider right away if you feel faint, light-headed, or feel your heart beating irregularly while taking Vandetanib. These may be symptoms related to QT prolongation.

What is Vandetanib?

Vandetanib is a prescription medicine used to treat medullary thyroid cancer that cannot be removed by surgery or that has spread to other parts of the body. It takes a long time to get rid of Vandetanib from your body and you may be at risk for side effects related to Vandetanib after you have stopped your treatment.

It is not known if Vandetanib is safe and effective in children.

Who should not take Vandetanib?

Do not take Vandetanib if you have had QT prolongation.

What should I tell my healthcare provider before taking Vandetanib?

Before you take Vandetanib, tell your healthcare provider if you:

  • have any heart problems, including a condition called congenital long QT syndrome.

  • have an irregular heartbeat

  • take or have stopped taking a medicine that causes QT prolongation

  • have low blood levels of potassium, calcium, or magnesium

  • have high blood levels of thyroid-stimulating hormone

  • have high blood pressure

  • have skin problems

  • have a history of breathing problems

  • have a recent history of coughing up blood or bleeding

  • have diarrhea

  • have liver problems

  • have kidney problems

  • have seizures or are being treated for seizures

  • are pregnant or plan to become pregnant. Vandetanib can cause harm to your unborn baby. Talk to your healthcare provider if you are pregnant or plan to become pregnant.

    • If you are able to become pregnant, you should use effective birth control during your treatment with Vandetanib and for at least 4 months after your last dose of Vandetanib.

    • Talk to your healthcare provider about birth control methods to prevent pregnancy while you are taking Vandetanib.

  • are breastfeeding or plan to breastfeed. It is not known if Vandetanib passes into your breast milk. You and your healthcare provider should decide if you will take Vandetanib or breastfeed. You should not do both.

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Vandetanib and other medicines may affect each other causing side effects.

Especially tell your healthcare provider if you take:

  • St. John’s Wort. You should not take St. John’s Wort while taking Vandetanib.

  • certain medicines that can affect how your liver breaks down medicine

  • a medicine for your heart

Ask your healthcare provider if you are not sure if your medicine is one listed above.

Do not take other medicines while taking Vandetanib until you have talked with your healthcare provider or pharmacist.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

How should I take Vandetanib?

  • Take Vandetanib exactly as your healthcare provider tells you to take it. Do not change your dose or stop taking Vandetanib unless your healthcare provider tells you to.

  • Vandetanib may be taken with or without food.

  • Swallow Vandetanib tablets whole with water.

  • Do not crush or chew Vandetanib tablets. If Vandetanib tablets are accidentally crushed, contact with skin should be avoided. If contact occurs, wash affected areas well with water.

  • If you cannot swallow Vandetanib tablets whole:

    • place your dose of Vandetanib in a glass that contains 2 ounces of noncarbonated water (no other liquids should be used).

    • stir the Vandetanib tablet(s) and water mixture for about 10 minutes or until the tablet(s) are in very small pieces (the tablets will not completely dissolve).

    • swallow Vandetanib and water mixture right away.

    • if any Vandetanib and water mixture remains in the glass, mix with an additional 4 ounces of noncarbonated water and swallow the mixture to make sure that you take your full dose of Vandetanib.

  • If you miss a dose and your next dose is in:

    • less than 12 hours, take your next dose at the normal time. Do not make up for the missed dose.

    • 12 hours or more, take the missed dose as soon as you remember. Take the next dose at the normal time.

Call your healthcare provider right away if you take too much Vandetanib.

  • During treatment with Vandetanib, your healthcare provider should check your blood and heart for side effects. See “What is the most important information I should know about Vandetanib?”
