5 Warnings and Precautions

5.1 Hepatotoxicity

Additions underlined

Monitor liver function tests (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and bilirubin) at baseline, during each cycle, and as clinically indicated. Interrupt SUTENT for Grade 3 hepatotoxicity until resolution to Grade less than or equal to1 or baseline, then resume SUTENT at a reduced dose.

Discontinue SUTENT in patients with Grade 4 hepatotoxicity, in patients without resolution of Grade 3 hepatotoxicity, in patients who subsequently experience severe changes in liver function tests and in patients who have other signs and symptoms of liver failure. Safety in patients with ALT or AST >2.5 x upper limit of normal (ULN) or with >5 x ULN and liver metastases has not been established.

5.10 Reversible Posterior Leukoencephalopathy Syndrome

Additions and/or revisions underlined

Reversible posterior leukoencephalopathy syndrome (RPLS) has been reported in <1% of patients, some of which were fatal. Patients can present with hypertension, headache, decreased alertness, altered mental functioning, and visual loss, including cortical blindness. Magnetic resonance imaging is necessary to confirm the diagnosis. Discontinue SUTENT in patients developing RPLS.

5.12 Hypoglycemia

Additions underlined

SUTENT can result in symptomatic hypoglycemia, which may lead to loss of consciousness, or require hospitalization. In the pooled safety population, hypoglycemia occurred in 2% of the patients treated with SUTENT. Hypoglycemia has occurred in clinical trials in 2% of the patients treated with SUTENT for advanced RCC (Study 3) and GIST (Study 1) (n=577) and in approximately 10% of the patients treated with SUTENT for pNET (Study 6) (n=83). For patients being treated with SUTENT for pNET, pre-existing abnormalities in glucose homeostasis were not present in all patients who experienced hypoglycemia.

5.13 Osteonecrosis of the Jaw

Additions underlined

The safety of resumption of SUTENT after resolution of osteonecrosis of the jaw has not been established.

5.4 Hypertension

Additions underlined

In the pooled safety population, 29% of patients experienced hypertension. Grade 3 hypertension was reported in 7% of patients, and Grade 4 hypertension was reported in 0.2%.

Monitor blood pressure at baseline and as clinically indicated. Initiate and/or adjust antihypertensive therapy as appropriate. In cases of Grade 3 hypertension, withhold SUTENT until resolution to Grade less than or equal to1 or baseline, then resume SUTENT at a reduced dose. Discontinue SUTENT in patients with who develop Grade 4 hypertension.

5.5 Hemorrhagic Events and Viscus Perforation

Additions underlined

Hemorrhagic events, some of which were fatal, have involved the gastrointestinal tract, respiratory tract, tumor, urinary tract, and brain. In the pooled safety population, 30% of patients experienced hemorrhagic events, including Grade 3 or 4 in 4.2% of patients. Epistaxis was the most common hemorrhagic event and gastrointestinal hemorrhage was the most common Grade greater than or equal to 3-5 event.

Include serial complete blood counts (CBCs) and physical examinations with the clinical assessment of hemorrhagic events. Interrupt SUTENT for Grade 3 or 4 hemorrhagic events until resolution to Grade less than or equal to1 or baseline, then resume SUTENT at a reduced dose.

Discontinue SUTENT in patients without resolution of Grade 3 or 4 hemorrhagic events.

5 Warnings and Precautions

5.10 Reversible Posterior Leukoencephalopathy Syndrome

(New subsection added)

Reversible posterior leukoencephalopathy syndrome (RPLS) has been reported in <1% of patients, some of which were fatal. Patients can present with hypertension, headache, decreased alertness, altered mental functioning, and visual loss, including cortical blindness. Magnetic resonance imaging is necessary to confirm the diagnosis. Withhold SUTENT until resolution. The safety of reinitiating SUTENT in patients with RPLS is unknown.

5.13 Osteonecrosis of the Jaw

(Additions underlined)

Osteonecrosis of the Jaw (ONJ) occurred in patients treated with SUTENT. Concomitant exposure to other risk factors, such as bisphosphonates or dental disease/invasive dental procedures, may increase the risk of ONJ. Perform an oral examination prior to initiation of SUTENT and periodically during SUTENT therapy. Advise patients regarding good oral hygiene practices. Withhold SUTENT treatment for at least 3 weeks prior to scheduled dental surgery or invasive dental procedures, if possible. Withhold SUTENT for development of ONJ until complete resolution.

5.14 Impaired Wound Healing

(Subsection revisd, additions underlined)

Impaired wound healing has been reported in patients who received SUTENT [see Adverse Reactions (6.2)].

Withhold SUTENT for at least 3 weeks prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of SUTENT after resolution of wound healing complications has not been established.

5.15 Embryo-Fetal Toxicity

(Additions underlined)

Administration of sunitinib to pregnant rats and rabbits during the period of organogenesis resulted in teratogenicity at approximately 5.5 and 0.3 times the combined systemic exposure [combined area under the curve (AUC) of sunitinib plus its active metabolite] in patients administered the recommended daily dose (RDD) of 50 mg, respectively.

5.7 Thrombotic Microangiopathy

(Additions underlined)

Thrombotic Microangiopathy (TMA), including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, sometimes leading to renal failure or a fatal outcome, occurred in clinical trials and in postmarketing experience of SUTENT as monotherapy and administered in combination with bevacizumab. SUTENT is not approved for use in combination with bevacizumab.

MEDICATION GUIDE

(Additions underlined)

Before taking SUTENT tell your healthcare provider about all of your medical conditions, including if you:

  • plan to have surgery or have had a recent surgery. You should stop taking SUTENT at least 3 weeks before planned surgery. See “What are the possible side effects of SUTENT?”

    What are possible side effects of SUTENT?

     SUTENT may cause serious side effects, including:

  • Abnormal changes in the brain (Reversible Posterior Leukoencephalopathy Syndrome [RPLS]). RPLS can cause a collection of symptoms including headache, confusion, and vision loss. Some people who have taken SUTENT have developed RPLS that can lead to death. Your healthcare provider may stop your treatment with SUTENT if you have signs and symptoms of RPLS.

  • Jaw-bone problems (osteonecrosis). Severe jaw bone problems have happened in some people who take SUTENT. Certain risk factors such as taking a bisphosphonate medicine or having dental disease may increase your risk of getting osteonecrosis. Your healthcare provider may tell you to see your dentist before you start taking SUTENT. Your healthcare provider may tell you to avoid dental procedures, if possible, during your treatment with SUTENT, especially if you are receiving a bisphosphonate medicine into a vein (intravenous). Tell your healthcare provider if you plan to have any dental procedures before or during treatment with SUTENT.

    • You should stop taking SUTENT at least 3 weeks before planned dental procedures.

    • Your healthcare provider should tell you when you may start taking SUTENT again after dental procedures.

       

  • Wound healing problems. Wound healing problems have happened in some people who take SUTENT. Tell your healthcare provider if you plan to have any surgery before or during treatment with SUTENT.

    • You should stop taking SUTENT at least 3 weeks before planned surgery.

    • Your healthcare provider should tell you when you may start taking SUTENT again after surgery.

5 Warnings and Precautions

5.2 Cardiovascular Events

(Additions and/or revisions are underlined)

Patients who presented with cardiac events within 12 months prior to SUTENT administration, such as myocardial infarction (including severe/unstable angina), coronary/peripheral artery bypass graft, symptomatic CHF, cerebrovascular accident or transient ischemic attack, or pulmonary embolism were excluded from SUTENT clinical studies. Patients with prior anthracycline use or cardiac radiation were also excluded from some studies. It is unknown whether patients with these concomitant conditions may be at a higher risk of developing drug-related left ventricular dysfunction.

7 Drug Interactions

7.1 Effect of Other Drugs on SUTENT

(Additions and/or revisions are underlined)

Strong CYP3A4 Inhibitors

Co-administration with strong CYP3A4 inhibitors may increase sunitinib plasma concentrations. Select an alternate concomitant medication with no or minimal enzyme inhibition potential. Consider a dose reduction for SUTENT when it is co-administered with strong CYP3A4 inhibitors.

Strong CYP3A4 Inducers

Co-administration with strong CYP3A4 inducers may decre ase sunitinib plasma concentrations. Select an alternate concomitant medication with no or minimal enzyme induction potential. Consider a dose increase for SUTENT when it must be co-administered with CYP3A4 inducers.

8 Use in Specific Populations

8.4 Pediatric Use

(Additions and/or revisions are underlined)

The safety and effectiveness of SUTENT in pediatric patients have not been established. Safety and pharmacokinetics  of sunitinib  were assessed in an open-label study (NCT00387920)  in pediatric patients 2 years to <17 years of age (n=29) with refractory solid tumors. In addition,  efficacy, safety and pharmacokinetics of sunitinib was assessed in another open-label study (NCT01462695)  in pediatric patients 2 years to <17 years of age (n=27) with high-grade glioma  or ependymoma. The maximum tolerated dose (MTD) normalized for body surface area (BSA) was lower in pediatric patients compared to adults. Sunitinib  was poorly tolerated in pediatric patients. The occurrence of dose-limiting  cardiotoxicity  prompted an amendment of the NCT00387920 study to exclude patients with previous exposure to anthracyclines or cardiac radiation. No responses were reported in patients in either of the trials.

Apparent clearance and volume of distribution  normalized for BSA for sunitinib  and its active major metabolite were lower in pediatrics as compared to adults.

The effect on open tibial growth plates in pediatric patients who received SUTENT has not been adequately studied. See Juvenile Animal Toxicity Data below.

Juve nile Animal Toxicity Data

Physeal dysplasia was observed in cynomolgus monkeys with open growth plates treated for greater than or equal to 3 months (3 month dosing 2, 6, 12 mg/kg/day; 8 cycles of dosing 0.3, 1.5, 6.0 mg/kg/day) with sunitinib at doses that were greater than 0.4 times the RDD based on systemic exposure (AUC)…

8.6 Hepatic Impairment

(Additions and/or revisions are underlined)

No starting dose adjustment is required in patients with mild or moderate (Child-Pugh Class A or B) hepatic impairment. SUTENT was not studied in patients with severe (Child-Pugh Class C) hepatic impairment.

8.7 Renal Impairme nt

(Additions and/or revisions are underlined)

No starting dose adjustment is recommended in patients with mild (CLcr 50 to 80 mL/min), moderate (CLcr 30 to <50 mL/min), or severe (CLcr <30 mL/min) renal impairment who are not on dialysis.

In patients with end-stage renal disease (ESRD) on hemodialysis, no starting dose adjustment is recommended. However, subsequent doses may be increased gradually up to 2-fold based on safety and tolerability

SUTENT can cause severe hepatotoxicity, resulting in liver failure or death. Liver failure occurred at an incidence of <1% in clinical trials... Monitor liver function tests (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and bilirubin) before initiation of treatment, during each cycle of treatment, and as clinically indicated…

Safety in patients with ALT or AST >2.5 x upper limit of normal (ULN) or, if due to liver metastases, >5.0 x ULN has not been established.

5.11 Hypoglycemia

(Additions and/or revisions are underlined)

SUTENT can result in symptomatic hypoglycemia, which may lead to loss of consciousness, or require hospitalization. Hypoglycemia has occurred in clinical trials in 2% of the patients treated with SUTENT for advanced RCC and GIST and in approximately 10% of the patients treated with SUTENT for pNET. In the adjuvant treatment of RCC study, no patients on SUTENT experienced hypoglycemia.

5.12 Osteonecrosis of the Jaw (ONJ)

(Additions and/or revisions are underlined)

Consider preventive dentistry prior to treatment with SUTENT. If possible, avoid invasive dental procedures while on SUTENT treatment, particularly in patients receiving intravenous bisphosphonate therapy.

5.14 Embryo-Fetal Toxicity

(Subsection title has been revised; Additions and/or revisions are underlined)

Based on findings from animal studies and its mechanism of action, SUTENT can cause fetal harm when administered to pregnant woman. Administration of sunitinib to pregnant rats and rabbits during the period of organogenesis resulted in teratogenicity at approximately 5.5 and 0.3 times the clinical systemic exposure (AUC) at the recommended daily doses (RDD) of 50 mg/day, respectively.

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with SUTENT and for 4 weeks following the final dose.

5.2 Cardiovascular Events

(Additions and/or revisions are underlined)

Discontinue SUTENT in the presence of clinical manifestations of congestive heart failure (CHF). Interrupt SUTENT and/or reduce the dose in patients without clinical evidence of CHF who have an ejection fraction of >20% but <50% below baseline or below the lower limit of normal if baseline ejection fraction is not obtained.

In patients without cardiac risk factors a baseline evaluation of ejection fraction should be considered. Carefully monitor patients for clinical signs and symptoms of CHF while receiving SUTENT. Baseline and periodic evaluations of left ventricular ejection fraction (LVEF) should also be considered while these patients are receiving SUTENT.

Cardiovascular events, including heart failure, cardiomyopathy, myocardial ischemia, and myocardial infarction, some of which were fatal, have been reported.

In patients treated with SUTENT (N=7527) for GIST, advanced RCC, adjuvant treatment of RCC and pNET, 3% of patients experienced heart failure; 71% of the patients with heart failure were reported as recovered. Fatal cardiac failure was reported in <1% of patients.

In the adjuvant treatment of RCC study, 11 patients in each arm experienced a decreased ejection fraction meeting Grade 2 CTCAE criteria (LVEF 40-50% and a 10-19% decrease from baseline). No patients had a Grade 3-4 decrease in ejection fraction. The ejection fractions of three patients in the SUTENT arm and 2 patients in the placebo arm did not return to greater than or equal to 50% or baseline by the time of last measurement. No patients who received SUTENT were diagnosed with CHF.

5.3 QT Interval Prolongation and Torsade de Pointes

(Additions and/or revisions are underlined)

SUTENT can cause QT interval prolongation in a dose-dependent manner, which may lead to an increased risk for ventricular arrhythmias including Torsade de Pointes…

Monitor patients with a history of QT interval prolongation, patients who are taking antiarrhythmics, or patients with relevant pre-existing cardiac disease, bradycardia, or electrolyte disturbances…

5.4 Hypertension

(Additions and/or revisions are underlined)

Long-Term Safety in RCC

The long-term safety of SUTENT in patients with metastatic RCC was analyzed across 9 completed clinical studies conducted in the first-line, bevacizumab-refractory, and cytokine-refractory treatment settings. The analysis included 5739 patients, of whom 807 (14%) were treated for at least 2 years and 365 (6%) for at least 3 years. Prolonged treatment with SUTENT did not appear to be associated with new types of adverse reactions. There appeared to be no increase in the yearly incidence of adverse reactions at later time points.

Hypothyroidism increased during the second year of treatment with new cases reported up to year 4.

 

Adjuvant Treatment of RCC

The safety of SUTENT was evaluated in S-TRAC, a randomized, double-blind, placebo-controlled trial in which patients who had undergone nephrectomy for RCC received SUTENT 50 mg daily (n=306) on Schedule 4/2 or placebo (n=304). The median duration of treatment was 12.4 months (range: 0.13-14.9) for SUTENT and 12.4 months (range: 0.03-13.7) for placebo. Permanent discontinuation due to an adverse reaction occurred in 28% of patients on SUTENT and 6% on placebo. Adverse reactions leading to permanent discontinuation in >2% of patients include hand-foot syndrome and fatigue/asthenia. Dosing interruptions or delays occurred in 166 (54%) and 84 (28%) patients on SUTENT and placebo, respectively. One hundred forty patients (45.8%) out of 306 patients in the SUTENT arm and 15 patients (5%) out of 304 patients in the placebo arm had dose reductions.

Table 5 compares the incidence of common (greater than or equal to 10%) treatment-emergent adverse reactions for patients receiving SUTENT versus placebo.

Venous Thromboembolic Events

In patients treated with SUTENT (N=7527) for GIST, advanced RCC, adjuvant treatment of RCC and pNET, 3.5% of patients experienced a venous thromboembolic event; 2.2% Grade 3-4.

 

Pancreatic Function

Pancreatitis was observed in 5 patients (1%) receiving SUTENT for treatment-naïve RCC compared to 1 patient (<1%) receiving IFN-alpha. In a trial of patients receiving adjuvant treatment for RCC, 1 patient (<1%) on SUTENT and none on placebo experienced pancreatitis. Pancreatitis was observed in 1 patient (1%) receiving SUTENT for pNET and 1 patient (1%) receiving placebo.

8 Use in Specific Populations

8.1 Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; additions and/or revisions are underlined)

Risk Summary

Based on animal reproduction studies and its mechanism of action, SUTENT can cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform a drug-associated risk. In animal developmental and reproductive toxicology studies, oral administration of sunitinib to pregnant rats and rabbits throughout organogenesis resulted in teratogenicity (embryolethality, craniofacial and skeletal malformations) at 5.5 and 0.3 times the AUC in patients administered the recommended daily doses (RDD), respectively. Advise pregnant women or females of reproductive potential of the potential hazard to a fetus.

The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the estimated background risk in the United States (U.S.) general population of major birth defects is 2%-4% and of miscarriage is 15%-20% of clinically recognized pregnancies.

 

Data

Animal Data

In a female fertility and early embryonic development study, female rats were administered oral sunitinib (0.5, 1.5, 5 mg/kg/day) for 21 days prior to mating and for 7 days after mating. Embryolethality was observed at 5 mg/kg/day (approximately 5 times the AUC in patients administered the RDD of 50 mg/day).

In embryo-fetal developmental toxicity studies, oral sunitinib was administered to pregnant rats (0.3, 1.5, 3, 5 mg/kg/day) and rabbits (0.5, 1, 5, 20 mg/kg/day) during the period of organogenesis. In rats, embryolethality and skeletal malformations of the ribs and vertebrae were observed at the dose of 5 mg/kg/day (approximately 5.5 times the systemic exposure [combined AUC of sunitinib + primary active metabolite] in patients administered the RDD). No adverse fetal effects were observed in rats at doses less than or equal to 3 mg/kg/day (approximately 2 times the AUC in patients administered the RDD). In rabbits, embryolethality was observed at 5 mg/kg/day (approximately 3 times the AUC in patients administered the RDD), and craniofacial malformations (cleft lip and cleft palate) were observed at greater than or equal to 1 mg/kg/day (approximately 0.3 times the AUC in patients administered the RDD of 50 mg/day).

Sunitinib (0.3, 1, 3 mg/kg/day) was evaluated in a pre- and postnatal development study in pregnant rats. Maternal body weight gains were reduced during gestation and lactation at doses ?1 mg/kg/day (approximately 0.5 times the AUC in patients administered the RDD). At 3 mg/kg/day (approximately 2 times the AUC in patients administered the RDD), reduced neonate body weights were observed at birth and persisted in the offspring of both sexes during the preweaning period and in males during postweaning period. No adverse developmental effects were observed at doses less than or equal to 1 mg/kg/day.

8.2 Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; additions and/or revisions are underlined)

There is no information regarding the presence of sunitinib and its metabolites in human milk. Sunitinib and its metabolites were excreted in rat milk at concentrations up to 12-fold higher than in plasma. Because of the potential for serious adverse reactions in breastfed infants from SUTENT, advise a lactating woman not to breastfeed during treatment with SUTENT and for at least 4 weeks after the last dose.
