Important safety information

Hepatotoxicity : Fatal liver failure has been observed. Monitor liver function tests at baseline, during each cycle, and as clinically indicated. Interrupt SUTENT for Grade 3 hepatotoxicity until resolution to Grade ≤1 or baseline and resume SUTENT at a reduced dose; discontinue if no resolution. Discontinue SUTENT in patients with Grade 4 hepatoxicity, in patients who have subsequent severe changes in liver function tests or other signs and symptoms of liver failure. ( 2.4 , 5.1 ) • Cardiovascular Events : Myocardial ischemia, myocardial infarction, heart failure, cardiomyopathy, and decreased left ventricular ejection fraction (LVEF) to below the lower limit of normal including death have occurred. Monitor for signs and symptoms of congestive heart failure and consider monitoring LVEF at baseline and periodically during treatment. Discontinue SUTENT for clinical manifestations of congestive heart failure. Interrupt and/or dose reduce for decreased LVEF. ( 5.2 ) • QT Interval Prolongation and Torsade de Pointes : Monitor patients at higher risk for developing QT interval prolongation. Consider monitoring of electrocardiograms and electrolytes. ( 5.3 ) • Hypertension : Monitor blood pressure at baseline and as clinically indicated. Initiate and/or adjust antihypertensive therapy as appropriate. Interrupt SUTENT for Grade 3 hypertension until resolution to Grade ≤1 or baseline, then resume SUTENT at a reduced dose. Discontinue SUTENT in patients who develop Grade 4 hypertension. ( 5.4 ) • Hemorrhagic Events : Tumor-related hemorrhage and viscus perforation (both with fatal events) have occurred. Perform serial complete blood counts and physical examinations. Interrupt SUTENT for Grade 3 or 4 hemorrhagic events until resolution to Grade ≤1 or baseline, then resume at a reduced dose; discontinue if no resolution. ( 5.5 ) • Tumor Lysis Syndrome (TLS) : TLS (some fatal) has been reported primarily in patients with RCC and GIST. Monitor these patients and treat as clinically indicated. ( 5.6 ) • Thrombotic microangiopathy (TMA) : TMA, including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, sometimes leading to renal failure or a fatal outcome, has been reported. Discontinue SUTENT for TMA. ( 5.7 ) • Proteinuria : Renal failure or a fatal outcome has occurred. Monitor urine protein. Interrupt treatment for 24-hour urine protein of 3 or more grams. Discontinue for repeat episodes of 24-hour urine protein of 3 or more grams despite dose reductions or nephrotic syndrome. ( 5.8 ) • Dermatologic Toxicities : Necrotizing fasciitis, erythema multiforme, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) (some fatal) have occurred. Discontinue SUTENT for these events. ( 5.9 ) • Reversible Posterior Leukoencephalopathy Syndrome (RPLS) : RPLS (some fatal) has been reported. Monitor for signs and symptoms of RPLS. Withhold SUTENT until resolution. ( 5.10 ) • Thyroid Dysfunction : Monitor thyroid function at baseline, periodically during treatment, and as clinically indicated. Initiate and/or adjust therapy for thyroid dysfunction as appropriate. ( 5.11 ) • Hypoglycemia : Check blood glucose levels regularly and assess if antidiabetic drug dose modifications are required. ( 5.12 ) • Osteonecrosis of the Jaw (ONJ) : Withhold SUTENT for at least 3 weeks prior to invasive dental procedure and for development of ONJ until complete resolution. ( 5.13 ) • Impaired Wound Healing : 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. ( 5.14 ) • Embryo-Fetal Toxicity : Can cause fetal harm. Advise patients of potential risk to a fetus and to use effective contraception. ( 5.15 , 8.1 , 8.3 ) 5.1 Hepatotoxicity SUTENT can cause severe hepatotoxicity, resulting in liver failure or death. In the pooled safety population, liver failure occurred in <1% of patients in clinical trials. Liver failure include jaundiced, elevated transaminases and/or hyperbilirubinemia in conjunction with encephalopathy, coagulopathy, and/or renal failure. 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 ≤1 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 × upper limit of normal (ULN) or with >5 × ULN and liver metastases has not been established. 5.2 Cardiovascular Events Cardiovascular events, including heart failure, cardiomyopathy, myocardial ischemia, and myocardial infarction, some of which were fatal, have been reported. In pooled safety population, 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 experienced Grade 2 decreased ejection fraction (left ventricular ejection fraction [LVEF] 40% to 50% and a 10% to 19% decrease from baseline). In 3 of these 11 patients, the ejection fractions arm did not return to ≥50% or baseline by the time of last measurement. No patients who received SUTENT were diagnosed with CHF. 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 left ventricular dysfunction. Consider monitoring LVEF at baseline and periodically as clinically indicated. Carefully monitor patients for clinical signs and symptoms of congestive heart failure (CHF). Discontinue SUTENT in patients who experience clinical manifestations of CHF. Interrupt SUTENT and/or reduce the dose in patients without clinical evidence of CHF who have an ejection fraction of greater than 20% but less than 50% below baseline or below the lower limit of normal if baseline ejection fraction was not obtained. 5.3 QT Interval Prolongation and Torsade de Pointes 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. Torsade de Pointes was observed in <0.1% of patients. Monitor patients who are at higher risk of developing QT interval prolongation, including 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. Consider periodic monitoring of electrocardiograms and electrolytes (i.e., magnesium, potassium) during treatment with SUTENT. Monitor QT interval more frequently when SUTENT is concomitantly administered with strong CYP3A4 inhibitors or drugs known to prolong QT interval. Consider dose reducing SUTENT [see Dosage and Administration (2.5) , Drug Interactions (7.2) ] . 5.4 Hypertension 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…
