Boxed warning. HEPATOTOXICITY Severe and fatal hepatotoxicity has been observed in clinical trials. Monitor hepatic function and interrupt, reduce, or discontinue dosing as recommended. WARNING: HEPATOTOXICITY See full prescribing information for complete boxed warning. Severe and fatal hepatotoxicity has been observed in clinical trials. Hepatic Toxicity: Severe and fatal hepatotoxicity has occurred. Monitor liver tests at baseline, regularly during treatment and as clinically indicated. Withhold Pazopanib tablets and resume at reduced dose with continued weekly monitoring for 8 weeks, or permanently discontinue with weekly monitoring until resolution based on severity of hepatotoxicity. QT Prolongation and Torsades de Pointes: Monitor patients who are at significant risk of developing QT interval prolongation. Monitor electrocardiograms (ECGs) and electrolytes at baseline and as clinically indicated. Correct hypokalemia, hypomagnesemia, and hypocalcemia prior to initiating Pazopanib tablets and during treatment. Cardiac Dysfunction: Cardiac dysfunction, including decreased left ventricular ejection fraction (LVEF) and congestive heart failure, have occurred. Monitor blood pressure and manage as appropriate. Monitor for clinical signs or symptoms of congestive heart failure. Conduct baseline and periodic evaluation of LVEF in patients at risk of cardiac dysfunction. Withhold or permanently discontinue Pazopanib tablets based on severity of cardiac dysfunction. Hemorrhagic Events: Fatal hemorrhagic events have occurred. Pazopanib tablets have not been studied in patients who have a history of hemoptysis, cerebral hemorrhage, or clinically significant gastrointestinal hemorrhage in the past 6 months. Withhold Pazopanib tablets and resume at reduced dose or permanently discontinue based on severity of hemorrhagic events. Arterial Thromboembolic Events: Arterial thromboembolic events have been observed and can be fatal. Pazopanib tablets have not been studied in patients who have had an arterial thromboembolic event within the previous 6 months. Permanently discontinue Pazopanib tablets in case of an arterial thromboembolic event. Venous Thromboembolic Events: Venous thromboembolic events (VTEs) have been observed, including fatal pulmonary emboli (PE). Monitor for signs and symptoms of VTE and PE. Withhold Pazopanib tablets and then resume at same dose or permanently discontinue based on severity of VTE. Thrombotic Microangiopathy: Thrombotic microangiopathy (TMA), including thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS), has been observed.

The following clinically significant adverse reactions are elsewhere in the labeling: Hepatic Toxicity QT Prolongation and Torsades de Pointes Cardiac Dysfunction Hemorrhagic Events Arterial Thromboembolic Events Venous Thromboembolic Events Thrombotic Microangiopathy (TMA) Gastrointestinal Perforation and Fistula Interstitial Lung Disease (ILD)/Pneumonitis Posterior Reversible Encephalopathy Syndrome (PRES) Hypertension Hypothyroidism Proteinuria Tumor Lysis Syndrome Infection The most common adverse reactions in patients with RCC (≥ 20%) are diarrhea, hypertension, hair color changes (depigmentation), nausea, anorexia, and vomiting. The most common adverse reactions in patients with STS (≥ 20%) are fatigue, diarrhea, nausea, decreased weight, hypertension, decreased appetite, vomiting, tumor pain, hair color changes, musculoskeletal pain, headache, dysgeusia, dyspnea, and skin hypopigmentation. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described in the WARNINGS AND PRECAUTIONS section reflect exposure of 977 patients who received Pazopanib tablets as a single agent, including 586 Pazopanib-treated patients with RCC. With a median duration of treatment of 7.4 months (range, 0.1 to 27.6) in these 977 patients, the most common adverse reactions (≥ 20%) in these 586 patients were diarrhea, hypertension, hair color change, nausea, fatigue, anorexia, and vomiting. The data described in the WARNINGS AND PRECAUTIONS also reflects exposure of 382 patients with advanced soft tissue sarcoma who received Pazopanib tablets as a single agent, with a median duration of treatment of 3.6 months (range, 0 to 53). The most common adverse reactions (≥ 20%) in these 382 patients were fatigue, diarrhea, nausea, decreased weight, hypertension, decreased appetite, vomiting, tumor pain, hair color changes, musculoskeletal pain, headache, dysgeusia, dyspnea, and skin hypopigmentation. Renal Cell Carcinoma The safety of Pazopanib tablets was evaluated in 290 patients with RCC who participated in VEG105192, a randomized, double-blind, placebo-controlled trial. The median duration of treatment was 4.5 months (range, 0 to 24) for patients who received Pazopanib tablets. Abridged from the full prescribing information.
