The data described in the WARNINGS AND PRECAUTIONS section reflect exposure of 977 patients who received pazopanib 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 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 was evaluated in 290 patients with RCC who participated in VEG105192, a randomized, double-blind, placebo-controlled trial [see Clinical Studies ( 14.1 )] . The median duration of treatment was 7.4 months (range, 0 to 23) for patients who received pazopanib. Forty-two percent of patients on pazopanib required a dose interruption and 36% required a dose reduction. Table 3 presents adverse reactions in VEG105192. Table 3.

Other Clinically Relevant Adverse Reactions Lipase Elevations In a single-arm RCC trial (VEG102616), elevated lipase was observed for 27% of 181 patients with available laboratory data. Elevated lipase as an adverse reaction was reported for 4% of 225 patients, including 2.7% (6/225) with Grade 3 and 0.4% (1/225) with Grade 4. In the RCC trials, clinical pancreatitis was observed in < 1% of 586 patients. Pneumothorax Two of 290 patients (0.7%) treated with pazopanib in the randomized RCC trial (VEG105192) and 8 of 240 patients (3.3%) treated with pazopanib in the randomized STS trial (VEG110727) developed a pneumothorax. Bradycardia In the randomized RCC trial (VEG105192), bradycardia based on vital signs (< 60 beats per minute) was observed in 19% of 280 patients treated with pazopanib. Bradycardia was reported as an adverse reaction in 2% of 290 patients. In the randomized STS trial (VEG110727), bradycardia based on vital signs (< 60 beats per minute) was observed in 19% of 238 patients treated with pazopanib. Bradycardia was reported as an adverse reaction in 2% of 240 patients. Adverse Reactions in East Asian Patients In an analysis of pooled clinical trial data (N = 1938) with pazopanib, Grade 3 and Grade 4 neutropenia (12% versus 2%), thrombocytopenia (6% versus < 1%) and palmar-plantar erythrodysesthesia (6% versus 2%) were observed more frequently in patients of East Asian descent than in patients of non-East Asian descent. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of pazopanib. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate the frequency or establish a causal relationship to drug exposure. Blood and Lymphatic System Disorders : Polycythemia Eye Disorders : Retinal detachment/tear Gastrointestinal Disorders : Pancreatitis Metabolic and Nutrition Disorder : Tumor lysis syndrome (including fatal cases) Vascular Disorders : Arterial (including aortic) aneurysms, dissections, and rupture (including fatal cases)

Dosage And Administration

2 DOSAGE AND ADMINISTRATION Recommended Dosage : 800 mg orally once daily without food (at least 1 hour before or 2 hours after a meal). ( 2.1 ) Moderate Hepatic Impairment : 200 mg orally once daily. ( 2.2 ) 2.1 Recommended Dosage The recommended dosage of pazopanib tablets is 800 mg (four 200 mg tablets) orally once daily without food (at least 1 hour before or 2 hours after a meal) until disease progression or unacceptable toxicity [see Clinical Pharmacology ( 12.3 )] . The dosage should be modified for hepatic impairment and in patients taking certain concomitant drugs [see Dosage and Administration ( 2.3 , 2.4 )] . Swallow tablets whole. Do not crush tablets due to the potential for increased rate of absorption, which may affect systemic exposure [see Clinical Pharmacology ( 12.3 )] . If a dose is missed, it should not be taken if it is < 12 hours until the next dose. 2.2 Dosage Modifications for Adverse Reactions Table 1 summarizes the recommended dose reductions. Table 1. Recommended Dose Reductions of Pazopanib Tablets for Adverse Reactions Dose Reduction For Renal Cell Carcinoma For Soft Tissue Sarcoma First 400 mg orally once daily 600 mg orally once daily Second 200 mg orally once daily 400 mg orally once daily Permanently discontinue pazopanib tablets in patients unable to tolerate the second dose reduction. Table 2 summarizes the recommended dosage modifications for adverse reactions. Table 2. Recommended Dosage Modifications of Pazopanib Tablets for Adverse Reactions Adverse Reaction Severity a Dosage Modification Hepatic Toxicity [see Warnings and Precautions ( 5.1 )] Isolated ALT elevations between 3 × ULN and 8 × ULN Continue and monitor liver function weekly until ALT returns to Grade 1 or baseline. Isolated ALT elevations of > 8 × ULN Withhold until improvement to Grade 1 or baseline. If the potential benefit for resuming treatment with pazopanib tablets is considered to outweigh the risk for hepatotoxicity, then resume at a reduced dose of no more than 400 mg once daily and measure serum liver tests weekly for 8 weeks. Permanently discontinue if ALT elevations > 3 × ULN recur despite dose reduction(s). ALT elevations > 3 × ULN occur concurrently with bilirubin elevations > 2 × ULN Permanently discontinue and continue to monitor until resolution.

Abbreviations: ALT, alanine aminotransferase; ULN, upper limit of normal. a National Cancer Institute Common Terminology Criteria for Adverse Events, version 5. 2.3 Dosage Modifications for Hepatic Impairment Moderate and Severe Hepatic Impairment In patients with moderate hepatic impairment [total bilirubin > 1.5 to 3 × upper limit of normal (ULN) and any alanine aminotransferase (ALT) value], consider alternatives to pazopanib tablets. If pazopanib tablets are used in patients with moderate hepatic impairment, reduce the pazopanib tablets dose to 200 mg orally once daily. Pazopanib tablets are not recommended in patients with severe hepatic impairment (total bilirubin > 3 × ULN and any ALT value) [see Use in Specific Populations ( 8.7 )] . 2.4 Dosage Modifications for Drug Interactions Strong CYP3A4 Inhibitors Avoid concomitant use of strong CYP3A4 inhibitors by use of an alternate concomitant medication with no or minimal potential to inhibit CYP3A4. If coadministration of a strong CYP3A4 inhibitor is warranted, reduce the dose of pazopanib tablets to 400 mg [see Drug Interactions ( 7.1 )] . Strong CYP3A4 Inducers Avoid concomitant use of strong CYP3A4 inducers by use of an alternate concomitant medication with no or minimal enzyme induction potential. Pazopanib tablets are not recommended in patients who cannot avoid chronic use of strong CYP3A4 inducers [see Drug Interactions ( 7.1 )] . Gastric Acid-Reducing Agents Avoid concomitant use of gastric acid-reducing agents. If concomitant use of a gastric acid-reducing agent cannot be avoided, consider short-acting antacid in place of proton pump inhibitors (PPIs) and H2-receptor antagonists. Separate short-acting antacid and pazopanib tablets dosing by several hours [see Drug Interactions ( 7.4 ), Clinical Pharmacology ( 12.3 )] .

Indications And Usage

1 INDICATIONS AND USAGE Pazopanib tablets are a kinase inhibitor indicated for the treatment of adults with: advanced renal cell carcinoma (RCC). ( 1.1 ) advanced soft tissue sarcoma (STS) who have received prior chemotherapy. ( 1.2 ) Limitations of Use : The efficacy of pazopanib tablets for the treatment of patients with adipocytic soft tissue sarcoma or gastrointestinal stromal tumors has not been demonstrated. 1.1 Renal Cell Carcinoma Pazopanib tablets are indicated for the treatment of adults with advanced renal cell carcinoma (RCC). 1.2 Soft Tissue Sarcoma Pazopanib tablets are indicated for the treatment of adults with advanced soft tissue sarcoma (STS) who have received prior chemotherapy. Limitations of Use : The efficacy of pazopanib tablets for the treatment of patients with adipocytic STS or gastrointestinal stromal tumors has not been demonstrated.

Overdosage

10 OVERDOSAGE Dose-limiting toxicity (Grade 3 fatigue) and Grade 3 hypertension were each observed in 1 of 3 patients dosed at 2,000 mg daily (2.5 times the recommended dose) and 1,000 mg daily (1.25 times the recommended dose), respectively. Provide general supportive measures to manage an overdose. Hemodialysis is not expected to enhance the elimination of pazopanib because pazopanib is not significantly renally excreted and is highly bound to plasma proteins.

Drug Interactions

7 DRUG INTERACTIONS Strong CYP3A4 Inhibitors : Avoid coadministration of pazopanib with strong CYP3A4 inhibitors. If coadministration cannot be avoided, reduce the dose of pazopanib. ( 2.4 , 7.1 ) Strong CYP3A4 Inducers : Consider an alternate concomitant medication with no or minimal enzyme induction potential. Pazopanib is not recommended if chronic use of strong CYP3A4 inducers cannot be avoided. ( 2.4 , 7.1 ) CYP Substrates : Coadministration of pazopanib with agents with narrow therapeutic windows that are metabolized by CYP3A4, CYP2D6, or CYP2C8 is not recommended. ( 7.2 ) Concomitant Use with Simvastatin : Concomitant use of pazopanib with simvastatin increases the risk of alanine aminotransferase (ALT) elevations. Increase to weekly monitoring of liver function as recommended. Withhold pazopanib and resume at reduced dose, or permanently discontinue based on severity of hepatotoxicity. ( 7.3 ) Concomitant Use With Gastric Acid-Reducing Agents : Avoid concomitant use of pazopanib with gastric acid-reducing agents. Consider short-acting antacids in place of proton pump inhibitors (PPIs) and H2-receptor antagonists. Separate antacid and pazopanib dosing by several hours. ( 2.4 , 7.4 ) 7.1 Effect of Other Drugs on Pazopanib Strong CYP3A4 Inhibitors Coadministration of pazopanib with strong inhibitors of CYP3A4 increases pazopanib concentrations [see Clinical Pharmacology ( 12.3 )] . Avoid coadministration of pazopanib with strong CYP3A4 inhibitors and consider an alternate concomitant medication with no or minimal enzyme inhibition potential. If coadministration of a strong CYP3A4 inhibitor cannot be avoided, reduce the dose of pazopanib [see Dosage and Administration ( 2.4 )] . Strong CYP3A4 Inducers Coadministration of strong CYP3A4 inducers may decrease plasma pazopanib concentrations. Consider an alternate concomitant medication with no or minimal enzyme induction potential. Pazopanib is not recommended if chronic use of strong CYP3A4 inducers cannot be avoided [see Dosage and Administration ( 2.4 )] . Transporters Coadministration of strong inhibitors of P-gp or BCRP may increase pazopanib concentrations. Avoid concomitant use of pazopanib with strong inhibitors of P-gp or BCRP. Consider selection of alternative concomitant medicinal products with no or minimal potential to inhibit P-gp or BCRP. 7.2 Effects of Pazopanib on Other Drugs CYP Substrates Coadministration of pazopanib with agents with narrow therapeutic windows that are metabolized by CYP3A4, CYP2D6, or CYP2C8 may result in inhibition of the metabolism of these products and create the potential for serious adverse reactions. The concomitant use of pazopanib with agents with narrow therapeutic windows that are metabolized by CYP3A4, CYP2D6, or CYP2C8 is not recommended [see Clinical Pharmacology ( 12.3 )] . 7.3 Concomitant Use with Simvastatin Concomitant use of pazopanib with simvastatin increases the incidence of ALT elevations. Across clinical trials of pazopanib as a single agent, ALT > 3 × ULN was reported in 126/895 (14%) of patients who did not use statins compared with 11/41 (27%) of patients who had concomitant use of simvastatin. If a patient receiving concomitant simvastatin develops ALT elevations, increase to weekly monitoring of liver function as recommended. Withhold pazopanib and resume at reduced dose, or permanently discontinue based on severity of hepatotoxicity [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 )] . Insufficient data are available to assess the risk of concomitant administration of alternative statins and pazopanib. 7.4 Concomitant Use with Gastric Acid-Reducing Agents Concomitant use of pazopanib with esomeprazole, a PPI, decreased the exposure of pazopanib. Avoid concomitant use of pazopanib with gastric acid-reducing agents. If concomitant administration with a gastric acid-reducing agent cannot be avoided, consider short-acting antacids in place of PPIs and H2-receptor antagonists. Separate short-acting antacid and pazopanib dosing by several hours to avoid a reduction in pazopanib exposure [see Dosage and Administration (2.4), Clinical Pharmacology ( 12.3 )] . 7.5 Drugs That Prolong the QT Interval Pazopanib is associated with QTc interval prolongation [see Warnings and Precautions ( 5.2 ), Clinical Pharmacology ( 12.2 )] . Avoid coadministration of pazopanib with drugs known to prolong the QT/QTc interval.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Pazopanib is a multi-tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-α and -β, fibroblast growth factor receptor (FGFR)-1 and -3, cytokine receptor (Kit), interleukin-2 receptor-inducible T-cell kinase (Itk), lymphocyte-specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor tyrosine kinase (c-Fms). In vitro , pazopanib inhibited ligand-induced autophosphorylation of VEGFR-2, Kit, and PDGFR-β receptors. In vivo , pazopanib inhibited VEGF-induced VEGFR-2 phosphorylation in mouse lungs, angiogenesis in a mouse model, and the growth of some human tumor xenografts in mice. 12.2 Pharmacodynamics Increases in blood pressure have been observed and are related to steady-state trough plasma pazopanib concentrations. Cardiac Electrophysiology The QT prolongation potential of pazopanib was assessed in a randomized, blinded, parallel trial (N = 96) using moxifloxacin as a positive control. Pazopanib 800 mg orally under fasting conditions was administered on Days 2 to 8 and 1,600 mg was administered on Day 9 after a meal in order to increase exposure to pazopanib and its metabolites. No large changes (i.e., > 20 msec) in QTc interval following exposure to pazopanib were detected in this QT trial. The trial was not able to exclude small changes (< 10 msec) in QTc interval, because assay sensitivity below this threshold (< 10 msec) was not established in this trial [see Warnings and Precautions ( 5.2 )] . 12.3 Pharmacokinetics The recommended dosage of 800 mg once daily results in mean AUC of 1,037 mcg•h/mL and C max of 58.1 mcg/mL. There was no consistent increase in AUC or C max at pazopanib doses above 800 mg. Administration of a single 400-mg crushed tablet increased AUC 0-72h by 46% and C max by approximately 2-fold and decreased T max by approximately 2 hours compared with administration of the whole tablet [see Dosage and Administration ( 2.1 )] . Absorption The median time to achieve peak concentrations was 2 to 4 hours after a dose. Effect of Food Systemic exposure to pazopanib is increased when administered with food. Administration of pazopanib with a high-fat (approximately 50% fat) or low-fat (approximately 5% fat) meal results in an approximately 2-fold increase in AUC and C max . Distribution Binding of pazopanib to human plasma protein in vivo was > 99% with no concentration dependence over the range of 10 to 100 mcg/mL. In vitro studies suggest that pazopanib is a substrate for P-gp and BCRP. Elimination Pazopanib has a mean half-life of 31 hours after administration of the recommended dose of 800 mg. Metabolism In vitro studies demonstrated that pazopanib is metabolized by CYP3A4 with a minor contribution from CYP1A2 and CYP2C8. Excretion Elimination is primarily via feces with renal elimination accounting for < 4% of the administered dose. Specific Populations Patients with Hepatic Impairment Table 7 presents a comparison of the median steady-state C max and the median AUC 0-24h values for patients with normal, mild, moderate and severe hepatic impairment. The median steady-state of pazopanib C max and AUC 0-24h after a once-daily dose of 800 mg in patients with mild impairment were in a similar range as the median steady-state C max and median AUC 0-24h in patients with no hepatic impairment. The maximum tolerated pazopanib dose in patients with moderate hepatic impairment was 200 mg once daily. The median steady-state C max and the median AUC 0-24h were approximately 43% and 29%, respectively, of the corresponding median values after administration of 800 mg once daily in patients with no hepatic impairment. The median steady-state C max and the median AUC 0-24h were approximately 18% and 15%, respectively, of the corresponding median values after administration of 800 mg once daily in patients with no hepatic impairment.

Drug Interactions Studies Clinical Studies Strong CYP3A4 Inhibitor: Coadministration of multiple doses of oral pazopanib 400 mg with multiple doses of oral ketoconazole 400 mg (strong CYP3A4/P-gp inhibitor) resulted in a 1.7-fold increase in the AUC 0-24h and a 1.5-fold increase in the C max of pazopanib [see Dosage and Administration ( 2.4 ), Drug Interactions ( 7. 1)] . Weak CYP3A4 Inhibitor: Coadministration of 1,500 mg lapatinib, a substrate and weak inhibitor of CYP3A4, P-gp, and BCRP, with pazopanib 800 mg resulted in an approximately 50% to 60% increase in mean pazopanib AUC 0-24h and C max . CYP1A2, CYP2C9 and CYP2C19 Substrates: Clinical studies, using pazopanib 800 mg once daily, have demonstrated that pazopanib does not have a clinically relevant effect on the pharmacokinetics of caffeine (CYP1A2 probe substrate), warfarin (CYP2C9 probe substrate), or omeprazole (CYP2C19 probe substrate) in patients with cancer. CYP3A4, CYP2D6, and CYP2C8 Substrates: Coadministration of pazopanib resulted in an increase of approximately 30% in the mean AUC and C max of midazolam (CYP3A4 probe substrate) and increases of 33% to 64% in the ratio of dextromethorphan to dextrorphan concentrations in the urine after oral administration of dextromethorphan (CYP2D6 probe substrate). Coadministration of pazopanib 800 mg once daily and paclitaxel 80 mg/m 2 (CYP3A4 and CYP2C8 substrate) once weekly resulted in a mean increase of 26% and 31% in paclitaxel AUC and C max , respectively [see Drug Interactions ( 7.2 )] . Gastric Acid-Reducing Agents: Coadministration of pazopanib with esomeprazole, a PPI, decreased the exposure of pazopanib by approximately 40% (AUC and C max ) [see Dosage and Administration ( 2.4 ), Drug Interactions ( 7.4 )] . In Vitro Studies In vitro studies with human liver microsomes showed that pazopanib inhibited the activities of CYP enzymes 1A2, 3A4, 2B6, 2C8, 2C9, 2C19, 2D6, and 2E1. Potential induction of human CYP3A4 was demonstrated in an in vitro human pregnane X receptor (PXR) assay. In vitro studies also showed that pazopanib inhibits UGT1A1 and organic anion-transporting polypeptide (OATP1B1) with IC 50 s of 1.2 and 0.79 µM, respectively. 12.5 Pharmacogenomics Pazopanib can increase serum total bilirubin levels [see Warnings and Precautions ( 5.1 )] . In vitro studies showed that pazopanib inhibits UGT1A1, which glucuronidates bilirubin for elimination. A pooled pharmacogenetic analysis of 236 white patients who received pazopanib showed that the (TA)7/(TA)7 genotype (UGT1A1*28/*28) (underlying genetic susceptibility to Gilbert’s syndrome) was associated with a statistically significant increase in the incidence of hyperbilirubinemia relative to the (TA)6/(TA)6 and (TA)6/(TA)7 genotypes. In a pooled pharmacogenetic analysis of data from 31 clinical studies of pazopanib administered as either monotherapy or in combination with other agents, ALT > 3 × ULN (Grade 2) occurred in 32% (42/133) of HLA-B*57:01 allele carriers and in 19% (397/2101) of non-carriers and ALT > 5 × ULN (Grade 3) occurred in 19% (25/133) of HLA-B*57:01 allele carriers and in 10% (213/2101) of non-carriers. In this dataset, 6% (133/2234) of the patients carried the HLA-B*57:01 allele [see Warnings and Precautions ( 5.1 )] .

Mechanism Of Action

12.1 Mechanism of Action Pazopanib is a multi-tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-α and -β, fibroblast growth factor receptor (FGFR)-1 and -3, cytokine receptor (Kit), interleukin-2 receptor-inducible T-cell kinase (Itk), lymphocyte-specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor tyrosine kinase (c-Fms). In vitro , pazopanib inhibited ligand-induced autophosphorylation of VEGFR-2, Kit, and PDGFR-β receptors. In vivo , pazopanib inhibited VEGF-induced VEGFR-2 phosphorylation in mouse lungs, angiogenesis in a mouse model, and the growth of some human tumor xenografts in mice.

Pharmacodynamics

12.2 Pharmacodynamics Increases in blood pressure have been observed and are related to steady-state trough plasma pazopanib concentrations. Cardiac Electrophysiology The QT prolongation potential of pazopanib was assessed in a randomized, blinded, parallel trial (N = 96) using moxifloxacin as a positive control. Pazopanib 800 mg orally under fasting conditions was administered on Days 2 to 8 and 1,600 mg was administered on Day 9 after a meal in order to increase exposure to pazopanib and its metabolites. No large changes (i.e., > 20 msec) in QTc interval following exposure to pazopanib were detected in this QT trial. The trial was not able to exclude small changes (< 10 msec) in QTc interval, because assay sensitivity below this threshold (< 10 msec) was not established in this trial [see Warnings and Precautions ( 5.2 )] .

Pharmacokinetics

12.3 Pharmacokinetics The recommended dosage of 800 mg once daily results in mean AUC of 1,037 mcg•h/mL and C max of 58.1 mcg/mL. There was no consistent increase in AUC or C max at pazopanib doses above 800 mg. Administration of a single 400-mg crushed tablet increased AUC 0-72h by 46% and C max by approximately 2-fold and decreased T max by approximately 2 hours compared with administration of the whole tablet [see Dosage and Administration ( 2.1 )] . Absorption The median time to achieve peak concentrations was 2 to 4 hours after a dose. Effect of Food Systemic exposure to pazopanib is increased when administered with food. Administration of pazopanib with a high-fat (approximately 50% fat) or low-fat (approximately 5% fat) meal results in an approximately 2-fold increase in AUC and C max . Distribution Binding of pazopanib to human plasma protein in vivo was > 99% with no concentration dependence over the range of 10 to 100 mcg/mL. In vitro studies suggest that pazopanib is a substrate for P-gp and BCRP. Elimination Pazopanib has a mean half-life of 31 hours after administration of the recommended dose of 800 mg. Metabolism In vitro studies demonstrated that pazopanib is metabolized by CYP3A4 with a minor contribution from CYP1A2 and CYP2C8. Excretion Elimination is primarily via feces with renal elimination accounting for < 4% of the administered dose. Specific Populations Patients with Hepatic Impairment Table 7 presents a comparison of the median steady-state C max and the median AUC 0-24h values for patients with normal, mild, moderate and severe hepatic impairment. The median steady-state of pazopanib C max and AUC 0-24h after a once-daily dose of 800 mg in patients with mild impairment were in a similar range as the median steady-state C max and median AUC 0-24h in patients with no hepatic impairment. The maximum tolerated pazopanib dose in patients with moderate hepatic impairment was 200 mg once daily. The median steady-state C max and the median AUC 0-24h were approximately 43% and 29%, respectively, of the corresponding median values after administration of 800 mg once daily in patients with no hepatic impairment. The median steady-state C max and the median AUC 0-24h were approximately 18% and 15%, respectively, of the corresponding median values after administration of 800 mg once daily in patients with no hepatic impairment.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility The carcinogenic potential of pazopanib was evaluated in CD-1 mice, and Sprague-Dawley rats. Administration of pazopanib to mice for 2 years did not result in increased incidence of neoplasms at doses up to 100 mg/kg/day (approximately 1.4-fold the AUC at the MRHD of 800 mg/day). Administration of pazopanib to rats for 2 years resulted in findings of duodenal adenocarcinoma in males at 30 mg/kg/day (approximately 0.3-fold the AUC at the MRHD of 800 mg/day) and in females at greater than or equal to 10 mg/kg/day (approximately 0.3-fold the AUC at the MRHD of 800 mg/day). The human relevance of these neoplastic findings is unclear. Pazopanib did not induce mutations in the microbial mutagenesis (Ames) assay and was not clastogenic in both the in vitro cytogenetic assay using primary human lymphocytes and in the in vivo rat micronucleus assay. In an oral female fertility and early embryonic development study, female rats were administered pazopanib at least 15 days prior to mating, and for 6 days after mating. Pazopanib did affect fertility in female rats. Reduced fertility, including increased pre-implantation loss and early resorptions, were noted at dosages greater than or equal to 30 mg/kg/day (approximately 0.4-fold the AUC at the MRHD of 800 mg/day). Decreased corpora lutea and increased cysts were noted in mice given greater than or equal to 100 mg/kg/day for 13 weeks and ovarian atrophy was noted in rats given greater than or equal to 300 mg/kg/day for 26 weeks (approximately 1.3 and 0.85-fold the AUC at the MRHD of 800 mg/day). Decreased corpora lutea was also noted in monkeys given 500 mg/kg/day for up to 34 weeks (approximately 0.4-fold the AUC at the MRHD of 800 mg/day). Pazopanib did not affect mating or fertility in male rats. However, there were reductions in sperm production rates and testicular sperm concentrations at doses greater than or equal to 3 mg/kg/day, epididymal sperm concentrations at doses greater than or equal to 30 mg/kg/day, and sperm motility at greater than or equal to 100 mg/kg/day following 15 weeks of dosing. Following 15 and 26 weeks of dosing, there were decreased testicular and epididymal weights at doses of greater than or equal to 30 mg/kg/day (approximately 0.35-fold the AUC at the MRHD of 800 mg/day); atrophy and degeneration of the testes with aspermia, hypospermia, and cribiform change in the epididymis was also observed at this dose in the 6-month toxicity studies in male rats.

    Clinical Studies

    14 CLINICAL STUDIES 14.1 Renal Cell Carcinoma The efficacy of pazopanib was evaluated in VEG105192, a randomized, double-blind, placebo-controlled, multicenter trial (NCT00387764). Patients with locally advanced and/or metastatic RCC who had received either no prior therapy or one prior cytokine-based systemic therapy were randomized (2:1) to receive pazopanib 800 mg once daily or placebo once daily. Eligible subjects were stratified according to the following 3 stratification factors: baseline ECOG performance status 0 versus 1; prior nephrectomy yes versus no; and prior systemic therapy for advanced RCC: treatment-naïve versus one prior cytokine-based therapy. The major efficacy outcome measure was progression-free survival (PFS). Additional outcome measures were overall survival (OS), overall response rate (ORR), and duration of response. Of the total of 435 patients enrolled in this trial, 233 patients had no prior systemic therapy (treatment-naïve subgroup) and 202 patients received one prior IL-2 or INFα-based therapy (cytokine-pretreated subgroup). The baseline demographic and disease characteristics were balanced between the arms receiving pazopanib and placebo. The majority of patients were male (71%) with a median age of 59 years. Eighty-six percent of patients were white, 14% were Asian, and < 1% were other. Forty-two percent were ECOG performance status 0 and 58% were ECOG performance status 1. All patients had clear cell histology (90%) or predominantly clear cell histology (10%). Approximately 50% of all patients had 3 or more organs involved with metastatic disease. The most common metastatic sites at baseline were lung (74%), lymph nodes (56%), bone (27%), and liver (25%). A similar proportion of patients in each arm were treatment-naïve and cytokine-pretreated (see Table 8). In the cytokine-pretreated subgroup, the majority (75%) had received interferon-based treatment. Similar proportions of patients in each arm had prior nephrectomy (89% and 88% for pazopanib and placebo, respectively). The analysis of the primary endpoint PFS was based on disease assessment by independent radiological review in the entire trial population. Efficacy results are presented in Table 8 and Figure 1.

Figure 1. Kaplan-Meier Curve for Progression-free Survival in RCC by Independent Assessment for the Overall Population (Treatment-naïve and Cytokine Pre-treated Populations) in VEG105192 At the protocol-specified final analysis of OS, the median OS was 22.9 months for patients randomized to pazopanib and 20.5 months for the placebo arm [HR = 0.91 (95% CI: 0.71, 1.16)]. The median OS for the placebo arm includes 79 patients (54%) who discontinued placebo treatment because of disease progression and crossed over to treatment with pazopanib. In the placebo arm, 95 (66%) patients received at least one systemic anticancer treatment after progression compared with 88 (30%) patients randomized to pazopanib. 1 14.2 Soft Tissue Sarcoma The efficacy of pazopanib was evaluated in VEG110727, a randomized, double-blind, placebo-controlled, multicenter trial (NCT00753688). Patients with metastatic STS who had received prior chemotherapy, including anthracycline treatment, or were unsuited for such therapy, were randomized (2:1) to receive pazopanib 800 mg once daily or placebo. Patients with gastrointestinal stromal tumors (GIST) or adipocytic sarcoma were excluded from the trial. Randomization was stratified by the factors of WHO performance status (WHO PS) 0 or 1 at baseline and the number of lines of prior systemic therapy for advanced disease (0 or 1 versus 2+). The major efficacy outcome measure was PFS assessed by independent radiological review. Additional outcome measures were OS, ORR, and duration of response. The majority of patients were female (59%) with a median age of 55 years. Seventy-two percent of patients were white, 22% were Asian, and 6% were other. Forty-three percent of patients had leiomyosarcoma, 10% had synovial sarcoma, and 47% had other soft tissue sarcomas. Fifty-six percent of patients had received 2 or more lines of prior systemic therapy and 44% had received 0 or 1 lines of prior systemic therapy.

    Geriatric Use

    8.5 Geriatric Use In pooled clinical trials with pazopanib, 30% of 2080 patients were aged ≥ 65 years. More patients ≥ 65 years had ALT elevations > 3 × ULN compared to patients < 65 years (23% versus 18%) [see Warnings and Precautions ( 5.1 )] . In the RCC trials, 33% of 586 patients were aged ≥ 65 years. No overall differences in safety or effectiveness of pazopanib were observed between these patients and younger patients. In the STS trials, 24% of 382 patients were aged ≥ 65 years. Patients aged ≥ 65 years had a higher incidence of Grade 3 or 4 fatigue (19% versus 12% for patients aged < 65 years), hypertension (10% versus 6%), decreased appetite (11% versus 2%), ALT elevations (3% versus 2%) and AST elevations (4% versus 1%). In the randomized STS trial (VEG110727), no overall differences in effectiveness of pazopanib were observed between patients aged ≥ 65 years and younger patients.

    Labor And Delivery

    8.2 Lactation Risk Summary There is no data on the presence of pazopanib or its metabolites in human milk or their effects on the breastfed infant or milk production. Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with pazopanib and for 2 weeks after the final dose.

    Nursing Mothers

    8.3 Females and Males of Reproductive Potential Pazopanib can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify pregnancy status of females of reproductive potential prior to starting treatment with pazopanib. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with pazopanib and for at least 2 weeks after the last dose. Males Advise males (including those who have had vasectomies) with female partners of reproductive potential to use condoms during treatment with pazopanib and for at least 2 weeks after the last dose. Infertility Based on findings from animal studies, pazopanib may impair fertility in females and males of reproductive potential while receiving treatment [see Nonclinical Toxicology ( 13.1 )] .

    Pediatric Use

    8.4 Pediatric Use The safety and effectiveness of pazopanib in pediatric patients have not been established. Juvenile Animal Toxicity Data In rats, weaning occurs at Day 21 postpartum which approximately equates to a human pediatric age of 2 years. In a juvenile animal toxicology study performed in rats, when animals were dosed from Day 9 through Day 14 postpartum (pre-weaning), pazopanib caused abnormal organ growth/maturation in the kidney, lung, liver, and heart at approximately 0.1-fold the AUC in adults at the MRHD of 800 mg/day of pazopanib. At approximately 0.4-fold the AUC in adults at the MRHD of 800 mg/day, pazopanib administration resulted in mortality. In repeat-dose toxicology studies in rats, including 4-week, 13-week, and 26-week administration, toxicities in bone, teeth, and nail beds were observed at doses greater than or equal to 3 mg/kg/day (approximately 0.07-fold the AUC at the MRHD of 800 mg/day). Doses of 300 mg/kg/day (approximately 0.8-fold the AUC at the MRHD of 800 mg/day) were not tolerated in 13- and 26-week studies and animals required dose reductions due to body weight loss and morbidity. Hypertrophy of epiphyseal growth plates, nail abnormalities (including broken, overgrown, or absent nails) and tooth abnormalities in growing incisor teeth (including excessively long, brittle, broken, and missing teeth, and dentine and enamel degeneration and thinning) were observed in rats at doses greater than or equal to 30 mg/kg/day (approximately 0.35-fold the AUC at the MRHD of 800 mg/day) at 26 weeks, with the onset of tooth and nail bed alterations noted clinically after 4 to 6 weeks. Similar findings were noted in repeat-dose studies in juvenile rats dosed with pazopanib beginning Day 21 postpartum (post-weaning). In the post-weaning animals, the occurrence of changes in teeth and bones occurred earlier and with greater severity than in older animals. There was evidence of tooth degeneration and decreased bone growth at doses greater than or equal to 30 mg/kg (approximately 0.1- to 0.2-fold the AUC at the MRHD of 800 mg/day). Pazopanib exposure in juvenile rats was lower than that seen at the same dose levels in adult animals, based on comparative AUC values. At pazopanib doses approximately 0.5- to 0.7-fold the AUC at the MRHD of 800 mg/day, decreased bone growth in juvenile rats persisted even after the end of the dosing period. Finally, despite lower pazopanib exposures than those reported in adult animals or adult humans, juvenile animals administered 300 mg/kg/dose pazopanib required dose reduction within 4 weeks of dosing initiation due to significant toxicity, although adult animals could tolerate this same dose for at least 3 times as long [see Warnings and Precautions ( 5.18 )] .

    Pregnancy

    8.1 Pregnancy Risk Summary Based on animal reproduction studies and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , pazopanib can cause fetal harm when administered to a pregnant woman. There are no available data on pazopanib use in pregnant women to evaluate for a drug-associated risk. In animal developmental and reproductive toxicology studies, oral administration of pazopanib to pregnant rats and rabbits throughout organogenesis resulted in teratogenicity, and abortion at systemic exposures lower than that observed at the MRHD of 800 mg/day (based on AUC) (see Data) . Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects in clinically recognized pregnancies and miscarriage is 2% to 4% and 15% to 20%, respectively. Data Animal Data In a female fertility and early embryonic development study, female rats were administered oral pazopanib at least 15 days prior to mating and for 6 days after mating, which resulted in increased pre-implantation loss and early resorptions at dosages greater than or equal to 30 mg/kg/day (approximately 0.4-fold the AUC at the MRHD of 800 mg/day). Total litter resorption was seen at 300 mg/kg/day (approximately 0.8-fold the AUC at the MRHD of 800 mg/day). Postimplantation loss, embryolethality, and decreased fetal body weights were noted in females administered doses greater than or equal to 10 mg/kg/day (approximately 0.3-fold the AUC at the MRHD of 800 mg/day). In embryo-fetal developmental toxicity studies in rats and rabbits, oral pazopanib was administered to pregnant animals during organogenesis. In rats, dose levels of greater than or equal to 3 mg/kg/day (approximately 0.1-fold the AUC at the MRHD of 800 mg/day) resulted in teratogenic effects, including cardiovascular malformations (retroesophageal subclavian artery, missing innominate artery, changes in the aortic arch), incomplete or absent ossification, increases in postimplantation loss, embryolethality and reduced fetal body weight. In rabbits, maternal toxicity, increased postimplantation loss and abortion were observed at doses greater than or equal to 30 mg/kg/day (approximately 0.007-fold the AUC at the MRHD of 800 mg/day). In addition, severe maternal body weight loss and 100% litter loss were observed at doses greater than or equal to 100 mg/kg/day (0.02-fold the AUC at the MRHD of 800 mg/day), while fetal weight was reduced at doses greater than or equal to 3 mg/kg/day (AUC not calculated).

    8 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on animal reproduction studies and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , pazopanib can cause fetal harm when administered to a pregnant woman. There are no available data on pazopanib use in pregnant women to evaluate for a drug-associated risk.

Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with pazopanib and for 2 weeks after the final dose. 8.3 Females and Males of Reproductive Potential Pazopanib can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify pregnancy status of females of reproductive potential prior to starting treatment with pazopanib. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with pazopanib and for at least 2 weeks after the last dose. Males Advise males (including those who have had vasectomies) with female partners of reproductive potential to use condoms during treatment with pazopanib and for at least 2 weeks after the last dose. Infertility Based on findings from animal studies, pazopanib may impair fertility in females and males of reproductive potential while receiving treatment [see Nonclinical Toxicology ( 13.1 )] . 8.4 Pediatric Use The safety and effectiveness of pazopanib in pediatric patients have not been established. Juvenile Animal Toxicity Data In rats, weaning occurs at Day 21 postpartum which approximately equates to a human pediatric age of 2 years. In a juvenile animal toxicology study performed in rats, when animals were dosed from Day 9 through Day 14 postpartum (pre-weaning), pazopanib caused abnormal organ growth/maturation in the kidney, lung, liver, and heart at approximately 0.1-fold the AUC in adults at the MRHD of 800 mg/day of pazopanib. At approximately 0.4-fold the AUC in adults at the MRHD of 800 mg/day, pazopanib administration resulted in mortality. In repeat-dose toxicology studies in rats, including 4-week, 13-week, and 26-week administration, toxicities in bone, teeth, and nail beds were observed at doses greater than or equal to 3 mg/kg/day (approximately 0.07-fold the AUC at the MRHD of 800 mg/day). Doses of 300 mg/kg/day (approximately 0.8-fold the AUC at the MRHD of 800 mg/day) were not tolerated in 13- and 26-week studies and animals required dose reductions due to body weight loss and morbidity. Hypertrophy of epiphyseal growth plates, nail abnormalities (including broken, overgrown, or absent nails) and tooth abnormalities in growing incisor teeth (including excessively long, brittle, broken, and missing teeth, and dentine and enamel degeneration and thinning) were observed in rats at doses greater than or equal to 30 mg/kg/day (approximately 0.35-fold the AUC at the MRHD of 800 mg/day) at 26 weeks, with the onset of tooth and nail bed alterations noted clinically after 4 to 6 weeks. Similar findings were noted in repeat-dose studies in juvenile rats dosed with pazopanib beginning Day 21 postpartum (post-weaning). In the post-weaning animals, the occurrence of changes in teeth and bones occurred earlier and with greater severity than in older animals. There was evidence of tooth degeneration and decreased bone growth at doses greater than or equal to 30 mg/kg (approximately 0.1- to 0.2-fold the AUC at the MRHD of 800 mg/day). Pazopanib exposure in juvenile rats was lower than that seen at the same dose levels in adult animals, based on comparative AUC values. At pazopanib doses approximately 0.5- to 0.7-fold the AUC at the MRHD of 800 mg/day, decreased bone growth in juvenile rats persisted even after the end of the dosing period. Finally, despite lower pazopanib exposures than those reported in adult animals or adult humans, juvenile animals administered 300 mg/kg/dose pazopanib required dose reduction within 4 weeks of dosing initiation due to significant toxicity, although adult animals could tolerate this same dose for at least 3 times as long [see Warnings and Precautions ( 5.18 )] . 8.5 Geriatric Use In pooled clinical trials with pazopanib, 30% of 2080 patients were aged ≥ 65 years. More patients ≥ 65 years had ALT elevations > 3 × ULN compared to patients < 65 years (23% versus 18%) [see Warnings and Precautions ( 5.1 )] . In the RCC trials, 33% of 586 patients were aged ≥ 65 years. No overall differences in safety or effectiveness of pazopanib were observed between these patients and younger patients. In the STS trials, 24% of 382 patients were aged ≥ 65 years. Patients aged ≥ 65 years had a higher incidence of Grade 3 or 4 fatigue (19% versus 12% for patients aged < 65 years), hypertension (10% versus 6%), decreased appetite (11% versus 2%), ALT elevations (3% versus 2%) and AST elevations (4% versus 1%). In the randomized STS trial (VEG110727), no overall differences in effectiveness of pazopanib were observed between patients aged ≥ 65 years and younger patients. 8.6 Renal Impairment No dose adjustment is recommended for patients with renal impairment. Pazopanib has not been studied in patients with severe renal impairment or in patients undergoing peritoneal dialysis or hemodialysis. 8.7 Hepatic Impairment No dose adjustment is required in patients with mild hepatic impairment (either total bilirubin ≤ ULN and ALT > ULN or bilirubin > 1 to 1.5 × ULN and any ALT value). Pazopanib is not recommended in patients with moderate (total bilirubin > 1.5 to 3 × ULN and any ALT value) and severe (total bilirubin > 3 × ULN and any ALT value) hepatic impairment [see Dosage and Administration ( 2.3 ), Clinical Pharmacology ( 12.3 )] .
