Warning: Hepatotoxicity

Severe and fatal hepatotoxicity has been observed in clinical trials. Monitor hepatic function and interrupt, reduce, or discontinue dosing as recommended [see Warnings and Precautions ( 5.1)] .

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.

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

Abbreviations: ALT, alanine aminotransferase; ULN, upper limit of normal. ^aNational 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)] .

3 Dosage Forms And Strengths

Tablets: 200 mg, grey, biconvex, capsule shaped, film-coated tablet, marked with “T” on one side and “4184” on the other side.

4 Contraindications

None.

5.1 Hepatic Toxicity

Hepatotoxicity, manifested as increases in ALT, aspartate aminotransferase (AST) and bilirubin, occurred in patients who received pazopanib. This hepatotoxicity can be severe and fatal. Patients older than 65 years are at greater risk for hepatotoxicity [see Use in Specific Populations ( 8.5)] . Transaminase elevations occur early in the course of treatment; 92% of all transaminase elevations of any grade occurred in the first 18 weeks.

In the randomized RCC trial (VEG105192), ALT > 3 × ULN occurred in 18% and ALT > 10 × ULN occurred in 4% of the 290 patients who received pazopanib. Concurrent elevation in ALT > 3 × ULN and bilirubin > 2 × ULN in the absence of significant alkaline phosphatase > 3 × ULN occurred in 2%. In the monotherapy trials, 2 patients died with disease progression and hepatic failure.

In the randomized STS trial (VEG110727), ALT > 3 × ULN occurred in 18% and ALT > 8 × ULN occurred in 5% of the 240 patients who received pazopanib. Concurrent elevation in ALT > 3 × ULN and bilirubin > 2 × ULN in the absence of significant alkaline phosphatase > 3 × ULN occurred in 2%. One patient died of hepatic failure.

Monitor liver tests at baseline; at Weeks 3, 5, 7, and 9; at Month 3 and Month 4; and then periodically as clinically indicated. Increase to weekly monitoring for patients with elevated ALT until ALT returns to Grade 1 or baseline. Withhold pazopanib 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 [see Dosage and Administration ( 2.2)] .

Gilbert’s Syndrome

Pazopanib is a uridine diphosphate (UDP)-glucuronosyl transferase 1A1 (UGT1A1) inhibitor. Mild, indirect (unconjugated) hyperbilirubinemia may occur in patients with Gilbert’s syndrome [see Clinical Pharmacology (12.5)]. In patients with only a mild indirect hyperbilirubinemia known as Gilbert’s syndrome, manage elevation in ALT > 3 × ULN per the recommendations outlined for isolated ALT elevations [see Dosage and Administration ( 2.2)] .

Concomitant Use of Simvastatin

Concomitant use of pazopanib and simvastatin increases the risk of ALT elevations [see Drug Interactions ( 7.3)] . Insufficient data are available to assess the risk of concomitant administration of alternative statins and pazopanib.

5.2 Qt Prolongation And Torsades De Pointes

In the RCC trials, 558/586 patients were subject to routine electrocardiogram (ECG) monitoring and QT prolongation ≥ 500 msec was identified in 2% of these 558 patients. In monotherapy trials, torsades de pointes occurred in < 1% of 977 patients who received pazopanib.

In the randomized RCC (VEG105192) and STS (VEG110727) trials, 1% (3/290) and 0.4% (1/240) of patients, respectively, who received pazopanib had post-baseline values between 500 to 549 msec. Post-baseline QT data were only collected in the STS trial if ECG abnormalities were reported as an adverse reaction.

Monitor patients who are at significant risk of developing QTc prolongation, including patients with a history of QT interval prolongation, in patients taking antiarrhythmics or other medications that may prolong QT interval, and those with relevant preexisting cardiac disease [see Drug Interactions (7.5)]. Monitor ECG and electrolytes (e.g., calcium, magnesium, potassium) at baseline and as clinically indicated. Correct hypokalemia, hypomagnesemia, and hypocalcemia prior to initiating pazopanib and during treatment.

5.3 Cardiac Dysfunction

Cardiac dysfunction, including decreased left ventricular ejection fraction (LVEF) and congestive heart failure, occurred in patients who received pazopanib.

In the RCC trials, cardiac dysfunction was observed in 0.6% of 586 patients without routine on-study LVEF monitoring. In the randomized RCC trial (VEG105192), myocardial dysfunction was defined as symptoms of cardiac dysfunction or ≥ 15% absolute decline in LVEF compared with baseline or a decline in LVEF of ≥ 10% compared with baseline that is also below the lower limit of normal. In an RCC trial (COMPARZ), myocardial dysfunction occurred in 13% of the 362 patients on pazopanib who had a baseline and post-baseline LVEF measurements. Congestive heart failure occurred in 0.5% of patients.

In the randomized STS trial (VEG110727), myocardial dysfunction occurred in 11% of the 142 patients who had a baseline and a post-baseline LVEF measurements. One percent (3/240) of patients who received pazopanib had congestive heart failure, which did not resolve in one patient. Fourteen of the 16 patients with myocardial dysfunction treated with pazopanib had concurrent hypertension which may have exacerbated cardiac dysfunction in patients at risk (e.g., those with prior anthracycline therapy) possibly by increasing cardiac afterload.

Monitor blood pressure and manage as appropriate [see Warnings and Precautions (5.11)]. Monitor for clinical signs or symptoms of congestive heart failure. Conduct baseline and periodic evaluation of LVEF in patients at risk of cardiac dysfunction, including previous anthracycline exposure. Withhold or permanently discontinue pazopanib based on severity of cardiac dysfunction [see Dosage and Administration ( 2.2)] .

5.4 Hemorrhagic Events

In the RCC trials, fatal hemorrhage occurred in 0.9% of 586 patients, and cerebral/intracranial hemorrhage was observed in < 1% (2/586) of patients treated with pazopanib.

In the randomized RCC trial (VEG105192), 13% of 290 patients treated with pazopanib experienced at least 1 hemorrhagic event. The most common hemorrhagic events were hematuria (4%), epistaxis (2%), hemoptysis (2%), and rectal hemorrhage (1%). Nine of 37 patients treated with pazopanib who had hemorrhagic events experienced serious events, including pulmonary, gastrointestinal, and genitourinary hemorrhage. One percent of patients treated with pazopanib died from hemorrhage.

In the randomized STS trial (VEG110727), 22% of 240 patients treated with pazopanib experienced at least 1 hemorrhagic event. The most common hemorrhagic events were epistaxis (8%), mouth hemorrhage (3%), and anal hemorrhage (2%). Grade 4 hemorrhagic events occurred in 1% of patients and included intracranial hemorrhage, subarachnoid hemorrhage, and peritoneal hemorrhage.

Pazopanib has 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 and resume at reduced dose or permanently discontinue based on severity of hemorrhagic events [see Dosage and Administration ( 2.2)] .

5.5 Arterial Thromboembolic Events

In the RCC trials, fatal arterial thromboembolic events occurred in 0.3% of 586 patients. In the randomized RCC trial (VEG105192), 2% of 290 patients who received pazopanib experienced myocardial infarction or ischemia, 0.3% had a cerebrovascular accident, and 1% had an event of transient ischemic attack.

In the randomized STS trial (VEG110727), 2% of 240 patients who received pazopanib experienced a myocardial infarction or ischemia and 0.4% had a cerebrovascular accident.

Pazopanib has not been studied in patients who have had an arterial thromboembolic event within the previous 6 months. Permanently discontinue pazopanib in case of an arterial thromboembolic event [see Dosage and Administration ( 2.2)] .

5.6 Venous Thromboembolic Events

Venous thromboembolic events (VTEs), including venous thrombosis and fatal pulmonary embolus (PE), occurred in patients who received pazopanib.

In the randomized RCC trial (VEG105192), VTEs occurred in 1% of 290 patients who received pazopanib. In the randomized STS trial (VEG110727), VTEs were reported in 5% of 240 patients who received pazopanib. Fatal PE occurred in 1% (2/240).

Monitor for signs and symptoms of VTE and PE. Withhold pazopanib and then resume at same dose or permanently discontinue based on severity of VTE [see Dosage and Administration ( 2.2)] .

5.7 Thrombotic Microangiopathy

Thrombotic microangiopathy (TMA), including thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS), occurred in clinical trials of pazopanib as monotherapy, in combination with bevacizumab, and in combination with topotecan. Pazopanib is not indicated for use in combination with other agents. Six of the 7 TMA cases occurred within 90 days of the initiation of pazopanib. Improvement of TMA was observed after treatment was discontinued.

Monitor for signs and symptoms of TMA. Permanently discontinue pazopanib in patients developing TMA. Manage as clinically indicated.

5.8 Gastrointestinal Perforation And Fistula

In the RCC and STS trials, gastrointestinal perforation or fistula occurred in 0.9% of 586 patients and 1% of 382 patients who received pazopanib, respectively. Fatal perforations occurred in 0.3% (2/586) of these patients in the RCC trials and in 0.3% (1/382) of these patients in the STS trials.

Monitor for signs and symptoms of gastrointestinal perforation or fistula. Withhold pazopanib in case of Grade 2 or 3 gastrointestinal fistula and resume based on medical judgement. Permanently discontinue pazopanib in case of gastrointestinal perforation or Grade 4 gastrointestinal fistula [see Dosage and Administration ( 2.2)] .

5.9 Interstitial Lung Disease/Pneumonitis

Interstitial lung disease (ILD)/pneumonitis, which can be fatal, has been reported with pazopanib across clinical trials. ILD/pneumonitis occurred in 0.1% of patients treated with pazopanib.

Monitor patients for pulmonary symptoms indicative of ILD/pneumonitis. Permanently discontinue pazopanib in patients who develop ILD or pneumonitis [see Dosage and Administration ( 2.2)] .

5.10 Posterior Reversible Encephalopathy Syndrome

Posterior Reversible Encephalopathy Syndrome (PRES) has been reported in patients who received pazopanib and may be fatal. PRES is a neurological disorder which can present with headache, seizure, lethargy, confusion, blindness, and other visual and neurologic disturbances. Mild to severe hypertension may be present. Confirm diagnosis of PRES by magnetic resonance imaging.

Permanently discontinue pazopanib in patients who develop PRES.

5.11 Hypertension

Hypertension (systolic blood pressure ≥ 150 mmHg or diastolic blood pressure ≥ 100 mmHg) and hypertensive crisis were observed in patients treated with pazopanib.

Approximately 40% of patients who received pazopanib experienced hypertension, with Grade 3 occurring in 4% to 7% of patients [see Adverse Reactions ( 6.1)] . About 40% of cases occurred by Day 9 and about 90% of cases occurred in the first 18 weeks across clinical trials. Approximately 1% of patients required permanent discontinuation of pazopanib because of hypertension.

Do not initiate pazopanib in patients with uncontrolled hypertension. Optimize blood pressure prior to initiating pazopanib. Monitor blood pressure as clinically indicated and initiate and adjust antihypertensive therapy as appropriate. Withhold and then dose reduce pazopanib or permanently discontinue based on severity of hypertension [see Dosage and Administration ( 2.2)] .

5.12 Risk Of Impaired Wound Healing

Impaired wound healing complications can occur in patients who receive drugs that inhibit the vascular endothelial growth factor (VEGF) signaling pathway. Therefore, pazopanib has the potential to adversely affect wound healing.

Withhold pazopanib at least 1 week 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 pazopanib after resolution of wound healing complications has not been established.

5.13 Hypothyroidism

Hypothyroidism, confirmed based on a simultaneous rise of TSH and decline of T4, occurred in 7% of 290 patients who received pazopanib in the randomized RCC trial (VEG105192) and in 5% of 240 patients who received pazopanib in the randomized STS trial (VEG110727). Hypothyroidism occurred in 4% of the 586 patients in the RCC trials and 5% of the 382 patients in the STS trials.

Monitor thyroid tests at baseline, during treatment and as clinically indicated and manage hypothyroidism as appropriate.

5.14 Proteinuria

In the randomized RCC trial (VEG105192), proteinuria occurred in 9% of 290 patients who received pazopanib. In 2 patients, proteinuria led to discontinuation of pazopanib.

In the randomized STS trial (VEG110727), proteinuria occurred in 1% of 240 patients and nephrotic syndrome occurred in 1 patient. Treatment was discontinued in the patient with nephrotic syndrome.

Perform baseline and periodic urinalysis during treatment with follow up measurement of 24-hour urine protein as clinically indicated. Withhold pazopanib then resume at a reduced dose or permanently discontinue based on severity of proteinuria. Permanently discontinue in patients with nephrotic syndrome [see Dosage and Administration ( 2.2)] .

5.15 Tumor Lysis Syndrome

Cases of tumor lysis syndrome (TLS), including fatal cases, have been reported in RCC and STS patients treated with pazopanib [see Adverse Reactions (6.2)]. Patients may be at risk of TLS if they have rapidly growing tumors, a high tumor burden, renal dysfunction, or dehydration. Closely monitor patients at risk, consider appropriate prophylaxis, and treat as clinically indicated.

5.16 Infection

Serious infections (with or without neutropenia), including some with fatal outcome, have been reported. Monitor patients for signs and symptoms of infection. Institute appropriate anti-infective therapy promptly and consider interruption or discontinuation of pazopanib for serious infections.

5.17 Increased Toxicity With Other Cancer Therapy

Pazopanib is not indicated for use in combination with other agents. Clinical trials of pazopanib in combination with pemetrexed and lapatinib were terminated early due to increased toxicity and mortality. The fatal toxicities observed included pulmonary hemorrhage, gastrointestinal hemorrhage, and sudden death. A safe and effective combination dose has not been established with these regimens.

5.18 Increased Toxicity In Developing Organs

The safety and effectiveness of pazopanib in pediatric patients have not been established. Pazopanib is not indicated for use in pediatric patients. Based on its mechanism of action, pazopanib may have severe effects on organ growth and maturation during early postnatal development. Administration of pazopanib to juvenile rats < 21 days old resulted in toxicity to the lungs, liver, heart, and kidney and in death at doses significantly lower than the clinically recommended dose or doses tolerated in older animals. Pazopanib may potentially cause serious adverse effects on organ development in pediatric patients, particularly in patients younger than 2 years of age [see Use in Specific Populations ( 8.4)] .

5.19 Embryo-Fetal Toxicity

Based on findings from animal studies and its mechanism of action, pazopanib can cause fetal harm when administered to a pregnant woman. Administration of pazopanib to pregnant rats and rabbits during the period of organogenesis resulted in maternal toxicity, teratogenicity, and abortion at systemic exposures lower than that observed at the maximum recommended human dose (MRHD) of 800 mg (based on area under the curve [AUC]).

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with pazopanib and for at least 2 weeks following the final dose. 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 [see Use in Specific Populations ( 8.1, 8.3)] .

6.1 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 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.

Additional adverse reactions from other clinical trials in patients with RCC who received pazopanib include arthralgia and muscle spasms.

Soft Tissue Sarcoma

The safety of pazopanib was evaluated in 240 patients who participated in VEG110727, a randomized, double-blind, placebo-controlled trial [see Clinical Studies ( 14.2)] . The median duration of treatment was 4.5 months (range, 0 to 24) for patients who received pazopanib.

Fifty-eight percent of patients on pazopanib required a dose interruption and 38% required a dose reduction. Seventeen percent of patients who received pazopanib discontinued therapy due to adverse reactions.

Table 5 presents the adverse reactions in VEG110727.

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)

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.

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).

8.2 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.

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)] .

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.

11 Description

Pazopanib is a kinase inhibitor. Pazopanib is presented as the hydrochloride salt, with the chemical name 5-[[4-[(2,3-dimethyl-2H-indazol-6-yl)methylamino]-2-pyrimidinyl]amino]-2-methylbenzenesulfonamide hydrochloride. It has the molecular formula C ₂₁H ₂₃N ₇O ₂S•HCl and a molecular weight of 473.99 g/mol. Pazopanib hydrochloride has the following chemical structure:

New (Pazopanib Tablets 200 mg A217517 1)

Pazopanib hydrochloride is a white to slightly yellow solid. It is very slightly soluble at pH 1 and practically insoluble above pH 4 in aqueous media.

Pazopanib tablets are for oral use. Each 200 mg tablet of pazopanib contains 200 mg of pazopanib equivalent to 216.7 mg of pazopanib hydrochloride. The inactive ingredients of pazopanib tablets are: Tablet Core:Magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate. Coating:Grey film-coat: hypromellose 2910, iron oxide black, polyethylene glycol 400, polysorbate 80, and titanium dioxide.

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 _maxof 58.1 mcg/mL. There was no consistent increase in AUC or C _maxat pazopanib doses above 800 mg.

Administration of a single 400-mg crushed tablet increased AUC _0-72hby 46% and C _maxby approximately 2-fold and decreased T _maxby 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 vivowas > 99% with no concentration dependence over the range of 10 to 100 mcg/mL. In vitrostudies 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 vitrostudies 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 _maxand the median AUC _0-24hvalues for patients with normal, mild, moderate and severe hepatic impairment.

The median steady-state of pazopanib C _maxand AUC _0-24hafter a once-daily dose of 800 mg in patients with mild impairment were in a similar range as the median steady-state C _maxand median AUC _0-24hin 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 _maxand the median AUC _0-24hwere 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 _maxand the median AUC _0-24hwere 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 _0-24hand a 1.5-fold increase in the C _maxof 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 _0-24hand 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 _maxof 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 vitrostudies 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 vitrohuman pregnane X receptor (PXR) assay.

In vitrostudies also showed that pazopanib inhibits UGT1A1 and organic anion-transporting polypeptide (OATP1B1) with IC ₅₀s 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 vitrostudies 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)] .

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 vitrocytogenetic assay using primary human lymphocytes and in the in vivorat 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.

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.

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.

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.

Efficacy results are presented in Table 9 and Figure 2.
