Pazopanib is indicated for the treatment of patients with advanced renal cell carcinoma (RCC). Pazopanib is indicated for the treatment of patients with advanced soft tissue sarcoma (STS) who have received prior chemotherapy. The efficacy of Pazopanib for the treatment of patients with adipocytic STS or gastrointestinal stromal tumors has not been demonstrated.

The recommended starting dose of Pazopanib is 800 mg orally once daily without food (at least 1 hour before or 2 hours after a meal). The dose of Pazopanib should not exceed 800 mg. Tablets should not be crushed due to the potential for increased rate of absorption which may affect systemic exposure. If a dose is missed, it should not be taken if it is less than 12 hours until the next dose. Or, as directed by the registered physicians.

It is contraindicated in patients with known hypersensitivity to Pazopanib or any other components of this product.

Common side effects of Pazopanib include:

• Hepatic Toxicity and Hepatic Impairment
• QT Prolongation and Torsades de Pointes
• Cardiac Dysfunction
• Hemorrhagic Events
• Arterial and Venous Thromboembolic Events
• Thrombotic Microangiopathy
• Gastrointestinal Perforation and Fistula
• Interstitial Lung Disease/Pneumonitis
• Reversible Posterior Leukoencephalopathy Syndrome
• Hypertension
• Hypothyroidism
• Proteinuria
• Tumor Lysis Syndrome
• Infection
• Increased Toxicity with Other Cancer Therapy

Overdose Effects

Pazopanib doses up to 2000 mg have been evaluated in clinical trials. Dose-limiting toxicity (Grade 3 fatigue) and Grade 3 hypertension were each observed in 1 of 3 patients dosed at 2000 mg daily and 1000 mg daily, respectively. Treatment of overdose with Pazopanib should consist of general supportive measures. There is no specific antidote for overdosage of Pazopanib. Hemodialysis is not expected to enhance the elimination of Pazopanib because Pazopanib is not significantly renally excreted and is highly bound to plasma proteins.

Hepatic Toxicity and Hepatic Impairment: In clinical trials with Pazopanib, hepatotoxicity, manifested as increases in serum transaminases (alanine transferase [ALT], aspartate aminotransferase [AST]) and bilirubin, was observed. This hepatotoxicity can be severe and fatal. Patients older than 65 years are at greater risk for hepatotoxicity. Transaminase elevations occur early in the course of treatment (92.5% of all transaminase elevations of any grade occurred in the first 18 weeks).

QT Prolongation and Torsades De Pointes: In the RCC trials of Pazopanib, QT prolongation (greater than or equal to 500 msec) was identified on routine electrocardiogram (ECG) monitoring in 2% (11/558) of patients. Torsades de pointes occurred in less than 1% (2/977) of patients who received Pazopanib in the monotherapy trials. Pazopanib should be used with caution in patients with a history of QT interval prolongation, in patients taking antiarrhythmics or other medications that may prolong QT interval, and those with relevant pre-existing cardiac disease. When using Pazopanib, baseline and periodic monitoring of ECGs and maintenance of electrolytes (e.g., calcium, magnesium, potassium) within the normal range should be performed.

Use in Special Populations

Females: Pazopanib can cause fetal harm when administered to a pregnant woman. Females of reproductive potential should be advised to use effective contraception during treatment and for at least 2 weeks after the last dose of Pazopanib.

Males: To avoid potential drug exposure to pregnant partners and female partners of reproductive potential, male patients (including those who have had vasectomies) with female partners of reproductive potential should be advised to use condoms during treatment with Pazopanib and for at least 2 weeks after the last dose.

Pediatric Use: The safety and effectiveness of Pazopanib in pediatric patients have not been established.

Pregnancy & Lactation

Pazopanib can cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform a drug-associated risk. Pregnant women or women should be advised of the childbearing potential of the potential risk to a fetus. There is no information regarding the presence of Pazopanib or its metabolites in human milk, or their effects on the breastfed infant, or on milk production. Because of the potential for serious adverse reactions in breastfed infants from Pazopanib, a lactating woman should be advised not to breastfeed during treatment with Pazopanib and for 2 weeks after the final dose.
