- Primary Outcome Measures
Name Time Method The primary objective of this study is to characterize the pharmacokinetic (PK) profile of the test formulation (pazopanib tablets 200 mg of Alembic Pharmaceuticals Limited, India.) relative to that of reference formulation (VOTRIENT�® tablets 200 mg) in patients of advanced RCC who are tolerating a stable dose of Pazopanib tablets 800 mg once daily and to assess the bioequivalence after multiple dose administration under fasting condition.Timepoint: Day 14 (Period I) and Day 28 (period II)
- Secondary Outcome Measures
Name Time Method The secondary objective of this study is to evaluate the safety and tolerability of the patients exposed to the pazopanib tablets 200 mg in patients of advanced RCC.Timepoint: Day 14 (Period I) and Day 28 (period II)
