Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Per protocol amendment, the number of participants (par.) was increased to ~1100 (including all par. enrolled in Studies VEG108844 and VEG113078 [NCT01147822; a substudy in Asian par.]). This summary is a pooled analysis of both studies. 1110 par. were analyzed; 927 from VEG108844 (reflected in the protocol enrollment field), 183 from VEG113078.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants were stratified based on Karnofsky Performance Scale scores (70 or 80; 90 or 100), Baseline levels of lactate dehydrogenase (>1.5 versus <=1.5 times the upper limit of normal [ULN]), and previous nephrectomy (yes versus no) and were randomized in a 1:1 ratio to receive either pazopanib or sunitinib.

Reporting Groups
  Description
Pazopanib 800 mg Participants were administered pazopanib 800 milligrams (mg) (2 x 400 mg tablets) orally once daily (OD) continuously. Pazopanib was to be taken at least one hour before or at least two hours after a meal. Participants received study treatment until disease progression, death, unacceptable toxicity, or withdrawal of consent for any other reasons.
Sunitinib 50 mg Participants were administered sunitinib 50 mg orally once daily in 6-week cycles (4 weeks of treatment, followed by 2 weeks without treatment). Participants received study treatment until disease progression, death, unacceptable toxicity, or withdrawal of consent for any other reasons.

Measure Type Secondary
Measure Title Number of Participants in the Indicated Categories for Overall Response as Assessed by Independent Review
Measure Description The number of participants with evidence of CR (the disappearance of all target and non-target lesions), PR (at least a 30% decrease in the sum of the longest diameters [LD] of target lesions, taking as a reference the Baseline sum LD), Stable Disease (small changes that do not meet previously given criteria), or Progressive Disease (a >=20% increase in target lesions within the first 12 weeks of treatment) was evaluated by an independent review per RECIST, Version 1.
Time Frame From randomization until the time of a confirmed best response of CR or PR (up to Study Week 167)  
Safety Issue No
