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 Title Change From Baseline in the Supplementary Quality of Life Questions (SQLQ) Scale Worst Soreness Scores at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively)
Measure Description The SQLQ scale consists of 5 items that assess the worst mouth and throat, hand, and foot soreness, as well as limitations due to mouth/throat and foot soreness. Participants were asked to assess their worst mouth/throat, hand, and foot soreness by answering the question of " In the past 4 weeks, what was your worst mouth/throat, hand, and foot soreness?" by using the following 4-point scale: 0, I never had any soreness; 1, I had a little bit of soreness; 2, I had quite a lot of soreness; 3, I had severe soreness. A positive mean change from Baseline represents a worsening of condition.

ITT Population. Some participants were missing scores at Baseline and were excluded from the analysis. Participants missing scores at other early time points were excluded from the analysis at those time points. Change from Baseline was calculated as the assessment week value minus the Baseline value.
