Pazopanib Versus Sunitinib in the Treatment of Locally Advanced and/or Metastatic Renal Cell Carcinoma (COMPARZ)

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.
