Participant Flow

Subjects were enrolled at 324 sites in the United States from 16 February 2007 to 12 March 2008.

Subjects who were currently receiving urate-lowering therapy discontinued those urate-lowering therapies and initiated prophylactic medications before enrollemnt in once daily (QD) treatment groups.

PRIMARY outcome

Timeframe: Last Visit on treatment (up to 6 months)

Population: Analysis was performed on intent-to-treat (ITT) subjects, which were defined as all randomized subjects who took at least 1 dose of study drug and who had baseline serum urate ≥8.0 mg/dL. A subject's baseline value was used in the primary analysis if no postbaseline serum urate level was obtained.

The percentage of subjects whose serum urate level was \<6.0 mg/dL at the Final Visit was summarized. The Final Visit was the last visit at which a serum urate value was collected.

Timeframe: Last Visit on treatment (up to 6 months)

Population: Analysis was performed on the ITT subjects with mild-to-moderate renal impairment (estimated creatinine clearance of 30 mL/min to 89 mL/min), with a post-baseline serum urate level.

The percentage of subjects with mild-to-moderate renal impairment whose serum urate was \<6.0 mg/dL at the final visit was summarized. The final visit was the last visit at which a serum urate value was collected.
