Participant Flow

Participants took part in the study at 46 investigative sites in the United States from 09 April 2010 to 31 May 2012.

Participants meeting the American Rheumatism Association (ARA) diagnostic criteria for gout (subjects with tophi were excluded). were randomized to 1 of 3 arms in a 1:1:1 ratio to receive either febuxostat 40 mg/80 mg once daily (QD) or febuxostat 30 mg twice daily (BID) or placebo for up to 12 months.

Febuxostat 40/80 mg QD
Participants initially received 40 mg febuxostat once daily (QD) and remained on 40 mg QD for up to 12 months if their serum urate (sUA) was \<6.0 mg/dL at the Day 14 visit. Participants whose sUA was ≥6.0 mg/dL at the Day 14 visit received febuxostat 80 mg QD at the Month 1 visit, and for the remainder of the study.

PRIMARY outcome

Timeframe: Baseline and Month 12

Population: Full analysis set, including all patients who were randomized and received at least 1 dose of double-blind study medication. Only patients with both a baseline value and at least 1 value during the double-blind treatment period are included in the analysis. Missing data were imputed as carrying forward the last observed post-baseline value.

Renal function was assessed by measuring the change from Baseline in serum creatinine. Analyses were conducted by the Central Laboratory.
