Renal Impairment
About this trial
This is an interventional treatment trial for Renal Impairment focused on measuring Gout, physiology, Hyperuricemia, Uric Acid, Drug Therapy

Febuxostat 30 mg, capsules, orally, twice daily (BID) for up to 12 months.
Participants initially received febuxostat 40 mg, capsules, once daily (QD) and one placebo-matching capsule QD and remained on this dose 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, capsule, QD, and one placebo-matching capsule QD at the Month 1 visit, and for the remainder of the study.
