Primary Outcome Measures:
- Percentage of Subjects Whose Serum Urate Level is <6.0 Milligrams Per Deciliter (mg/dL) at the Final Visit. [ Time Frame: Last Visit on treatment (up to 6 months) ]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.

- Percentage of Subjects Whose Serum Urate Levels Are <5.0 mg/dL at Final Visit. [ Time Frame: Last Visit on treatment (up to 6 months) ]The percentage of subjects whose serum urate level was <5.0 mg/dL at the Final Visit was summarized. The Final Visit was the last visit at which a serum urate values was collected.
- Percentage of Subjects Whose Serum Urate Levels Are <4.0 mg/dL at Month 2 Visit [ Time Frame: Month 2 ]Serum urate values were obtained at the Month 2 visit. The percentage of subjects whose serum urate was <4.0 mg/dL at the Month 2 visit was summarized.

Detailed Description:
Renal impairment is common in subjects with gout, with the prevalence ranging from 50% to 70%. This population represents an unmet medical need as uricosuric drugs are contraindicated in these patients, and the only available treatment, allopurinol, may have to be dose reduced to avoid overt side effects.
Febuxostat (TMX-67) is a non-purine selective xanthine oxidase inhibitor being developed as an orally administered agent for management of hyperuricemia in patients with gout.
Treatment duration will be 6 months.
