Arms	Assigned Interventions
1: Experimental	Drug: Febuxostat Febuxostat 80 mg daily, capsules administered orally for 1 year.
2: Experimental	Drug: Febuxostat Febuxostat 120 mg daily, capsules administered orally for 1 year.
3: Active Comparator	Drug: Allopurinol Allopurinol 300 mg capsules administered orally, daily, for 1 year.

Detailed Description:

This was a randomized, controlled, double-blind study of 52 weeks duration. Subjects receiving prior urate-lowering therapy underwent a 2-week washout period prior to randomization. Subjects were then randomized to one of three treatment groups: febuxostat 80 mg, febuxostat 120 mg, or allopurinol 300 mg. Naproxen (250 mg twice daily) or colchicine (0.6 mg once daily) was provided for prophylaxis of acute gout flares during the washout period and the first 8 weeks of double-blind treatment.
