- Alanine aminotransferase (ALT) >1.5 x upper limit of normal (ULN);
- Aspartate aminotransferase (AST) >1.5 x ULN;
- Bilirubin (total) > 1.5 x ULN; and

During Run-in Period, participants will be dosed with 300 mg of allopurinol from Day -7 to Day -1. During the Treatment Period, participants will be administered 24 mg verinurad with 300 mg allopurinol once daily on Days 1 to 7.
During Run-in Period, participants will be dosed with 300 mg of allopurinol once daily from Day -7 to Day -1. During Treatment Period, participants will receive a single dose of 12 mg verinurad and 300 mg allopurinol on Day 1. No dosing will be done on Day 2. Participants will continue dosing on Day 3 and will be dosed once daily until Day 9.
During Run-in Period, participants in cohort 1 will receive placebo matching allopurinol capsule once daily from Day -7 to Day -1. During treatment period, participants in cohort 1 will receive placebo matching allopurinol capsule and placebo matching verinurad capsule once daily from Day 1 to Day 7.
