This is a randomized, placebo controlled, double-blind study with two separate cohorts to assess safety, tolerability and pharmacokinetics of verinurad and allopurinol in healthy subjects. In cohort 1, twelve Asian subjects will be treated with allopurinol 300mg for 7 days followed by either allopurinol 300mg and verinurad 24mg or matching placebo for 7 days. In Cohort 2, nine Chinese subjects will be treated with allopurinol 300mg for 7 days followed by allopurinol 300mg and verinurad 12mg administered on 7 out of 8 days.
