Primary Outcome Measures:
  • PK profile of lesinurad from plasma [ Time Frame: Day 1 and Day 5 ]
    PK endpoints in terms of maximum observed concentration (Cmax); time of occurrence of maximum observed concentration (Tmax); area under the plasma concentration time curve (AUC); and apparent terminal half-life (t1/2).


Secondary Outcome Measures:
  • Incidence of Adverse Events [ Time Frame: 5 weeks ]
    Changes in Laboratory, Electrocardiogram and Vital Signs Parameters

Detailed Description:
A change in manufacturing site of lesinurad tablets has been implemented. This study is intended to evaluate the clinical comparability of lesinurad tablets manufactured at the two different sites by assessing relevant clinical Pharmacokinetics (PK) parameters.
