Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics (PK) endpoints in terms of maximum observed concentration (Cmax) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Days 1, 8, 15 and 22
Cmax is the maximum observed concentration of a drug after administration
Days 1, 8, 15 and 22
PK endpoints in terms of area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint (AUC last) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Days 1, 8, 15 and 22
AUC last is the area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint
Days 1, 8, 15 and 22
PK endpoints in terms of area under the plasma concentration time curve from and from zero to infinity (AUC 0-∞) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Days 1, 8, 15 and 22
AUC 0-∞ is a meausre of total concentration from time zero to infinity
Days 1, 8, 15 and 22
PK endpoints in terms of time of occurrence of maximum observed concentration (tmax) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Days 1, 8, 15 and 22
Tmax is the time of occurrence of cmax
Days 1, 8, 15 and 22

Days 1, 8, 15 and 22

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of Adverse Events in terms of changes in laboratory parameters

Primary Completion (ACTUAL)

Primary Completion
