Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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 and 200/200 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Days 1 and Day 8
Cmax is the maximum observed concentration of a drug after administration
Days 1 and Day 8
PK endpoints in terms of time of occurrence of maximum observed concentration (tmax) for lesinurad/allopurinol 200/300 and 200/200 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Day 1 and Day 8
Tmax is the time of occurrence of cmax
Day 1 and Day 8
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 and 200/200 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Day 1 and Day 8
AUC last is the area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint
Day 1 and Day 8
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 and 200/200 FDC tablets relative to lesinurad and allopurinol monocomponent tablets
Time Frame: Day 1 and Day 8
AUC 0-∞ is a meausre of total concentration from time zero to infinity
Day 1 and Day 8

Time Frame: Day 1 and Day 8
t1/2 is a measure of apparent terminal half-life
Day 1 and Day 8

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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
