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.

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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • History of gout
  • sUA > 7 mg/dL
  • Estimated Glomerular Filtration Rate (eGFR) ≥ 30 mL/min/1.73m2

Exclusion Criteria:

  • Malignancy within 5 years, except for successfully treated basal or squamous cell carcinoma of the skin
  • History of cardiac abnormalities
  • History of kidney stones

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
Serum urate (uric acid) (sUA) level < 6 mg/dL following 6 weeks of dosing
Time Frame: 6 weeks
Comparison of the treatment groups for the proportion of patients with serum urate (uric acid) (sUA) level < 6 mg/dL following 6 weeks of dosing
6 weeks

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
Measure Description
Time Frame
sUA levels < 5, < 4, and < 3 mg/dL
Time Frame: 6 weeks
Comparison of the treatment groups for proportion of patients whose sUA levels are < 5, < 4, and < 3 mg/dL
6 weeks
Incidence of Adverse Events
Time Frame: 14 weeks
Treatment Emergent Adverse Events and Serious Adverse Event incidence.
14 weeks
Maximum Observed Plasma Concentration (Cmax)
Time Frame: 12 weeks
Plasma samples will be collected to assess plasma concentrations at a series of timepoints to derive Cmax.
12 weeks
Time to observed Cmax (Tmax)
Time Frame: 12 weeks
Plasma samples will be collected to assess plasma concentrations at a series of timepoints to derive Tmax.
12 weeks
Area under the plasma concentration-time curve (AUC)

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 16, 2021

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. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
November 17, 2022

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
