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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Gout subjects meeting 2015 ACR/EULAR Gout Classification Criteria with inadequate urate-lowering response
  • Subject has had at least 2 gout flares in the previous 12 months.
  • Body Mass Index (BMI) between 18.0 and 45.0 kg/m2 (inclusive).
  • Male and Female Subjects must agree to abstain or use effective contraception methods from the time of signing ICF and for the duration of study participation through 30 days after the last dose of study drug.
  • Subjects must have adequate clinical laboratory and ECG results as assessed by the Principal Investigator

Exclusion Criteria:

  • Subjects with significant comorbidities, inadequate lab function, current (and within the past 5 years) diagnosis of cancer or any condition that, in the judgment of the investigator, would place him/her at undue risk, or potentially compromise the results or interpretation of the study.
  • Women who are pregnant or breastfeeding

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.
