Phase II Dose Finding Study of RDEA3170 Versus Placebo in Japanese Patients With Gout or Asymptomatic Hyperuricemia

August 21, 2019 updated by: AstraZeneca

A Randomized, Double-Blind, Multicenter, Placebo-Controlled, Parallel Group, 24-Week Phase II Study to Evaluate Efficacy and Safety of RDEA3170 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg Versus Placebo and Open-Label Allopurinol 200 mg as a Reference Arm in Japanese Patients With Gout or Asymptomatic Hyperuricemia

This study is to examine the hypothesis that administration of RDEA3170 to Japanese patients with gout or asymptomatic hyperuricemia in doses of 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg once daily, respectively will result in greater reduction of sUA compared to placebo.

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

20 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Percent Changes of Serum Uric Acid Levels From Baseline Levels
Time Frame: Baseline and Week 16
The primary objective of the study is to compare percent changes of serum uric acid levels from baseline levels after 16 weeks of dosing between RDEA3170 treatment groups and the placebo treatment group.
Baseline and Week 16

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.
