A Study to Assess the Efficacy, Safety, and Pharmacokinetics of ABP-671 in Patients With Gout or Hyperuricemia

April 10, 2023 updated by: Jiangsu Atom Bioscience and Pharmaceutical Co., Ltd.

A Randomized, Double-Blind, Dose-Ranging, Placebo-Controlled, Multicenter, Phase 2a Study to Assess the Efficacy, Safety, and Pharmacokinetics of ABP-671 Monotherapy in Patients With Gout or Hyperuricemia

This is a Phase 2a, multicenter, randomized, double-blind, placebo-controlled, dose-ranging study to evaluate the efficacy, safety, and pharmacokinetics study of 6 different dose regimens of ABP-671 compared with placebo. The study will consist of three sequential groups with escalating total daily ABP-671 doses. Each group is further divided into two dose cohorts with either QD or BID dosing. Each dose group will have 3 stages following screening: Run-in, Dose Evaluation, and Follow-up.

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

14 years to 71 years (Adult, Older Adult)

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
Time Frame
Mean percentage change in serum uric acid (sUA) levels
Time Frame: Baseline to the end of the 4-week Dose Evaluation Period
Baseline to the end of the 4-week Dose Evaluation Period

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.

Time Frame
Change in mean sUA
