Gout, Hyperuricemia
Conditions
Brief summary
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.
