Efficacy and Safety of Extended Release and Immediate Release Febuxostat in Participants With Gout and Moderate Renal Impairment

Gout Clinical Trial

Official title: A Phase 2, Randomized, Double Blind, Multicenter, Placebo Controlled Study to Evaluate the Efficacy and Safety of Febuxostat 40 mg XR, 80 mg XR, 40 mg IR and 80 mg IR in Subjects With Gout and Moderate Renal Impairment

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of febuxostat 40 mg extended release (XR) and 80 mg XR in comparison with febuxostat 40 mg immediate release (IR) and 80 mg IR, respectively, in gout participants with moderate renal impairment.

Clinical Trial Description

The drug being tested in this study is called febuxostat. Febuxostat is being tested to decrease and maintain serum urate in people who have gout with moderate renal impairment. This study will look at serum urate levels in people who take febuxostat extended release (XR) capsules compared to febuxostat immediate release (IR) capsules and placebo.

The study will enroll approximately 200 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the five treatment groups—which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):

• Febuxostat 40 mg XR

• Febuxostat 80 mg XR

• Febuxostat 40 mg IR

• Febuxostat 80 mg IR

• Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient.

All participants will be asked to take one capsule at the same time each day throughout the study, and will be asked to call an interactive voice response system any time they are having a gout flare up. In addition to study medication, participants will also take 0.6 mg of colchicine every other day or naproxen 250 mg twice a day with lansoprazole 15 mg once a day to prevent gout flare ups.

This multi-center trial will be conducted in the United States. The overall time to participate in this study is up to approximately 4 months and participants will make up to 7 visits to the clinic. ;
