Study Summary

This purpose of this clinical research was to determine the efficacy and safety of an experimental drug called Rilonacept in participants with an acute gout attack. Participants participated in this study for 30 days. Rilonacept alone was being compared with Indomethacin alone and the combination of Rilonacept plus Indomethacin in treating acute gout flares.

Change in PAP-LS in the index joint from baseline (Day 1) to the averaged PAP-LS values at 24, 48 and 72 hours was reported in this outcome measure (averaged PAP value= \[PAP at 24 hours + PAP at 48 hours + PAP at 72 hours\]/3).
