What was measured

Kaplan-Meier (KM) estimates of the time to first new flare and confidence intervals were determined. Participants met the definition of a new flare if they had: * Flare in joint, not a previously affected joint (at baseline or during study) * Flare in joint previously affected (at baseline or during study) after previous flare in joint has resolved completely. Participants did not meet the criterion of having a new gout flare if they had increasing/renewed gout pain in an affected joint before the flare had resolved completely.

Analysis population: The Full Analysis Set (FAS) consisted of all patients as randomized in the core study who had taken at least one dose of study drug.

Groups in this outcome

Canakinumab 150 mg

Participants received 1 subcutaneous (sc) injection of canakinumab 150 mg and 1 intramuscular (im) injection of placebo to triamcinolone acetonide on Day 1. Participants could receive a re-dose of study drug on demand upon the occurrence of new flares, but re-dosing could not occur until 14 days had elapsed after the previous dose. In the first extension study participants completing the 12 week core study could continue to be treated on demand with the same treatment for another 12 weeks for any new gout flare.

Triamcinolone Acetonide 40 mg

Participants received 1 intramuscular injection of triamcinolone acetonide 40 mg and 1 sc injection of placebo to canakinumab on Day 1. Participants could receive a re-dose of study drug on demand upon the occurrence of new flares, but re-dosing could not occur until 14 days had elapsed after the previous dose. In the first extension study participants completing the 12 week core study could continue to be treated on demand with the same treatment for another 12 weeks for any new gout flare.
