- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Core Study:~Inclusion criteria:~* Meeting the American College of Rheumatology (ACR) 1977 preliminary criteria for the classification of acute arthritis of primary gout~* Onset of current acute gout flare within 5 days prior to study entry~* Baseline pain intensity ≥ 50 mm on the 0-100 mm visual analog scale (VAS)~* History of ≥ 3 gout flares within the 12 months prior to study entry~* Contraindication, intolerance, or lack of efficacy for non-steroidal anti-inflammatory drugs (NSAIDs) and/or colchicine~Exclusion criteria:~* Rheumatoid arthritis, evidence/suspicion of infectious/septic arthritis, or other acute inflammatory arthritis~* Presence of severe renal function impairment~* Use of specified pain relief medications or biologics ( corticosteroids, narcotics, paracetamol/acetominophen, ibuprofen, colchicine, IL-blocker, and tumor necrosis factor inhibitor) within specified periods prior to study entry~* Live vaccinations within 3 months prior to randomization~* Requirement for administration of antibiotics against latent tuberculosis (TB)~* Refractory heart failure (Stage D)~* Unstable cardiac arrhythmias or unstable symptomatic coronary ischemia~* Any active or recurrent bacterial, fungal, or viral infection~Extension Study 1:~Inclusion Completion of the Core study. A patient was defined as completing the core study if they completed the study up to and including visit 7.~Exclusion~- Continuation in this extension study was considered inappropriate by the treating physician.~Extension Study 2:~Inclusion Completed of the first extension study CACZ885H2356E1. A patient was defined as completing the first extension study if they completed the study up to and including Visit 10).~Exclusion~-Continuation in this extension study was considered inappropriate by the treating physician~Other protocol-defined inclusion-exclusion criteria applied to the core and extension studies.

Study Arms:
- Canakinumab 150 mg (Type: EXPERIMENTAL): Patients received 1 subcutaneous (sc) injection of canakinumab 150 mg and 1 intramuscular (im) injection of placebo to triamcinolone acetonide on Day 1. Patients could receive re-dose of study drug on demand upon occurrence of new flares, but re-dosing could not occur until 14 days had elapsed after previous dose. Patients completing 12 weeks core study were allowed to continue treatment in another 12-week extension for any new gout flare on demand with same treatment as assigned in core study.~After completing the first extension, patients were offered to enter second extension study, whereby all patients were treated open-label on demand with canakinumab 150 mg sc upon new flare for 1 year for a total duration of 18 months following randomization in core study. Patients completing first 12 weeks extension study were allowed to continue to be treated in another single-arm, open-label 48 weeks extension when all patients from both treatment arms received canakinumab on demand
- Triamcinolone acetonide 40 mg (Type: ACTIVE_COMPARATOR): Patients received 1 intramuscular (im) injection of triamcinolone acetonide 40 mg and 1 subcutaneous (sc) injection of placebo to canakinumab on Day 1. Patients 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. Patients completing the 12 weeks core study were allowed to continue to be treated in another 12 weeks extension study for any new gout flare on demand with the same treatment as assigned in the core study.~Patients under this arm who agreed to continue to 2nd extension period of 12 months, were switched to canakinumab 150 mg sc for any new gout flare during this period Triamcinolone acetonide was not to be administered in the 48-week session.

Based on this trial design, predict the completion outcome and termination type (if applicable).
