Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Improvement in Gout at 72 Hours Post-dose Using a Likert Scale72 hours

72 hours following treatment, patients were asked the question: "How would you rate the improvement in your gout since receiving the study medication?" Patients rated their improvement on the Likert 5-point scale: 1=Excellent, 2=Good, 3=Acceptable,4=Slight and 5=Poor. Improvement was assessed by determining patients who scored a "good" or "excellent" response.

Secondary Outcome Measures
NameTimeMethod
Non-inferiority of a Single Dose of Canakinumab Compared to Dexamethasone During Treatment Period72 hours
Time to Recurrence of the Symptoms of Acute Gout (if Applicable) During Treatment Period4 months

Time to recurrence is defined as from the point of improvement (good to excellent on Likert scale) to recurrence.

Time to Walk Independently (if Applicable) During Treatment Period4 months
Number of Participants With Discontinuation of Treatment Due to Adverse Events, Deaths or Serious Adverse Events During the Study4 months

Additional safety information can be found in the Adverse Event section.

Change in C-reactive Protein (CRP) From Baseline at Month 4Baseline, Month 4

Blood was collected at Baseline and Month 4 for CRP to identify the presence of inflammation, to determine its severity, and to monitor response to treatment. A negative change from baseline indicates improvement.

Change in Serum Amyloid A Protein (SAA) From Baseline at Month 4Baseline, Month 4

Blood was collected at Baseline and Month 4 for SAA to identify the presence of inflammation, to determine its severity, and to monitor response to treatment. A negative change from baseline indicates improvement.

ACZ885 (Canakinumab) Pharmacokinetics (PK) Serum Concentration During the Treatment PeriodBaseline, Days 0.25, 1, 3, 6, 20, 34, 55 and 119

Blood was collected for ACZ885 (canakinumab) levels at baseline and Days 0.25, 1, 3, 6, 20, 34, 55 and 119. Serum was analyzed by means of a competitive Enzyme linked immunosorbant assay (ELISA).

Change From Baseline in Pain Using a Visual Analog Scale at Month 4Baseline, Month 4

Patients rated their pain on a 100 millimeter (mm) visual analog scale, ranging from no pain (0) to unbearable pain (100). A negative change from baseline indicates improvement.

Number of Patients Who Took Rescue Medication4 months

Patients who did not improve by 72 hours post-dose (i.e. patients who show a pain Visual Analog (VAS) decrease of less than 50 % from baseline (Day 1, pre-dose) would have been treated with rescue medication of methylprednisolone 80 mg intravenous or intramuscular once at the discretion of the clinical investigator.
