Study Arms:
- 1 (Type: EXPERIMENTAL): Treatment Arm A: Rilonacept (IL-1 Trap) at a dose of 2.2 mg/kg/wk (max 160 mg)given by subcutaneous injection for 3 months plus colchicine at a stable dose for those subjects already taking colchicine, or without colchicine for those intolerant or non-compliant with colchicine. Since the colchicine dose is stable throughout the study for each subject, at the prestudy dose, colchicine was not considered an intervention
- 2 (Type: PLACEBO_COMPARATOR): Treatment Arm B: Placebo given by subcutaneous injection weekly with or without colchicine for 3 months. Since the colchicine dose is stable throughout the study for each subject, at the prestudy dose, colchicine was not considered an intervention.

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