• Available for assessments
• Polyarticular, pauciarticular or systemic disease onset
• Active polyarticular-course JRA with at least 5 swollen joints due to active arthritis (not bony overgrowth) and 3 joints with limitation of motion (LOM) at screening and the day 1 visit

• Stable doses of NSAIDS (including Cox-2 inhibitors e.g. celecoxib and rofecoxib) and systemic oral corticosteroids (= 10 mg/day or 0.2 mg/kg/day of prednisone; whichever was less) for 4 weeks before the first dose of anakinra and during the trial
• Subjects who received leflunomide must have completed the prescribed course of cholestyramine washout
