  Purpose

This is a comparative study of CP 690,550, Humira (adalimumab) and placebo on background methotrexate in patients with Rheumatoid Arthritis. The study is intended to provide evidence of the efficacy and safety of CP 690,550 when dosed 5 mg and 10 mg twice a day on background methotrexate in adult patients with moderate to severe Rheumatoid Arthritis. It is intended to confirm the benefits of CP-690,550 in improving signs and symptoms and physical function that were observed in Rheumatoid Arthritis. An active comparator, adalimumab, is also included.

    ACR20 response: greater than or equal to (>=) 20% improvement in tender joint count (TJC); >= 20% improvement in swollen joint count (SJC); and >= 20% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP). For comparison of CP-690,550 with placebo, placebo sequences were combined into single reporting group for Month 6 analysis.

  • Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) at Month 3 [ Time Frame: Baseline, Month 3 ] [ Designated as safety issue: No ]
    HAQ-DI: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; common activities over past week. Each item scored on 4-point scale from 0-3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as sum of domain scores and divided by number of domains answered. Total possible score range 0-3: 0=least difficulty and 3=extreme difficulty. For comparison of CP-690,550 with placebo, placebo sequences were combined into single reporting group for Month 3 analysis.

    DAS28-4 (ESR) calculated from SJC and TJC using 28-joint count, erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and patient's global assessment (PtGA) of disease activity (transformed score ranging 0 to 10; higher score indicated greater affectation due to disease activity). Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-4 (ESR) less than or equal to (<=) 3.2 implied low disease activity and > 3.2 to 5.1 implied moderate to high disease activity, and < 2.6 = remission. For comparison of CP-690,550 with placebo, placebo sequences were combined into single reporting group for Month 6 analysis.
