Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
DB; Adjusted Mean Change From Baseline to Day 197 in Disease Activity Score (DAS) 28 Score (Erythrocyte Sedimentation Rate [ESR]) For ABA Versus PLA (Last Observation Carried Forward [LOCF] Analysis)
Time Frame: Baseline (Day 1), 6 months (Day 197)
The DAS28 is a continuous disease measure which is a composite of 4 variables: the 28 tender joint count, the 28 swollen joint count, ESR or C-reactive protein (CRP), and participant assessment of disease activity measure on a visual analogue scale. The DAS28 has numeric thresholds that define high disease activity (> 5.1), low disease activity (< 3.2) and remission (< 2.6). A clinically significant response is a decrease in DAS28 score of >1.2 from baseline.

DB; DAS 28 (ESR) Area Under The Curve (AUC) Over 12 Months For ABA Versus INF
Time Frame: From Day 1 through Day 365 (12 months)
The DAS28 is a continuous disease measure which is a composite of 4 variables: the 28 tender joint count, the 28 swollen joint count, ESR or CRP, and participant assessment of disease activity measure on a visual analogue scale. The DAS28 has numeric thresholds that define high disease activity (> 5.1), low disease activity (< 3.2) and remission (< 2.6). Clinically significant response= decrease in DAS28 score of >1.2 from baseline. DAS28 AUC can be calculated from the DAS28 score versus time curve, which provides an assessment of changes in disease activity over time.

DB; Percentage of Participants With Clinically Meaningful Health Assessment Questionnaire-Disability Index (HAQ-DI) Response at Day 197
Time Frame: DB Day 197
The disability section of the full HAQ includes 20 questions to assess physical functions in 8 domains: dressing, arising, eating, walking, hygiene, reach, grip and common activities. The questions are evaluated on a 4-point scale: 0=without any difficulty, 1= with some difficulty, 2= with much difficulty, and 3= unable to do. Higher scores= greater dysfunction. A disability index was calculated by summing the worst scores in each domain and dividing by the number of domains answered. Clinically meaningful HAQ response=an improvement of at least 0.3 units from baseline in HAQ disability Index.

The cut-off value was 1.40 ug/mL; this was based on the mean (+ 3 SD) value in serum samples from 40 participants who had never received infliximab.
