Study Design:

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Outcome Measure:

Number of Participants in DAS 28 C-reactive Protein (CRP) Remission at Month 12

Outcome Description:

Number of participants who achieved remission at Month 12 of treatment, as defined by a Disease Activity Score (DAS) 28-CRP score of <2.6. DAS 28-CRP is a continuous measure, a composite of 4 variables: number of tender joints out of 28 joints, number of swollen joints out of 28 joints, CRP (in mg/L), and subject assessment of disease activity measure on a Visual Analogue Scale (VAS) of 100 millimeters (mm). The DAS28 scale=0 (best) to 10 (worst), indicating the current activity of the rheumatoid arthritis. A DAS28 >5.1 = high disease activity; <=3.2 = low disease activity; <2.6 = remission.
