Double Blind Phase: Change From Randomization in Disease Activity Score in 28 Joints Using 4 Variables (DAS28-4) (Erythrocyte Sedimentation Rate [ESR]) at Week 48
DAS28 is a measure of disease activity in participants with rheumatoid arthritis. DAS28-4 (ESR) was calculated from swollen joint count (SJC) and tender/painful joint count (TJC) using 28 joints count, ESR (millimeters per hour \[mm/hr\]) and participant global assessment of arthritis (PtGA) on a 100 millimeter (mm) visual analog scale (VAS: scores ranging from 0 mm \[very well\] to 100 mm \[worst\], higher scores indicate worse health condition). Total DAS28-4 (ESR) score range: 0 (none) to 9.4 (extreme disease activity), higher score indicated more disease activity. DAS28-4 (ESR) less than or equal to (\<=) 3.2 implied low disease activity and greater than (\>) 3.2 to \<=5.1 implied moderate disease activity, \>5.1 implied high disease activity, and DAS28-4 (ESR) less than (\<) 2.6 implied remission. DAS28-4 (ESR) = 0.56\*sqrt(TJC28) + 0.28\*sqrt(SJC28) + 0.70\*In(ESR in mm/hour) + 0.014\*PtGA in mm; ln = natural logarithm, sqrt = square root of.

Double Blind Phase: Change From Randomization in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Weeks 36 and 48
HAQ-DI assesses the degree of difficulty a participant has experienced during the past week in 8 domains of daily living activities: dressing/grooming; arising; eating; walking; reach; grip; hygiene; and other activities.. There were total of 30 items distributed in these 8 domains. Each item was scored on a 4-point scale from 0 to 3: 0= no difficulty; 1= some difficulty; 2= much difficulty; 3= unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered.

Double Blind Phase: Change From Randomization in the Short Form 36 (SF-36) Health Survey 8 Domain Scores at Weeks 36 and 48
SF-36 is a participant reported standardized survey designed to assess generic health related quality of life. It consisted of 36 items evaluating 8 aspects of functional health and well-being: physical functioning, role physical, bodily pain, social functioning, mental health, role emotional, vitality, and general health perception. The score range for each of the 8 health aspects was from 0 (poor health) to 100 (better health), higher scores indicating good health condition. Scores of 8 health aspects were summarized to derive the 2 component scores (physical component scores \[PCS\], mental component scores \[MCS\]) ranging from 0 (worst) to 100 (best), where higher PCS/MCS indicated good health condition.
