Primary Outcome Measures:
  • Percentage of Participants Achieving 28 Joint Disease Activity Score (DAS28) Less Than or Equal to (≤) 3.2 at Week 88 [ Time Frame: Week 88 ] [ Designated as safety issue: No ]
    DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joint count (less than [<]20 percent [%] missing SJC or PJC was prorated), erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and Patient's General Health Visual Analog Scale (VAS). VAS is a line 0-100 millimeters (mm) in length; ranged from 0 (very well)-100mm (extremely bad). Participants placed a mark indicating their health over the previous 2-3 weeks. Higher scores indicated greater affectation due to disease activity. DAS28 ≤ 3.2 units equals (=) low disease activity.
