Primary Outcome Measures:
  • Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs) [ Time Frame: Baseline up to Week 288 ] [ Designated as safety issue: Yes ]
    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to the last participants visit in the study. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for safety evaluation.


Secondary Outcome Measures:

    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 and common activities over past week. Each item scored on 4-point scale, 0 to 3: 0=no difficulty; 1=some difficulty;2=much difficulty; 3=unable to do. Overall score was computed as sum of domain sc ores and divided by number of domains answered. Total possible score range 0-3: 0=least difficulty and 3=extreme difficulty. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for efficacy evaluations except for Modified Total Sharp Score (mTSS).

    mTSS = sum of erosion and Joint Space Narrowing (JSN) scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score). Change: scores at observation minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented potential improvement. Month 24 (the final visit) in Study A3921044 was taken as the first visit in current study.
