Number of Participants That Met Sustained Remission at Week 76 and Week 91 Based on DAS28 Score
Sustained remission was defined as a DAS28 \<2.6 at the Week 76 and Week 91 visits without requiring a corticosteroid boost between the Week 52 and Week 64 visits, where the requirement for a corticosteroid boost was defined as a value of DAS28 \>3.2 at either the Week 56 or Week 64 visit. DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hour\]) and patient's global assessment (PGA) of disease activity. The participants who met sustained remission in both Week 76 and 91 are presented here.
Time frame: 76 and 91 weeks
Number of Participants Achieving Complete Response (Using Disease Activity Score Based on 28-joint Count, Modified Total Sharp Score, Health Assessment Questionnaire)
The composite measure of complete response over the last 3 months of Phase 1 was defined as: 1. DAS28 \<2.6 at the week 39 and 52 visits and, 2. No radiographic progression during Phase 1, defined as mean change in modified total Sharp score (mTSS) ≤0.5 and, 3. Health Assessment Questionnaire (HAQ) ≤ 0.5 at the week 39 and week 52 visits
Time frame: End of Phase 1
Change From Baseline in Modified Total Sharp Score (mTSS) at Week 52 and Final on Therapy
mTSS = sum of erosion and Joint Space Narrowing (JSN) scores for 44 joints (16 per hand and 6 per foot). mTSS scores ranged from 0 (normal) to 448 (worst possible total score). Change: scores at observation minus score at baseline. An increase in mTSS from 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 improvement.
Time frame: 52 week and Final on Therapy (includes all visits for a participant up to Week 52 or the visit they discontinued at)

WPAI:6 question participant rated questionnaire to determine the degree to which rheumatoid arthritis affected work productivity while at work and affected activities outside of work. Four scores are derived:percentage of absenteeism, percentage of presenteeism (reduced productivity while at work),overall work impairment score that combined absenteeism and presenteeism and percentage of impairment in activities performed outside of work. Scores scaled as 0 (not affected/no impairment) to 10 (completely affected/impaired). Higher scores indicated greater impairment and less productivity. The raw scores (0-10) are converted to percents (the variable is named "Percent impairment While Working") and as such range from 0 to 100.
Time frame: 13, 26, 39, 52 weeks and Final on Therapy (includes all visits for a participant up to Week 52 or the visit they discontinued at)

Work Productivity and Activity Impairment (WPAI) Questionnaire: Percent Work Time Missed in the Past 7 Days Due to Problem
WPAI: 6 question participant rated questionnaire to determine the degree to which rheumatoid arthritis affected work productivity while at work and affected activities outside of work. Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combined absenteeism and presenteeism and percentage of impairment in activities performed outside of work. Scores scaled as 0 (not affected/no impairment) to 10 (completely affected/impaired). Higher scores indicated greater impairment and less productivity. The raw (0-10) scores are converted to percents (the variable is named "Percent impairment While Working") and as such range from 0 to 100.
