Primary Outcome Measures
NameTimeMethod
Number of Participants That Met Sustained Remission at Week 76 and Week 91 Based on DAS28 Score76 and 91 weeks

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.

Change From Baseline in Work Productivity and Activity Impairment (WPAI) Questionnaire: Percent Impairment While Working Due to Problem13, 26, 39, 52 weeks 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.
