What was measured

ACR50 or ACR70 response was defined as a ≥ 50% or 70% improvement compared with baseline in both tender joint count (TJC) \[68 joints\] and swollen joint count (SJC) \[66 joints\] as well as a ≥ 50% or 70% improvement in three of five additional measurements: 1) Physician's Global Assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\]; 2) Patient's Global Assessment of Disease Activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\]; 3) Patient's Assessment of Pain \[visual analog scale: 0=no pain to 100=unbearable pain\]; 4) Health Assessment Questionnaire \[20 questions, 8 components: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities, 0=without difficulty to 3=unable to do\] and 5) erythrocyte sedimentation rate.

Analysis population: Intent-to-treat population includes all participants randomized to Retreatment.

Groups in this outcome

Arm A: Rituximab Retreatment

1000 mg rituximab intravenous initial treatment on day 1 and day 15 plus 10-25 mg/week methotrexate followed by re-treatment during weeks 24 -40 consisting of two additional doses of 1000 mg rituximab 14 days apart plus 10-25 mg/week methotrexate.

Arm B: Placebo Retreatment

1000 mg rituximab initial treatment on day 1 and day 15 plus 10-25 mg/wk methotrexate followed by re-treatment during weeks 24 -40 consisting of two doses of placebo 14 days apart plus 10-25 mg/wk methotrexate.
