What was measured
The DAS28 score is a measure of the patient's disease activity calculated using the tender joint count (TJC) \[28 joints\], swollen joint count (SJC) \[28 joints\], patient's global assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\] and the erythrocyte sedimentation rate (ESR) for a total possible score of 2 to 10. Higher values indicate higher disease activity. A negative change from baseline indicates improvement.
Analysis population: Participants from the Intent-to-treat population, that includes all participants randomized to Retreatment, with data available for analyses.
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.
