What was measured

A participant had an ACR20 response if there was at least a 20 percent (%) improvement, ie, reduction from Baseline, in tender joint count (TJC) and swollen joint count (SJC) (28 assessed joints) and in at least 3 of the following 5 parameters: 1) Physician's Global Assessment of Disease Activity \[visual analog scale (VAS): 0=no disease activity to 100=maximum disease activity\]; 2) Patient's Global Assessment of Disease Activity \[VAS: 0=no disease activity to 100=maximum disease activity\]; 3) Patient's Assessment of Pain \[VAS: 0=no pain to 100=unbearable pain\]; 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) an acute-phase reactant (either C-reactive protein \[CRP\] or erythrocyte sedimentation rate \[ESR\]). The ACR20 response was compared to Baseline in the precursor studies WA16291 or WA17043.

Analysis population: Intent to treat (ITT) Population included all participants who received any part of an infusion of study medication under Study WA16855. Here, number of participants analyzed = participants who were evaluable for this outcome.

Groups in this outcome

Rituximab

Participants received rituximab 1 gram IV on Days 1 and 15 of each course of retreatment. In addition, participants received methotrexate 10-25 mg/week orally or parenterally, methylprednisolone 100 mg IV 30 minutes prior to both rituximab infusions, and a stable dose of folic acid \>=5 mg/week or equivalent. Participants received retreatment (next course of rituximab repeat treatment) within 2 weeks of meeting the retreatment criteria as defined in the protocol (minimum of 24 weeks after the first \[Day 1\] infusion of the last course of rituximab). Repeat treatment was based on the investigator's decision of prior clinical response to rituximab, clinical need and evidence of active disease (Disease Activity Score in 28 joints \>=2.6). Retreatment with rituximab was continued until withdrawal of consent or study treatment completion on 31 December 2011, whichever occurred earlier.
