What was measured
ACR50 was defined as an overall score of 50 in the ACRn calculation. Overall score defined as lowest percent improvement from BL of following 3 measures: TJC (68 joints), SJC (66 joints), and the 3rd lowest improvement achieved by at least 3 of 5 remaining ACR core parameters: physician's global assessment of disease activity, participant's global assessment of disease activity, participant's assessment of pain (VAS), HAQ, and CRP. If CRP missing, ESR was used. In order for improvements in the ACRn score to be expressed as a positive result, rather than the negative changes that improvements represent, the final ACRn results were multiplied by negative 1. LOCF for TJC/SJC, HAQ, CRP/ESR, VAS. If change in CRP incalculable, change in ESR used. ACR50 set to Non-Responder if ACRn missing.
Analysis population: ITT-M2 population
Groups in this outcome
Rituximab Low Dose + Methotrexate
Participants received rituximab, 0.5 g, IV, on Days 1, 15, 168, and 182. Participants also received methylprednisolone 100 mg, IV, by slow infusion, which was completed at least 30 minutes prior to each infusion of rituximab Days 1, 15, 168, and 182. Participants also received methotrexate 10-25 mg/mL, PO or parenterally, as prescribed by the treating physician and in accordance with the local label. Participants also received a stable dose of folate ≥ 5 mg/week given either as a single dose or as a divided weekly dose.
Rituximab Escalated Dose + Methotrexate
Participants received rituximab, 0.5 g, IV, on Days 1 and 15 and 1.0 g, IV, on Days 168 and 182. Participants also received methylprednisolone 100 mg, IV, by slow infusion, which was completed at least 30 minutes prior to each infusion of rituximab Days 1, 15, 168, and 182. Participants also received methotrexate 10-25 mg/mL, PO or parenterally, as prescribed by the treating physician and in accordance with the local label. Participants also received a stable dose of folate ≥ 5 mg/week given either as a single dose or as a divided weekly dose.
Rituximab High Dose + Methotrexate
Participants received rituximab, 1.0 g, IV, on Days 1, 15, 168, and 182. Participants also received methylprednisolone 100 mg, IV, by slow infusion, which was completed at least 30 minutes prior to each infusion of rituximab Days 1, 15, 168, and 182. Participants also received methotrexate 10-25 mg/mL, PO or parenterally, as prescribed by the treating physician and in accordance with the local label. Participants also received a stable dose of folate ≥ 5 mg/week given either as a single dose or as a divided weekly dose.
