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.
