Brief summary:
This study will evaluate the efficacy and safety of ocrelizumab, compared with placebo, in combination with methotrexate in patients with active rheumatoid arthritis who are naive to methotrexate. Patients will be randomized to receive placebo, ocrelizumab 200mg i.v. or ocrelizumab 500mg i.v. on Days 1 and 15. Repeat courses of i.v. treatment will be administered at weeks 24, 52 and 76. All patients will receive concomitant methotrexate (7.5 mg escalating to 20mg p.o. weekly). The anticipated time on study treatment is 2+ years, and the target sample size is 500+ individuals.

Detailed description:

Arms:
arm 1: Participants received placebo intravenously on Days 1 and 15 and Weeks 24, 26, 52, 54, 76, and 78. Participants also received methotrexate 7.5 mg orally weekly starting on Day 1. The dose of methodrexate was increased to a dose of 20 mg per week by Week 8, administered in 1 dose or divided into 3 equal doses administered at 12-hour intervals. Participants also received folate ≥ 5 mg/week either as a single dose or as a divided weekly dose. Participants were also allowed to continue receiving background corticosteroid therapy, at a dose of ≤ 10 mg/day of prednisolone or prednisolone. arm 2: Participants received ocrelizumab 200 mg intravenously on Days 1 and 15 and Weeks 24, 26, 52, 54 and 76. Participants also received methotrexate 7.5 mg orally weekly starting on Day 1. The dose of methodrexate was increased to a dose of 20 mg per week by Week 8, administered in 1 dose or divided into 3 equal doses administered at 12-hour intervals. Participants also received folate ≥ 5 mg/week either as a single dose or as a divided weekly dose. Participants were also allowed to continue receiving background corticosteroid therapy, at a dose of ≤ 10 mg/day of prednisolone or prednisolone. arm 3: Participants received ocrelizumab 500 mg intravenously on Days 1 and 15 and Weeks 24, 26, 52, 54, and 76. Participants also received methotrexate 7.5 mg orally weekly starting on Day 1. The dose of methodrexate was increased to a dose of 20 mg per week by Week 8, administered in 1 dose or divided into 3 equal doses administered at 12-hour intervals. Participants also received folate ≥ 5 mg/week either as a single dose or as a divided weekly dose. Participants were also allowed to continue receiving background corticosteroid therapy, at a dose of ≤ 10 mg/day of prednisolone or prednisolone.
