This study will assess the long-term safety and efficacy of repeat treatment courses of rituximab, in combination with methotrexate in a disease-modifying anti-rheumatic drug (DMARD) inadequate responder population of participants who were previously randomized into studies WA16291 (NCT02693210) or WA17043/U2644g (NCT00074438). The study permits multiple re-treatments until the protocol-defined end-of-treatment date (31 December 2011). Participants will then enter a safety follow-up (SFU) period of at least 48 weeks. This will provide at least 7 years follow-up data on all participants initially randomized into WA16291 or WA17043/U2644g. Approximately 600 participants will potentially be eligible to enter this open label extension study from their respective feeder studies.

  1. description
    Participants will receive rituximab 1 gram intravenously (IV) on Days 1 and 15 of each course of retreatment. In addition, participants will receive methotrexate 10-25 milligrams per week (mg/week) orally or parenterally, methylprednisolone 100 mg IV 30 minutes prior to both rituximab infusions, and a stable dose of folic acid greater than or equal to (\>=) 5 mg/week or equivalent. Participants will receive 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 will be 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 will be continued until withdrawal of consent or study treatment completion on 31 December 2011, whichever is sooner.

    The ACRn is calculated for each participant by taking the lowest percentage improvement in (1) SJC or (2) TJC or (3) the median of the remaining 5 components of the ACR response (patient's assessment of disease activity; patient's global assessment of pain; physician's assessment of disease activity; participant's assessment of physical function; an acute phase reactant value \[either CRP or ESR\]). The index of improvement in RA, where 0 indicates no improvement and 100 indicates a 100% improvement across all signs and symptoms of RA.

The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders had a change from baseline greater than (\>) 1.2 with a DAS28 score less than or equal to (≤) 3.2; moderate responders had a change from baseline \>1.2 with a DAS28 score \>3.2 to less than or equal to (≤) 5.1 or a change from baseline \>0.6 to ≤1.2 with a DAS28 score ≤5.1.
