Summary
This randomized, parallel-group, open-label study will evaluate the effect of Actemra (tocilizumab) on vaccination in patients with active rheumatoid arthritis who have an inadequate response to methotrexate and who have had an inadequate clinical response or were intolerant to treatment with one or more anti-tumor necrosis factor (anti-TNF) therapies.
