This single arm study will evaluate the long-term efficacy and safety of tocilizumab in patients who have completed treatment in the tocilizumab core studies of adults with rheumatoid arthritis. Patients will receive tocilizumab alone or in combination with standard anti-rheumatic treatment. The anticipated time on study treatment is 2+ years, and the target sample size is 500+ individuals.
