Summary:

      This multi-center, open-label single arm Phase IIIb study will evaluate the safety and
      efficacy of subcutaneous (SC) tocilizumab administered as monotherapy and/or in combination
      with methotrexate or other non-biologic disease modifying antirheumatic drugs (DMARDs) in
      participants with rheumatoid arthritis (RA) with an inadequate response to non-biologic
      DMARDs.
