Evaluation of the Effectiveness and Safety of Two Dosing Regimens of Olokizumab (OKZ), Compared to Placebo and Adalimumab, in Subjects With Rheumatoid Arthritis (RA) Who Are Taking Methotrexate But Have Active Disease

The purpose of this study is to determine how safe and effective the study drug Olokizumab is, in patients with Rheumatoid Arthritis (RA) who are already receiving, but not fully responding to treatment with methotrexate (MTX).

   - Prior history of no response to hydroxychloroquine and sulfasalazine

   - Prior use of cDMARDs (other than MTX) within the following windows prior to baseline
   (cDMARDs should not be discontinued to facilitate a subject's participation in the
   study, but should instead have been previously discontinued as part of a subject's
   medical management of RA):

      1. 4 weeks for sulfasalazine, azathioprine, cyclosporine, hydroxychloroquine,
      chloroquine, gold, penicillamine, minocycline, or doxycycline

      3. History of untreated latent TB infection (LTBI), regardless of IGRA result at

      4. Positive interferon-gamma release assay (IGRA) result at Screening. If
      indeterminate, the IGRA can be repeated once during the Screening Period. If
      there is a second indeterminate result, the subject will be excluded.
