Inclusion Criteria

1) Age > or equal 18 years 2) A diagnosis of rheumatoid arthritis according to the American College of Rheumatology (ACR1987 classification) of at least six months? duration from diagnosis at screening 3) Active disease at the time of screening as defined by: > or equal 8 swollen joints (of 66 joints assessed) and > or equal 8 tender joints (of 68 joints assessed) and C-Reactive Protein (CRP) > or equal 1.0 mg/dL or Erythrocyte Sedimentation Rate (ESR) > or equal 22 mm/hour (using Becton Dickinson Seditainer) and DAS28 > or equal 3.2 (based on ESR) Note: The swollen and tender joints must be reassessed at baseline (Visit 2) to ensure these eligibility criteria are fulfilled prior to randomization. Where possible joint count reassessment must be performed at the baseline visit (Visit 2); if this is not possible it can be performed < o equal 3 days prior to Visit 2. 4) RA functional class I, II or III 5) Inadequate response to previous or current > or equal antagonist treatment after infliximab therapy (> or equal mg/kg; at least 4 infusions), or adalimumab therapy (40 mg every other week for > or equal 3 months), or etanercept therapy (25 mg twice weekly or 50 mg once a week for > or equal 3 months) defined as: Inadequate efficacy according to the investigator?s judgment and/or Intolerance defined as one or more side effects following at least one administration of one of the TNF alfa antagonists at the dose listed above that reasonably results in the discontinuation of treatment with the TNFalfa antagonist treatment 6) Treatment with methotrexate (MTX), 7.5-25 mg/week, for at least 12 weeks and at a stable dose for at least 4 weeks prior to Visit 2.
