1) Age = 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:
= 8 swollen joints (of 66 joints assessed)
and
= 8 tender joints (of 68 joints assessed)
and
C-Reactive Protein (CRP) = 1.0 mg/dL or Erythrocyte Sedimentation Rate (ESR) = 22 mm/hour
and
DAS28=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 = 3 days prior to Visit 2.
4) RA functional class I, II or III
5) Inadequate response to previous or current TNF-a antagonist treatment after infliximab therapy (=3 mg/kg; at least 4 infusions), or adalimumab therapy (40 mg every other week for =3 months), or etanercept therapy (25 mg twice weekly or 50 mg once a week for =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-a antagonists at the dose listed above that reasonably results in the discontinuation of treatment with the TNF-a 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. Doses of MTX as low as 7.5 mg per week are permitted for patients who can not tolerate higher doses
7) Following receipt of verbal and written information about the study, the patient must provide signed informed consent before any study related activity including wash-out of other drug products is carried out
France: In France, a patient will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.

- Cervical carcinoma Stage 1B or less
- Non-invasive basal cell and squamous cell skin carcinoma
- Other cancer with complete response duration of > 5 years
11) Chronic or ongoing active infectious disease requiring systemic treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis and active hepatitis B and C
12) Clinically significant cardiac disease including unstable angina, acute myocardial infarction within six months from screening, congestive heart failure, known QT abnormalities, and arrhythmia requiring therapy, with the exception of extra systoles or minor conduction abnormalities
