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-α 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-α antagonists at the dose listed above that reasonably results in the discontinuation of treatment with the TNF-α 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.

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
End of trial will be LPLV in follow-up phase which starts after patients complete: week 144; or week 24 evaluations if they either have rescue meds in the double-blind phase or discontinue from treatment for another reason during study. Patients will be followed up every 12 weeks until B cells, IgM and if appropriate IgG, return to LLN or baseline. CSR will be prepared based on the data through study week 144. An addendum will be prepared once all patients have completed the follow up period. |
