Patients with a history of immunization for Influenza (within past 12 months) and Pneumococcal vaccination (within 4 years) were included. If not already immunized, vaccination was completed when medically indicated (only during flu season for influenza) and such patients were included after approximately a 3 week window post-immunization to allow immunity to develop for vaccine.~10.

Disease activity criteria of ≥6 out of 28 tender joints and ≥6 out of 28 swollen joints.~2. One of the following also had to be present:~   1. High-sensitive C-Reactive Protein (hsCRP) concentration ≥10 mg/L~  2. Erythrocyte Sedimentation Rate (ESR) ≥28 mm/1st hr~  3. a. + b. based on screening values.~EXCLUSION~1. History of hypersensitivity to study drug or to molecules with similar structures.~2. Any therapy by intra-articular injections (e.g. corticosteroid) required for treatment of acute RA flare within 4 weeks before randomization.~3. Current use of DMARDs other than MTX. DMARDs included but were not limited to: biologic agents, thiolates (D-penicillamine, thiopronine), sulfasalazine, gold compounds, antimalarials, cyclosporine A, azathioprine, leflunomide, and alkylating agents such as cyclophosphamide.~4. If a patient had been discontinued from DMARDs, the patient should have been off the agent for at least 4 weeks, except leflunomide which was 8 weeks.~5. Patients with evidence of active pulmonary disease (e.g. tuberculosis, fungal diseases).~6. Donation or loss of 400 mL or more of blood within 8 weeks prior to dosing.~7. Who had a live vaccination within 12 weeks before randomization, or were planning to have one during the study and were not willing/able to postpone until study completion.~8. a) With bacterial, fungal or viral infections at the time of enrollment, including patients with evidence of human immunodeficiency virus (HIV) infection, hepatitis B and hepatitis C infection.~   b) History of a positive purified protein derivative (PPD) of tuberculin skin test without a follow-up of a negative chest X-ray.~   c) Patients requiring administration of antibiotics against latent tuberculosis, e.g. isoniazide.~9. Underlying metabolic, hematologic, renal, hepatic, infectious or gastrointestinal conditions which in the opinion of the investigator immunocompromised the patient and/or placed the patient at unacceptable risk for participation in an immunomodulatory therapy. In particular, clinical evidence or history of multiple sclerosis or other demyelinating diseases, or Felty's syndrome.~10. With significant medical problems, including but not limited to the following: uncontrolled hypertension (≥160/95 mmHg), congestive heart failure, type-I-diabetes(well controlled type-II-diabetes was allowed even when requiring insulin), thyroid disease (unless the patient was taking a stable dose of thyroid hormone for at least 12 weeks before randomization).~11. Other rheumatic diseases that could confound the evaluation of efficacy, including but not limited to primary fibromyalgia, ankylosing spondylitis, Lyme disease, adult juvenile RA, systemic lupus erythematosus, gout and pseudo gout, vasculitis, psoriatic arthritis, reactive arthritis, primary Sjoegren's Syndrome, and Behcet's Syndrome.~12. Any medical or psychiatric condition which, in the Investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol.~13. History of malignancy of any organ system, treated or untreated, within the past 5 years (with the exception of adequately treated basal cell carcinoma or squamous-cell carcinoma of the skin, carcinoma in situ of the cervix, colon polyps with non-invasive malignancy that have been removed).~14. Use of any investigational drug other than RA therapy and/or devices at the time of randomization, or within 30 days or 5 half- lives of randomization, whichever was longer.~STUDY EXTENSIONS~Extension Studies Inclusion Criteria:~1. Patients who completed the core CACZ885A2201 study may enter the first extension study upon signing informed consent. A patient is defined as completing the study if he/she completed the core CACZ885A2201 study up to and including Visit 12.~2. Patients who completed the first extension study, may enter the second.~Extension Studies Exclusion Criteria~1. Patients for whom continued treatment in the extension is not considered appropriate by the treating physician.~2. Patients who were non-compliant or who demonstrated a major protocol violation in the core CACZ885A2201 study.~3. Patients who discontinued from the core CACZ885A2201 study before Visit 12.
