Inclusion Criteria

To be eligible for this trial, patients must meet all of the following criteria:

1. Completed the 24-week MA21573 core study, had at least a moderate response (EULAR definition criteria Appendix 7) and no AEs, SAEs or conditions that lead to unacceptable risk of continued treatment. Patients should be scheduled to receive the first tocilizumab (TCZ) infusion in MA22460 between 4 and 6 weeks after the last TCZ infusion in the core study.
2. Willing to give written informed consent for participation in the extension study
3. Able and willing to comply with the requirements of the extension study protocol
4. If female and of child-bearing potential, the patient must have a negative urine pregnancy test at Day 1 before the infusion takes place.

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes

Exclusion Criteria

Patients with any of the following criteria will not be eligible to participate in the study:

Disease:
1. Functional class IV as defined by the ACR Classification of Functional Status in RA (largely or wholly incapacitated with patient bedridden or confined to wheel chair, permitting little or no self-care).

Laboratory analyses (at transition from core study):
Lab values from the Week 20 visit of the core study are to be used for the determination of the patient’s eligibility for MA22460. If the patient is not eligible based on Week 20 laboratory values, the sample from Week 24 can be used. Therefore a delay of the study infusion will be permitted until the laboratory results are available.Study drug administration can occur on the week 24 visit which is then Day 1 of this study. In case that the drug administration needs to be delayed for any other reasons, and study drug administration will not occur at the Week 24 visit, it can be delayed by a maximum of 2 weeks. Day 1 is defined as the day of the first study drug administration under MA22460.

2. Serum creatinine > 142 µmol/L (1.6 mg/dL) in female patients and > 168 µmol/L (1.9 mg/dL) in male patients and no active renal disease
3. ALT (SGPT) or AST (SGOT) = 3 ULN
4. Platelet count < 100 x 10^9/L (100,000/mm^3)
5. Hemoglobin < 85 g/L (8.5 g/dL; 5.3 mmol/L)
6. WBC < 1.0 x 10^9/L (1000/mm^3), ANC < 1 x 10^9/L(1000/mm^3)
7. Absolute lymphocyte count < 0.5 x 10^9/L (500/mm^3)
8. Known positive hepatitis B surface antigen or hepatitis C antibody
9. Total bilirubin > ULN
10. Triglycerides > 10 mmol/L (> 900 mg/dL) at inclusion in extension study
