A Long-Term Extension Study of WA22762 to Evaluate Safety and Efficacy of Subcutaneous Tocilizumab in Participants With Moderate to Severe Rheumatoid Arthritis (RA).

This multicenter, open-label, single arm, interventional, long-term extension (LTE) study will evaluate the safety and efficacy of tocilizumab (TCZ, RoActemra/Actemra) in French participants with moderate to severe RA who have completed the Week 97 visit of WA22762 LTE study (NCT01194414) (EudraCT Number 2010-018375-22). Participants from France, who completed the Week 97 visit of the WA22762 LTE study and considered as responders (defined as having improvement in disease activity score based on 28-joint count \[DAS28\] of greater than \[\>\] 1.2 points) will continue TCZ treatment within this local LTE study for a maximum of 156 weeks of subcutaneous (SC) TCZ treatment, or until SC TCZ becomes commercially available, whichever occurs first.


Eligibility Criteria:
Inclusion Criteria:

* Negative pregnancy test at screening and baseline
* Participants who have completed the 97-week WA22762 LTE study on SC or intravenous (IV) TCZ and who experienced, at any time during WA22762, clinically significant improvement in DAS28 (\>1.2 points), and based on the investigator's judgment may continue to benefit from TCZ treatment in this study investigating the SC formulation
* No current or recent adverse events or laboratory findings preventing the use of the study drug dose of TCZ 162 mg SC at baseline visit
* Receiving treatment on an outpatient basis
* Females of childbearing potential and males with female partners of childbearing potential must agree to use reliable means of contraception during the study and for at least 3 months following the last dose of study drug

* Immunization with a live/attenuated vaccine since the last administration of study drug in the WA22762 LTE study
* Diagnosis, since last WA22762 visit (Week 97), of rheumatic autoimmune disease other than rheumatoid arthritis; secondary Sjörgen's syndrome with RA is permitted
* Diagnosis, since last WA22762 visit (Week 97), of inflammatory joint disease other than RA
