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

A Multicenter, Open-Label Long-Term Extension Study of WA22762 to Evaluate Safety and Efficacy of Subcutaneous Tocilizumab in Patients With Moderate to Severe Rheumatoid Arthritis

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.

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
• Oral corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDS) up to the recommended dose are permitted if on stable dose regimen for greater than and equal to (>/=) 4 weeks prior to baseline
• Permitted non-biological disease-modifying anti-rheumatic drugs (DMARDs) are allowed

Exclusion Criteria:

• Participants who have prematurely withdrawn from the WA22762 LTE study for any reason
• Previous treatment with any cell-depleting therapies, including investigational agents or approved therapies
• Treatment with an anti-tumor necrosis factor (TNF) or anti-interleukin (IL) 1 agent, or a T-cell co stimulation modulator since the last administration of study drug in the WA22762 LTE study
• 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
• Uncontrolled disease states, such as asthma or inflammatory bowel disease, where flares are commonly treated with oral or parenteral corticosteroids
• Evidence of serious uncontrolled concomitant disease
• Known active current or history of recurrent infection
• Primary or secondary immunodeficiency (history of or currently active)
• Body weight >150 kilograms (kg)
• Pregnant or lactating women
• Inadequate hematologic, renal or liver function
• History of alcohol, drug or chemical abuse within 1 year prior to screening
