Arthritis, Rheumatoid
Conditions
Brief summary
This multicenter, open-label, single-arm extension study will evaluate the long-term safety of tocilizumab (RoActemra/Actemra) in participants with RA. Participants who have completed the MA21488 (NCT00810199) core study and the ML21530 (NCT00754572) study and who could benefit from the study drug, according to the opinion of the investigator, will receive 8 milligrams per kilogram (mg/kg) of intravenous (IV) tocilizumab every 4 weeks. The anticipated time on study treatment is 104 weeks.
Interventions
DMARDs may be added to the tocilizumab treatment in any visit, at the discretion of the investigator, according to the local prescription information and participant's tolerance. Study protocol does not specify any particular DMARD.
Tocilizumab will be administered at 8 mg/kg IV dose every 4 weeks for 104 weeks

Health Assessment Questionnaire (HAQ) Pain VAS Score
The HAQ pain VAS is a measure of pain on a continuous 100 mm scale. Participants were asked to indicate how much pain they had in the past week as a result of their illness on a horizontal line from 0 (no pain) to 100 mm (severe pain).
Time frame: Baseline, Weeks 12, 24, 36, 48, 56, 68, 80, 92, 104, and FU Visit 1 (Week 108), FU Visit 2 (Week 116)

Participant's Pain Assessment Using VAS Score
Participant's pain assessment was made on a horizontal 0-100 mm VAS, with 0 mm (left end of the line) described as no pain and 100 mm (right end of the line) as unbearable pain. The participant marked the line according to their assessment and the distance from the left edge was measured.
Time frame: Baseline, Weeks 12, 24, 36, 48, 56, 68, 80, 92, 104, and FU Visit 1 (Week 108), FU Visit 2 (Week 116)
