Measure
Tocilizumab
Participants received tocilizumab 8 milligrams per kilogram (mg/kg) intravenous infusion once every 4 weeks, for a total of 6 infusions during the initial phase of the study. Participants who completed the initial phase and had at least one moderate response according to the European League Against Rheumatism (EULAR) category entered the extension phase and received an additional 6 infusions of 8 mg/kg tocilizumab every 4 weeks.

Timeframe: Weeks 4, 8, 12, 16, 20, 24, 36, 48 and 52

Population: Safety population; number (n)= number of participants analyzed at a specific visit

DAS28 calculated from the swollen joint count (SJC) and tender joint count (TJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hour\]) and participant's global assessment (PtGA) of disease activity by Visual analog Scale (VAS; participant rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). DAS28 less than or equal to (≤) 3.2 equals (=) low disease activity (LDA), DAS28 greater than (\>) 3.2 to 5.1 = moderate to high disease activity. A reduction of at least 1.2 units in DAS28 was considered clinically significant improvement.

The participants assessed their pain using a 0 to 100 millimeter (mm) horizontal VAS. The left-hand extreme of the line equals 0 mm, and is described as "no pain" and the right-hand extreme equals 100 mm as "unbearable pain". The participants marked the line corresponding to their level of pain and the distance from the left edge was measured.

The participant's global assessment of disease activity was assessed using a 0 to 100 mm horizontal VAS by the participant. The left-hand extreme of the line equals 0 mm, and is described as "no disease activity" (symptom-free and no arthritis symptoms) and the right-hand extreme equals 100 mm, as "maximum disease activity" (maximum arthritis disease activity). The participants marked the line corresponding to their assessment of disease activity and the distance from the left edge was measured.

Population: Safety population; n=number of participants assessed for the given parameter at the specified timepoint.

The physician's global assessment of disease activity was assessed using a 0 to 100 mm horizontal VAS by the physician. The left-hand extreme of the line equals 0 mm, and is described as "no disease activity" (symptom-free and no arthritis symptoms) and the right-hand extreme equals 100 mm, as "maximum disease activity" (maximum arthritis disease activity). The physician marked the line corresponding to their assessment of disease activity and the distance from the left edge was measured.
