Study to Evaluate the Safety, Tolerability and Efficacy of Tocilizumab in Participants With Rheumatoid Arthritis (RA) Who Have an Inadequate Response to Non-Biologic Disease Modifying Anti-rheumatic Drugs (DMARDs) and/or Anti-tumor Necrosis Factor (Anti-TNF) Therapy

A Study to Observe the Safety, Tolerability and Efficacy of Tocilizumab in Patients With Moderate to Severe Active Rheumatoid Arthritis Who Have an Inadequate Response to Current Non-biologic DMARD and/or Anti TNF Therapy.

This observational study will evaluate the safety, tolerability and efficacy of tocilizumab in participants with moderate to severe RA who have an inadequate response to current non-biologic DMARD and/or anti-TNF therapy. Data will be collected from each participant during tocilizumab therapy and on follow-up for a total of 12 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Adverse Events (AEs) or Serious AEs (SAEs)	An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal product. An AE is considered as an SAE if it fulfills one of the following criteria: a) fatal or life-threatening, b) requires in-patient hospitalization or prolongation of existing hospitalization, c) results in a persistent or significant disability, d) results in a congenital abnormality/birth defect, e) is medically significant. AEs included serious as well as non-serious AEs.	Up to 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Achieving a Clinically Meaningful Improvement in Disease Activity Score 28 (DAS28) (Reduction of At Least 1.2 Units) at Every Visit	DAS28 was calculated from the tender joint count (TJC) of 28 joints, swollen joint count (SJC) of 28 joints, erythrocyte sedimentation rate (ESR) (in millimeters [mm]/hour), and the participant's global assessment of disease activity (100 mm visual analog scale [VAS]: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*square root (√) of TJC + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity. A reduction of at least 1.2 units of DAS28 score from previous visit is considered as clinically meaningful improvement.	Visit 3 (Week 4), Visit 4 (Week 8), Visit 5 (Week 12), Visit 6 (Week 16), Visit 7 (Week 20), Visit 8 (Week 24), Visit 9 (Week 28), Visit 10 (Week 32), Visit 11 (Week 36), Visit 12 (Week 40), Visit 13 (Week 44)
Time Required to Achieve Clinically Meaningful Improvement in DAS28 (Reduction of At Least 1.2 Units)	DAS28 was calculated from the TJC of 28 joints, SJC of 28 joints, ESR (in mm/hour), and the participant's global assessment of disease activity (100 mm VAS: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*√(TJC) + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity. A reduction of at least 1.2 units of DAS28 score from previous visit is considered as clinically meaningful improvement. Time taken to achieve clinically meaningful improvement in DAS28 was reported.	Up to 12 months
Percentage of Participants Achieving Low Disease Activity (DAS28 Less Than [<] 3.2 Units) at Every Visit	DAS28 was calculated from the TJC of 28 joints, SJC of 28 joints, ESR (in mm/hour), and the participant's global assessment of disease activity (100 mm VAS: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*√(TJC) + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity. Low Disease Activity is defined as DAS28 value of <3.2 Units at the time of assessment.	Visit 3 (Week 4), Visit 4 (Week 8), Visit 5 (Week 12), Visit 6 (Week 16), Visit 7 (Week 20), Visit 8 (Week 24), Visit 9 (Week 28), Visit 10 (Week 32), Visit 11 (Week 36), Visit 12 (Week 40), Visit 13 (Week 44)
Time Required to Achieve Low Disease Activity (DAS28 <3.2 Units)	DAS28 was calculated from the TJC of 28 joints, SJC of 28 joints, ESR (in mm/hour), and the participant's global assessment of disease activity (100 mm VAS: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*√(TJC) + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity. Low disease activity is defined as decrease in DAS28 to a value <3.2 Units at the time of assessment. Time taken to achieve low disease activity was reported.	Up to 12 months
Percentage of Participants Achieving Remission (DAS28 <2.6 Units) at Every Visit	DAS28 was calculated from the TJC of 28 joints, SJC of 28 joints, ESR (in mm/hour), and the participant's global assessment of disease activity (100 mm VAS: 0 mm=no disease activity to 100 mm=maximum disease activity). The formula for calculating DAS28 score using ESR value is: 0.56*√(TJC) + 0.28*√(SJC) + 0.70*log natural (ESR) + 0.014*global assessment of disease activity (100 mm VAS). Remission is defined as DAS28 value of <2.6 units at the time of assessment.
