A Non-Interventional Study in Rheumatoid Arthritis Patients Treated With Tocilizumab (RoActemra/Actemra)
- Conditions
- Rheumatoid Arthritis
- Interventions
- Other: No intervention
- Registration Number
- NCT01613378
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This multi-center, non-interventional study will evaluate the pattern of usage in clinical practice, efficacy and safety of tocilizumab in patients with rheumatoid arthritis. Patients initiated on treatment with tocilizumab according to the licensed Canadian product monograph recommendations will be followed for 12 months from the start of treatment.

Group Intervention Description Rheumatoid Arthritis Cohort No intervention The cohort included participants with moderate to severe rheumatoid arthritis (RA) in whom the treating physician made the decision to initiate tocilizumab treatment.
- Primary Outcome Measures
Name Time Method Percentage of Participants on Tocilizumab Treatment at 6 Months After Treatment Initiation At 6 months
- Secondary Outcome Measures
Name Time Method Change From Baseline in C-Reactive Protein (CRP) From baseline to Month 12 The serum concentration of C-reactive protein (CRP) was measured. A reduction in the level of CRP was considered an improvement.
Change From Baseline in Tender Joint Count (TJC) From baseline to Month 12 Following an assessment of 68 joints for tenderness, joints were classified as tender or not tender by the investigator.
Change From Baseline in Disease Activity Score 28 (DAS28) From baseline to Month 12 The DAS28 scale is a combined index for measuring disease activity in rheumatoid arthritis. Scores range from 0 to 10, with higher scores representing more disease activity.
Number of Participants With Changes in Severity of Extra-Articular Manifestations at 12 Months At 12 months The severity of extra-articular RA manifestations ascertained were the nodules, Raynaud's phenomenon, secondary Sjogren's syndrome, pulmonary fibrosis, pericarditis, polyneuropathy, scleritis, severe cutaneous vasculitis, weight loss and anemia. Percentages are based on the total number of participants who responded "YES" to changes in extra- articular RA manifestations (new presence or change in severity) since the last visit. NA=Not applicable
Change From Baseline in Swollen Joint Count (SJC) From baseline to Month 12 Following an assessment of 66 joints for swelling, joints were classified as swollen or not swollen by the investigator.
Change From Baseline in Erythrocyte Sedimentation Rate (ESR) From baseline to Month 12 The erythrocyte sedimentation rate (ESR) was analyzed at the site using the kit provided by the central laboratory. A reduction in the level of ESR was considered an improvement.
Change From Baseline in Patient Global Assessment of Disease Activity (Visual Analog Scale, VAS) From baseline to Month 12 With VAS, participants specify their level of agreement to a statement by indicating a position along a continuous line between two endpoints, with 0 being the lowest level and 100 being the highest level of disease activity.
Change From Baseline in Physician Global Assessment of Disease Activity (Visual Analog Scale, VAS) From baseline to Month 12 With VAS, physicians specify their level of agreement to a statement by indicating a position along a continuous line between two endpoints, with 0 being the lowest level and 100 being the highest level of disease activity.
Change From Baseline in Patient Assessment of Fatigue (Visual Analog Scale, VAS) From baseline to Month 12 With VAS, participants specify their level of agreement to a statement by indicating a position along a continuous line between two endpoints, with 0 being the lowest level and 100 being the highest level of fatigue.
Percentage of Participants With Changes in Extra-Articular Manifestations at 12 Months At 12 months The extra-articular RA manifestations ascertained were the nodules, Raynaud's phenomenon, secondary Sjogren's syndrome, pulmonary fibrosis, pericarditis, polyneuropathy, scleritis, severe cutaneous vasculitis, weight loss and anemia. Percentages are based on the total number of participants with available data.
Change From Baseline in Duration of Morning Stiffness (Visual Analog Scale, VAS) From baseline to Month 12 With VAS, participants specify their level of agreement to a statement by indicating a position along a continuous line between two endpoints, with 0 being the lowest level and 100 being the highest level of morning stiffness.
Change From Baseline in Patient Assessment of Pain (Visual Analog Scale, VAS) From baseline to Month 12 With VAS, participants specify their level of agreement to a statement by indicating a position along a continuous line between two endpoints, with 0 being the lowest level and 100 being the highest level of pain.
