Title: A Randomized, Double-blind, Parallel Group Study of Safety and the Effect on Clinical Outcome of Tocilizumab Subcutaneous (sc) Versus Placebo sc in Combination With Traditional Disease Modifying Anti-rheumatic Drugs (DMARDs) in Patients With Moderate to Severe Active Rheumatoid Arthritis
Brief Summary: This randomized, parallel-group, placebo-controlled, multicenter study will evaluate the reduction in disease activity and the safety of tocilizumab (RoActemra/Actemra) in combination with traditional disease-modifying anti-rheumatic drugs (DMARDs) in patients with active, moderate to severe rheumatoid arthritis. In the double-blind part of the study, patients will be randomized to receive either 162 mg tocilizumab or placebo subcutaneously every 2 weeks for 24 weeks using a pre-filled syringe. In the open-label part of the study, patients will be randomized to receive 162 mg tocilizumab subcutaneously every 2 weeks from Week 24 to Week 96 using a pre-filled syringe or an auto-injector.
