Title: Randomized Placebo-controlled Study of Two Treatment Strategies Based on Tocilizumab (TCZ) With or Without Methotrexate (MTX) and Possible Addition of Other Disease-modifying Anti-rheumatic Drugs (DMARDs) in Patients...
Brief Summary: This 2 arm study will compare 2 treatment strategies based on tocilizumab in combination with methotrexate or placebo in patients with moderate to severe rheumatoid arthritis. Patients receiving methotrexate treatment will be randomized to receive either a) tocilizumab 8 mg intravenous (iv) every 4 weeks + methotrexate orally (po) weekly or b) tocilizumab 8 mg iv every 4 weeks + placebo po weekly. After the first 24 weeks of blinded treatment, treatment adjustments (increase or decrease of treatment intensity) may be introduced at intervals, based on response. The anticipated time on study treatment is up to 3 years, and the target sample size is approximately 470 patients.
