A Randomized, Double-blind, Parallel Group Study of the Safety and Effect on Clinical Outcome of Tocilizumab SC Versus Tocilizumab IV, in Combination With Traditional Disease Modifying Anti-rheumatic Drugs (DMARDs), in Patients With Moderate to Severe Active Rheumatoid Arthritis
In Brief
A Phase 3 clinical trial evaluating tocilizumab SC, tocilizumab IV, and 3 other interventions for Rheumatoid Arthritis. Completed, enrolled 1,262 participants across 216 sites in 26 countries.
Detailed Summary
This randomized, double-blind, parallel group study compares the efficacy and safety of subcutaneous (sc) versus intravenous (iv) administration of tocilizumab in participants with moderate to severe active rheumatoid arthritis. Participants were randomized to receive either tocilizumab 162 mg sc weekly plus iv placebo every 4 weeks, or tocilizumab 8 mg/kg iv every 4 weeks plus sc placebo weekly during the double-blind period from baseline to Week 24. The double-blind period was followed by a 72-week open-label treatment with some switching of sc and iv administration. No placebo was administered in the open-label phase. Participants continued on their stable dose of disease-modifying antirheumatic drugs (DMARDs) throughout the study. Anticipated time on study treatment was 2 years.
