The role of tocilizumab in the management of rheumatoid arthritis.

INTRODUCTION: The introduction of biological treatments has improved the outlook for patients diagnosed with rheumatoid arthritis. There are now a range of different agents, targeting various pathways involved in the inflammatory process. Tocilizumab , a fully humanised anti-interleukin-6 receptor monoclonal antibody is licensed for the treatment of rheumatoid arthritis and systemic juvenile idiopathic arthritis. AREAS COVERED: This article reviews and appraises the available evidence regarding the efficacy and safety of tocilizumab in rheumatoid arthritis, as identified in PubMed and Embase searches. EXPERT OPINION: Clinical trial data suggest that tocilizumab has similar efficacy both clinically and in reducing structural progression to that seen with the TNF inhibitors. Patients who might be particularly suitable for tocilizumab are those who have failed multiple TNF inhibitors, those with a high inflammatory response as part of their disease and those unable to tolerate methotrexate, given the good responses seen with monotherapy.
