Tocilizumab - a new step in rheumatoid arthritis treatment.
Rheumatoid Arthritis is a chronic systemic inflammatory disease characterized by joint pain, stiffness and swelling, with progressive destruction of small joints of the hands and feet. Methotrexate remains the most commonly used therapy and has been the recommended standard against which new drugs should be evaluated and, to date, there is limited evidence that monotherapy with other treatments is superior to MTX. The introduction of biologic agents, such as TNFα-antagonists, represented an advance in the treatment of RA. However, there are still patients with no or inadequate response, patients in whom responsiveness to treatment is lost over time, and patients in whom safety issues may develop. Thus, patients may benefit from treatment with newer biologic agents with a different mechanism of action. Tocilizumab is an IL-6 receptor inhibitor which shows significant (and rapid) clinical efficacy in the treatment of Rheumatoid Arthritis patients, as assessed by ACR responses and DAS remission rates, with an acceptable safety profile.
