Tumour necrosis factor as a therapeutic target in rheumatoid arthritis and other chronic inflammatory diseases: the clinical experience with infliximab (REMICADE).

Therapeutic strategies that aim to neutralise the important pro-inflammatory cytokine tumour necrosis factor alpha (TNF alpha) have gained considerable prominence in the therapy of chronic inflammatory diseases, notably rheumatoid arthritis and Crohn's disease. This drug focus review will concentrate on the antitumour necrosis factor antibody infliximab (Remicade), which has been approved for the treatment of rheumatoid arthritis and Crohn's disease in both the US and Europe. In addition, infliximab is under investigation for several other indications, mainly inflammatory rheumatic diseases. Clinical trials have been persuasive that infliximab is both safe and effective, and it has been proven to be far superior to the conventional drug therapy in both rheumatoid arthritis and Crohn's disease. Remarkably, infliximab in combination with methotrexate controls both the inflammatory joint symptoms and the progression of joint damage, which renders it a very attractive therapeutic option in moderate to severe, therapy-resistant rheumatoid arthritis.
