Abstract
Chimeric, humanized and fully human monoclonal antibodies directed against tumor necrosis factor-α as well as TNF receptor constructs can be administered relatively safely during long-term use for the treatment of rheumatoid arthritis (RA). Their therapeutic efficacy in patients refractory to treatment with conventional disease-modifying drugs was proven in large clinical trials and their ability to slow the progression of disease was demonstrated radiographically. The insights into the pathophysiology of RA provided by the beneficial effects of blocking proinflammatory cytokines will lead to further drug development for this destructive autoimmune disease.
