Abstract
Tumor necrosis factor (TNF)-alpha is a central cytotoxic and proinflammatory cytokine. Research on the benefits of TNF-alpha inhibition as a form of therapy has focused almost exclusively on autoimmune, inflammatory disorders. InflixiMAB, a chimeric antibody to human TNF-alpha, was recently approved for the management of Crohn disease and rheumatoid arthritis. The potential applications of inflixiMAB in the management of cancer are just beginning to be explored. This article reviews the biology, mechanism of action, pharmacology, and toxicity of inflixiMAB. Existing clinical experience and inflixiMAB’s potential role as an immunosuppressant and antitumor agent in the management of cancer are also discussed.
