Tumor necrosis factor-alpha antagonists twenty years later: what do Cochrane reviews tell us?

Abstract

In 1998, the U.S. Food and Drug Administration granted regulatory approval to the first tumor necrosis factor-α antagonist, infliximab, for the treatment of moderately to severely active Crohn's disease. As of 2013, there were 3 additional tumor necrosis factor-α antagonists commercially available for the treatment of inflammatory bowel disease in the United States: adalimumab, certolizumab pegol, and golimumab. Despite a vast literature describing both clinical trial and clinical practice experience with these agents, there remain important questions regarding the efficacy and safety of tumor necrosis factor-α antagonists for the treatment of inflammatory bowel disease. These questions and the best available evidence to answer them were discussed during a Cochrane Collaboration session held at the 2013 Digestive Diseases Week annual meeting. This article reviews the data from that session.
