Core Tip
Core tip: In this paper we critically review recently published literature about these novel therapies, which have been the results of extensive research identifying molecular targets. Several agents have been tested and show promising data, but we focus on vedolizumab, a monoclonal antibody against the α4β7 integrin on lymphocytes, ustekinumab, a monoclonal antibody against the p40 subunit of interleukin-12 and interleukin-23, and tofacitinib, an orally administered small molecule targeting Janus-activated kinase. These three agents are most likely to find their way soon to the market and offer significant therapeutic advantages for the management of Crohn’s disease and ulcerative colitis.
