[New molecules in the treatment of inflammatory bowel disease].

Inflammatory bowel disease (IBD) is a disorder of unknown aetiology that provokes chronic inflammation of the gastrointestinal tract. Anti-tumor necrosis factor drugs have represented a major advance in the treatment of IBD patients in the last few years and also have a good safety profile. Nevertheless, these treatments are not effective in all patients and, in initial responders, there can be a loss of response in the long-term. Consequently, new treatments are needed for IBD, aimed at distinct therapeutic targets. In the last few years, new molecules have been incorporated into the therapeutic armamentarium of IBD patients. Golimumab is an anti-tumor necrosis factor monoclonal antibody with demonstrated effectiveness in the treatment of ulcerative colitis. The use of CT-P13 (biosimilar infliximab) has been approved in Europe for the same indications as the original infliximab. More recently, vedolizumab, an anti-α4β7 integrin monoclonal antibody, has been approved for the treatment of Crohn's disease and ulcerative colitis. A large number of molecules are currently under development, some of which will, in the future, broaden the therapeutic options available in the treatment of IBD patients. Finally, in the next few years, studies should aim to identify factors predictive of response to the distinct biological agents for IBD in order to allow personalized selection of the best therapeutic alternative for each patient.
