Management of IBD depends on stage and location of the inflammation consist of the classic conventional treatment and the more new treatment with biologics agent. Biologics agent refers to monoclonal antibodies with activity directed against specific targets involved in the pathogenesis of chronic inflammatory conditions. Advances in the understanding of the specific mechanisms of pathogenesis IBD led to the development of targeted treatment. Today there are six biologics agent approved and used as therapy and there still many other biologics agent on research progress. Many reports show positive report about efficacy for the biological therapy compared with placebo and conventional treatment for the IBD.
