A critical review of ustekinumab for the treatment of active ulcerative colitis in adults

Abstract

ABSTRACT Introduction Ustekinumab is a humanized monoclonal antibody, targeting the p40 subunit common to both human interleukin 12 and 23, approved by the European Medicines Agency and US Food and Drug Administration for the treatment of moderate-to-severe ulcerative colitis. Areas covered In this review, the results of the phase 3 UNIFI and the real-world studies assessing the efficacy and safety of ustekinumab in moderate-to-severe ulcerative colitis are discussed, as well as limitations of these studies. Predictive factors of response, the interest of therapeutic drug monitoring and the positioning of ustekinumab in specific situations are also addressed. Finally, in the light of data presented, the positioning of ustekinumab in the therapeutic algorithm of ulcerative colitis will also be considered. Expert opinion Ustekinumab has been shown to be effective to induce and maintain clinical, endoscopic and histologic remission in moderate-to-severe ulcerative colitis both in phase 3 and real-world studies, with a favorable safety profile. Overall, its favorable risk–benefit ratio, its efficacy on extra-intestinal manifestations and in biologics failure patients make ustekinumab an ideal candidate as first, second, or third-line therapy in ulcerative colitis.
