A Study of Vedolizumab With and Without Upadacitinib in Adults With Crohn's Disease

연구 개요

The main aim of this study is to learn whether vedolizumab and upadacitinib given together (also called dual targeted therapy or DTT) reduces bowel inflammation and ulcers in the bowel compared to vedolizumab only (also called monotherapy) in adults with moderately or severely active Crohn's Disease (CD) after 12 weeks of treatment. Other aims are to learn how safe and effective DTT is compared to monotherapy for these participants. All participants will receive DTT (either vedolizumab and upadacitinib or vedolizumab and placebo) for 12 weeks. Participants responding to the treatment will then receive vedolizumab only (monotherapy) for an additional 40 weeks. During the study, participants will visit their study clinic 15 times.
