A Randomized, Double-Blind, Phase 3b Study to Evaluate the Short- and Long-Term Efficacy and Safety of Dual Targeted Therapy With Intravenous Vedolizumab and Oral Upadacitinib Compared With Intravenous Vedolizumab and Oral Placebo for Induction Followed by Intravenous Vedolizumab Monotherapy for Maintenance in the Treatment of Adults With Moderately to Severely Active Crohn's Disease

Summary

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.
