A Study of Vedolizumab in Adults With Crohn's Disease (CD)

Complete Remission in Patients With Moderately to Severely Active Crohn's Disease Treated With Vedolizumab - A Multicenter, Prospective Observational Cohort Study in Canada, Italy, and Israel

The main aim of this study is to see if adults with CD treated with vedolizumab have less symptoms and inflammation of the bowel assessed by ultrasonography.

Participants will be treated with vedolizumab according to their clinic's standard practice.

This is a non-interventional, prospective study of participants with moderately to severely active CD who are initiating treatment with vedolizumab according to the current summary of product characteristics (SmPC) in the real world setting.

The study will enroll approximately 100 participants. The data will be collected prospectively at the study sites and will be recorded into electronic case report forms (e-CRFs). All the participants will be assigned to a single observational cohort:
