Study type | Observational |
Descriptive : A 12-months multicenter, observational, prospective cohort study. Population : IBD patients under stable clinical and biological remission will be proposed to switch from the IV vedolizumab to the SC vedolizumab as part of routine care. All consecutive IBD patients in IBD centers participating in the study will be proposed to participate in the study during their regular outpatients' visits. Objectives : The primary objective of DOPER study is to describe SC vedolizumab persistence after switching from IV vedolizumab to SC vedolizumab at month 12.
