- Patient taking corticosteroids orally, concomitant immunosuppressive agents,
mesalamine, and antibiotics are allowed at stable dose for at least three months
before inclusion. Steroid tapering has to be set up at Week 10 after starting
Vedolizumab, according to the European Crohn and Colitis Organisation (ECCO)
recommendations with a progressive decrease of steroids of 5 mg/day every week until
complete withdrawn.

- Informed written consent given.

Exclusion Criteria:

- Existing pregnancy, lactation, or intended pregnancy within the next 15 months

with their participation in the study

investigator renders the patient unsuitable for inclusion into the study

with no evidence for recurrence for 5 years)

- Short bowel syndrome

- Previous treatments with natalizumab, efalizumab or rituximab.

- Previous treatment with adalimumab within 30 days prior enrollment or infliximab and
certolizumab pegol within 60 days before enrollment. This deadline can be shortened by
judgment of investigator.

- Prior extensive colonic resection, obstructive (symptomatic) intestinal stricture,
abdominal abscess, active or latent tuberculosis,

- Documented Clostridium difficile superinfection;

- Indeterminate colitis
