Registration Number
NCT02620007
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

The primary objective of this trial is to assess whether a 12-week treatment with Ciprofloxacin and Rifaximin is superior to placebo to obtain endoscopic remission in adherent-invasive E. coli (AIEC)-colonized patients with ileal Crohn disease (CD), with or without involvement of the caecum or the right colon.
