Key inclusion & exclusion criteria
|
Inclusion criteria: -Patients of both sexes aged between 18 and 75 years old, inclusively.
-Patients with diagnosis of CD, who had undergone curative ileocolonic resection, with ileocolonic anastomosis and for whom a randomization within 45 days from surgical intervention is feasible.
-If the patients had an end or loop ileostomy within 1 year prior to randomization, they can be included, but stoma closure should occur within 45 days prior to randomization.
-Patients have had faecal stream restoration at least 14 days prior to randomization.
-Patients must have at least one of the following risk factors for the development of early/severe post-operative endoscopic recurrence of their CD:
1) qualifying surgery that was their second intestinal resection within 10 years
2) third or more intestinal resections,
3) surgery for a penetrating CD complication (e.g., abscess or fistula), or
4) smoking 10 or more cigarettes per day for the past year.
-Patients treated with glucocorticosteroids (systemic or topical) must discontinue treatment within 6 weeks after surgery.
-Patients are capable of and willing to adhere to the study protocol requirements.

+post-menopausal (at least 2 years without spontaneous menses), or
+surgically sterile (bilateral tubal ligation, or hysterectomy, or ablation of both ovaries), or
+have a negative urine pregnancy test result at screening and at randomization and agree to use an acceptable method of contraception throughout their participation in the study. Acceptable methods of contraception include: condom and spermicide; intrauterine device (IUD), diaphragm with spermicide; hormonal methods (oral contraceptives, patches, implants, injectable or ring) with a documented failure rate of less than 1% per year,

Main Objective: To demonstrate the efficacy of Rifaximin –EIR 400 mg Tablet (800mg /BID, total daily dose 1600 mg) versus placebo in the prevention of endoscopic Crohn’s disease recurrence following ileocolonic resection.
|
Timepoint(s) of evaluation of this end point: 26 weeks
|
Secondary Outcome(s)
|
Secondary end point(s): ? Patients with endoscopic Rutgeerts score
