- Man or woman between 18 and 70 years of age,
- Diagnosis of Crohn's disease confirmed by endoscopic and histological, or endoscopic and radiological criteria within one year or by histopathological criteria during resection,
- Clinical remission defined as Crohn´s Disease Activity Index (CDAI) \< 200, within the last two weeks. No clinical relapse due to Crohn's disease since resection,
- Moderate (i2a) or severe endoscopic recurrence (i3-i4) within 6 to 24 months after curative resection of the terminal ileum and partial colectomy with ileocolonic resection for complications of ileal Crohn´s disease and with a construction of an ileocolonic anastomosis,
- Within the neoterminal ileum at least more than 5 aphthous lesions with normal mucosa between the lesions, or skip areas of larger lesions,
- Negative pregnancy test at screening visit in females of childbearing potential,
- Use of appropriate contraceptive methods for females of childbearing potential and males with procreative capacity during treatment and at least up to 3 months after the end of treatment.
Exclusion
- Lesions confined to the ileocolonic anastomosis (i.e., \< 1 cm in length)
- Short bowel syndrome,
- Serious secondary illnesses of an acute or chronic nature, which in the opinion of the Investigator renders the patient unsuitable for inclusion into the study,

- Well-founded doubt about the patient's cooperation,
- Existing pregnancy, lactation, or intended pregnancy or impregnation within the next 15 months,
- Non-use of appropriate contraceptives in males with procreative capacity and females of childbearing potential (e.g. condoms for males, intrauterine device \[IUD\], hormonal contraception for females, or a means of contraception for a particular patient considered adequate by the responsible investigator) during treatment and within 3 months after the end of treatment,
- Participation in another clinical trial within the last 30 days, simultaneous participation in another clinical trial, or previous participation in this trial,
