| E.1.3 | Condition being studied is a rare disease  |  No  | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| Aim of the prospective randomized placebo controlled study is to prove the efficacy of biological therapy (Infliximab) in prevention of Crohn's disease recurrence in 24 months (defined as endoscopic recurrence - in endoscopic score of i2 or more) after surgery in ileocecal region | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
| Secondary aim is to compare the rate of clinical relapse in both groups (defined as a increase in CDAI score of 75 points). To design algorithm of disease recurrence monitoring in terms of multi specialty cooperation (surgeon, gastroenterologist, radiologist, immunologist) using new non-invasive techniques (biological markers, biochemistry markers, NMR- enterography, ultrasound) including calculation of costs. | 
 
 
 | 
| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
- Suitable patients for the study are all patients admitted for surgery due to ileocecal  Crohn's disease, who have never been treated by any biological therapy (naive) - age 18-65years - no signs of system infection (viral hepatitis) - negative chest X-ray and Quantiferron test for TBC - no signs of heart failure 
 | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
- psychical inability to uderstand the instructions and signing of the informed consent  - pregnant or lactating females, or females who intend to get pregnant within 1 year - patients with known allergy to Infliximab - residual bowel disease (except perianal form) or after multiple resections, strictureplasty or with ostomy  - used biological therapy before - signs of viral hepatitis 
 Further exclusion criteria - adverse events after study medication - patients with postoperative complications prolonging hospitalization for more than 2 weeks - different perioperative finding - residual bowel disease (except perianal form) - different surgical procedure (stricturoplasty, ostomy) - protocol failure - patient refuses further participation in the study - findings of malignancy 
 The criteria of premature termination of prophylaxis - signs of recurrence of Crohn's disease (increase CDAI of 75pts, endoscopic score >2, need of reoperation) |
