E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the proportion of CD patients without endoscopic postoperative recurrence (i0-i1) at 12 months (M12) in the arm receiving therapy escalation compared to status quo arm in patients having an i2 endoscopic postoperative recurrence 6-12 months after ileocolonic anastomosis. |
|
E.2.2 | Secondary objectives of the trial |
- To compare the proportions of patients with severe endoscopic recurrence (i3-i4) between both arms and the proportion of i2b-i3-i4 patients at 12 months (M12) between both arms - To compare the proportions of patients with clinical postoperative recurrence, surgical recurrence, need for endoscopic dilatation at 12 months (M12) between both arms. - To compare the mean change in Two Item Patient Reported Outcome (PRO2) from baseline to 12 months (M12) between both arms. - Evaluate the safety of therapy during the 12 months study period. - Evaluate the quality of life and work productivity impact during the 12 months study period. - To compare the clinical, endoscopic and surgical outcomes of 3 pre-specified subgroups: according to i2 subtype (i2a versus i2b patients), smoking status and immunosuppressant status.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
1.Endoscopic ancillary study A post-hoc analysis of the centrally read videos will be performed. All videos recorded for the trial will be analysed. A specific endoscopic scoring sheet will be developed including detailed information on the localization of the lesions (blind loop, entry of the terminal ileum, anastomosis, precise distance from the anastomosis).
2.Long-term follow-up ancillary study The primary objective of this study is to evaluate the benefit of CT-P13 treatment at 5 years in terms of preventing surgical postoperative recurrence compared to the status quo arm. The secondary objectives are to assess the benefit of CT-P13 treatment in terms of preventing clinical recurrence, surgical recurrence and need for endoscopic dilatation at 2, 3, 4 and 5 years and to evaluate the CT-P13 drug persistence.
3. Ancillary studies based on biological collection A multi-omics analysis will be performed at KU Leuven using samples collected for biological collection, including blood and mucosal transcriptomics, genetic susceptibility analysis and metagenomics.
4. Health economics Crohn’s disease related direct healthcare costs will be compared between the two treatment arms |

E.3 | Principal inclusion criteria |
- Age > 18 years - Diagnosis of Crohn's disease according to usual criteria - Intestinal resection with ileocolonic anastomosis removing all Crohn’s disease inflammatory lesions performed within the last 6-12 months (patients who underwent a two stage surgical procedure are also eligible if the endoscopic evaluation is performed 6-12 months after restoration of the fecal stream) - Postoperative endoscopy performed between 6 and 12 months +/- 2 months after ileocolonic anastomosis reaching the neoterminal ileum - Postoperative endoscopic recurrence classified i2 according to the Rutgeerts score at 6-12 months, validated by a blinded central reading - The patient is willing to start infliximab CT-P13 at a fixed schedule of 2 intravenous infusions at week 0 and week 2 followed by subcutaneous CT-P13 every other week from week 6 onwards
|
|
E.4 | Principal exclusion criteria |
- Patients with an ostomy - Patients with ulcerative colitis or IBD type unclassified - Patients with an ileorectal or ileal pouch-anal anastomosis - Patients exposed to infliximab before index surgery with a primary non-response (no clinical effect after 2 infusions or at the discretion of the treating gastroenterologist) or history of infusion reactions to infliximab or history of detectable anti-infliximab antibodies - Patients with symptoms of active CD, defined as average daily SF ≥ 3.5 and average daily AP score ≥ 1.5, having started after a free interval without symptoms of one month after surgery - Patients with obstructive symptoms of CD defined by a CDOS > 4 (15) (see Appendix for description of the score). Asymptomatic patients receiving an endoscopic dilatation for a non-passable stenosis at baseline endoscopy in centres where it is a current practice to estimate the lesions extent can be included. - Patients treated with any biological therapy (except for intraocular injections) or an investigational medical product after index surgery - Patients having started thiopurines or methotrexate more than 6 weeks after ileocolonic anastomosis with restoration of the faecal stream - Patients in whom not all inflammatory lesions have been removed at index surgery: e.g. incomplete ileo-colonic resections, active colitis. - Patients with active perianal Crohn's disease - Patients with a contraindication to infliximab: cancer in the 5 years prior to inclusion, excluding non-melanoma skin cancer, active tuberculosis or untreated latent tuberculosis, moderate or severe heart failure, HIV or HBV infection (serology < 3 months), recent live vaccination (within 4 weeks of baseline). - Pregnant women - Patients under legal protection or unable to express their consent. - Patients not affiliated to a health insurance system. - Patients deprived of liberty by judiciary or administrative decision or hospitalized without consent or admitted in a sanitary or social institution for another reason than research.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint will be the proportion of patients with a treatment success defined as an i0-i1 modified Rutgeerts score (mRS) at 12 months (M12) Treatment failure will be defined as: - Modified Rutgeerts score > i1 at 12 months (M12) - OR Clinical postoperative recurrence: Average daily stool frequency ≥ 3.5 and average daily abdominal pain score ≥ 1.5, AND * increased CRP compared to inclusion, at least + 10 mg/l * OR increased fecal calprotectin compared to inclusion, at least + 250 µg/g - OR Endoscopic dilatation defined as a need for a balloon insufflation at the ileocolonic anastomosis during an ileocolonoscopy when a non-passable stenosis was present in a patient having obstructive symptoms (Crohn Disease Obstructive Scale - CDOS > 4) before endoscopy. Endoscopic dilatation performed in asymptomatic patients in centres where it is a current practice to estimate the lesions extent will not be considered for this criterion. - OR Surgical recurrence within 12 months study period defined as a need for a new ileocolonic resection. - OR Active perianal Crohn's disease or other Crohn's disease location (e.g. colitis, jejunitis) leading to a treatment modification (initiation of a new Crohn's disease therapy including steroids or CT-P13 optimization) before 12 months ileocolonoscopy. - OR Definitive treatment discontinuation
