Key inclusion & exclusion criteria
|
Inclusion criteria: • Diagnosis of Crohn’s disease. • Male or female, age > 18 years. • Currently treated with a combination therapy with infliximab and anti-metabolites for luminal Crohn’s disease. • Combined therapy with scheduled infliximab and anti-metabolites for at least 12 months. • Scheduled administration of infliximab 5 mg/Kg every 8 weeks over the last 6 months. • Antimetabolites administered at a stable dosage for the last 6 months: at least 1 mg/Kg or 2 mg/Kg for mercaptopurine and azathioprine, respectively, or the highest tolerated dosage if intolerance to standard dose; at least 15 mg/week subcutaneously for methotrexate. • Patients in steroid free clinical remission for at least 6 months according to retrospective assessment of the patients’ files. • CDAI < 150 at baseline. • A contraceptive during the whole study • Patients able to understand the information provided to them and to give written informed consent for the study

Primary Outcome(s)
|
Main Objective: To assess the effect of two withdrawal strategies over two years in patients with stable remission for more than6 months on combination therapy with infliximab and antimetabolites, and demonstrate that continued combination of infliximab and antimetabolites or continued monotherapy with infliximab are both superior to antimetabolites alone for maintaining sustained steroid-free clinical remission, while antimetabolites alone are non-inferior with regards to the mean time spent in remission
|
Secondary Objective: To identify baseline predictive factors of relapse in the three study groups. To assess the ability of blood CRP and fecal calprotectin to predict short term relapse in the three groups. To assess time spent inclinical remission. To assess the rate of treatment failure in the study groups. To assess the time to treatment failure in the study groups. To assess progression of bowel damage in the groups. To assess the safety and efficacy of infliximab retreatment in the antimetabolites group.To assess safety in the study groups. To assess the health related quality of life in the study groups. To assess direct and indirect costs in the study groups. To assess evolution of blood CRP and fecal calprotectin in the study groups. To assess evolution of infliximab trough levels and ATI in the Infliximab scheduled maintenance groups. To assess genetic association with the various clinical and biological outcomes.To assess the impact of 6TGN levels on the various clinical and biological outcomes

Timepoint(s) of evaluation of this end point: 2 years
|
Primary end point(s): There will be two co-primary efficacy end points Relapse rate at 2 years, relapse being defined by either one of the following events: - A CDAI>250 at any visit or between 150 and 250 with an increase of at least 70 points, over two consecutive visits one week apart associated with a CRP > 5 mg/l or a fecal calprotectin > 250 microg/g - A new opening fistula, perianal or entero-cutaneous. - An intra-abdominal abcess (size of at least 3 cm) or perianal abcess (size of at least 2 cm) - An episode of intestinal obstruction due to Crohn’s lesions confirmed by medical imaging and requiring hospitalisation (also considered as treatment failure, see below) Mean restricted time spent in remission This time will be computed in all patients, from baseline (CDAI <150 and with absence of fistula drainage) until relapse, as defined above, within the 2 first years. First and subsequent remissions will be summed up within the two first years.
|
Secondary Outcome(s)
|
Secondary end point(s): - Time to relapse in each arm. - Factors associated with time to relapse. - Time to relapse according to CRP and calprotectin value measured every 2 months over the follow up. - Sustained clinical remission defined by CDAI<150 without steroids over two years. - Treatment failure rate. Treatment failure is defined by not achieving remission after treatment adaptation following a relapse according to protocol (CDAI<150 or, in case of relapse defined by the occurence of a new fistula, the absence of fistula closure). The occurence of an intra-abdominal or peri-anal abcess and the occurence of an intestinal obstruction due to Crohn’s lesions and requiring a surgical resection or an endoscopic dilatation are also directly considered as treatment failure and will not be managed by treatment adaptation according to protocol. - Time to treatment failure. - Tissue damage progression will be assessed by the Lémann Score absolute and relative change between baseline and en of the study (2 years). - Other secondary judgement criteria: disability index, adverse events and SAE, events related to re-infusions, trough levels of infliximab, ATI , hsCRP, fecal calprotectin, direct medical costs, work productivity and activity index, short IBDQ
