E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to complare the effectiveness of weekly subcutaneouslly administered MTX fro mainteining relapse- free sustained steroid/EN - free 1 year remission compared with: - daily oral AZA/EMP in low ris paediatric CD - subcutaeously administered adalimumab in high risk paediatric CD |
|
E.2.2 | Secondary objectives of the trial |
compparison between the two treatment arms per risk group (high ris or low risk for aggresive disease evolution) (and inter-risk paediatric CD) |
|
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 |
Paediatric Inflammatory Bowel Diseases Network for Safety, Efficacy, Treatment and Quslity Improvement of care (PIIBD-setQuality) |
Development and validation of a treatment algorithm for children diagnosed with an inflammatory bowel disease based on factors that could predict the risk (high or low) of complicated or relapsing disease, also by decreasing the risks and complications throughout the life due to an uncontrolled progression of the disease (algorithm of personalized treatment and stratified risk) |
|
E.3 | Principal inclusion criteria |
• Children 6-17, with a new-onset CD diagnosed < 6 months using established criteria (28, 29), requiring a steroid-based or EN based induction therapy • At initial diagnosis, wPCDAI >40 or CRP>2 times upper limit at diagnosis • all wPCDAI scores (0-120) are possible at inclusion (patients in remission and patients with active disease) • Luminal active CD (B1) with or without B2 and/or B3 disease behavior • Initial exposure to 5-ASA and derivate is tolerated • Exposure to antibiotics is tolerated • If one of the following criteria is present, patients are allocated to the high risk group prior randomization: • Complex fistulizing perianal disease • Panenteric disease phenotype (defined as L3 with L4b per Paris classification or L3 with deep ulcers in duodenum, stomach or oesophagus (not HP- or NSAID-related)) • Severe growth impairment (height z-score <-2 or crossing 2 percentiles or more) likely related to CD • Significant hypoalbuminemia (<30g/l), elevated C reactive protein (CRP) (at least 2 times above normal range), or wPCDAI >12.5 despite 3 weeks of optimized induction therapy with steroids or EEN • B2, B3 or B2B3 disease behavior • Overall cumulative disease extend of ≥60 cm • Informed and signed consent |
|
E.4 | Principal exclusion criteria |
• Patients with wPCDAI<42,5 at initial diagnosis, except if CRP>2 times upper limit • No induction therapy with steroids or enteral nutrition • Previous therapy with any IBD-related medications other than induction therapy as detailed in this protocol (except 5-ASA). • Pregnancy or refusal to use contraceptives during the study period in pubertal patients (both boys and girls) unless absolute abstinence (no sexual activity) is confirmed at each study visit. Positive pregnancy testing throughout the study will trigger prompt withdrawal of the patient from the study. • Lactating mothers • Children with perianal fistulising disease who require surgical therapy (drainage, seton placement) • Patients homozygous for TPMT or those with TPMT activity <6 nmol/h/ml erythrocytes or <9nmol 6MTG/g Hb/h), unless they qualify as high risk patients • Evidence of un-drained and un-controlled abscess/phlegmon • Contraindication to any drugs used in the trial (including intolerance/hypersensitivity or allergy to either study drug (thiopurines, methotrexate or adalimumab)) • Current or previous malignancy • Serious comorbidities (such as renal insufficiency, hepatitis, respiratory insufficiency) interfering with drug therapy or interpretation of outcome parameters or will make it unlikely that the patients will finish the trial. • Infection with mycobacterium tuberculosis, hepatitis B or C, HIV • Moderate to severe heart failure (NYHA class III/IV) • Oral anticoagulant therapy, anti-malaria therapy • Live vaccines exposure (including yellow fever) less than 3 weeks prior inclusion
