Randomized Trial for Unstable Pediatric Crohn's Disease Patients Comparing the Use of Crohn's Disease Exclusion Diet (CDED) on Top of Standard Therapy Versus Standard Therapy Alone.
This research is a multicenter French randomized and single blinded phase III clinical trial evaluating two treatment strategies among Crohn's disease (CD) patients. The main objective is to assess if the addition of Crohn's Disease Exclusion Diet (CDED) to ongoing standard medication is superior to reduce the rate of relapses over 12 months compared to standard medication alone in children/adolescents with unstable CD responding with remission after a 2-months course of CDED
• Child/Adolescent aged 6-17 years with a confirmed diagnosis of CD (for at least 3 months) with an active disease (defined as: wPCDAI \>12.5 or CRP \> 2 times upper limit or calprotectin levels \>250µg/g if available) despite anti-inflammatory (5-ASA and derivates), corticosteroids, immunomodulator (thiopurines or methotrexate) and/or biologic therapy (anti-TNF, anti-integrin anti-IL23 antibodies)
• For girls of childbearing age: a negative pregnancy test, and use of an effective method of contraception (abstinence, oral contraceptives, intra-uterine device, diaphragm with spermicide and condom)
• Patient willing to comply with daily intake of an exclusion diet
• Informed and signed consent of parents
• Patient affiliated to social security (or health insurance)
