Clinical Trial Summary

Despite the advent of multiple novel medications, many patients with Crohn's disease (CD) fail to achieve mucosal healing (MH). Exclusive enteral nutrition (EEN) has been shown to induce clinical remission accompanied by MH in many of CD patients. The aim of this proposal is to explore the effectiveness of the "Tasty&Healthy" dietary approach based on avoiding "pro-inflammatory" and processed ingredients, for inducing and maintaining remission and MH in children and young adults. This approach is based on the previously published charity cook-book "Tasty&Healthy" and might be more feasible than currently available nutritional treatments in CD. It does not offer a rigid diet with specific nutrients and does not require concurrent use of a formula feed. The investigators hypothesize that a flexible dietary intervention of excluding processed and pro-inflammatory ingredients will improve the rate of clinical remission and MH without the need for liquid formula or structured rigid diet which are more difficult to adhere to. The investigators also hypothesize that home kits of Fecal calprotectin (FC), can personalize the diet thereby increasing feasibility for maintenance therapy in some patients.

Clinical Trial Description

The investigators plan to conduct a set of three studies: Two randomized controlled trials (RCT) both including the Tasty&Healthy dietary intervention for 8 weeks in CD patients aged 6-24 years vs. 1) EEN in mild-moderate CD, and the other RCT in CD patients aged 6-40 years vs. 2) a control group continuing their habitual diet in those with mucosal inflammation despite stable medical treatment, but who are in clinical remission or have only minimal symptoms not requiring immediate treatment. As a third study, responders from both trials will be offered to participate in an open label extension personalized-diet study of further 16 weeks (total 24 weeks), in which gluten and dairy will be gradually re-introduced based on repeated monthly home assays of FC while otherwise following the Tasty&Healthy dietary intervention in a treat-to-target management approach. Patients will be evaluated at baseline, week 4 and week 8 with additional weekly phone visits to ensure adherence with the diets and address questions. The extension study will include two clinic visits at weeks 16 and 24 and a monthly call to ensure adherence. The investigators hope to establish a dietary-approach which is simpler to implement than current nutritional alternatives. It will enable high flexibility in the allowed foods and does not require liquid formula. In turn, this could position Tasty&Healthy, not merely for inducing remission, but also as a feasible maintenance strategy in selected patients. ;
