Description of intervention(s) / exposure
Randomized Ileal Crohn’s disease study of exclusive Enteral Nutrition (RICE) is a randomised controlled study for the treatment of ileal Crohn’s disease (CD) randomising EEN versus standard therapy in a single-blinded trial design. In Phase 1 of the study consenting patients with either severe Crohn's disease or symptomatic terminal ileal strictures/ perforation requiring surgical resection are randomised to receive EEN using polymeric formula versus calorie-matched standard of care diet for 6 weeks (in the subgroup of patients requiring surgery this will be taken in the 6 weeks immediately pre-surgery). In phase 2, patients that required surgery will undergo post-operative re-randomization to determine the effects of 6 months of partial enteral nutrition (PEN) on the prevention of post-operative CD. Other post-operative patients who will have resection of the terminal ileum may be recruited directly into phase 2 of the study without having participated in phase 1.
In phase 1 of the study, participants will consume EEN in the form of Nestle Modulen, prescribed by a dietician to meet all their nutritional requirements. The aim is to achieve compliance for >80% of consumed calories in the form of Nestle Modulen, which will be monitored through use of food diaries and regular follow up. In Phase 2 of the study Nestle Modulen will be consumed for about 50-60% of normal daily calorie intake and again adherence will be monitored through the use of a food diary.

Outcomes
Primary outcome [1] 297073 0
Primary end point for phase 1 of the study is both clinical remission (defined as CDAI less than or equal to 150) and MRI remission (defined as increase in the terminal ileum cross-sectional lumen area by at least 100% as assessed on MRE by a central blinded GI radiologist), following 6 weeks of EEN versus standard of care calorie-matched diet for Crohn’s disease patients presenting with a severe disease flare or prior to planned surgical resection of the terminal ileum. Patients need to be both in clinical remission and MR remission in order to score the primary outcome.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Computer based randomisation will be performed. Block randomisation will be performed centrally via an online random sequence generator. Each randomization code will be sealed in an opaque envelope, and these will be sent to the various study sites. Once a study participant signs an informed consent sheet and is deemed to meet all the inclusion criteria and none of the exclusion criteria, the study site investigator is to open the envelope and phone the principal investigator or research coordinator with the code contained in the envelope, in order to reveal to what group that particular participant has been randomised to. The envelop is only to be opened when informed consent sheet is signed. Record will be kept of every person requesting a code. The above method would allow for allocation concealment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
As detailed above an online random sequence generator will be used.

Efficacy
Statistical methods / analysis
The study is designed and statistically powered with the pre-specified intention of demonstrating a clinically meaningful difference between the treatment and control arm (as opposed to a statistically significant but clinically inconsequential difference).
The study is to be powered such that there is a >80% probability of demonstrating a difference with a p value of 0.05 using a two tailed t-test.
Based on radiological remission rates from an open-labelled study of 54%, the predicted study rates based on available data and anecdotal experience are as follows: remission rate 60%, control response 40%, drop-out rate 20%.
Sample size analysis: assuming a two-sided alpha of 0.05, a treatment remission rate of 60%, control remission rate of 40% and a drop out rate of up to 20% in each arm, randomising 2 : 1 ratio with non-inferiority margin of -0.1, 30 patients in control group and 60 in the active treatment group (i.e. 90 patients in total) has a power of > 80% in an intention-to-treat analysis.

Summary
Brief summary
Crohn's disease (CD) is a chronic inflammatory condition of the bowel that carries a 70% lifetime risk of requiring surgical resection due to stricture formation or bowel perforation. CD often requires prolonged courses of immunosuppressive medications in order to induce remission, and these medications in themselves carry their own sets of risks. Exclusive Enteral Nutrition (EEN) has proven successful in inducing remission in pediatric CD patients. EEN is a polymeric supplement feed that is meant to provide all of the daily requirements of macro and micro nutrients. It is intended that patients consume this polymeric supplement feed for at least 80% of their daily nutritional requirement. Uncontrolled studies and small controlled trials suggest that there are benefits of EEN in adult CD patients as well but to date there has been no large controlled trial to formally test this hypothesis.

The proposed study will seek to test in a randomized controlled trial the hypothesis that EEN can improve outcomes in patients with severe CD affecting the terminal ileum, which is a part of the bowel that is most commonly affected by CD. The study will have two phases. Phase 1, will see participants randomized into two groups, either EEN or standard of care calorie matched diet for 6 weeks prior to their planned operation. The primary outcome compared between the two groups at the end of phase 1 is both clinical disease remission and reduction of bowel wall swelling of the terminal ileum as measured by Magnetic Resonance (MR) enterography, an imaging modality commonly used in CD. Other secondary outcomes which will be assessed at the end of Phase 1 include quality of life, nutritional status, microbiome comparison, mean intestinal permeability, tolerability of diet, health economics and predicative markers for response.

Following their surgical resection, participants will be re-randomized for phase 2 of the trial. Phase 2 of the trial will seek to test the hypothesis that partial enteral nutrition for 6 months as compared to standard of care calorie matched diet results in improved outcomes following surgical resection of the terminal ileum. The primary outcome at the end of phase 2 will be assessment of recurrence via colonoscopy after 6 months of the prescribed diet. Other secondary outcomes which will be assessed at the end of Phase 2 include quality of life, nutritional status, microbiome comparison, tolerability of diet and health economics.
