Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
8 week treatment with exclusive enteral nutrition (liquid diet) instead of corticosteroid therapy. The liquid diet consists of commercially available a polymeric nutrition formula. It will meet all of the participants calorie and nutrient requirements, no food or fluid other than water is allowed. It is to be taken orally, or via nasogastric tube if not tolerated orally, 6 - 8 times per day based on individual requirements.
Intervention code [1] 286483 0
Treatment: Other
Comparator / control treatment
8 week treatment with corticosteroid therapy as prescribed by the participant's gastroenterologist. The corticosteroid medication will be taken orally as per standard practice.
Control group
Active

Outcomes
Primary outcome [1] 288822 0
Demonstrate patterns and extent of changes in faecal inflammatory markers consequent to exclusive enteral nutrition. Upon receipt stool samples will be stored at -80 degrees. Batched stool samples will be subsequently retrieved from storage and used to measure calprotectin, S100A12 and osteroprotegrin by immunoassay using standard methods.
Timepoint [1] 288822 0
Assess at start of intervention, every 2 weeks during 8 week intervention and then after 3 and 6 months
Secondary outcome [1] 301065 0
Define nutrition status of participant cohort. Nutritional status will be measured by albumin, vitamin D, iron status, IGF-1, BMI, body composition (as measured by bioimpedance analysis and skin fold thickness).
Timepoint [1] 301065 0
Assess at start of intervention, every 2 weeks during 8 week intervention and then after 3 and 6 months
Secondary outcome [2] 301066 0
Document remission rate following exclusive enteral nutrition. Remission of disease will be defined as a Crohn's disease activity index (CDAI) of less than 150 or a drop of more than 100 points. CDAI will be measured at baseline, after 4 weeks and after 8 weeks.
Timepoint [2] 301066 0
After 4 weeks and at end of the 8 week intervention
Secondary outcome [3] 301067 0
Document changes in nutritional markers following exclusive enteral nutrition. Serum albumin and IGF-1, weight, bioimpedance analysis skin fold thickness will be measured as markers of nutritional status.
Timepoint [3] 301067 0
Assess at start of intervention, every 2 weeks during 8 week intervention and then after 3 and 6 months
Secondary outcome [4] 301068 0
Assess the impact of exclusive enteral nutrition upon quality of life and disability scores. Quality of life will be measured using the IBDQ and disability will be measured using the Disability Index.
Timepoint [4] 301068 0
Assess at start of intervention, every 2 weeks during 8 week intervention and then after 3 and 6 months

Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients who meet study inclusion criteria will be informed about study and given the opportunity to take part. Patients who do not want to use exclusive enteral nutrition for whatever reason will be encouraged to use standard therapy of corticosteroids but take part in the study as a convenience control group

Summary
Brief summary
The purpose of the study is to investigate whether the benefits of exclusive enteral nutrition (a liquid diet) seen in paediatric populations can be replicated in adult populations. The study hypothesis is that a liquid diet changes markers of gut inflammation in adults with newly diagnosed Crohn’s disease leading to clinical and biochemical remission of Crohn’s disease.
