Date Title Trial type Completed Diets Sponsor Summary Excerpt Trial
Oct 2017 Personalized Research on Diet in Ulcerative Colitis and Crohn's Disease (PRODUCE) Interventional ✔ SCD, mSCD Children's Hospital Medical Center, Cincinnati A series of N-of-1 trials will be used to determine the effectiveness of a specific carbohydrate diet (SCD) versus a modified SCD in patients in reducing symptoms and inflammatory burden at both the individual and population level. This is a three-year study. The study staff will recruit 120 patients (goal sample size of 100, accounting for attrition) across up to 12 sites in patients aged 7-17 with mild to moderate disease activity. Randomized, open label, crossover trial.
Feb 2018 Combined Nutritional Therapies for the Treatment of Ulcerative Colitis Interventional AB Biotics, SA The study will include two groups of 20 patients each. One of the groups will receive 6 grams of fiber a day in a single shot with the main meal (group 1) and the other group will receive 12 grams of fiber a day divided into two meals with the main meals (group 2). Two different combinations of fibers (formula A and B) will be tested with the following administration pattern for both groups. Description of the administration pattern Week 1: Formula A Week 2: Formula A Week 3: Formula B Week 4: Formula B A second sequential cycle similar to the first one (4 weeks with the same administration pattern) will be repeated in order to confirm the reproducibility of the findings. The two formulas contain fibers known and commonly used in human nutrition, which were previously tested in in vitro models with human faeces and their ability to promote the growth of butyrate-producing bacterial species that are deficient in patients with colitis was proven ulcerative (Faecalibacterium prausnitzii and Roseburia hominis). The fibers are presented in aluminum envelopes to dissolve in a glass of water, juice, infusion or cold cream (max 37 ° C). In addition, formulas A and B for group 1 (a single intake per day) include the mixture of probiotics i3.1 in quantity per envelope of 3e + 9 colony-forming units, which contains: Pediococcus acidilactici CECT 7483, Lactobacillus plantarum CECT 7484 and Lactobacillus plantarum CECT 7485 in a 1: 1: 1 ratio.Randomized, open label, n=40
Mar 2018 Chronic Inflammatory Disease, Lifestyle and Risk of Disease (PROCID-DHC) Interventional University of Southern Denmark The study will use data from all of the 57,053 participants in the Danish cohort "Diet, Health and Cancer (DHC)" together with registry data. Blood samples, anthropometric measures and questionnaire data on diet and lifestyle were collected at the DHC study entry. The National Patient Registry (NPR) will be used to obtain to identify patients with CID during follow-up. Follow-up information on death and immigration will be collected in March 2018 from the Danish Civil Registration Register. The outcome of Chronic Inflammaroty Diseases (CID) is defined as at least one of the following CIDs: Crohn's disease, ulcerative colitis, psoriasis/psoriatic arthritis, rheumatoid arthritis/ankylosing arthritis, or multiple sclerosis, during the follow-up period from 1993 to March 2018. The primary hypothesis is that "the risk of CID will be significantly higher among those with a low fibre/high red and processed meat intake compared to those with a high fibre/low red and processed meat intake." Based on previous research on a shared etiology in CIDs a second hypothesis is that "the postulated causality between low fibre/high red and processed meat intake and risk of developing CID is applicable for each of the CID-diagnoses." Observational, prospective, 24 years, n=57,053
Mar 2018 The ENIGMA Study: Eastern Inflammatory Bowel Disease Gut Microbiota Observational Chinese University of Hong Kong The ENIGMA project comprises three main enteric microbiome domains of central importance to Crohn's disease. Two specific organisms which may play a critical role in disease pathogenesis, including the candidate protective bacterium, and the novel pathogenic candidate, will be characterised and studied in detail. Microbial findings will be related to detailed assessment of environmental factors that permit microbial changes or expression. Observational cohort, n=1300
Apr 2018 Reverse Engineering of Exclusive Enteral Nutrition (RE-EEN) Interventional EEN Dale Lee This will be an open label, pilot study over 4 weeks in children with newly diagnosed Crohn's disease treated with a smoothie designed to emulate formulas used for exclusive enteral nutritional therapy. In place of formula, whole-foods based smoothie recipes and the food to create the smoothies will be given to each participant/family. The smoothies will be based upon the concept of reverse-engineering of exclusive enteral nutrition (RE-EEN). The smoothie recipes will involve whole foods that can be blenderized to liquid consistency. Similar to the formulas used for EEN, the smoothies will provide calories, protein, fat, and carbohydrates in a distribution to support growth and development. Patients will be evaluated for induction of remission and changes in microbiome. Open label, n=10
Jul 2018 Immunonutrition in Ulcerative Colitis Interventional Baptist Memorial Health Care Corporation This study tests the hypothesis that a supplement that combines a functional fiber, long chain omega-3 polyunsaturated fatty acids (PUFAs), vitamin D3, vitamin E, and zinc will reduce clinical symptoms, decrease pro-inflammatory cytokines in the blood and ergo decrease inflammation, promote beneficial microbial activity in the colon, and help recovery of the intestinal mucosa of ulcerative colitis (UC) patients compared with a placebo. Randomized, single masked, n=30
Aug 2018 The Influence of a Fasting Mimicking Diet on Ulcerative Colitis Interventional Stanford University This research investigates whether markers of inflammation decrease and/or quality of life increases after three cycles of a five-day period of the fasting mimicking diet, and may provide rationale for its use to treat UC. Three cycles of a 5-day reduced calorie diet over 3 months. Primary outcome; changes in CRP, FCP, ESR. Secondary outcome: clinical remission per Mayo score, endoscopic outcomes. Other outcomes: measure of additional inflammatory markers, changes in gut metabolites and microbiome profiles. Open label, n=75
Feb 2019 The MELODY Trial: Modulating Early Life Microbiome Through Dietary Intervention in Crohn's Disease
 Interventional IBD-AID Icahn School of Medicine at Mount Sinai The goal of this study is to prospectively test the hypothesis that a non-invasive dietary intervention during the last trimester of pregnancy could beneficially shift the microbiome of CD and UC patients and their babies, hereby promoting a healthier immune system during a critical time of the immune system development. Particularly, the study team will test whether favorable diet-driven changes in the microbiome can lead to a reduced risk of postpartum relapse and lower gut inflammation in the offspring. The study design is a three-arm, prospective, pre-post intervention trial. Crohn's Disease (CD) patients at 27-29 weeks of pregnancy will self-select to Arm 1 or Arm 2. Controls will be in Arm 3. Arm 1 (diet-CD): 8-10 weeks of dietary intervention (n=66) Arm 2 (no-diet-CD): usual diet with no intervention (n=66) Arm 3 (no-diet-control): unaffected controls at the same gestational stage will follow their usual diet and no intervention (n=66). This study has been updated to include mothers with UC in addition to mothers with CD.
May 2019 Inflammatory Bowel Disease Tracker (IBD Tracker) (IBDTr) Observational Massachusetts General Hospital The goal for this study is to use non-invasive monitoring techniques to identify biomarkers that emerge, or change predictably, when a patient begins to relapse from remission to enter a period of disease - to find the earliest signs of an active flare. If the investigators identify a pattern of biomarkers that could alert a patient and their clinician to a flare as soon as it begins, it may be possible to intervene before symptoms present by changing medication and/or diet and lifestyle to lessen the severity of the disease flare. The biomarker fingerprint may also reveal new targets for therapeutics that could control IBD. Patient reported well being, 24 hour dietary recall, Smart Watch monitoring for activity, sleep, movement. Blood, stool, urine biomarkers measured throughout 12 month period, as well as biospecimens for microbiome and metabolite composition. Observational, prospective, 12 months, N=100
Jul 2019 Vegetarian Diet in Ulcerative Colitis (LOVUC) Interventional Edith Cowan University To determine whether a lacto-ovo vegetarian diet is effective in improving gastrointestinal symptoms, quality-of-life, intestinal inflammation and gut microbiota composition in mild-to-moderate UC compared to a standard omnivorous diet. This study will review whether a lacto-ovo vegetarian diet is an optimal dietary therapy to achieve a clinical response in mild to moderate UC as an adjunctive treatment to current medical therapies. The proposed RCT will be used to evaluate the efficacy of a lacto-ovo vegetarian diet together with its effect on the microbiota to create an enhanced understanding of the role diet plays in the management of UC. Using a socially acceptable diet it is anticipated that food-related quality-of-life measures will improve for participants. Dietary modification could be a more economical, safer and more effective means of reducing symptoms and flare-ups compared to pharmacological therapy. Phase 1: Open labelled, single centre trial (10 patients) Phase 2: Open labelled, single centre, single blinded, randomised controlled clinical trial (n=30).

Sep 2019 Biomarker-based Multidisciplinary Team (Bio-MDT) Approach to Personalized Microbial-targeted Treatment of Pouchitis and Crohn's Disease (Bio-MDT) Interventional SCD Rabin Medical Center We hypothesized that personalized antibiotics and dietary interventions will modify microbial composition and result in significantly improved outcomes, specifically resolution of inflammation and prolonged remission rates in patients with a pouch. Aims: 1. Compare the effect of two antibiotic treatments on clinical, inflammatory and microbiological outcomes of patients with pouch inflammation. 2. Evaluate the effect of combined microbiome-targeted antibiotic and dietary intervention as treatment and prevention strategy in patients after pouch surgery. 3. Evaluate the effect of a microbiome-targeted dietary intervention as prevention strategy in patients after pouch surgery. 4. Identify predictors for response to specific antibiotic and dietary interventions.
