NCT03681652
Objectives: To examine the effect of prophylaxis therapy on clinical and endoscopic disease recurrence in children with Crohn's Disease (CD) following ileo-cecal resection. Hypothesis: Post-operative pediatric patients treated with anti-Tumor necrosis factor (TNF) prophylaxis will demonstrate lower endoscopic recurrence rates at 1 year and lower clinical recurrence rates at 2 years compared with thiopurines treated patients. Design: A multi-center, prospective, observational study. Patients with either thiopurines or anti-TNF prophylaxis will be enrolled 0-6 months following ileo-cecal resection. Prophylactic treatment will be decided at the discretion of the treating physician and not as a part of the study. According to standard-of-care, patients will undergo a colonoscopic evaluation 6-9 month following surgery. Study visits will be performed at 6 months following resection, 12 months, 18 months and 24 months. Setting: Porto group and IBD interest group pediatric gastroenterology centers. Participants: Children 6 year to 18 years (Overall, 84 patients) with CD following limited ileo-cecal resection. Main outcome measure: 1. Endoscopic recurrence at 1 year (according to Rutgeerts Score: i2-i4). 2. Clinical recurrence at 2 years (according to pediatric Crohn's disease activity index-PCDAI: ≥10). Secondary outcome measures: 1. Re-operation rate at 2 years. 2. Exacerbation-free quartiles at 2 years. 3. Anthropometric and laboratory measures including calprotectin at each visit. 4. Changes in fecal microbiome- baseline, 1 year and 2 years. Inclusion criteria: 1. CD with phenotypes L1 and L3 following ileo-cecal resection. 2. No active perianal disease. 3. Prophylactic therapy with either thiopurines or anti-TNF. Exclusion criteria: 1. Pregnancy. 2. Active perianal disease (draining fistula or abscess). 3. Post-operative intra-abdominal complication (fistula or abscess). Sample size: In order to demonstrate 20% difference in endoscopic recurrence rate between groups is significant, we will need to study 42 children in each group to be able to reject the null hypothesis that the failure rates between the groups are equal with probability (power) of 80% and a type I error probability of 0.05.

NCT05039411
Objectives: Primary: To demonstrate the safety of allogeneic UC-MSCs administered by injection for complex perianal fistulas in patients with Crohn's disease Secondary: To determine the efficacy of a single/multiple allogeneic UC-MSCs injection in improving complex perianal fistula complications and (re-epithelialization of the external openings).
NCT03266484
The study is proposed as a single-site randomized double-blind placebo-controlled trial requiring 4 study visits, where two of the visits are combined with their appointment for routine clinical care. The study population will consist of patients with quiescent CD and UC and IBD-unspecified recruited from the Massachusetts General Hospital Crohn's and Colitis center. All eligible subjects will have a confirmed diagnosis of CD, UC, or IBD-unspecified according to accepted clinical, endoscopic, radiologic, and histologic criteria. Eligible patients will be contacted at the time of their routinely scheduled office visit and consented for the study. Self-report and review of medical records will be used to obtain detailed information regarding their disease on an intake questionnaire completed by a research study coordinator. The study is proposed as a 12-week double-blind randomized controlled trial of the probiotic supplement compared to placebo. We propose to examine the effect of a specific probiotic supplement on the changes in the gut microbiome, serum metabolomic profile, and fatigue symptoms in patients with quiescent IBD. Within 2 weeks of screening, eligible patients will be invited to visit MGH for a baseline visit. The patient will receive either the probiotic supplement or placebo for 4 weeks. The first follow up visit will be at week 4 to check for adverse events on study treatment, to check accountability of probiotics/placebo, and to complete the set of questionnaires. Also, subjects will receive probiotic/placebo samples for the remaining 8 weeks of treatment. At week 8, subjects will receive a phone call from a study research coordinator to check in with probiotics/placebo intake for treatment compliance and accountability records, and to complete the set of questionnaires ascertaining subjective symptoms. Last study visit will be at week 12 which is often combined with a regular office appointment. Subject will provide serum blood and stool sample, as well as complete the set of questionnaires.
NCT06961942
Endoscopic scoring systems are vital for the objective assessment of disease activity being used in both clinical trials and daily clinical practice. These standardized scoring systems are essential for diagnosing, evaluating endoscopic healing, monitoring treatment response, and predicting clinical outcomes. One of the primary challenges in implementing these scoring systems is inter-observer variability, as highlighted by significant discrepancies between scores assigned by local and central reviewers. However, the performance of these systems among experts has been shown to be excellent, suggesting that achieving consistent and accurate scoring requires a high level of exposure and proficiency. Inconsistent scoring, especially among less experienced clinicians, poses a challenge to the reliability of these scoring systems. The primary objective of this study is to evaluate the improvement of scoring accuracy after training with structured educational videos with a specific focus on the learning curve and the practical application of endoscopic scoring systems.
NCT06750731
The goal of this observational study is to assess the feasibility and effectiveness of a remote monitoring digital health system on adherence, clinical outcomes, and healthcare utilization in patients with inflammatory bowel disease (Crohn's disease, ulcerative colitis, and inflammatory bowel disease type undetermined) initiating therapy with vedolizumab (Entvyio). The main questions it aims to answer are: 1. Assess and compare adherence to intravenous (IV) and subcutaneous vedolizumab maintenance therapy in patients with IBD using a novel remote monitoring system. 2. Assess symptom response to vedolizumab post induction (week 6-8) and during maintenance therapy (week 22) using a novel remote monitoring system. 3. Assess time to response to vedolizumab during induction (weeks 0-6) using a novel remote monitoring system. Researchers will compare medication adherence between participants using IV and subcutaneous vedolizumab maintenance therapy to see if adherence is lower with self-administration. Participants will be asked to register adherence to medication using the novel remote monitoring system each time they take a dose of vedolizumab and to respond to two questions about bowel symptoms weekly for the first 6 weeks after starting vedolizumab then monthly thereafter for 6 months. Additionally, participants will be asked to enter information regarding demographics and social determinants of health at baseline and other variables listed below at baseline and at weeks 2, 6, 14, and 22 post baseline unless otherwise denoted: * MARS-5 * Healthcare utilization (22 weeks only) * Harvey Bradshaw Index (Crohn's disease only) * Simple clinical colitis activity index (Ulcerative colitis only) * PROMIS Global Health Scale * PROMIS Anxiety * PROMIS Depression * PROMIS Sleep Disturbance * PROMIS Pain Interference * PROMIS Physical Function * IBD Self-Efficacy * Attitudinal Survey (22 weeks only)
NCT05253378
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD). Like other chronic diseases, patients with CD may be affected by other diseases called comorbidities. The prevalence of comorbidities in IBD patients ranges from 30 to 70 %. Unlike other chronic diseases, there is currently no CD-specific tool to assess the impact of comorbidities on patients' lives in order to take appropriate medical measures. Several clinical indexes have been developed for the study of comorbidities, including the Charlson index and the Groll index, which are widely used. The disadvantage of these indexes is that they are not adapted to patients with CD. The primary objective of this study is to develop and validate a clinical index to evaluate the impact of comorbidities on disability in patients with CD.
NCT06892990
In the context of the COLORIZE study, it is being tested whether the endoscopic light mode Texture and Color Enhancement Imaging (TXI) is non-inferior to the standard White Light Endoscopy (WLE) in assessing inflammatory activity in patients with Inflammatory Bowel Disease (IBD). For this purpose, ileocolonoscopy is performed on patients diagnosed with IBD, and standardized image documentation will be carried out in both WLE and TXI modes. Step biopsies are taken, and clinically validated, endoscopic, and histological scores are used.

NCT06104631
Crohn's disease is a chronic and complex inflammatory bowel disease affecting the gastrointestinal tract, causing symptoms like abdominal pain, diarrhea, and fatigue. While its exact cause is unclear, it involves genetic, environmental, and immunological factors. Crohn's disease can lead to nutrient deficiencies and has unpredictable flare-ups and remission periods. During the remission phases, irritable bowel syndrome (IBS)-like symptoms can persist in 50% of patients, for which no satisfactory treatment is available yet. Chitin-glucan is prebiotic, obtained by extraction, isolation and purification from a fungal resource: the mycelium of Aspergillus niger (a microscopic fungus of the Ascomycetes family) of which it composes the cell walls. The biopolymer consists essentially of two types of polysaccharide chains: chitin (poly-N-acetyl-D-glucosamine) and beta-(1,3)-D-glucan (D-glucose units linked essentially via beta-1,3 bonds). Because of its beta bond, human intestinal enzymes cannot digest it, as a result, the majority of chitin-glucan can reach the colon where it can be fermented by the microbiota. By modulating the composition and/or activity of the intestinal microbiota, fermentation of chitin-glucan could have beneficial effects on health. The aim of the RELIEVE study is to assess if BK003 could improve the relief of global symptoms, individual symptoms, stool consistency and frequency of evacuations, quality of life, anxiety, and depression in patients with Crohn's disease in remission without treatment or with stable maintenance therapy and having IBS-like symptoms and to confirm the product's safety.

NCT04239248
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.
