Active clinical trials for "Crohn Disease"

The objectives of the study are to evaluate the safety and tolerability of oral administration of MB-102, and to evaluate the use of MB-102 as a means of measuring gut permeability in normal participants (n=10) and in those with radiologic evidence of small bowel Crohn's disease (n=10).

Crohn's disease (CD) presents with severe symptoms, but fatigue is a very predominant symptom that negatively impacts upon quality of life. Fatigue affects ~40% of patients when well and 80% of patients when the disease is active. It is the second commonest symptom that an IBD patient gets throughout their life-time. The IBD priority-setting partnership between the James Lind Alliance and the British Society of Gastroenterology has recently identified fatigue as an area of unmet clinical need and a priority research field, in which diagnosis and therapeutic intervention are lacking. Based on other diseases that present with fatigue, the cause of fatigue may be divided into peripheral fatigue, mainly driven by anomalies in muscle mass and function and central fatigue, mainly driven through decreased blood supply to the brain during exercise probably due to decreased heart and lung fitness. Research in IBD fatigue until now has been patchy with no convincing evidence that any treatment helps. There has been no research aimed at studying whole body function. It is imperative to have a better understanding of the alterations in muscle, brain, heart and lung function seen in these patients before specific treatments are researched. In this study, the investigators aim to recruit 32 CD patients, half with fatigue and half without. Subjects with active disease or with other known reasons of fatigue will be excluded. Findings in this group will be compared to 16 other healthy control volunteers of a similar age, gender and Body Mass Index. The study aims to recruit all participants over 36 months, and will target people aged from 16 to 60 years of age. Once recruited, the participants will be asked to provide their consent to take-part in 3 experiments on two separate days. These experiments have been designed to carefully consider potential fatigue burden, experimental practicality, and participant availability. Objective 1: The investigators aim to measure muscle fitness and strength by asking subjects to exercise using a stepper, whilst body mass and composition will be measured using an X-ray. This session will take 2 hours and be undertaken on one day. Objective 2: Peripheral fatigue: The investigators aim to non-invasively measure the recovery of muscle physiology after exercise by using magnetic resonance imaging after 5 min of exercise undertaken with a limb cuff. This will take ~1 hour. Objective 3: Central fatigue: while in the scanner and performing exercise, the investigators aim to non-invasively measure heart and brain blood flow before and after a few minutes of exercise using magnetic resonance imaging. This will take 2 hours. Experimental work for Objectives 2 and 3 will be undertaken on the same day. There will be ample time for recovery in between and during the different studies. There will be no further commitment from the participants required after these 2 study visits. IBD fatigue has never been studied in such detail. This unique work will allow identification of fatigue mechanisms, which can then be targeted with exercise, nutritional, or medical treatments.

NCT02108821 Primary goal: -To determine the safety of fecal transplant by colonoscopy and retention enemas for induction followed by maintenance retention fecal vs. placebo enemas in children and young adults with uncomplicated mild-moderately active Crohn's disease. Secondary goals: Assess efficacy of this induction regimen followed by maintenance fecal or placebo transplants in responders. The efficacy will be assessed by clinical evaluation and fecal calprotectin that is a non-invasive biomarker. Correlate subject's baseline microbiome findings with likelihood for response to FMT induction therapy. Follow the chronological microbiome shifts after transplant and correlate with response using clinical and calprotectin assessment in the two groups.

This Phase 2a, multicenter, randomized, double-blind, placebo-controlled study examines subcutaneous dose of PF-06480605 150 mg administered every 4 weeks in participants with moderate to severe active Crohn's Disease to characterize safety, efficacy, pharmacokinetics, and immunogenicity

This is a phase 2, randomized, double-blind, multicenter study to assess the therapeutic efficacy, safety, and mechanisms of omilancor (BT-11) in patients with moderate to severe Crohn's Disease (CD).

The purpose of this study is to assess the ability of a whole-food, plant-based (WFPB) diet to produce symptomatic remission in Crohn's Disease patients.

The purpose of study is to test the effect of an experimental medication GED-0301(mongersen) and evaluate its safety in patients (≥ 12 years of age) with active Crohn's disease. The study will test GED-0301 compare to placebo for 12 weeks. The study treatment is blinded which means that patients and the study doctor will not know which treatment has been assigned. Patients in this study will be allowed treatment with stable doses of oral aminosalicylates, oral corticosteroids, immunosupressants and antibiotics for the treatment of Crohn's disease. Adolescent patients will also be allowed treatment with stable doses of exclusive enteral nutrition and growth hormone. All patients who complete the study will have the option to enter a long term active treatment study.

It is assumed that gut inflammation and lesions characterizing flares of Crohn's disease (CD) result from an aberrant T-cell mediated immune responses characterized by a complex balance between peripheral and lamina propria regulatory and effector T cell subsets. Because most of CD patients who undergo a surgery experienced a postoperative endoscopic recurrence of the disease (70 % at one year) leading to a clinical recurrence (10 % per year), the "model" of postoperative recurrence in CD represents a privileged situation that mimicks what happens in the gut of CD patients in clinical remission before the occurrence of further flares. It is likely that the same factors which underlie the immunopathogenesis of CD at its early stages also contribute to disease recurrence in the postoperative setting. Indeed, the postoperative state is performed for intent of disease remission and this situation represents probably an ideal setting to investigate the dynamics of most of T cell subsets in the peripheral and mucosal compartments because one may argue that removal of the diseased segment of bowel resets the disease to its earliest phases, providing an interesting window to better understand which T cell subsets predispose to disease recurrence. That is the reason why this model will be used in the present project i) to understand better the immunopathogenesis of CD relapse; ii) to identify novel and promising immune cell-associated biomarkers capable to predict relapse of the disease and finally iii) to identify potential specific therapeutic target associated with T cell subsets involved in the initiation of disease.

Anti-cytokine antibodies, such as Infliximab (an anti TNF alfa chimeric antibody) and Adalimumab (an anti TNF alfa humanize antibody), have been developed and used in clinical practice for the treatment of patients with Crohn disease (CD). Unfortunately, their efficacy is limited. Based on these concepts, a new drug has been developed for IBD treatment. Vedolizumab (VDZ) is able to recognize the α4β7 heterodimer, and selectively blocks gut lymphocyte trafficking. The hypothesis of this study is that VDZ therapy may be to halt CD disease progression during time and modifying its natural history, using Lemann Index.

This is a multicenter, Phase 1b, randomized, double-blind, placebo-controlled, sequential-cohort, multiple ascending dose (MAD) study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of 3 subcutaneous and 1 intravenous dose of E6011 in subjects with active Crohn's disease (CD). Thirty-two subjects will be randomized to one of 4 dose cohorts (8 per cohort) and will receive E6011 or placebo for 10 weeks. The first 3 cohorts will receive E6011 or placebo via subcutaneous injection and the last cohort will receive E6011 or placebo by intravenous injection. The ratio of E6011 to placebo within each cohort will be 3:1. The study has 2 phases: Prerandomization and Randomization.
