Active clinical trials for "Crohn Disease"

The purpose of this study is to evaluate the effectiveness of ustekinumab in achieving clinical remission in pediatric participants (greater than or equal to [>=] 2 to less than [<] 18 years and weight >= 40 kilograms [kg] at baseline).

The purpose of this study is to assess the long-term safety of vedolizumab versus other biologic agents in participants with Ulcerative Colitis (UC) or Crohn's Disease (CD).

This study is a non-interventional, observational study of Humira® in the treatment of pediatric CD as per the New Drug Re-examination Guideline in Korea. This study will be conducted in institutions which provide a written agreement to AbbVie Korea, and where the use of Humira® for pediatric CD is following their normal medical practice setting. Pediatric patients who are prescribed Humira® as per physician's medical judgment in accordance with the approved Korean local label will be enrolled in the study. As this is a post marketing surveillance, AbbVie is NOT involved in the product supply since the drug is being used according to the approved marketing label and is to be prescribed by the physician under usual and customary practice of physician prescription.

The perianal lesions (LAP) specific for Crohn's disease have been reported in 1938, six years after the first cases of luminal disease. If phenotypic data of the latter are well documented today, those of perianal disease remain inadequately described. The reasons are numerous: understated symptoms by patients, elementary semiotics proctology ignored by practitioners, lack of validated classifications to track these violations and challenges to undertake clinical trials to high standard of proof in view of these variables, etc. ... Moreover, the impact of these LAP varies across studies (10-80%). in addition to the above-mentioned reasons, these results are also due to the different definitions of LAP used in the studies, their collection in reference centers versus tertiary centers, their potential occurrence at any time of disease progression, their greater frequency in case of distal disease (12% for infringement isolated ileal, 15% in breach ileo colic, 41% in case of colonic involvement and 91% in case of rectal involvement). Yet the specific LAP should be better documented because they are a factor of poor prognosis of Crohn's disease.

The aim of this study will be to show a decrease in postoperative morphine consumption by the practice of perioperative self-hypnosis in patients undergoing laparoscopic ileo-caecal resection for Crohn's disease

HealthPROMISE is a mobile application (app) for patients that allows regular tracking of symptoms by patients and communicates them to physicians. The purpose of this randomized controlled trial is to determine the impact of the HealthPROMISE application on improving patient outcomes. The trial will look at how much patients use the application, whether physicians change treatment in response to new information from patients, and how the patients quality of life change over the span of the study. The investigators hypothesize that HealthPROMISE will enhance physician-patient communication and improve clinical outcomes.

The purpose of this study is to determine whether hemodynamic optimization with photoplethysmography (ClearSight, Edwards Lifesciences, Irvine, CA) during colorectal surgery could decrease the incidence of perioperative complications.

The utility of capsule endoscopy in diagnosing small bowel (SB) Crohn's disease has been demonstrated in a number of studies. Mucosal healing is a good predictor of long term remission. Unfortunately, the assessment of small bowel mucosal healing by conventional colonoscopy is an invasive technique which is not complete since it does not allow exploration of the small bowel beyond the terminal ileum (TI). Thus, direct evidence of the healing of the majority of the small bowel is lacking.

Ustekinumab is a fully human Immune Globulin Gk (IgGk) monoclonal antibody against the common p40 subunit of interleukin-12 and interleukin-23, which are implicated in the pathogenesis of inflammatory bowel disease. Its efficiency to induce and maintain clinical response in patients with anti TNF resistant Crohn's disease has been proved in several clinical trials, and the profile of safety of this treatment was good, but the investigators have few data about biological characteristics of patients treated by Ustekinumab, particularly about ustekinumab through levels and rate of patients developing anti ustekinumab antibodies during the induction and maintenance stages, and no predictive factors of clinical response have been identified yet. The aim of this study will be to assess the evolution of biological markers of inflammation and ustekinumab trough levels and antibodies, in responders and non responders patients treated by ustekinumab, in order to identify predictive factors of clinical response. The investigators will perform a prospective observational study, including the patients followed in the University hospital center of Lyon and treated by ustekinumab for a moderate to severe Crohn's disease (with a HBI score≥4 ). All the patients included will have been previously treated by at least one anti TNF and/or Vedolizumab, with specified criteria for a primary non response, a secondary loss of response or unacceptable side effects. Then, clinical and biological data will be collected for each patient at the inclusion, and then at weeks 4, 8, 16, 24: HBI score, sides effects, extra intestinal manifestations, steroids withdraw, CRP, calprotectin, ustekinumab trough levels and ustekinumab antibodies. The investigators will compare responding and non responding patients at week 16 (end of the induction period) according to these data. The hypothesis the investigators state is that an early and significant decrease of the inflammation markers in blood and stools associated with a high ustekinumab through level in blood is associated with a clinical response at week 16 in the patients treated by ustekinumab

A research team from King's College London are investigating how diet can be used as a treatment for Crohn's disease. The investigators have designed a new diet and eventually wish to test whether the diet can be used to manage Crohn's disease and reduce gut inflammation. Before doing this, the investigators need to find out how practical it is for people to follow the diet for 14 days by conducting this 'feasibility' study. A feasibility study is a small study that aims to highlight any issues before informing the design of a larger research trial. The diet the investigators have designed is called the Crohn's Diet. The evidence for this diet is based on recent research which suggests that certain food ingredients may be involved in triggering gut inflammation. The study's primary aim is to assess the practicalities of following the Crohn's Diet. It will also assess compliance to the Crohn's Diet and if following it changes the nutritional balance from the normal diet.
