Inflammatory bowel disease clinical trials — recruiting now

This research aims to evaluate the long-term recurrence risk of perianal fistulas in Crohn's disease patients who have undergone treatment with anti-TNF therapy and seton drainage.The research seeks to identify factors influencing recurrence and assess the long term effectiveness of these treatments in preventing fistula recurrence. This study will provide insights that could enhance treatment strategies and improve patient outcomes.

The CELESTE cohort will be a three-center prospective cohort associated with the creation of a biobank including Inflammatory Bowel Diseases (IBD) patients with active disease

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). This study will assess the change in disease activity of risankizumab treatment in adult participants with moderate to severe UC in real-world clinical practice. Risankizumab is an approved drug for treating participants with ulcerative colitis. Approximately 200 participants who are prescribed risankizumab by their physician in accordance with local label will be enrolled in approximately multiple sites across Germany and Austria. Participants will receive risankizumab as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 52 weeks. There is expected to be no additional burden for participants in this trial. Participants will attend regular visits during the study at a hospital or clinic according to their routine clinical practice.

The goal of this clinical trial is to learn if statins work to prevent strictures in adults with Crohn's disease. The main question it aims to answer is: * Can statins reduce the formation of strictures in participants with stricturing Crohn's disease? Researchers will compare statins to a placebo (a look-a-like substance that contains no drug) to see if statins work to prevent strictures from forming. Participants will: * Take statins or a placebo every day for 6-12 months * Visit the clinic for lab tests twice after starting either statins or placebo * Complete questionnaires about symptoms and medications * Respond to monthly check-ins (via phone call) during participation

This international multicentre prospective study aims to develop a new simple score using enhanced endoscopic techniques which focus on the vascular features of the colon and reliably distinguish between a quiescent and a mild inflammation in ulcerative colitis (UC). The diagnostic performance of the new score in defining disease activity/remission compared to existing endoscopic and histological scores and predict long-term clinical outcomes will be evaluated. The study also aims to adapt current artificial intelligence (AI) algorithms for enhanced endoscopic techniques to improve standardization in UC disease assessment and outcome prediction.

The purpose of the study is to evaluate the safety, efficacy, and pharmacokinetics of AC-101 tablets in participants with moderate-to-severe ulcerative colitis. The total study duration is up to 17 weeks, including 4-week screening, 12-week treatment period, and 1-week safety follow-up. The study will enroll approximately 24 participants with moderate to severe active ulcerative colitis.

This is a randomized, double-blind, placebo-controlled, multicenter, study to evaluate the efficacy, safety, and pharmacokinetics (PK) of budesonide extended-release tablets for the induction of remission in pediatric subjects, with active, mild to moderate ulcerative colitis (UC). Subjects will be permitted to continue taking background oral or rectal 5-aminosalicylate (5-ASA) products.

The goal of The BEGIN Study, a randomized controlled double-blinded intervention trial, is to learn if probiotics, with Bifidobacterium longum subspecies infantis Bifin02 (B. infantis), given to healthy newborns can affect various health outcomes and to explore impacts of the infant gastrointestinal microbiome. The main questions it aims to answer are: * Does B. infantis probiotics impact immune function and does it lower the number of bacterial infections and use of antibiotics? * Does B. infantis probiotics impact overall health, development, growth and wellbeing? * Does B. infantis probiotics impact inflammatory diseases, allergies and autoimmune diseases Researchers will compare B. infantis probiotics to a placebo (a look-alike substance that contains no probiotic) to see if B. infantis colonization impact the human immunesystem and various clinical and biochemical health markers. Participants (parents) will * Orally administrate the B. infantis probiotic to their newborn child daily in three weeks from 7 days of age. * Answer baseline and follow up questionnaires in a study app * Take five stool samples from the child and one stool sample from the mother * Collect a 4 week of passive dust sample at home (Electrostatic Dust fall Collector) * Donate one dried bloodspot and one blood sample from their child

Crohn's Disease and Ulcerative Colitis are two types of inflammatory bowel disease (IBD), which is a serious, long-term condition in the gut (intestine) that can cause pain and swelling (inflammation) in the bowel. TAK-279 is a medicine which helps to block inflammation. This study is an extension of the parent studies, TAK-279-CD-2001 (NCT06233461) and TAK-279-UC-2001 (NCT06254950). This means that participants who responded to treatment with TAK-279 in either of the parent studies may be able to continue to benefit from the treatment in this study. The main aim of this study is to find out how safe TAK-279 is for long term use and to check if it reduces bowel inflammation and symptoms when used for a longer period of time in adults with moderately to severely active UC or CD. The participants will be treated with TAK-279 for up to 2 years (108 weeks). During the study, participants will visit their study clinic 11 times.

The purpose of the study is to ascertain whether traditional kefir not only enhances vascular health but also contributes to improved immune outcomes in both male and female participants at higher risk or living with Type 2 Diabetes (T2D) after 12 weeks of treatment.

Pediatric Ulcerative Colitis (UC) patients with moderate to severe disease activity at high risk of colectomy. Early use of biologic agents will likely be more effective. But there were no studies identified that compared a strategy of upfront biologic-based therapy versus gradual step-up therapy. In our study, newly diagnosed moderate to severe pediatric UC patients (6-18 years old) will be randomly divided into infliximab (IFX) treatment group (Top down group, TD) and corticosteroids (CS) treatment group (Step-up group, SU). Mucosal healing rate at week 12 will be compared between the two groups. The relapse rates and sustained durations of remission within one year will also be evaluated.

The purpose of this study is to evaluate how-well icotrokinra works (clinical efficacy) and how safe it is (safety) in participants with moderately to severely active Crohn's disease (CD; a long-term condition causing severe inflammation of the intestinal tract).

The primary objectives of this project are twofold: firstly, to evaluate the role of Maifu Changqing® Complete Nutrition Formula Powder in bowel preparation for colonoscopy in patients with IBD; and secondly, to enhance the nutritional support and comfort of bowel preparation for IBD patients.

The purpose of this study is to see how a diet that mimics fasting effects inflammation in patients with mild to moderate Ulcerative Colitis (UC). The diet may allow users to receive the benefits of fasting while also being able to enjoy food (the ingredients of which are GRAS (generally recognized as safe) by the Food and Drug Administration (FDA). Research on dietary interventions and UC are very limited. Fasting mimicking diets (FMD) have been studied with support of the National Institute of Health and published in leading journals. 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.

Alcohol use disorder (AUD) has been associated with high prevalence of inflammation-associated co-morbidities in people living with HIV even those receiving effective antiretroviral therapy (ART). Our preliminary data support a model in which the combined insult of AUD and HIV on the gut, specifically on the microbiota and intestinal barrier integrity, exacerbates inflammation. Our preliminary data using intestinal organoids also suggest a potential mechanism for AUD-mediated changes in the gut barrier function during HIV; the intestines of HIV+ individuals have low resilience to alcohol induced intestinal barrier disruption caused by high levels of oxidative stress. Finally, our preliminary data also suggest a potential approach to enhance the integrity of the intestinal barrier and reduce gut derived inflammation in people living with HIV with/without AUD- short chain fatty acid prebiotics. These prebiotics prevent alcohol mediated adverse effects on the intestinal barrier and inflammation by preventing oxidative stress. These prebiotics are safe and decrease gut inflammation in humans. 20 HIV+ ART+ (10 AUD- and 10 AUD +), will be recruited for a prebiotic intervention. This is a proof-of-concept observational study to establish a causal link between microbiota-gut and HIV pathology during ART by asking whether modifying microbiota and gut milieu impacts intestinal barrier function, systemic inflammation, and brain pathology in HIV+ people. Participants will have two study visits, where stool collection and blood draw will be collected, as well as questionnaires. These participants are part of the larger observation study (n=160), which will test the hypothesis that intestines from HIV+ individuals have lower resilience to alcohol mediated gut barrier disruption than intestines from HIV-negative controls. We will recruit the following groups of participants: HIV+ ART+ AUD-; HIV+ ART+ AUD+; HIV- AUD- ; HIV- AUD+. Blood, urine, stool, and intestinal biopsies will be collected from participants to compare intestinal barrier integrity, system and gut inflammation, immune activation, oxidative stress, microbiome/metabolome. and HIV reservois. Second, lleal/colonic organoids from HIV- and HIV ART+ individuals will be generated to examine their resilience to alcohol-induced intestinal barrier disruption.

Crohn's Disease (CD) is a chronic inflammatory condition that can affect any part of the intestine and currently has no cure. It affects 6.8 million people worldwide with UK healthcare costs in excess of £1 billion per year. Recent data suggests that the despite significant progress in treatments over the last 2 decades to help control disease, up to half of patients still develop progressive bowel scarring that require surgery and up to 70% needing surgery within 10-20 years from diagnosis. Unfortunately this is not a cure and some still require repeat surgery. These features have a devastating impact on an individual including education, work and social life. All our current treatments focus on resolving inflammation but there are no treatments targeting fibrosis, its activity and its progression. A major hurdle in our progress towards anti-fibrotic treatments and advancing care in CD has been our inability to identify bowel scarring accurately using non-invasive tests; this being critical in developing new treatments that prevent permanent bowel damage. We are also unable to identify early stage scarring (fibrosis) and once established we are unable to differentiate between different stages of scarring severity. The investigators aim to investigate a novel method that can identify early scarring and track progressive bowel damage by tracking cells that cause fibrosis. In this study the investigators will use a 'dye', also known as fibrosis associated protein inhibitor (FAPI), that tracks scarring and its activity in the intestine. The presence and amount of FAPI within an area of scarring can be detected using our current imaging tests (positron emission tomography and Computer Tomography imaging: PET/CT). If successful, this study will be the first method for detecting scarring activity in CD and have the potential to revolutionise care for this condition and facilitate new drug development to halt the processing of scarring (fibrosis) and improve the outcomes for patients with CD.

The aim of this project is to start a biological and clinical collection of patients presenting systemic autoimmune disease. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies

The cause of inflammatory bowel disease (IBD) is currently unknown, although partly attributed to interactions among genetic risk polymorphisms, environmental factors, gut microbiome, and host immunity. Diet, particularly those with plant-based products, have been shown in prior research to improve gut microbial composition, which has been linked to different IBD-related outcomes. This study is interested in evaluating the impact of prebiotics on gut microbiome composition and gut health in patients with IBD. Dietary composition will be assessed at baseline and over the course of 16 weeks. Participants will be randomized to either consume an 8-week course of prebiotic supplementation beginning at week 0 or week 8. Stool samples will be collected at weeks 0 and 8. The stool will be analyzed for cross-sectional and longitudinal fecal microbial changes associated with different prebiotic and diet consumption patterns in the context of heterogeneous disease characteristics.

With this prospective, randomized, multicentre, parallel group pragmatic non-inferiority trial, the investigators will evaluate if endoscopy-driven introduction of biological therapy is not leading to more postoperative endoscopic recurrence at week 86 compared to systematic prophylactic biological therapy in patients with CD undergoing an ileocolonic resection with ileocolonic anastomosis. Secondary analyses will include influence on clinical, biological and surgical CD recurrence, serious adverse events, direct costs, work productivity, and quality of life. If the investigators can demonstrate the non-inferiority of an endoscopy-driven approach, this patient-tailored management could be advocated, while a more expensive systematic introduction of biological therapies could be limited. Finally, endoscopic images provided through the SOPRANO CD study, will be used to develop a new scoring system evaluating postoperative endoscopic recurrence.

Researchers want to learn more about tulisokibart (also known as MK-7240) in an extension study. Tulisokibart is a medicine designed to treat active, moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). An extension study is a type of study where people who received tulisokibart in certain other studies for CD or UC (called a parent study) may be able to join this study. The goals of this study are to learn about the safety of tulisokibart over time in people with CD or UC, and if people tolerate it.
