Switching to the IL-23 Inhibitor Guselkumab for People With Active IBD Who Previously Used Ustekinumab (SHIFT-IBD)

The SHIFT-IBD Study is being conducted at multiple medical centers across Canada to evaluate how well guselkumab (Tremfya) works for people with inflammatory bowel disease (IBD) who haven't responded well enough to ustekinumab. Patients will begin guselkumab based on their doctor's decision. If eligible, they may be invited to participate in the study, which involves monitoring symptoms, test results, and overall health over the course of one year. Guselkumab will be given according to local medical guidelines. Doctors can adjust the treatment as needed, just like in routine care. Researchers believe that switching to guselkumab may be as effective as other advanced treatments. For those who saw some improvement on ustekinumab but not enough, guselkumab may offer better symptom control-without worsening results on medical tests like endoscopy. The goal is to explore better treatment options for people whose IBD has not been well controlled with current therapies.

Hyperbaric Oxygen Therapy for Perianal Fistulizing Crohn's Disease Not Responsive or Intolerant to Conventional Care: HYPNOTIC Pilot Study

This study aims to test a new treatment called hyperbaric oxygen therapy (HBOT) for a severe type of inflammatory bowel disease called perianal Crohn's disease (PCD). PCD causes painful perianal infections and chronic drainage from fistula tracts, and current treatments are only moderately effective and may not be suitable for all patients. HBOT is a safe and commonly used treatment for chronic non-healing wounds and other conditions. Previous studies have suggested that HBOT may help heal fistulas in PCD patients, but these studies were small and lacked controls.

Colorectal Omics and ofCS Proteoglycans (COCO) in Screening and a Diagnostic Pathway

Colorectal Cancer (CRC), or bowel cancer, is a serious disease that affects many people globally. The earlier CRC is diagnosed, the better the patient outcomes. The problem with the current diagnostic methods is that they lead to many unnecessary endoscopies (colonoscopies). In Denmark alone, over 30,000 patients every year undergo a colonoscopy without having a serious disease. This puts a major strain on both patients and the healthcare system. This research project aims to solve that problem. COCO-S is investigating oncofoetal chondroitin sulphate-modified proteoglycans (ofCS) to see if ofCS can be used as a novel, unique cancer marker found in the blood. ofCS are special molecules that reappear in most tumour tissues. A method has been developed to detect ofCSs in a simple blood sample. Initial findings from an ongoing study are highly promising. A test using five different ofCS markers has shown very high accuracy in detecting CRC: it correctly identifies 86% of cancer cases (sensitivity) and correctly gives a "negative" result in 97% of cases without cancer (specificity). The results also suggest that high ofCS levels might help clinicians detect adenomas (polyps), which are early precursors to cancer. Combining the analysis of ofCS in the blood with the existing stool test (FIT) and other promising blood markers can significantly improve patient selection for a colonoscopy. This project will collect blood samples from patients scheduled for a colonoscopy. The blood will be analysed for ofCS and other substances to determine the combined predictive value for patients who truly require the procedure. The findings from this project could revolutionize CRC diagnosis. By more accurately identifying patients who need a colonoscopy, the number of unnecessary, invasive procedures can be reduced while maintaining patient safety and ensuring cancer is found in time.

Fermented Vegan Optimized Diet in Health and Colitis

The diet is assumed to contribute to many of our present non-communicable diseases. Vegetarian products are instead considered to be health promoting, However, it is not verified that the modern vegetarian and vegan products are healthier than the ones they are meant to replace. Products based on vegetables are nowadays often produced with advanced techniques and can therefore differ substantially from the original vegetables. The epithelium in the gut is protected by a mucus layer that efficiently prevents bacteria to encounter the epithelium and even to translocate into the gut and the blood stream. In several inflammatory conditions such as e.g., inflammatory bowel disease (IBD) the barrier integrity is disrupted, and translocation will occur. Fibers are important for the gut microbiota enabling the production of short chain fatty acids (SCFA) that is necessary as nutrition for the epithelial cells, Fibers also promote the development of mucus. The aim of the present study is to evaluate components in the diet that is claimed to be health promoting even though they sometimes can be a hazard to your health. Both fibers and antinutrients can be found in these dietary regimens. The health effects of these products will be studied by analysis of the gut microbiota and the barrier integrity as markers of the health status. Gut microbiota will be analyzed with next generation sequencing and q-PCR (polymerase chain reaction). Diversity and the occurrence of different species will be determined. The barrier integrity will be estimated by analysis of bacterial DNA in blood and presence of live bacteria. The study consists of two different parts: 1a. 60 health volunteers are divided into two groups. One group consumes ordinary dairy based yogurt and the other a yogurt based on vegan products for four weeks to enable a change in the gut microbiota. At start and after four weeks fecal samples and questionnaires about the general health and gastrointestinal symptoms will be retrieved. It should be noted that the compounds offered can be bought in the ordinary shops. 1. b. The same design as above but with IBD patients instead. Their disease activity will be monitored by scoring sheets and regular blood tests as a part of their regular check-up. 2. a. The same design as in 1a but with comparison between a regular meat-based diet and a diet with vegetarian meat substitutes instead. 2b. The same design as I 2a but with IBD patients. Healthy volunteers will be invited wit advertisements. The IBD patients will be recruited at the out-patient clinic at the Dept of Gastroenterology at Skåne university hospital, Sweden. Before inclusion their disease activity will be monitored. The study is a prospective non-randomized intervention study including both men and women. Each individual will serve as their own control. The meals based on meat substitutes will be composed in cooperation with a dietitian. The estimated amount of yogurt is 200-250 gram/day, and the amount of meat is 150-200 gram/day.

Visualization of the Colon Through Use of the Magnetic Flexible Endoscope (MFE) in Participants With Inflammatory Bowel Disease (IBD)

In this study, the investigators will test the ability of the Magnetic Flexible Endoscope (MFE) to travel through the colon of people with Inflammatory Bowel Disease (IBD). The MFE is a device made of ultra-flexible tubing that contains a camera, light, and magnet at the tip. The tip of the tube is about the size of a penny. The magnet inside the tip allows the MFE to be moved through the colon by a second magnet attached to a robotic arm that is outside the body. The purpose of this study is to see how the MFE travels through the colon of IBD patients and if it is tolerable.

Benefit of Moderate Intensity Exercise in Patients With Clinical Quiescent Inflammatory Bowel Disease

The goal of this Randomised controlled trial is to investigate the effect of exercise on changes in quality of life in in patients with clinical quiescent Inflammatory bowel Disease. The main question it aims to answer * The Relationship Between Moderate-Intensity Exercise and Quality of Life in Patients with clinical quiescent nflammatory Bowel Disease Over a Six-Month Period * To examine the association between the recurrence of clinical symptoms(defined as a Harvey-Bradshaw Index \> 5 for Crohn's disease and a Mayo Ulcerative Colitis Subscore \> 2 for Ulcerative Colitis) and changes in inflammatory markers in blood and stool, comparing patients with clinical quiescent inflammatory bowel disease (IBD) who engage in regular exercise versus those who do not. * To evaluate the relationship between higher levels of physical activity and quality of life, sleep quality, and stress levels in patients with clinical quiescent IBD. * To assess changes in body composition including body mass index (BMI), fat mass, total muscle mass, skeletal muscle mass, and skeletal muscle index between patients who exercise regularly and those who do not. Intervened participants will be encoraged in moderate-intensity exercise for at least 30 minutes per session, three times per week or more, under the supervision and guidance of a sports scientist compared participants who do not receive exercise training or supervision from a sports scientist.

This is a Randomized, Double-Blind, Placebo-Controlled, Single and Multiple Ascending Dose Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of QLS1510 in Healthy participants

Mediterranean Diet and Time-Restricted Feeding in Ulcerative Colitis Remission

This study will evaluate whether a 12-week dietary intervention can improve gut health, inflammation, and quality of life in adults with ulcerative colitis in remission. Participants will be randomly assigned to one of three groups: a Mediterranean diet, a Mediterranean diet combined with time-restricted feeding (eating within an 8-hour window each day), or standard dietary advice. The Mediterranean diet emphasizes fruits, vegetables, whole grains, legumes, nuts, olive oil, and fish, while limiting processed foods and red meat. The main outcome will be changes in short-chain fatty acids in stool samples, which are markers of gut health. Additional outcomes include changes in inflammation markers, gastrointestinal symptoms, and quality of life. The results of this study may help identify effective dietary strategies to support patients with ulcerative colitis.

Zymfentra (Infliximab-dyyb) REal World Cohort STudy

The goal of this observational study is to learn about how effective Zymfentra (IFX=dyyb) is when treating patients with Crohn's disease (CD) and ulcerative colitis (UC) Does Zymfentra lead to a reduction in symptoms at intervals throughout one year? Participants being prescribed Zymfentra (IFX-dyyb as part of their regular medical care for CD or UC will answer online survey questions about their bowel habits for 1 year.

Study of DISC-0974-201 in Participants With IBD and Anemia

This is a Phase 2, multicenter, randomized, double-blind placebo-controlled study of DISC-0974 to evaluate safety, tolerability, and efficacy in participants with IBD and anemia of inflammation.

Screening for Disorders of Lipid Metabolism and Familial Hyperlipidemia in Children and Adolescents With Increased Cardiovascular Risk Due to Chronic Diseases Such as Congenital Heart Disease, Chronic Inflammatory Bowel Disease, Celiac Disease and Rheumatic Disorders

Preventive measures are increasingly coming to the forefront of medicine. Many of these measures can be implemented as early as childhood and adolescence. For instance, the early detection and treatment of cardiovascular risk factors can significantly reduce long-term morbidity and mortality associated with cardiovascular diseases such as heart attack and stroke. For years, there has been discussion in Germany about assessing lipid profiles during childhood and adolescence to enable early intervention in cases of conditions like familial hypercholesterolemia. However, comprehensive screening has not yet been established in either clinical guidelines or routine practice. In other countries, such as Norway, universal screening has been conducted for many years and has already demonstrated both its benefits and cost-effectiveness. In Germany, screening, and subsequent early treatment if needed, is currently limited to a small number of children and adolescents-such as patients with type 1 diabetes mellitus (T1DM)-as part of their routine preventive check-ups. The prevalence of dyslipidemia in T1DM is approximately 15%. Reliable prevalence data are lacking for almost all other chronic conditions affecting children and adolescents (e.g., inflammatory bowel disease, celiac disease, rheumatic diseases, congenital heart defects). Through a pilot project at Jena University Hospital, we aim to screen children and adolescents with chronic conditions who are already at increased cardiovascular risk due to their underlying diseases. The project will record lipid levels, clinical data, family history, and lifestyle factors. The results of this study enable us, on the one hand, to help the individual through early diagnosis and consequent treatment recommendations; on the other hand, the data provide important information regarding the prevalence of hyperlipidemia and other risk factors-such as physical inactivity-within this high-risk cohort.

Assessment and Educational Intervention to Reduce Ultra-processed Food Consumption in Pediatric Patients With IBD

This study explores whether simple nutrition education can help children and teens with inflammatory bowel disease (IBD) eat fewer ultra-processed foods (UPFs). UPFs include packaged snacks, sugary drinks, and fast food-items that are high in added sugars, fats, and artificial ingredients. Participants will complete online food recalls to measure what they eat and will then receive either nutrition handouts alone or handouts plus a short educational video about UPFs. Researchers will compare changes in UPF intake between the two groups after several weeks and ask families how useful and acceptable they found the materials. The goal is to identify an effective, practical way to support healthier eating habits and long-term gut health in pediatric IBD.

Biophysical Assessments of Acupuncture Points in Inflammatory Bowel Disease

Acupuncture points or acupoints are fundamental to the practice of acupuncture, yet their scientific basis remains unclear. According to traditional explanations of acupuncture, acupoints can become tender or more sensitive to pressure when there is an underlying disease of the body. Findings from recent basic animal studies support this traditional theory. For example, compared to healthy control animals, models of colitis have shown increased skin temperature, blood flow, and pain sensitivity at specific body regions that correspond to the location of acupoints that are commonly used in acupuncture treatment for colitis. However, little is known about whether these findings apply to humans.

Prospective Evaluation of Flare Detection in IBD With Digital Biomarkers: Bring Your Own Device Study

The aim of this study is to identify HRV changes predictive of IBD flares using patient-own wearable devices in a large cohort supplemented by additional data layers including sleep parameters, step count and clinical data extracted from electronic patient files.

Comparison Diagnostic Tests for the Diagnosis of CYTOmegalovirus Organ Disease in Patients With intestinalBOweL Diseases

Observational, single-center, non-pharmacological, prospective study of adult patients affected by Inflammatory Bowel Disease (IBD) with an ongoing disease exacerbation requiring hospitalization

Enabling Microbiomics- Driven Personalized Nutrition

The goal of this observational research study is to determine how diet contributes to various gastrointestinal related conditions. The main question investigators aim to answer is: Are host genetics, diet, and microbiome all important determinants of GI disorders, and how their relative contribution varies among individuals and populations.

AIM-IBD: A Microbiome-Targeted Supplement in Mild-to-Moderate Ulcerative Colitis

This Phase 2b randomized, double-blind, placebo-controlled, multicenter trial will evaluate the efficacy and safety of a once-daily oral microbiome-targeted food supplement compared with matching placebo in adults with mild-to-moderate, objectively active ulcerative colitis. The supplement is food-grade and is intended for use either alongside stable standard ulcerative colitis therapy (5-aminosalicylic acid/mesalamine) or in participants not currently on any inflammatory bowel disease therapy. Approximately 162 participants will be enrolled at university hospital centers in Turkey and randomized in a 1:1 ratio to receive either the food supplement or matching placebo for 24 weeks, in addition to their existing background therapy as defined by eligibility. The primary objective is to determine whether the supplement increases the proportion of participants achieving composite clinical-plus-biochemical remission at Week 24. This composite endpoint requires absence of rectal bleeding, improvement in stool frequency, fecal calprotectin ≤250 micrograms/g, and no rescue therapy, prohibited treatment escalation, ulcerative colitis-related hospitalization, colectomy, or discontinuation for lack of efficacy before Week 24. Key secondary endpoints include endoscopic improvement, deep biochemical remission, change in fecal calprotectin, change in partial Mayo score, corticosteroid-free composite remission, change in quality of life, change in C-reactive protein, time to treatment failure, and safety. Exploratory analyses will assess stool microbiome composition, eukaryotic carriage including Blastocystis, and associations between baseline microbiome features and treatment response.

Metabolic Reprogramming of Monocytes in Inflammatory Flares of Inflammatory Bowel Diseases

Inflammatory bowel diseases, Crohn's disease and haemorrhagic rectocolitis, are pathologies that progress in flare-ups, impacting on patients' quality of life and functional or even vital prognosis. These inflammatory diseases require the use of immunosuppressive and immunomodulatory treatments, the side-effects of which can be significant, and the limited number of which sometimes puts patients and practitioners in a therapeutic impasse from which surgery is the only way out. It is therefore important to be able to develop new therapeutic approaches, ideally better tolerated, that can control inflammation during relapses. Monocytes are one of the main players in the inflammatory reaction. In the laboratory, we have developed a strategy for the metabolic reprogramming of these cells based on the use of oxygen microbubbles to modulate the inflammatory response of monocytes.

A Trial of Academic Detailing to Promote Prescribing of Biosimilars

The goal of this trial is to learn if an interactive evidence-based educational outreach visits to clinicians who prescribe biologics change prescribing of biosimilar medications. The main questions it aims to answer are: 1. Do educational outreach visits lead to a higher number of prescriptions for biosimilar versions of adalimumab? 2. Do in-person or virtual visits work better? Researchers will compare clinicians offered the educational outreach visit to those who are not offered the visit to see if there is a difference in prescribing of biosimilar versions of adalimumab instead of the original brand-name version. Participants will be offered the chance to meet with a trained clinician who will provide educational information tailored to their knowledge and attitudes on the topic. They will also be provided an educational brochure and patient educational materials.

Evaluating the Shift From Intravenous to Subcutaneous Vedolizumab for Inflammatory Bowel Disease

The goal of this retrospective study is to learn about dosing patterns in patients starting subcutaneous vedolizumab administration and patient outcomes after starting subcutaneous administration. Patients with IBD who are starting subcutaneous vedolizumab administration between September 1, 2023, and March 31, 2025, as part of normal patient care, will be retrospectively reviewed and analyzed.

Clinical Investigation of MYIBDDiet App Developed for Inflammatory Bowel Disease (IBD) Patients to Self-manage Their Diet

The goal of this clinical trial is to learn if an app designed for diet education can help patients with inflammatory bowel disease (IBD) learn about healthy eating. The main question\[s\] it aims to answer are: * Is the app easy to use? * Is the app useful? Researchers will compare the diet app to see if it is better at teaching patients about a healthy diet than the standard information they may receive from their doctor. Participants will be asked to use the app for one month and answer surveys to see how easy the app is to use and if it leads to healthier eating.

A Study in Adults With Ulcerative Colitis (UC) or Crohn's Disease (CD) Receiving Vedolizumab in Real-World Practice in Poland

The primary reason of this study is to observe current treatment options in participants receiving Vedolizumab, intravenous (IV) or subcutaneous (SC), for IBD in Poland. There is no treatment involved in this study, this is only an observational review of ongoing/initiating treatment data relating to Vedolizumab induction and maintenance treatment for IBD \[including Ulcerative Colitis (UC) and Crohn's Disease (CD)\].

A Phase 1 Study of PVT401 in Healthy Subjects

The goal of this clinical trial is to learn what happens to PVT401 when it enters the human body and how it affects the immune system. It will also provide information about the safety of PVT401 after a single dose and after multiple doses. The main questions it aims to answer are: Will participants experience any side effects when taking PVT401? How long does it take PVT401 to leave the body after it is administered? Healthy volunteers will participate in either the single ascending dose (SAD) or multiple ascending dose (MAD) phase. In the SAD phase, participants will: stay in the clinic for two nights, get one dose of PVT401 or a placebo intravenously (through a vein) on Day 1, have blood drawn periodically throughout their stay and be monitored for side effects, and return to the clinic for 3 follow up visits over the four weeks after dosing. In the MAD phase, participants will: stay in the clinic for one night prior to each dose of PVT401 or placebo, and get dosed twice a week for 5 weeks. They will have blood drawn periodically throughout the treatment period and be monitored for side effects, and return to the clinic for 4 follow up visits over the six months after dosing.

Virtual Versus Dye-based Chromoendoscopy in Inflammatory Bowel Disease Surveillance Colonoscopy

People with inflammatory bowel disease (IBD), such as ulcerative colitis or Crohn's disease affecting the colon, have a higher risk of developing colon cancer over time. To catch early signs of cancer, regular colonoscopies are recommended. In this study, the investigators are comparing two advanced methods of examining the colon during these surveillance colonoscopies. One method uses a special dye sprayed inside the colon to highlight abnormal areas (called dye-based chromoendoscopy). The other method uses new technology built into the camera to enhance the view without needing any dye (called virtual chromoendoscopy). Both methods use modern, high-definition equipment. The purpose of this study is to find out if the newer, dye-free method is as good as the traditional dye method at detecting pre-cancerous changes (called dysplasia) in people with IBD. Adults with IBD who are due for a routine surveillance colonoscopy may be invited to take part. Participants will be randomly assigned to one of the two methods. No additional procedures are involved, and only the way the colon is viewed differs. The investigators will also look at how long the procedures take, how many biopsies are needed, any complications, and how patients experience the exam. Participants will be followed over time using national health records to check for long-term outcomes. This research will help doctors better understand which method is most effective and comfortable for patients, and may guide future recommendations for cancer screening in people with IBD.
