NCT07344428
Crohn's disease (CD) is a chronic inflammatory bowel disease with high recurrence and surgical rates. Mucosal healing is a key therapeutic goal, yet current anti-TNF-α biologics achieve only about 30% mucosal healing. Dietary intervention, particularly the Crohn's Disease Exclusion Diet (CDED), shows promise in CD management. Preliminary data suggest that combining CDED with anti-TNF-α biologics may significantly improve mucosal healing rates (42.9% vs 25%). This single-center, prospective, randomized, controlled trial will enroll 185 adult CD patients with active disease (SES-CD ≥3), randomly assigned 1:1 to receive either anti-TNF-α biologics plus CDED or anti-TNF-α biologics alone. The primary endpoint is mucosal healing rate at week 14 (SES-CD=0). Secondary endpoints include clinical remission, endoscopic response, transmural healing, and adverse events. This study aims to provide high-quality evidence for the efficacy and safety of this combined approach in Chinese CD patients.
NCT07352995
The goal of this clinical trial is to use a modified thermal probe to measure temperature rise in the colonic mucosa of participants with inflammatory bowel disease, Crohn's disease, and/or ulcerative colitis. The main question it aims to answer is: Is the thermal probe an effective device to use to detect temperature rise in the colonic mucosa? During the participant's standard of care colonoscopy, the thermal probe will be inserted into the colonoscope. The thermal probe is connected to a temperature transmitter that collects and saves the temperature of the colon in real time.
NCT05627128
The goal of the study is to test the efficacy of a dietary intervention in inducing clinical response and remission for patients with Crohn's disease in a randomized controlled trial. The intervention diet: DAIN has been adapted from the Inflammatory Bowel Disease Anti-Inflammatory Diet or IBD-AID™ taking into account the food availability and preferences of Puerto Ricans. DAIN also includes traditional foods commonly consumed in the typical Puerto Rican diet while maintaining the fundamental components of the IBD-AID™.

NCT05421455
The management of stricturing Crohn's disease (CD) remains challenging. Although surgical resection may be the final way to solve it, the efficacy of biologics for symptomatic CD associated strictures was acceptable. In clinical practice, the chioce of treatment is particularly difficult. Therefore, a clinical trial of biologics versus surgery is needed to assess which one is prefered.
NCT07471438
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that can significantly impair patients' quality of life. Due to its transmural nature (affecting the entire thickness of the intestinal wall), it naturally progresses to intestinal destruction (stenosis, fistula), requiring intestinal resection in approximately half of patients during follow-up. The long-term goal for patients is to maintain a normal life, i.e., without symptoms and without intestinal destruction. To this end, short- and medium-term therapeutic goals have evolved in recent years. Clinical remission is not a sufficient goal, as it has not changed the natural history of the disease. The current goal is to achieve a combination of clinical remission and endoscopic mucosal healing, as this is associated with a reduced risk of adverse outcomes (recurrence of symptoms, hospitalization, intestinal resection). Transmural healing assessed by MRI is also a promising goal associated with a reduced risk of adverse outcomes (recurrence of symptoms, hospitalization, intestinal resection). Furthermore, it is associated with a lower risk of progression to intestinal destruction, unlike endoscopic remission. In this context, transmural healing could soon become the benchmark in terms of therapeutic objectives for Crohn's disease, particularly in the ileum. Although enteric MRI is better accepted than colonoscopy by patients with Crohn's disease, in the ACCEPT1 study, nearly half of patients (48.6%) reported the need to use an intestinal distension product (PEG, mannitol, etc.) as a significant obstacle to repeating entero-MRI, while more than a third complained of vomiting (33.7%) or severe diarrhea (35.0%) induced by these same products. Being able to do without the use of distension products would significantly improve the acceptability of entero-MRI. We hypothesize that an enteric MRI without distension would lead to poorer ileal distension but would allow inflammatory activity scores to be assessed on MRI in a manner similar to an examination with distension, and thus would not impact the need for therapeutic intensification.
NCT05972694
The overall objective of this pilot intervention study is to determine the impact of grape powder (46g/day freeze dried whole grape powder provided by the California Table Grape Commission) on the gut microbiotacomposition in adult patients with the IBD subtype Crohn's disease (CD).
NCT07436910
The primary aim of this study is to assess HRQOL and its associated factors among people with IBD. The target sample will be 385 adult patients diagnosed with IBD (both Crohn's Disease and Ulcerative Colitis). The data will be collected using a self-administered survey.
NCT07433946
This is a multicenter, open-label, randomized two-arm interventional nutritional study evaluating the effects of partial enteral nutrition (LH VIOLA) in patients with Inflammatory Bowel Disease (IBD) at risk of malnutrition. A total of 146 patients (73 per arm) will be enrolled across 4 centers. IBD, including Crohn's Disease and Ulcerative Colitis, is associated with malabsorption, weight loss, sarcopenia, and malnutrition, which negatively impact quality of life and treatment outcomes. Nutritional assessment using the Malnutrition Universal Screening Tool (MUST) will identify patients at risk. Participants will be randomized to receive either nutritional counseling alone or counseling plus oral LH VIOLA supplementation (≥412 kcal/day) for 16 weeks. The primary objective is to evaluate maintenance or recovery of body weight at 16 weeks. Secondary objectives include assessment of weight at 24 weeks, muscle strength (handgrip), body composition and metabolic parameters (BIA/BIVA, vitamin B12/D, pre-albumin), quality of life (SF-12), economic impact, adherence, gastrointestinal tolerability, and reduction in malnutrition risk (MUST score). The study duration per patient is 24 weeks (16 weeks of intervention plus 8 weeks follow-up), with a total study duration of 18 months. The sample size is powered to detect an increase from 40% to 65% in patients achieving weight maintenance or gain at 16 weeks, accounting for a 15% dropout rate.
NCT05316584
The investigators hypothesize that use of a remote monitoring digital health system that supports medication taking and monitoring of symptoms will improve adherence, clinical outcomes, and decrease healthcare utilization compared to standard care in participants with inflammatory bowel disease initiating oral or subcutaneous treatment. The investigators are conducting a 12-month, multicenter, randomized, controlled trial to assess the feasibility and effectiveness of a remote monitoring digital health system on adherence, clinical outcomes, and healthcare utilization. The investigators will address the following specific aims: 1. Compare adherence as measured by the medication possession ratio in participants using a remote monitoring digital health system compared to standard of care. 2. Compare clinical outcomes and healthcare utilization in participants using a remote monitoring digital health system compared to standard of care.
NCT04966585
This trial is designed to evaluate the effects of oral antifungal treatment with posaconazole on active Crohn's disease (CD) activity and the burden of Malassezia spp. in CD patients with the caspase recruitment domain family member 9 (CARD9) S12N risk allele. Further, this project will investigate the hypothesis that the microbial changes induced by antifungal treatment are associated with dampened downstream immune responses in those with a genetic predisposition to developing strong immune responses to Malassezia.
NCT06432764
The purpose of this study is to measure the changes in intestinal uptake of radioligand \[11C\]AZ14132516 following multiple doses of AZD7798 in participants with Crohn's disease.
NCT05197049
The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with Crohn's disease.
NCT07245394
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.
NCT07089420
This study is evaluating the levels of calprotectin, a protein found in stool, in healthy adults. Calprotectin is a marker of inflammation in the intestines and can help doctors tell the difference between inflammatory bowel diseases (IBD), like Crohn's disease or ulcerative colitis, and non-inflammatory conditions like irritable bowel syndrome (IBS). In this study, healthy volunteers aged 22 and older will collect a stool sample at home using a simple kit and mail it to the study site. The samples will be tested using a new laboratory method called the ALPCO Calprotectin CLIA assay. The goal is to confirm what level of calprotectin is considered "normal" in people without intestinal disease. Participation involves just one stool sample, and there are no medical procedures. Volunteers will be compensated for their time. The study will help improve how doctors interpret calprotectin test results in clinical settings.
NCT05698745
The purpose of this study is to evaluate disease progression, in terms of development of symptomatic disease and complications associated with IBD (e.g. fistula, abscess, stricture).
NCT06953791
Crohn's disease (CD), a type of inflammatory bowel disease (IBD), is on the rise globally. Although medical treatments have advanced, CD still leads to significant health issues due to disease progression and medication side effects. Exclusive enteral nutrition (EEN) is a recommended first-line treatment for pediatric CD, proving more effective than oral corticosteroids without side effects. However, EEN demands strict adherence, making it challenging for patients, particularly adults. In 2019, Levine et al. found that a combination of a specific diet (CD exclusion diet, CDED) and partial enteral nutrition (PEN) was as effective as EEN in inducing remission in pediatric patients, with better tolerance and adherence. CDED focuses on whole foods and aims to minimize harmful dietary components affecting the gut. In clinical practice, an adapted CDED (aCDED) has been used to provide more food choices, but it lacks validation in clinical trials. An aCDED that considers regional and seasonal food variations could enhance patient adherence and align with modern dietary preferences. This study aims to compare the quality of life during a flare up of Crohn's disease treated with standard of care or an adapted Crohn's disease exclusion diet with partial enteral nutrition in adult patients.
NCT04263831
The purpose of this study is to determine the safety and maximum effective dose (MED) of Interleukin-2 in subjects with moderate-to-severe crohn's disease.
