Active clinical trials for "Crohn Disease"

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 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.

Stenosis is one of the most frequent complications in patients with Crohn's disease (CD). In particular, CD patients with intestinal strictures are often faced with short bowel syndrome after repeated or extensive surgical resection. Endoscopic management shows good efficacy and safety in the treatment of strictures in CD patients. The European Crohn's and Colitis Organisation (ECCO) guideline recommended that endoscopic balloon dilatation is suitable to treat short [<5 cm] strictures of the terminal ileum in CD. Recently, Lan et al. reported that endoscopic stricturotomy appeared to be more effective in treating CD patients with anastomotic stricture than endoscopic balloon dilatation. However, there is no prospective clinical studies evaluating the efficacy and safety of endoscopic stricturotomy in the treatment of fibrostenotic Crohn's disease. The trial aims to compare the efficacy and safety of endoscopic stricturotomy with endoscopic balloon dilation in the treatment of small bowel stricture in patients with Crohn's Disease.

This is a multicenter, randomized, double-blind placebo-controlled, parallel group study to evaluate the efficacy and safety of VTX958 in participants with moderately to severely active Crohn's Disease.

The goal of this clinical trial is to test the ATH-063 drug (single and multiple doses) in Healthy Subjects. The clinical trial aims to evaluate the below. Safety of the drug Tolerability of the drug Pharmacokinetics (PK) (how the human body affects the drug) Pharmacodynamics (PD) (how the drug affects the human body) This will be a single center, Phase 1, First-In-Human, Randomized, Double-Blind (neither the subjects nor the experimenters know which subjects are in the test and control groups), Placebo (a look-alike substance that contains no active drug) - Controlled Study.

To evaluate the safety and feasibility of ExoFlo as a treatment for Perianal Fistulizing Crohn's Disease.

The purpose of this study to evaluate the clinical efficacy of guselkumab in fistulizing, perianal Crohn's disease and to assess the overall safety of guselkumab.

The overall goal of the study is to develop data that can convincingly guide clinicians on the use and efficacy of vedolizumab in patients with small bowel CD. There is an unmet need to identify response to vedolizumab in small bowel CD using objective endpoints. Current data suggest that MR enterography may meet this unmet need. There is an additional unmet need to develop predictive models incorporating both clinical and baseline radiological and endoscopic variables with higher discriminatory performance in identifying longer term clinical remission with vedolizumab. Finally, this proposal is strengthened by the exploratory studies which may identify new proteomic biomarkers that correlate with longer term radiological response with vedolizumab reflecting its latency of response. If successful, these serum biomarkers may guide a personalized approach to the treatment of small bowel CD with vedolizumab, allowing early identification of PNR, monitoring disease activity and the pharmacodynamics of vedolizumab.

Background: Crohn s disease (CD) is an inflammatory bowel disease. It causes inflammation of the gut. Symptoms may include diarrhea, abdominal pain, fatigue, weight loss and malnutrition. CD has no cure, but symptoms can sometimes be controlled with medicine. Researchers want to see if it is safe to treat CD with the medicine vorinostat. It is thought that vorinostat may reduce the inflammation process of CD. This may then help to relieve symptoms of CD. Participants who respond to Vorinostat will be invited to an extension phase of treatment with Vorinostat and possibly a maintenance treatment using Ustekinumab. Objectives: To see if vorinostat is safe for people with moderate-to-severe CD. To see if it is safe for people with moderate-to-sever CD to receive maintenance therapy using Ustekinumab after successful treatment of Vorinostat. Eligibility: Adults 18-65 with moderate-to-severe CD that medicine is not controlling. Design: Phase I is screening. It may last 120 days. Participants will have: Physical exam Medical history Tests of blood, urine, and stool samples Heart test Questionnaires Tuberculosis skin test They may have a colonoscopy and lymphapheresis collection. These will be explained in a separate consent. They will keep a diary of symptoms. Phase II is treatment using Vorinostat. It will take 12-13 weeks. Participants will take the study drug by mouth twice daily for 12 weeks. They will get a weekly phone call to talk about how the drug makes them feel. They will have blood taken regularly. Every 4 weeks, they will have a check-up that will repeat some screening tests. Phase III extension treatment of Vorinostat for an additional 6 months for those who respond to vorinostat and it is safe for them to continue treatment. Participants will continue to receive weekly calls to talk about how the drug makes them feel. They will have blood taken regularly. Every 3 months, they will have a check-up that will repeat some screening tests. Phase IV: is maintenance therapy for 2 years with Ustekinumab. Participants will receive a one time loading dose of ustekinumab, and then will receive the approved maintenance dose once every 8 weeks, at which time they will return to the NIH Clinical Center for evaluation. The participant will get a phone call 3 days after each dose and again 2 weeks later to see how the drug makes them feel. After two years of receiving treatment with ustekinumab the participant will have an end of study visit, where some of the screening tests, including a colonoscopy, will be repeated.

This study will examine whether delivery of high dose steroids, directly into the inflamed bowel via its arterial blood supply, will be better for treating uncontrolled flares of inflammatory bowel disease in patients compared to conventional intra-venous or oral administration of this drug. Patients aged 4-25 years of age will be recruited. In this study, we hope to also learn how this directed steroid delivery during an active flare will improve patient symptoms as well as the appearance of inflamed segments of bowel determined by imaging or biopsy (i.e. at the time of endoscopy). Additional data will determine how the blood vessels in the bowel affect, and potentially even drive the mechanisms, of inflammatory bowel disease.

RESEARCH QUESTION Are handsewn (end to end and Kono S side to side) anastomoses superior to side to side stapled anastomosis after ileocolic resection for Crohn's disease with respect to endoscopic recurrence, gastrointestinal function and costs. HYPOTHESIS Stapled side anastomosis advised in ECCO guidelines heal with ulcerations on the staple line causing systematic over scoring of endoscopic recurrence leading to unjustified restarting of expensive drugs reducing QOL and increasing costs. Side to side saccular configuration causes stasis affecting recurrence and dysfunction. DESIGN Randomised superiority study POPULATION Patients with Crohn requiring (re)resection of the (neo)terminal ileum INTERVENTION Kono S and end to end hand sewn anastomosis USUAL CARE Side to side stapled anastomosis OUTCOME Endoscopic recurrence (local and central reading) at 6 months SAMPLE 25% reduction in 2:1 ratio -> 126 + 63 = 189 patients KEYWORDS Crohn, ileocolic resection, recurrence
