Active clinical trials for "Crohn Disease"

This study will examine the safety and effectiveness of an experimental drug called J695 for treating patients with Crohn's disease-a long-term recurring inflammation of the small and large intestine. This disease is currently treated with steroids, sulfasalazine (Azulfidine), 5-ASA drugs (Pentasa, Asacol), immune suppressants, antibiotics, and an antibody against TNF-alpha. Despite the number and variety of available therapies for Crohn's disease, many patients do not respond adequately to treatment or they develop severe side effects from the medicines. Therefore, new treatments must be developed. J695 is an antibody that is identical to a human antibody but chemically changed so that it can attach to and eliminate an inflammatory chemical made by the body called interleukin-12 (IL-12). Animal studies have shown that eliminating IL-12 with an antibody can prevent inflammation in the gut and can also heal inflammation that has already developed. Patients 18 years of age and older who have had Crohn's disease for at least 4 months may be eligible for this study. Candidates will be screened with a medical history and physical examination, electrocardiogram, chest X-ray, blood and urine tests, stool analysis and possibly a review of medical records. They will complete a Crohn's Disease Activity Index Questionnaire for 7 days. Participants will be randomly assigned to one of two treatment groups, as follows: Group 1 Patients in this group will receive an injection of either J695 or placebo (a solution that does not contain any active medicine) under the skin on day 1 of the study, on day 29, and then weekly for a total of seven injections. After the last injection, patients will be followed for an additional 18 weeks. They will be monitored periodically throughout the study with physical examinations, disease activity index scores, and blood and urine tests. Group 2 Patients in group 2 will receive an injection of J695 or placebo on day 1 of the study and then weekly for a total of six injections. They will be followed for an additional 18 weeks. Patients will be monitored as described above for group 1. Participants may be asked to undergo additional tests as part of a sub-study in this protocol. These include colonoscopies to examine changes in inflammation in the gut and blood tests to analyze changes in the cells and body chemicals that affect the inflammation.

Crohn's disease (CD) is an incurable chronic inflammatory disorder of the gastrointestinal tract. This study will assess how safe and effective upadacitinib is in treating moderately to severely active CD in real world. Speed of onset and durability of effectiveness will be assessed. Upadacitinib is a drug approved for the treatment of CD. All study participants will receive upadacitinib as prescribed by their study doctor in accordance with approved local label. Approximately 1200 participants will be enrolled in approximately 230 sites across the world. Participants will receive upadacitinib as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 3 years. There is expected to be no additional burden for participants in this trial. Study visits may be conducted on-site or virtually as per standard of care.

To evaluate the effects of infusion of a Fish oil-based lipid emulsion on TNF-α production and other relevant immune functions. A soybean oil emulsion, rich in the omega-6 polyunsaturated fatty acid linoleic acid, will serve as control.

The objective of this study was to evaluate the effect of Whey Protein (WP) and Soy Protein (SP) nutritional supplements on nutritional status and disease activity in Crohn's disease patients.

There is growing evidence that Crohn's disease may be caused by replication of bacteria, perhaps particularly E. coli, within macrophages (a specialized sort of white blood cell). Laboratory studies show that a combination of antibiotics that can penetrate macrophages (such as ciprofloxacin and doxycycline) together with the anti-malarial drug hydroxychloroquine (which makes the contents of macrophage vesicles more alkaline and helps them to kill intracellular bacteria) is particularly effective at killing the E. coli within macrophages.

The purpose of this study is to determine whether infliximab can favourably and safely be discontinued in patients with Crohn's disease in sustained complete clinical, biochemical, and endoscopic remission on infliximab. Further to examine the clinical utility of measuring levels/activity of infliximab and activity of anti-infliximab Ab in patients in sustained complete remission, in order to investigate whether pharmacoimmunological data can predict the clinical outcome and rationalize therapeutic management of these patients with respect to continuation or discontinuation of infliximab therapy. Additional, to investigate the optimal time-point, out of three, to measure this activity.

A disturbance in the diversity of gut bacterial composition could be linked to several immune mediated diseases including inflammatory bowel diseases (IBD). IBD can be classified into Crohn's Disease (CD) and Ulcerative Colitis (UC). Both these diseases occur from abnormal immune reaction to resident gut bacteria.The process of fecal microbiota transplantation (FMT) where fecal bacteria from a healthy individual is transferred into a recipient, has recently received attention as an alternative therapy for individuals affected with these life-altering diseases. In this study, the investigators will perform fecal transplantation on the subjects meeting inclusion criteria, to determine the efficacy and safety of this therapy in subjects with IBD (CD and UC) who are not responding to first line therapy, and are in a flare.

Crohn's disease is a chronic and relapsing inflammatory bowel disease. Many data show that the intestinal flora is involved in the disease and it has been show that patients with Crohn's disease exhibit an abnormal fecal flora that might play a role in inflammation. The purpose of this study is to determine the effect of the fecal flora transplantation on Crohn's disease.

This study will evaluate a novel diet for adult crohn's disease patients (The Crohn's Disease Exclusion Diet - CDED). Half of the patients in this study will receive the CDED alone while the other half will receive the CDED and a liquid diet formula, for 24 weeks.

This study will evaluate higher versus standard adalimumab dosing regimens for induction and maintenance therapy in subjects with moderately to severely active Crohn's Disease and evidence of mucosal ulceration.
