Filter by:This study evaluates the use of exhaled air analysis as tool to monitor the disease activity in Crohn's Disease (CD). This study is a validation of the previous findings. In this study the participant will be asked to donate exhaled air, blood samples and fecal samples. The breath samples will be used to measure various volatile metabolites in breath. The breath air will be next used to validate the previous findings. The blood samples will be used to define the origin of volatile metabolites in breath. Finally, the potential of exhaled breath analysis as non-invasive marker of diseases activity will be compared to established fecal calprotectin.
Intralesional Tolerogenic Dendritic Cells in Crohn's Disease Treatment.
The primary objective of this trial is to assess whether a 12-week treatment with Ciprofloxacin and Rifaximin is superior to placebo to obtain endoscopic remission in adherent-invasive E. coli (AIEC)-colonized patients with ileal Crohn disease (CD), with or without involvement of the caecum or the right colon.
The purpose of study is to test the effects of an experimental medication GED-0301 (mongersen) in patients who have active Crohn's disease. The study will test GED-0301 compared to placebo for 52 weeks. The study treatment is blinded which means that patients and the study doctor will not know which treatment has been assigned. Patients in this study will be allowed treatment with stable doses of oral aminosalicylates, oral corticosteroids, immunosupressants and antibiotics for the treatment of Crohn's disease. After 12 weeks in the study until the end of the study, patients who do not have an improvement in their Crohns disease symptoms will have the option to enter a long term active treatment study. Participants who discontinued the study anytime or completed the study at Week 52 were then observed for an additional 4 weeks.
A Phase 2b study to evaluate the efficacy and safety of brazikumab (MEDI2070) in participants with moderate to severe Crohn's disease who have failed or are intolerant to anti-tumor necrosis factor-alpha (anti-TNFα) therapy.
Recently, Confocal Laser Endomicroscopy (CLE) has been developed as a novel technique that actually enables in vivo microscopic analysis of the gastrointestinal tract, during ongoing endoscopy. The potential role of CLE has been explored in pathology of both upper and lower gastrointestinal tract, showing good accuracy for predicting the final histopathological diagnosis, based on immediate evaluation of tissue and vascular patterns. Because of its minute scanning area, this techology is best used in conjunction with other "red-flag" techniques to screen the mucosa for areas of interest, which can then be examined by CLE for a histological diagnosis. I-scan technology (Pentax, Tokyo, Japan) is a new image-enhanced endoscopic technique that can achieve a virtual chromoendoscopy, but until now there have been no studies to determine the role of this technology in the evaluation of activity in inflammatory bowel disease. The study protocol is based on comparing imaging findings of p-CLE in conjunction with I-scan endoscopy with activity score and histological diagnosis of inflammatory bowel disease. CLE might have an important role in IBD patients management, by assessing the inflammation, dysplasia or response to treatment.
The objective of this trial is to assess if Fecal Microbiota Therapy (FMT) can reduce the risk of endoscopic recurrence of Crohn's disease (CD) in patients after intestinal resection. The specific outcomes of FMT to be examined are: 1) endoscopic appearance, 2) clinical symptoms, 3) safety and tolerability, and 4) microbial diversity. The research team hypothesizes that FMT will prevent establishment of "pro-inflammatory" microbiome after surgery, leading to a reduced probability of recurrence of macroscopic inflammation. It is also hypothesized that FMT will be safe and well-tolerated in these patients.
The immunogenicity of anti-tumor necrosis factor alpha (anti-TNF) therapy in inflammatory bowel disease (IBD) is an important cause of loss of response to therapy that may lead to escalation of dose or discontinuation of therapy. Antibodies may develop to infliximab (ATI) or to adalimumab (ATA) and cause this loss of response, also known as a secondary loss of response. An alternative approach is the addition of immunomodulator (IM) therapy to counteract the antibody response and regain efficacy of the biologic medication. The investigators' goal is to treat patients' who have lost response to adalimumab or infliximab with an immunomodulator with the goal of eliminating the circulating antibodies to the anti-TNF and restoring efficacy.
This study will primarily evaluate the safety and efficacy of andecaliximab in adults with active Crohn's disease. The study will consist of a Double-Blind Phase of 8 weeks followed by an Open-Label Extension. Participants who complete the Double-Blind Phase will be eligible to enroll in the optional Open-Label Extension for an additional 44 weeks. Participants who complete Week 52 assessments will be eligible to enter the Extended Treatment Phase to continue treatment with andecaliximab for an additional 156 weeks.
This open-label extension and safety monitoring study is composed of two parts: Part 1 will evaluate the long-term safety and efficacy of continued etrolizumab treatment in participants with moderately to severely active Crohn's disease who were previously enrolled in the etrolizumab Phase III Study GA29144 (NCT02394028) and who meet eligibility criteria for enrollment into Part 1. In Part 2, participants who have stopped etrolizumab treatment (either by exiting Part 1 of this study or by entering directly from Study GA29144 [NCT02394028]) will be monitored for 92 weeks for progressive multifocal leukoencephalopathy (PML) and other safety events.
