Filter by:Fecal Virome Transplantation (FVT) has in small studies shown benefit in the treatment of recurrent C. difficile infection. In the VISION study we will treat patients with recurrent C. difficile infection with FVT capsules and compare the treatment with Fecal Microbiota Transplantation (FMT) capsules. Both will be following af standard treatment of antibiotics (Vancomycin)
A randomized, double-blind, placebo-controlled, pilot clinical study to assess the effect of Doctor's Biome Medical Food (DBMF) in individuals with Clostridium difficile infection (CDI)
Clostridioides difficile infection (CDI) is the leading cause of nosocomial diarrhea in Europe, with over 120,000 cases and almost 3,700 deaths per year. This infection is characterized by a high risk of recurrence after cure, ranging from almost 20% after a first episode to over 60% after 2 recurrences, or in the case of specific risk factors. Currently, first-line treatment of CDI is based on oral antibiotics such as fidaxomicin or vancomycin. These antibiotic treatments, which are effective in 89% and 86% of first-episode cases respectively, do not correct the microbiological imbalance underlying the onset of CDI and may, on the contrary, encourage recurrence by contributing to the maintenance of a deleterious change in the microbiota (dysbiosis) through the elimination of bacteria other than C. difficile, due to their spectrum of activity. In a number of patients, this ecological imbalance can no longer be restored after antibiotic treatment, leading to multiple recurrences of CDI. In this context, fecal microbiota transplantation (FMT) has been validated for over 10 years for the prevention of recurrence in multi-recurrent CDI. The principle of FMT is based on the use of a pharmaceutical preparation made from the stool of a healthy donor, administered within the digestive tract of a patient for therapeutic purposes. Currently, in the case of multiple recurrences, it is the recommended first-line treatment (from 2 recurrences) and the most effective, with a clinical efficacy preventing recurrence of CDI in 69% to 89% of cases at 8 weeks post-treatment, with a good safety profile. Among the microbial factors promoting CDI, the loss of the bacterial species Faecalibacterium prausnitzii constitutes a specific therapeutic target. F. prausnitzii is a commensal bacterium of the human gut, making up nearly 5% of the fecal microbiota, and has been shown to be associated with an individual's state of health. A drop in its relative abundance is associated with an increased risk of numerous diseases, such as Crohn's disease and colorectal cancer. In CDI, F prausnitzii is greatly diminished. Moreover, low abundance of F. prausnitzii is predictive of C. difficile recurrence. Its abundance in stools is increased after FMT and is also predictive of response to treatment. From a pathophysiological point of view, one of the preventive effects of F. prausnitzii on recurrence would be mediated by its ability to hydrolyze the bile acids involved in the germination of C. difficile spores. The aim of this Phase I/II trial is to assess the efficacy and safety of oral administration of EXL01, a single isolated unmodified strain of F. prausnitzii, in preventing CDI recurrence in high-risk patients at W8. The study will be conducted in 2 parts. The phase I (Part A) is planned to include 6 patients. The phase II (Part B) will include 50 patients in two arms (25 patients respectively in the placebo and EXL01 arm).
D8820C00001 is an exploratory, non-interventional, unblinded, observational study evaluating the acceptability, feasibility and performance of methods to collect, transport and test biospecimens in participants ≥ 18 years of age with an active CDI. Participants will also be monitored for recurring episodes of diarrhea and will need to complete validated PROs and study evaluation questionnaires
The overall objective of the RESTORATiVE303 study is to evaluate the safety and the Clostridioides difficile infection (CDI) recurrence rate at Week 8 in participants who receive a 14-day course of VE303 or matching placebo. The objectives and endpoints are identical for Stage 1 (recurrent CDI) and Stage 2 (high-risk primary CDI).
Ulcerative Colitis (UC) is a chronic Inflammatory Bowel Disease characterized by chronic inflammation of the colon. Composition of gut microbiota of UC patients is abnormal (dysbiosis). Ulcerative Colitis patients have an increased risk of Clostridioides difficile infection (CDI) and CDI complications (colectomy, death, recurrence). The reason for this increased risk in IBD patients is not fully understood. The decrease in the proportion of secondary bile acids, induced by microbiota dysbiosis in patients with UC could favor C. difficile infection. The main objective of the study is to describe the composition of bile acids (primary and secondary) in children followed for UC during relapse with or without CDI and to compare it to children with UC in remission and healthy controls. The composition of fecal microbiota will be also describe to correlate dysbiosis and bile acid abnormalities. And finally some fecal biomarkers will be study : short chain fatty acids, metabolic pathway of Tryptophan, and fecal Calprotectin.
The increasing inappropriate use of antimicrobials, in addition to increasing selective pressure and inducing environmental resistance, is also a risk factor for the development of Clostridioides difficile infection (CDI). The intestinal microbiota is mainly composed of the phyla Firmicutes, Bacteroidetes, Acinobacteria, Proteobacteria, Fusobacteria and Verrucomicrobia, and more than 90% of the phylum Firmicutes is composed of Clostridium spp. (two). The inappropriate use of antimicrobials initiates a process of dysregulation of the microbiome, called dysbiosis, and it is from the selection of genera and species of bacteria that will dominate the intestine that pseudomembranous colitis can set in with an increased burden of Clostridioides difficile, a gram positive, anaerobic, spore-forming, that produces two enterotoxins, toxin A and toxin.
This is a randomized, placebo-controlled, dose-ranging study to assess the safety and efficacy of xylitol as an oral therapeutic for decolonization of C. difficile in IBD patients. A total of 99 patients who meet eligibility criteria will be randomized 1:1:1 to one of two xylitol doses or placebo arm. All arms will receive a dose of 10 capsules BID for four weeks. Microbiome assessment and C. difficile testing will be performed at baseline, week 4, 8, 26, and 52.
The purpose of this study is to determine whether a single strain capsulated probiotic, when used after standard C. difficile antibiotic therapy, is effective in reducing the risk of infection recurrence mediated by a decrease in colonization by toxigenic C. difficile. This study will include adults with a history of two episodes of C. difficile infection (CDI).
This is a multisite study to evaluate the safety, tolerability, and efficacy of LMN-201 in participants recently diagnosed with CDI who are scheduled to receive or are receiving SOC antibiotic therapy against C. difficile.
