5 Clinical Trials for Various Conditions
This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.
The purpose of this study is to determine the amount and timing of when certain Fermentable Oligo-Di-Monosaccharides and Polyols (FODMAPs), specifically fructose, can be safely reintroduced into the diet of Irritable Bowel Syndrome (IBS) patients that have successfully completed a low-FODMAP elimination diet. The FODMAP diet is an effective treatment for IBS; however it is unclear how patients can successfully reintroduce and liberalize fructose into their diet. The low FODMAP diet is thought to reduce IBS symptoms by decreasing water content and gas production in the bowel and also possibly by altering gut bacteria. Although use of the FODMAP elimination diet can initially successfully treat IBS symptoms for up to 50-75% of patients, the reintroduction diet is difficult for patients to complete and maintain for long periods of time because current methods for reintroduction of FODMAPs are imprecise leading to frequent recurrent symptoms. As a result, patients often continue the low FODMAP elimination diet for additional months because they have difficulties knowing how to add back FODMAPs into their diet. There are no studies to date to help guide patients with FODMAP reintroduction.
The purpose of this study is to learn the efficacy and safety of fecal microbiota transplantation (FMT) using stool from a donor with low proteolytic activity and containing the bacteria Alistipes putredinis in patients with irritable bowel syndrome (IBS) and high proteolytic activity. Proteolytic activity is the breakdown of proteins into smaller polypeptides or amino acids.
This study will evaluate the efficacy and safety of vibegron, a beta-3 adrenergic receptor (β3-AR) agonist, in the treatment of pain associated with irritable bowel syndrome (IBS) due to IBS with predominant diarrhea (IBS-D) or mixed episodes of diarrhea and constipation (IBS-M).
