While the pathophysiology of diarrhea-predominant irritable bowel syndrome (IBS-D) is complex and heterogeneous, dysbiosis of the gut microbiome is frequently observed, suggesting that a substantial subset of patients with irritable bowel syndrome (IBS) have symptoms that are initiated and/or perpetuated by a microbiome dysfunction. Successful randomized controlled trials (RCT) for IBS-D (Ford 2018; Black 2022) leveraging microbiome-targeted therapies (antibiotics or low microbiome fermentation diets) suggest the gut microbiome is at least partially involved in IBS symptoms. Furthermore, fecal microbiota transplantation (FMT) for patients with IBS-D has demonstrated promising results (El-Salhy 2020), supporting the possibility that altering the microbiome composition could ameliorate IBS-D symptoms. MITI-001 is a transplantable gut bacterial community composed of 157 live bacterial strains, encompassing 79 genera of commensal bacteria, that have been isolated from healthy donor stool, purified, and banked. The hypothesis of the proposed research is that MITI-001 can target the pathophysiologic lesion in a subset of IBS-D patients, restore the altered microbial metabolic process, and thus alleviate IBS-D symptoms.

A Randomized, Double-Blind, Placebo-Controlled Direct-to-Consumer Study Assessing the Impact of Health and Wellness Products on Gastrointestinal (GI) Health and Related Health Outcomes

Phase 1 trial to evaluate the Safety and Immunogenicity of Inventprise's (IVT) Shigella-04 in Healthy Young Adults

The purpose of this study is to find out whether SER-155 may be a safe first treatment that causes few or mild side effects for people due to irEC.

The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Autism-spectrum disorder with Gastrointestinal disorders (constipation, diarrhea, and/or abdominal pain). MTT involves a combination of 14 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using Miralax, followed by 5 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.

This is a double-blind, crossover food challenge study using pork with and without α-gal in patients with a clinical diagnosis of gastrointestinal (GI)- α-gal allergy, and to investigate the pathophysiology underlying their symptoms.

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.

The study team's principal interest is to address the question, "Will prophylactic treatment with mesalamine reduce the incidence and severity of immune-related diarrhea occurring secondarily to treatment with ipi/nivo?"
