Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was designed to evaluate safety and tolerability of a range of doses of VE303 in healthy adult volunteers. The study also evaluated pharmacokinetics of intestinal colonization by the VE303 strains and pharmacodynamics of recovery of the gut microbiota after administration of antibiotics followed by a course of VE303.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

VE303 is a rationally-defined bacterial consortium candidate being developed for the prevention of recurrent C. difficile infection. VE303 consists of 8 types of clonal human commensal bacteria strains selected for their ability to provide colonization resistance to C. difficile and manufactured under GMP conditions.

Allocation Method

NON_RANDOMIZED

Intervention Model

SEQUENTIAL

This Phase 1a/1b, first-in-human, open-label, single-center, dose-escalation study will evaluate the safety and microbiota changes induced by ingestion of VE303 following administration of oral vancomycin and VE303 administered without vancomycin pre-treatment in healthy adult subjects. Approximately 48 subjects are anticipated for enrollment, unless intermediate cohorts are required, in which case, up to an additional 18 subjects (for a total of approximately 66 subjects) may be enrolled.
