Effectiveness of Fecal Flora Alteration for Eradication of Carbapenemase-producing Enterobacteriaceae Colonization — EFFECT-CPE  

Infection Clinical Trial

Official title: Effectiveness of Fecal Flora Alteration for Eradication of Carbapenemase-producing Enterobacteriaceae Colonization Trial (EFFECT-CPE): a Multisite, Open-label, Randomized Controlled Feasibility Pilot Trial

Status Suspended

Clinical Trial Summary

Carbapenemase-producing Enterobacteriaceae (CPE) are bacteria carried in the gastrointestinal tract that are resistant to carbapenems, antibiotics of last resort. CPE infections result in death in 25-50% of cases. Fecal microbiota transplantation (FMT) is the transfer of stool from a healthy donor to a recipient to alter the composition of gut microbes. Early studies support its use for eliminating CPE carriage but definitive studies are lacking. The investigators propose a feasibility pilot for a multicenter, non-blinded randomized trial comparing the effectiveness of FMT with no intervention (standard of care) in eliminating intestinal carriage of CPE. Forty patients with CPE will be randomly assigned to receive FMT by enema or no intervention. Feasibility will be demonstrated by the ability to recruit and retain 40 patients over 12 months, and to provide FMT made at a central site to at least one off-site hospital. The primary clinical endpoint for the full trial is CPE intestinal carriage 3 months after the intervention. Secondary endpoints include: CPE carriage at 1, 6 and 12 months; time to decolonization of CPE; safety; CPE infections over 12 months; and, intestinal carriage of other antibiotic-resistant organisms. Data on the clinical outcomes will be collected but not analyzed in this feasibility study.

Clinical Trial Description

This is a multisite, open-label randomized controlled internal pilot trial designed to assess the feasibility of a larger trial aimed at determining the effectiveness of fecal microbiota transplantation (FMT) by enema in short and long term intestinal decolonization of carbapenemase-producing Enterobacteriaceae (CPE). Forty (40) asymptomatic adult patients intestinally colonized with CPE will be allocated in a 1:1 ratio to receive a bowel preparation followed by FMT by enema route, versus standard of care (no intervention). FMT will be provided by the University of Toronto Microbiota Therapeutics Outcomes Program (MTOP), using standardized operating procedures for recruiting and screening FMT donors, manufacturing FMT and administering FMT by enema. The feasibility outcomes are: successful randomization of 40 patients within 12 months, retention of >90% (36/40) of patients up to 6 months, and provision of FMT at a non-primary study site in at least one patient. Data on the clinical and exploratory outcomes will be collected but not analyzed in this pilot study. The primary clinical outcome is incidence of intestinal decolonization of CPE at 3 months. Secondary clinical outcomes include: time to decolonization of CPE; incidence of CPE clinical infections up to 12 months post-intervention; incidence of intestinal decolonization of CPE and other antibiotic-resistant organisms (extended spectrum beta-lactamase Enterobacteriaceae - ESBLs and vancomycin-resistant Enterococci - VRE) at 1, 3, 6 and 12 months post-intervention; and, safety profile. As an exploratory outcome, changes in fecal microbiome composition will be examined before and after intervention. This study leverages existing support, research infrastructures and expertise - including the Toronto Invasive Bacterial Diseases Network (TIBDN), Toronto Antimicrobial Resistance Research Network (TARRN), and the University of Toronto Microbiota Therapeutics Outcomes Program (MTOP) - to optimize feasibility regarding patient recruitment and FMT administration. ;
