Brief Summary:

The purpose of this study is to better understand the effectiveness and safety of microbiome therapies (MT) as a treatment for patients with Multidrug Resistant Organism (MDRO) colonization after an infection. Limited data from prior studies suggest that MT may be an effective treatment to reduce intestinal MDRO colonization Although shedding of MDROs from patients to their surrounding environment is a recognized pathway of transmission, the potential effect of MT on the transmission of MDRO to other patients in the hospital environment is unclear. This study will test the safety and efficacy of MT for this use in hospitalized patients. This study will also help design larger studies.

The MT may help reduce MDROs that colonize the gut. By reducing colonization before infections happen, this could help doctors avoid using "last resort" antibiotics that can have serious side effects like kidney damage. The reduction in MDROs after MT was originally identified in patients treated with MT for recurrent Clostridioides difficile (often called "C. diff") diarrhea. It has been shown that a type of MT called fecal microbiota transplant (FMT) can eliminate both C. difficile and other resistant bacteria.

Condition or disease Intervention/treatment Phase
Multi-drug Resistant Organism Drug: Microbiome Therapeutic Drug: Placebo Phase 2

Detailed Description:

Antimicrobial resistance (AR) has been declared by the World Health Organization to be one of the greatest threats to global health. Every year, at least 2 million people are infected with antibiotic-resistant bacteria, and over 23,000 die from such infections.

This study aims to take initial steps to directly address these public health priorities and clinical threats of MDRO by estimating the safety of the IP in reducing patient-level intestinal MDRO colonization as well as the effect of the IP on environmental contamination. FAIR is a phase 2, randomized, placebo-controlled, double-blind, parallel, clinical trial of the IP for the treatment of MDRO colonization.

The hypothesis is that lyophilized human intestinal microbiota will safely and efficaciously reduce MDRO colonization. This is a randomized, controlled, clinical trial with two arms: a placebo arm and an intervention arm. The target population will include 40 adult inpatients with multi-drug resistant organisms (MDRO) colonization after infection. Target MDRO colonization is defined as a positive clinical microbiology bacterial culture and antibiotic susceptibility result that is consistent with one or more of the following: carbapenem-resistant Enterobacteriaceae (CRE), vancomycin-resistant Enterococcus spp (VRE), extended-spectrum β-lactamase (ESBL) producing Enterobacteriaceae, multidrug-resistant (MDR) Acinetobacter and/or MDR Pseudomonas

Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized Controlled Trial to Further Microbiota Therapy for AntIbiotic-Resistant Bacterial Colonization in Inpatients.
Estimated Study Start Date : April 2024
Estimated Primary Completion Date : June 2025
Estimated Study Completion Date : June 2025

Arm Intervention/treatment
Experimental: microbiome therapeutic
The study intervention is manufactured from a healthy screened donor as an investigational product (IP) and delivered via swallowed capsule after room reset of the patient's hospital room.
Drug: Microbiome Therapeutic
Participants will receive a single course of study treatment (IP, Encapsulated Microbiota): Orally delivered, non-frozen, encapsulated investigational intestinal microbiota, consisting of 16 capsules. One dose (8 capsules) is administered daily (QD) for 2 days. The capsules are to be taken orally with water on an empty stomach.
Other Name: Intervention Group

Placebo Comparator: Placebo
The control arm will remain in routine contact precautions per standard of care, take placebo capsules, and have a room reset.
Drug: Placebo
Participants will receive a single course of study treatment (Color-matched placebo capsules containing microcrystalline cellulose (MCC) powder), consisting of 16 capsules. One dose (8 capsules) is administered daily (QD) for 2 days. The capsules are to be taken orally with water on an empty stomach.
Other Name: Control Group

Primary Outcome Measures :
  1. Change in stool MDRO colony-forming unit (CFU) density [ Time Frame: Day 0, day 14 of last cycle, and 28 weeks ]
    MDRO colony-forming unit (CFU) densities from quantitative stool cultures in placebo vs IP-treated participants.

  2. Change in proportion of MDRO colonized participants after last treatment cycle with the investigational product (IP) [ Time Frame: Day 0, day 14 of last cycle, and 28 weeks ]
    Proportion of stool cultures positive for any target MDRO will be compared in IP-treated vs placebo-treated participants.

Secondary Outcome Measures :
  1. Estimate safety of the IP for MDRO colonization after infection [ Time Frame: Day 0, day 7, day 14, day 30, and 28 weeks ]
    The frequency of adverse events from IP efficacy for reducing recurrent MDRO infection will be assessed by the frequency of MDRO infections at 24 weeks

  2. Severity of adverse events caused by administration of the investigational product [ Time Frame: Day 0, day 7, day 14, day 30, and 28 weeks ]
    Severity of adverse events after administration of MT will be graded as mild, moderate or severe, form the time of MT administration up to 24 weeks.

  3. Estimate efficacy of the IP for reducing recurrent MDRO infection [ Time Frame: Day 0, 28 weeks ]
    Efficacy will be measured by the frequency of MDRO infections from Day 0 of the first cycle until 24 weeks

  4. Time to recurrent MDRO infection after IP administration [ Time Frame: Day 0, 28 weeks ]
    Time to recurrent MDRO infection from Day 0 of first cycle censored at last final safety visit, or death.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Be able to (or have an available Legal Authorized Representative who is able to) understand and be willing to sign a written informed consent document.
  • Be at least 18 years old at the time of consent.
  • Be able and willing to comply with all study protocol requirements, including the ability to swallow capsules.
  • Be colonized with a target MDRO (CRE, VRE, ESBL, MDR Acinetobacter, and/or MDR Pseudomonas) as detected by bacterial culture of stool or perianal/rectal swab.
  • Be willing to discontinue antibiotics, probiotics, other microbiota restoration therapies, and proton pump inhibitors (PPIs) at least one day prior to study Day 0 (Day -1) and throughout the study.
  • The effects of the IP on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
  • If the potential participant is male, and the partner is of childbearing potential, the subject agrees to practice at least one effective method of birth control for the duration of the study.

Exclusion Criteria:

  • Be pregnant, breastfeeding, lactating, or planning a pregnancy during the study duration (through 4 weeks after the last dose of investigational product, or IP), if women of childbearing potential (WOCBP).
