Further MT for Antibiotic-Resistant Bacterial Colonization

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.

Conditions

• Intestinal Multi-drug Resistant Organism Colonization

Interventions

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. Each dose will be taken approximately every 24 hours, with a minimum of 12 hours from the previous dose to a maximum of 36 hours. Both doses must be completed within the stated 36 hours ±12 hours. Depending on the time of the first dose, dosing may occur over 3 calendar days. A second cycle will begin, and a second treatment will be given if the participant is still MDRO positive on Day 14 of Cycle 1. If applicable, Cycle 2 will begin within 7 days of Day 14.

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. Each dose will be taken approximately every 24 hours, with a minimum of 12 hours from the previous dose to a maximum of 36 hours. Both doses must be completed within the stated 36 hours ±12 hours. Depending on the time of the first dose, dosing may occur over 3 calendar days. A second cycle will begin, and a second treatment will be given if the participant is still MDRO positive on Day 14 of Cycle 1. If applicable, Cycle 2 will begin within 7 days of Day 14.
