About

Double-blinded, randomised controlled trial to evaluate the clinical efficacy of a single dose of oral capsule-administered faecal microbiota transplantation (FMT) for carbapenemase-producing Enterobacteriaceae (CPE) intestinal decolonisation compared with placebo. Primary outcome is the proportion of patients successfully decolonised of CPE intestinal carriage at 12 weeks after FMT treatment compared with placebo.

Enrollment: 108 estimated patients

Sex: All

Ages: 21+ years old

Volunteers: No Healthy Volunteers

• Females of childbearing potential who are sexually active with a non-sterilised male partner must agree to use at least one method of effective contraception for the duration of the trial.
• Colonisation of the gastrointestinal tract with CPE, confirmed by at least one positive rectal swab taken ≤7 days before randomisation (direct PCR testing using Xpert Carba-R, performed by study team independent of the hospital screening protocol).

• Presence of significant immunosuppression, including but not limited to: use of monoclonal antibody, use of prolonged steroids equivalent to prednisolone dose of ≥20mg/day for ≥28 days, solid organ transplantation, bone marrow transplantation, HIV infection with CD4 count of ≤200, bone marrow transplant, ongoing chemotherapy or radiation therapy, and congenital immunodeficiency.
• Oropharyngeal dysphagia, significant oesophageal dysphagia, or other inability to swallow.
• History of surgery altering gastrointestinal anatomy (e.g. colostomy, colectomy).
• Ileus or small bowel obstruction.
• Risk of aspiration.
• History of gastroparesis.
• Severe food allergy (anaphylaxis or anaphylactoid reaction).
