Brief summary
This study will evaluate the feasibility of Human Microbiota Transfer Therapy (HMTT) for depression in adults. We will aim to recruit 15 participants to recieve a HMTT enema (n=10) or placebo enema (n=5). We will follow up participants for 8 weeks for primary outcome, measures including recruitment, retention, acceptibility, tolerability, and 6 months for safety data. We hypothesise that HMTT will be a safe and feasible treatment for depression in adults. This pilot data will inform a larger randomised controlled trial evaluating efficacy of HMTT for depression, scheduled to commence in 2022.
Interventions
Faecal Microbiota Transplantation via enema, referred to in this study as Human Microbiota Transfer Therapy (HMTT) Participants will recieve four doses of HMTT via enema over four consecutive days. Each dose will consist of a 50mL volume of faecal suspension, combined with 10% glycerol delivered into the rectum via a syringe. Participants will be required to retain the enema for thirty minutes. The HMTT will be delivered by a study nurse in a hospital environment. Delivery and direct obsersvation by study nurse will ensure adherence to the intervention.
