The Comeback Study

Fecal Microbiota Transplantation in Chronic Fatigue Syndrome - an RCT

Source: ClinicalTrials.gov · Last updated 23 Feb 2024

Brief summary (registry, in English)

This is a single-center stratified (on gender and donor), block randomized, placebo-controlled, parallel group trial with 12-months follow-up of 80 chronic fatigue syndrome/encephalomyelitis (CFS/ME) participants. Participants will be randomized to treatment by preprocessed thawed donor fecal microbiota transplant or preprocessed thawed autologous fecal microbiota transplant. Primary endpoint is the efficacy of FMT at three months by the Fatigue Severity Scale. The investigators will use patient reported outcomes for primary and secondary outcome measures. Previous studies suggest that a dysbiosis of the gut microbiota may be a key feature in CFS/ME. We hypothesize that A: CFS/ME is caused by a dysbiosis in the gut flora causing barrier leakage of bacterial products, a low grade systemic immune activation and disturbances in the host energy metabolism. B: Recovery of a normal gut flora by fecal microbiota transplantation (FMT) alleviates symptoms and may even induce remission of CFS/ME. This project aims to determine if there is a true cause and effect relationship between a dysbiotic gut flora and CFS/ME by testing if treatment of the observed dysbiosis by FMT also can resolve CFS/ME symptoms. In this process, collection of blood, fecal, and urine samples before and after FMT will open the possibility to explore the relationship between the gut flora, immune response, host energy metabolism and CFS/ME using technologies of microbiomics, metabolomics and immunological characterizations for a better understanding of the pathobiology of CFS/ME.
