A clinical trial to test whether treating patients with liver cirrhosis with capsules containing healthy stool bacteria or a dummy capsule (placebo) will reduce the time it takes to develop an infection resulting in hospital admission

A PROspective randomised double-blind parallel-group placebo-controlled multicentre trial of faecal MIcrobiota tranSplantation to improve the primary outcomE (first hospitalisation due to infection) in patients with cirrhosis over 24 months (PROMISE)

Active malignancy including hepatocellular carcinoma 11. Patients with an expected life expectancy <6 months or listed for liver transplantation 12. Infected with HIV, hepatitis B or C (patients who have undetectable hepatitis B or C DNA/RNA can be recruited) 13. Patients who have received antibiotics or probiotics (excluding foodstuffs containing ‘live bacteria’ such as live yoghurts, kefir, fermented vegetables such as sauerkraut/kombucha or cheese) within 7 days prior to randomisation 14.

Design outcomes

Primary

MeasureTime frame
Current primary outcome(s) as of 13/02/2026: 1. Time to first infection resulting in presentation to the Emergency Department (ED) or admission into hospital with a confirmed infection 2. Decompensating episodes as defined in the criteria below: a. Resulting in presentation to the Emergency Department b. Resulting in hospital admission When the patients meet the primary endpoint, they do not receive further IMP or attend trial visits, but they will continue to be enrolled in the trial for the purposes of monitoring of other clinical endpoints, e.g. all-cause mortality and liver-related mortality. _____ Previous primary outcome(s): Time to the first infection resulting in hospital admission i.e., the date the patient is admitted to the hospital due to infection, collected using the King's Clinical Trials Unit Index Hospitalisation (Primary Endpoint) form administered by the research nurse at each clinic visit i.e, 3, 6, 9, 12, 15, 18, 21 and 24 months. When the patients meet the primary endpoint, they do not receive further IMP or attend trial visits, but they will continue to be enrolled in the trial for the purposes of monitoring of other clinical endpoints, e.g. all-cause mortality and liver-related mortality.

Secondary

MeasureTime frame
Current key secondary outcome(s) as of 13/02/2026: 1. Time to first infection resulting in hospitalisation over 24 month follow up period (former primary endpoint). 2. Incidence of decompensating events including hepatic encephalopathy, new-onset or worsening ascites or variceal bleeding over 24 month follow up period. 3. Incidence of all-cause infection over 24 month follow up period, including infections not resulting in hospitalisation. 4. Progression to ACLF (the development of one or more extrahepatic organ failures) 5. Infection rates and antibiotic usage following randomisation over 24 month follow up period. 6. Incidence of antimicrobial resistance (AMR) including skin and nose colonisation with methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), extended-spectrum beta-lactamase-producing bacteria (ESBL), fluoroquinolone-resistant Gram-negative and carbapenem-resistant Enterobacteriales (over 24 month follow up period). 7. Hospitalisation rates (liver-related and all-cause), including the length of stay and admission to high dependency/intensive care (over 24 month follow up period). 8. Change in liver disease severity scores at 3-, 6-, 12- and 24-months post randomisation. 9. Change in quality of life (EQ-5D-5L score) at 3, 6, 12 and 24 months post-randomisation 10. All-cause mortality and liver-related mortality 11. Change in depression and anxiety scores using HADS at 3, 6, 12 and 24-months post-randomisation 12. Change in alcohol use disorder-related events in patients enrolled with alcohol-related cirrhosis as assessed by the alcohol-use disorders identification test (AUDIT score) at 3, 6, 12 and 24 months post randomisation, and urinary ethyl glucuronide/ethyl sulphate levels if tested as part of the standard of care. 13. Safety of FMT based on safety assessments including physical examination, clinical laboratory evaluation, vital signs and reported as adverse events (AEs) or serious adverse events (SAEs)
