Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A feasibility trial called PROFIT has previously shown that FMT administered endoscopically into the jejunum in patients with cirrhosis is safe and feasible and have identified some potential mechanisms of action that warrant further interrogation. The aim of the PROMISE Trial is to evaluate the efficacy and mechanisms of action of encapsulated FMT (versus placebo) to reduce infection and mortality in patients with alcohol-related and metabolic dysfunction-Associated Steatotic Liver (MASLD) cirrhosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There is an evolving crisis of chronic liver disease (CLD) in the UK and it is the only major chronic disease which is on the rise. The advanced stages of CLD, known as cirrhosis (a hardening and scarring of the liver), is the third biggest cause of death and loss of working life years behind heart disease and self-harm. People die from cirrhosis young with more than 1 in 10 in their 40s.

Patients with cirrhosis are very susceptible to infections, antibiotics become ineffective and patients may become infected with 'super bugs'. There is an urgent need for antibiotic-free approaches. The body contains trillions of microscopic organisms called bacteria which play an important role in keeping us healthy. Many of these bacteria live within our bowel and help our immune system fight infection. There are increased numbers of 'unfriendly' bowel bacteria in patients with cirrhosis which emit substances that are harmful to health and disrupt the immune system.

It could be beneficial to replace the unfriendly bowel bacteria in patients with cirrhosis with bacteria donated from a healthy person by performing a type of bowel bacteria transplant (known as faecal microbiota transplantation or FMT). The PROFIT trial was recently performed as a preliminary trial of FMT which was placed into the bowel with the help of a flexible camera (endoscopy). The study showed FMT was safe with no serious side effects, but patients told us they would prefer to take tablets rather than have an endoscopy. The chief investigator and her team have therefore made a capsule which contains dried stool from a healthy donor. Participants will need to take 5 of these capsules to achieve the same dose.

The PROMISE clinical trial is to test whether treating patients with FMT capsules will reduce the likelihood of them getting an infection by measuring the time it takes to develop an infection resulting in hospital admission. This will be compared to a 'dummy' capsule that contains no FMT (placebo). Patients will be selected at random to have FMT treatment or placebo and both the study team and the patients will not know which treatment they are taking. Participants will need to take 5 capsules every 3-months. Participants will continue treatment for a total of 21-months or until they develop their first infection leading to hospital admission and will be followed-up for a maximum of 2-years.

This study will also examine if having FMT will reduce the side effects of cirrhosis and if it has beneficial effects on the liver and immune system. The investigator team will study whether it reduces hospital admissions, the incidence of 'super-bug' infections and death. Laboratory studies will look at whether FMT treatment will help the immune system fight infection.

The World Health Organisation describes the resistance of bacteria to the effects of antibiotics as one of the biggest threats to global health. The discovery of new antibiotics has not kept pace. The government's white paper proposes a 5-year plan to tackle resistance to antibiotics. Consultation with our patient co-applicant, patient advisory group, The British Liver Trust and Guts UK Charity have highlighted recurrent hospitalisation, over-use of antibiotics and fear of acquiring a 'super-bug' as being important priorities to patients. The results and study findings will be published in conjunction with patient support groups, the wider media and the NHS. The investigator will ensure the research impacts on the management of patients with CLD and shapes policy and guideline development.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients will be randomised 1:1 to FMT or placebo.

Primary Study Purpose

PREVENTION

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors

All participants, Chief Investigator, Site Principal Investigators and outcome assessors will be fully blinded throughout the trial. The site pharmacy trials team and the nurse administering the treatment will be unblinded to a patients treatment allocation.

The senior statistician will also be fully blinded, but the junior statistician will be unblinded from the 1st DMC meeting with data onwards.

Encapsulated Faecal Microbiota Transplant

Intervention Type DRUG

Placebo

The placebo product contains microcrystalline methylcellulose. It is supplied as a size 0, Swedish Orange Delayed-Release capsule (DRCap) and provides a complete match with regards to the appearance (e.g., dimensions, colour) to the FMT capsules.

Intervention Type OTHER
