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.
