Fecal microbiota transplantation to prevent acute graft-versus-host disease: pre-planned interim analysis of donor effect.

ABSTRACT: Gut microbiota disruptions after allogeneic hematopoietic cell transplantation (alloHCT) are associated with increased risk of acute graft-versus-host disease (aGVHD). We designed a randomized, double-blind placebo-controlled trial to test whether healthy-donor fecal microbiota transplantation (FMT) early after alloHCT reduces the incidence of severe aGVHD. Here, we report the results from the single-arm run-in phase which identified the best of 3 stool donors for the randomized phase. The primary and key secondary endpoints were microbiota engraftment and severe aGVHD, respectively. Three cohorts of patients (20 total) received FMT, each from a different donor. FMT was safe and effective in restoring microbiota diversity and commensal species. Microbiota engraftment, determined from shotg
