Conditions
Keywords
AML, Allo-HCT
Brief summary
This is a randomized, double-blind, placebo-controlled clinical trial of Fecal Microbiota Transplant (FMT) in 2 independent cohorts (60 acute myeloid leukemia patients undergoing intensive chemotherapy and 60 Allo-HCT patients). Participants in each cohort will be randomized in a 2:1 ratio to receive up to 3 treatments of FMT vs. placebo after each exposure to antibacterial antibiotics until 3 months after randomization.
