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.

Inclusion criteria

* Age≥ 18 years * Cohort A: Patients undergoing intensive induction chemotherapy for acute myeloid leukemia (AML; newly diagnosed or relapsed/refractory). \* Any intensive regimen with planned \ 4 weeks of inpatient stay * Cohort B: Allo-HCT patients \* Any allogeneic transplant regimen with planned GVHD prophylaxis containing generic IV Mycophenolate Mofetil (MMF) and tacrolimus (Tac) * Sexually active females of childbearing potential and males with partners of child-bearing potential must agree to use adequate birth control until at least six months post-FMT/placebo * Voluntary written consent signed before performance of any study-related procedure not part of normal medical care

Exclusion criteria

* Planned continuation of antibacterial antibiotics after the first neutrophil recovery (ANC \> 1,000) * Patients who are currently receiving or recently received (within 28 days) other investigational agents. * Pregnant or breast feeding. The FDA has not classified this agent into a specified pregnancy category. Females of childbearing potential must have a blood test or urine study within 14 days prior to registration to rule out pregnancy

Time frame: 2 Weeks after first FMT treatment

Population: Only a subset of patients were evaluable for engraftment analysis. This is because they either didn't provide a sample or their sample didn't meet the quality criteria.
