Graft-versus-host Disease Prevention Clinical Trial

This phase II trial studies how well a fecal microbiota transplant with or without total gut decontamination works in preventing graft versus host disease in patients exposed to broad-spectrum antibiotics. Fecal microbiota transplantation is the administration by enema of fecal matter (stool) that includes helpful bacteria from a normal, healthy donor. Total gut decontamination uses antibiotics to remove/reduce the amount of bacteria in the digestive system. It is not yet known if a fecal microbiota transplant with or without total gut decontamination works better in preventing graft versus host disease compared to standard immunosuppressive therapies (therapies that lower the normal function of the immune system).

Inclusion Criteria: - Patients who are day -10 pre- to day +30 post-allogeneic hematopoietic cell transplant (AHCT) from any donor or graft source and for any conditioning regimen - Patients who have received treatment with meropenem or piperacillin-tazobactam (pip-tazo) intravenously (IV) (of at least 24 hours duration) in past 7 days - Controlled infection defined as hemodynamically stable and not requiring supplemental oxygen of more than 2 liters via nasal cannula - Patients who are able to take oral medications in suspension form - Patients who are able to provide informed consent (IC) and comply with all study visits and procedures Exclusion Criteria: - Patients who are anticipated to require continued broad spectrum antibiotics with meropenem or pip-tazo IV for > 96 hours post-engraftment such as for known, documented infections necessitating prolonged treatment - Patients with a prior documented infection with mycormycetes - Patients who are greater than 2 days from time of neutrophil engraftment post AHCT - Patients with active enteric infections - Patients with acute GVHD >= grade II - Patients unwilling or unable to undergo the FMT via retention enema procedure - Patients who have received treatment with an investigational agent within 2 weeks of enrollment - Patients unable to tolerate oral decontamination regimen of pip-tazo and nystatin due to prior allergy or intolerance of these medications - Patients with any medical or psychological condition that, in the opinion of the investigator, might interfere with the subject's participation in the trial, pose any additional risk for the subject, or confound the assessments of the subject |

| Other | Analysis of T-cell subsets | Analysis of T-cell subsets (including specifically regulatory T-cells) will be performed by characterization of peripheral blood flow cytometry. | Up to 6 months post-enrollment | |
| Other | Analysis of serum/stool butyrate levels | Up to 6 months post-enrollment | ||
| Other | Assessment of gut permeability | Will be performed via lactulose/ mannitol assay. | At time of discontinuation of antibiotics (engraftment) | |
| Primary | Development of acute gastrointestinal (GI) graft versus host disease (GVHD) | Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | Within 100 days from time of transplant | |
| Primary | Relapse-free survival | Relapse is defined by either morphological or cytogenetic evidence of acute leukemia or myelodysplastic syndrome (MDS) inconstant with pre-transplant features, or radiologic evidence of lymphoma, documented or not by biopsy. The distribution of time-to-event endpoints, as well as the median and 90% confidence interval, will be estimated using the Kaplan-Meier method. | At 6 months post-randomization | |
| Secondary | Microbiome diversity | Will be measured using the inverse Simpson index. Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | At 2 weeks post fecal microbiota transplantation (FMT) (or engraftment for control arm) | |
| Secondary | Overall maximum stage of lower GI tract GVHD | Will be defined as the proportion of patients who do not develop GI GVHD within 100 days post-transplant and will be monitored simultaneously in cohorts of 5 patients separately in each arm using the approach of Thall, Simon, and Estey. | Within 100 days post-transplant | |
| Secondary | Cumulative incidence of acute GVHD grade II-IV and maximum grade | Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | Up to 6 months | |
| Secondary | Incidence of adverse and serious adverse events | Defined as the proportion of patients who develop blood stream infections caused by enteric bacteria within 60 days of FMT. Will be monitored simultaneously in cohorts of 5 patients separately in each arm using the approach of Thall, Simon, and Estey. | Within 60 days of FMT | |
| Secondary | Incidence of bacterial blood stream infections | Will identify those caused by a potential enteric pathogen. Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | Up to 6 months | |
| Secondary | Hematologic recovery (neutrophils and platelets) | Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | Up to 6 months | |
| Secondary | Characterization of the intestinal microbiota | Summary statistics, including mean, median, range, and standard deviation, will be provided for continuous variables. Frequency tables will be used to summarize categorical variables. | Baseline up to 6 months | |
| Secondary | Non-relapse mortality | Relapse is defined by either morphological or cytogenetic evidence of acute leukemia or MDS inconstant with pre-transplant features, or radiologic evidence of lymphoma, documented or not by biopsy. The distribution of time-to-event endpoints, as well as the median and 90% confidence interval, will be estimated using the Kaplan-Meier method. | At 6 months post-randomization | |
| Secondary | Overall survival | The distribution of time-to-event endpoints, as well as the median and 90% confidence interval, will be estimated using the Kaplan-Meier method. | At 6 months post-randomization |
