Clinical Trial Summary

This randomized placebo-controlled double-blind phase II trial tests whether fecal microorganism (microbiota) transplantation prevents severe acute graft versus host disease in adults undergoing allogeneic hematopoietic cell transplantation (HCT). Fecal microbiota transplantation involves receiving processed fecal material orally after allogeneic HCT in order to establish a healthy gut microbiota. Gut microbiota undergoes major alterations during allogeneic HCT because of antibiotic exposures, nutritional changes, and chemotherapy administration. Establishing a healthy gut microbiota via fecal transplantation may help prevent acute graft versus host disease in patients undergoing allogeneic HCT.

Description:

OUTLINE: The first 12 patients are assigned to group I, remaining patients are randomized to 1 of 2 groups.

GROUP I: Patients receive fecal microbiota capsules orally (PO) once daily (QD) for 7 days starting at the time of neutrophil engraftment and discontinuation of anti-bacterial antibiotics.

GROUP II: Patients receive placebo PO QD for 7 days starting at the time of neutrophil engraftment and discontinuation of anti-bacterial antibiotics.

After completion of study intervention, patients are followed up monthly until 12 months post-allogeneic HCT.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Grade III-IV acute graft versus host disease (GVHD)	Based on IBMTR criteria and measured as a probability	Up to 6 months post hematopoietic cell transplantation (HCT)
Secondary	Grade II-IV acute GVHD	Based on IBMTR criteria and measured as a probability	Up to 180 days post HCT
Secondary	Non-relapse mortality	Death not due to relapse/progression of the underlying hematologic disorder and measured as a probability	Up to 180 days post HCT
Secondary	Clostridium difficile diarrhea	Based on a positive stool assay in the consistent clinical setting (e.g. diarrhea) and measured as a probability	Up to 180 days post HCT
Secondary	Chronic GVHD	Diagnosis based on the NIH Consensus Criteria (PMID: 25529383)	At 12 months post-HCT
