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.


Clinical Trial 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. ;
