PHASE2

Fecal Microbiota Transplantation for the Prevention of Acute Graft Versus Host Disease in Adults Undergoing Allogeneic Hematopoietic Cell Transplantation

Sponsor: Fred Hutchinson Cancer Center

View on ClinicalTrials.gov

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.

Prophylactic antiviral and antifungal antibiotics used to prevent infections are allowed Exclusion Criteria: * Severe food allergy in the form of anaphylaxis or attributable symptoms requiring hospitalization * History of chronic aspiration or conditions predisposing to aspiration (e.g. neuromuscular disorders) * Receiving or planned to receive other experimental agents (including ex vivo T-cell depletion) to prevent GVHD. The use of other experimental agents is prohibited unless approved by the principal investigator (PI) of the other trial
