Fecal Microbiota Transplantation in Patients Undergoing Chimeric Antigen Receptor T-cell Therapy and Allogeneic Stem Cell Transplant: A Pilot Study
Sponsor: University Health Network, Toronto
Summary
This is a single site pilot trial will evaluate the feasibility and safety of fecal microbiota transplantation (FMT) in patients with B-cell lymphoma who are undergoing CAR-T or in patients with moderate to high-risk acute myeloid leukemia or myelodysplastic syndrome who are undergoing allogeneic stem cell transplantation.

Fecal Microbial Transplant Enema
Rectal infusion of FMT will be administered every 48 hours for 2 doses, on 2 separate occasions, detailed in the study calendar. For each series of FMT administrations, the first dose will be 100g and the second will be 50g. Each FMT will be delivered using a single dose (300 ml of prepared fecal filtrate containing 100g or 50g of stool from a donor) delivered using an enema bag and rectal catheter. The procedure, including preparation steps, will take less than 20 - 30 minutes. The second FMT administration will occur in either the inpatient or outpatient setting depending on whether the patient has been discharged from hospital by the time their second FMT series is due at Day +30. The second FMT series will only occur if patients have a neutrophil count of ANC\>1.0 x 109/L without growth factor support for the last 7 days, documented within 7 days prior to the FMT administration.
