Fecal Microbiota Transplantation for Reducing Gut-Related Side Effects and Improving Treatment Outcomes in Patients with B-Cell Lymphoma Receiving CAR T-cell Therapy

Trial Status: active

This phase II trial evaluates whether fecal microbiota transplantation (FMT) around the time of standard of care chemotherapy and chimeric antigen receptor (CAR) T-cell therapy is effective at reducing gut-related side effects and improving treatment outcomes in patients with B-cell lymphoma who recently received antibiotics. The use of antimicrobials may reduce the number and types of good bacteria in the gut. Research has shown that exposure to broad-spectrum antibiotics prior to CAR T-cell therapy is associated with poor outcomes and toxicities. FMT involves the transplantation of the good, healthy fecal bacteria that would otherwise naturally occur in the body from a healthy individual to a recipient. The fecal matter can be transplanted via colonoscopy or enema or can be put into a capsule to be swallowed. FMT may be safe, tolerable and/or effective in reducing gut-related side effects and improving treatment outcomes in patients with B-cell lymphoma receiving CAR T-cell therapy.
