Healthy gut transplant to ease chemo-related thinking and mood problems

Fecal microbial transplantation for chemotherapy behavioral side effects

NIH-funded research Ohio State University · NIH-11260189

This work will try using healthy gut bacteria transferred from donors to help people with cancer who have thinking, mood, or fatigue problems during chemotherapy.

What this research studies

You should know the team first tests the idea in mice to see whether healthy stool can prevent the thinking, mood, and fatigue problems that sometimes follow chemotherapy. They will then run a small pilot trial at Ohio State enrolling breast cancer patients on chemotherapy to check safety and whether the approach is feasible. Participants may receive a donor stool transplant, a transplant using their own stool, or a saline control, given before or during chemotherapy, and researchers will follow thinking, mood, fatigue, inflammation, and gut bacteria over time. Results from the pilot will guide whether larger patient trials are launched.

Who could benefit from this research

Good fit: The pilot trial is aimed at breast cancer patients currently receiving chemotherapy who are willing to travel to the study site and provide clinical and stool samples.

Not a fit: People not receiving chemotherapy, those without chemo-related behavioral symptoms, or patients with medical contraindications to fecal transplants (for example severe immunosuppression or active infections) may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this approach could reduce chemo-related cognitive problems, mood changes, and fatigue and improve quality of life and treatment tolerance.

How similar studies have performed: Preclinical mouse work from this group suggests gut microbes can drive chemo-related behavioral changes, and while FMT is proven for C. difficile, using FMT for chemotherapy-related thinking and mood problems is novel and unproven in patients.
