Multiple fecal transplants may beat single dose for c. diff in colitis patients
NCT ID NCT06071312
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving several fecal transplants (instead of just one) works better to clear repeat C. diff infections in people with ulcerative colitis. About 64 adults with active colitis and repeat C. diff will receive either one or multiple infusions of healthy donor stool. The goal is to see which approach more effectively eradicates the infection and improves gut health.
