Could a sweetener stop deadly infections in transplant kids?
NCT ID NCT05579639
First seen Jun 27, 2026 · Last updated Aug 25, 2026 · Updated 2 times
Summary
This study tests whether a special wipe containing xylitol, a natural sweetener, can reduce dangerous bloodstream infections in children and young adults undergoing stem cell transplants. These infections often start from bacteria in the mouth and can be life-threatening. Participants will be randomly assigned to receive either the xylitol wipe or a placebo wipe twice daily during their hospital stay.
