Xylitol BSI Multisite - Reduction of Bloodstream Infections From Oral Organisms in Pediatric Stem Cell Transplant
A Phase 2 study testing Xylitol in people with Allogeneic Stem Cell Transplantation, run by Children's Hospital Medical Center, Cincinnati at 3 sites in United States.
Trial summary
Bloodstream infections (BSI) caused by bacteria translocating across injured oral mucosa are a significant cause of morbidity and mortality in patients undergoing stem cell transplantation (SCT). Unfortunately, there are currently no known strategies to prevent these BSI in this vulnerable population. Read more about this study

About this study
Official title: Reduction of Bloodstream Infections From Oral Organisms in Pediatric Stem Cell Transplant: a Randomized, Multicenter, Double-blind , Placebo-controlled Study Evaluating Twice Daily Oral Xylitol
Bloodstream infections (BSI) caused by bacteria translocating across injured oral mucosa are a significant cause of morbidity and mortality in patients undergoing stem cell transplantation (SCT). Unfortunately, there are currently no known strategies to prevent these BSI in this vulnerable population. The investigators will conduct a randomized, double-blind, placebo-controlled trial at three institutions to evaluate the effectiveness of twice daily intraoral xylitol-wipe application on reducing BSI in pediatric SCT patients.
Read the detailed description
Patients will be randomized to receive either twice-daily intraoral grape-flavored xylitol-wipe (intervention arm) or grape-flavored saline wipe (control arm) application in addition to the current standard of care (SOC). The purpose of this study is to determine whether xylitol wipes are effective at reducing bloodstream infections (BSIs), dental plaque, mucositis (redness and ulcers in the mouth), or gingivitis in patients who undergo allogeneic stem cell transplant (SCT).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Xylitol in people with Allogeneic Stem Cell Transplantation, run by Children's Hospital Medical Center, Cincinnati at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: At the recommendation of the DSMB, the study was halted following an interim futility analysis, which determined that continued enrollment would not alter the study outcome.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Bacteremia from an oral organism (time frame: 33 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
