Xylitol BSI Multisite - Reduction of Bloodstream Infections From Oral Organisms in Pediatric Stem Cell Transplant

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

Xylitol BSI Multisite - Reduction of Bloodstream Infections From Oral Organisms in Pediatric Stem Cell Transplant (NCT05579639) is a Phase 2 interventional studying Allogeneic Stem Cell Transplantation, sponsored by Children's Hospital Medical Center, Cincinnati. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

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.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Allogeneic Stem Cell Transplantation and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 419 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Who May Be Eligible (Plain English)

Who May Qualify: - Provide signed and dated willing to sign a consent form and assent (when applicable) form - Willing to comply with all study procedures and be available for the duration of the study - Admitted and planning to undergo an allogeneic stem cell transplant (SCT) at Cincinnati Children's Hospital Medical Center (CCHMC), Boston Children's Hospital, or Children's Hospital of Colorado (Denver). - Male or female, 4 months to 25 years of age at the time of SCT (Day 0) - Have a minimum of one tooth - Agree to avoid chewing gum and toothpaste that contains xylitol during the intervention period Who Should NOT Join This Trial: - Prior radiation treatment for cancer of the oral cavity, head, or neck in the past 6 months per the study participant's medical record - Cranial boost in patients receiving total body irradiation - Known history of allergy to xylitol - Known history of allergy to grapes or grape flavoring - Undergoing a conditioning-free allogeneic stem cell transplant (patient does not receive any chemotherapy or radiation prior to stem cell infusion) Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT05579639), the sponsor (Children's Hospital Medical Center, Cincinnati), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT05579639?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT05579639?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
