Can a monthly antibiotic shot keep kids with leukemia safer from infections?
NCT ID NCT06810583
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 2 times
Summary
This early-phase trial is testing whether a long-acting antibiotic called dalbavancin, given once every 28 days along with a short course of oral antibiotics, can prevent serious bloodstream infections in children and young adults with high-risk leukemia. The study will enroll 29 participants receiving chemotherapy that causes prolonged low white blood cell counts. Researchers will measure how many develop infections, how well the drug is tolerated, and how acceptable the treatment schedule is to patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dalbavancin (an antibiotic given by IV every 28 days, plus a fluoroquinolone antibiotic by mouth for the first 28 days)
- What this could lead to
- If it works, this could point toward a new way to prevent dangerous bloodstream infections in children with leukemia during chemotherapy.
- What could go wrong
- This is a very small, early-phase trial with only 29 participants and no comparison group, so results may not apply broadly. The antibiotic combination may also cause side effects or not prevent infections as hoped.

Inclusion Criteria: * Aged less than or equal to 25 years at enrollment * Receiving treatment for AML or relapsed ALL at St. Jude and treatment is expected to cause prolonged (\> 7 days) severe neutropenia (ANC \< 500/ml) * Expected to receive care at St. Jude for at least 56 days following enrollment on the protocol * Female participant, greater than or equal to 9 years old, has a documented negative pregnancy test prior to receipt of study drug. Exclusion Criteria: * Allergy to vancomycin, dalbavancin, teicoplanin, levofloxacin or ciprofloxacin (Not including non-anaphylactic vancomycin infusion reaction) * Documented past or current infection or colonization with pathogenic bacteria resistant to vancomycin plus either ciprofloxacin or levofloxacin, within the prior 6 months * Diagnosed with long QT syndrome * Any condition judged by the investigator to put the participant at high risk from participation * Suspected or proven active bacterial infection * Inability to complete requirements of participation in the study (in the opinion of the investigator) * Expected survival \<28 days * Alkaline phosphatase, alanine transferase or total bilirubin ≥ 3x upper limit of normal for age * Estimated glomerular filtration rate (EGFR) \<30 mL/minute/1.73 m2 * Other absolute contraindication to administration of fluoroquinolone antibiotics or dalbavancin * Participant is pregnant or breastfeeding a child
