A Prospective Trial of Dalbavancin-Based Prophylaxis in Children and Adolescents With High-Risk Leukemia

Q: Who can participate in NCT06810583?

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.

Q: How do I contact the trial site for NCT06810583?

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.

Q: 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.

A Prospective, Single-Arm, Trial of Dalbavancin-Based Prophylaxis in Children and Adolescents With High-Risk Leukemia

A Prospective Trial of Dalbavancin-Based Prophylaxis in Children and Adolescents With High-Risk Leukemia (NCT06810583) is a Phase 1 interventional studying Leukemia and Acute Myeloid Leukemia, sponsored by St. Jude Children's Research Hospital. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This is a single-arm pilot clinical trial evaluating dalbavancin-based prophylaxis in children and adolescents with acute myeloid leukemia or relapsed lymphoblastic leukemia receiving myelosuppressive chemotherapy. Primary objective: \- To estimate the rate of bacterial bloodstream infection in pediatric patients with AML or relapsed ALL undergoing chemotherapy receiving dalbavancin-based prophylaxis Secondary objectives: * To describe the population pharmacokinetics of every 28 days dalbavancin up to 12 weeks in pediatric patients with AML or relapsed ALL undergoing chemotherapy * To describe the tolerability of every 28 days dalbavancin prophylaxis in pediatric patients with AML or relapsed ALL undergoing chemotherapy * To describe the acceptability of every 28 days dalbavancin prophylaxis in pediatric patients with AML or relapsed ALL undergoing chemotherapy * To estimate the rates of likely bacterial infections, Clostridioides difficile infection, and febrile neutropenia in pediatric patients receiving dalbavancin-based prophylaxis

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Leukemia, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

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.

With a target enrollment of 29 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - 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. Who Should NOT Join This Trial: - 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 - 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 Always talk to your doctor about whether this trial is right for you.
