Prophylaxis with Dalbavancin for Children with High-Risk Leukemia

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

Phase 1 Interventional St. Jude Children's Research Hospital · NCT06810583

This study is testing if giving dalbavancin to children with high-risk leukemia can help prevent serious bacterial infections while they are getting chemotherapy.

What this trial studies

This clinical trial evaluates the effectiveness of dalbavancin-based prophylaxis in preventing bacterial bloodstream infections in children and adolescents with acute myeloid leukemia or relapsed lymphoblastic leukemia undergoing myelosuppressive chemotherapy. Participants will receive dalbavancin every 28 days for up to 12 weeks, alongside a fluoroquinolone antibiotic, while their pharmacokinetics, tolerability, and acceptability will be assessed. The primary outcome is the rate of bacterial infections during the first 56 days compared to historical controls. The study aims to provide insights into the safety and efficacy of this prophylactic approach in a vulnerable pediatric population.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 25 years or younger receiving treatment for acute myeloid leukemia or relapsed lymphoblastic leukemia at St. Jude Children's Research Hospital.

Not a fit: Patients with allergies to the study drugs or those with active bacterial infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of bacterial infections in high-risk pediatric leukemia patients undergoing chemotherapy.

How similar studies have performed: While this specific approach is novel, similar prophylactic strategies have shown promise in other studies involving pediatric patients with leukemia.
