Comparing early and late stopping of antibiotics in children with cancer and febrile neutropenia

Early Versus Late Stopping of Antibiotics in Children With Cancer and High-risk Febrile Neutropenia

Phase 4 Interventional Murdoch Childrens Research Institute · NCT04948463

This study is testing if stopping antibiotics early is just as safe as the usual practice of waiting until children with cancer and fever have fully recovered before stopping their antibiotics.

What this trial studies

This randomized controlled trial aims to evaluate whether stopping empiric antibiotics before the recovery of absolute neutrophil count (ANC) is as safe as the standard practice of stopping antibiotics after ANC recovery in children with cancer experiencing high-risk febrile neutropenia (FN). The study will involve children who have been afebrile and clinically stable for at least 48 hours and will compare outcomes such as fever recurrence and new infections between the two groups. By utilizing a health informatics approach, the trial will integrate patient identification, consent, randomization, and outcome reporting within electronic medical records. The goal is to provide clearer guidance on antibiotic duration to reduce unnecessary exposure and associated risks.

Who should consider this trial

Good fit: Ideal candidates include children diagnosed with acute myeloid leukemia or acute lymphoblastic leukemia undergoing intensive treatment phases, or those within 100 days post hematopoietic stem cell transplantation with febrile neutropenia.

Not a fit: Patients with prolonged febrile neutropenia or documented infections requiring ongoing antibiotic treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to reduced antibiotic exposure and lower risks of side effects and complications in children with cancer.

How similar studies have performed: While there is limited evidence from observational studies and small trials, this approach is novel and aims to clarify conflicting guidelines on antibiotic cessation in febrile neutropenia.
