Early Discontinuation of Antibiotics in Paediatric High-risk Febrile Neutropenia (E-STOP2)
Phase IV, Randomized, Open Label, Parallel Groups Clinical Trial for Evaluating the Early Stop of Antibiotic Treatment in High-risk Febrile Neutropenic Oncohaematological Paediatric Patients (e-STOP 2)
The goal of this clinical trial is to evaluate whether stopping antibiotic treatment early is safe in paediatric patients with cancer who develop high-risk febrile neutropenia but show good clinical evolution and low biomarker levels 48-72 hours after the episode.
The main questions it aims to answer are:
Is early discontinuation of antibiotics as safe as the standard strategy in terms of preventing invasive bacterial infections (such as sepsis, microbiologically documented infection, ICU admission, or death)? Does this strategy reduce the number of days on antibiotics without increasing infection-related complications?
Researchers will compare early antibiotic discontinuation with the standard care strategy to see whether the early-stop approach provides similar safety while reducing antibiotic exposure.
Participants will:
Receive standard initial antibiotic therapy for febrile neutropenia. Undergo clinical and biomarker evaluations (including CRP and PCT).
Be randomly assigned to:
Experimental group: early discontinuation of antibiotics, or Control group: continuation of the standard antibiotic strategy.
Be followed for 28 days after randomisation to monitor safety outcomes and treatment effects.

Detailní popis
Children with cancer who develop febrile neutropenia (FN) routinely receive broad-spectrum intravenous antibiotics to prevent severe bacterial infections. Although this approach is essential in high-risk cases, prolonged antibiotic exposure increases the risk of adverse effects, antimicrobial resistance, drug toxicity, and longer hospital stays. Advances in risk stratification-particularly through clinical stability assessment and biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT)-now allow earlier identification of patients who may no longer require intensive antibiotic coverage.
This study evaluates whether early discontinuation of antibiotic therapy is safe in paediatric patients with cancer who present high-risk FN but show a favourable clinical course 48-72 hours after onset. Eligible patients must meet predefined criteria indicating low risk of invasive bacterial infection (IBI), including clinical stability, absence of microbiologically documented infection, and decreasing biomarker levels. The trial uses a randomised, controlled, open-label design to compare an early-stop strategy with the current standard management.
The rationale for this approach is to determine whether antibiotic therapy can be safely shortened without compromising infection-related outcomes. Limiting unnecessary antibiotic exposure may reduce adverse drug events, improve patient comfort, minimise disruption of the microbiome, and support antimicrobial stewardship programmes. The study also incorporates biomarker measurements (CRP, PCT, IL-8) to explore their predictive value for IBI and to validate an IBI-risk prediction model for this population.
Participants will be monitored closely for signs of bacterial infection or clinical deterioration throughout the 28-day follow-up period. This design enables robust assessment of safety while reflecting real-world clinical decision-making and the potential benefits of personalised antibiotic duration in paediatric oncology care.
