Hematologic Malignancy Clinical Trial

Official title: Early Neutropenic Fever De-escalation (END) of Antibiotics Study

Status Not yet recruiting

Clinical Trial Summary

This is a randomized, open label clinical trial among individuals with hematologic conditions. The trial aims to evaluate the safety and clinical outcomes of de-escalating antibiotic therapy among stable individuals diagnosed with neutropenic fever, in which no bacterial infection has been identified.

Clinical Trial Description

Background: The Infectious Disease Society of America (IDSA) guidelines for febrile neutropenia conflict with several other international guidelines on duration of antibiotic therapy in patients with febrile neutropenia without a documented infectious source. The IDSA recommends continuing antibiotic therapy until clear signs of marrow recovery, while other guidelines, including the European guidelines, allow for earlier discontinuation if no source of bacterial infection is identified. Benefits of earlier discontinuation of antibiotics include mitigating the risk of induction and amplification of antibiotic resistance, decreased disruption of the microbiome, as well as minimizing potential side effects and complications associated with long-term antibiotic use. To date the only randomized clinical trial in adults evaluating an abridged course of antibiotic therapy in high-risk patients with febrile neutropenia (defined as neutropenia for at least 7 days) was a superiority study that demonstrated fewer days of antibiotic use in the control arm. Safety data were a secondary outcome. Further research is needed to assess the safety and clinical outcomes of targeted antibiotic therapy for patients with febrile neutropenia. Study Design: This is a randomized, open label clinical trial among individuals with hematologic conditions. The trial aims to evaluate the safety and clinical outcomes of de-escalating antibiotic therapy among stable individuals diagnosed with neutropenic fever, in which no bacterial infection has been identified. Treatment Regimen: Intervention Arm (Arm A): Stop antibiotic therapy after episode of fever if afebrile for 48 hours, no clinically documented source of bacterial infection, and no hemodynamic or respiratory decompensation. Control Arm (Arm B): Continue antibiotic therapy per IDSA guidelines until count recovery and/or standard of care as deemed by inpatient providers. Study Participants: The study population will comprise adults who have hematologic high-risk neutropenia (likely > 7 days). ;
