Antimicrobial Revision in Patients With Persistent Febrile Neutropenia: A Prospective, Randomized Trial
Description
Febrile neutropenia is often seen in patients with hematologic malignancies who receive cytotoxic chemotherapy. These patients are usually placed on posaconazole prophylaxis upon starting chemotherapy. If an episode of febrile neutropenia occurs, generally an anti-pseudomonal beta lactam, like cefepime or piperacillin-tazobactam, is initiated. In patients who continue to fever on these agents, the optimal method of antimicrobial revision has yet to be determined.In this prospective, randomized, open-label, single-center trial, the primary objective is to compare the clinical efficacy of two approaches to antimicrobial revision among patients with persistent febrile neutropenia. Neutropenic patients on cefepime or piperacillin-tazobactam who continue to fever for greater than 96 hours will be randomized to receive either meropenem or micafungin dosed according to local guidelines. The primary outcome is a global success rate including a composite of defervescence within 72 hours of mero
Trial Eligibility
Inclusion Criteria: * ≥ 18 years of age * Diagnosis of hematologic malignancy * Receiving chemotherapy as treatment of hematologic malignancy * Neutropenia defined as an absolute neutrophil count (ANC) ≤ 500 cells/mm3 or an ANC ≤ 1000 cells/mm3 with a predicted decline to \< 500 cells/mm3 within 48 hours * Prescribed cefepime or piperacillin-tazobactam as initial treatment for febrile neutropenia * Persistent fever for ≥ 96 hours since initiation of cefepime or piperacillin-tazobactam OR recurrent fever that occurs ≥ 96 hours since initiation of cefepime or piperacillin-tazobactam (fever defined as single temperature of ≥ 38.3°C (101°F) or a temperature of ≥ 38°C (100.4°F) on two consecutive measures separated by at least one hour) * Receipt of posaconazole as neutropenia prophylaxis for at least 3 calendar days Exclusion Criteria: * Clinically or microbiologically confirmed infection at time of enrollment, For example, a positive culture or rapid diagnostic test, positive imaging (X-ray, CT, MRI) or biomarker, such as galactomannan, that is consistent with infection * History of infection with organism known to be resistant to meropenem or micafungin * Documented allergy to carbapenems or echinocandins * Concomitant use of valproic acid * Uncontrolled seizure disorder * Pregnancy * Previous enrollment in this study
