Levofloxacin to Prevent Bacterial Infection in Patients With Acute Myeloid Leukemia Treated by Venetoclax and Azacitidine: A Toulouse-Bordeaux DATAML Registry Study.

Objectives: Antibiotic prophylaxis for patients with cancer remains a controversial issue and is not broadly recommended for hematological malignancies. The venetoclax (VEN) and azacitidine (AZA) combination allows for high rates of complete remission in acute myeloid leukemia (AML) but enhances the incidence of febrile neutropenia (FN) compared to AZA alone, making primary antibiotic prophylaxis a relevant question.

Patients And Methods: Patients with AML who received VEN-AZA were selected from the DATAML registry to investigate the use of levofloxacin (LEVO) prophylaxis, administered at 500 mg/day from day 10 following the first course of VEN-AZA, until neutrophil recovery (>0.
