Voriconazole in Hematopoietic Stem Cell Transplantation and Cellular Therapies: Real-World Usage and Therapeutic Level Attainment at a Major Transplantation Center

Abstract

Voriconazole (VCZ) was one of the first mold-active triazoles available; however, its current use among high-risk hematology populations is unknown as the uptake of posaconazole (PCZ) and isavuconazole (ISZ) increases. We evaluated the usage and therapeutic level attainment of VCZ in hematopoietic cell transplantation (HCT) and chimeric antigen receptor T cell (CAR-T) therapy patients at our cancer center. Electronic medical records for all adult HCT or CAR-T patients with an order for VCZ, PCZ, or ISV between January 1, 2018, and June 30, 2020, were extracted. Clinical characteristics, VCZ indication, trough VCZ levels, and frequency of VCZ initiation from 6 months before to 6 months after ..
