A Phase III Open-Label Trial of Caspofungin vs. Azole Prophylaxis for Patients at High-Risk for Invasive Fungal Infections (IFI) Following Allogeneic Hematopoietic Cell Transplantation (HCT)
OBJECTIVES:
Primary
- To determine if caspofungin acetate (caspofungin) is associated with a lower incidence
of proven/probable invasive fungal infections (IFI) during the first 42 days following
allogeneic hematopoietic cell transplantation (HCT) at high-risk for IFI compared with
azole (fluconazole or voriconazole) prophylaxis.
Secondary
- To determine if caspofungin is associated with a lower incidence of proven/probable IFI
during the first 100 days following high-risk allogeneic HCT compared with azole
(fluconazole or voriconazole) prophylaxis. (Exploratory)
- To determine if caspofungin is associated with a lower incidence of proven/probable IFI
during the first 42 and 100 days following high-risk allogeneic HCT compared with
fluconazole prophylaxis. (Exploratory)
- To determine if caspofungin is associated with a lower incidence of proven/probable IFI
during the first 42 and 100 days following high-risk allogeneic HCT compared with
voriconazole prophylaxis. (Exploratory)
- To determine if caspofungin is associated with a superior fungal-free survival (FFS)
(time to death or proven/probable IFI) at 42 and 100 days following high-risk
allogeneic HCT compared with azole prophylaxis. (Exploratory)
- To describe the effect that caspofungin and azoles have on the incidence and severity
of acute graft-versus-host disease (GVHD). (Exploratory)
- To determine the diagnostic performance characteristics of galactomannan and beta-D
glucan testing in the setting of different anti-fungal prophylactic strategies for the
early diagnoses of IFI following high-risk allogeneic HCT. (Exploratory)
- To create a DNA specimen bank in anticipation of the development of biology correlative
studies exploring the relationship between IFI and single nucleotide polymorphisms
(SNPs) of genes involved in immunity. (Exploratory)
OUTLINE: This is a multicenter study. Patients are stratified by center's choice of azole
(fluconazole vs voriconazole), age (≥ 12 years vs < 12 years), and type of transplant
(umbilical cord blood [UCB] donor vs non-UCB donor with ex vivo T-cell depletion vs non-UCB
donor with standard pharmacological graft-versus-host disease prophylaxis). Patients are
randomized to 1 of 2 treatment arms.
- Arm I: Patients receive caspofungin acetate IV over 1 hour once daily (QD) beginning
within 24 hours of allogeneic hematopoietic stem cell transplantation (HSCT) and
continuing until day 42 in the absence of invasive fungal infections or disease
progression.
- Arm II: Patients receive fluconazole IV over 1-2 hours QD or orally (PO) QD; or
voriconazole IV over 1-2 hours QD or PO twice daily (BID) beginning within 24 hours of
allogeneic HSCT and continuing until day 42 in the absence of invasive fungal
infections or disease progression.
After completion of study treatment, patients are followed up until days 100-114.
Interventional
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Supportive Care
Development of proven or probable IFI defined according to criteria developed by the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG)
Kaplan-Meier curves will be used to estimate the time to onset of proven/probable IFI for patients randomized to the 2 arms. Log rank test will be used to compare the incidence of IFI between the 2 randomized arms during the at-risk period.
Up to 42 days following stem cell infusion
