Trial Description

Summary

RATIONALE: Caspofungin acetate or fluconazole may help prevent fungal infections caused by chemotherapy. It is not yet known whether fluconazole is more effective than caspofungin acetate in preventing fungal infections in patients with acute myeloid leukemia who are undergoing chemotherapy.

PURPOSE: This randomized phase III clinical trial is studying caspofungin acetate to see how it works compared to fluconazole in preventing invasive fungal infections in patients with acute myeloid leukemia who are undergoing chemotherapy.

Further Study Information

OBJECTIVES:

Primary

  • To determine if prophylaxis with caspofungin administered during periods of neutropenia following chemotherapy for acute myeloid leukemia (AML) is associated with a lower incidence of proven or probable invasive fungal infections (IFI) compared with fluconazole.

Secondary

  • To determine if prophylaxis with caspofungin will result in a lower incidence of proven or probable cases of invasive aspergillosis (IA) compared with fluconazole.
  • To determine if prophylaxis with caspofungin will result in improved survival compared to fluconazole.
  • To determine if prophylaxis with caspofungin will result in less empiric antifungal therapy compared to fluconazole.
  • To determine the sensitivity, specificity, and positive and negative predictive value of biweekly galactomannan (GM) and beta-D glucan testing in diagnosing IFI.
  • To test the association between single nucleotide polymorphisms (SNPs) in genes involved in innate immunity and proven or probable IFI.
  • To develop predictive models of IFI using SNP in genes involved in immunity and clinical covariates.

OUTLINE: This is a multicenter study. Patients are stratified according to disease (de novo acute myeloid leukemia vs all other patients). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive caspofungin acetate IV over 1 hour once daily (QD) beginning within 24-72 hours after the last dose of chemotherapy for each course and continuing until ANC > 100-500/μL, the next chemotherapy course begins, or patient meets any off-protocol criteria.
  • Arm II: Patients receive fluconazole IV over 2 hours or orally (PO) QD beginning within 24-72 hours after the last dose of chemotherapy for each course and continuing until ANC > 100-500/μL, the next chemotherapy course begins, or patient meets any off-protocol criteria.

In both arms, treatment continues in the absence of invasive fungal infections or disease progression.

Blood samples may be collected twice weekly for antifungal antigen assays and at the end of course 1 for single nucleotide polymorphism analysis.

After completion of study treatment, patients are followed up periodically for 2 years.

Eligibility Criteria

  • Patients with the following diagnoses are not eligible:
  • Acute promyelocytic leukemia (APL)
  • Down syndrome

  • ≤ 1.5 mg/dL (males age 13 to < 16 years)
  • ≤ 1.7 mg/dL (males age ≥ 16 years)
  • Total bilirubin ≤ 1.5 x upper limit of normal (ULN) for age AND SGOT (AST) or SGPT (ALT) < 2.5 x ULN
  • Lactating patients must agree not to nurse a child while on this trial
  • Female patients of childbearing age must have a negative pregnancy test
  • Patients must agree to use an effective birth control method
  • Patients with a documented history of IFI within the previous 30 days are not eligible
