Primary Outcome Measures:
  • pharmacokinetics [ Time Frame: two weeks per subject ]
    comparison of pharmacokinetics of anidulafungin given once in every two days or once in every three days

Secondary Outcome Measures:
  • adequate exposure [ Time Frame: 2 weeks for each subject; analysis after 3 months after last subject inclusion ]
    To determine whether adequate exposure is attained by patients undergoing an allogeneic haematopoietic stem cell transplant following myeloablative chemotherapy or receiving intensive chemotherapy for AML-MDS when using a q48 hour or a q72 hour dosing regimen

  • safety [ Time Frame: 3 weeks ]
    To determine the safety of anidulafungin in the patient population

Detailed Description:

Alternate dosing strategies of echinocandin drugs might provide a better efficacy in the treatment of fungal infections as compared to the current label dosing strategy. Before conducting a controlled efficacy trial of echinocandins in haematology patients, the pharmacokinetics of these alternate dosing strategies need to be tested before bringing this idea to practice in a large randomised trial.

Therefore we want to conduct a pharmacokinetic study with anidulafungin given every 48 hours or every 72 hours. This research can be performed best in a group of patients at high risk for developing invasive fungal infections.

Recipients of an allogeneic haematopoietic stem cell transplant (HSCT) or patients receiving intensive chemotherapy for acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) are at a relatively high risk of developing invasive fungal infections and are therefore candidates for primary prophylaxis. However, the options are limited to fluconazole which affords no protection against mould infections. Amphotericin B is not considered useful because of its desoxycholate formulation has too many side effects and its lipid formulations are too expensive nor have the broad-spectrum triazoles itraconazole and voriconazole proved their value in this setting. Anidulafungin is the first of a new class of antifungal drugs quite unlike any others attacking specifically the ß 1-3 -D-glucan synthase of the cell wall. It has relatively few side effects and appears safe and effective for treating Aspergillus and Candida infections. Since these two genera account for 90% of fungal infections in HSCT recipients the drug would seem an ideal candidate for prophylaxis.

Importantly, nothing is known about the pharmacokinetics of alternate dosing regimens of anidulafungin in this patient population. Therefore a pharmacokinetic study of a homogenous cohort of patients is necessary to test the assumption, that adequate exposure is obtained with alternate dosing and that it is safe.
