pharmacokinetics and safety of intravenous posaconazole (mk-5592) in chinese participants at high risk for invasive fungal infections (mk-5592-120)

Conditions: Fungal Infection

Summary: the purpose of this study is to evaluate the pharmacokinetics and safety of posaconazole intravenous solution in chinese participants at high risk for invasive fungal infections. neutropenic participants undergoing chemotherapy for acute myelogenous leukemia or myelodysplastic syndromes will be enrolled in the study. the primary hypothesis is to evaluate the pharmacokinetic parameters of intravenous (iv) posaconazole (pos) solution in chinese participants at high risk of invasive fungal infections and determine the percentage of chinese participants who reach steady-state concentration averages of pos in blood plasma of 500 ng/ml and higher. two subgroups were evaluated: subgroup 1 from serial pk blood draw sampling and subgroup 2 from sparse limited pk blood draw sampling.
