New LC–MS/MS method for simultaneous determination of both clofarabine and cytarabine in human plasma with a good selectivity, accuracy and precision.
Wide calibration ranges: 8–1000 ng/ml for clofarabine and 20–2500 ng/ml for cytarabine.
The simple sample preparation and short time of analysis allowed for a high sample throughput.
Successfully applied to a pharmacokinetic investigation within a hematological trial in adult patients with acute myeloid leukemia.
