ABSTRACT
OBJECTIVE:
Lenvatinib is a tyrosine kinase inhibitor that helps prevent angiogenesis. In this study, we investigated the potential influencing factors on lenvatinib pharmacokinetics to provide a reference for clinical application. MATERIALS ANDMETHODS:
All healthy participants received a single dose of 4 mg lenvatinib mesylate capsules with a high-fat meal or fasted conditions. Lenvatinib plasma concentrations were determined via high-performance liquid chromatography-mass spectrometry/mass spectrometry, and the pharmacokinetic parameters were calculated using WinNonlin 8.1 software. A mixed effect model analysis was adopted to explore the influence factor for the pharmacokinetic parameters of lenvatinib.RESULTS:
After a single oral dose of 4 mg lenvatinib mesylate, the pharmacokinetic parameters for the fasted and fed groups were as follows tmax was 2.0 hours and 4.5 hours, Cmax was 53.60 ng/mL and 45.54 ng/mL, AUC0-t was 597.44 h×ng/mL and 561.51 h×ng/mL, CL was 6.82 L/h and 7.26 L/h, and Vd was 82.82 L and 94.04 L, respectively. Compared with those in the fasted group, decreased Cmax and increased tmax were observed in the fed group. The geometric mean ratios of fed/fasted for Cmax, AUC0-t, and AUC0-∞ were 86.9%, 94.0%, and 93.9%, respectively, and the pharmacokinetics of lenvatinib were significantly influenced by food intake. Gender influenced the pharmacokinetics of lenvatinib; females had higher Cmax and AUC0-t levels after 4 mg lenvatinib. Lenvatinib was well tolerated in healthy Chinese subjects.CONCLUSION:
High-fat diet altered the pharmacokinetic profile of lenvatinib, but not sufficient to significantly impact its clinical efficacy. Therefore, lenvatinib is suitable for administration under fasted or fed conditions.
