Effect of Food on the Pharmacokinetics of Quizartinib.
CLINICAL PHARMACOLOGY IN DRUG DEVELOPMENT(2020)
摘要
Quizartinib is an oral, highly potent, and selective type II FMS-like tyrosine kinase 3 inhibitor in development for acute myeloid leukemia. This parallel-group study evaluated potential food effects on quizartinib absorption in healthy subjects who received a single 30-mg dose after overnight fasting (n = 34) or a high-fat, high-calorie meal (n = 30). Blood samples were collected through 504 hours after dosing, and pharmacokinetic parameters calculated were maximum observed concentration (C-max) and area under plasma concentration-time curve from time 0 to last quantifiable concentration (AUC(last)) and from time 0 to infinity (AUC(inf)). Mean quizartinib pharmacokinetic profiles were similar under fasted and fed conditions. The geometric least squares means ratios (%) for fed/fasted and associated 90% confidence intervals (CIs) for C-max, AUC(last), and AUC(inf) were 91.58 (82.15-102.08), 105.39 (90.79-122.35), and 108.39 (91.54-128.34), respectively. The 90%CI for the ratio fell within the 80% to 125% limits for C-max and AUC(last), with 90%CI for AUC(inf) slightly outside the limits (ie, 128%). Food delayed quizartinib time to C-max by 2 hours. All adverse events were either mild or moderate; no discontinuations due to adverse events occurred. Based on these results, quizartinib can be administered without regard to food.
