Effects of a High-fat Meal on the Pharmacokinetics of the VEGFR Inhibitor Fruquintinib: A Randomized Phase I Study in Healthy Subjects.

The objective of the study was to investigate the tolerability and effect of high-fat food on the pharmacokinetic profile of a fruquintinib capsule in healthy Chinese subjects. METHODS: Healthy Chinese male subjects aged between 18 and 45 years were enrolled in the study. The study included 2 phases: a dose-escalation phase and a food effect-assessment phase. In the dose-escalation phase, subjects were administered a single dose of fruquintinib (2, 3, or 4 mg) in the fasted state. In the food effect-assessment phase, subjects were administered a 4-mg fruquintinib capsule in the fasted and fed states, respectively, in 2 cycles. Blood samples for pharmacokinetic analysis were collected at the designated time points. Tolerability was assessed throughout the study by physical examination including vital sign measurements, clinical laboratory tests, 12-lead ECG, clinical assessments, and monitoring for and spontaneous reporting of adverse events. FINDINGS: Twenty-nine eligible male subjects were enrolled in the study, including 9 in the dose-escalation phase and 20 in the food effect-assessment phase. In the food effect-assessment phase, the ratios (90% CI) of the geometric mean AUC0-∞ and Cmax values for fruquintinib in the fed state to those observed in the fasted state were 97.2% (94.0%-100.4%) and 82.9% (76.7%-89.5%), respectively. The mean (SD) Tmax values of fruquintinib were 3.0 (1.0) and 5.6 (4.5) hours in the fasted and fed states, respectively. The mos...
