Effect of a high-fat and high-calorie food on the pharmacokinetics of a novel, potent GABA analog HSK16149 in healthy subjects.
Pharmacology research & perspectives(2023)
摘要
HSK16149 is a novel, potent gamma-aminobutyric acid (GABA) analog for the treatment of neuropathic pain. The purpose of this study was to assess the effect of a high-fat and high-calorie meal on the pharmacokinetics of HSK16149 in healthy Chinese subjects. An open-label, two-period crossover design was applied in this study. Twenty-six subjects were enrolled and were randomly divided into two groups: a fasted-fed group and a fed-fasted group, with 13 subjects in each group. Subjects took a single oral dose of 45 mg of HSK16149 under fasted or fed conditions on Day 1 and Day 4. A series of blood samples were collected for PK analysis. Safety was evaluated throughout the study by physical examinations, clinical laboratory tests, 12-lead ECGs, vital signs, and adverse events (AEs). The parameters AUC , AUC , and C of HSK16149 were compared to assess the bioequivalence of HSK16149 under fasted and fed conditions. The geometric mean ratios (GMRs) and their 90% confidence intervals (CIs) of AUC and AUC under the fed condition compared with the fasted condition were 95.84% (91.94-99.90%) and 95.79% (91.89-99.84%), respectively, which were all within the bioequivalent interval (80.00-125.00%). The GMR (90% CI) of C under the fed condition compared with the fasted condition was 66.04% (59.45-73.36%), which was not within the bioequivalent range (80.00-125.00%). All adverse events were transient and resolved. This study demonstrated that HSK16149 can be administered with or without food.
