Randomized, Open-Label, Crossover Studies Evaluating the Effect of Food and Liquid Formulation on the Pharmacokinetics of the Novel Focal Adhesion Kinase (FAK) Inhibitor BI 853520.
Targeted Oncology 2019 Februrary 12
BACKGROUND: BI 853520 is a potent inhibitor of focal adhesion kinase and is currently under clinical development for the treatment of non-hematological malignancies.
OBJECTIVE: The objective of this study was to evaluate the effect of food and liquid dispersion on the pharmacokinetics of BI 853520 in two open-label, crossover substudies.
PATIENTS AND METHODS: Sixteen patients with advanced solid tumors were enrolled in each substudy. The order of administration was randomized, and pharmacokinetic samples were collected for 48 h after administration of a 200 mg dose of BI 853520. Lack of effect would be demonstrated if the 90% confidence interval (CI) of the ratio of the adjusted geometric mean (GMR) of the area under the plasma curve (area under the plasma concentration-time curve from time zero to the last quantifiable concentration at tz [[Formula: see text]] and observed area under the plasma concentration-time curve extrapolated from time zero to infinity [AUC0-∞,obs ]) and maximum plasma concentration (Cmax ) did not cross the 80-125% (bioequivalence) boundaries.
RESULTS: Adjusted GMRs (90% CIs) for the fed versus fasted state were 92.46% (74.24-115.16), 98.17% (78.53-122.74), and 87.34% (71.04-107.38) for [Formula: see text], AUC0-∞,obs , and Cmax , respectively. Although the 90% CIs were not within bioequivalence limits for the food-effect study, the limited reductions in these pharmacokinetic parameters after administration with a high-fat meal are unlikely to be clinically relevant. Compared with a tablet, administration of BI 853520 as a liquid dispersion did not strongly affect [Formula: see text], AUC0-∞,obs , or Cmax , resulting in adjusted GMRs (90% CIs) of 1.00 (0.92-1.09), 0.98 (0.90-1.07), and 0.93 (0.86-1.01), respectively.
CONCLUSIONS: These studies demonstrate that BI 853520 can be given with no food restrictions, and as a liquid dispersion, without strongly impacting pharmacokinetics. These pharmacokinetic properties may help make BI 853520 dosing more convenient and flexible, improving treatment compliance.
