Background

AP23573 is a novel non-prodrug rapamycin analog that potently inhibits mTOR (through bivalent binding to FKBP and mTOR), a downstream effector of PI3K/Akt and nutrient-sensing pathways. A PK model was developed to characterize the blood concentration-time profile of AP23573 and evaluate patient covariate effects following different dosing schedules.
