Physiologically-Based Pharmacokinetic Modeling of the PARP Inhibitor Niraparib. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT A physiologically‐based pharmacokinetic (PBPK) model of niraparib and its primary metabolite using a relevant virtual cancer population is reported here. A series of in vitro experiments using liver S9, microsomes, and hepatocytes with various inhibitors and recombinant supersomes demonstrated that niraparib is specifically metabolized by ...
