Cytochrome P450 Interaction Clinical Trial
Official title:
A Single-center, Open-Label, Drug Interaction Study to Determine the Effects of Apatinib on the Metabolism of CYP3A4/5 and CYP2C9 Probe Drugs in Patients With Solid Tumors
Apatinib, an oral inhibitor of vascular endothelial growth factor receptor 2（VEGFR-2）, inhibits multiple cytochrome P450 (CYP450) enzymes in vitro. This study in patients with advanced cancer evaluated the effect of Apatinib on CYP450 function by comparing the pharmacokinetics of CYP-specific probe drugs in the presence and absence of Apatinib. The probes used included Nifedipine (CYP3A specific), warfarin (CYP2C9 specific).
This open-label study consists of a drug interaction phase that (part A) and a drug-continuation phase (part B). Patients will receive CYP450-probe drugs, and PK assessments will be performed before apatinib-administration and aſter once-daily administration of apatinib for 5 days (the predicted time point when steady-state plasma apatinib concentrations will have been achieved). ;
