DBPR108 is a potent dipeptidylpeptidase-4 inhibitor. This study will be run in four parts to characterize the Drug-Drug Interaction (DDI) potential of DBPR108 with the expected concomitant drugs (Metformin hydrochloride, Glibenclamide, Valsartan, Simvastatin) in Healthy Subjects. Each part of this study consists of a screening period (Day -14 to Day -1), a baseline period (Day -1), a treatment period (Day 1 to Day 9), and a follow-up visit on Day 15. Approximately 14 subjects will be enrolled in each part of this study.
This is a four-part, single-center, open-label, single-sequence crossover phase I clinical study to characterize the Drug-Drug Interaction (DDI) potential of DBPR108 at steady-state with Metformin hydrochloride, Glibenclamide, Valsartan, or Simvastatin in Healthy Subjects. This study also aims to evaluate the safety and tolerability of DBPR108 in the presence of Metformin hydrochloride, Glibenclamide, Valsartan, or Simvastatin.
