Drug Interaction Study Between Dorzagliatin and Sitagliptin

A Phase 1, Open-Label, Sequential, Multiple-Dose, Drug-Drug Interaction Study of Dorzagliatin and Sitagliptin in Subjects With Type 2 Diabetes Mellitus

This is a Phase 1, open-label, sequential, multiple-dose, drug interaction study of glucokinase activator dorzagliatin and sitagliptin in subjects with T2DM. Pharmacokinetics and pharmacodynamics when dorzagliatin and sitagliptin given alone and in combination will be studied.
