Type 2 Diabetes Mellitus
Conditions
Brief summary
This is a phase I study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single-dose and multiple-dose of DBPR108 tablets in Type 2 Diabetes Mellitus Patients.
Detailed description
This study aims to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics characteristics, single-dose and multiple-dose of DBPR108 tablets in Chinese Type 2 Diabetes Mellitus Patients. The 30 eligible patients will be randomized to receive 50 mg, 100 mg, or 200 mg DBPR108 tablets.
Interventions
