Outcomes

Primary Outcome Measures

Number of Participants With Adverse Events as a Measure of Safety and Tolerability
There were 4 mild adverse events observed during the course of study.

Secondary Outcome Measures

Profile of Pharmacokinetics - Area Under the Plasma Concentration-Time Curve (AUC From 0 to Infinity)
Plasma samples were used to determine the AUC from time 0 to infinity for DBPR108. The placebo group is not included in the table below; this outcome measure only evaluated the DBPR108 groups.
Profile of Pharmacokinetics - Observed Maximum Plasma Concentration (Cmax)
Plasma samples were used to determine the Cmax for DBPR108. The placebo group is not included in the table below; this outcome measure only evaluated the DBPR108 groups.
Profile of Pharmacokinetics - Time of Maximum Plasma Concentration (Tmax)
Plasma samples were used to determine the Time of Maximum Plasma Concentration for DBPR108. The placebo group is not included in the table below; this outcome measure only evaluated the DBPR108 groups.
Change of Dipeptidyl Peptidase 4 (DPP4) Activities Between 48 Hrs Post Dose and 0 hr Predose
Change of plasma DPP4 activity at 48 hrs post dose from predose (0 hr). The values were computed as areas under the DPP4 activity-time curve using ANCOVA model, in which the unit of the activity is pmol/min.

5. Study Description

Brief Summary
The study is being performed to assess the safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) properties of single oral doses of DBPR108 in healthy male subjects.
Detailed Description
This study represents the first administration of dipeptidyl peptidase 4 (DPP4) inhibitor DBPR108 to humans to evaluate the safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) properties following single oral doses in healthy subjects. DPP4 is a validated drug target for the treatment of human type 2 diabetes. Objectives of the study will be to characterize the safety and tolerability of single doses of DBPR108; to characterize the single dose PK of DBPR108 in plasma and urine; to characterize the single dose PD of DBPR108 on glucose, glucagon, dipeptidyl peptidase 4 activity, and total and active forms of glucagon-like peptide-1 (GLP-1) in plasma levels and insulin and C-peptide in serum levels.
