The Pharmacokinetics and Pharmacodynamics Study of Single and Multiple Dose of SP2086 in Type 2 Diabetes Patients

Study Overview
=================
Brief Summary
-----------------
SP2086 is a novel inhibitor of Dipeptide base peptidase 4, allows an insulin-independent approach to improve type 2 diabetes hyperglycemia. In this single-dose and multiple-dose study the investigators evaluated the safety, tolerability and PK/PD profiles of SP2086 in Type 2 Diabetes Patients .
