A Randomized, Double-blind, Placebo-controlled, Multicenter Clinical Trial to Evaluate the Clinical Efficacy and Safety of Yogliptin Tablets

A Randomized, Double-blind, Placebo-controlled, Multicenter Clinical Trial to Evaluate the Clinical Efficacy and Safety of Yogliptin Tablets in Chinese Patients With Type 2 Diabetes Mellitus and Poor Diet and Exercise Control

The purpose of this study is to assess the efficacy of Yogliptin (as monotherapy) compared with placebo after 24 weeks, and the safety (up to 52 weeks) of Yogliptin in Chinese patients with Type 2 diabetes who are insufficient glycaemic control with diet and exercise.

Study Overview

• Status: Recruiting
• Conditions: Type 2 Diabetes
• Intervention / Treatment: Drug: placebo group; Drug: Yogliptin 400mg group; Drug: Yogliptin 200mg group

Detailed Description

The treatment period is composed of a 24-week double-blind period (week 1-24) and a 28-week open-label period (week 25-52). During the double-blind period, participants will receive 200 mg or 400 mg dose of Yogliptin and matching placebo, or placebo only.
