Comparison of Repaglinide and Gliclazide in Chinese Subjects With Type 2 Diabetes Never Received Oral Antidiabetic Drug Treatment

A 16-week, Multicentre, Randomised, Open-label, Parallel Group Study to Investigate the Efficacy and Safety Profiles of Repaglinide Monotherapy Compared to Gliclazide Monotherapy in Chinese Antidiabetic-naïve Subjects With Type 2 Diabetes

This trial is conducted in Asia. The aim of this clinical trial is to investigate the blood glucose lowering effect and the safety profile of repaglinide given alone compared to gliclazide given alone in Chinese subjects with type 2 diabetes who never have been treated with oral anti-diabetic drugs (OADs). This study also investigates the augment effect of repaglinide on the phases of insulin secretion as a subgroup study.

• HbA1c: 6.5-8.5%
• Fasting glucose: 6.1-13.0 mmol/L (110-234 mg/dl)
• Body Mass Index (BMI): 20-35 kg/m^2
• Be able and willing to perform self-monitored plasma glucose (SMPG)
