Study for Beinaglutide Versus Glargine Therapy in Glycemic Variability of Type 2 Diabetes Mellitus

The investigators wonder in clinical hypoglycemic treatment for patients with hyperglycemia, whether to reduce fasting blood glucose or postprandial blood glucose first.

In this study, subjects with type 2 diabetes mellitus in combination with oral medication will be treated with basic insulin to reduce fasting blood glucose, or with beinaglutide to reduce postprandial blood glucose, in order to find out which one of controling blood glucose can be more effective and observe the change of blood fluctuation.
