Type 2 Diabetes Mellitus

Brief summary

This study will evaluate how EFB0027 and EFB0026 behave in subjects with type 2 diabetes mellitus. In addition, this study will compare the effects of EFB0027 and EFB0026 on circulating concentrations of glucose and gastrointestinal hormones in subjects with type 2 diabetes mellitus.
