This is a study to evaluate the antiglycemic efficacy and safety of roflumilast + alogliptin compared to alogliptin alone and roflumilast alone; it will also include an open-label exenatide treatment arm as a control. The antiglycemic efficacy of the combination will be evaluated through the measurement of postprandial active GLP-1 level, ß cell secretion activity (via the measurement of C-peptide and insulin levels), appetite sensations (as assessed by VAS) and glycemic control as assessed by a continuous glucose monitoring system (CGMS).
The purpose of this study is to assess the effect of roflumilast plus alogliptin on glucagon-like peptide-1 (GLP-1) and glucose levels in patients with type 2 diabetes.
