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.
Type 2 Diabetes
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||A Phase 1b, Randomized, Double-Blind, Active Comparator (Open-Label Exenatide) Controlled Study to Evaluate the Effect of Roflumilast Plus Alogliptin on Postprandial Active GLP-1 Level and 24-hour Glucose Level in Subjects With Type 2 Diabetes Who Are Inadequately Controlled on a Stable Dose of Metformin
Primary Outcome Measures:
Secondary Outcome Measures:
- Changes from baseline in AUC(0-8) of postprandial glucose at Day 11 [ Time Frame: At Baseline and Day 11 blood samples will be collected prior to and up to 8 hours after eating ] [ Designated as safety issue: No ]
The concentration of glucose in blood before and up to 8 hours after eating will be plotted and the area under the curve calculated.
- Change from baseline in AUC(0-8) of C-peptide at Day 11 [ Time Frame: At Baseline and Day 11 blood samples will be collected prior to and up to 8 hours after eating. ] [ Designated as safety issue: No ]
The concentration of C-peptide in blood before and up to 8 hours after eating will be plotted and the area under the curve calculated.
- Change from baseline in AUC(0-8) of insulin at Day 11 [ Time Frame: At Baseline and Day 11 blood samples will be collected prior to and up to 8 hours after eating. ] [ Designated as safety issue: No ]
The concentration of insulin in blood before and up to 8 hours after eating will be plotted and the area under the curve calculated.
- Change from baseline in AUC(0-8) of appetite sensation as measured by visual analog scale (VAS) at Day 11 [ Time Frame: At Baseline and Day 11, every 30 minutes, starting 1 hour before eating until 8 hour after the meal. ] [ Designated as safety issue: No ]
Appetite sensations will be measured using a visual analog scale questionnaire. Participants will be asked to make a point corresponding to their hunger sensation on a 100 mm line with words anchored at each end expressing the most positive or negative sensation.
- Change from Baseline in 24-hour plasma glucose assessed by Continuous Glucose Monitoring System (CGMS) at Day 11 [ Time Frame: Baseline and Day 11 ] [ Designated as safety issue: No ]
Patients will undergo 24-hour continuous glucose monitoring starting in the fasting state in 8 hour prior to the standardized breakfast until16 hours after the breakfast.

Experimental: Roflumilast + alogliptin
Roflumilast dose, orally and Alogliptin dose, orally for 11 days.
Other Name: Daxas, Daliresp
Experimental: Roflumilast dose
Roflumilast dose, orally and alogliptin placebo dose, orally for 11 days
Other Name: Daxas, Daliresp
Alogliptin dose, orally and Roflumilast placebo dose, orally for 11 days
Active Comparator: Exenatide
Exenatide dose for 11 days
Other Name: Byetta
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 CGMS.
