| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the study is to investigate the ß-cell function via comparison of the area under the curve over the time period of 0 to 300 minutes (AUC0-300) of intact Proinsulin between T2DM patients treated with LANTUS in combination with MET and T2DM patients treated with SU in combination with MET after uptake of a standardized meal.;Secondary Objective: Comparison of AUC0-300 of intact proinsulin after a standardized meal: - LANTUS + MET patients vs. healthy subjects - LANTUS + MET patients vs. DPP-4 + MET patients - DPP-4 + MET patients vs. healthy subjects - DPP-4 + MET patients vs. SU + MET patients - SU + MET patients vs. healthy subjects Comparison of AUC0-300 for insulin, AUC0-300 and AUC0-180 for glucose (BG) after the standardized meal : - LANTUS + MET patients vs. healthy subjects - LANTUS + MET patients vs. SU + MET patients - LANTUS + MET patients vs. DPP-4 + MET patients - DPP-4 + MET patients vs. healthy subjects - DPP-4 + MET patients vs. SU + MET patients - SU + MET patients vs. healthy subjects Comparison of the mean maximum levels of intact proinsulin, insulin and BG between the 4 groups, comparison of the PAI-1 level excursion at the time points 0, 150 and 300 min between the 4 groups after the meal. Also the change in insulin/ intact proinsulin ratio in between the 4 groups will be analyzed.;Primary end point(s): Comparison of AUC0-300 min [intact Proinsulin] between T2DM patients treated with LANTUS + METFORMIN (MET) and T2DM patients treated with SULFONYLUREA (SU) + MET after uptake of standardized meal | — |
