Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to show that treatment with Glargine will lead to an improvement in beta cell function especially within times of maximal beta cell stress occurring after a meal. For this reason three different standardized test meals (breakfast, lunch, dinner) will be performed and the postprandial secretion of intact proinsulin levels will be measured. These measurements will be performed with patients treated in combination with metformin and insulin glargine versus metformin plus NPH insulin (within the core study) and if significant difference is observed, with a third treatment arm with metformin plus insulin detemir.

Hypothesis is that the area under the curve (AUC) intact proinsulin levels within 2 hours after test meal dinner of metformin plus insulin glargin differs from AUC intact proinsulin levels of metformin plus NPH insulin.
