NCT01703286

Brief Summary

The general aim of the present study is to investigate the impact of 4 weeks treatment with linagliptin (5 mg) on endothelial function in patients with type 2 diabetes mellitus. In the current trial this effect of linagliptin treatment on endothelial function will be compared against both the sulfonylurea glimepiride and against placebo, which has not been tested in a trial before; as also is the case for other DPP-4 inhibitors. Besides placebo, glimepiride was chosen as a comparator, as it is one compound of the second most used oral antidiabetic drug class.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Flow Mediated Vasodilation (FMD) Under Fasted Condition on Day 28

    Endothelial function under fasted condition was measured with flow mediated vasodilation (FMD). The change from baseline was calculated as the value on Day 28 divided by the respective value at baseline.

    baseline and day 28 for each treatment arm

Secondary Outcomes (3)

  • Change From Baseline in Flow Mediated Vasodilation (FMD) 2 h Post Meal on Day 28

    baseline and day 28 for each treatment arm

  • Change From Baseline in 2 Hours Post Meal Endothelial Independent Vasodilation (EIDV) on Day 28

    baseline and day 28 for each treatment arm

  • Number of Patients With Adverse Events

    up to 20 weeks
