Purpose
The planned HERMES study is to investigate and compare the effects of Insulin Glulisine, Insulin Aspart and regular human insulin on postprandial nitrotyrosine concentrations and several clinical and laboratory markers of postprandial endothelial cell function, sub-clinical inflammation and cardiovascular risk in patients with type 2 DM. The primary parameter in this study are the postprandial changes in the nitrotyrosine concentrations, a biomarker for oxidative stress. As vascular data on Insulin Glulisine vs. Insulin Aspart are missing, it is not possible to calculate sample size and statistical power. Therefore the goal of the HERMES-Pilot-Study is to generate preliminary data for statistical considerations and estimations on the probability of success of HERMES.

- mRNA expression of proinflammatory cytokines (MAPK/eNOS, adiponectin, hsCRP, MMP-9) [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: No ]Biomarkers of sub-clinical inflammation and cardiovascular risk: Change in Macrophage activation, MAPK/eNOS production levels, adiponectin and hsCRP (after test meal) from baseline to endpoint
- Insulin [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: No ]Change in Insulin and the ratio from baseline to endpoint
- HbA1c [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: No ]Blood glucose control: Change during test meal, HbA1c and FBG from baseline to endpoint
- Fasting blood glucose [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: No ]Blood glucose control: Change during test meal, HbA1c and FBG from baseline to endpoint
- Hypoglycemic events [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: Yes ]Incidence of hypoglycemia from baseline to endpoint
- intact Proinsulin [ Time Frame: Baseline, after 10 weeks, after 24 weeks ] [ Designated as safety issue: No ]Change in intact Proinsulin and the ratio from baseline to endpoint
