E.2.2 | Secondary objectives of the trial |
2. To assess whether linagliptin compared with placebo improves blood pressure parameters, inflammatory and endothelial function markers, albuminuria, and vascular inflammation in treatment naïve subjects with type 2 diabetes. 3. To determine whether the off-target effects on arterial stiffness blood pressure parameters, inflammatory endothelial function markers and vascular inflammation are concordant with changes in glucose parameters, including HbA1c fasting plasma glucose, and beta-cell and insulin sensitivity indices. |
2. Beoordelen of linagliptin in vergelijking met placebo de bloeddruk parameters, ontstekings-en endotheelfunctie markers en albuminurie bij behandelingsnaïeve patiënten met type 2 diabetes verbetert. 3.
