Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 1. To assess whether linagliptin compared with placebo improves arterial stiffness in treatment naïve subjects with type 2 diabetes.;Secondary Objective: 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.;Primary end point(s): Difference in mean Pulse Wave Velocity (PWV) after 26 weeks between the Linagliptin and placebo treated group.;Timepoint(s) of evaluation of this end point: 26 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Central Blood Pressure (CBP) and Augmentation Index (AI) obtained from pulse wave analysis, using Sphygmocor - Carotid-(left) radial arterial PWV, using Sphygmocor - Body Mass Index (BMI) and Waist-to-Hip ratio - 24-hours ambulatory blood pressure measurement (24-ABPM) - Urinary albumin/creatinine ratio (mean of 2 separate morning portions (ACR) - plasma markers of inflammation ( i.e. high-sensitivity C-reactive protein (hs-CRP); Interleukin-6; TNF-a, serum amyloid-A (SAA), myeloperoxidase (MPO)) - plasma markers of endothelial dysfunction (i.e. vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), soluble E-selectin, von Willebrand factor, tissue-type plasminogen activator), in vitro stimulated cytokine production by peripheral blood mononuclear cells (PBMC) - Glycemic indices: fasting glucose (FPG) and 2-hour post OGTT glucose (OGTT), HbA1c, fasting insulin, and derived indices (HOMA-ß (as a surrogate marker for ß –cell function) and HOMA-IR (insulin resistance), Matsuda index (insulin sensitivity) - Skin AGE deposition measured as skin autofluorescence using AGE reader and plasma levels of AGEs (N(e)-(carboxymethyl) lysine (CML), N(e)-(Carboxyethyl) lysine (CEL) - Intake of energy, Eating behaviour, and Physical activity - Target-to-background ratios (TBRs) (18)F-fluorodeoxyglucose positron emission tomography computed tomography coregistration (FDG PET-CT);Timepoint(s) of evaluation of this end point: 4, 26, and 30 weeks | — |
