E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To study by 2-step hyperinsulinemic euglycemic clamp (HEC), the effects of metformin, fenofibrate and their combination on: 1°) Endogenous Glucose Production (EGP), and 2°) Glucose Disposal Rate (GDR). HEC will be performed according to the standardized procedure used for the EGIR-RISC Project (European Group for the Study of Insulin Resistance - Relationship between Insulin Sensitivity and Cardiovascular disease). |
|
E.2.2 | Secondary objectives of the trial |
To investigate the effects of metformin, fenofibrate and their combination on: - Gluconeogenesis (GNG) - Glycogenolysis (GGL) - Skeletal muscle and liver fat content measured by magnetic resonance spectroscopy (MRS) - Abdominal fat content measured by magnetic resonance imaging (MRI) - Body energy expenditure and respiratory quotient measured by indirect calorimetry - Lipids, lipoproteins and carbohydrate metabolism and other biochemical parameters - Other safety test parameters. |

E.5 End points |
E.5.1 | Primary end point(s) |
Main primary criteria, percent change of low-dose insulin-suppressed EGP as investigated by HEC (µmol/kgffm/min; where kgffm is the fat-free mass in kg). Other primary criteria, percent change of: - Basal EGP (µmol/kgffm/min), - High-dose insulin-suppressed EGP (µmol/kgffm/min), - Basal GDR (same as basal EGP; µmol/kgffm/min), - Low-dose insulin-stimulated GDR (µmol/kgffm/min), - High-dose insulin-stimulated GDR (µmol/kgffm/min). |
