Intervention / Treatment
Detailed Description
Primary objective:
The primary objective of the present trial is to assess the beneficial effect of Totum-63 compared to a placebo on glucose homeostasis assessed by the fasting plasma glucose level in prediabetics or untreated type 2 diabetics after 24 weeks of consumption.
Secondary objectives:
Secondary objectives of the study are to assess the efficacy of Totum-63 compared to a placebo in prediabetics or untreated type 2 diabetics after 12 and 24 weeks of consumption through the following criteria:
- Glucose homeostasis assessed by fasting plasma glucose level (after 12 weeks of consumption only), fasting blood HbA1c and fructosamine levels, OGTT (Oral Glucose Tolerance Test after 24 weeks of consumption only), insulinemic and glycemic parameters.
- Pancreatic beta-cells function and insulin sensitivity assessed by fasting blood insulin level, HOMA-IR (Homeostasis Model Assessment of Insulin Resistance), HOMA-β, QUICKI (Quantitative Insulin sensitivity Check Index), ISI-M (Matsuda-DeFronzo Insulin Sensitivity Index after 24 weeks of consumption only), OGIS (Oral Glucose Insulin Sensitivity after 24 weeks of consumption only) and PREDIM (PREDIcted M after 24 weeks of consumption only) indexes.
- Lipid homeostasis assessed by fasting blood levels of triglycerides (TG), Total Cholesterol (TC), HDL-cholesterol, LDL-cholesterol and NEFA (Non-Esterified Fatty Acids).
- Oxidation mechanism of circulating lipids assessed by the ratio fasting blood LDLox / fasting blood LDLc and the PON-1 (paraoxonase-1, arylesterase activity) activity in blood.
- Low grade inflammation assessed by fasting blood hsCRP level.
- Hepatic function assessed by fasting blood total bilirubin level, GGT, ASAT and ALAT activities in blood.
- Hemodynamics assessed by Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP).
- Anthropometrics assessed by Body Weight (BW), Waist Circumference (WC), Hip Circumference (HC) and Waist to Hip Ratio (WHR).
- Satiety assessed by the three-day food diary energy and nutrient intake parameters.
Safety objectives:
The following criteria assessed after 24 weeks of study product consumption participate to the objectives of safety check:
- Renal function assessed by fasting blood creatinine and urea level;
- Complete blood count.

They will consume 3 capsules at the beginning of their breakfast, 2 capsules at the beginning of their lunch and 3 capsules at the beginning of their dinner.
|
Placebo Comparator: Placebo
The comparative product is a placebo with the same characteristics of appearance and packaging in which all ingredients are replaced by maltodextrin.
|
