Hyperglycemia, Prediabetes
Conditions
Brief summary
In this trial, the investigational product , the active ingredients which has been proven to reduce postprandial glucose in healthy and diabetic patients, will be tested. The primary aim of this clinical study is to evaluate the possibility of the investigational product to reduce the rise of postprandial glucose AUC level in overweight Caucasian subjects with normal to prediabetic biomarkers (IFG/HbA1C), without prompting a disproportionate rise in insulin levels.
Interventions
Dose 1 (D1) group will take 2 tablets with active ingredients and 2 placebo tablets.
Dose 2 (D2) group will take 4 tablets with active ingredients.
Placebo group will take 4 placebo tablets. The placebo is designed to be identical to IQP-VV-102.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage change in raised postprandial glucose (PPG) AUC levels of the verum groups (dose D1 and dose D2) compared against the placebo among normal to prediabetic overweight Caucasian subjects. | 120 minutes | Measures raised PPG AUC levels (mmol/L) from 0-120 minutes on each visit |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in incremental PPG AUC level (mmol/L) | 120 minutes | Measured from 0-120 minutes after intake of verum or placebo on recruited subjects on each of the 3 visit days. |
| Change in total and incremental PPG AUC level (mmol/L) | 180 minutes | Measured from 0th minute, to 60th, 90th and 180th minute after intake of verum or placebo on subjects on each of the 3 visit days. |
| Changes in PPG concentration | 180 minutes | Measured at 15, 30, 45, 60, 90, and 120 minutes after intake of verum or placebo on recruited subjects on each of the 3 visit days. |
| Dose response of PPG level | Measured after intake of verum or placebo on recruited subjects on each of the 3 visit days. | — |
| Global evaluation of tolerability both by investigator and subjects | Throughout the study (8-14 days) | Global scaled evaluation with very good, good, moderate and poor |
| Dose response of insulin level | Measured after intake of verum or placebo on recruited subjects on each of the 3 visit days. | — |
| Change in total and incremental AUC triglyceride level | 180 minutes | Measured from 0-180 minutes after intake of verum or placebo on recruited subjects on each of the 3 visit days. |
| Incidence of adverse events (Safety parameters evaluation) | Throughout the study period (8-14 days) | Eg. Liver Function Test, Lipid parameters, Renal Function Tests. |
| Reported adverse events | Throughout the whole study period (8-14 days) | For any adverse event, the term of the event, intensity, duration, seriousness, frequency, outcome and assessment of causality with the investigational product will be documented in the Case Report Form (CRF) |
| Change in total and incremental AUC insulin level (mmol/L) | 180 minutes | Measured from 0th minute to 120th and 180th minutes after intake of verum or placebo on recruited subjects on each of the 3 visit days. |
