Brief summary
Randomized, double-blind, placebo-controlled study aimed at evaluating the effects of a 3-months treatment with Policaptil Gel Retard on postprandial incretin hormones release and satiety in obese women
Detailed description
Double-blind, randomized, placebo-controlled, parallel-group study. This study will in made of 3 phases: * The assessment of standard dose (3 tablets) of Libramed or placebo on the incretin hormones release and satiety sensation in obese women after ingestion of four test meal administered with one day interval - run-in period, to assess incretin hormones release and satiety sensation in obese women * A double-blind phase in which the treament with Libramed/Placebo will be administered for 3 months. * A post (3-months) treatment assessment of the incretin hormones release and satiety sensation after ingestion of four test meals - follow-up period. During the screening visit (V1, Week -1) patients will be evaluated with regard to the inclusion and exclusion criteria that will permit their entry into the run-in period. The results of the laboratory analyses such as lipids, glucose and insulin levels needed to check subjects' eligibility at the time of randomization \[baseline visit (V2)\] will be performed at the screening visit. The run-in period starts on day 2 of the menstrual cycle and ends not later than 12 days of menstrual cycle. During the four visits of run-in period (V2, V3, V4 and V5) will be assessed the effect of double-blind single dose of Libramed or placebo on postprandial incretin axis activity, glucose and triglycerides levels, satiety feeling and subsequent food consumption in relation to macronutrients content in test meals intake. During the visit V2 patient will be trained on diary completion. On the first visit of this period (V5) patient previously randomized on the first visit of the run-in period (V2) will receive the first kit of Libramed or placebo. Each patient will self-administer 3 tablets of Libramed or placebo 2 times per day 15 minutes before breakfast and lunch. The dose of Libramed or placebo will be stable during the treatment period. During the visit V5 patient will be trained on the Libramed or placebo self-administration, patient's diary completion and on diet and physical activity recommendation. The follow-up period includes four visits (from V9 to V12), in the week immediately after the last intake of Libramed or placebo. The first visit of the follow-up period (V9) will take place the day immediately after the last intake of Libramed or placebo. The visits 9 to 12 (V9, V10, V11, V12) will take place with one day interval from each other, during the week after the last dose of Libramed or placebo use. On these visits the test meals will be administered and postprandial incretin axis, glucose and triglycerides levels as well as satiety feeling will be assessed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of postprandial incretin axis activity | day 1 to day 91 | incretin axis activity |
| Evaluation of postprandial glycemic profile | day 1 to day 91 | blood samples for glucose measurements ( will be collected on visits 1, 2, 3, 4 and 8, 9, 10, 11, 12 on the fasting state and during the postprandial 6-hours observations (6 time collections 1, 2, 3, 4, 5, 6 hours after the test meal intake). |
| Evaluation of triglycerides levels | day 1 to day 91 | Blood samples for triglycerides measurements will be collected on visits 1, 2, 3, 4 and 8, 9,10,11,12 on the fasting state and during the postprandial 6-hours observations (6 time collections 1, 2, 3, 4, 5, 6 hours after the test meal intake). |
| Evaluation of satiety feeling | day 1 to day 91 | On visit 2 and 8 the subjective fasting satiety and hunger sensation will be assessed on the basis of visual analogue scale (VAS) at the baseline (V2) and at the end of the double-blind treatment period (V8). In addition fasting and postprandial VAS scales will be filled by the test 5 minutes before Libramed product or placebo administration, 5 minutes before eating a test meal and 1, 2, 3, 4, 5, 6 hour after test meal consumption during the run-in period (V5) and follow-up period (V9-V12). |
Secondary
| Measure | Time frame | Description |
