Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To detect changes in MMC activity after administration of liraglutide compared to placebo. ;Secondary Objective: 1)To detect changes in the release of gastrointestinal hormones after liraglutide compared to placebo. 2)To detect changes in hunger after liraglutide compared to placebo. 3)To detect changes in ad libitum food intake after liraglutide compared to placebo. 4)To detect changes in blood glucose levels after liraglutide compared to placebo. ;Primary end point(s): MMC activity compared between placebo and treatment with liraglutide.;Timepoint(s) of evaluation of this end point: The volunteers have 10 visits in total for this study, for each condition 5 consecutive days. At day 4 and 9 (the cross-over of conditions), the MMC is continuously measured, starting at 7 am until 1 pm. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Gastrointestinal hormone release compared between placebo and treatment with liraglutide - Hunger sensations compared between placebo and treatment with liraglutide - Ad libitum food intake compared between placebo and treatment with liraglutide - Glucose whole blood levels compared between placebo and treatment with liraglutide ;Timepoint(s) of evaluation of this end point: The volunteers have 10 visits in total for this study, for each treatment arm 5 consecutive days. Blood samples will be measured at days: 4, 5, 9 and 10. A first blood sample is taken prior to the treatment (placebo or liraglutide). For day 4 and 9 after the injection, blood samples are collected every 30 min until 1 pm. For day 5 and 10 after the injection, blood samples are collected every 30 min until 1.30 pm and one more sample at 3 pm after the ad libitum buffet. Hunger, prospective food consumption and satiety will be scored every 5 min and hunger related symptoms will be scored on VAS of 100 mm every 30 min from the start of the study until the end of the study on days 4, 5, 9 and 10. On day 5 and 10, the volunteers eat ad libitum from a free choice buffet. | — |
