Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To detect changes in appetite/hunger after administration of obeticholic acid compared to placebo.;Secondary Objective: (1)To detect changes in the release of gastrointestinal peptide after administration of obeticholic acid compared to placebo. (2)To detect changes in gastric motility, accommodation after administration of obeticholic acid compared to placebo. (3)To detect changes in gut microbiota after administration of obeticholic acid compared to placebo. ;Primary end point(s): -Appetite-related sensations compared between placebo and treatment with obeticholic acid;Timepoint(s) of evaluation of this end point: The volunteers have 8 visits for this study. A motility test and an endoscopy are performed before and at end of each treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Gastrointestinal hormone release compared between placebo and treatment with obeticholic acid - Gastric motility, accommodation compared between placebo and treatment with obeticholic acid - changes in gut microbial diversity abundance of specific bacteria compared between placebo and treatment with obeticholic acid ;Timepoint(s) of evaluation of this end point: The volunteers have 8 visits for this study. A motility test and an endoscopy are performed before and at end of each treatment. | — |
