Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the change from baseline to the 6 months visit at the end of treatment, between lifestyle intervention + exenatide 2 mg once weekly and lifestyle intervention + placebo, in BMI SDS (according to WHO) for adolescents with obesity. ;Secondary Objective: 1. To evaluate safety and tolerability. 2. To compare changes in beta-cell function within the groups and between the groups from baseline to the 6 months visit. 3. To compare changes in glucagon levels within the groups and between the groups from baseline to the 6 months visit. 4. To compare changes in cardiovascular risk factors and pattern changes in Free Fatty Acids (FFAs) within the groups and between the groups from baseline to the 6 months visit. 5. To compare changes in high sensitivity C-Reactive Protein (hs-CRP) within the groups and between the groups from baseline to the 6 months visit. 6. To compare changes in body composition characteristics within the groups and between the groups from baseline to the 6 months visit. 7. To compare changes in anthropometrics within the groups and between the groups from baseline to the 6 months visit. 8. To compare the change in s-BMI within the groups and between the groups from baseline to the 6 months visit. 9-11 in csp. ;Primary end point(s): BMI SDS (according to WHO). ;Timepoint(s) of evaluation of this end point: At end of study | — |
