| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| To compare the two-year effect of semaglutide s.c. 2.4 mg once weekly versus semaglutide placebo as an adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or obesity on body weight. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
1. To compare the two-year effect of semaglutide s.c. 2.4 mg once weekly versus semaglutide placebo as an adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or obesity on:
 - Cardiovascular risk factors
 - Glucose metabolism
 2. To compare the one-year effect of semaglutide s.c. 2.4 mg once weekly versus semaglutide placebo as an adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or obesity on body weight
 3. To compare the two-year safety and tolerability of semaglutide s.c. 2.4 mg once weekly versus semaglutide placebo as an adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or obesity. |
