A Research Study on How Well Semaglutide Works in Adolescents With Overweight or Obesity
- Registration Number
- NCT04102189
- Lead Sponsor
- Novo Nordisk A/S
- Brief Summary
This study will look at the change in teenagers' body weight from the start to the end of the study. This is to compare the effect on body weight in teenagers taking semaglutide (a new medicine) and teenagers taking "dummy" medicine. The teenagers in the study and their parents will also have talks with study staff about healthy food choices, how to be more physically active and what they can do to help the teenagers lose weight. The teenagers will either get semaglutide or "dummy" medicine - which treatment is decided by chance. The teenagers will take 1 injection every week, on the same day of the week for about 15 months. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The teenagers will have 17 clinic visits, will have blood samples taken and will have to complete questionnaires and keep a diary. All this will be explained before study start.

Change in BMI (Standard Deviation Score [SDS]) Baseline (week 0), week 68 Change in BMI SDS from baseline to week 68 is presented. The SDS scores are also called as z-scores.

For each subject, a standard deviation score Z (SDS) was calculated based on age and sex referring to the values L, M and S. The method is described in the world health organisation (WHO) Multicentre Growth Reference, which also contains the values for L, M and S by age and sex. For Z (SDS) scores below -3 and above 3, the score was adjusted as described in the WHO instruction. Possible values range from -3 to +3, a negative score being beneficial.
