Clinical Trial Summary

This study will look at how well semaglutide helps children and teenagers losing weight. This will be tested by comparing the effect on body weight in children and teenagers taking semaglutide in comparison to placebo, a "dummy" medicine. In addition to taking the medicine, the child's parent and the child will have talks with study staff about healthy food choices, how to be more physically active and what your child can do to try to lose weight. The child will either get semaglutide or a "dummy" medicine. Which treatment the child will get is decided by chance. Semaglutide is an approved medicine for type 2 diabetes and weight management in adults.

The child will get one injection once a week. The study medicine is injected with a thin needle in the stomach, thighs or upper arms. The study will last for about 2 ½ years (132 weeks).

• History of at least one unsuccessful effort to lose sufficient body weight after participation in a structured lifestyle modification programme (diet and exercise counselling) for at least 3 months

• Body weight of greater than 45 kilogram (kg) at screening and randomisation

• For participants with T2D at screening, the following additional criterion applies:

glycated haemoglobin (HbA1c) less than or equal to 10.0 percent (86 millimoles per mole [mmol/mol]) as measured by central laboratory at screening

Exclusion Criteria:

• Treatment with any medication prescribed for the indication of obesity or weight management within 90 days before screening

• Previous or planned (during the study period) obesity treatment with surgery or a weight loss device. However, the following are allowed: a) liposuction and/or abdominoplasty, if performed greater than 1 year prior to screening. b) adjustable gastric banding, if the band has been removed greater than 1 year prior to screening. c) intragastric balloon, if the balloon has been removed greater than 1 year prior to screening. d)duodenal-jejunal bypass liner (e.g., nonbarrier), if the sleeve has been removed greater than 1 year prior to screening

• Type 1 diabetes mellitus or monogenic diabetes

• Participants with endocrine, hypothalamic, or syndromic obesity

• For participants with T2D at screening, the following additional key criterion applies: Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a fundus examination performed within the past 90 days before screening or in the period between screening and randomisation. Pharmacological pupil-dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination
