A Research Study on How Well Cagrilintide and CagriSema Work in Children and Adolescents With Excess Body Weight

United States, Australia, Austria460 participantsStarted 2026-01-08

Plain-language summary

This study will look at how well CagriSema and cagrilintide help children and adolescents with excess body weight lose weight. The study has 2 parts: main and extension study. In the main study, participants will either get CagriSema (a new study drug), cagrilintide (a new study drug), semaglutide (a drug that doctors can already prescribe to adolescents and adults) or placebo (a placebo looks like the treatment being tested, but doesn't have any active ingredients in it). Which treatment participants will get is decided by chance. Participants who get semaglutide in the main study will not take part in the extension study. If participants take part in the extension study, they will get either CagriSema or cagrilintide in this part of the study. Like all drugs, the study drugs may have side effects. The total time participants will be in the main study is about 1 year and 6 months. If participants take part in the extension study, the total time is about 4 years and 10 months.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
