A Study to Test Whether Survodutide Improves How the Body Uses Energy and Breaks Down Fat in People With Obesity

United States64 participantsStarted 2025-03-26

Plain-language summary

This study is open to adults between 18 and 65 years of age who have obesity. People can join the study if they have a body mass index (BMI) between 30 and 45 km/m². The purpose of this study is to find out whether a medicine called survodutide improves how the body uses energy and breaks down fat. This study compares survodutide with another medicine called semaglutide. Survodutide is being developed to treat people with obesity. Semaglutide is already used to treat people with obesity. Participants are put into 2 groups by chance. One group gets survodutide and the other group gets semaglutide. Participants get survodutide or semaglutide as an injection under the skin once a week. Participants are in the study for 8-10 months depending on how long the treatment is given. During this time, they visit the study site weekly. Some of the visits may also be done at the participant's home instead of the study site. At some of the visits, doctors test how much energy a participant's body uses. This is done in a special room where they measure the oxygen that is breathed in and the carbon dioxide that is breathed out by the participant. The results are compared between the 2 groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

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.

What they're measuring

Absolute change in sleeping metabolic rate (SMR) (measured in a whole room calorimeter) from baseline to first visit a participant reached at least 10% weight loss
