Obesity
Conditions
Brief 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.

Inclusion criteria
* Age of 18 to 65 years (inclusive) * Male or female subjects with obesity (defined as a body mass index (BMI) of ≥30 and ≤45 kg/m²) * Woman of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria and instructions on the duration of use is provided in the participant information * Signed and dated written informed consent in accordance with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use - Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial * In the investigator's opinion, are well-motivated, capable, and willing to: * Learn how to self-inject the investigational medicinal product (IMP), as required for this protocol (persons with physical limitations who are not able to perform the injections must have the assistance of an individual trained to inject the IMP) * Inject the IMP or accept injection from a designated person --- Follow trial procedures for the duration of the trial, including, but not limited to: follow lifestyle advice (for example, dietary restrictions and exercise, maintain a diary, complete required questionnaires, and handle the IMP as described in the instruction for use (IFU))
Exclusion criteria
* Current or history of significant alcohol consumption (defined as intake of \>210 g/week in men and \>140 g/week in women on average over a consecutive period of more than 3 months) or are unwilling to stop alcohol consumption 48 h before admission to the research facility and until discharge * History of chronic liver disease / cirrhosis * Body weight variation (self-reported) \>5% within 3 months before Visit 1 (screening) * Medications for obesity (including over-the-counter medications) within 3 months before Visit 1 (screening) * Glycated haemoglobin (HbA1c) ≥6.5% (≥48 mmol/mol) as measured by the local laboratory at screening * History of type 1 diabetes mellitus (T1DM) or T2DM or treatment with glucose lowering agent started within 3 months before Visit 1 (screening) Further
