A Research Study on How NNC0487-0111, a New Medicine, Works in Chinese Participants When Injected Under the Skin.

The study is testing a new medicine (NNC0487-0111) for weight control in Chinese people with BMI between 24 kilogram per meter square (kg/m2) and 34.9 kg/m2. The aim of the study is to see how safe the study medicine is and how it behaves in human body. Participants will either get the study medicine or placebo (a \"dummy medicine\" similar to the study medicine but without active ingredients) and which treatment they get is decided by chance. The study medicine is a potential new medicine which cannot be prescribed by doctors but has previously been tested in humans. This study will last for up to 53 days.
