This study is testing a new medicine called cagrilintide to see if it helps people with extra body weight lose weight. Participants will get either cagrilintide or a placebo (a fake treatment with no real medicine). Which one they get will be decided by chance, like flipping a coin. Cagrilintide is still being tested and isn't available from doctors yet. This study will last about 9 months.
- **Participation Length**: About 9 months.
- **Eligibility**: Must be 18+ years old and have certain body weight conditions.
- **Restrictions**: Cannot have diabetes or be on certain weight loss medicines recently.
