A Research Study to See if Kidney Damage in People With Chronic Kidney Disease and Type 2 Diabetes Living With Overweight or Obesity Can be Reduced by CagriSema Compared to Semaglutide, Cagrilintide and Placebo

This study will look if CagriSema can lower kidney damage in people with chronic kidney disease (CKD), type 2 diabetes (T2D) and overweight or obesity. CagriSema is a new investigational medicine. CagriSema cannot yet be prescribed by doctors. The study will compare CagriSema to the 2 medicines semaglutide and cagrilintide, when they are taken alone. It will also compare CagriSema to a "dummy" medicine (also called placebo) without any active ingredient. Participant will either get CagriSema, semaglutide, cagrilintide or placebo. Which treatment participant will get is decided by chance (like flipping a coin). Study doctor will not know which of the study medicines participant will get. For each participant, the study will last for about 35 weeks.
