A Research Study to See How Semaglutide Works Compared to Placebo in People With Type 2 Diabetes and Chronic Kidney Disease

The researchers are doing this study to see if semaglutide can slow down the growth and worsening of chronic kidney disease in people with type 2 diabetes. Participants will get semaglutide (active medicine) or placebo ('dummy medicine'). This is known as participants' study medicine - which treatment participants get is decided by chance. Semaglutide is a medicine, doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine in a skin fold once a week. The study will close when there is enough information collected to show clear result of the study. The total time participants will be in this study is about 3 to 5 years, but it could be longer.

Treatment and study plan

semaglutide

Drug

Participants are to inject semaglutide with a needle in the stomach, thigh or upper arm. Participants will use a pen to inject semaglutide under their skin. Participants will inject semaglutide 1 time a week on the same day of the week. Participants' dose of semaglutide will be changed over time. Participants start by taking a smaller amount (0.25 mg). After 4 weeks the dose will be increased to 0.5 mg. It will be increased more (to 1 mg) at 8 weeks. Participants will then stay on the same dose for the rest of the study.

Placebo (semaglutide)

Drug

Participants are to inject placebo (semaglutide) with a needle in the stomach, thigh or upper arm. Participants will use a pen to inject placebo (semaglutide) under their skin. Participants will inject placebo (semaglutide) 1 time a week on the same day of the week. Participants' dose of placebo (semaglutide) will be changed over time. Participants start by taking a smaller amount (0.25 mg). After 4 weeks the dose will be increased to 0.5 mg. It will be increased more (to 1 mg) at 8 weeks. Participants will then stay on the same dose for the rest of the study.
