Summary

"This trial aims to see how semaglutide affects kidney function and oxygen levels in people with type 1 diabetes. It will also look at how semaglutide impacts blood sugar levels and safety

Who is the study for?
This trial is for adults over 18 with type 1 diabetes who have had the condition for at least five years and are showing signs of kidney disease. They must have stable blood pressure and cholesterol medication use, and women able to have children need to use birth control.
What is being tested?
The study tests if Semaglutide can improve kidney oxygenation and function in people with type 1 diabetes. It also looks at how it affects blood sugar levels and its overall safety compared to a placebo (a treatment with no active drug).
What are the potential side effects?
Possible side effects of Semaglutide may include nausea, vomiting, diarrhea, abdominal pain, low blood sugar events, potential allergic reactions, or injection site reactions.
