About this trial
This trial plans to learn more about the effects of a medication, semaglutide, on cardiovascular function, kidney function, and insulin sensitivity in adults with type 1 diabetes. This medication has been effective in reducing cardiovascular disease and diabetic kidney disease and improving glucose control and BMI in adults with type 2 diabetes. This study aims to look at how well the medication works in people with type 1 diabetes. Semaglutide is not approved by the FDA to be used in this way. These procedures are considered to be experimental.

Trial outcomes
Primary outcomes
Change in Ascending Aortic Pulse Wave Velocity (AA PWV)
AA PWV is a measure of central arterial stiffness. A lower value indicates a better outcome.
Change in Carotid and Femoral Artery Pulse Wave Velocity (CF-PWV)
CF-PWV is a measure of peripheral arterial stiffness. A lower value indicates a better outcome.
Change in Carotid and Radial Artery Pulse Wave Velocity (CR-PWV)
CR-PWV is a measure of peripheral arterial stiffness. A lower value indicates a better outcome.
Secondary outcomes
Change in Insulin Sensitivity
Insulin Sensitivity is a measure of how well the body responds insulin. A higher value indicates a better outcome; a lower value indicates a worse outcome.
Change in Renal Vascular Resistance (RVR)
RVR is a measure of mean arterial pressure to renal blood flow. A higher value indicates a worse outcome.
