Brief Summary
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.

Outcome Measures
Primary Outcomes (3)
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.
Baseline, month 8
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.
Baseline, month 8
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.
Baseline, month 8
Secondary Outcomes (2)
Change in Insulin Sensitivity
Baseline, month 8
Change in Renal Vascular Resistance (RVR)
Baseline, month 8
Study Arms (2)
Semaglutide
EXPERIMENTALParticipants will receive 0.25 mg once weekly semaglutide injection for 4 weeks. Participants will receive 0.50 mg once weekly semaglutide injection for 4 weeks. Participants will receive 1.0 mg once weekly semaglutide injection for 6 months.
Placebo
PLACEBO COMPARATORParticipants will receive 0.25 mg once weekly placebo injection for 4 weeks. Participants will receive 0.50 mg once weekly placebo injection for 4 weeks. Participants will receive 1.0 mg once weekly placebo injection for 6 months.
