NCT05819138

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

EXPERIMENTAL

Participants 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.

Drug: Semaglutide Pen Injector

Placebo

PLACEBO COMPARATOR

Participants 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.

Drug: Placebo
