NCT07573163

Brief Summary

Mild Autonomous Cortisol Secretion (MACS) is a condition in which an adrenal gland produces excess cortisol and is associated with high blood pressure, diabetes, and weight gain. Surgical removal of the adrenal gland (adrenalectomy) is standard treatment, but some patients continue to have metabolic health problems after surgery. This randomized study will evaluate whether treatment with tirzepatide after adrenalectomy improves metabolic outcomes in patients with MACS compared with adrenalectomy alone.

    Changes in blood pressure will be assessed based on patients' average blood pressure readings, mmHg

    Baseline and 12 months

Secondary Outcomes (5)

  • weight

    Baseline and 12 months

  • medication

    Baseline and 12 months reported in WHO defined daily doses (DDDs)

    Baseline and 12 months, %

  • quality of life metrics

    Baseline and 12 months

  • BMI

    Baseline and 12 months

Study Arms (2)

GLP-1 Treatment

ACTIVE COMPARATOR

GLP-1 dose of 2.5 mg once weekly for 4 weeks. The dose will then be titrated every 4 weeks based on patient tolerance to 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg.

Drug: Tirzepatide

Standard of Care arm

ACTIVE COMPARATOR

Participants in this arm will receive standard of care management for as determined by their treating clinician.

Other: Standard medical treatment

Interventions

Tirzepatide will be initiated at the lowest dose of 2.5 mg once weekly for 4 weeks. The dose will then be titrated every 4 weeks based on patient tolerance to 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg.

GLP-1 Treatment

Participants will receive postoperative care and follow up per institutional standard-of-care practices

Data Sharing

IPD Sharing
Will not share

Individual participant data (IPD) will not be publicly shared because the study involves a small sample size from a single center with detailed clinical, laboratory, and imaging data, which may pose a risk of participant re-identification despite de-identification procedures. Aggregate results will be reported in peer-reviewed publications.
