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.
Detailed Description
This prospective, randomized study will enroll adults with MACS and elevated blood pressure who are undergoing unilateral adrenalectomy. Following surgery, participants will be randomized in a 1:1 ratio to one of two groups: adrenalectomy alone or adrenalectomy followed by tirzepatide therapy for 12 months. Tirzepatide will be prescribed and managed by the study team in accordance with current standard-of-care practices, including routine clinical monitoring and dose adjustments. The primary focus of the study is to evaluate blood pressure control at 12 months. Secondary outcomes include change in body weight, body mass index, glycemic control, medication burden, and patient-reported quality of life. This study aims to generate preliminary data on the feasibility, safety, and potential additive metabolic benefits of combining pharmacologic incretin-based therapy with surgical management of MACS.
