IMPACT-MACS: Adrenalectomy vs Semaglutide for Metabolic Outcomes in Mild Autonomous Cortisol Secretion (NCT07361874)

IMPACT-MACS Study: Investigating the Mechanisms, Pathophysiology, and Cardiometabolic Treatment in Mild Autonomous Cortisol Secretion

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿ’Š Investigational Drug / Biologic Sponsor: University of Texas Southwestern Medical Center

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The goal of this study is to learn how two treatments-adrenalectomy (surgical removal of an adrenal gland) and semaglutide (a medication used for weight management)-affect insulin resistance and cortisol regulation in adults with mild autonomous cortisol secretion (MACS). The study will also learn how these treatments impact body composition, blood pressure, cholesterol, inflammation, muscle strength, and quality of life. The main questions the study aims to answer are: 1. Does adrenalectomy or semaglutide improve insulin resistance more in people with MACS? 2. How do these treatments change cortisol patterns and other cardiometabolic risk factors? 3. Do people with MACS respond differently to semaglutide compared to matched adults without MACS? Participants will: 1. Receive either adrenalectomy or semaglutide if they have MACS, or semaglutide if they are matched controls 2. Complete clinic visits and phone visits over about 26-30 weeks 3. Undergo metabolic testing such as blood tests, urine steroid profiling, body composition scans, blood pressure monitoring, muscle strength testing, and questionnaires about health and well-being
