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

NCT07361874 · Sponsor: University of Texas Southwestern Medical Center

What this trial means for you

This study is recruiting now at 1 US site. It's studying Intervention 2: Semaglutide for mild autonomous cortisol secretion (macs), autonomous cortisol secretion (acs), subclinical cushing's.

Who can joinAll sexes, 18 Years and older
Healthy volunteersNo — diagnosis required
What you'd takeIntervention 2: Semaglutide
Study length~4.3 years overall
Planned participants75
TypeInterventional (you receive treatment)

What participants typically get: study medication (or placebo, if the trial uses one) and study-related medical care at no cost, plus close monitoring. Compensation for time and travel varies by study — ask the site. Note that in many trials you can't choose your treatment group, and some participants receive a placebo.

The study, in the sponsor's words

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
