Can a diabetes drug replace surgery for a rare hormone disorder?
NCT ID NCT07361874
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two treatments for mild autonomous cortisol secretion (MACS), a condition where the body makes too much cortisol. Researchers want to see if removing the adrenal gland (surgery) or taking semaglutide (a weight-loss drug) better improves insulin resistance and other health measures. About 75 adults with MACS or similar health issues will take part over 26-30 weeks.
