New drug targets hidden hormone problem to boost heart and bone health
NCT ID NCT07247058
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the drug Isturisa can improve blood sugar, cholesterol, blood pressure, weight, and bone strength in people with mild autonomous cortisol secretion (MACS), a condition where the body makes too much cortisol. Ten adults with MACS will take Isturisa for two years and have regular check-ups. The goal is to see if the drug can reduce the health risks linked to this hormone imbalance.
