Overview
This study will compare the efficacy and safety of the two 11β-hydroxylase inhibitors-metyrapone and osilodrostat-in patients with MACS.
Primary outcome To compare the efficacy (biochemical and clinical) of the two 11β-hydroxylase inhibitors (CYP11B1), metyrapone and osilodrostat, in patients with MACS not treated surgically (mainly bilateral adenomas or adrenal hyperplasias), as well as their side effects at time 0-, 3- and 6-months post-treatment.
Secondary outcome To evaluate alterations in clinical parameters (Blood Pressure, Body Mass Index-BMI), metabolic parameters (fasting blood glucose, insulin, Hb1Ac, HOMA, OGTT and lipids levels) at time 0-, 3- and 6-month after the initiation of the treatment and their effect on Bone Mineral Density (BMD) 1 year post-diagnosis
