Introduction: The steroidogenesis inhibitor osilodrostat (OSI), indicated for the medical treatment of endogenous Cushing’s syndrome, exhibits significant interindividual variability regarding the response to treatment (Pivonello et al. 2020). Plasma exposure may contribute to this variability. Our objective was to investigate the effect of concomitant use of mitotane (MIT), a potent inducer of CYP450 (3A4), on circulating OSI concentrations in patients treated f...

Introduction: The steroidogenesis inhibitor osilodrostat (OSI), indicated for the medical treatment of endogenous Cushing’s syndrome, exhibits significant interindividual variability regarding the response to treatment (Pivonello et al., 2020), a fortiori in the context of adrenocortical carcinoma (Tabarin et al., 2022). Plasma exposure may contribute to this variability. Our objective was to investigate the effect of concomita...
