Curator's Comment: The description was created based on several sources, including https://clinicaltrials.gov/ct2/show/NCT02697734 | https://clinicaltrials.gov/ct2/show/NCT02468193 | https://clinicaltrials.gov/ct2/show/NCT02372084 | https://www.ncbi.nlm.nih.gov/pubmed/25981165

Osilodrostat (INN, USAN) (developmental code name LCI-699) is an orally active, non-steroidal corticosteroid biosynthesis inhibitor which is under development by Novartis for the treatment of Cushing's syndrome and pituitary ACTH hypersecretion (a specific subtype of Cushing's syndrome). Osilodrostat specifically acts as a potent and selective inhibitor of aldosterone synthase (CYP11B2) and at higher dosages of 11β-hydroxylase (CYP11B1). Osilodrostat decreases plasma and urinary aldosterone levels and rapidly corrects hypokalemia, in patients with primary aldosteronism and hypertension. At doses ≥1 mg o.d. Osilodrostat markedly increases 11-deoxycortisol plasma levels and blunts ACTH-stimulated cortisol release in ≈20% of patients, consistent with the inhibition of CYP11B1. In patients with resistant hypertension, Osilodrostat produces a non-significant reduction in blood pressure, possibly due to the increase in 11-deoxycortisol levels and the stimulation of the hypothalamic-pituitary-adrenal feedback axis. Because of the lack of selectivity, poor antihypertensive effect, and short half-life, the development of Osilodrostat as antihypertensive was halted. As of 2017, Osilodrostat is in phase III and phase II clinical trials for the treatment of pituitary ACTH hypersecretion and Cushing's syndrome, respectively.

In Vivo Use Guide

1, 5, 10, or 20 mg/day for 48-weeks

Route of Administration: Oral

In Vitro Use Guide

For in vitro measurement of aldosterone activity, human adrenocortical carcinoma NCI-H295R cells are seeded in NBS 96-well plates at a density of 25,000 cells/well in 100 μl of a growth medium containing DMEM/F12 supplemented with 10% FCS, 2.5% Nuserum, 1 μg ITS/ml, and 1x antibiotic/antimycotic. The medium is changed after culturing for 3 days at 37 C under an atmosphere of 5% CO2/95% air. On the following day, cells are rinsed with 100 μl of DMEM/F12 and incubated with 100 μl of treatment medium containing 1 µM Ang II and a compound 7n (Osilodrostat) at different concentrations in quadruplicate wells at 37C for 24 hr. At the end of incubation, 50 μl of medium is withdrawn from each well for measurement of aldosterone production by an RIA using mouse anti-aldosterone monoclonal antibodies.
