Levoketoconazole

Levoketoconazole (INN, USAN) (developmental code name COR-003; tentative brand name Recorlev, previously NormoCort), also known as (2S,4R)-ketoconazole, is a steroidogenesis inhibitor that is under development by Strongbridge Biopharma (formerly Cortendo AB) for the treatment of Cushing's syndrome.[1][2][3][4] It is currently in phase III clinical trials for this indication.[1][2] The drug is the levorotatory or (2S,4R) enantiomer of ketoconazole.[2][3][4] It is expected to have greater potency, efficacy, and safety, including a lower risk of hepatotoxicity, relative to racemic ketoconazole.[3][4]

Levoketoconazole is an inhibitor of the enzymes CYP11B1 (11β-hydroxylase), CYP17A1 (17α-hydroxylase/17,20-lyase), and CYP21A2 (21-hydroxylase).[1][2][4] It inhibits glucocorticoid biosynthesis and hence circulating levels of glucocorticoids, thereby treating Cushing's syndrome.[1][4] In addition to its increased potency, the drug is 12-fold less potent than racemic ketoconazole in inhibiting CYP7A1 (cholesterol 7α-hydroxylase), theoretically resulting in further reduced interference with bile acid production and metabolite elimination and therefore less risk of hepatotoxicity.[4] Levoketoconazole has also been found to inhibit CYP11A1 (cholesterol side-chain cleavage enzyme) and CYP51A1 (lanosterol-14α-demethylase), similarly but more potently relative to ketoconazole.[5]
