Background

Cushing's syndrome (CS) is underpinned by chronic hypercortisolism leading to multisystem morbidity, including effects on the cardiovascular and endocrine systems, metabolic syndrome with accompanying changes in body composition, neuropsychiatric effects, changes in blood pressure and chemistry, and opportunistic infections. Ketoconazole has been used both on- and off-label to treat CS due to its ability to inhibit cortisol production. Still, toxicity has limited its use, notably hepatic toxicity and a tendency to prolong the QT interval. Levoketoconazole is one of two enantiomers present in racemic ketoconazole. It possesses most of the inhibitory effect towards steroidogenic enzymes, making it an attractive candidate for CS treatment with a potentially lower toxicity profile than its racemate.

Levoketoconazole was approved by the FDA on December 30, 2021, and is currently marketed under the registered trademark RECORLEV by Xeris Pharmaceuticals, Inc.

Indication

Levoketoconazole is indicated for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not been curative. Levoketoconazole is not indicated for the treatment of fungal infections.
