|Condition or disease||Intervention/treatment||Phase|
|Endogenous Cushing's Syndrome||Drug: Levoketoconazole Drug: Placebo||Phase 3|
This is a double-blind, randomized, placebo-controlled withdrawal and rescue/restoration study in subjects with endogenous CS that will assess efficacy, safety, tolerability, and PK of levoketoconazole. There are two populations (cohorts) of subjects: (1) subjects which were previous levoketoconazole study completers and (2) subjects that are levoketoconazole treatment naïve subjects.
Study methodology varies by cohort prior to randomization only. Following initial screening (washout as needed) and Dose Titration and Maintenance Periods, as applicable, this study will be conducted in two double-blind phases (a Withdrawal Phase and a Restoration Phase). The levoketoconazole-naïve cohort will need to go through the Dose Titration and Maintenance Phase. The longest anticipated total study participation duration is approximately 51 weeks.
