A Study of Mifepristone vs. Placebo in the Treatment of Patients With Major Depression With Psychotic Features

Up to 450 patients with psychotic depression will be randomly assigned to receive either mifepristone or matching placebo. Patients will be assessed by the investigator or site staff during screening and on study days. A single antidepressant selected from a list of approved drugs will be administered after the administration of investigational drug. Adverse events, laboratory assessments, electrocardiograms, and physical examinations will be used to assess safety.
