Study Details

Study Description

Brief Summary

Approximately 450 patients will be randomized to receive mifepristone or placebo for 7 days followed by antidepressant. The purpose is to compare the efficacy of mifepristone followed by antidepressant versus placebo followed by antidepressant in reducing psychotic symptoms in patients with a diagnosis of psychotic depression.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

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.

  • Outcome Measures

    Primary Outcome Measures

    1. Proportion of Mifepristone vs. Placebo Treated Patients With at Least a 50% Reduction From Baseline in Brief Psychiatric Rating Scale-Positive Symptom Subscale (BPRS-PSS) at Days 7 and 56 [56 days]

      Response as measured by 50% reduction in psychosis at Days 7 and 56 was compared between the group administered placebo and the group administered mifepristone

    Secondary Outcome Measures

    1. Proportion of Mifepristone Treated Patients With Plasma Drug Concentrations Equal to or Above 1637 ng/mL vs. Placebo Treated Patients Who Achieve a ≤ 50% Reduction in BPRS-PSS at Days 7 and 56 [56 days]

      Response as measured by 50% reduction in psychosis at Days 7 and 56 was compared between the group administered placebo and the group who achieved a sufficiently high plasma level of mifepristone

    • Have previously participated in a clinical trial of mifepristone

    • Have a history of an allergic reaction to mifepristone

    • Are in the investigator's opinion not appropriate for participation in the study or may not be capable of following the study schedule for any reason
