Brief Summary:
This is a multicenter, randomized, double-blind, placebo-controlled parallel-group, fixed-dose study in patients with a primary diagnosis of MDD according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) who have an inadequate response to ongoing ADT.

Condition or disease Intervention/treatment Phase
Major Depressive Disorder Drug: Lumateperone Drug: Placebo Phase 3

Detailed Description:

The study will be conducted in three periods:

  • Screening Period (up to 2 weeks) during which patient eligibility will be assessed.
  • Double-blind Treatment Period (6 weeks) in which all patients will be randomized to receive placebo or lumateperone 42 mg/day in 1:1 ratio.
  • Safety Follow-up Period (1 week) in which all patients will return to the clinic for a safety follow-up visit approximately one week after the last dose of study treatment.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Montgomery-Asberg Depression Rating Scale [ Time Frame: Day 43 ]
    The MADRS is a clinician-rated 10 item scale to assess depressive symptoms. Each item is rated on a 7-point scale from 0-6. The total score ranges from 0 to 60 with a higher score indicating increased severity of depressive symptoms.


Secondary Outcome Measures :
  1. Clinical Global Impression Scale-Severity [ Time Frame: Day 43 ]
    The CGI-S is a clinician-rated scale to assess a patient's overall mental health. The scale ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
