Arm Intervention/treatment
Experimental: Cariprazine 1.5 mg
During the double blind treatment period (6 weeks), participants will take 1 capsule of cariprazine 1.5mg, orally, per day in addition to their ongoing ADT (Same antidepressant and dose of ADT they were on at the Visit 2 baseline.)
 Drug: Cariprazine
Cariprazine supplied in capsules
Experimental: Cariprazine 3 mg
During the double blind treatment period (6 weeks), participants will take 1 capsule of cariprazine 1.5mg, orally, per day for two weeks in addition to their ongoing ADT (Same antidepressant and dose of ADT they were on at the Visit 2 baseline). They will then titrate to Cariprazine 3 mg, orally per day, in addition to their ADT starting at Visit 4 (Week 2)
 Drug: Cariprazine
Cariprazine supplied in capsules
Placebo Comparator: Placebo
During the double blind treatment period (6 weeks), participants will take 1 capsule of placebo, orally, per day in addition to their ongoing ADT (Same antidepressant and dose of ADT they were on at the Visit 2 baseline.)
 Drug: Placebo
Placebo supplied in capsules


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. Total score change from baseline to Week 6 in the MADRS (Montgomery-Åsberg Depression Rating Scale) [ Time Frame: 6 Weeks ]
    The MADRS is a 10-item, clinician-rated scale that evaluates the patient's depressive symptomatology during the past week. Patients are rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. Each item is scored on a 7-point scale with a score of 0 reflecting no symptoms and a score of 6 reflecting symptoms of maximum severity.

Criteria

Inclusion Criteria:

  • Written informed consent has been obtained
  • Written documentation has been obtained in accordance with the relevant country and local privacy requirements, where applicable (eg, Written Authorization for Use and Release of Health and Research Study Information [US sites] and written Data Protection consent [EU sites])
  • Patient must be an outpatient at the time of Visit 1 (Screening)
  • Patient meets the DSM-5 criteria for MDD based on SCID-5, with a current major depressive episode of at least 8 weeks and not exceeding 18 months in duration at Visit 1/Screening. A diagnosis of MDD with psychotic features will be acceptable.
  • Diagnosis of MDD confirmed through a formal adjudication process (see Section 6.1)
  • Patient demonstrates ability to follow study instructions and likely to complete all required visits
  • Patient must have an inadequate response, as measured by the modified ATRQ, to 1 to 3 antidepressants administered during the current episode at an adequate dose (as per package insert) and for at least 6 weeks duration, with at least one dose escalation during the current depressive episode.
  • Only one antidepressant (of sufficient dose per package insert and taken for at least 6 weeks) will be allowed at randomization and patients must agree to continue taking the same ADT dosing regimen through completion of Visit 6/ET. Patients who are taking more than one antidepressant at Screening, regardless of the indication, will need to discontinue all other antidepressants prior to Visit 2 (Baseline).
  • Male and female patients must agree to use a medically acceptable and highly effective method of birth control during the course of the entire study
  • Women of childbearing potential (only) must have a negative serum β-human chorionic gonadotropin pregnancy test prior to Visit 2

Exclusion Criteria:

  • Diagnosis of any current psychiatric diagnosis other than MDD (including those with current intellectual development disability) with the exception of specific phobias
  • Patient has a history of intolerance or hypersensitivity to cariprazine or other drugs of the same class or to rescue medications
