Safety and Efficacy of Cariprazine as an Adjunctive to Antidepressant Therapy in Major Depressive Disorder
March 29, 2018 updated by: Forest Laboratories
A Double-Blind, Placebo-Controlled Study of Cariprazine (RGH-188) as Adjunctive Therapy in Major Depressive Disorder
An outpatient study to evaluate the safety and efficacy of cariprazine as adjunct to antidepressant therapy (ADT) in participants with major depressive disorder (MDD) who have an inadequate response to ADT alone.
This clinical study compared cariprazine + ADT with placebo + ADT in outpatients with a diagnosis of MDD and an inadequate response to ADT.
The study consisted of approximately 2 weeks of screening and washout followed by 8 weeks of double-blind treatment followed by a 1 week safety follow-up.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
Participants received placebo orally once a day for 8 weeks.
Each participant continued to take the same dose of antidepressant therapy (bupropion, citalopram, desvenlafaxine, duloxetine, escitalopram, fluoxetine, sertraline, venlafaxine, or vilazodone) the participant was receiving prior to entering this study throughout treatment.

Experimental: Cariprazine 1-2 mg
Participants received cariprazine orally once a day for 8 weeks.
Participants received cariprazine 0.5 mg on Days 1 and 2 and 1.0 mg on Days 3-7.
At the investigator's discretion dose levels could be increased during Week 2. Dose levels allowed during Week 2 were 1.0 or 1.5 mg.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score at Week 8
Time Frame: Baseline to Week 8
|
The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week.
Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity).
The total score ranges from 0 to 60 with a higher score indicating more depression.
A negative change score indicates improvement.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Sheehan Disability Scale (SDS) Total Score at Week 8
Time Frame: Baseline to Week 8
|
The SDS measures an individual's perception of the extent to which his or her emotional symptoms are disrupting his or her functioning in 3 domains, work/school, social life/leisure activities, and family life/home responsibilities.
The participant is asked to rate the degree to which their functioning is impaired on an 11-point scale, ranging from 0 (not at all) to 10 (extremely).
Scores of 0 to 3 indicate mild functional impairment, 4 to 6 indicate moderate functional impairment, and 7 to 9 indicate marked functional impairment.
The scores for the 3 domains are summed into a total score that ranges from 0 (unimpaired) to 30 (highly impaired).
A higher score indicates greater impairment.
A negative change score indicates improvement.
