Change From Baseline to Week 8 in MADRS Total Score
Description
The Montgomery Aasberg Depression Rating Scale (MADRS) is a 10-item rating scale designed to assess the severity of the symptoms in depressive illness and to be sensitive to treatment effects. Items in the scale assess apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Symptoms are rated on a 7-point scale from 0 (no symptoms) to 6 (severe symptoms). Definitions of severity are provided at two-point intervals. The total score of the 10 items ranges from 0 to 60, with higher values indicating worse outcome. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Title
Change From Baseline to Week 8 in CGI-S Score
Description
The Clinical Global Impression - Severity of Illness (CGI-S) scale assesses the clinician's impression of the patient's current state of mental illness. The clinician uses his or her clinical experience of this patient population to rate the severity of the patient's current mental illness on a 7-point scale ranging from 1 (normal - not at all ill) to 7 (among the most extremely ill patients), with higher values indicating worse outcome. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Percentage of MADRS Responders at Week 8
Description
The Montgomery Aasberg Depression Rating Scale (MADRS) is a 10-item rating scale designed to assess the severity of the symptoms in depressive illness and to be sensitive to treatment effects. Items in the scale assess apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Symptoms are rated on a 7-point scale from 0 (no symptoms) to 6 (severe symptoms). Definitions of severity are provided at two-point intervals. The total score of the 10 items ranges from 0 to 60, with higher values indicating worse outcome. Response was defined as a ≥50% decrease in MADRS total score from baseline. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Percentage of MADRS Remitters at Week 8
Description
The Montgomery Aasberg Depression Rating Scale (MADRS) is a 10-item rating scale designed to assess the severity of the symptoms in depressive illness and to be sensitive to treatment effects. Items in the scale assess apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Symptoms are rated on a 7-point scale from 0 (no symptoms) to 6 (severe symptoms). Definitions of severity are provided at two-point intervals. The total score of the 10 items ranges from 0 to 60, with higher values indicating worse outcome. Remission was defined as a MADRS total score ≤10 and a ≥50% decrease in MADRS total score from baseline. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Title
Changes From Baseline to Week 8 on Sleep Quality as Assessed by Actigraphy (ACT) Parameters
Description
The key ACT parameters assessed were the total sleep time (ACT TST), wake-time after sleep onset (ACT WASO), sleep onset latency (ACT SOL), sleep efficiency (ACT SE), and the number of awakenings (ACT NAW). The results for ACT TST, ACT WASO, and ACT SOL are presented separately from ACT SE, and from ACT NAW, due to the different units of measurement involved. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Changes From Baseline to Week 8 on Sleep Efficiency (SE) as Assessed by Actigraphy (ACT)
Description
The key ACT parameters assessed were the total sleep time (ACT TST), sleep efficiency (ACT SE), sleep onset latency (ACT SOL), wake-time after sleep onset (ACT WASO), and the number of awakenings (ACT NAW). The results for ACT TST, ACT SE, ACT WASO, and ACT NAW are presented separately from ACT SOL as the number of patients available for analysis was different. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Title
Change From Baseline to Week 8 in BRIAN Total Score
Description
The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) is a clinician-rated scale designed to assess biological rhythms. The BRIAN consists of 18 items divided in 4 subscales: sleep (5 items), activity (5 items), social (4 items), and eating pattern (4 items). Each item is rated on a scale from 1 (no difficulties) to 4 (serious difficulties). The total score of the 18 items ranges from 18 to 72, with higher values indicating worse outcome. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Title
CGI-I Score at Week 8
Description
The Clinical Global Impression - Global Improvement (CGI-I) assesses the clinician's impression of the patient's improvement (or worsening). The clinician assesses the patient's condition relative to a baseline on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse), with higher values indicating worse outcome. As this was an open-label exploratory study, all outcomes should be considered as exploratory outcomes.

Eligibility Criteria
Inclusion Criteria - at Screening:
The patient has a Major Depressive Episode (MDE) associated to Major Depressive Disorder (MDD), diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR™). The current MDE should be confirmed using the Mini International Neuropsychiatric Interview (MINI).
The patient has an inadequate response to at least one antidepressant treatment (including the treatment the patient is taking at screening) in the current MDE, as documented by self-report as less than a pre-defined response on the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (ATRQ).
The patient has a pre-defined Montgomery Aasberg Depression Rating Scale (MADRS) total score, and a pre-defined Clinical Global Impression - Severity of Illness (CGI-S) score at screening, and has had the current MDE for ≥10 weeks.
The patient is currently treated for the current MDE with an adequate selective serotonin reuptake inhibitor (SSRI) or a serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant treatment for ≥6 weeks, at the same dosage for ≥2 weeks.
The patient has sleep disturbances (difficulty falling asleep and/or difficulty staying asleep and/or problem waking up too early) confirmed by a pre-defined Insomnia Severity Index (ISI) score.
The patient agrees to protocol-defined use of effective contraception.
Entry Criteria to Treatment Period (Baseline Visit):
The patient still fulfils DSM-IV-TR™ criteria for MDE.
The patient received the same SSRI or SNRI antidepressant treatment at adequate dose during the entire lead-in period.
The patient has a pre-defined MADRS total score.
The patient's improvement in the MADRS total score is a pre-defined percentage compared to screening.
The patient has a pre-defined Clinical Global Impression - Global Improvement (CGI-I) score.
The patient has sleep disturbances (difficulty falling asleep and/or difficulty staying asleep and/or problem waking up too early) confirmed by a pre-defined ISI score.
The patient has sleep disturbances confirmed by pre-defined Latency to Persistent Sleep (LPS) and pre-defined Sleep Efficiency (SE).
