Primary Outcome Measures
NameTimeMethod
Change From Augmentation Baseline for Non-Remitters in Montgomery-Ǻsberg Depression Rating Scale (MADRS) Total Score at Week 6 - Last Observation Carried Forward (LOCF)Augmentation Baseline, 6 weeks

MADRS is a validated, 10-item rating scale with each item being scored on a scale from 0-6 with a total score ranging from 0-60. Lower scores indicate a decreased severity of depression.

Secondary Outcome Measures
NameTimeMethod
Change From Augmentation Baseline for Non-Remitters in the Hamilton Depression Scale (HAM-D) Total Score at Week 6 - LOCFAugmentation Baseline, 6 weeks

The HAM-D is a validated rating scale which consists of 17 items. Nine of the items are scored on a scale of 0-4 and 8 items are scored on a scale of 0-2 for a total scoring range of 0-52. A score of 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates increased severity of depression. In general, the lower the total score the less severe the depression.

Change From Augmentation Baseline for Non-Remitters in the Sheehan Disability Scale (SDS) Total Score at Week 6Augmentation Baseline, 6 weeks

Designed to evaluate the extent to which illness symptoms impact a subject's life in 3 areas: work/school, social, and family/home. Each area is scored on a scale from 0 (no impairment) to 10 (highly impaired) with a total score ranging from 0 (unimpaired) to 30 (highly impaired). Lower scores translate into less impairment.

Percentage of Non-Remitters With Improvement on Clinical Global Impression-Improvement (CGI-I) at Week 6 - LOCF6 weeks

Clinical Global Impression-Improvement (CGI-I) consists of a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved) or 2 (much improved) on the scale.

Assessment in Non-Remitters of Clinical Global Impression-Severity of Illness (CGI-S) at Augmentation BaselineAugmentation baseline

CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)

Assessment in Non-Remitters of Clinical Global Impression-Severity of Illness (CGI-S) at Week 66 weeks

CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)

Change From Augmentation Baseline for Non-Remitters in the Behavior Rating Inventory of Executive Function - Adult Version (BRIEF-A) Scale Total Score at Week 6Augmentation Baseline and 6 weeks

BRIEF-A is a validated 75-item questionnaire composed of three scales (Global Executive Composite, Behavioral Recognition Index, and Metacognition Index). Items are rated 1 (never), 2 (sometimes), and 3 (often). There is no range for a total score. Raw scale scores are used to develop interpretive reports. Lower scores reflect better functioning.

Change From Augmentation Baseline for Non-Remitters in the Multidimensional Assessment of Fatigue (MAF) Scale Total Score at Week 6Augmentation Baseline and 6 weeks

MAF contains 16 items scored on a scale from 1 (not at all) to 10 (a great deal). Answers are converted to a Global Fatigue Index with total scores ranging from 1 (no fatigue) to 50 (severe fatigue). Lower scores indicate less fatigue.

Change From Augmentation Baseline for Non-Remitters in the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) Scale Total Score at Week 6Augmentation Baseline and 6 weeks

QIDS-SR is a validated, self-reported rating scale that contains 16 items scored on a scale from 0-3 with total scores ranging from 0 (no depression) to 27 (very severe depression). Lower scores indicate less depression.

Change From Augmentation Baseline for Remitters in MADRS Total Score at Week 6 - LOCFAugmentation Baseline and 6 weeks

MADRS is a validated, 10-item rating scale with each item being scored on a scale from 0-6 with a total score ranging from 0-60. Lower scores indicate a decreased severity of depression.

Change From Augmentation Baseline for Remitters in the HAM-D Total Score at Week 6 - LOCFAugmentation Baseline and 6 weeks

The HAM-D is a validated rating scale which consists of 17 items. Nine of the items are scored on a scale of 0-4 and 8 items are scored on a scale of 0-2 for a total scoring range of 0-52. A score of 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates increased severity of depression. In general, the lower the total score the less severe the depression.

Change From Augmentation Baseline for Remitters in the SDS Total Score at Week 6Augmentation Baseline and 6 weeks

Designed to evaluate the extent to which illness symptoms impact a subject's life in 3 areas: work/school, social, and family/home. Each area is scored on a scale from 0 (no impairment) to 10 (highly impaired) with a total score ranging from 0 (unimpaired) to 30 (highly impaired). Lower scores translate into less impairment.

Percentage of Remitters With Improvement on CGI-I at Week 6 - LOCF6 weeks

Clinical Global Impression-Improvement (CGI-I) consists of a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved) or 2 (much improved) on the scale.

Assessment in Remitters of CGI-S at Augmentation BaselineAugmentation Baseline

CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)

Assessment in Remitters of CGI-S at Week 66 weeks

CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)

Change From Augmentation Baseline for Remitters in the BRIEF-A Scale Total Score at Week 6Augmentation baseline and 6 weeks

BRIEF-A is a validated 86-item questionnaire composed of three scales (Global Executive Composite, Behavioral Recognition Index, and Metacognition Index). Items are rated 1 (never), 2 (sometimes), and 3 (often). Lower scores reflect better functioning.

Change From Augmentation Baseline for Remitters in the MAF Scale Total Score at Week 6Augmentation baseline and 6 weeks

MAF contains 16 items scored on a scale from 1 (not at all) to 10 (a great deal). Answers are converted to a Global Fatigue Index with total scores ranging from 1 (no fatigue) to 50 (severe fatigue). Lower scores indicate less fatigue.
