Change From Baseline in HAM-D-24 Total Score After 8 Weeks of Treatment
The Hamilton Depression Scale - 24 Items (HAM-D-24) measures depression severity. Items are rated on a scale from 0 (symptoms not present) to a maximum of 2 to 4 (symptom extremely severe) for a total score range of 0 to 76. The higher the score, the more severe.
Time frame: Baseline and Week 8
Change From Baseline in HAM-D-24 Total Score After 6 Weeks of Treatment
Time frame: Baseline and Week 6
Change From Baseline in HAM-D-24 Total Score After 4 Weeks of Treatment
Time frame: Baseline and Week 4
Change From Baseline in HAM-D-24 Total Score After 2 Weeks of Treatment
Time frame: Baseline and Week 2
Change From Baseline in HAM-D-24 Total Score After 1 Week of Treatment
Time frame: Baseline and Week 1
Change From Baseline in MADRS Total Score After 8 Weeks of Treatment
The Montgomery Åsberg Depression Rating Scale (MADRS) is a depression rating scale consisting of 10 items, each rated 0 (no symptom) to 6 (severe symptom). The 10 items represent the core symptoms of depressive illness. The rating should be based on a clinical interview with the patient, moving from broadly phrased questions about symptoms to more detailed ones, which allow a precise rating of severity, covering the last 7 days. Total score from 0 to 60. The higher the score, the more severe.
Time frame: Baseline and Week 8
Change From Baseline in HAM-A Total Score After 8 Weeks of Treatment
The Hamilton Anxiety Rating Scale (HAM-A) consists of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behaviour at interview, somatic (sensory), cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic, and somatic (muscular) symptoms. Each symptom is rated from 0 (absent) to 4 (maximum severity). Total score from 0 to 56. The higher the score, the more severe.

Change From Baseline in CGI-S Score After 8 Weeks of Treatment
The Clinical Global Impression - Severity of Illness (CGI-S) is a 7-point scale rated from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). The investigator should use his/her total clinical experience with this patient population to judge how mentally ill the patient is at the time of rating.
Time frame: Baseline and Week 8
Change in Clinical Status Using CGI-I Score at Week 8
The Clinical Global Impression - Global Improvement (CGI-I) is a 7-point scale rated from 1 (very much improved) to 7 (very much worse). The investigator rated the patient's overall improvement relative to baseline, whether or not, in the opinion of the investigator, this was entirely due to the drug treatment.
Time frame: Week 8
Change From Baseline in GDS Total Score After 8 Weeks of Treatment
The Geriatric Depression Scale (GDS) is a patient self-rating scale designed for the screening of depression in the elderly. It has also been validated as a measure of depression severity. The original version consists of 30 questions with a yes/no answer. In this study, the short 15-item version was used. The total score ranges from 0 to 15, with 15 representing maximum severity.
Time frame: Baseline and Week 8
Proportion of Responders at Week 8 (Response Defined as a >=50% Reduction in the HAM-D-24 Total Score)
Time frame: Week 8
Proportion of Remitters at Week 8 (Remission Defined as a MADRS Total Score <=10)
Time frame: Week 8
Risk of Suicidality Using C-SSRS Scores
The Columbia-Suicide Severity Rating Scale (C-SSRS) was developed by researchers at Columbia University as a tool to systematically assess suicidal ideation and behaviour in patients during participation in a clinical study. The C-SSRS is composed of questions that address suicidal behaviour and questions that address suicidal ideation, with sub-questions that assess severity. The tool was administered via an interview with the patient.
Time frame: Up to 8 weeks
