Change From Baseline in the 17-item HAM-D Total Score at Day 15 |
The 17-item HAM-D scale is used to assess the severity of depression. It is comprised of individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia, work and activities, retardation, agitation, anxiety, somatic symptoms, genital symptoms, hypochondriasis, loss of weight, and insight. Individual items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4), with 0=none/absent and 4=most severe. The total HAM-D score is the sum of individual items, ranging from 0 to 52; where a higher score indicates more depression. A negative change indicates improvement. A mixed Model for Repeated Measures (MMRM)was used for the analysis. |

Change From Baseline in the CGI-S Score at Day 15 |
The CGI-S is a 7-point Likert scale to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with participants who have the same diagnosis. A participant is assessed on severity of mental illness at the time of rating as 1=normal, not at all ill; 2=borderline ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; and 7= among the most extremely ill participants. A negative change from baseline indicates improvement. MMRM was used for the analysis. A negative change from baseline indicates improvement. MMRM was used for the analysis. |

Percentage of Participants Achieving HAM-D Response |
The 17-item HAM-D scale is used to assess the severity of depression. It is comprised of individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia, work and activities, retardation, agitation, anxiety, somatic symptoms, genital symptoms, hypochondriasis, loss of weight, and insight. Individual items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4), with 0=none/absent and 4=most severe. The total HAM-D score is the sum of individual items, ranging from 0 to 52; where a higher score indicates more depression. HAM-D response is defined as having a greater than or equal to (=) 50% reduction in HAM-D score from baseline. Generalized Estimating Equation (GEE) method was used for the analysis. |

Percentage of Participants Achieving HAM-D Remission |
The 17-item HAM-D scale is used to assess the severity of depression. It is comprised of individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia, work and activities, retardation, agitation, anxiety, somatic symptoms, genital symptoms, hypochondriasis, loss of weight, and insight. Individual items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4), with 0=none/absent and 4=most severe. The total HAM-D score is the sum of individual items, ranging from 0 to 52; where a higher score indicates more depression. HAM-D remission is defined as HAM-D total score less than or equal to (=) 7. GEE model was used for the analysis. |

Percentage of Participants With Clinical Global Impression - Improvement (CGI-I) Response at Day 15 |
CGI-I response is defined as having a CGI-I score of "very much improved" (score of 1) or "much improved" (score of 2)". The CGI-I employs a 7-point Likert scale to measure the overall improvement in the participant's condition posttreatment. Response choices include 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, and 7=very much worse. GEE model was used for the analysis. |

Change From Baseline in MADRS Total Score at Day 15 |
The MADRS is a 10-item diagnostic questionnaire used to measure the severity of depressive episodes in participants with mood disorders. The MADRS total score was calculated as the sum of the 10 individual item scores and each item yields a score of 0 to 6. The overall MADRS score ranges from 0 to 60 where higher MADRS scores indicate more severe depression. A negative change indicates improvement. MMRM was used analysis. |

Change From Baseline in HAM-A Total Score at Day 15 |
The 14-item HAM-A is comprised of a series of symptoms, and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). The HAM-A total score was calculated as the sum of the 14 individual item scores. The scoring for HAM-A is calculated by assigning scores of 0 (not present) to 4 (very severe) to each item, with a total HAM-A score range of 0 to 56, where <17 indicates mild severity, 18 to 24 indicates mild to moderate severity, and 25 to 30 indicates moderate to severe severity. A negative change from baseline indicates improvement. MMRM was used for the analysis. |

Time to First HAM-D Response |
17-item HAM-D scale is used to assess the severity of depression. It is comprised of individual ratings related to following symptoms: depressed mood, feelings of guilt, suicide, insomnia, work and activities, retardation, agitation, anxiety, somatic symptoms, genital symptoms, hypochondriasis, loss of weight, and insight. Individual items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4), with 0=none/absent and 4=most severe. Total HAM-D score is sum of individual items, ranging from 0 to 52; where higher score indicates more depression. Time to first HAM-D response is defined as time from first administration of the study drug to first time when =50% reduction in HAM-D score from baseline is achieved. |

Change From Baseline in Patient- Reported Outcome (PRO) Measures of Health-Related Quality of Life, as Assessed by the 36-item Short Form Version 2 (SF-36v2) Score at Days 8, 15, 28 and 42 |
Participant's health was assessed using PRO health related quality of life (HRQOL) SF-36 V2. SF-36v2 covers 8 health dimensions, including 4 physical health status domains (physical functioning, role participation with physical health problems [role-physical], bodily pain, and general health) and 4 mental health status domains (vitality, social functioning, role participation with emotional health problems [role-emotional], and mental health). Physical Component Summary and the Mental Component Summary are derived from the 8 domains. Each domain is scored by summing the individual items, scores varying between 0 and 100. Both the domain scores and the component summary scores are norm-based. A higher score indicates a better state of health. Positive change indicates improvement. MMRM was used for the analysis. |

Change From Baseline in PRO Measures of Depressive Symptoms, as Assessed by the 9-item Patient Health Questionnaire (PHQ-9) Total Score at Days 8, 15, 28 and 42 |
The PHQ-9 is a participant-rated depressive symptom severity scale where scoring is based on responses to specific questions. The score was calculated as the sum of the 9 individual item scores. The PHQ-9 total score ranges from 0 to 27 categorized as follows: 1 to 4 = minimal depression, 5 to 9 = mild depression, 10 to 14 = moderate depression, 15 to 19 = moderately severe depression, and 20 to 27 = severe depression with a higher score indicating more depression. A negative change indicates improvements. MMRM was used for analysis. |
