| Number of Participants Achieving Clinical Global Impression - Improvement (CGI-I) Response at Day 15 | Day 15 | CGI-I response is defined as a CGI-I score of very much improved or much improved. The CGI-I employs a 7-point Likert scale to measure the overall improvement in the participant's condition post-treatment. The Investigator rated the participant's total improvement whether or not it was due entirely to drug treatment. Response choices included: 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, and 7=very much worse. |
| Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score at Day 15 | Baseline, Day 15 | The 14-item HAM-A is used to rate the severity of symptoms of anxiety. Each of the 14 items is defined by a series of symptoms and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Scoring for HAM-A is calculated by assigning scores of 0 (not present) to 4 (very severe) to each item. Total HAM-A score is calculated as the sum of the 14 individual item scores with a total score range of 0 to 56, where the score of \<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 less severe symptoms. |
| Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score at Day 15 | Baseline, Day 15 | The MADRS is a 10-item diagnostic questionnaire used to measure the severity of depressive episodes in participants with mood disorders. Each item is rated on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). Total MADRS score, calculated as the sum of the 10 individual items, ranges from 0 to 60 with a higher score indicating more depression. A negative change from baseline indicates less severe symptoms. |

The following symptoms are scored in a range of 0 to 4: Agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis. For each symptom, higher scores indicate more severe depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression. |
| Change From Baseline in Insomnia Severity Index (ISI) Total Score | Baseline, Days 15, and 42 | The ISI is a validated questionnaire designed to assess the nature, severity, and impact of insomnia. The ISI uses a 5-point Likert scale to measure various aspects of insomnia severity (0=none, 1=mild, 2=moderate; 3=severe; 4=very severe), satisfaction with current sleep pattern (0=very satisfied, 1=satisfied, 2=moderately satisfied, 3=dissatisfied, 4=very dissatisfied), and various aspects of the impact of insomnia on daily functioning (0=not at all, 1=a little, 2=somewhat, 3=much, 4=very much). The ISI total score is calculated as the sum of the 7 individual item scores and the possible total score range is from 0 to 28, categorized as follows: 0 to 7=no clinically significant insomnia, 8 to 14=subthreshold insomnia, 15 to 21=clinical insomnia (moderate severity), and 22 to 28=clinical insomnia (severe). Higher scores indicate more severity. A negative change from baseline indicates less severe insomnia. |
| Change From Baseline in Core Consensus Sleep Diary Parameters: Sleep Onset Latency (sSL), Wake After Sleep Onset (sWASO), and Total Sleep Time (sTST) | Baseline, Days 15, and 28 | The Core Consensus Sleep Diary collected subjective responses to a series of questions related to participant's daily sleep pattern (i.e., time to bed, time to fall asleep, time to final awakening, and a question related to quality of sleep) to derive sleep parameters, including sSL, sTST, and sWASO. The take-home participant sleep diary assessment was administered using an eDiary solution. The eDiary was captured using either a provisioned smartphone device or a bring-your-own-device solution, depending on the participant's preference. sTST is a derived parameter calculated as: Time of final awakening - (time when tried to sleep + time taken to fall asleep)-time of being awake after sleep onset. Negative change from baseline in sSL and sWASO indicates improvement. Positive change from baseline in sTST indicates improvement. |
| Change From Baseline in Core Consensus Sleep Diary Parameter: Number of Awakenings (sNAW) | Baseline, Days 15, and 28 | The Core Consensus Sleep Diary was used to collect subjective sleep parameter of sNAW. sNAW was calculated from the onset of persistent sleep until lights on. An awakening is defined as at least 2 consecutive epochs of wake. Individual awakenings were separated by at least 1 epoch of Stage N2 (also fairly light, with sudden increases in brain wave frequency known as sleep spindles), N3 (slow wave or deep sleep) or rapid eye movement (REM) sleep. Lower ratings indicate better sleep quality and more refreshing/restorative quality of sleep. |
| Change From Baseline in Clinical Global Impression - Severity (CGI-S) Score at Day 15 | Baseline, Day 15 | The CGI-S uses a 7-point Likert scale to rate the severity of the participant's illness relative to the clinician's past experience with participants who had the same diagnosis. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating as 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; and 7=extremely ill. A higher score indicates extreme illness/more severity. A negative change from baseline indicates less severe illness. |
| Change From Baseline in the 36-item Short Form Survey Version 2 (SF-36v2) Physical and Mental Component Summary Scores | Baseline, Days 15, and 42 | Participant's health was assessed using Patient-reported outcome (PRO) health related quality of life (HRQOL), SF-36v2 which is a 36-item measure of health status. It covers eight health dimensions including four physical health status domains (physical functioning, role participation with physical health problems, bodily pain, and general health) and four mental health status domains (vitality, social functioning, role participation with emotional health problems, and mental health). Two summary scores, physical component summary (PCS), and mental component summary (MCS) were produced by taking a weighted linear combination of the eight individual domains. The score range for PCS and MCS is 0 to 100 (100=highest level of functioning). Higher scores indicate a better state of health. A negative change from baseline indicates deteriorating health. |
| Change From Baseline in the 9-item Patient Health Questionnaire (PHQ-9) Total Score | Baseline, Days 15, and 42 | The PHQ-9 is a participant-rated depressive symptom severity scale to monitor severity over time for newly diagnosed participants or participants in current treatment for depression. Scoring was based on participants' responses to each of the 9 questions, as follows: 0=not at all; 1=several days; 2=more than half the days; and 3=nearly every day. The PHQ-9 total score was calculated as the sum of the 9 individual item scores. The PHQ-9 total score was 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. Higher scores indicate more severe depression. A negative change from baseline indicates reduced depression. |

Outcome results
Change From Baseline in the 17-item HAM-D Total Score at Day 15
The 17-item HAM-D is used to rate the severity of depression in participants who were already diagnosed as depressed. The HAM-D total score comprises a sum of the 17 individual item scores. 8 items scored in a range of 0 to 2 include: Insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following 9 items are scored in a range of 0 to 4: Agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis. Total HAM-D score can range from 0 to 52, and higher scores indicate severe depression. A negative change from baseline indicates less depression.
Time frame: Baseline (BL), Day 15
Population: mFAS included all randomized participants with valid baseline HAM-D and at least 1 post-baseline HAM-D evaluation, with a total HAM-D score of at least 22 at baseline. Here, Overall number of participants analyzed is the number of participants with data available for analyses.

Change From Baseline in Clinical Global Impression - Severity (CGI-S) Score at Day 15
The CGI-S uses a 7-point Likert scale to rate the severity of the participant's illness relative to the clinician's past experience with participants who had the same diagnosis. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating as 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; and 7=extremely ill. A higher score indicates extreme illness/more severity. A negative change from baseline indicates less severe illness.
Time frame: Baseline, Day 15
Population: mFAS included all randomized participants with valid baseline HAM-D and at least 1 post-baseline HAM-D evaluation, with a total HAM-D score of at least 22 at baseline. Here, Overall number of participants analyzed is the number of participants with data available for analyses.

Change From Baseline in Core Consensus Sleep Diary Parameter: Number of Awakenings (sNAW)
The Core Consensus Sleep Diary was used to collect subjective sleep parameter of sNAW. sNAW was calculated from the onset of persistent sleep until lights on. An awakening is defined as at least 2 consecutive epochs of wake. Individual awakenings were separated by at least 1 epoch of Stage N2 (also fairly light, with sudden increases in brain wave frequency known as sleep spindles), N3 (slow wave or deep sleep) or rapid eye movement (REM) sleep. Lower ratings indicate better sleep quality and more refreshing/restorative quality of sleep.

Change From Baseline in Core Consensus Sleep Diary Parameter: Number of Participants With Subjective Sleep Quality (sSQ) Response
The Core Consensus Sleep Diary collected subjective sleep parameters, including sleep quality (sSQ). The take-home participant sleep diary assessment was administered using an eDiary solution. The eDiary was captured using either a provisioned smartphone device or a bring-your-own-device solution, depending on the participant's preference. sSQ is rated on a 5-point Likert scale ranging from 1 (very poor) to 5 (very good). Higher ratings indicate better sleep quality. sSQ response is defined as having a sSQ score of very good or good.

Change From Baseline in Core Consensus Sleep Diary Parameters: Sleep Onset Latency (sSL), Wake After Sleep Onset (sWASO), and Total Sleep Time (sTST)
The Core Consensus Sleep Diary collected subjective responses to a series of questions related to participant's daily sleep pattern (i.e., time to bed, time to fall asleep, time to final awakening, and a question related to quality of sleep) to derive sleep parameters, including sSL, sTST, and sWASO. The take-home participant sleep diary assessment was administered using an eDiary solution. The eDiary was captured using either a provisioned smartphone device or a bring-your-own-device solution, depending on the participant's preference. sTST is a derived parameter calculated as: Time of final awakening - (time when tried to sleep + time taken to fall asleep)-time of being awake after sleep onset. Negative change from baseline in sSL and sWASO indicates improvement. Positive change from baseline in sTST indicates improvement.

Change From Baseline in HAM-D Maier Subscale Score
The 17-item HAM-D is used to rate the severity of depression in participants who were already diagnosed as depressed. HAM-D subscale scores are calculated as the sum of the items comprising each subscale. The Maier subscale score is the sum of the following symptom scores, scored in a range of 0 to 4: Depressed mood, feelings of guilt, work and activities, retardation, agitation, and anxiety psychic. Total HAM-D Maier subscale scores were transformed to a scale of 0 to 100. Higher scores indicate more severe depression. A negative change from baseline indicates less depression.
Time frame: Baseline, Days 15, and 42
Population: mFAS included all randomized participants with valid baseline HAM-D and at least 1 post-baseline HAM-D evaluation, with a total HAM-D score of at least 22 at baseline. Here, Overall number of participants analyzed is the number of participants with data available for analyses.

Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score at Day 15
The 14-item HAM-A is used to rate the severity of symptoms of anxiety. Each of the 14 items is defined by a series of symptoms and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Scoring for HAM-A is calculated by assigning scores of 0 (not present) to 4 (very severe) to each item. Total HAM-A score is calculated as the sum of the 14 individual item scores with a total score range of 0 to 56, where the score of \<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 less severe symptoms.

Change From Baseline in the 36-item Short Form Survey Version 2 (SF-36v2) Physical and Mental Component Summary Scores
Participant's health was assessed using Patient-reported outcome (PRO) health related quality of life (HRQOL), SF-36v2 which is a 36-item measure of health status. It covers eight health dimensions including four physical health status domains (physical functioning, role participation with physical health problems, bodily pain, and general health) and four mental health status domains (vitality, social functioning, role participation with emotional health problems, and mental health). Two summary scores, physical component summary (PCS), and mental component summary (MCS) were produced by taking a weighted linear combination of the eight individual domains. The score range for PCS and MCS is 0 to 100 (100=highest level of functioning). Higher scores indicate a better state of health. A negative change from baseline indicates deteriorating health.

Change From Baseline in the 9-item Patient Health Questionnaire (PHQ-9) Total Score
The PHQ-9 is a participant-rated depressive symptom severity scale to monitor severity over time for newly diagnosed participants or participants in current treatment for depression. Scoring was based on participants' responses to each of the 9 questions, as follows: 0=not at all; 1=several days; 2=more than half the days; and 3=nearly every day. The PHQ-9 total score was calculated as the sum of the 9 individual item scores. The PHQ-9 total score was 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.

Number of Participants Who Experienced at Least One Treatment-emergent Adverse Event (TEAE) and Serious TEAE in Extended FU Period
An adverse event (AE) is any untoward medical occurrence in a participant administered with a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an IP whether or not related to the product. An AE can include any undesirable medical condition, even if no study treatment has been administered. A TEAE is defined as an AE with onset after the start of IP, or any worsening of a pre-existing medical condition/AE with onset after the start of IP and throughout the study. A serious TEAE is defined as a TEAE that at any dose results in death, is immediately life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, or results in a congenital abnormality or birth defect.
Time frame: Extended FU Period: Day 43 to 182
