Parts A and B: Change From Baseline in the 17-Item Hamilton Rating Scale for Depression (HAM-D) Total Score at Day 15
The 17-item HAM-D is used to rate the severity of depression in participants who are already diagnosed as depressed. 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 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. The HAM-D total score was calculated as the sum of the 17 individual item scores and could range from 0 to 52. Higher scores indicated more severe depression. A negative change from Baseline indicates less depression.
Time frame: Parts A and B: Baseline, Day 15

Time frame: Part B: Days 3, 8, 15, 21 and 45
Parts A and B: Change From Baseline in HAM-D Subscales Scores
HAM-D is used to rate the severity of depression in participants who are already diagnosed as depressed. HAM-D subscales: Core subscale (symptoms-depressed mood, feelings of guilt, suicide, work and activities, and retardation ); Anxiety subscale (symptoms-anxiety \[psychic and somatic\], somatic symptoms \[gastrointestinal and general\], hypochondriasis, loss of weight); Bech-6 subscale (symptoms-depressed mood, feelings of guilt, work and activities, retardation, anxiety psychic, and somatic symptoms general); Meier subscale (symptoms-depressed mood, feelings of guilt, work and activities, retardation, agitation, and anxiety psychic). Each item was scored in a range of 0 to 2 or 0 to 4, higher scores=greater degree of depression. Subscale scores were calculated as the sum of the individual item scores comprising each subscale. Scores were transformed to a scale of 0 to 100, with higher scores indicated more severe depression. A negative change from Baseline indicates less depression.
Time frame: Part B: Baseline, Days 3, 8, 15, 21 and 45
Parts A and B: Change From Baseline in HAM-D Individual Item Scores
The 17-item HAM-D is used to rate the severity of depression in participants who are already diagnosed as depressed. Individual items on the scale were scored in a range of 0 to 2 or 0 to 4. Symptoms scored in a range of 0 to 2: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following symptoms were 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. Higher scores indicated a greater degree of depression. A negative change from Baseline indicates less depression.

Parts A and B: Change From Baseline in Montgomery and Åsberg Depression Rating Scale (MADRS) Total Score
The MADRS is a 10-item questionnaire used to measure the severity of depressive episodes in participants with mood disorders. It includes questions on the following symptoms: apparent sadness; reported sadness; inner tension; reduced sleep; reduced appetite; concentration difficulties; lassitude; inability to feel; pessimistic thoughts; and suicidal thoughts. Each item was scored in a range of 0 (no symptoms) to 6 (symptoms of maximum severity). The MADRS total score was calculated as the sum of the 10 individual item scores and could range from 0 to 60. Higher scores indicated more severe depression. A negative change from Baseline indicates less depression.
Time frame: Part B: Baseline, Days 3, 8, 15, 21 and 45
Parts A and B: Percentage of Participants With Clinical Global Impression - Improvement (CGI-I) Response
The Clinical Global Impression - Improvement (CGI-I) item of the CGI scale uses a 7-point Likert scale to measure the overall improvement in the participant's condition posttreatment. The investigator rated the participant's total improvement whether or not it was due entirely to drug treatment. Response choices included: 0=not assessed, 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, and 7=very much worse. CGI response was defined as a CGI-I score of 1 (very much improved) or 2 (much improved). The percentage of participants with overall improvement in post-treatment condition, rated by investigator as very much improved (CGI-I score of 1) or much improved (CGI-I score of 2) is reported.
Time frame: Part B: Days 3, 8, 15, 21 and 45
Parts A and B: Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score
The 14-item HAM-A was used to rate the severity of symptoms of anxiety. Each of the 14 items was defined by a series of symptoms and measured both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). The individual items were scored in a range of 0 (not present) to 4 (very severe). The HAM-A total score was calculated as the sum of the 14 individual item scores and could range from 0 to 56 where a score of \<17=mild severity; 18-24= mild to moderate severity and 25-30=moderate to severe severity. A negative change from Baseline indicates less anxiety.

Time frame: Part B: Days 3, 8, 15, 21 and 45
Parts A and B: Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE was defined as an AE with an onset that occurs after receiving study drug.
Time frame: Part A: Up to Day 75; Part B: Up to Day 45
Part B: Number of Participants With Potentially Clinically Significant Vital Sign Measurements
Vital signs included assessments of supine and standing systolic blood pressure (SBP), supine and standing diastolic blood pressure (DBP), and heart rate.
Time frame: Part B: From first dose of study drug up to 45 days
Part B: Number of Participants With Potentially Clinically Significant Laboratory Evaluations
Laboratory tests included tests of Hematology, Chemistry, and Urinalysis.
Time frame: Part B: From first dose of study drug up to 45 days
Part B: Change From Baseline in Electrocardiogram (ECG) Parameter Heart Rate
ECG parameters included assessment of the standard 12-lead ECG intervals: QT, QTcF, PR, RR, QRS, and heart rate. Heart rate was measured in terms of beats per minute. Change from Baseline in heart rate at specified time points were reported.

Part B: Number of Participants With a Response of "Yes" to Any Suicidal Ideation or Suicidal Behaviors Item Using the Columbia Suicide Severity Rating Scale (C-SSRS)
C-SSRS was used to assess the suicidality of participants during the study. The assessment included "yes" or "no" responses for 5 questions, each related to suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings were provided for severity of ideation (if present), from 1 to 5, with 5 being the most severe. Number of participants with a response of 'yes' to any suicidal ideation or suicidal behavior item as measured by C-SSRS is reported.
Time frame: Part B: Up to Day 45
