- Primary Outcome Measures
Name Time Method PK of Brexanolone: Area Under the Concentration-time Curve From Time 0 to Last Measurable Concentration (AUC0-last) Day 1- Day 45 Number of Participants With Adverse Events (AEs) According to Severity From the first dose of study drug up to Day 45 Severity will be assessed according to the following scale: Mild, moderate and severe.
Number of Participants With Change From Baseline in Clinically Significant Vital Sign Parameters Baseline up to Day 45 Number of Participants With Abnormal Electrocardiogram (ECG) Parameters From the first dose of study drug up to Day 45 Number of Participants With Change From Baseline in Clinically Significant Clinical Laboratory Evaluations From the first dose of study drug up to Day 45 Change From Baseline in Glasgow Coma Scale (GCS) Score Baseline up to Day 45 The GCS is a simple measure of the depth and duration of impaired consciousness and coma. 3 domains of alertness will be evaluated: eye opening response (scored 1 \[None\] to 4 \[Spontaneous\]), verbal response (scored 1 \[None\] to 5 \[Oriented\]), and motor response (scored 1 \[None\] to 6 \[Obeys commands\]). Total scores range from 3 to 15, with 15 reflecting full alertness.
PK of Brexanolone: Maximum Observed Plasma Concentration (Cmax) Day 1- Day 45 PK of Brexanolone: Apparent Clearance (CL/F) Day 1- Day 45 Number of Participants With Columbia-Suicide Severity Rating Scale (C-SSRS) Responses Baseline up to Day 45 The suicidal ideation and behavior will be monitored during the study using the C-SSRS. This scale consists of a "Baseline/Screening" version that assesses the lifetime and recent experience of the participant with suicidal ideation and behavior, and a "Since Last Visit" version that focuses on suicidality since the last study visit. The C-SSRS includes "yes" or "no" responses for assessment of suicidal ideation and behavior as well as numeric ratings for severity of ideation, if present (from 1 to 5, with 5 being the most severe).
PK of Brexanolone: Time to Reach Cmax (Tmax) Day 1- Day 45 Change From Baseline in Stanford Sleepiness Scale (SSS) Score Baseline up to Day 45 The SSS is a participant-rated measure of sleepiness, frequently used for both research and clinical purposes. The SSS evaluates sleepiness at specific moments in time. Respondents rate their current degree of sleepiness and alertness on a scale of 1 to 7, where the lowest score of '1' indicates the respondent is 'feeling active, vital, alert, or wide awake' and the highest score of '7' indicates the respondent is 'no longer fighting sleep, sleep onset soon; having dream-like thoughts'.
PK of Brexanolone: Volume of Distribution (Vz/F) Day 1- Day 45 Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) From the first dose of study drug up to Day 45 PK of Brexanolone: Area Under the Concentration-time Curve From Time 0 to Infinity (AUC0-inf) Day 1- Day 45 PK of Brexanolone: Apparent Terminal Elimination Half-life (t½) Day 1- Day 45
- Secondary Outcome Measures
Name Time Method Number of Participants With HAM-D Response Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 Response is defined as \>=50 percent (%) reduction from baseline in HAM-D total score. The HAM-D is a 17-item scale used to rate the severity of depression in participants who are already diagnosed as depressed. The total scores of HAM-D range from 0-52. Higher score indicates more depression.
Change From Baseline in Hamilton Depression Rating Scale (HAM-D) Total Score Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The 17-item HAM-D will be used to rate the severity of depression in participants who are already diagnosed as depressed. The 17-item HAM-D is comprised of individual ratings related to the following symptoms: depressed mood (sadness, hopeless, helpless, and worthless), feelings of guilt, suicide, insomnia (early, middle, and late), work and activities, retardation (slowness of thought and speech, impaired ability to concentrate, and decreased motor activity), agitation, anxiety (psychic and somatic), somatic symptoms (gastrointestinal and general), genital symptoms, hypochondriasis, loss of weight, and insight. The total scores range from 0-52. Higher score indicates more depression.
Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The 14-item HAM-A will be 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 the HAM-A is calculated by assigning scores of 0 (not present) to 4 (very severe), with a total score range of 0 to 56, where less than (\<) 17 indicates mild severity, 18 to 24 mild to moderate severity, and 25 to 30 moderate to severe severity. The HAM-A total score will be calculated as the sum of the 14 individual item scores.
Number of Participants With Clinical Global Impression - Improvement (CGI-I) Response Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The CGI-I item employs a 7-point Likert scale to measure the overall improvement in the participant's condition posttreatment. The clinician will rate the participant's total improvement, whether or not it is due entirely to investigational product treatment. Response choices include: 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-I response will be defined as having a CGI-I score of "very much improved" or "much improved."
Change From Baseline in Clinical Global Impression - Severity (CGI-S) Response Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The CGI-S item uses a 7- point Likert scale to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating. Choices include: 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.
Change From Baseline in HAM-D Bech-6 Subscale Score Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The HAM-D Bech 6 subscale score is calculated as the sum of the following six items: Item # 1 (depressed mood), Item # 2 (feelings of guilt), Item # 7 (work and activities), Item # 8 (retardation), Item # 10 (anxiety psychic), and Item # 13 (general somatic symptoms). Each item is scored in a range of 0 to 2 or 0 to 4, with higher scores indicating a greater degree of depression. The scores will be transformed to a 100-point scale with a higher score indicating a greater degree of depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression.
Number of Participants With HAM-D Remission Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 Remission is defined as \<=7.0 HAM-D total score. The HAM-D is a 17-item scale used to rate the severity of depression in participants who are already diagnosed as depressed. The total scores of HAM-D range from 0-52. Higher score indicates more depression.
Change From Baseline in HAM-D Individual Item Score Baseline and at Days 2, 3, 4, 8, 15, 30, and 45 The HAM-D comprises individual ratings of the following 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 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. Higher scores indicate a greater degree of depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression.
