Study Endpoints
Primary Endpoints
Severity and numbers of treatment-emergent AEs
From onset of Brexanolone administration until 30-day follow up.

The number and proportion of individuals experiencing any adverse event, any SAE, and any related adverse event overall will be summarized using frequency tables. No formal statistical tests will be conducted, rather the safety will be evaluated from a risk/benefit perspective. Any p-values reported will be for descriptive purposes only.

Change in Heart Rate from onset of Brexanolone administration until discharge from the drug administration session.
An average of 22 hours (From the start of Brexanolone administration on day 1 at 10 am until 7 am on day 2)

The change in heart rate a physiological safety/stress measure are continuous and obtained multiple times after study drug administration which occurs on day 1. This measure will be analyzed using descriptive statistics and graphical summaries including time-specific summary statistics (e.g., box and whisker plots).

Change in Blood Pressure from onset of Brexanolone administration until discharge from the drug administration session.
An average of 22 hours (From the start of Brexanolone administration on day 1 at 10 am until 7 am on day 2)

The change in blood pressure a physiological safety/stress measure are continuous and obtained multiple times after study drug administration which occurs on day 2. This measure will be analyzed using descriptive statistics and graphical summaries including time-specific summary statistics (e.g., box and whisker plots).

Change in Cortisol from onset of Brexanolone administration until discharge from the drug administration session.
FAn average of 22 hours (From the start of Brexanolone administration on day 1 at 10 am until 7 am on day 2)

The change in Cortisol a physiological safety/stress measure are continuous and obtained multiple times after study drug administration which occurs on day 2. This measure will be analyzed using descriptive statistics and graphical summaries including time-specific summary statistics (e.g., box and whisker plots).

Change in percentage of milliliters of alcohol consumed during the 2-hour ad-libitum drinking paradigm between laboratory sessions (stress vs. neutral).
During the 2-hour ad-libitum drinking paradigm between lab sessions (stress Vs Neutral)

A set of dose-response models will be tested response using the Multiple Comparisons Procedure Modifications (MCP-Mod) methodology including change in percentage of milliliters consumed during the 2-hour ad-libitum drinking paradigm within laboratory sessions (stress and neutral) as dependent variable, the treatment as factor (90, 60, 30 and 0 mcg/kg/h), and baseline dependent value. These dose-response models with repeated measures will be used to test the effects of the regimens of 90, 60, and 30 mcg/kg/h doses of brexanolone on alcohol consumption in self-administration.

Change in Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) score from intake until 30-day follow-up
From intake, day 0 through day 37 (30-day follow-up).

Another set of dose-response models will test Multiple Comparisons Procedure Modifications (MCP-Mod) methodology for the 30-day follow-up in PCL-5 score as dependent variable, the treatment as factor (90, 60, 30 and 0 mcg/kg/h), and baseline dependent value. These dose-response models will be used to test the effects of the regimens of 90, 60, 30 and 0 mcg/kg/h doses of brexanolone on PTSD symptoms. Scale PCL-5 is 0-4 with 0 being not at all and 4 being extreme; the higher score is worse outcome

Change in Change in Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) score from intake until end of dosing.
An average of 22 hours (From intake, day 0 through end of infusion on Day 2)

Another set of dose-response models will test Multiple Comparisons Procedure Modifications (MCP-Mod) methodology including change from intake to end of dosing in PCL-5 score as dependent variable, the treatment as factor (90, 60, 30 and 0 mcg/kg/h), and baseline dependent value. The same modeling will be repeated for the 30-day follow-up timepoint. These dose-response models will be used to test the effects of the regimens of 90, 60, 30 and 0 mcg/kg/h doses of brexanolone on PTSD symptoms. Scale PCL-5 is 0-4 with 0 being not at all and 4 being extreme; the higher score is worse outcome
