Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Drug: Brexanolone
Administered as IV infusion.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: From first dose of study drug up to end of follow-up period (up to Day 30)
An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered 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 (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A TEAE is defined as an AE with onset on or after the start of study drug infusion, or any worsening of a pre-existing medical condition/AE with onset on or after the start of study drug infusion.
From first dose of study drug up to end of follow-up period (up to Day 30)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Area Under the Concentration-Time Curve (AUC) From Time Zero to 60 Hours (AUC0-60)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
AUC From Time Zero to Infinity (AUCinf)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Maximum (Peak) Plasma Concentration (Cmax)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Time at Maximum (Peak) Plasma Concentration (Tmax)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Steady-State Drug Concentration in the Plasma During Constant-Rate Infusion (Css)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Given that brexanolone is infused to steady-state plasma concentrations, the model-predicted steady-state drug concentration in the plasma during constant-rate infusion value also represents the predicted maximum plasma concentration at the highest infused dose (90 ug/kg/h).
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Average Drug Concentration in Plasma at Steady State During a Dosing Interval (Cavg)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Cavg was evaluated as the time-weighted average plasma concentrations of brexanolone over the interval.
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)

Half-life is the time required for half of the drug to be eliminated from the serum.
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Clearance of Brexanolone (CL/F)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Clearance is defined as the volume of plasma from which a substance is completely removed per unit time.
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Steady-State of Volume of Distribution (Vss)
Time Frame: Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.
Day 1: From 0 hour (pre-infusion) and at 4, 8, 12, 24, 30, 36, 48 hours during the infusion; at 60 hours (end of infusion)
