Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 29 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Study of Brexanolone for Acute Respiratory Distress Syndrome Due to COVID-19
Actual Study Start Date : December 18, 2020
Actual Primary Completion Date : July 1, 2021
Actual Study Completion Date : July 1, 2021

Arm Intervention/treatment
Placebo Comparator: Placebo
Participants receiving mechanical ventilation as standard of care were randomized to receive a 60-hour single continuous intravenous (IV) infusion of brexanolone-matching placebo.
Drug: Placebo
Administered as IV infusion.

Experimental: Brexanolone
Participants receiving mechanical ventilation as standard of care were randomized to receive a 60-hour single continuous IV infusion of brexanolone at 70 micrograms per kilogram per hour (mcg/kg/h) for 58 hours followed by a 2-hour taper of brexanolone at 35 mcg/kg/h.
Drug: Brexanolone
Administered as IV infusion.

  • Allopregnanolone
  • Zulresso

Primary Outcome Measures :
  1. Percentage of Participants Who Are Alive and Free of Respiratory Failure at Day 28 [ Time Frame: Day 28 ]
    Respiratory failure is defined based on resource utilization, requiring at least one of the following: Endotracheal intubation and mechanical ventilation, oxygen delivered by high-flow nasal cannula (heated, humidified oxygen delivered via reinforced nasal cannula at flow rates >20 liter/minute with fraction of delivered oxygen >=0.5), noninvasive positive pressure ventilation, and extracorporeal membrane oxygenation (ECMO). Percentage of participants who were alive and free of respiratory failure at Day 28 were reported in this outcome measure.

Secondary Outcome Measures :
  1. Number of Participants With at Least One Treatment-Emergent Adverse Event (TEAE) [ Time Frame: From first dose of investigational product up to end of study (up to Day 40) ]
    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.

  2. Number of Participants Who Died Through Day 28 [ Time Frame: From screening up to Day 28 ]
    All cause mortality was reported up to Day 28 in this outcome measure.

Inclusion Criteria:

  • Participant was confirmed positive for the novel coronavirus responsible for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection as determined by polymerase chain reaction (PCR) at Screening
