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
Experimental: Brexanolone
Participants receiving mechanical ventilation as standard of care will receive brexanolone as a single, continuous, intravenous (IV) infusion for 60 hours.
Drug: Brexanolone
Brexanolone, intravenous (IV) infusion.
Other Names:
  • Allopregnanolone
  • Zulresso
  • SAGE-547

Placebo Comparator: Placebo
Participants receiving mechanical ventilation as standard of care will receive matching placebo as a single, continuous, IV infusion for 60 hours.
Drug: Placebo
Placebo, IV infusion.

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; noninvasive positive pressure ventilation or extracorporeal membrane oxygenation (ECMO).

Secondary Outcome Measures :
  1. Number of Participants With at Least One Treatment-Emergent Adverse Event (TEAE) [ Time Frame: Up to Day 28 ]
  2. All-cause Mortality Through Day 28 [ Time Frame: Up to Day 28 ]
