Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPhase II: Relative Change From Baseline in Oxygenation Index in Supine Position at Day 5 (FAS)Baseline and Day 5Relative change (%) from baseline in Oxygenation Index (OI; partial pressure of oxygen in the arterial blood (PaO2) / fractional inspired oxygen (FiO2)) in supine position for ≥2 hours at day 5 (FAS)
PrimaryPhase III: 28-day All-cause Mortality (FAS)Day 28Number and percentage of deaths (all-cause) until Day 28 (FAS)
SecondaryPhase II: All-cause 28-day Mortality (FAS)Day 28Number and percentage of deaths (all-cause) until Day 28 (FAS)
SecondaryPhase II: Early Response at Day 7 After EnrollmentDay 7Number of patients (%) achieving an early response at day 7 after enrollment (FAS)
SecondaryPhase II: Late Response Until Day 28 After EnrollmentBaseline until Day 28Number of patients (%) reaching a late response until day 28 (FAS)
SecondaryPhase II: Relative Change From Baseline in Oxygenation Index in Supine Position (FAS)Baseline, Day 3, Day 7, Day 9, Day 11, Day 15Relative change (%) from baseline in Oxygenation Index (OI) in supine position for ≥2 hours at days 3, 7, 9, 11, and 15 (FAS)
SecondaryPhase III: 60-day All-cause Mortality (FAS)Day 60Number and percentage of deaths (all-cause) until Day 60 (FAS)
SecondaryPhase III: Percentage of Patients With an Improvement in the 8-point Ordinal Scale (FAS)Day 15, Day 28
Percentage of patients with an improvement in the 8-point ordinal scale (Day 15, Day 28), the scale ranges from 0 = 'No clinical or virological evidence of infection' to 8 = 'Death' with higher scores meaning greater limitation and ventilation/organ support
SecondaryPhase III: Percentage of Patients Developing Acute Kidney Failure Until Day 28 (FAS)Day 28
Percentage of patients developing acute kidney failure (estimated glomerular filtration rate \[eGFR\] \< 15 mL/min/1.73m², assessed by the Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\] equation requiring race information) until Day 28 (FAS)
SecondaryPhase III: Percentage of Patients Free of Any Renal Replacement Therapy Within 28 Days Upon Randomization (FAS)Day 28
Percentage of patients free of any renal replacement therapy (RRT) within 28 days upon randomization (FAS), number of patients free of any RRT = number of patients - number of patients with RRT initiated after randomization until Day 28
