E.5 End points |
E.5.1 | Primary end point(s) |
Phase II: The primary endpoint in Phase II was the relative change (%) from baseline (day 1 prior to study drug administration at ± 1h of randomization) in Oxygenation Index (PaO2 / FiO2) in supine position at day 5.
Phase III: Based on the preliminary interim analysis of efficacy data from Phase II, the primary endpoint chosen for Phase III is 28-day all-cause mortality.
