ListOutcomeTime frameDescription
Primary
Rate of Responders: i.e. Rate of Patients Who do Not Require Use of High-flow Oxygen Invasive or Non-invasive Mechanical Ventilation (IMV and NIV, Respectively) Within 28 Days and Who Are Alive at the End of the 28 Days Period.
28 days
Subjects will be assessed as responders if they did not receive oxygen supplementation through IMV and NIV during the treatment period, and they are alive at the end of the 28-days treatment period. Non responders are subjects who receive oxygen supplementation (through IMV and NIV during the treatment period) and/or who die during the 28-days treatment period. The use of high-flow oxygen being defined as settings of 3 L/min or greater AND with at least one SpO2 measurement \< 92%, with or without O2 supplementation). Descriptive statistics will be presented by treatment arm.
SecondaryRate of Patients Hospitalized28 days
To evaluate the proportion of patients requiring hospitalization during the study compared to the {Standard of Care + placebo} group An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Efficacy results are only available for the 305 patients randomized at the time of the interim analysis.
SecondaryPercentage of Patients Reporting Each Severity Rating on a 7-point Ordinal Scale28-day treatment period
7-point ordinal scale is defined as Not hospitalized, no limitations on activities; Not hospitalized, limitation on activities; Hospitalized, not requiring supplemental oxygen; Hospitalized, requiring supplemental oxygen; Hospitalized, on non-invasive ventilation or high flow oxygen devices; Hospitalized, on invasive mechanical ventilation or ECMO; Death An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.

As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.
SecondaryRate of Patients Requiring Oxygen Supplementation28-day treatment period
An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.
SecondaryTime to Hospitalization28-day treatment period
An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.
SecondaryTime to Assisted Ventilation and Oxygen Supplementation28-day treatment period
An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.
SecondaryChange From Baseline in microRNA-124 Levelsat each study visit during the 28-day treatment period
An interim analysis was triggered when the first 305 patients were randomized in the study. As the study was stopped for futility based on the interim analysis results, no efficacy data were collected for the patients who were randomized but not included in the interim analysis. Only key outcome analysis was performed during this interim analysis. After discontinuation of the study for futility, Abivax decided to not perform the analysis on this secondary outcome (SAP was amended accordingly). Therefore, these data are not available.
SecondaryChange From Baseline in CRP, Troponin I & T and D-dimerat each study visit during the 28-day treatment period
An interim analysis was triggered when the first 305 patients were randomized in the study.
