- Percentage of Participants With At-least a 2-Point Improvement in Ordinal Scale [ Time Frame: Baseline up to Day 14 ]Ordinal Scale 2-Point improvement was defined as percentage of participants with at least a 2-points improvement (increase from baseline) by Day 14. Baseline score was defined as the last score measured before first dosing. The 8-point ordinal scale ranges from 1 to 8: where 1= death, 2= hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3= hospitalized, on non-invasive ventilation or high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (coronavirus disease 2019 [COVID-19] related or otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7= not hospitalized, limitation on activities and/or requiring home oxygen; 8= not hospitalized, no limitations on activities.
- Percentage of Participants With at Least a 2-Point Improvement in the Ordinal Scale up to Day 7 [ Time Frame: Baseline up to Day 7 ]Ordinal Scale 2-points improvement was defined as percentage of participants with at least a 2-points improvement (increase from baseline) by Day 7. Baseline score was defined as the last score measured before first dosing. The 8-point ordinal scale ranges from 1 to 8: where, 1= death, 2= hospitalized, on invasive mechanical ventilation or ECMO; 3= hospitalized, on non-invasive ventilation or high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7= not hospitalized, limitation on activities and/or requiring home oxygen; 8= not hospitalized, no limitations on activities.
- Percentage of Participants With at Least a 1-Point Improvement in the Ordinal Scale [ Time Frame: Baseline up to Day 7 and 14 ]Ordinal Scale 1-point improvement was defined as percentage of participants with at least 1-point improvement (increase from baseline) by Day 7 and 14. Baseline score was defined as the last score measured before first dosing. The 8-point ordinal scale ranges from 1 to 8: where 1= death, 2= hospitalized, on invasive mechanical ventilation or ECMO; 3= hospitalized, on non-invasive ventilation or high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7= not hospitalized, limitation on activities and/or requiring home oxygen; 8= not hospitalized, no limitations on activities.
- Time to Clinical Improvement of 2-points Using Ordinal Scale (TTCI-2) [ Time Frame: Baseline up to Day 28 ]TTCI-2 was defined as the time from randomization to an improvement of 2-points using 8-points Ordinal Scale. The 8-point ordinal scale ranges from 1 to 8: where 1= death, 2= hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3= hospitalized, on non-invasive ventilation or high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (coronavirus disease 2019 [COVID-19] related or otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7= not hospitalized, limitation on activities and/or requiring home oxygen; 8= not hospitalized, no limitations on activities.
- Overall Death Rate [ Time Frame: Baseline up to Day 28 ]Overall death rate was defined as the percentage of participants who died on or before Day 28.
- Rate of Mechanical Ventilation (RMV) [ Time Frame: Baseline up to Day 28 ]The rate of RMV was defined as the percentage of participants who ever used invasive mechanical ventilation or ECMO during the hospital stay.
- Rate of Intensive Care Unit (ICU) Admission [ Time Frame: Baseline up to Day 28 ]The rate of ICU admission was defined as the percentage of participants with ICU admissions.
- Length of Hospitalization [ Time Frame: Baseline up to Day 67 ]Length of hospitalization (days) was defined as (first hospital discharge date - date of randomization + 1).
- Change From Baseline in C-reactive Protein (CRP) Levels [ Time Frame: Baseline, Day 3, 5, 8, 12, 15, 19, 22 and 26 ]The anti-inflammatory and immune effects of selinexor were assessed by CRP levels. Baseline was defined as the most recent non-missing measurement prior to the first administration of study treatment. Change from Baseline at the indicated time points was calculated as the value at the indicated time points minus the value at Baseline.
- Change From Baseline in Ferritin Levels [ Time Frame: Baseline, Day 3, 5, 8, 12, 15, 19, 22 and 26 ]The anti-inflammatory and immune effects of selinexor were assessed by ferritin levels. Baseline was defined as the most recent non-missing measurement prior to the first administration of study treatment. Change from Baseline at the indicated time points was calculated as the value at the indicated time points minus the value at Baseline.
- Change From Baseline in Lactate Dehydrogenase (LDH) Levels [ Time Frame: Baseline, Day 3, 5, 8, 12, 15, 19, 22 and 26 ]The anti-inflammatory and immune effects of selinexor were assessed by LDH levels. Baseline was defined as the most recent non-missing measurement prior to the first administration of study treatment. Change from Baseline at the indicated time points was calculated as the value at the indicated time points minus the value at Baseline.
- Changes From Baseline in Blood Plasma Cytokines Levels-Interleukin-6 (IL-6) [ Time Frame: Baseline, Day 3, 5, 8, 12, 15, 22 and 26 ]The anti-inflammatory and immune effects of selinexor were assessed by blood plasma cytokines like IL-6. Baseline was defined as the most recent non-missing measurement prior to the first administration of study treatment. Change from Baseline at the indicated time points was calculated as the value at the indicated time points minus the value at Baseline.
- Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious TEAEs [ Time Frame: From start of study drug administration up to Day 58 ]Adverse events are defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. Serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAEs are defined as those AEs that develop or worsen after the first dose of study drug. TEAEs included both Serious and non-serious TEAEs.
