Arm | Intervention/treatment |
---|---|
Experimental: High titer anti-SARS-CoV-2 plasma
Participants with High titer anti-SARS-CoV-2 plasma.
|
Biological: Anti- SARS-CoV-2 Plasma
SARS-CoV-2 convalescent plasma (1 unit; ~200-250 mL collected by pheresis from a volunteer who recovered from COVID-19 disease and has SARS-CoV-2 antibody titers ≥ 1:320 |
Active Comparator: SARS-CoV-2 non-immune plasma
Participants with SARS-CoV-2 non-immune plasma.
|
Biological: SARS-CoV-2 non-immune Plasma
Normal human plasma collected prior to December 2019 |
- Efficacy of treatment at Day 28 [ Time Frame: Day 28 ]Comparison of proportions of cumulative incidence of development of SARS-Cov-2 infection (symptoms compatible with infection and/or + molecular testing) regardless of disease severity, following high-titer Anti- SARS-CoV-2 plasma versus control (SARS-CoV-2 non-immune plasma) in subjects exposed to COVID-19.
- Safety of treatment with high-titer Anti- SARS-CoV-2 plasma versus control - 1 [ Time Frame: Up to Day 28 ]Cumulative incidence of serious adverse events categorized separately as either severe infusion reactions and Acute Respiratory Distress Syndrome during the study period.
- Safety of treatment with high-titer Anti- SARS-CoV-2 plasma versus control - 2 [ Time Frame: Up to Day 28 ]Cumulative incidence of grade 3 and 4 adverse events during the study period
- Cumulative incidence of disease severity [ Time Frame: up to Day 28 ]
Cumulative incidence of disease severity between the anti-SARS-CoV-2 convalescent plasma and control groups after individuals develop SARS-CoV-2 infection. Severity of disease will be measured using a clinical event scale of disease severity (evaluated up to Day 28):
- Death
- Requiring mechanical ventilation and/or in ICU
- non-ICU hospitalization, requiring supplemental oxygen;
- non-ICU hospitalization, not requiring supplemental oxygen;
- Not hospitalized, but with clinical and laboratory evidence of COVID-19 infection
- Anti-SARS-CoV-2 titers Day 0 [ Time Frame: Day 0 ]Compare the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups' anti-SARS-CoV-2 titers at day -1 or day 0 (baseline).
- Anti-SARS-CoV-2 titers Day 1 [ Time Frame: Day 1 ]Compare the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups' anti-SARS-CoV-2 titers at day 1.
- Anti-SARS-CoV-2 titers Day 7 [ Time Frame: Day 7 ]Compare the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups' anti-SARS-CoV-2 titers at day 7.
- Anti-SARS-CoV-2 titers Day 14 [ Time Frame: Day 14 ]Compare the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups' anti-SARS-CoV-2 titers at day 14.
- Anti-SARS-CoV-2 titers Day 90 [ Time Frame: Day 90 ]Compare the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups' anti-SARS-CoV-2 titers at day 90.
- Rates of SARS-CoV-2 PCR positivity [ Time Frame: Up to day 28 ]Compare the rates of SARS-CoV-2 PCR positivity (RT-PCR) amongst the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups at days 0, 7, 14 and 28.
- Duration of SARS-CoV-2 PCR positivity [ Time Frame: Up to day 28 ]Compare the duration (days) of SARS-CoV-2 PCR positivity (RT-PCR) amongst the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups at days 0, 7, 14 and 28.
- Peak quantity levels of SARS-CoV-2 RNA [ Time Frame: Up to day 28 ]Compare the peak quantity levels of SARS-CoV-2 RNA amongst the anti-SARS-CoV-2 convalescent plasma and control (SARS-CoV-2 non-immune plasma) groups at days 0, 1, 7, 14 and 28 days.
