Brief Summary:
Evaluate the efficacy of treatment with high-titer Anti- SARS-CoV-2 plasma versus control (SARS-CoV-2 non-immune plasma) in subjects exposed to Coronavirus disease (COVID-19) at day 28.

Condition or disease Intervention/treatment Phase
Coronavirus Convalescence Biological: Anti- SARS-CoV-2 Plasma Biological: SARS-CoV-2 non-immune Plasma Phase 2

Detailed Description:
This randomized, controlled, double-blinded phase 2 trial will assess the efficacy and safety of Anti- SARS-CoV-2 convalescent plasma as prophylaxis following exposure to COVID-19 (as defined in the inclusion criteria). Adults 18 years of age and older with high risk exposure as defined by CDC may participate. A total of 500 eligible subjects will be randomized in a 1:1 ratio to receive either high titer anti-SARS-CoV-2 plasma or control (SARS-CoV-2 non-immune plasma).

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




Primary Outcome Measures :
  1. 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.

  2. 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.

  3. 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


Secondary Outcome Measures :
  1. 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):

    1. Death
    2. Requiring mechanical ventilation and/or in ICU
    3. non-ICU hospitalization, requiring supplemental oxygen;
    4. non-ICU hospitalization, not requiring supplemental oxygen;
    5. Not hospitalized, but with clinical and laboratory evidence of COVID-19 infection


Other Outcome Measures:
  1. 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).

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.
