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).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Efficacy of Treatment at Day 28 as Assessed by Number of Participants Who Develop SARS-Cov-2 Infection [ 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 as Assessed by Number of Participants With "Serious Adverse Events" [ Time Frame: Up to Day 28 ]
    Number of participants with serious adverse events categorized as either severe infusion reactions or Acute Respiratory Distress Syndrome during the study period.

  3. Safety of Treatment With High-titer Anti- SARS-CoV-2 Plasma Versus Control as Assessed by Cumulative Incidence of Grade 3 and 4 Adverse Events [ Time Frame: Up to Day 28 ]
    Cumulative incidence of grade 3 and 4 adverse events during the study period evaluated as events per 100 person-years will be used to assess safety of the intervention.


Secondary Outcome Measures :
  1. Number of Participants With Severe Disease [ Time Frame: Up to 28 days ]

    Number of participants with severe disease between the anti-SARS-CoV-2 convalescent plasma and control groups. Severity of disease will be measured using the number of participants with any of the disease severity categories below:

    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
