Brief Summary:
This is a double-blinded, randomized control trial to assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma as early treatment. Participants will be randomized 2:1 to receive either convalescent plasma qualitatively positive for SARS-CoV-2 antibody ("anti-SARS-CoV-2 plasma") or control (albumin 5%). This study will investigate the potential of convalescent plasma (CP) to reduce severity of and/or help treat SARS-CoV-2 disease in patients with mild disease.

Condition or disease Intervention/treatment Phase
SARS-CoV 2 COVID-19 Biological: Convalescent Plasma (anti-SARS-CoV-2 plasma) Biological: Control (albumin 5%) Phase 2

Detailed Description:
There are no approved therapies for Coronavirus disease 2019 (COVID-19), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Exposure to viruses results in an adaptive immune response that commonly include antibodies with neutralization activity. Plasma from subjects who have recovered from viral infections has been used to both prevent or treat disease. Notable examples of the successful use of convalescent plasma (CP) include influenza, measles, Argentine hemorrhagic fever, Middle East respiratory syndrome (MERS), Ebola and severe acute respiratory syndrome (SARS). In recent work in China, an open label safety trial of CP in patients with COVID-19 suggested a substantive benefit.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 150 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: A total of 150 eligible subjects will be randomized in a 2:1 ratio to receive either convalescent plasma qualitatively positive for SARS-CoV-2 antibody (anti-SARS-CoV-2 plasma) or control (albumin 5%)
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 2 Randomized, Double-blinded Trial to Evaluate the Efficacy and Safety of Human Anti-SARS-CoV-2 Plasma for Early Treatment of COVID-19
Actual Study Start Date : March 12, 2021
Estimated Primary Completion Date : April 2022
Estimated Study Completion Date : April 2022

Arm Intervention/treatment
Experimental: Convalescent Plasma (anti-SARS-CoV-2 plasma)
Participants randomized to the experimental arm will receive 2 units (approximately 200 to 250 mL per unit, total 400-500mL) of convalescent plasma that was collected from a volunteer who recovered from COVID-19 disease.
Biological: Convalescent Plasma (anti-SARS-CoV-2 plasma)
Convalescent Plasma that contains antibody titers against SARS-CoV-2.

Active Comparator: Control (albumin 5%)
Participants randomized to the control arm will receive 2 units of 250 mL (500mL total) of albumin (human) 5% infusion. The albumin will be prepared in bags that are identical to the bags used for plasma. The similar appearance of albumin and plasma will facilitate maintaining the blinded status of subjects and most of the study staff.
Biological: Control (albumin 5%)
Albumin (Human) 5% is a sterile aqueous solution for intravenous use containing the albumin component human plasma.

Primary Outcome Measures :
  1. Rate of Severe Disease [ Time Frame: Up to 28 days ]
    The efficacy of treatment will be determined by rating disease severity on Day 28, or last rating evaluated, using a seven-category severity scale.

Secondary Outcome Measures :
  1. Rate of measurable anti-SARS-CoV-2 titers [ Time Frame: Up to 90 days ]
    To compare the rate of measurable anti-SARS-CoV-2 titers between recipients of CP (anti-SARS-CoV-2 plasma) versus control (albumin 5%).

  2. Rate of SARS-CoV-2 PCR Positivity [ Time Frame: Up to 28 days ]
    Compare the rates of SARS-CoV-2 PCR positivity (RT PCR) amongst the anti-SARS-CoV-2 convalescent plasma and control (albumin 5%).

  3. Duration of SARS-CoV-2 PCR Positivity [ Time Frame: Up to 28 days ]
    Compare the duration of SARS-CoV-2 PCR positivity (RT PCR) amongst the anti-SARS-CoV-2 convalescent plasma and control (albumin 5%).

  4. Levels of SARS-CoV-2 RNA [ Time Frame: Up to 28 days ]
    Compare the levels of SARS-CoV-2 RNA between the recipients of antiSARS-CoV-2 plasma and control (albumin 5%)

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Subjects must be 18 years of age or older
  • Recent close contact with a person with COVID-19, i.e. last close contact occurred within 7 days of anticipated infusion of study product. It is anticipated that most contacts will be household contacts with extensive interaction. All must meet the CDC criteria for close contacts. This includes healthcare workers at higher risk of developing severe disease.


  • Recent self-reported or documented evidence of infection by nasal swab PCR that is positive for SARS-CoV-2, i.e., nasal sample was collected within 7 days or 10 days of anticipated infusion of study product for those who are asymptomatic or symptomatic, respectively.
  • Evidence of infection by nasal swab PCR that is positive for SARS-CoV-2 at screening visit.
  • May or may not be hospitalized.
  • No symptoms or no more than 5 days of mild symptoms at the time of screening. Mild symptoms (rated by participant as mild and not interfering with normal daily activities) may include:

    • Mild rhinorrhea
    • Mild sore throat or throat irritation
    • Mild nonproductive cough
    • Mild fatigue (able to perform Activities of Daily Living (ADLs))
  • Risk for severe COVID-19 based on a risk score of ≥ 1 Calculated Risk Score of ≥ 1 point, with risk factors based on Center for Disease Control and Prevention (CDC) description

    • Age 65-74: 1 point
    • Age ≥ 75: 2 points
