The purpose of this study is to test the safety and efficacy of convalescent donor plasma to treat COVID-19 in hospitalized adults in a randomized, placebo-controlled setting. The effect of convalescent plasma will be compared to placebo on clinical outcomes, measured using the COVID Ordinal Outcomes Scale at Day 15, among adults with COVID-19 requiring hospitalization.

Study Design

Phase 3
Study Type
Intervention Model
Parallel Assignment
Intervention Model Description
Eligible participants will be randomized 1:1 to convalescent plasma versus lactated Ringer's solution with multivitamins. Randomization will be completed in permuted blocks and stratified by site, gender, and age. Participants, treating clinicians and outcomes assessors will all be blinded to study group assignment. Study personnel will not be blinded to the study group assignment.
Primary Purpose
Triple (Participant, Care Provider, Outcomes Assessor)

Arm Groups

ArmDescriptionAssigned Intervention
pathogen reduced SARS-CoV-2 convalescent plasma
Transfusion of convalescent plasma will be administered by clinical or research personnel while the participant is hospitalized on Study Day 0. Plasma will be administered at a rate of 500 mL/hour and will be administered within 12 hours of randomization.
  • Biological: pathogen reduced SARS-CoV-2 convalescent plasma
    Convalescent COVID-19 donor plasma is the liquid part of blood that is collected from patients who have recovered from COVID-19 infection. This plasma contains SARS-CoV-2 specific antibodies that may help fight the infection.
Placebo Comparator
Participants randomized to the control group will receive 250mL of Lactate Ringers containing multivitamins intravenously on Day 1 as a placebo.
  • Biological: Placebo
    Lactated Ringer's solution with multivitamins

Detailed Description

After being informed about the study and potential risks, participants confirmed to meet all eligibility criteria who have provided informed consent will be randomized 1:1 to convalescent plasma versus placebo. Transfusion of convalescent plasma or placebo will be administered by clinical or research personnel while the patient is hospitalized on Study Day 0. On Study Days 1-7, participants will be monitored for adverse reactions to the transfusion. Research personnel will also assess patients at Day 14 and Day 28; these assessments will be completed by phone if the participant has been discharged from the hospital.
