Condition or disease | Intervention/treatment | Phase |
---|---|---|
COVID-19 Coronavirus SARS-CoV-2 | Biological: pathogen reduced SARS-CoV-2 convalescent plasma Biological: Placebo | Phase 3 |
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 974 participants |
Allocation: | Randomized |
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. |

Arm | Intervention/treatment |
---|---|
Experimental: 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: Placebo
Participants randomized to the control group will receive 250mL of Lactate Ringers containing multivitamins intravenously on Day 1 as a placebo.

Biological: Placebo
