There is currently no treatment available for COVID-19, the acute respiratory illness caused by the novel SAR-CoV-2. Convalescent plasma from patients who have recovered from COVID-19 that contains antibodies to the virus is a potential therapy. On March 25th, 2020, the FDA approved the use of convalescent plasma under the emergency investigational new drug (eIND) category. Randomized trials are needed to determine the efficacy and safety of COVID-19 convalescent plasma for acute COVID-19 infection.
The objective of the CONCOR-1 trial is to determine the efficacy of transfusion of COVID-19 convalescent plasma to adult patients admitted to hospital with COVID-19 infection at decreasing the frequency of in-hospital mortality in patients hospitalized for COVID-19.
It is hypothesized that treating hospitalized COVID-19 patients with convalescent plasma early in their clinical course will reduce the risk of death, and that other outcomes will be improved including risk of intubation, and length of ICU and hospital stay.
This pan-Canadian clinical trial has the potential to improve patient outcomes and reduce the burden on health care resources including reducing the need for ICU beds and ventilators.

Experimental: Convalescent plasma
~500 mL ABO compatible convalescent apheresis plasma
Biological: Convalescent plasma
Patients will receive 500 mL of convalescent plasma (from one single-donor unit of 500 mL or 2 units of 250 mL from 1-2 donations) collected by apheresis from donors who have recovered from COVID-19 and frozen (1 year expiration date from date of collection). The plasma unit will be thawed as per standard blood bank procedures and infused into the patient slowly over 4 hours. When administering 2 units of 250 mL, the 2nd unit will be administered after the first, and no longer than 12 hours later. The patient will be monitored for adverse events as per each site's policies.
