Official title
A Randomized Open-Label Trial of CONvalenscent Plasma for Hospitalized Adults With Acute COVID-19 Respiratory Illness (CONCOR-1)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
