Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this study is to evaluate the safety and effectiveness of Coronavirus-90 (COVID-19) convalescent plasma for the treatment of COVID-19. Plasma is the liquid part of blood that is left when all the blood cells have been removed. Convalescent means it is taken from people who were infected with COVID-19 and recovered. The use of this blood product to treat COVID-19 is investigational, which means the U.S. Food and Drug Administration has not yet approved it to be sold commercially. This is a human blood product collected by licensed blood banks. Donors of COVID-19 convalescent plasma must meet all standard blood donor criteria and must also meet all criteria set by the FDA for being a donor of COVID-19 convalescent plasma. A total of 500 patients will take part in the study at 8 hospitals within Beaumont. Similar studies are being done at other centers, but they are not directly related to this study. Participants will be assigned to a study group depending on how sick they are. * Group A: Those who require more than 6 liters (L) of supplemental oxygen but are not on a ventilator * Group B: Those who require a ventilator to preserve their life. Both groups will receive one unit (approximately 200ml or just under 1 cup) of COVID convalescent plasma. The transfusion will be given over about 30 minutes via an IV. Blood samples will be taken prior to and one hour after the transfusion to measure participant antibodies against Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) and a nasopharyngeal swab (deep in the nostril) will be taken to test for presence of the SARS-CoV-2 virus. One hour after the transfusion a blood sample will be taken to measure antibody levels to determine if the plasma caused the antibody level to rise. Similarly, blood samples will be taken to measure antibodies against SARS-CoV-2 and a nasopharyngeal swab will be taken to test for presence of the SARS-CoV-2 virus 1, 3 and every 7 days after the transfusion while the participant is in the hospital The participant's final health status will be determined on day 28. Hospital records will be monitored for 90 days after discharge to determine if the participant is readmitted to the hospital.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
