NCT05904067

Brief Summary

The study is to evaluate the safety and efficacy of COVID-19 convalescent plasma (CCP) transfusion to prevent COVID-19 in adult recipients following hematopoietic stem cell transplantation. 72 patients will be randomized in a 1:1 ratio to receive either CCR (36 patients) or not (36 patients). Patients in the CCP group will receive 200 ml of CCP at +14 days, +28 days, +2 months, and +3 months following hematopoietic stem cell transplantation. Patients in the control group would be routinely given oral ursodeoxycholic acid for +14 days after transplantation. The primary goal of the study is to evaluate the safety of CCP and the incidence of COVID-19 infection within +28 days after the last infusion of CCP.
