What this trial studies

This study evaluates the safety and efficacy of COVID-19 convalescent plasma (CCP) transfusion in preventing COVID-19 in adult patients who have undergone hematopoietic stem cell transplantation. A total of 72 patients will be randomly assigned to receive either CCP or a control treatment of oral ursodeoxycholic acid. The CCP group will receive 200 ml of plasma at specified intervals following transplantation, while the control group will receive standard care. The primary goal is to assess the safety of CCP and the incidence of COVID-19 infection within 28 days after the last infusion.

Who should consider this trial

Good fit: Ideal candidates are adults aged 16 and older who are receiving hematopoietic stem cell transplantation.

Not a fit: Patients who have had a prior COVID-19 infection or those with certain medical conditions that disqualify them from the study may not benefit.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of COVID-19 in vulnerable patients following stem cell transplantation.

How similar studies have performed: While the use of convalescent plasma has been explored in various contexts, this specific application in stem cell transplant recipients is relatively novel.
