Efficacy of Convalescent Plasma Therapy in the Early Care of COVID-19 Patients. — PLASCOSSA  

COVID-19 Clinical Trial

Official title:
Evaluation Of Efficacy Of COVID-19 Convalescent Plasma Versus Standard Plasma In The Early Care Of COVID-19 Patients Hospitalized Outside Intensive Care Units.

Clinical Trial Summary

COVID-19 (Corona Virus Disease 2019) hospitalized patients evolution is marked by the risk of worsening of the respiratory system during the second week of the disease. To date, treatments are currently being evaluated and none of them have shown to be effective in the care of these patients. The use of convalescent plasma is a passive immunotherapy. It has often been used in respiratory virus epidemic situations (during the 1918 or 2009 influenza pandemic, or during SARS-CoV-1 or MERS-CoV pandemic). Effects reported in literature are in favour of a beneficial impact of transfusion of these plasma without serious adverse effects reported. PlasCoSSA is a randomized, controlled, triple-blinded, parallel clinical trial. This study tests the efficacy of convalescent plasma transfusion therapy in the early care of COVID-19 hospitalized patients outside intensive care units.

Clinical Trial Description

During SARS-CoV-2 infection, two clinical-biological phases can be observed: an initial viral phase followed by an immunological phase whose onset has been associated with more severe prognosis. Hospitalized patients with comorbidities or clinical risk factors have a higher risk of respiratory functions deterioration and significant risk to need intensive care. Early transfusion of convalescent plasma (2 units of 200-230 mL of apheresis plasma inactivated by amotosalen) would prevent this secondary worsening and reduce the risk to be transferred to intensive care, length of stay and mortality. Considering clinical and biological manifestations of the disease, including coagulation disorders, endothelial alterations, immunological disorders, it seems interesting to compare this convalescent plasma with a SARS-CoV-2 lacking antibodies plasma. ;
