Efficacy of CONvalescent Plasma in Patients With COVID-19 Treated With Mechanical Ventilation

Summary

The principal objective of the CONFIDENT trial is to assess the efficacy of two units (400-500 mL in total) of convalescent plasma, as compared to Standard of Care (SoC), to reduce day-28 mortality in patients with SARS-CoV-2 pneumonia who require mechanical ventilation.
