Passive Immunotherapy In Patients With SARS CoV-2

Summary

Plasma from convalescent individuals (convalescent plasma, CP) has been used for more than a hundred years for the treatment of infectious diseases. Among patients with COVID-19, it has been used first, in patients with severe infection. Although it is a safe treatment, it has not been possible to demonstrate a reduction in mortality in cases of acute respiratory distress syndrome. The objective of the clinical trial is to evaluate the efficacy and safety of the early use (less than 5 days of symptoms) of CP in patients infected with SARS-CoV-2 with risk factors for severe disease. The primary efficacy endpoint was the proportion of patients requiring oxygen therapy to maintain saturation \>93% on day 14. Secondary objectives included, evaluation of the safety of the treatment, measured as the appearance of some adverse event related to the CP infusion; the evolution of COVID-19 symptoms and WHO progression scale status at day 14 and 28 after inclusion; the need for hospitalization due to progression of COVID-19. COVID-19 progression was considered as worsening of respiratory symptoms requiring oxygen therapy at some point. Finally, death from any cause was evaluated at 28 days, after inclusion in the study.
