Safety and Efficacy of Convalescent Plasma Transfusion for Patients With COVID-19

This is a multicenter double blinded study to evaluate the efficacy and safety of convalescent plasma from COVID-19 recovered individuals to treat hospitalized patients with severe COVID-19 disease. The study will enroll 410 subjects who will be randomized 1:1 to receive convalescent plasma or normal saline solution in a blinded manner. The primary endpoint will be improvement on the 8 point WHO scale over 28 days. Mortality at day 28 will be a secondary endpoint. An interim analysis will be done when 224 patients have completed their follow up to assess safety and to indicate continuation or stopping of the study, based on safety and efficacy observed.
