Key clinical point: Critically ill patients with COVID-19 fail to benefit from convalescent plasma.
Major finding: The trial was stopped early after the probability of futility was calculated at 99.4%. Convalescent plasma vs. no plasma groups had 0 vs 3 organ support-free days, 37.3% vs 38.4% in-hospital mortality rates, and 14 vs 14 median days alive and free of organ support.
Study details: The data come from an open-label, randomized component of the ongoing REMAP-CAP trial (n=2,011). Critically ill adults with COVID-19 were randomly assigned to receive convalescent plasma or not.
Disclosures: The study was funded by nonprofits in multiple countries. Several authors reported relationships with pharmaceutical companies and/or research organizations.
