The median age was 60.5 years (interquartile range [IQR], 48–68), 58.1% were men and the median time from symptom onset to randomisation was 10 days (IQR, 8–12). Neutralising antibodies titres >1:80 were present in 133 (83.1%) patients at baseline. The proportion of patients with clinical improvement on day 28 was 61.3% in the CP+SOC and 65.0% in the SOC group (difference, −3.7%; 95% Confidence Interval [CI], −18.8%-11.3%). The results were similar in the subgroups of severe and critically ill. There was no significant difference between CP+SOC and SOC groups in prespecified secondary outcomes, including 28-day mortality, days alive and free of respiratory support and duration of invasive ventilatory support. Inflammatory and other laboratorial markers values on days 3, 7 and 14 were similar between groups.Conclusions CP+SOC did not result in a higher proportion of clinical improvement on at day 28 in hospitalised patients with COVID-19 compared to SOC alone.In this open-label, randomised clinical trial, two infusions of convalescent plasma therapy plus standard of care compared to standard of care did not result in a higher proportion of clinical improvement on day 28 in hospitalized patients with severe COVID-19.
