E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to evaluate the efficacy of plasma from COVID-19 convalescent donors (COVID-19 convalescent plasma) and standard of care versus standard of care alone in preventing hospitalisation or death by day 28 after randomisation, in clinically vulnerable patients recently infected by SARS-CoV-2. Standard of care therapy may include anti-SARS-CoV-2 specific medication listed as authorized in a dedicated appendix. |
|
E.2.2 | Secondary objectives of the trial |

Requirement for supplemental oxygen 5. Requirement for non-invasive ventilation 6. Requirement for mechanical ventilation 7. The change in WHO Clinical Progression Scale score 8. The duration of hospital stay 9. The need for admission to ITU 10. The duration of ITU stay 11. Cases of long COVID-19 symptoms and the time to recovery 12. Health-related quality of life
To analyse the safety of COVID-19 convalescent plasma with regard to: 1. SAEs and unexpected AEs 2. Arterial and venous thrombotic events

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint definition: the proportion of patients hospitalised or death by day 28. The primary outcome will be analysed using logistic regression adjusted for randomisation stratification variables (results will be expressed as odds ratios with 95% confidence intervals). Adjustment for major prognostic factors will be considered depending on the evolution of medical knowledge on the prognosis of patients infected by SARS-Cov-2.
