Study Summary

This protocol will serve as a platform for assessing treatments for adult patients hospitalized for medical management of COVID-19 without related serious end-organ failure. Trials will involve sites around the world strategically chosen to ensure rapid enrollment. This trial will compare hyperimmune intravenous immunoglobulin (hIVIG) with matched placebo, when added to standard of care (SOC), for preventing further disease progression and mortality related to COVID-19. SOC will include remdesivir unless it is contraindicated for an individual patient.

Primary Outcome

The primary objective is to compare the clinical status of patients in each group on day 7 of follow-up using the primary ordinal outcome with 7 mutually exclusive categories: 7\. Death 6. End-organ failure 5. Life-threatening end-organ dysfunction 4. Serious end-organ dysfunction 3. Moderate end-organ dysfunction 2. Limiting symptoms due to COVID-19 1\. No limiting symptoms due to COVID-19 Outcome is reported as the percent of participants in each of 7 categories. Primary ordinal outcome bas
