COVID COVID-19 SARS-CoV-2 SARS (Severe Acute Respiratory Syndrome) | Biological: Hyperimmune immunoglobulin to SARS-CoV-2 (hIVIG) Other: Placebo Drug: Remdesivir | Phase 3 |
The primary endpoint of this trial in hospitalized patients is an ordinal outcome based on the patient's clinical status on Day 7. It includes 7 mutually exclusive categories capturing the range of organ dysfunction that may be associated with progression of COVID-19, such as respiratory dysfunction and coagulation-related complications. The ordinal endpoint is defined as follows:
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
Secondary endpoints include time to the 3 least favorable categories, time to the 2 most favorable categories, and the pulmonary only and thrombotic only components of the primary ordinal outcome. Mortality, adverse events (AEs), including infusion reactions, and biological correlates of therapeutic activity are also assessed. Because there is no established endpoint for evaluating the clinical efficacy of treatments for COVID-19, other clinically relevant outcomes, including outcomes used in other COVID-19 treatment trials, will be recorded. Thus, the randomized groups (hIVIG + SOC versus placebo + SOC ) can be compared for multiple outcomes, and results can be compared or combined with other trials.
Participants will be randomized (1:1) to a single infusion of hIVIG + SOC or placebo + SOC on the day of randomization (Day 0). Participants taking remdesivir prior to randomization may be enrolled if eligibility criteria are met. Randomized participants who were not taking remdesivir before randomization will start taking remdesivir immediately following the infusion of hIVIG or placebo unless remdesivir is contraindicated. Participants will be followed for 28 days and, if the trial goes to completion, the primary analysis will be completed after all participants are followed for 28 days.

Experimental: Intervention Group
Participants in this group will receive the investigational product and standard of care (SOC).
|
Biological: Hyperimmune immunoglobulin to SARS-CoV-2 (hIVIG)
Hyperimmune immunoglobulin to SARS-CoV-2 (hIVIG) is derived from the plasma of individuals who recover and develop neutralizing antibodies. Participants will receive a single infusion. Drug: Remdesivir Remdesivir will be given to participants in both groups as standard of care (SOC). |
Placebo Comparator: Control Group
Participants in this group will receive a placebo and standard of care (SOC).
|
Other: Placebo
Participants will receive a single infusion of the placebo (saline). Drug: Remdesivir Remdesivir will be given to participants in both groups as standard of care (SOC). |
- Ordinal Outcome Scale - Day 7 [ Time Frame: 7 days ]
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 based on the patient's clinical status on Day 7. It includes 7 mutually exclusive categories capturing the range of organ dysfunction that may be associated with progression of COVID-19, such as respiratory dysfunction and coagulation-related complications.
Minimum value = 1, Maximum value = 7 Higher scores mean a worse outcome
- Primary Safety Outcome - Death, SAE or Grade 3 or 4 Events Through Day 7 [ Time Frame: Through Day 7 ]Number of participants with death, SAE or Grade 3 or 4 event through Day 7
- N Reaching 3 Least Favorable Categories [ Time Frame: All of follow-up (through Day 28) ]N Reaching 3 least favorable categories of ordinal outcome (Categories 5, 6, 7: life-threatening end organ dysfunction, end organ failure, or death)
- N Reaching 2 Most Favorable Categories [ Time Frame: All of follow-up (through Day 28) ]N Reaching 2 most favorable categories of ordinal outcome (Categories 1 and 2: not requiring oxygen with or without limiting symptoms due to COVID-19)
- N Discharged or in Most Favorable Category [ Time Frame: All of follow-up (through Day 28) ]N discharged from hospital or reaching most favorable ordinal category (category 1: not requiring oxygen and no limiting symptoms due to COVID-19)
