A Study to Evaluate the Effect of RBT-9 on Progression of COVID-19 in High-Risk Individuals (The PREVENT Study)
Study Details
Study Description
Brief Summary
The overall objective is to evaluate the efficacy, tolerability, and safety of a single dose of RBT-9 versus placebo in coronavirus disease 2019 (COVID-19) infection in non-critically ill adults who are at high risk of progression.

Outcome Measures
Primary Outcome Measures
- Evaluate the effect of RBT-9 versus placebo on clinical status of COVID-19 patients as measured using the 8-point World Health Organization (WHO) Ordinal Clinical Scale [28 days]
Determining severity of COVID-19 in patients measured using the 8-point World Health Organization (WHO) Ordinal Clinical Scale which measures the clinical status of a subject at the first assessment of a given day with category 1, most favorable, and category 8, least favorable (1. Ambulatory, no limitation of activities; 2. Ambulatory, limitation of activities; 3. Hospitalized, no oxygen therapy; 4. Hospitalized, oxygen by mask or nasal prongs; 5. Hospitalized, non-invasive ventilation or high-flow oxygen; 6. Hospitalized, intubation and mechanical ventilation; 7. Hospitalized, ventilation plus additional organ support - pressors, renal replacement therapy [RRT], extracorporeal membrane oxygenation [ECMO]; 8. Death)
Secondary Outcome Measures
- Time to first occurrence of death from any cause or new/worsened organ dysfunction [28 Days]
Time to first occurrence of either death from any cause or new/worsened organ dysfunction through Day 28, defined as at least one of the following: 1. Respiratory decompensation; 2. New or worsening congestive heart failure; 3. Requirement of vasopressor therapy and/or inotropic or mechanical circulatory support; 4. Ventricular tachycardia or fibrillation lasting at least 30 seconds and/or associated with hemodynamic instability or pulseless electrical activity, or resuscitated cardiac arrest; 5. Initiation of renal replacement therapy
- All-cause survival [28 Days]
Percentage of subjects who are alive at Day 28
- Oxygen saturation (SpO2)/fraction of inspired oxygen (FiO2) ratio [28 Days]
Among subjects who begin oxygen therapy, mean change from initiation to last day on oxygen or Day 28 (whichever happens first) in SpO2/FiO2 ratio
- Fever incidence [28 Days]
Percentage of subjects with fever through Day 28
- Acute kidney injury (AKI) incidence [28 Days]
Percentage of subjects who develop AKI (defined as an increase in serum creatinine by 0.5 mg/dL or more within 48 hours or an increase in serum creatinine to 1.5 × Baseline or more within the last 7 days) through Day 28
- New or worsening congestive heart failure (HF) [28 Days]
Percentage of subjects with new or worsening congestive HF through Day 28
- Hospitalization status [28 Days]
Percentage of subjects who remain hospitalized at Day 28
- Ventricular tachycardia or fibrillation lasting at least 30 seconds and/or associated with hemodynamic instability or pulseless electrical activity, or resuscitated cardiac arrest [28 Days]
Percentage of subjects with ventricular tachycardia or fibrillation lasting at least 30 seconds and/or associated with hemodynamic instability or pulseless electrical activity, or resuscitated cardiac arrest through Day 28
- Oxygen-free days [28 Days]
Number of oxygen-free days through Day 28
- Intensive care unit (ICU) status [28 Days]
Percentage of subjects transferred to the ICU through Day 28
- Days on ventilator [28 Days]
Number of days on mechanical ventilation through Day 28
- Time to and duration of vasopressor or inotrope utilization [28 Days]
Time to and duration of vasopressor or inotrope utilization through Day 28
- Dialysis status [28 Days]
Percentage of subjects who begin dialysis through Day 28
