Conditions

COVID-19

Brief summary

The primary objective of this study is to evaluate the safety and efficacy of intravenous (IV) infusion of ulinastatin compared to placebo with respect to time to recovery, disease severity, need for ventilator support, and mortality in patients with COVID 19.

Interventions

DRUGUlinastatin

Ulinastatin administered via IV infusion (200,000/infusion)

DRUGPlacebo

Placebo to match ulinastatin administered via IV infusion

Design outcomes

Primary

MeasureTime frameDescription
Time to recoveryUp to 29 daysTime to recovery, defined as attaining a score of 6, 7, or 8 on the COVID-19 disease severity scale, an 8 point ordinal scale used in the NIH Adaptive COVID-19 Treatment Trial (ACTT; NCT04280705). 1. = Death; 2. = Hospitalized and on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3. = Hospitalized and on non-invasive ventilation or high-flow oxygen devices; 4. = Hospitalized and requiring supplemental oxygen; 5. = Hospitalized and not requiring supplemental oxygen but requiring ongoing medical care (COVID-19-related or otherwise); 6. = Hospitalized and not requiring supplemental oxygen and no longer requiring ongoing medical care; 7. = Not hospitalized, limitation on activities and/or requiring home oxygen; 8. = Not hospitalized, no limitation on activities
