Up to 240 patients with confirmed COVID-19 pneumonia with a baseline imputed PaO2/FiO2 ≤200 receiving oxygen therapy via a high flow nasal cannula (HFNC) or non-invasive ventilation (NIV) will be enrolled at up to 40 sites. All patients will receive three doses of Auxora.~Patients with severe hypoxemic respiratory failure, those on HFNC with a recorded worst imputed PaO2/FiO2 ≤100 between the end of the infusion of Auxora at 24 hours and the start of the infusion of Auxora at 48 hours or are on NIV or IMV at the start of the infusion of Auxora at 48 hours, will be randomized 1:1 to receive 1.6 mg/kg (1 mL/kg) of Auxora or 1 mL/kg of Placebo at 72, 96 and 120 hours from the SFIA. Patients on IMV will be stratified between the Auxora and Placebo groups. Patients without severe hypoxemic respiratory failure, those with a recorded worst imputed PaO2/FiO2 >100 between the end of the infusion of Auxora at 24 hours and the start of the infusion of Auxora at 48 hours and are not on NIV or IMV, will not be randomized for further infusions but will remain in the study and complete all assessments through Day 60.~Patients enrolled in the study should receive dexamethasone, or equivalent dose of another corticosteroid, as standard of care. The use of remdesivir should be considered and the use of tocilizumab is encouraged.
Up to 240 patients with confirmed COVID-19 pneumonia with a baseline imputed PaO2/FiO2 ≤200 receiving oxygen therapy via a high flow nasal cannula (HFNC) or non-invasive ventilation (NIV) will be enrolled at up to 40 sites. All patients will receive three doses of Auxora. Patients who continue to have severe hypoxemic respiratory failure at 48 hours will be randomized to receive three additional doses of Auxora or three doses of placebo. All patients will be followed for 60 days after enrollment into the study.
