SEVERE OR CRITICAL COVID-19 DISEASE: Severe disease: requires supplemental oxygen administration by nasal cannula, simple face mask, or other similar oxygen delivery device. Critical disease: Requires supplemental oxygen delivered by nonrebreather mask or high-flow nasal cannula or use of non-invasive or invasive ventilation or requiring treatment in an intensive care unit |
|
|
|
|
|
AND at least one of the following: Not receiving supplemental oxygen and |
|
|
|
|
|
having a blood oxygen saturation of <=93% sustained for 5 minutes (corresponds |
|
|
|
|
|
to category 3 on the 6-point ordinal scale) OR receiving supplemental oxygen |
|
|
|
|
|

of mercury (mmHg) while on invasive mechanical ventilation or veno-venous ECMO |
|
|
|
|
|
for less than 48 hours prior to screening) (corresponds to category 5 on the |
|
|
|
|
|
-point ordinal scale) |

|
|
|
|
|
|
Received an investigational intervention (including investigational vaccines) or used an invasive investigational medical device within 30 days before the planned dose of study intervention. Note: the investigator must ensure that the participant is not enrolled in another COVID-19 study with an investigational intervention (apart from the exception specified below) prior to completion of Day 28 of the current study. Exception: participation in a single arm study, a non-blinded controlled study, expanded access, compassionate use program or any other program that is not a blinded study is allowed if it is conducted with one of the following: agents with demonstrated in vitro-effect against SARSCoV- 2, as mentioned in the center of disease control and prevention (CDC) guidelines and convalescent plasma

|
|
|
Has a history of respiratory condition (that is, asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, fibrotic lung disease) that requires home oxygen supplementation, supportive non-invasive ventilation or, is status/post lung volume reduction surgery (LVRS). Exception: Participants with sleep apnea using supportive non-invasive ventilation (continuous positive airway pressure [CPAP]) at screening may be included
