Brief summary
The primary objective of this study was to evaluate if the addition of zanubrutinib to supportive care increases the respiratory failure-free survival rate at Day 28 in participants hospitalized for Corona Virus Disease 2019 (COVID-19) and pulmonary distress not receiving mechanical ventilation.
Interventions
320 mg (4 x 80 mg) capsules administered orally once daily
Supportive care treatment was selected and administered as deemed appropriate by the study investigator

Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Respiratory Failure-free Survival | Up to Day 28 | Number of participants with respiratory failure-free survival, defined as not having died or gone into respiratory failure on or before Day 28 |
| Time to Breathing Room Air | Up to 7 months | Time to return to breathing room air is defined as the time from randomization date to the earliest time where the participant is stable on room air without supplemental oxygen. Total follow-up time in days is the total time of all participants from the randomization date to the first event date or Day 28 if there is no event. The rate was calculated as total number of events in which a participant returned to breathing room air on or before Day 28 divided by the total follow-up time in days. |
