3. Severe pneumonia, acute lung injury, or acute respiratory distress syndrome confirmed by computed tomography or X-ray at Screening or within the 3 days prior to Screening, as part of the participant's routine clinical care.
4. Respiratory distress requiring mechanical ventilation, which can be either invasive (requiring endotracheal intubation) or noninvasive (with continuous positive airway pressure or bilevel positive airway pressure).
5. Female participants of childbearing potential and male participants with female partners of childbearing potential must follow protocol specified contraception guidance for avoiding pregnancy for 8 months after treatment with the study drug.

* Investigational therapies were allowed if received as part of BSC through an expanded access protocol or emergency approval for the treatment of COVID-19.
