               5. Chronic cardiac conditions, including coronary artery disease (CAD), heart
                  failure, congenital heart disease, cardiomyopathy

               7. Chronic liver disease, including cirrhosis

          6. Must agree not to enroll in another study of an investigational agent or take any
             other drug that has been granted Emergency Use Authorization prior to completion of
             Day 28

          7. If women of childbearing potential (WOCBP) or men whose sexual partners are WOCBP,
             must be able and willing to use at least 1 highly effective method of contraception
             during the study and for 90 days after receiving the last dose of study drug

        Exclusion Criteria:

          1. Physician makes a decision that trial involvement is not in participants' best
             interest, or has any condition that does not allow the protocol to be followed safely

          2. Known severe liver disease (eg, Child Pugh score > 12, AST >5 times upper limit)

          3. SaO2/SPO2 ≤94% on room air condition, or the Pa02/Fi02 ratio < 300 mgHg
