may be healthy, high-risk conditions, or immunocompromised).

3. Prior to SARS CoV 2 infection, has the ability to carry out self-care activities of
daily living (basic ADL)

4. Have lower respiratory tract infection (LRTI) confirmed by CT imaging, with or without
contrast, to involve at least 2 lobes of the lung.

chance of survival during the first 10 days of treatment

2. Subjects with Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), or
Alkaline Phosphatase (ALP) =3x ULN and Total Bilirubin (TBILI) =2x ULN Note: Subjects
with ALT/AST/ALP = 3x ULN AND TB =2x ULN that have been chronically stable (for >1
year on more than one assessments) due to known liver pathology including malignancy
(primary or metastasis), chronic medications, transplantation, or chronic infection
will not be excluded

3. Female subjects breastfeeding or planning to breastfeed at any time through 30 days

concurrent viral, bacterial, or fungal infection and meet at least one of the
following criteria:

- Has evidence of vital organ failure outside of the lung (e.g., liver, kidney)

- Requires vasopressors to maintain blood pressure

For COVID-19 sub study:

1. Subjects requiring invasive mechanical, Bi-PAP or CPAP ventilation at randomization.

2. Subjects receiving any other investigational or empiric treatment for SARS-2-CoV
(either as part of a clinical trial or under emergency approval (approved agents for
the management of symptoms, e.g., fever, are permitted).

3. Subjects who are known HIV-positive (and not undetectable at most recent HIV RNA
assessment)

4. Subjects who are currently taking immunomodulating biologics (e.g, interferons,
interleukin)

5. Subjects with severe sepsis due to either their SARS-CoV-2 infection or a concurrent
viral, bacterial, or fungal infection and meeting at least one of the following
criteria:

- Have evidence of vital organ failure outside of the lung (e.g., liver, kidney)

- Require vasopressors to maintain blood pressure

6. Subjects meeting exclusion criteria #2, 3, 5 and 6 of the main study
