4. Moderate or Severe illness per NIH COVID-19 Treatment Guidelines:
Moderate” Illness: Symptoms such as cough, fever, sore throat, malaise, myalgias, headache; and Evidence of lower respiratory tract disease by clinical assessment and/or imaging; and SpO2 >93% on room air at sea level
Severe” Illness, including any of the following: Respiratory rate >30 breaths/minute; or SpO2 =93% on room air at sea level; or Ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) <300; or Lung infiltrates >50% of pulmonary volume on imaging
5. Female subjects must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) within 24 hours prior to the start of investigational product.
6. Female subjects of childbearing potential and male subjects with partners of childbearing potential must agree to use adequate methods of contraception during the study and through 90 days after the last dose of study medication. Female subjects of childbearing potential are all those except subjects who are surgically sterile, who have medically documented ovarian failure, or who are at least 1 year postmenopausal.
a. For females: 2 of the following contraceptive methods, with at least 1 being a barrier method:
- Hormonal contraceptives for = 27 days before dosing
- Intrauterine device (IUD) in place = 27 days before dosing
- Double-barrier methods (use of condom [male partner] with either diaphragm with spermicide or cervical cap with spermicide) from screening
- Surgical sterilization of the partner (vasectomy = 1 month before screening)
- Female subjects must have a negative urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) within 24 hours prior to the start of investigational product.
b. For males:
Surgical sterilization (vasectomy = 1 month before screening)
Or
Both of the following contraceptive methods from screening:
- Consistently and correctly use a condom
- Partner must use a hormonal contraceptive or a nonhormonal barrier method (IUD or diaphragm with spermicide or cervical cap with spermicide).

- Bone marrow or solid organ transplantation
- Any serious condition that, in the opinion of the investigator, would preclude evaluation of response or make it unlikely that the contemplated course of therapy and follow-up could be completed
