Has a declining clinical status with an expected survival \<3 days in the opinion of the Investigator. 9. Has received any systemic immunomodulatory or immunosuppressant agents for any condition within 3 months prior to randomization. (Note: a stable, oral, low dose of corticosteroids \[prednisone or equivalent ≤10 mg/day\] for a chronic condition or any dose of systemic corticosteroids for current COVID-19 treatment are permitted. Local/topical treatments are also permitted.) 10. Has received any biologic treatment for any acute (eg, COVID-19) or chronic conditions (eg, TNFα inhibitors, anti-IL17A, tocilizumab, anti-cytokines, etc.) within 3 months prior to randomization. 11. Is participating in another clinical study of an investigational product and/or received an investigational product within 30 days or within 5 half-lives (whichever is longer) prior to randomization. 12. Is pregnant or breastfeeding, or has a positive pregnancy serum or urine test during Screening. 13. Does not agree to use contraception in the event of sexual activity for 130 days (+90 days for male subjects) after the last dose of study drug if a female of childbearing potential or a male with a partner of childbearing potential. Note: this criterion does not apply to subjects in same-sex relationships. 14. Has inadequate hematologic function during Screening defined as follows: * Absolute neutrophil count (ANC) \<1.0 × 109/L. * ALC \<0.5 × 109/L. 15.

Has a medical, psychiatric, or other condition or circumstance that, in the opinion of the Investigator, could affect the subject's safety, the subject's participation in the study, or the reliability of the study data.
