    4. Use of other drugs that, in the opinion of the investigator, could complicate analysis of SAB-185.
    5. Subjects with the following risk factors:
  • Compromised immune system including confirmed diagnosis of current cancer under treatment, inherited deficiencies of the immune system, immune suppressing medication, or other conditions causing leukopenia or neutropenia
  • Known autoimmune condition requiring therapy more intensive than intermittent non-steroidal anti-inflammatories in the prior 6 months (for example: rheumatoid arthritis, lupus, inflammatory bowel disease)

Any other underlying medical (cardiac, liver, renal, neurological, respiratory) or psychiatric condition that in the view of the investigator would preclude use of SAB-185 8. Known IgA deficiency or previous allergic reaction to intravenous immunoglobin (IVIG)/subcutaneous immunoglobin (SCIG) 9. Positive for hepatitis B virus surface antigen, hepatitis C virus antibody, or HIV antibody by medical history 10. History of allergy, anaphylaxis, or severe reaction to beef products (including milk and gelatin).

5. Study Description

Brief Summary
: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SAB Biotherapeutics has developed SAB-185, an Anti-SARS-CoV-2 Human Immunoglobulin Intravenous (transchromosomic [Tc] bovine-derived), as a potential therapeutic to treat COVID-19. This study will evaluate the safety, immunogenicity, and pharmacokinetics of SAB-185 in ambulatory participants with COVID-19.

Intervention Name(s)
SAB-185
Other Intervention Name(s)
Anti-SARS-CoV-2 Human Immunoglobulin Intravenous (Tc bovine-derived)
Intervention Description
SAB-185 is a purified human immunoglobulin G (hIgG) designed to specifically bind to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) viruses. SAB-185 is purified from the plasma of immunized Tc bovines that were immunized initially (vaccinations 1 and 2) with a plasmid DNA (pDNA) vaccine that expresses wild-type SARS-CoV-2 spike protein, followed by additional immunizations (vaccinations 3 and beyond) with a recombinant spike protein from SARS-CoV-2 produced in insect cells. The purified hIgG is a sterile liquid formulated in 10 mM glutamic acid monosodium salt, 262 mM D-sorbitol, 0.05 mg/mL Tween 80, pH 5.5. The drug product will be administered intravenously and will be diluted in saline per the clinical protocol.
