Safety, Tolerability, and Pharmacokinetics of SAB-185 in Healthy Participants

Completed · Phase 1 · Has a placebo group

Conditions studied: COVID-19, SARS-CoV2

In brief

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 healthy participants.

• Treatment or participation in another clinical trial of any other investigational agent within 30 days prior to enrollment.
• Use of other drugs that, in the opinion of the investigator, could complicate analysis of SAB-185.
• Subjects with the following risk factors:
