Criteria

Key Inclusion Criteria:

• Has SARS-CoV-2-positive diagnostic test (from a sample collected ≤72 hours prior to randomization, using a validated SARS-CoV-2 antigen, RT-PCR, or other molecular diagnostic assay, and an appropriate sample such as nasopharyngeal [NP], nasal, oropharyngeal [OP], or saliva)

• Has symptoms consistent with COVID-19, as determined by the investigator, with onset ≤7 days before randomization

• Maintains O2 saturation ≥93% on room air

• Is able to understand and complete study-related questionnaires (patients aged ≥12 years only)

Key Exclusion Criteria:

• Was admitted to a hospital for COVID-19 prior to randomization, or is hospitalized (inpatient) for any reason at randomization

• Has participated, or is participating, in a clinical research study evaluating COVID-19 convalescent plasma, mAbs against SARS-CoV-2 (eg, bamlanivimab), or intravenous immunoglobulin (IVIG) within 3 months or within 5 half-lives of the investigational product (whichever is longer) prior to the screening visit

• Prior, current, or planned future use of any of the following treatments: COVID-19 convalescent plasma, mAbs against SARS-CoV-2 (eg, bamlanivimab), IVIG (any indication), systemic corticosteroids (any indication), or COVID-19 treatments (authorized, approved, or investigational)

• Prior use (prior to randomization), current use (at randomization) or planned use (within 90 days of study drug administration or per current CDC recommendations, as applicable) of any authorized or approved vaccine for COVID-19

• Has participated, is participating or plans to participate in a clinical research study evaluation any authorized, approved or investigational vaccine for COVID-19
