At least 18 years of age with at least one of the following risk factors: age of at least 65 years, a BMI of at least 35, chronic kidney disease, diabetes mellitus type 1 or type 2, immunosuppressive disease or receipt of immunosuppressive treatment, and an age of at least 55 years with cardiovascular disease, hypertension, or chronic obstructive pulmonary disease or another chronic respiratory disease. |
Exclusion criteria | SpO2 ≤ 93% on room air at sea level or PaO2/FiO2 < 300, respiratory rate ≥30 per minute, heart rate ≥125 per minute (FDA May 2020); Require mechanical ventilation or anticipated impending need for mechanical ventilation; known allergies to any of the components used in the formulation of the interventions; hemodynamic instability requiring use of pressors within 24 hours of randomization; Suspected or proven serious, active bacterial, fungal, viral, or other infection (besides COVID-19) that in the opinion of the investigator could constitute a risk when taking intervention; any co-morbidity requiring surgery within <7 days, or that is considered life threatening within 29 days; any serious concomitant systemic disease, condition or disorder that, in the opinion of the investigator, should preclude participation in this study; a history of a positive SARS-CoV-2 serology test; a history of a positive SARS-CoV-2 test prior to the one serving as eligibility for this study; received an investigational intervention for SARS-CoV-2 prophylaxis within 30 days before dosing; received treatment with a SARS-CoV-2 specific monoclonal antibody; received convalescent COVID-19 plasma treatment; participated, within the last 30 days, in a clinical study involving an investigational intervention. If the previous investigational intervention has a long half-life, 5 half-lives or 30 days, whichever is longer, should have passed; concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study; breast feeding; investigator site personnel directly affiliated with this study; body weight <40 kg. |

Risk of bias Overall The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review |
Some concerns |
General comment | In addition to the published article, the prospective registry, protocol and statistical analysis plan and supplementary materials were used in data extraction and assessment of risk of bias. Some primary outcomes in the registry are reported as secondary outcomes in the report, and some secondary outcomes in the registry (proportion of patients demonstrating symptom resolution or improvement, pharmacokinetics) are not reported. Otherwise there were no substantive differences in population, procedures, interventions or outcomes between the registry, protocol and statistical analysis plan and the published article. The study achieved its target sample size. |
