Outpatient Treatment of Severe Acute Respiratory Syndrome Coronavirus 2 Infection to Prevent Coronavirus Disease 2019 Progression.


As of March 2021, coronavirus disease 2019 (COVID-19) had caused more than 123 million infections and almost 3 million deaths worldwide. Dramatic advances have been made in vaccine development and nonpharmaceutical interventions to stop the spread of infection. However, treatments to stop disease progression are limited. A wide variety of "repurposed" drugs evaluated for treatment of COVID-19 have had little or no benefit. More recently, intravenous monoclonal antibody (mAb) combinations have been authorized by the US Food and Drug Administration for emergency use for outpatients with mild to moderate COVID-19 including some active against emerging severe acute respiratory syndrome coronavirus 2 variants of concern. Easier to administer therapeutics including intramuscular and subcutaneous mAbs and oral antivirals are in clinical trials. Reliable, safe, effective COVID-19 treatment for early infection in the outpatient setting is of urgent and critical importance. Availability of such treatment should lead to reduced progression of COVID-19.
