- Duration Until Viral Shedding Cessation [ Time Frame: Assessed for up to 28 days ]Time to first of two consecutive negative respiratory secretions obtained by oropharyngeal and/or anterior nare swabs for SARS-CoV-2 by qRT-PCR.
- Change in Sars-CoV-2 Viral Load [ Time Frame: baseline, day 14 ]Log10 Oropharyngeal viral load over time, mean change at day 14 (SD). Sars-CoV-2 RNA level in oropharyngeal and/or anterior nare swabs collected daily.
- Area Under the Curve of SARS-COV-2 Viral Load [ Time Frame: baseline through day 14 ]Log10 viral load area under the curve through day 14, median (IQR). Area under the curve of SARS-CoV-2 viral load in oropharyngeal and/or anterior nare swabs collected daily.
- Duration Until Resolution of Symptoms [ Time Frame: Up to 28 days ]Duration until resolution of symptoms in days, median (95% CI). Time to alleviation of all symptoms (fever, chills, cough, nasal congestion, muscle pains), defined as the time from initiation of treatment until all symptoms are rated as absent or mild in symptomatic patients.
- Count of Participants Requiring Emergency Department Visits or Hospitalizations Within 28 Days of Initiation of Treatment [ Time Frame: 28 days ]
