Primary Outcome Measures
NameTimeMethod
Change in viral loadBaseline through Day 8

Change in viral load from baseline to Day 8 based on quantitative reverse-transcription polymerase chain reaction of COVID-19 virus from oropharyngeal swab collection

Incidence of adverse events (AEs) (safety)Baseline through study completion at up to 30 days

Safety as assessed by incidence of AEs by type, frequency, severity, and causality using the FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials

Secondary Outcome Measures
NameTimeMethod
Participant perceived disease progressionBaseline through Day 15

Participants rate their progression of disease on Day 8 and Day 15 when asked "Have your COVID symptoms gotten worse since treatment?" Yes or No response

Rate of COVID-19-related medical visitsBaseline through Day 30

Determine the proportion of participants having COVID-19-related medically attended visits, emergency department assessments, hospitalization or all-cause mortality

Change in viral loadBaseline through Day 11

Change in viral load from baseline to Day 4, Day 11 and Day 15 based on quantitative reverse-transcription polymerase chain reaction of COVID-19 virus from oropharyngeal swab collection

Patient rated responseBaseline through D15

Proportion of participants scoring ≥ +1 and those scoring ≤ -1 using a patient global impression of change (PGIC) 7-point categorical scale on Day 8 and Day 15 when responding to the question "In terms of your COVID-19 symptoms, how much benefit if any did you receive from the treatment?" The 7-point scale range is -3 to +3 where -3 is "very much worse" to +3 "very much improved" based on how the participant feels post-treatment
