Study Endpoints
Primary Endpoints
Cohort A: Percentage of Participants Who Have a Symptomatic RT-qPCR Confirmed SARS-CoV-2 Infection (Broad-term) During the EAP
Up to 1 month

Symptomatic SARS-CoV-2 infection (broad-term) is defined as a positive central lab SARS-CoV-2 RT-qPCR result (either NP, nasal or saliva) associated with signs and symptoms with the onset date occurring within 14 days of a positive RT-qPCR during the EAP. Percentage estimated by Logistic Regression.

Cohort B: Percentage of Participants Who Subsequently Develop Signs and Symptoms (Broad-Term) Within 14 Days of a Positive RT-qPCR at Baseline or During the EAP
Up to 14 Days

The percentage of participants was estimated by using the logistic regression model with fixed categorical effects of treatment group, age group (age in years:\>=12 to=50), and region (US vs ex-US).

Cohort A and Cohort B: Number of Participants With at Least One Treatment-emergent Adverse Event (TEAEs) and Severity of TEAEs
Up to 8 months
Secondary Endpoints
Cohort A and Cohort B: Percentage of Participants With High Viral Load in Nasopharyngeal (NP) Swab Samples During the EAP
Up to 1 month
Cohort A: Number of Weeks of Symptomatic RT-qPCR Confirmed SARS-CoV-2 Infection (Broad Term) During the EAP
Up to 1 month
Cohort A and Cohort B: Number of Weeks of High Viral Load in NP Swab Samples During the EAP
