Study Endpoints
Primary Endpoints
Change From Baseline in Logarithm Base 10 (Log10) Transformed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Ribo Nucleic Acid (RNA) Level on Day 5
Baseline (Day 1), Day 5

Change from baseline in SARS-CoV-2 RNA level at Day 5 was analyzed using Mixed Effects Repeated Measures (MMRM) model with fixed effects including treatment, visit, visit by treatment interaction, and baseline viral load. Covariates included days from baseline since symptom onset (\<=3 versus \[vs.\] \>3 days), vaccination status (complete or partial vs. unvaccinated), baseline anti-N serology status and age at screening (years). Participants were excluded from the analysis if baseline viral load was less than 4\*log10 copies/milliliter, missing, or not detected.

Secondary Endpoints
Change From Baseline in Log10 Transformed SARS-CoV-2 RNA Level on Days 3, 10 and 14
Baseline (Day 1), Day 3, Day 10 and Day 14

From start of study intervention up to 28 days after last dose of study intervention (up to 33 days)
Number of Participants With Treatment Emergent Adverse Events (TEAEs) Leading to Discontinuations
From start of study intervention up to 28 days after last dose of study intervention (up to 33 days)
