PCR is the preferred method; however with evolving approaches to laboratory confirmation of SARS-CoV-2 infection, other molecular or antigen tests that detect viral ribonucleic acid (RNA) or protein are allowed if authorized for use in the country. Serological tests that detect host antibodies generated in response to recent or prior infection are not allowed.
Had initial onset of signs/symptoms attributable to COVID-19 for ≤5 days prior to the day of randomization and at least 1 of the following sign/symptom attributable to COVID-19 on the day of randomization.
Has mild or moderate COVID-19.
Has at least 1 characteristic or underlying medical condition associated with an increased risk of severe illness from COVID-19.
Males agree to the following during the intervention period and for at least 4 days after the last dose of study intervention: Either abstain from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent; or must agree to use contraception.
Females are not pregnant or breastfeeding, and at least one of the following conditions applies: Is not a woman of child bearing potential (WOCBP); or is a WOCBP and using a contraceptive method that is highly effective (a low user dependency method OR a user dependent method in combination with barrier method), or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) for at least 4 days after the last dose of study intervention; a WOCBP must have a negative highly sensitive pregnancy test (urine or serum test is required) within 24 hours before the first dose of study intervention.

Is on dialysis or has reduced estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73m\^2 by the Modification of Diet in Renal Disease (MDRD) equation.
Has any of the following conditions: human immunodeficiency virus (HIV) with a recent viral load \>50 copies/mL (regardless of CD4 count) or an AIDS-defining illness in the past 6 months, participants with HIV may only be enrolled if on a stable antiretroviral therapy regimen; a neutrophilic granulocyte absolute count \<500/mm\^3.
Has a history of hepatitis B virus (HBV) or hepatitis C virus (HCV) with cirrhosis, end-stage liver disease, hepatocellular carcinoma, aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) \>3X upper limit of normal at screening.
Has a platelet count \<100,000/μL or received a platelet transfusion in the 5 days prior to randomization.
Is taking or is anticipated to require any prohibited therapies.
Is unwilling to abstain from participating in another interventional clinical study through Day 29 with an investigational compound or device, including those for COVID-19 therapeutics.
Has hypersensitivity or other contraindication to any of the components of the study interventions as determined by the investigator.
Has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant or that could prevent, limit, or confound the protocol-specified assessments including but not limited to: participants who are not expected to survive longer than 48 hours after randomization, or participants with a recent history of mechanical ventilation, or participants with conditions that could limit gastrointestinal absorption of capsule contents.
