  • Vaccination for SARS-CoV-2 or self-reported history of SARS-CoV-2 infection < 4 months prior to screening.
  • Received any approved, authorized, or investigational direct acting antiviral drug against SARS-CoV-2 for the treatment of COVID-19 < 28 days or < 5 half-lives, whichever is longer, before enrollment.
  • Suspected or confirmed concurrent active systemic infection other than COVID-19 (including influenza) that may interfere with the evaluation of response to the study intervention.
  • Any of the following abnormal laboratory results at screening: a. ALT ≥ 5 × ULN b. eGFR < 60 mL/min/1.73 m2 for ≥ 1 year of age c. Serum creatinine: > 2.0 mg/dL for < 48 hours of life; > 2 × ULN for age for ≥ 48 hours of life to 1 year of age (refer to table on page 35 of protocol)
