Summary:

      The objective of this study is to evaluate the efficacy of oral favipiravir plus standard of

             study medication

          -  Females must be unable to bear children, OR ensure that their male partner is
             incapable of fathering a child, OR, if of childbearing potential will strictly adhere

             of study medication

          -  Females must agree to stop breast-feeding prior to first dose of study drug and

          -  Females must have a negative pregnancy test at screening

          -  Participant agrees to maintain home or other quarantine as recommended by the study
             physician, except to visit the study site as required by the protocol

        Exclusion Criteria:

          -  Concomitant bacterial respiratory infection documented by respiratory culture. NOTE:
             Subjects on empirical antibiotic treatment for possible but unproven bacterial
             pneumonia, but who are positive for SARS-CoV-2, are allowed in the study (will be
             randomized to the same treatment to maintain blinding).

          -  History of abnormal uric acid metabolism.

          -  History of hypersensitivity to an anti-viral nucleoside-analog drug targeting a viral
             RNA polymerase.

          -  Abnormal laboratory test results at screening:

          -  Use of adrenocorticosteroids (except topical or inhaled preparations or oral
             preparations equivalent to or less than 10 mg of oral prednisone) or immunosuppressive
             or immunomodulatory drugs (e.g., immunosuppressants, anticancer drugs, interleukins,
             interleukin antagonists or interleukin receptor blockers). NOTE: Treatment of study
             participants following institutional COVID-19 treatment policies or guidelines,
             including the use of immunomodulatory medications, is permitted. This excludes
             treatment with agents that have the potential for direct antiviral activity, including
             convalescent plasma and NO, and co-enrollment into other clinical studies that
             evaluate investigational agents for COVID-19.

          -  Serious chronic disease (e.g., human immunodeficiency virus [HIV], cancer requiring
             chemotherapy within the preceding 6 months, and/or moderate or severe hepatic
             insufficiency).

          -  Previously received favipiravir within the past 30 days.
