  19. Mean Change in FLU PRO Plus Total Score (AUC) [ Time Frame: Through Day 7 ]

    Mean change in InFLUenza Patient-Reported Outcome (FLU-PRO Plus) questionnaire total score.

    The FLU-PRO is a 32-item daily diary assessing influenza symptoms and severity across 6 body systems (nose, throat, eyes, chest/respiratory, gastrointestinal, and body/systemic). The FLU-PRO Plus includes the 32-item FLU-PRO with 2 additional items for loss of smell and taste. The mean total score can range from 0 (symptom free) to 4 (very severe symptoms) and was calculated as the arithmetic mean of the 32 items within FLU-PRO. Missing total score at day 7 was imputed using a modified last observation carried forward approach.


  20. Time to Symptom Alleviation Using FLU-PRO Plus [ Time Frame: Through Day 21 ]

    Symptom alleviation is defined as absence of the majority of core symptoms of COVID-19 (except for cough or fatigue, where scoring no more than 'somewhat' in severity, and loss of smell or taste were allowed) as measured by FLU-PRO Plus, sustained for >=48 hours. Participants could only achieve sustained symptom alleviation following >=2 non-missing consecutively scored questionnaires that showed symptom alleviation. Participants who did not achieve sustained symptom alleviation were censored at Day 21, the day of death, or the day of withdrawal, whichever was earliest. Days where symptom alleviation could not be assessed to a missing/incomplete questionnaire were imputed as no symptom alleviation.

    The FLU-PRO is a 32-item daily diary assessing influenza symptoms and severity across 6 body systems (nose, throat, eyes, chest/respiratory, gastrointestinal, and body/systemic). The FLU-PRO Plus includes the 32-item FLU-PRO with 2 additional items for loss of smell and taste.


  21. Change From Baseline in Viral Load in Nasal Secretions by qRT-PCR at Day 8 [ Time Frame: Baseline and Day 8 ]
  22. Number of Participants Who Progressed to Develop Severe and/or Critical Respiratory COVID-19 as Manifested by Requirement for and Method of Supplemental Oxygen Through Day 8 [ Time Frame: Through Day 8 ]
  23. Number of Participants Who Progressed to Develop Severe and/or Critical Respiratory COVID-19 as Manifested by Requirement for and Method of Supplemental Oxygen Through Day 15 [ Time Frame: Through Day 15 ]
    Participants were defined as progression to severe respiratory COVID-19 if they required supplemental oxygen either by nasal cannula, face mask, high-flow oxygen devices, or non-invasive ventilation. Participants were defined as progression to critical respiratory COVID-19 if they required invasive mechanical ventilation or ECMO.

  24. Number of Participants Who Progressed to Develop Severe and/or Critical Respiratory COVID-19 as Manifested by Requirement for and Method of Supplemental Oxygen Through Day 22 [ Time Frame: Through Day 22 ]
    Participants were defined as progression to severe respiratory COVID-19 if they required supplemental oxygen either by nasal cannula, face mask, high-flow oxygen devices, or non-invasive ventilation. Participants were defined as progression to critical respiratory COVID-19 if they required invasive mechanical ventilation or ECMO.

  25. Number of Participants Who Progressed to Develop Severe and/or Critical Respiratory COVID-19 as Manifested by Requirement for and Method of Supplemental Oxygen Through Day 29 [ Time Frame: Through Day 29 ]
    Participants were defined as progression to severe respiratory COVID-19 if they required supplemental oxygen either by nasal cannula, face mask, high-flow oxygen devices, or non-invasive ventilation. Participants were defined as progression to critical respiratory COVID-19 if they required invasive mechanical ventilation or ECMO.

  26. 29-day All-cause Mortality [ Time Frame: Through Day 29 ]
    Participants alive at the respective follow-up timepoint were censored at that timepoint; participants who withdrew prior to the respective timepoint were censored at the time of study withdrawal

  27. 60-day All-cause Mortality [ Time Frame: Through Day 60 ]
    Participants alive at the respective follow-up timepoint were censored at that timepoint; participants who withdrew prior to the respective timepoint were censored at the time of study withdrawal

  28. 90-day All-cause Mortality [ Time Frame: Through Day 90 ]
    Participants alive at the respective follow-up timepoint were censored at that timepoint; participants who withdrew prior to the respective timepoint were censored at the time of study withdrawal
