Brief Summary:
To determine the effect of favipiravir + SOC v. SOC on COVID-19 viral clearance.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Favipiravir + Standard of Care Drug: Standard of Care Phase 2

Detailed Description:

This is an open label, randomized, controlled, multicenter Phase 2 proof-of-concept study of favipiravir in hospitalized subjects with COVID-19. Subjects will be randomized within their study site and stratified by the severity of their disease to receive either favipiravir + standard of care (SOC) or SOC alone.

The dose regimen will be 1800 mg favipiravir BID plus SOC or SOC alone on Day 1 followed by 1000 mg BID favipiravir (800 mg BID for subjects with Child-Pugh A liver impairment) plus SOC or SOC for the next 13 days.

The study will have 14 days of treatment and 46 days of follow-up.

Approximately 50 patients are planned to be enrolled in the trial at approximately 8 study sites in the US.

Standard of Care




Primary Outcome Measures :
  1. Time to viral clearance [ Time Frame: Day 29 ]
    To determine the effect of favipiravir + SOC v. SOC on viral clearance of COVID-19 as measured by nasopharyngeal and oropharyngeal sampling


Secondary Outcome Measures :
  1. Status of clinical recovery as measured by the study-specific 6-point ordinal scale on Day 15 [ Time Frame: through Day 15 ]
    To determine the clinical benefit of administering favipiravir plus SOC compared to SOC alone, clinical benefit will be measured using a study-specified ordinal scale on Day 15 in adult patients hospitalized with COVID-19.

  2. Clinical effect of favipiravir + SOC compared to SOC measured by the National Early Warning Score 2 (NEWS2) [ Time Frame: through Day 29 ]
    The NEWS is based on a simple aggregate scoring system in which a score is allocated to physiological measurements, already recorded in routine practice, when patients present to, or are being monitored in hospital. Six simple physiological parameters form the basis of the scoring system: respiration rate, oxygen saturation, systolic blood pressure, pulse rate, level of consciousness or new confusion, temperature.

  3. Characterize the pharmacokinetics (PK) of favipiravir in plasma: Cmax) [ Time Frame: through Day 14 ]
    Measurement of maximum plasma concentration

  4. Characterized the pharmacokinetics (PK) of favipiravir in plasma: Cmin [ Time Frame: through Day 14 ]
    Measurement of minimum plasma concentration

  5. Characterized the pharmacokinetics (PK) of favipiravir in plasma: AUC [ Time Frame: through Day 14 ]
    Measurement of the area under the curve of plasma concentration versus time profile
