About

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

Full description

This is an open label, randomized, controlled, multicenter Phase 2 proof-of-concept study of favipiravir in hospitalized subjects with Corona Virus Disease (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 bis in die (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.

Enrollment: 50 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. within 72 hours of their hospitalization for infection with Severe Acute Respiratory Syndrome - Corona Virus - 2 (SARS-CoV-2), AND,
2. within 72 hours of the latest Polymerase Chain Reaction (PCR) positive result and within 7 days of the 1st PCR positive result for SARS-CoV-2. (The latest PCR could be the only PCR result.), AND,
3. within 10 days of onset of any COVID-19 symptoms.

Exclusion criteria

1. Subject has a concomitant bacterial respiratory infection unless cleared by the Sponsor

6. Has previously received favipiravir within the past 30 days
7. Has renal insufficiency requiring hemodialysis or continuous ambulatory peritoneal dialysis (CAPD) or glomerular filtration rate of less than 20 mL/min.
8. Has liver impairment greater than Child-Pugh A.
9. Has a history of alcohol or drug abuse in the previous 6 months.
10. Has a psychiatric disease that is not well controlled where controlled is defined as: stable on a regimen for more than one year.
11. Has taken another investigational drug within the past 30 days.
