Follow-up duration (days): 28
|Inclusion criteria||Age 18-75 years, infection with SARS-CoV-2 virus confirmed by RT-PCR within 48 hours prior to randomization, no participation in any other interventional clinical study, agreement to use effective contraception during the study and for ≥7 days following the last treatment, and, for female patients of child-bearing potential, a negative pre-treatment pregnancy test|
|Exclusion criteria||Severe infection (defined as need for invasive or non-invasive ventilator support, extracorporeal membrane oxygenation [ECMO] or shock requiring vasopressor support), oxygen saturation ≤93% or arterial oxygen partial pressure or fraction of inspired oxygen of ≤300 mmHg, requiring ICU care for management of ongoing clinical status, inability to take or tolerate oral medications, allergy or hypersensitivity to favipiravir, asthma or chronic obstructive lung disease, severe liver disease (underlying liver cirrhosis or alanine aminotransferase/aspartate aminotransferase elevated over 5 times the upper limit of normal [ULN]), history of gout or hyperuricemia (above the ULN), prolonged QT (defined as QTcF ≥450 msec for men and as QTcF ≥470 msec for women), severely reduced left ventricular function (ejection fraction <30%), or severe renal impairment (creatinine clearance <30 mL/min), or having received continuous renal replacement therapy, hemodialysis or peritoneal dialysis|
Favipiravir (800 mg)Co-Intervention: Standard care
Duration : 14 days
Definition of Standard care: Standard supportive care … included antipyretics, cough suppressants, antibiotics, and vitamins. Drugs thought to have antiviral activity against SARS CoV- 2 (including hydroxychloroquine) were prohibited. Prohibited concomitant medications included hydroxychloroquine or chloroquine, pyrazinamide, repaglinide, theophylline, and famciclovir or sulindac.
Duration : 14 days
150 participants (n1=75 / n2= 75)
|Characteristics of participants|
Mean age : 43.3
Severity : Mild: n=89 / Moderate: n=58/ Severe: n=0 Critical: n=0
|In the register|
Time until cessation of oral shedding of SARS-CoV-2 virus [ Time Frame: Up to 28 days ] (Time in days from randomization to a negative SARS-CoV2 RT-PCR result of both oropharyngeal swab and nasopharyngeal swab).
|In the report|
Time from randomization to cessation of oral shedding of the SARS-CoV-2 virus (28-days maximum; specified as a negative RT-PCR result for both oropharyngeal and nasopharyngeal swabs)
|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
In addition to the published pre-proof article, the study's prospective registry was used for data extraction and assessment of risk of bias. Neither the study protocol nor statistical analysis plan were available at time of data extraction. There were no substantive differences between the published article and trial registry in population, procedures, treatment or outcomes. The study achieved its pre-stated sample size.
