Abstract

In May 2020 the Russian Ministry of Health granted fast-track marketing authorization to RNA polymerase inhibitor AVIFAVIR (favipiravir) for the treatment of COVID-19 patients. In the pilot stage of Phase II/III clinical trial, AVIFAVIR enabled SARS-CoV-2 viral clearance in 62.5% of patients within 4 days, and was safe and well-tolerated.

Clinical Trials Registration. NCT04434248.

    Table 1: Rigor

    Institutional Review Board StatementConsent: The eligible patients included hospitalized men and non-pregnant women of 18 years or older who signed the informed consent form, had moderate PCR-confirmed COVID-19 (positive test at screening), were able to administrate the drug orally and willing to use adequate contraception during the study and 3 months after its completion.
    RandomizationThis was an adaptive, multicenter, open label, randomized, Phase II/III clinical trial of AVIFAVIR versus standard of care (SOC) in hospitalized patients with moderate COVID-19 pneumonia.
    Blindingnot detected.
    Power AnalysisThe “go-no-go” decision to start the pivotal stage of the study was based on the exact single-stage Phase II assessment at one-sided α=0.05 and 80% power [8].
    Sex as a biological variableThe eligible patients included hospitalized men and non-pregnant women of 18 years or older who signed the informed consent form, had moderate PCR-confirmed COVID-19 (positive test at screening), were able to administrate the drug orally and willing to use adequate contraception during the study and 3 months after its completion.
