Clinical effectiveness, safety, and viral mutagenicity of oral favipiravir for COVID-19: results from a community-based, open-label, randomized Phase III trial.

ABSTRACT: Early community treatment of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection may reduce severe coronavirus disease (COVID-19) incidence. We evaluated clinical effectiveness, safety, and SARS-CoV-2 mutagenicity of favipiravir, an oral viral RNA polymerase inhibitor. We performed an open-label, community-based, randomized Phase III trial, recruiting non-hospitalized adults with mild COVID-19 (WHO ordinal severity score [OSS] ≤ 3). Positive cases were invited to web-based self-screening within 24 h using public health data. Exclusion criteria included symptoms for >7 days, pregnancy/breastfeeding, severe renal/liver disease, gout, and licensed antiviral eligibility. Participants were randomized 1:1 to 10 days favipiravir (Day 1: 3,600 mg; days 2-10: 1,600 mg) or no addi
