Trial Design The FSD201 COVID-19 Trial is a randomized, controlled, double-blind, multicenter study, conducted on 352 patients to assess the efficacy and safety of FSD201 dosed at 600mg or 1200mg twice-daily, together with standard of care ("SOC") compared to SOC alone in hospitalized patients with documented COVID-19 disease. Eligible patients will present symptoms consistent with influenza/coronavirus signs (fever, dry cough, malaise, difficulty breathing) and newly documented positive COVID-19 disease.
