¹Excludes the patient who discontinued during the double-blind phase;

²Jaundice and nausea, which followed concomitant but reversible treatment-related ALT, AST and total bilirubin elevations (patient met the biochemical criteria for Hy’s law; aminotransferases, jaundice and nausea resolved off-treatment and patient achieved SVR12);

³Fatality (stab wound) unrelated to treatment;

⁴Treatment related: Study drug overdose (n = 2);

⁵Unrelated to treatment: Ventricular extrasystoles (n = 1), acute cholecystitis (n = 1), intervertebral disc protrusion (n = 1), retinal detachment (n = 1) and appendicitis (n = 1); ⁶No grade 3-4 INR laboratory abnormalities were observed;

⁷One patient experienced vomiting, decreased appetite and myalgia (all resolved), plus grade 3 ALT and AST abnormalities (both reversible), and interrupted DUAL treatment for 2 d (patient achieved SVR12). AE: Adverse event; ALT: Alanine transaminase; AST: Aspartate transaminase; INR: International normalized ratio.
