Effectiveness and safety of SOF/VEL containing rescue therapy in treating chronic HCV-GT4 patients previously failed NS5A inhibitors-based DAAs

NS5A inhibitors are an important option for treating chronic HCV-GT4 patients. Retreatments after NS5A-based DAAs failure are limited. We aimed to determine the effectiveness and safety of SOF/VEL-containing regimens for HCV retreatment after NS5A-regimen failure. Prospective cohort study assessing the efficacy and safety of retreatment with SOF/VEL in addition to either voxilaprevir or ribavirin in patients who had failed previous NS5A-based DAA treatment. The primary outcome was SVR12. Safety and tolerability data were collected. One hundred fifty patients were included. The mean age was 53 years, 64
