Abstract

Some individuals do not achieve a cure of their hepatitis C virus (HCV) infection due to non-adherence or resistance associated substitutions. Salvage options that are optimised for resistance profiles are essential. We report a 56-year-old Caucasian man with fatigue, depression and confusion in the setting of untreated HCV genotype 3a infection. He received ruzasvir and uprifosbuvir for 12 weeks within a clinical trial. The patient relapsed 4 weeks after the end of treatment and at this time resistance testing showed multiple resistances including a NS5A Y93H mutation. Given that this mutation confers resistance to first line salvage options, sofosbuvir and glecaprevir/pibrentasvir was used for 12 weeks and the patient was cured of HCV infection 12 weeks after the end of treatment. This shows that sofosbuvir and glecaprevir/pibrentasvir is a viable, effective option for second line/salvage therapy of HCV infection in the setting of resistance to NS5A inhibitors with the Y93H mutation.
