Ledipasvir/Sofosbuvir Is Effective for Relapsed Genotype 1b Hepatitis C Virus Patients after Achieving a Sustained Virological Response at Post-treatment Week 12 with Glecaprevir/Pibrentasvir.

A patient with genotype 1b chronic hepatitis C virus who had been treated with pegylated interferon and ribavirin (RBV) was treated with glecaprevir/pibrentasvir (GLE/PIB) for 12 weeks. A sustained virological response at post-treatment week 12 (SVR12) was achieved, but relapse occurred approximately 31 weeks after the end of treatment. The patient had a history of allergy to RBV and was treated with ledipasvir/sofosbuvir (LDV/SOF), achieving SVR12 and remaining hepatitis C virus-negative until 24 weeks after the completion of treatment. LDV/SOF can thus be a secondary treatment for GLE/PIB.
