Brief Summary:
Hepatitis C virus (HCV) infection is common in patients receiving hemodialysis. The uptake of antiviral therapy for these patients is limited in the era of interferon (IFN) plus ribavirin (RBV), probably because the sustained virologic response (SVR) rates are low and the risk of treatment-related adverse events (AEs) are high. In the era of IFN-free direct acting antiviral agents (DAAs), several studies have indicated high rates of SVR and excellent safety profiles to treat patients with severe renal impairment. With regard to ombitasvir/paritaprevir/ritonavir plus dasabuvir (PrOD) treatment, a phase 2 study (RUBY-1) study has shown 90% of SVR in treatment-naive HCV-1 patients with chronic kidney disease (CKD) stage 4 or 5. Among the HCV-1b patients, who received PrOD for 12 weeks, all 7 patients achieved SVR. Although the data confirmed the excellent safety and efficacy in HCV-1b patients with severe renal impairment, the patient number was small and the data with regard to treatment-experienced patients was lacking. Therefore, we aimed to evaluated the safety and efficacy of ProD for 12 weeks in treatment-naive and treatment-experienced HCV-1b patients receiving hemodialysis.
