Ombitasvir/ Paritaprevir/ Ritonavir

Objective: Objective: Ombitasvir/paritaprevir/ritonavir (OMV/PTV/r) + ribavirin (RBV) combination improved the efficacy, safety, and tolerability of the treatment of chronic hepatitis C virus (HCV) genotype 4 infection. We described the effectiveness and safety of OMV/PTV/r + RBV therapy in patients with genotype 4 infection. Materials and Methods: In this prospective cohort study, HCV genotype 4-infected patients treated with OMV/PTV/r + RBV (n=55) who were registered in a national database were included. Study patients were treatment-naive or interferon plus RBV-experienced with or without compensated cirrhosis. Demographic, clinical and virological data were analyzed. Details of clinical and laboratory adverse events (AEs) were recorded.Results: The mean age of the patients was 55.2, and 52.7% were male. The majority of patients were non-cirrhotic (81.8%), and 69.1% were treatment-naive. The HCV RNA level was below 800.000 IU/mL in 16 of the cases. Seventy-eight percent of the patients had an underlying disease. SVR12 rate was 98% in all patients. One patient had virological failure. HCV RNA was undetectable at treatment week 4 in 77.6%, at treatment week 8 in 100%, and at end of treatment in 98%. The SVR12 rates were 100% and 88.9% for those without or with compensated cirrhosis (p= 0.176). Rates of AEs and AEsassociated treatment discontinuation were 69.1% and 3.6% in the patients, respectively.Conclusion: The OBV/PTV/r + RBV combination was found to have high efficacy and safety profile in the patients with chronic HCV genotype 4 infection.
