Media Coverage of this Article

Hepatitis C virus (HCV) is a major global health issue and successful treatment has been associated with a reduction of risk of all-cause mortality. Advancements have been made in HCV treatment through the use of interferon-free regimens. Most trials have been conducted in HCV genotype (GT) 1 and data for interferon-free regimens in GT4 patients are limited. The aim of this study was to evaluate the safety and efficacy of sofosbuvir plus simeprevir in a real-world cohort of HCV GT4 patients with advanced fibrosis.

Patients and Methods
Eighty-seven GT4 treatment-naïve or –Interferon (IFN) ribavirin (RBV) experienced patients treated with sofosbuvir and simeprevir +/- ribavirin (RBV) were enrolled in this cohort study (41% severe fibrosis, 59% cirrhosis).

Patients were 51.7% male, 78.2% IFN/RBV treatment-experienced, and 37.9% received RBV treatment. The overall sustained virologic response at least 12 weeks after treatment (SVR12) rate was 87.4% while patients treated with and without RBV had rates of 87.9% and 87% (p = 0.593), respectively, and patients with advanced fibrosis (F3) and patients with cirrhosis had SVR12 rates of 94.4% and 82.4% (p = 0.087), respectively. SVR12 rates in treatment-naïve patients and in IFN/RBV -experienced patients were 78.9% and 89.7% (p = 0.191), respectively. Treatment failure occurred most commonly in patients with cirrhosis and severe disease. The treatment was well tolerated and no patient died or discontinued treatment due to adverse events.

Sofosbuvir in combination with simeprevir +/- ribavirin in GT 4 HCV patients with advanced fibrosis achieved high SVR12 rates and was well tolerated. RBV did not appear to increase the rate of SVR12.
