Background: Sofosbuvir (SOF), Simeprevir (SMV) and Daclatasvir (DCV) are reimbursed for chronic hepatitis C patients with advanced liver disease (F3, F4) and posttransplant patients in Austria.

Real-life data in these patients are scarce and the optimal duration of treatment is still under debate. The aim of this study was to evaluate the efficacy of SOF based treatment regimens in an Austrian-wide multicenter real world setting of chronic hepatitis C patients with cirrhosis.

Methods: 250 HCV monoinfected patients with cirrhosis (mean age: 56.5 ± 10.6 years, m/f: 167/83, treatment experienced: 161 [64%], prior failure to protease inhibitors: 35 [14%], median platelet count: 98 G/l) who were treated with Sofosbuvir 400 mg/day combined with 60 mg/day Daclatasvir (GT 1, 3, 4; n = 117) or with Simeprevir 150 mg/d (GT 1 and 4; n = 82) or weight based ribavirin (RBV; GT 1 – 4; n = 51) were included. Duration of treatment was at the discretion of the investigator. Viral load was measured after 48 hours, at weeks 1, 2, 3, 4 and then every 4 weeks until the end of treatment by Abbott RealTime HCV quantitative assay (lower limit of quantification [LLOQ]: 12IU/ml) or by Roche COBAS AmpliPrep/COBAS TaqManHCV quantitative assay, Version 2 (LLOQ: 15IU/ml).

Results: HCV-RNA dropped by a mean log of 2.91 and 3.54 after 48 hours and 7 days, respectively. At weeks 4, 8, 12, and 16 of treatment, 22%, 61%, 80%, and 90% of patients had undetectable HCV RNA (target not detected), respectively. Of the 155 patients who have reached end of treatment (treatment duration: 12 weeks: n = 50, 16 weeks: n = 15, 20 weeks: n = 3, 24 weeks: n = 87) 107 reached follow-up week 4 (97 SVR4 [90.6%]), 10 patients relapsed: 6 after SOF/RBV, 2 after SOF/SMV, 1 after SOF/DCV. 2 patients discontinued therapy due to psychiatric adverse events and 2 died during treatment (decompensation and sepsis).

Conclusions: IFN-free treatment regimens containing SOF are highly effective and well tolerated in patients with cirrhosis. Determination of on-treatment response may help to optimize treatment duration in patients with advanced liver disease.
