Sofosbuvir plus velpatasvir treatment for hepatitis C virus in patients with decompensated cirrhosis: a Japanese real-world multicenter study.

Background: Real-world data on the efficacy and safety of sofosbuvir plus velpatasvir (SOF/VEL) treatment for patients with hepatitis C virus (HCV)-related decompensated cirrhosis are limited in Japan.
Methods: A total of 190 patients with compensated (108) or decompensated (82) cirrhosis who initiated direct-acting antiviral (DAA) treatment between February 2019 and August 2019 were enrolled. Sustained virologic response (SVR) was defined as undetectable serum HCV-RNA at 12 weeks after the end of treatment (EOT).
Results: The SVR12 rates were 92.6% in patients with compensated cirrhosis and 90.2% in patients with decompensated cirrhosis (p = 0.564), and the treatment completion rates were 98.1% and 96.3%, respectively (p = 0.372). In patients with decompensated cirrhosis, 3 patients discontinued treatment and 2 patients died because of liver-related events. In patients with decompensated cirrhosis with SVR12, 50% of patients with Child-Pugh class B at baseline showed improvement to class A at SVR12, and 27% and 9% of patients with Child-Pugh class C at baseline showed improvement to class B and class A at SVR12, respectively. Patients who achieved SVR12 showed elevated serum albumin levels at the EOT, which were further elevated at SVR12, but no elevated serum albumin levels after the EOT were observed in patients with baseline serum albumin levels less than 2.8 g/dl.
Conclusions: Real-world efficacy of SOF/VEL treatment for patients with decompensated cirrhosis was similar to Japanese phase 3 study, although treatment discontinuation and death related to liver disease occurred. In patients with poor hepatic reserve, whether it improves continuously after viral clearance requires further evaluation.
