Abstract
Background
Data regarding the real-world effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) for East Asian patients with chronic hepatitis C virus (HCV) infection and compensated liver disease are limited. We evaluated the performance of SOF/VEL for 12 weeks for HCV-infected patients with compensated liver disease in a large real-world cohort in Taiwan.
Methods
Between July 2019 and March 2020, 1880 HCV-infected patients with compensated liver disease who received SOF/VEL 400/100 mg once daily for 12 weeks were included at 15 academic centers in Taiwan. The sustained virologic response at off-treatment week 12 (SVR12) was assessed for evaluable (EP) and per-protocol populations (PP). The tolerance was also reported.
Results
The SVR12 rates by EP and PP analyses were 95.6% [1798 of 1880 patients; 95% confidence interval (CI) 94.6–96.5%] and 99.3% (1798 of 1811 patients; 95% CI 98.8–99.6%), respectively. Among 82 patients who failed to achieve SVR12, 13 (15.9%) were attributed to virologic failures. The SVR12 rates were comparable regardless of baseline characteristics. A total of 1859 (98.9%) patients completed 12-week SOF/VEL treatment. Four (0.2%) patients discontinued treatment due to adverse events (AEs). All patients with serious AEs or deaths were judged not related to SOF/VEL. The AEs occurring in ≥ 10% included headache (16.8%), fatigue (16.2%), nausea (11.8%), and insomnia (11.1%). Nine (0.5%) and 2 (0.1%) patients had grade 3 total bilirubin and alanine aminotransferase elevations.
Conclusions
SOF/VEL for 12 weeks is efficacious and well-tolerated by chronic HCV-infected patients with compensated liver disease in Taiwan.
