Background: Data are limited regarding the effectiveness and safety of generic velpatasvir plus sofosbuvir (VEL/SOF) for hepatitis C virus (HCV) in patients with or without human immunodeficiency virus (HIV) coinfection.
Aim: To evaluate the effectiveness and safety of generic VEL/SOF-based therapy for HCV infection in patients with or without HIV coinfection in Taiwan.
Methods: Sixty-nine HIV/HCV-coinfected and 159 HCV-monoinfected patients receiving 12 weeks of generic VEL/SOF with or without ribavirin (RBV) for HCV were prospectively enrolled. The anti-viral responses and the adverse events (AEs) were compared between the two groups. The characteristics potentially related to sustained virological response 12 weeks off therapy (SVR12 ) were analysed.
Results: The SVR12 was achieved in 67 HIV/HCV-coinfected patients (97.1%; 95% CI: 90.0%-99.2%) and in 156 HCV-monoinfected patients (98.1%; 95% CI: 94.6%-99.4%) receiving VEL/SOF-based therapy, respectively. The SVR12 rates were comparable between HIV/HCV-coinfected and HCV-monoinfected patients, regardless of pre-specified baseline characteristics. One hundred twenty-two (53.5%) and seven (3.1%) patients had baseline resistance-associated substitutions (RASs) in HCV NS5A and NS5B regions, but the SVR12 rates were not affected by the presence or absence of RASs. One (1.4%) and five (3.1%) patients in the HIV/HCV-coinfected and HCV-monoinfected groups had serious AEs. No patient died or discontinued treatment due to AEs. The eGFR remained stable throughout the course of treatment in HIV/HCV-coinfected patients receiving anti-retroviral therapy containing tenofovir disoproxil fumarate (TDF).
Conclusions: Generic VEL/SOF-based therapy is well-tolerated and provides comparably high SVR12 rates for HCV infection in patients with and without HIV coinfection.
