Efficacy and Safety of SOF/VEL + RBV and SOF/VEL/VOX for 12 Weeks in HCV Subjects With GT3b and Compensated Cirrhosis

Summary

Direct-acting antiviral agents (DAAs) targeting HCV have revolutionized the treatment of HCV. The efficacy of DAA-based therapy can depend on patient-related factors such as treatment experience, cirrhosis, but also on viral genotype. The high prevalence of genotype 3, which is considered difficult to cure, remains a challenge because many oral DAAs are less effective for this genotype, particularly subtype 3b than for others. Current guidance generally recommends sofosbuvir (SOF)/velpatasvir (VEL) ± ribavirin (RBV), glecaprevir/pibrentasvir and SOF/VEL/voxilaprevir (VOX) as first-line therapy for genotype 3, and an interferon-based regimen - SOF plus pegylated interferon and ribavirin is still recommended as an alternative treatment option. These recommendations are based on clinical data generated in regions where genotype 3a predominates. Our recent study indicated that sofosbuvir plus ribavirin for 24 weeks in subjects with HCV genotype 3 infection resulted in high rates of SVR. However, the SVR12 rate among subjects with genotype 3b was lower than that observed in subjects with genotype 3a infection, particularly among treatment-experienced subjects with cirrhosis. Our study aimed to investigate the efficacy and safety of SOF/VEL plus RBV for 12 weeks or SOF/VEL/VOX for 12 weeks in DAAs treatment naïve HCV subjects with GT3b, compensated cirrhosis in China.
