Margusino-Framiñán L, Cid-Silva P, Rotea-Salvo S, et al. Effectiveness and safety of sofosbuvir/velpatasvir ± ribavirin vs glecaprevir/pibrentasvir in genotype 3 hepatitis C virus infected patients. Euro. J. Hosp. Pharm. 2020; 27(e1):e41-e47.
[Abstract] Objectives. Sofosbuvir/velpatasvir±ribavirin (SOF/VEL±RBV) and glecaprevir/pibrentasvir (GLE/PIB) are the drug combinations of choice for treating individuals with genotype 3 hepatitis C virus (G3-HCV) infection. The objective of this study was to evaluate the effectiveness and safety of SOF/VEL±RBV compared with GLE/PIB for treating G3-HCV infection under routine clinical practice conditions. Methods. We conducted a prospective observational cohort study of individuals with G3-HCV infection who initiated treatment with SOF/VEL +/-RBV or GLE/PIB between April 2017 and July 2018. Prisoners and children were excluded. The outcome variable of effectiveness was sustained virological response 12 weeks after completing treatment (SVR12). The safety variable was withdrawal secondary to severe adverse events (SAEs). Covariates included sex, age, HIV co-infection, previous liver transplant, cirrhosis, hepatic fibrosis and previous antiviral treatment. Statistical significance was calculated using Fisher’s exact test or the Mann–Whitney U-test. Results. A total of 76 patients were included in the analysis, of whom 46 were treated with SOF/VEL±RBV and 30 were treated with GLE/PIB. No baseline differences were observed between treatment groups with respect to age, sex, HIV co-infection, fibrosis stage, cirrhosis and previous antiviral treatment. Of the patients treated with SOF/VEL±RBV and GLE/PIB, 95.7% and 96.7% reached SVR12, respectively (P=0.7). Of patients with and without cirrhosis, 83.3% and 98.4% reached SVR12, respectively (P=0.09). Of the patients with low-grade hepatic fibrosis (F0-2) and advanced fibrosis (F3-4), 100% and 85.7% reached SVR12, respectively (P=0.03). In treatment-naïve and treatment-experienced patients, 95.7% and 100% reached SVR12, respectively (P=0.57), without significant differences independent of the treatment group (P=0.28 for SOF/VEL±RBV; P=0.18 for GLE/PIB). The incidence of AEs was 21.1% (95% CI 11.3% to 30.9%). None of the patients developed an SAE or required antiviral treatment withdrawal. Conclusions. SOF/VEL±RBV or GLE/PIB are safe and effective for treating G3-HCV-infections, with a lower effectiveness in patients with advanced fibrosis F3-4.
