Effectiveness and safety of sofosbuvir/velpatasvir ± ribavirin vs glecaprevir/pibrentasvir in genotype 3 hepatitis C virus infected patients.

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. 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. 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. 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.

Real-world effectiveness and safety of sofosbuvir/velpatasvir and glecaprevir/pibrentasvir for genotype 6 chronic hepatitis C.

Hepatitis C virus (HCV) genotype 6 mainly distributes in Southeast Asia and South China. Because of the low prevalence in developed countries, optimal treatment for HCV genotype 6 in real-world setting remains to be determined. We aimed to evaluate the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) and glecaprevir/pibrentasvir (GLE/PIB) for patients with HCV genotype 6 infection in Taiwan. A total of 286 patients with chronic hepatitis C (CHC) genotype 6, 161 receiving 12-week SOF/VEL and 125 receiving 8-week GLE/PIB, were enrolled. All patients were followed up for 12 weeks after treatment completion. Demographic information, HCV viral load (VL), profiles of lipid and sugar, and adverse events were recorded and reviewed. Sustained virological response (SVR) rates of SOF/VEL and GLE/PIB evaluated by intention-to-treat analysis were 99.38% and 100%, respectively. SVR achieved 100%, regardless of cirrhosis or viral load (cutoff: 6 MIU/mL), of both regimens by per-protocol analysis. Skin itching was the most common adverse event, with an overall incidence of 6.64% which was more prevalent in GLE/PIB (12.0%) than SOF/VEL (2.48%). A significant decrease in the estimated glomerular filtration rate was observed in patients receiving SOF/VEL but not in those receiving GLE/PIB at the time of SVR. No patient discontinued treatment due to adverse event. The high SVR and excellent safety of SOF/VEL and GLE/PIB in real-world setting reveals that the two DAA regimens are favorable options for treatment of HCV genotype 6 in Taiwan and Asia.

Real-life effectiveness of sofosbuvir/velpatasvir/voxilaprevir in hepatitis C patients previously treated with sofosbuvir/velpatasvir or glecaprevir/pibrentasvir.

Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is the recommended rescue therapy for patients with chronic hepatitis C infection who fail direct-acting antivirals (DAAs). Data are limited on the effectiveness of this treatment after the current first-line therapies. Our aim was to analyse the effectiveness and safety of SOF/VEL/VOX among patients failing sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). Retrospective multicentre study (26 Spanish hospitals), including chronic hepatitis C patients unsuccessfully treated with SOF/VEL or GLE/PIB, and retreated with SOF/VEL/VOX ± ribavirin for 12 weeks between December 2017 and December 2022. In total, 142 patients included: 100 (70.4%) had failed SOF/VEL and 42 (29.6%) GLE/PIB. Patients were mainly men (84.5%), White (93.9%), with hepatitis C virus genotype (GT) 3 (49.6%) and 47.2% had liver cirrhosis. Sustained virological response (SVR) was evaluated in 132 patients who completed SOF/VEL/VOX and were followed 12 weeks after end of treatment; 117 (88.6%) achieved SVR. There were no significant differences in SVR rates according to initial DAA treatment (SOF/VEL 87.9% vs. GLE/PIB 90.2%, p = 0.8), cirrhosis (no cirrhosis 90% vs. cirrhosis 87.1%, p = 0.6) or GT3 infection (non-GT3 91.9% vs. GT3 85.5%, p = 0.3). However, when considering the concurrent presence of SOF/VEL treatment, cirrhosis and GT3 infection, SVR rates dropped to 82.8%. Ribavirin was added in 8 (6%) patients, all achieved SVR. SOF/VEL/VOX is an effective rescue therapy for failures to SOF/VEL or GLE/PIB, with an SVR of 88.6%. Factors previously linked to lower SVR rates, such as GT3 infection, cirrhosis and first-line therapy with SOF/VEL were not associated with lower SVRs.

Real-world effectiveness of direct-acting antiviral agents for chronic hepatitis C patients with genotype-2 infection after completed treatment.

Chronic hepatitis C (CHC) is a major cause of cirrhosis, hepatocellular carcinoma (HCC), and mortality. Eliminating hepatitis C virus (HCV) can greatly improve long-term outcomes. Several direct-acting antiviral agents (DAAs), including sofosbuvir (SOF) plus different NS5A inhibitors, as well as non-SOF-based DAAs, including glecaprevir/pibrentasvir (GLE/PIB), have been approved for treating CHC genotype-2 (GT-2) patients in Taiwan. However, there is limited real-world effectiveness data regarding these different regimens. Thus, we aimed to evaluate the real-world efficacy in CHC GT-2 patients who underwent these DAA regimens. We retrospectively enrolled CHC GT-2 patients who were treated with SOF-based DAAs or GLE/PIB at a single medical center. A total of 704 enrolled patients were treated with either SOF + ribavirin (RBV), SOF/daclatasvir (DCV) ± RBV, SOF/ledipasvir (LDV) ± RBV, SOF/velpatasvir (VEL) ± RBV, or with GLE/PIB. The overall sustained virological response (SVR) rate was 97.9%. The SVR rate was significantly lower in the SOF + RBV group (95.6%) than in the non-SOF + RBV (98.9%) group, especially compared to the SOF/DCV (100%) and GLE/PIB groups (99.5%). Among patients treated with SOF + RBV, cirrhotic patients had significantly lower SVR rates than noncirrhotic patients (89.4% vs 98.2%). Multivariate analysis showed that patients with a younger age, hepatitis B virus coinfection, baseline cirrhosis, or those who received SOF + RBV were less likely to achieve SVR. In conclusion, for CHC GT-2 patients, SOF in combination with DCV, LDV, or VEL, as well as GLE/PIB, achieved similar high efficacies, regardless of cirrhosis, treatment experience, or chronic kidney disease status. Therefore, the use of DAA therapy to eradicate HCV should not be delayed in these populations.
