Real-world effectiveness and safety of sofosbuvir/velpatasvir and ledipasvir/sofosbuvir hepatitis C treatment in a single centre in Germany.

ABSTRACT: BACKGROUND:Newer direct-acting antiviral therapies are increasingly becoming the therapy of choice in patients with hepatitis C virus (HCV) infection. Here, we report the safety and effectiveness of sofosbuvir/velpatasvir (SOF/VEL) and ledipasvir/sofosbuvir (LDV/SOF) in real-world cohorts in Germany. METHODS:Patients initiated on SOF/VEL 12 weeks or LDV/SOF 8, 12 or 24 weeks regimens in a single German centre were included in this study. Data on treatment outcomes and adverse events (AE) were analysed in patients with available sustained virologic response 12 weeks after cessation of treatment (SVR12) information overall and by subgroups. RESULTS:This study included 115 patients who received SOF/VEL from July-2016 to July-2017, and 249 patients who received LDV/SOF from November-2014 to September-2015. Overall, SVR12 was achieved in 99% of patients on SOF/VEL ± ribavirin 12 weeks independent of HCV genotype, treatment history, or cirrhosis status, and in 96% of patients treated with LDV/SOF 8 weeks or LDV/SOF ± ribavirin 12 or 24 weeks. In genotype 1 treatment-naïve, non-cirrhotic patients, ?99% achieved SVR12 across SOF/VEL and LDV/SOF regimens. Likewise, 100% of genotype 3-cirrhotic patients on SOF/VEL ± ribavirin regimens achieved SVR12. Grade 3/4 AE were reported in 13 (5.2%) patients on LDV/SOF and in 1 (<1%) patient on SOF/VEL. CONCLUSION:Overall, SOF/VEL and LDV/SOF achieved high SVR rates in a broad patient population. We showed the effectiveness of SOF/VEL as a pan-genotypic regimen, and regardless of treatment history or cirrhosis status. Use of such therapies improves outcomes and contributes towards the global efforts to eradicate HCV.

Project description:IntroductionPangenotypic direct-acting antivirals are expected to cure hepatitis C virus (HCV) in more than 95% of treated patients. However, data on the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) in Taiwan are limited. This study aims to characterize the patient population in the nationwide Taiwan Association for the Study of the Liver (TASL) HCV Registry and evaluate treatment outcome in Taiwanese patients receiving SOF/VEL.MethodsThis study was a retrospective-prospective, observational, multicenter, real-world analysis. Adults with chronic hepatitis C were treated with SOF/VEL 400/100 mg ± ribavirin for 12 weeks. The primary outcome was sustained virologic response 12 weeks after end of therapy (SVR12). Factors associated with not achieving SVR12 were evaluated using logistic regression and covariate analysis. Safety was also assessed.ResultsIn total, 3480 patients were included: 86.8% genotype 1/2, 2.8% genotype 3, 0.1% genotype 4/5, 9.6% genotype 6; unclassified, 0.8%; 12.2% compensated cirrhosis; 3.3% decompensated cirrhosis; and 15.8% chronic kidney disease. Overall SVR12 rate was 99.4% (genotype 1, 99.5%; genotype 2, 99.4%; genotype 3, 96.9%; genotype 4, 100%; genotype 6, 99.7%). SVR12 rates among patients with compensated cirrhosis, decompensated cirrhosis, and chronic kidney disease stages 4-5 were 99.5%, 100%, and 100%, respectively. There were 21 patients (0.6%) who did not achieve SVR12. Factors associated with failure were treatment adherence below 60%, high viral load, and genotype 3 (p < 0.001, p = 0.028, and p = 0.001, respectively). Adverse events occurred in 10% of patients; 0.6% were serious and one was related to treatment. Treatment discontinuation occurred in 0.3% of patients; none were treatment related. The estimated glomerular filtration rate remained stable throughout treatment and follow-up, regardless of baseline values and cirrhosis status.ConclusionSOF/VEL was highly effective and well tolerated in Taiwanese patients, irrespective of viral genotype, liver disease severity, and comorbidities.

Project description:Background & aimsVoxilaprevir/velpatasvir/sofosbuvir (VOX/VEL/SOF) is highly effective for re-treatment of direct-acting antiviral (DAA)-experienced patients with chronic HCV infection. In the present study, predictors of virologic treatment response were analyzed in an integrative analysis of three large real-world cohorts.MethodsConsecutive patients re-treated with VOX/VEL/SOF after DAA failure were enrolled between 2016 and 2021 in Austria, Belgium, Germany, Italy, Spain and Switzerland.ResultsA total of 746 patients were included: median age was 56 (16-88) years and 77% were male. Most patients were infected with HCV genotype 1 (56%) and 3 (32%). 86% of patients carried resistance-associated substitutions in the NS3, NS5A or NS5B regions. Overall, 95.4% (683/716) of patients achieved a sustained virologic response. Treatment effectiveness was significantly affected by advanced liver disease (p <0.001), hepatocellular carcinoma (p <0.001), higher baseline ALT levels (p = 0.02), HCV genotype 3 (p <0.001), and prior VEL/SOF treatment (p = 0.01). In a multivariate analysis, only HCV genotype 3, hepatocellular carcinoma and cirrhosis turned out to be independent predictors of treatment failure. Resistance-associated substitutions, as well as the presence of rare genotypes, did not impact treatment outcome. The effectiveness of rescue therapy with glecaprevir/pibrentasvir and SOF, with or without ribavirin, for 12 to 24 weeks was found to be high (100%).ConclusionsInfection with HCV genotype 3, the presence of liver cancer and cirrhosis are independently associated with failure of VOX/VEL/SOF re-treatment. It is unclear whether the addition of ribavirin and/or extension of treatment duration may be effective to avoid virologic relapse on VOX/VEL/SOF. However, rescue treatment with glecaprevir/pibrentasvir+SOF seems to be effective.Impact and implicationsRepresentative data on the effectiveness of voxilaprevir/velpatasvir/sofosbuvir (VOX/VEL/SOF) in clinical practice are still scarce and the collection of a larger number of patients with difficult-to-treat cofactors including the assessment of resistance-associated substitution profiles is required before more specific recommendations for optimal re-treatment in these patients can be given. Thus, we aimed to analyze treatment effectiveness and predictors of virologic response to VOX/VEL/SOF in an integrative analysis of three large real-word cohorts. The study results, derived from a multicenter cohort consisting of 746 patients, demonstrated that re-treatment with VOX/VEL/SOF is an effective salvage therapy associated with an overall per protocol sustained virologic response rate of 95%. Hepatocellular carcinoma onset, cirrhosis and HCV genotype 3 were identified as independent negative predictors of treatment response, whereas resistance-associated substitutions, as well as rare genotypes and chimera, did not impact sustained virologic response rates following re-treatment with VOX/VEL/SOF.

Project description:IntroductionReal-world data regarding the impact of hepatic fibrosis on the effectiveness of sofosbuvir/velpatasvir (SOF/VEL) treatment is limited in the Asian population.MethodsWe analyzed data for all 823 patients with hepatitis C virus treated with SOF/VEL from June 2019 to September 2020 at Chang Gung Memorial Hospital in Chiayi, Taiwan. The degree of fibrosis was determined using the fibrosis-4 (FIB-4) index, with advanced fibrosis or cirrhosis defined as a FIB-4 score of > 3.25. The primary treatment outcome was the rate of sustained virologic response 12 weeks after treatment cessation (SVR). Adverse events (AEs) were also evaluated.ResultsSVR rates did not significantly differ (p > 0.05) between patients with FIB-4 scores of ≤ 3.25 and those with scores of > 3.25. In the per protocol analysis, 99.2% (593/598) of the FIB-4 ≤ 3.25 group and 100% (172/172) of the FIB-4 > 3.25 group achieved SVR; in the evaluable population analysis, 93.4% (593/635) of the FIB-4 ≤ 3.25 group and 91.5% (172/188) of the FIB-4 > 3.25 group achieved SVR. Five patients with FIB-4 scores of ≤ 3.25 did not attain SVR: two relapsed and three had no response. The most common AEs were comparable (p > 0.05) for the FIB-4 ≤ 3.25 group and the FIB-4 > 3.25 group and included abdominal discomfort (4.4% vs. 5.9%), fatigue (4.1% vs. 5.9%), and skin itching (3.6% vs. 3.2%). Laboratory abnormalities were more common in the FIB-4 > 3.25 group (p < 0.001). Six patients with FIB-4 scores of > 3.25 had total bilirubin elevation > 3 × the upper normal limit (UNL). Alanine transaminase elevation > 5 × the UNL was observed in two patients with FIB-4 scores of ≤ 3.25 and one patient with a FIB-4 score of > 3.25. No AEs resulted in treatment discontinuation.ConclusionsSOF/VEL treatment is well tolerated and achieves high SVR rates for patients of Taiwanese ethnicity with HCV, regardless of cirrhosis status.
