In routine clinical practice, few physicians use early viral kinetics to guide HCV dual therapy treatment decisions

Abstract Background & Aims PROPHESYS is a large, multinational, non-interventional prospective cohort study of chronic hepatitis C patients treated with peginterferon alfa/ribavirin. This subanalysis assesses rates of premature treatment discontinuation stratified by on-treatment virological response (VR). Methods This PROPHESYS subanalysis is restricted to treatment-naive, hepatitis C virus (HCV) genotype (G)1/2/3 mono-infected patients who received peginterferon alfa-2a (40KD)/ribavirin with intended treatment duration of 48 (G1) or 24 weeks (G2/3). Early virological responses were classified into four mutually exclusive categories [rapid VR (RVR), complete early VR (cEVR), partial EVR (pEVR), no RVR/EVR], using standard criteria. Results The likelihood for shortening treatment owing to good efficacy was highest among patients with an RVR and HCV RNA ≤400 000 IU/ml (G1 10.0%; G2/3 5.8%) whereas for poor efficacy, it was highest in G1 non-RVR/EVR patients with HCV RNA >400 000 IU/ml (56.6%). Factors significantly associated with early treatment discontinuation as a result of good efficacy in G1 patients included RVR vs. no RVR/EVR and, at baseline, lower HCV RNA, lower FIB-4 score, HCV infection via injection drug use. For G2/3 patients, factors included lower baseline HCV RNA and G2 vs. G3 infection. Most patients started with the recommended peginterferon alfa-2a dose, but a high proportion received a higher-than-recommended ribavirin dose. Conclusions Despite international guidelines, few physicians used early viral kinetics to abbreviate treatment. Therefore, relatively few patients with an RVR and low baseline HCV RNA abbreviated treatment. In addition, there were deviations in ribavirin starting doses, suggesting that physicians tailor treatment according to local guidelines or previous experience

HCVerso2: a phase III study of faldaprevir plus deleobuvir and ribavirin for chronic HCV genotype 1b infection in treatment naïve patients including those ineligible for pegylated interferon

peer reviewedIn treatment-naïve, non-cirrhotic patients with HCV GT1b infection, faldaprevir + deleobuvir + ribavirin for 16 or 24 w resulted in comparable SVR 12 rates (76% vs 82%) with similar tolerability profiles. Patients with cirrhosis achieved SVR 12 of 74% (24w). The adjusted SVR rates for 16 or 24w in patients with or without cirrhosis were significantly higher than historical control

Global real-world evidence of sofosbuvir/velpatasvir as simple, effective HCV treatment: Analysis of 5552 patients from 12 cohorts

Background and aims: Achieving sustained virological response (SVR; cure) in hepatitis C patients using a simple regimen is key to making elimination by 2030 possible. In the largest real-world analysis to date, the effectiveness of pangenotypic, panfibrotic, single-tablet, sofosbuvir/velpatasvir (SOF/VEL) once-daily for 12 weeks was assessed in 12 clinical real-world cohorts from various geographical areas, settings and treatment practices. Factors affecting risk of not achieving SVR were assessed. Methods: Adults treated with SOF/VEL 400/100 mg, without ribavirin, were included. All HCV patients reaching Week 12 or 24 post-treatment were assessed for SVR12/24. Factors associated with not achieving SVR12/24 for virological reasons were evaluated using logistic regression analysis. Results: Overall, 5552 patients were included: 13.3% treatment-experienced; 20.7% compensated cirrhotic; 30.2% genotype 1; 29.5% genotype 2; 32.9% genotype 3; 4.7% genotype 4; 3.7% HIV coinfection; 13.4% current/former intravenous drug use. Of the 5196 patients evaluated for effectiveness, 98.9% achieved SVR12/24. High SVR12/24 rates occurred in all genotypes including genotype 3 (98.3%; 1649/1677) and in those with compensated cirrhosis (97.9; 1055/1078). Only 55 patients did not achieve SVR12/24 due to a virological reason; the only factor statistically significantly associated with an increased risk of not achieving SVR12/24 was compensated cirrhosis (P =.002). Overall, 6% (332/5552) of patients did not achieve SVR12/24 for non-virological reasons (67% lost to follow-up; 26.5% early treatment discontinuation). Conclusions: In this large cohort, representative of clinical practice, a simple 12-week regimen of SOF/VEL without ribavirin resulted in high SVR12/24 rates in diverse patient populations, even among those with compensated cirrhosis. © 2020 The Authors.
