Simeprevir and daclatasvir for 12 or 24 weeks in treatment-naïve patients with hepatitis C virus genotype 1b and advanced liver disease

Background & Aims: We investigated the efficacy and safety of simeprevir plus daclatasvir in treatment-naïve patients with chronic, genotype 1b hepatitis C virus infection and advanced liver disease, excluding patients with pre-defined NS5A resistance-associated substitutions. Methods: This phase II, open-label, single-arm, multicentre study included patients aged ≥18 years with advanced fibrosis or compensated cirrhosis (METAVIR F3/4). Patients with NS5A-Y93H or L31M/V resistance-associated substitutions at screening were excluded. Simeprevir (150 mg)+daclatasvir (60 mg) once daily was administered for 12 or 24 weeks; treatment could be extended to 24 weeks prior to or at the Week 12 v…

Evolution of HCV patient characteristics and DAA regimens in the German Hepatitis C Registry (DHC-R) in 2014 and 2015

 The urgent need in HCV-infected patients with liver disease mandated the rapid implementation of IFN-free DAA combination therapies following their regulatory approval in 2014 and 2015 without full knowledge of the optimal combinations and regimens. Investigating the evolution of the DAA utilization patterns and treatment outcomes could provide learnings for future situations. This was an analysis of a prospective observational database from the German Hepatitis C Registry (DHC-R) covering a period from May 2014 to September 2015. Adult patients had evidence of chronic HCV GT1 or GT4 infection and were treated with an IFN-free combination regimen of simeprevir (SMV) + sofosbuvir (SOF) or o…

Efficacy of a 12-Week Simeprevir Plus Peginterferon/Ribavirin (PR) Regimen in Treatment-Naïve Patients with Hepatitis C Virus (HCV) Genotype 4 (GT4) Infection and Mild-To-Moderate Fibrosis Displaying Early On-Treatment Virologic Response

Background HCV GT4 accounts for up to 20% of HCV infections worldwide. Simeprevir, given for 12 weeks as part of a 24- or 48-week combination regimen with PR is approved for the treatment of chronic HCV GT4 infection. Primary study objectives were assessment of efficacy and safety of simeprevir plus PR in treatment-naïve patients with HCV GT4 treated for 12 weeks. Primary efficacy outcome was sustained virologic response 12 weeks post-treatment (SVR12). Additional objectives included investigation of potential associations of rapid virologic response and baseline factors with SVR12. Methods This multicentre, open-label, single-arm study (NCT01846832) evaluated efficacy and safety of simepre…

An Open-Label Trial of 12-Week Simeprevir plus Peginterferon/Ribavirin (PR) in Treatment-Naïve Patients with Hepatitis C Virus (HCV) Genotype 1 (GT1)

Background: Shortening duration of peginterferon-based HCV treatment reduces associated burden for patients. Primary objectives of this study were to assess the efficacy against the minimally acceptable response rate 12 weeks post-treatment (SVR12) and safety of simeprevir plus PR in treatment-naïve HCV GT1 patients treated for 12 weeks. Additional objectives included the investigation of potential associations of rapid viral response and baseline factors with SVR12. Methods: In this Phase III, open-label study in treatment-naïve HCV GT1 patients with F0-F2 fibrosis, patients with HCV-RNA 12-week regimen. Conclusions: Overall SVR12 rate (66%) was below the target of 80%, indicating that sho…

P0792 : Baseline factors associated with increased SVR rates in 123 treatment-naïve chronic HCV genotype 1 patients treated with a shortened 12-week simeprevir plus pegylated interferon and ribavirin regimen: a multivariate analysis

PTH-137 Safety and efficacy of simeprevir (SMV) plus PEG-IFN/RBV in treatment-naÏve chronic hepatitis c genotype 1 patients eligible for 12 weeks of treatment

Introduction HPC3014 is a Phase 3, open-label study to assess if response to SMV+Peg-IFN/RBV at Week 2 can allow shortening of treatment to 12 weeks, irrespective of baseline and on-treatment factors. Method Treatment-naive chronic HCV G1-infected patients with no-to-moderate fibrosis (METAVIR F0–F2) were recruited. In patients with HCV-RNA ® Taqman ® lower limit of quantification: 25 IU/mL, lower limit of detection: 15 IU/mL]) at Week 2 and undetectable at Weeks 4 and 8, all treatments were stopped at Week 12 (12-week group). If these criteria were not met, Peg-IFN/RBV was continued to Week 24 (in one case extended to Week 48). Results 123/163 (76%) patients treated were eligible for the 1…
