BACKGROUND Telaprevir in combination with peginterferon and ribavirin is a promising advancement in chronic hepatitis C treatment. However, the safety, tolerability, pharmacokinetics and antiviral profiles of telaprevir alone beyond 2 weeks have not been studied. METHODS In a phase 1b study in Japan, 10 treatment-naïve patients infected with hepatitis C virus genotype 1b with high viral load ...
BACKGROUND In patients with genotype 1 chronic hepatitis C infection, telaprevir (TVR) in combination with peginterferon and ribavirin (PR) significantly increased sustained virologic response (SVR) rates compared with PR alone. However, genotypic changes could be observed in TVR-treated patients who did not achieve an SVR. METHODS Population sequence analysis of the NS3•4A region was perform...
UNLABELLED Background and rationale. The REPLACE study (NCT01571583) investigated telaprevir-based triple therapy in patients who have recurrent genotype 1 hepatitis C virus (HCV) infection following liver transplantation and are on a stable immunosuppressant regimen of tacrolimus or cyclosporin A. Patients received telaprevir 750 mg 8-hourly with pegylated interferon 180 ?g weekly and ribavir...
INTRODUCTION When co-administered with interferon and ribavirin, the prescription drug telaprevir significantly improves treatment response in patients with chronic hepatitis C virus (HCV) infection. Its use, however, also increases the likelihood of adverse effects that may lead to discontinuation of treatment. Cutaneous adverse effects are particularly common. OBJECTIVE To determine the fre...
23 24 Purpose: Telaprevir is a hepatitis C virus protease inhibitor that is both a substrate and 25 an inhibitor of CYP3A. Amlodipine and atorvastatin are both substrates of CYP3A and 26 are amongst the drugs most frequently used by patients with hepatitis C. This study was 27 conducted to examine the effect of telaprevir on atorvastatin and amlodipine 28 pharmacokinetics (PK). 29 Methods: This...
BACKGROUND Boceprevir and telaprevir have recently showed dramatically better treatment outcomes than conventional PEGylated interferon plus ribavirin for the treatment of hepatitis C virus genotype 1, but the average cost per patient is unknown. METHODS In the UK context, we performed a budget impact analysis to estimate the average per patient cost of adding boceprevir or telaprevir to PEGy...
PURPOSE Chronic hepatitis C virus (HCV) is a major problem affecting up to 170 million people worldwide. Two protease inhibitors have recently been approved that will revolutionize treatment. Our objective was to summarize and evaluate the literature pertaining to the pharmacokinetics of boceprevir and telaprevir, in order to provide clinicians with insight into the management of actual and pot...
AIMS The aim was to evaluate the effect of boceprevir and telaprevir on dolutegravir pharmacokinetics (PK); the effect of dolutegravir on boceprevir and telaprevir PK was assessed through comparison with historical data for each hepatitis C virus (HCV) drug's prescribing information alone. METHODS This was a single-centre, randomized, open-label, two-cohort, two-period, one-way study in healt...
Hepatitis C virus (HCV) antibody is present in most patients enrolled in methadone maintenance programs. Therefore, interactions between the HCV protease inhibitor telaprevir and methadone were investigated. The pharmacokinetics of R- and S-methadone were measured after administration of methadone alone and after 7 days of telaprevir (750 mg every 8 h [q8h]) coadministration in HCV-negative sub...
BACKGROUND Current therapy for chronic hepatitis C virus (HCV) infection is effective in less than 50% of patients infected with HCV genotype 1. Telaprevir, a protease inhibitor specific to the HCV nonstructural 3/4A serine protease, rapidly reduced HCV RNA levels in early studies. METHODS We randomly assigned patients infected with HCV genotype 1 to one of three telaprevir groups or to the c...
