Practice guidelines for the treatment of hepatitis C: recommendations from an AISF/SIMIT/SIMAST Expert Opinion Meeting.

2010

It is increasingly clear that a tailored therapeutic approach to patients with hepatitis C virus infection is needed. Success rates in difficult to treat and low-responsive hepatitis C virus patients are not completely satisfactory, and there is the need to optimise treatment duration and intensity in patients with the highest likelihood of response. In addition, the management of special patient categories originally excluded from phase III registration trials needs to be critically re-evaluated. This article reports the recommendations for the treatment of hepatitis C virus infection on an individual basis, drafted by experts of three scientific societies.

Effect of peginterferon alfa-2a on liver histology in chronic hepatitis C: a meta-analysis of individual patient data

2004

Multicenter randomized trials have shown that once-weekly pegylated interferon (peginterferon) alfa-2a is more efficacious than conventional interferon alfa-2a (IFN) in patients with chronic hepatitis C. We performed a meta-analysis of 1,013 previously untreated patients (from 3 randomized trials) with pretreatment and post-treatment liver biopsies to assess the differences between peginterferon alfa-2a and IFN in terms of their effects on liver histology. Reported values were standardized mean differences (SMD) between patients receiving peginterferon alfa-2a and those receiving IFN (post-treatment value minus baseline value for each group). We used a random-effects model to quantify the a…

Real-world outcomes in patients with chronic hepatitis C: primary results of the PROBE study.

2014

BACKGROUND This large prospective multicentre cohort study aimed to improve knowledge of therapy for chronic hepatitis C (CHC) in real clinical practice. METHODS A diverse population of adults with CHC including patients with comorbid conditions, laboratory abnormalities and demographic features [comorbidities or special populations (CSP)] who were under-represented or excluded from peginterferon registration studies was treated with peginterferon α-2a (40 kDa) or α-2b (12 kDa) plus ribavirin at the investigator's discretion. RESULTS During the study, 5399 treatment-naive patients [2527 (46.8%) with CSP] received peginterferon α-2a (n=3513, 65.1%) or peginterferon α-2b (n=1886, 34.9%). The …

Add-on peginterferon alfa-2a to nucleos(t)ide analogue therapy for Caucasian patients with hepatitis B ‘e’ antigen-negative chronic hepatitis B genot…

2019

Nucleos(t)ide analogues (NAs) and peginterferon have complementary effects in chronic hepatitis B, but it is unclear whether combination therapy improves responses in genotype D-infected patients. We conducted an open-label study of peginterferon alfa-2a 180 μg/week added to ongoing NA therapy in hepatitis B e antigen (HBeAg)-negative, genotype D-infected patients with HBV DNA <20 IU/mL. The primary endpoint was proportion of patients with ≥50% decline in serum HBsAg by the end of the 48-week add-on phase. Seventy patients received treatment, 11 were withdrawn at week 24 for no decrease in HBsAg, and 14 withdrew for other reasons. Response rate (per-protocol population) was 67.4% (29/43) at…

Cost effectiveness of boceprevir or telaprevir for previously treated patients with genotype 1 chronic hepatitis C.

2013

Background & Aims Randomised controlled trials (RCTs) show that triple therapy (TT) with peginterferon alfa, ribavirin, and boceprevir (BOC) or telaprevir (TVR) is more effective than peginterferon-ribavirin dual therapy (DT) in the treatment of genotype 1 (G1) chronic hepatitis C (CHC) patients with previous relapse (RR), partial response (PAR), and null-response (NR). We assess the cost-effectiveness of TT compared to no therapy in the treatment of patients previously treated with G1 CHC. Methods The available published literature provided the data source. The target population was made up of previously treated Caucasian patients with G1 CHC and these were evaluated over a lifetime horizo…

Anemia during treatment with peginterferon Alfa-2b/ribavirin and boceprevir: Analysis from the serine protease inhibitor therapy 2 (SPRINT-2) trial

2013

International audience; Boceprevir (BOC) added to peginterferon alfa-2b (PegIFN) and ribavirin (RBV) significantly increases sustained virologic response (SVR) rates over PegIFN/RBV alone in previously untreated adults with chronic hepatitis C genotype 1. We evaluate the relationship of incident anemia with triple therapy. A total of 1,097 patients received a 4-week lead-in of PegIFN/RBV followed by: (1) placebo plus PegIFN/RBV for 44 weeks (PR48); (2) BOC plus PegIFN/RBV using response-guided therapy (BOC/RGT); and (3) BOC plus PegIFN/RBV for 44 weeks (BOC/PR48). The management of anemia (hemoglobin [Hb]<10 g/dL) included RBV dose reduction and/or erythropoietin (EPO) use. A total of 1,080…

High sustained virologic response rates in children with chronic hepatitis C receiving peginterferon alfa-2b plus ribavirin

2010

Pegylated interferon (PEG-IFN) alfa-2b plus ribavirin (RBV) is the standard of care for adults with chronic hepatitis C but was not approved for the treatment of children at the time of this study. The aim of this study was to evaluate the efficacy and safety of PEG-IFN alfa-2b plus RBV in children.Children and adolescents ages 3-17 years were treated with PEG-IFN alfa-2b (60microg/m(2)/week) plus RBV (15mg/kg/day). The duration of therapy was 24 weeks for genotype (G) 2 and G3 patients with low viral load (600,000IU/ml) and 48 weeks for G1, G4, and G3 with high viral load (or=600,000IU/ml). The primary end point was sustained virologic response (SVR), defined as undetectable hepatitis C vi…

Which patients with genotype 1 chronic hepatitis C can benefit from prolonged treatment with the 'accordion' regimen?

2007

The on-treatment virological response to pegylated interferon plus ribavirin therapy is a useful tool in the management of patients with chronic hepatitis C. The time at which hepatitis C virus RNA becomes undetectable by a sensitive PCR assay has a huge impact on the probability of achieving a sustained virological response, particularly in genotype 1 patients, and may be useful in selecting patients for prolonged therapy. Indiscriminate extension of treatment in patients with hepatitis C virus genotype 1 is not beneficial. However, there is a subgroup of patients – the so-called ‘slow responders’ – who benefit from extending treatment from 48 to 72 weeks and can be readily identified afte…

Peginterferon alfa-2b and Ribavirin: Effective in Patients With Hepatitis C Who Failed Interferon alfa/Ribavirin Therapy

2009

Treatment with peginterferon alfa and ribavirin produces a sustained virologic response (SVR) in approximately 60% of hepatitis C virus (HCV)-infected patients. Alternate options are needed for patients who relapse or do not respond to therapy.This prospective, international, multicenter, open-label study evaluated efficacy and safety of peginterferon alfa-2b (1.5 microg/kg/wk) plus weight-based ribavirin (800-1400 mg/day) in 2333 chronic HCV-infected patients with significant fibrosis/cirrhosis whose previous interferon alfa/ribavirin therapy failed. Patients with undetectable HCV-RNA at treatment week (TW) 12 received 48 weeks of therapy; patients with detectable HCV-RNA at TW12 could ent…

An a priori prediction model of response to peginterferon plus ribavirin dual therapy in naïve patients with genotype 1 chronic hepatitis C.

2014

none 29 no Background: Aim was to select naïve patients with genotype 1 chronic hepatitis C having a high probability of response to Peg-interferon. +. ribavirin therapy. Methods: In 1073 patients (derivation cohort), predictors of rapid and sustained virological response were identified by logistic analysis; regression coefficients were used to generate prediction models for sustained virological response. Probabilities at baseline and treatment week 4 were utilized to develop a decision rule to select patients with high likelihood of response. The model was then validated in 423 patients (validation cohort). Results: In the derivation cohort, 257 achieved rapid virological response and 8…
