  Purpose

This observational study will assess predictors of early on-treatment and sustai ned virological response in treatment-naïve patients with chronic hepatitis C in itiated on treatment with Pegasys (peginterferon alfa-2a) and ribavirin. Data wi ll be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <5000.


Condition Intervention
Hepatitis C, Chronic
Drug: peginterferon alfa-2a [Pegasys]

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Prospective Observational Study on Predictors of Early On-treatment Response and Sustained Virological Response in a Cohort of Treatment naïve HCV-infected Patients Treated With Pegylated Interferons.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Predictive values of virological response 4 and 12 weeks after treatment initiation on sustained virological response (SVR) by HCV genotype [ Time Frame: weeks 4 and 12, and 24 weeks after end of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Identification and confirmation of host-, virus- and treatment-related factors influencing viral response, SVR and relapse [ Time Frame: throughout treatment and 12 and 24 weeks after end of treatment ] [ Designated as safety issue: No ]
  • Correlation between overall treatment duration/treatment duration after HCV RNA becomes negative and SVR by genotype [ Time Frame: assessed 12 and 24 weeks after end of treatment ] [ Designated as safety issue: No ]
  • Correlation of cumulative ribavirin and peginterferon dose with SVR by genotype [ Time Frame: assessed 12 and 24 weeks after end of treatment ] [ Designated as safety issue: No ]
