This cross-sectional multicenter study will evaluate the IL28B polymorphism in patients with HBeAg-negative chronic hepatitis B treated with Pegasys (peginterferon alfa-2a) in the predecessor ML18253 study. The study consists of a single visit where eligible patients will undergo a blood test for IL28B genotyping, with a phone follow-up 7 days after the visit.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Percentage of patients with sustained virological response (SVR) observed in ML18253 according to IL28B genotypes. SVR is defined as HBV DNA </= 2000 UI/ml at the end of the treatment-free follow-up [ Time Frame: approximately 24 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of patients with HBsAg clearance (defined as HBsAg <0.05 UI/ml) according to IL28B genotypes at end of treatment/end of follow-up in ML18253 [ Time Frame: approximately 24 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with HBsAg </= 10 IU/ml at end of treatment/end of follow-up according to IL28B genotypes in ML18253 [ Time Frame: approximately 24 weeks ] [ Designated as safety issue: No ]
  • HBsAg kinetic according to IL28B genotypes during treatment/follow-up in ML18253 [ Time Frame: approximately 24 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with virologic response at the end of treatment (HBV DNA </= 200 UI/ml) observed in ML18253 according to IL28B genotype. [ Time Frame: approximately 24 months ] [ Designated as safety issue: No ]
