This multicenter study will evaluate the correlation of interleukin 28B (IL28B) genotypes with disease characteristics and demographics in treatment-naïve and treatment-experienced chronic hepatitis C patients, including patients with HIV co-infection. There will be a single study visit for testing.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Correlation of interleukin 28B (IL28B) genotypes rs12979860 (CC vs. TC vs. TT) and rs8099917 (TT vs. GT vs. GG) with liver fibrosis related to CHC [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Correlation of IL28B genotypes with liver inflammation related to CHC [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Correlation of IL28B genotypes with demographics in patients with CHC [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Distribution of IL28B genotypes according to CHC genotypes/countries [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Correlation between the IL28B genotypes rs12979860 and rs8099917 in patients with CHC [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Distribution of inosine triphosphatase (ITPA) genotypes in patients with CHC according to CHC genotype/countries [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Correlation between IL28B genotypes and previous treatment outcome in treatment-experienced CHC patients [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Correlation between ITPA genotypes and hemoglobin decline during prior treatment [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
