Hepatitis B, Chronic Clinical Trial
Official title:
An Exploratory Evaluation of Interleukin 28B (IL28B) Genotype, Single Nucleotide Polymorphisms (SNP) of rs12356193, Protein and RNA Biomarkers in Serum Samples (Stored, Already Obtained From Completed Studies) From Subjects With HBe-antigen Positive or Negative Chronic Hepatitis B, Who Have Completed Therapy for Hepatitis B With Pegasys ± Lamivudine.
This retrospective study will evaluate the association of biomarkers and the treatment response of patients with chronic hepatitis B, who have completed therapy with Pegasys (peginterferon alfa-2a) ± lamivudine. For the analysis stored serum samples obtained from patients will be used; no actual patients are involved.
