Summary
Treatment compliance is a key success factor in obtaining the full benefit of Pegetron (peginterferon alfa-2b [PegIFN-2b] plus ribavirin combination) therapy for patients. Treatment-naïve patients with chronic hepatitis C (CHC) in Canada to whom Pegetron Redipen was prescribed will receive Pegetron Redipen therapy in accordance with approved labeling. The study will assess the effect of the newly approved Pegetron Redipen on treatment compliance and its effect on sustained virologic response rates. Sustained virologic response is defined as negative hepatitis C virus ribonucleic acid (HCV-RNA) six months post-treatment.
