Core Tip

Core tip: This phase 3 study describes the first prospective comparison of an NS5A inhibitor and an NS3/4A protease inhibitor in peginterferon-based regimens. Combinations of peginterferon alfa-2a/ribavirin (pegIFN/RBV) with boceprevir or telaprevir were the standard-of-care for genotype (GT) 1-infected patients at the time of study design. In treatment-naive GT1b-infected patients, daclatasvir (NS5A inhibitor) plus pegIFN/RBV achieved a sustained virologic response at posttreatment week 12 (SVR12) of 85% and demonstrated noninferiority to telaprevir plus pegIFN/RBV showing 81% SVR12. Daclatasvir plus pegIFN/RBV was well-tolerated, with a superior safety profile for anemia compared with telaprevir plus pegIFN/RBV. These results support the ongoing investigation of daclatasvir in all-oral combinations in multiple patient populations.
