Bristol-Myers Squibb Presents Phase II Hepatitis C Data

Bristol-Myers Squibb Company

announced Sunday new Phase II data demonstrating that the dual regimen of the investigational NS5A replication complex inhibitor daclatasvir (DCV) and the investigational NS3 protease inhibitor asunaprevir (ASV), without interferon or ribavirin, achieved high rates of sustained virologic response 12 weeks post-treatment (SVR12) in patients with genotype 1b (GT1b) hepatitis C virus (HCV) who were prior null responders to alfa interferon and ribavirin (alfa/RBV). In this study, the DCV/ASV Dual regimen achieved SVR12 in 78% (14/18) and 65% (13/20) of GT1b patients when asunaprevir was dosed twice daily (Group A1) or once daily (Group A2), respectively. These results were presented today at the American Association
