Setrobuvir (ANA598), Anadys’ most advanced drug candidate, is currently being evaluated by Anadys in a Phase II study in combination with Roche’s pegylated interferon (Pegasys) and ribavirin (Copegus).

Jean-Jacques Garaud, Global Head of Roche Pharma Research and Early Development, said: "This acquisition augments our already strong HCV portfolio. Our aim is to offer physicians and hepatitis patients a powerful combination of therapies that bring us closer to a cure, even without the use of interferon."

Anadys is also developing ANA773, an oral, small-molecule inducer of innate immunity in Phase I trials that may prove useful for treating HCV and cancer.
