Abbott and Enanta Pharmaceuticals announced data from "Co-Pilot," an interferon-free, Phase 2 study of Abbott's direct-acting antiviral medicines for the treatment of hepatitis C (HCV) that found that more than 90 percent of patients new to HCV treatment achieved sustained viral response through 12 weeks (SVR12). Results were released today at a press conference at the International Liver Congress 2012 (ILC 2012), the annual meeting of the European Association for the Study of the Liver (EASL), in Barcelona, Spain, and will also be presented in an oral platform presentation at the latebreaking trials session on Saturday, April 21.
