ABT-450.r plus ABT 333 Phase II studies in Hepatitis C announced by Abbott Labs

Abbott Labs will present clinical trial results from two different interferon-free, Phase II studies for the treatment of Hepatitis C (HCV) at the International Liver Congress(TM) 2012 (ILC 2012), the annual meeting of the European Association for the Study of the Liver (EASL), April 18-22 in Barcelona, Spain. Abstracts for the meeting were published online today. In the study known as "Co-Pilot," different doses of ABT-450/r, plus ABT-333 and ribavirin administered for 12 weeks showed sustained virological response at 12 weeks post treatment (SVR12) in 95 percent and 93 percent of treatment-naive genotype 1 (GT1) patients. In these patients, response was independent of HCV subtype, host IL28B genotype or dose of ABT-450/r. In addition, SVR12 was achieved in 47 percent of patients who were previous non-responders to past HCV treatment.In a separate study, known as "Pilot," 91 percent of genotype 1 infected, treatment-naive patients taking ABT-450/r and ABT-072 combined with ribavirin administered for 12 weeks, achieved sustained viral response at 24 weeks (SVR24).Full results with longer-term follow-up data from both studies will be presented at the meeting.
