    Background: BMS-790052 is a first-in-class, highly potent, once-daily HCV NS5A

    inhibitor. In Phase I studies in HCV-infected subjects, BMS-790052 was well-tolerated and

    exhibited potent antiviral activity.Methods: In this double-blind study, 48 subjects were randomized 1:1:1:1 to receive

    placebo, 3 mg, 10 mg or 60 mg of BMS-790052, once-daily in combination with

    peginterferon-alpha-2a and ribavirin (P/R) for 48 weeks in treatment-naive HCV genotype

    1-infected subjects. The primary endpoint was the proportion of subjects with extended

    rapid virologic response (eRVR) defined as HCV RNA < 10 IU/mL at both Weeks 4 and 12.

    Results: Subject baseline and demographic characteristics were well-balanced across

    treatment arms (n = 12/arm), with mean baseline HCV RNA 6.5 log10 IU/mL. The

    proportion of subjects achieving eRVR was 42%, 83% and 75% in the 3 mg, 10 mg and 60

    mg BMS-790052 + P/R arms, respectively, compared to 8% for P/R. Safety was

    comparable across treatment arms (see table). Adverse events were consistent with those

    commonly observed with P/R. Confirmed viral breakthrough was not observed in the 10mg and 60 mg BMS-790052 arms through Week 12.

    Conclusions: BMS-790052 is a potent once-daily NS5A inhibitor that yielded higher

    eRVR, RVR, and cEVR rates when combined with P/R than P/R alone. The addition of

    BMS-790052 to P/R was well-tolerated with an AE profile comparable to P/R. These results

    support further development of BMS-790052 in combination with P/R or other HCV

    antivirals.
