STUDY DESIGN: this study has 6 arms with the first 4 arms including in 2 different ways peg/RBV, and arms 5 & 6 (E & F) looking at IFN-free triple oral VX222+TLV+RBV for 12 weeks with option to add peg/RBV. See study design chart in attached report. We investigated whether IL28B rs12979860 could predict SVR or early treatment response (Week 2) in the ZENITH QUAD arms.
YOU will note arms E & F in this study (see study design in attached full report) are interferon-free, VX222 400mg bid + Telaprevir bid + Ribavirin, in 46 patients for 12 weeks, with an option of adding peg/rbv after 12 weeks of IFN-free. The results are from part of the study are not ready yet for presentation so are not in this poster but we expect it soon. Vertex has 2 nucleotides (acquired from Alios) that they are studying now in phase 1 with results expected soon, within a few months, whereupon based on these results from the phase 1 nucleotide studies new studies will quickly be designed including all of the Vertex orals which in total add up to a potential of 4 oral drugs that can be utilized in such studies (telaprevir, VX222, 2 nucleotides).
