| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objectives of this study are to evaluate the safety of 12 weeks of treatment with ABT-450/r/ABT-267 and ABT-333 with and without RBV, and to show the non-inferiority in SVR12 rates (the percentage of subjects achieving a 12-week sustained virologic response, SVR12, [HCV RNA < LLOQ 12 weeks following therapy]) of both arms to the historical SVR rate of telaprevir plus pegIFN and RBV. |
|
| E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are:
- To compare the percentage of subjects with a decrease in hemoglobin to below the lower limit of normal (LLN) by the end of treatment with ABT-450/r/ABT-267 and ABT-333 with RBV and without RBV;
- To show the superiority in SVR12 rates of 12 weeks of treatment with ABT-450/r/ABT-267 and ABT-333 with and without RBV to the historical SVR rate of telaprevir plus pegIFN and RBV therapy;
- To show the non-inferiority in SVR12 rates of 12 weeks of treatment with ABT-450/r/ABT-267, and ABT-333 without RBV (3 DAA/12) to 12 weeks of treatment with ABT-450/r/ABT-267 and ABT-333 with RBV (3 DAA/RBV/12);
- To summarize the percentage of subjects with virologic failure during treatment and the percentage of subjects with relapse post-treatment in each of the treatment groups. |

| E.5 End points |
| E.5.1 | Primary end point(s) |
The primary efficacy endpoints are:
(1) SVR12: non inferiority of Arm 2 to the historical rate for telaprevir plus pegIFN/RBV.
(2) SVR12: non inferiority of Arm 1 to the historical rate for telaprevir plus pegIFN/RBV
|
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| 12 weeks after last dose of study drugs |
|
| E.5.2 | Secondary end point(s) |
The secondary efficacy endpoints included in the fixed-sequence are:
(3) Comparison of the percentage of subjects with a decrease in hemoglobin to below the lower limit of normal (LLN) at the end of treatment with ABT-450/r/ABT-267 and ABT-333 with RBV versus without RBV.
(4) SVR12: Superiority of Arm 1 to the historical rate for telaprevir plus pegIFN/RBV
(5) SVR12: Superiority of Arm 2 to the historical rate for telaprevir plus pegIFN/RBV
(6) SVR12: Non-inferiority of Arm 2 to Arm 1.
Other secondary endpoints not included in the fixed sequence are:
● The percentage of subjects in each treatment group with virologic failure during treatment (defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during treatment or confirmed HCV RNA ≥ LLOQ at the end of treatment), and
● The percentage of subjects in each treatment group with post-treatment relapse (defined as confirmed HCV RNA ≥ LLOQ between end of treatment and 12 weeks after the last dose of study drugs among subjects completing treatment and with HCV RNA < LLOQ at the end of treatment).
