Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: •To evaluate the efficacy of MK-5172A as assessed by the proportion of subjects in the immediate treatment arm achieving SVR12 (Sustained Virologic Response 12 weeks after the end of all study therapy), defined as HCV RNA < LLOQ (either TD[u] or TND) 12 weeks after the end of all study therapy •To evaluate the safety and tolerability of MK-5172A in the immediate treatment group relative to the placebo treatment of the deferred treatment group. ;Secondary Objective: •To evaluate the efficacy of MK-5172/MK-8742 as assessed by the proportion of subjects in the immediate treatment arm achieving SVR24 (Sustained Virologic Response 24 weeks after the end of all study therapy), defined as HCV RNA < LLOQ (either TD(u) or TND) 24 weeks after the end of all study therapy.;Primary end point(s): •The primary efficacy endpoint will be the SVR12 rate of the subjects in the immediate treatment arm. •The primary PK endpoints for MK-5172 and MK-8742 are C2hr and Ctrough. Additional PK parameters such as AUC0-24 may be calculated using population pharmacokinetic modeling approaches. ;Timepoint(s) of evaluation of this end point: SVR12 (FU Week 12) | — |
