Objectives
Primary Objective(s) & Hypothesis(es)
(1) Objective: To evaluate the efficacy of MK-5172 in combination with MK-8742 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.
Hypothesis: The proportion of subjects receiving MK-5172 in combination with MK8742 in the immediate treatment arm achieving SVR12 will be superior to 73%.
(2) Objective: To evaluate the safety and tolerability of MK-5172 in combination with MK8742.
3.2 Secondary Objective(s) & Hypothesis(es)
(1) Objective: To evaluate the efficacy of MK-5172 in combination with 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.
Other Objectives (e.g., Tertiary, Exploratory, etc.)
(1) Objective: To evaluate the efficacy of MK-5172 in combination with MK-8742 as assessed by the proportion of subjects in the immediate treatment arm achieving undetectable (TND) HCV RNA and HCV RNA < LLOQ at Week 2, 4, 12 and FollowUp Week 4 (SVR 4).
(2) Objective: To describe and compare patient-reported outcomes related to health-related quality of life, fatigue, and work productivity/activity impairment before, during, and after treatment with MK-5172 and MK-8742 versus placebo.
(3) Objective: To evaluate the emergence of viral resistance-associated variants (RAVs) to MK-5172 or MK-8742 when administered as part of a combination regimen.
(4) Objective: To evaluate the pharmacokinetics (PK) of MK-5172 and MK-8742.
(5) Objective: To explore the relationship between genetic variation and subject response to the treatment(s) administered.

Inclution Criteria
Subject Inclusion Criteria
In order to be eligible for participation in this trial, the subject must:
1. be ≥18 years of age on day of signing informed consent
2. HCV RNA (≥ 10,000 IU/mL in peripheral blood) at the time of screening
3. have documented chronic HCV GT1, GT4, GT5 or GT6 (with no evidence of nontypeable or mixed genotype) infection:
Positive for anti-HCV antibody, HCV RNA, or any of the above HCV genotypes at least 6 months before screening, or Positive for anti-HCV antibody or HCV RNA at the time of screening with a liver biopsy consistent with chronic HCV infection (or a liver biopsy performed before enrollment with evidence of CHC disease, such as the presence of fibrosis)
4. have liver disease staging assessment as follows:
Cirrhosis is defined as any one of the following [28, 29]:
A liver biopsy performed prior to Day 1 of this study showing cirrhosis (F4) Fibroscan performed within 12 calendar months of Day 1 of this study showing cirrhosis with result >12.5 kPa [29]* A FibroSure® (Fibrotest® ) performed during Screening with a score of >0.75 and an aspartate aminotransferase (AST): platelet ratio index (APRI) of >2. APRI formula:
AST÷lab upper limit of normal (ULN) for AST x 100÷ {platelet count÷100} (APRI
calculation to be provided by the central laboratory.)
Absence of cirrhosis is defined as any one of the following:
Liver biopsy performed within 24 months of Day 1 of this study showing absence of
cirrhosis
Fibroscan performed within 12 months of Day 1 of this study with a result of ≤12.5
kPa [29]*
A Fibrosure®
(Fibrotest®
) score of ≤0.48 and Aspartate Aminotransferase to Platelet
Ratio Index (APRI) of ≤1 during Screening
* Fibroscan cut-off of 12.5 kPa has a positive predictive value of 90% and a sensitivity of 95% for
≥F3. Based on box and whisker plot of interquartile distribution >12.5 kPa will exclude the majority
of subjects with metavir F3 fibrosis.
In the absence of a definitive diagnosis of presence or absence of cirrhosis by the above criteria, a liver biopsy is required. Liver biopsy results supersede the results obtained by Fibroscan® or Fibrosure®.
