1. be =18 years of age on day of signing informed consent.
2. have a body weight =50 kg (111 lbs) and = 125 kg (275 lbs).
3. have chronic, compensated HCV GT 1a or GT 1b infection:
• Positive serology for HCV with HCV RNA levels = 10,000 IU/mL in peripheral blood at screening, and
• Absence (no medical history or physical findings) of ascites, bleeding esophageal varices, hepatic encephalopathy, or other signs or symptoms of advanced liver disease, or cirrhosis.
4. have had a liver biopsy without evidence of advanced fibrosis, cirrhosis and/or hepatocellular carcinoma. A liver biopsy done prior to screening is acceptable if it is performed:
• Within 2 years of screening and the result was METAVIR (or equivalent) Stage 0 (F0) to 2 (F2).
If the prior liver biopsy was obtained outside the acceptable windows, a repeat biopsy may be performed, and the results must show no evidence of advanced fibrosis, cirrhosis and/or hepatocellular carcinoma in order for the subject to be randomized in the study.
For countries where liver biopsy is not performed prior to treatment and where noninvasive tests (for e.g. FibroScan and/or FibroTest) are used for staging of liver disease, these results may be used to assess eligibility. Subjects with a documented FibroScan score of =9.5 kPa, or FibroTest score of =0.58, are allowed to be enrolled in the study. These non-invasive tests done prior to screening are acceptable if they were performed within 1 year of screening and meet the indicated cut-offs. If the prior non-invasive tests were not performed within 1 year of screening, results from one of these non-invasive tests are required before study drug dosing. If a subject has both liver biopsy and one of these non-invasive tests, whichever test demonstrates the presence of advanced fibrosis or cirrhosis would be used to determine eligibility. In other words, if the liver biopsy shows advanced fibrosis or cirrhosis, the subject is excluded, regardless of results of the non-invasive assay. If the liver biopsy does not show advanced fibrosis or cirrhosis, but the non-invasive assay does, then the subject is excluded as well.
5. agree to use two acceptable methods of birth control from at least 2 weeks prior to Day 1 and continue until at least 6 months after last dose of study drug, or longer if dictated by local regulations (for female subject who is of childbearing potential or male subject with female sexual partner who is of childbearing potential).
If acceptable by local regulatory agencies, methods of birth control allowed in the study are: intrauterine device (IUD), diaphragm with spermicide, contraceptive sponge, female condom, male condom with spermicide, vasectomy, and true abstinence: Abstinence is in line with the preferred and usual lifestyle of the subject. [Periodic abstinence (e.g., abstinence only on certain calendar days, abstinence only during ovulation period, use of symptothermal method, use of post-ovulation methods) and withdrawl are not acceptable methods of contraception]. Hormonal contraceptives (e.g., birth control pills, transdermal patch, or injectables) are unacceptable methods of birth control for use in this study because it is not known whether these methods are affected by co-administration of MK-5172 and/or MK-8742.
For the purposes of this protocol, a woman of non-childbearing potential is defined as one who has either 1) reached natural menopause (defined as 6 months of spontaneous amenorrhea with seru
1) has a non-GT 1 HCV infection, including a mixed GT infection (with a non-GT 1) or a non-typeable genotype.
2) is NOT treatment naïve, i.e. subject has had previous treatment with any interferon, ribavirin, approved or experimental direct acting antiviral(s), or other investigational therapies for HCV.
3) As determined by documented records, subject is HIV positive or known to be coinfected with hepatitis B virus (HBsAg positive).
4) has evidence of hepatocellular carcinoma (HCC) or is under evaluation for HCC.
5) has pre-existing psychiatric condition(s)
6) has any known medical condition that could interfere with the subject's participation in and completion of the trial
7) has evidence of active or suspected malignancy, or a history of malignancy, within the last 5 years
8) (female) is pregnant, lactating, expecting to conceive or donate eggs, or is of childbearing potential and unwilling to commit to two methods of birth control throughout treatment and after the completion of all treatment
9) is a male whose female partner(s) are pregnant
10) has exclusionary laboratory values as listed in the protocol
i) Hemoglobin <12 g/dL for females and <13 g/dL for males.
ii) Neutrophils <1.5 x 10^3/µL (<1.2 x 10^3/µL for Blacks).
iii) Platelets <150 x 10^3/µL
iv) Direct bilirubin >1.5 x ULN (upper limit of normal) of the laboratory reference range
v) PT/PTT values > 10% above laboratory reference range
vi) Anti-nuclear antibodies (ANA) > 1:320
vii) ALT > 350IU/L
viii) AST > 350 IU/L
