• Have documented chronic (at least 6 months) HCV GT1 infection (with no evidence of non typable or mixed genotypes) :
- Positive for anti-HCV antibody, HCV RNA, or an HCV genotype
- HCV RNA (= 10,000 IU/mL in peripheral blood)

Prior Treatment Relapse: Subjects relapsed after completing a prior course of HCV therapy that included IFN or PEG-IFN + Ribavirin but that did not include any direct acting antivirals.
• Have Chronic Kidney Disease defined as:
Subjects with GFR =29 who are non-dialysis dependent (NDD) or have been on hemodialysis (HD) for at least 3 months (including subjects awaiting kidney transplant and subjects with failed kidney transplants no longer on immunosuppressant therapy).
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 220

F.1.3.1 Number of subjects for this age range

• Evidence of decompensated liver disease manifested by the presence of or history of ascites, gastric or variceal bleeding, hepatic encephalopathy or other signs or symptoms of advanced liver disease. If hepatic cirrhosis is determined by liver biopsy (Stage 4 Metavir or Stage 5, 6 Ishak) participants must be excluded.
• Is on peritoneal dialysis for management of Kidney disease
• In the opinion of the investigator the subject has a high likelihood of receiving a renal transplant during the study treatment period (up to 24 weeks from Day 1).
• Is coinfected with hepatitis B virus (e.g. HBsAg positive) or HIV.
• Has a history of malignancy =5 years prior to signing informed consent except for adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer; or has evidence of hepatocellular carcinoma (HCC) or is under evaluation for other active or suspected malignancy.
• Is currently participating or has participated in a study with an investigational compound within 30 days of signing informed consent and is not willing to refrain from participating in another such study during the course of this study.
• Has a clinical diagnosis of substance abuse of the following specified drugs within specified timeframes:
- alcohol, intravenous drugs, inhalational (not including marijuana), psychotropics, narcotics, cocaine use, prescription or over-the-counter drugs: within 1 year of the screening visit or, if shorter is judged by the investigator to be capable of complying with study procedures, OR

- history of marijuana use is deemed excessive by a physician investigator or is interfering with the subject's daily function. If subject's marijuana use is not deemed excessive and does not interfere with daily function, subject must be instructed to discontinue any current use of recreational marijuana prior to entry into trial and throughout the trial period.
