Hepatitis C, Chronic
About this trial
This is an interventional trial for Hepatitis C, Chronic focused on measuring Hepatitis C, HCV, HCV RNA, Polymerase inhibitor, Treatment naïve, GS-6620
Eligibility Criteria
Inclusion Criteria:
- Adult subjects (18-60 years of age or up to 64 years of age with approval)
- Documented chronic HCV infection to be of at least 6 months duration and plasma HCV RNA ≥ 5 log10 IU/mL at screening.
- HCV treatment naïve
- Estimated creatinine clearance ≥ 80 mL/min,
- QTcF interval ≤ 450 msec, QRS duration < 100 msec, PR interval < 220 msec,
- Body mass index (BMI) of 19.0 to 34.0 kg/m2, inclusive.
- Eligible subjects must also be HCV treatment-naïve.
Exclusion Criteria:
- Subjects with prior documentation of cirrhosis, excessive current alcohol intake, any evidence of hepatocellular carcinoma (i.e., α-fetoprotein > 50 ng/mL or by any other standard of care measure)
- Urine drug screen positive for illicit/illegal drugs
- ALT and AST levels > 5 times the upper limit of the normal range (ULN)
- Direct bilirubin > ULN, clinical or other laboratory evidence of hepatic decompensation (i.e., platelets < 100,000/mm3, prothrombin time ≥ 1.5 × ULN and albumin < 3.5 g/dL) are not eligible for study participation.
- Subjects with an absolute neutrophil count (ANC) < 1,000 cells/mm3 (< 750 cells/mm3 for black or African-American subjects), hemoglobin (Hb) < 11 g/dL,
- Coinfected with hepatitis B virus (HBV), human immunodeficiency virus (HIV), or another HCV genotype (other than type 1 for Cohorts 1-5 and type 2 or 3 for Cohort 6) are not eligible for study participation.
- Evidence of hepatocellular carcinoma
- Any sign of decompensated liver disease, including prothrombin time ≥ 1.5 X ULN, platelets < 100,000/mm3 or albumin < 3.5 g/dL at screening OR current or prior history of clinical hepatic decompensation (e.g., ascites, jaundice, encephalopathy or variceal hemorrhage)
- History of clinically-significant illness or any other major medical disorder that may interfere with subject treatment, assessment or compliance with the protocol
- History of a primary gastrointestinal disorder that could interfere with the absorption of the study drug or that could interfere with normal gastrointestinal anatomy or motility
