Inclusion criteria
Inclusion criteria: • Adult subjects, ages 18-65 infected with chronic HCV of any genotype who have previously been treated with RIBA and/or INF (or pegylated interferon) who either 1) did not achieve or maintain a sustained virologic response after RIBA and/or INF or 2) did not tolerate RIBA and/or INF treatment. • Alternatively, subjects may be eligible if they have contraindications to receiving INF and/or RIBA therapy • ALT = 1.5 x ULN but =65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: • decompensated liver disease • evidence of hepatocellular carcinoma (i.e., alpha-fetoprotein 50 ng/mL) • positive urine drug screen for opiates, cocaine or amphetamines • co-infection with hepatitis B virus (HBV) • human immunodeficiency virus (HIV); pancreatitis • recent significant infection or symptoms of infection (including mononucleosis or active herpes simplex virus) • autoimmune disorders • transplantation • history of malignancy • ongoing alcohol abuse (defined as intake of more than 28 units of alcohol per week

| Main Objective: • To investigate the safety and tolerability of multiple oral doses of GS-9450 in subjects with chronic hepatitis C (HCV). ;Secondary Objective: • To investigate the pharmacokinetics of multiple oral doses of GS 9450 and its metabolites in subjects with chronic HCV • To investigate the activity of multiple oral doses of GS 9450 in subjects with chronic HCV, as evidenced by: (1) change from baseline in alanine aminotransferase (ALT) levels (primary activity measure), (2) change in aspartate aminotransferase (AST) levels, and (3) change in noninvasive markers indicative of hepatic apoptosis, including cytokeratin 18 caspase-cleavage fragment [CK-18]) • To investigate the effects of GS 9450 on hepatitis C viral load ;Primary end point(s): • The primary safety endpoint will evaluate the tolerability of multiple oral doses of GS-9450. This endpoint will be assessed as treatment limiting adverse events or laboratory abnormalities that require premature discontinuation from the study. • The primary activity endpoint will be change from baseline in ALT levels at Day 14. • The primary pharmacokinetic endpoints of this study are to characterize the plasma PK parameters of GS-9450 and metabolites following multiple doses of GS-9450 using standard non compartmental methods. | — |
