SECONDARY outcome

Timeframe: 12 weeks

Population: All participants who received at least one dose of study medication

Mean change in Fibrosis-4 (FIB-4) score from Baseline to Week 1, Week 2, Week 4, Week 8, and Week 12. FIB-4 score is calculated as (age in years \* Aspartate aminotransferase (AST) in U/L)/(platelet count in 10\^9 U/L \* square root of alanine aminotransferase (ALT) in U/L). FIB-4 scores under 1.45 have a negative predictive value of 90% for advanced fibrosis (better outcome) and FIB-4 scores \>3.25 have a positive predictive value of 65% for advanced fibrosis (worse outcome). See Sterling RK, Lissen E, Clumeck N, et. al. Development of a simple noninvasive index to predict significant fibrosis patients with HIV/HCV co-infection. Hepatology 2006;43:1317-1325.
