The overall goal of this trial is to evaluate the efficacy of FG-3019 for reversing liver fibrosis in subjects with chronic hepatitis B infection who are beginning antiviral therapy with entecavir. This Phase 2 randomized, double-blind, placebo controlled study will enroll subjects with chronic active hepatitis B infection and liver fibrosis (Ishak score ≥2) who are eligible for antiviral therapy.
