This is a Phase 2, open-label,randomized, multiple dose, varied administration regimen study with 2 parts (Parts A and B) in Subjects Infected with Chronic Hepatitis B Virus
This non-interventional clinical study will be conducted to prospectively collect serial plasma samples from subjects with chronic HBV infection who are initiating antiviral therapy. These samples will be used to estimate clinical utility endpoints for the Aptima HBV Quant assay, which is used as an aid in the management of HBV-infected patients undergoing HBV antiviral therapy.
The purpose of this study is to evaluate the safety and efficacy of tenofovir alafenamide (TAF) compared to that of tenofovir disoproxil fumarate (TDF) in treatment naive and experienced adult subjects with chronic hepatitis B virus (HBV) infection, as determined by the achievement of HBV DNA < 29 IU/mL at Week 48.
