Brief Summary:
The TARGET-HBV study engages an observational research design to conduct a comprehensive review of outcomes for patients with CHB infection. The initial phase of the study that enrolled patients treated with tenofovir alafenamide (TAF) was successfully completed. The current protocol (Amendment 1) describes the second phase of the study that will engage research activities for patients being managed for CHB in usual clinical practice in the US and Canada. The study addresses important clinical questions regarding the management of CHB by collecting and analyzing data from patients at academic and community medical centers. TARGET-HBV creates a robust database of real-world data regarding the natural history, management, and health outcomes related to antiviral treatments used in clinical practice.

Biospecimen Retention:   Samples With DNA
Patients enrolled in TARGET-HBV may be invited to participate in the Biorepository Bank (BSB). Blood samples for biomarker and DNA assays will be collected on a voluntary basis and participation in this project will not affect participation in the main study. These samples will be shipped to a central repository for storage to use in future studies. Samples stored at the biorepository will be identified only with the participant's unique study ID number and the date the sample was obtained. The link between the participant's study ID number and their name will be available only at the site where the samples were obtained.
