approached about participating. if they are not eligible, unwilling to participate or have completed their
participation in the treatment study, they will be followed longitudinally to observe clinical outcomes
and changes in their virologic and immunologic status.
it is estimated that approximately 500 patients with HBV infection will be enrolled in the Cohort Study
