NOTE A: For purposes of documenting hepatitis B status, an HBsAg or HBV DNA obtained in the 6 months prior to and up to the date of the screening visit is acceptable EXCEPT for subjects with a positive HBcAb at screening (see Note B). A negative HBeAg during the same period in the absence of an HBsAg or HBV DNA is not sufficient evidence of HBV-negative status. If a clinically obtained test is not available at screening, an HBsAg will be drawn together with other evaluations at this visit.
