CHB participants:

* CHB infection (HBsAg-positive for \>/= 6 months)
* On NUC (ETV, TAF, or TDF) monotherapy for \>/= 12 months
* Liver biopsy, FibroScan, or equivalent test within the past 6 months demonstrating liver disease consistent with chronic HBV infection without evidence of bridging fibrosis or cirrhosis
