Eligibility
Key inclusion criteria

* Plasma or serum HBsAg concentration >100 IU/mL, but no greater than =3000 IU/mL.
* Plasma or serum HBV DNA concentration must be adequately suppressed, defined as plasma or serum HBV DNA <90 IU/mL.
* Alanine aminotransferase (ALT) =2 × upper limit of normal (ULN).
* Participants who are willing and able to cease their NA treatment in accordance with the protocol.
Minimum age
18 Years
Maximum age
No limit
Sex

Key exclusion criteria
* Clinically significant abnormalities, aside from chronic HBV infection in medical history (e.g., moderate severe liver disease other than chronic HBV, acute coronary syndrome within 6 months of screening, major surgery within 3 months of screening, significant/unstable cardiac disease, uncontrolled diabetes, bleeding diathesis or coagulopathy) or physical examination.

Co-infection with:

a) Current history of Hepatitis C infection or participants that have been cured for <12 months at the time of screening b) Human immunodeficiency virus (HIV), c) Hepatitis D virus.

* History of or suspected liver cirrhosis and/or evidence of cirrhosis.
* Diagnosed or suspected hepatocellular carcinoma.
* History of malignancy within the past 5 years except for specific cancers that are cured by surgical resection (e.g., skin cancer). Participants under evaluation for possible malignancy are not eligible.
* History of vasculitis or presence of symptoms and signs of potential vasculitis (e.g., vasculitic rash, skin ulceration, repeated blood detected in urine without identified cause) or history/presence of other diseases that may be associated with vasculitis condition (e.g., systemic lupus erythematosus, rheumatoid arthritis, relapsing polychondritis, mononeuritis multiplex).

* History of alcohol or drug abuse/dependence.
* Currently taking, or took within 3 months of screening, any immunosuppressing drugs (e.g., prednisone), other than a short course of therapy (=2 weeks) or topical/inhaled steroid use.
