Beschreibung
Inclusion Criteria:
- Male or female participants, aged 18-65 years old (inclusive)
- Body Mass Index between 19 to 35 kg/m2 (inclusive)
- Body weight > or = 45 kg.
- Documented HBV infection for ≥6 months prior to randomization.
- For Parts A and B, on stable approved NA monotherapy for at least 6 months prior to randomization.
- For Part C and D only, not on any NA monotherapy for at least 6 months prior to randomization.
- Screening electrocardiogram (ECG) without clinically significant abnormalities
- Females of childbearing potential must not be breastfeeding, must have a negative serum pregnancy test at Screening, and a negative urine/serum pregnancy test before dosing (unless permanently sterile or >2 years postmenopausal).
- Males and females of childbearing potential must agree to use protocol specified reliable contraception throughout the study.
- Screening HBV DNA, HBsAg and ALT must meet prespecified requirements.
Exclusion Criteria:
- Significant medical conditions other than chronic HBV (e.g. recent heart issues, unstable cardiac disease, uncontrolled diabetes, bleeding disorders, prior organ transplant).
- Other clinically significant liver diseases (e.g. hepatitis from other causes, autoimmune or alcoholic liver disease, prior liver failure).
- History of suspected or confirmed cirrhosis (based on FibroScan® or biopsy).
- Current, past, or suspected liver cancer, or elevated alpha-fetoprotein (AFP) ≥ 20 ng/mL.
- HBV-related extrahepatic diseases (e.g. kidney or vascular conditions).
- Severe infection (other than chronic HBV infection) within 1 month before randomization requiring intravenous treatment.
- Active infections: human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis D virus (HDV) or syphilis (exceptions if RNA negative).
- Abnormal lab results (e.g. low albumin, reduced kidney function, abnormal INR, low platelets, high bilirubin, abnormal blood counts, significant proteinuria).
- History or signs of vasculitis or related autoimmune diseases.
- Malignancy within 5 years (except non-melanoma skin cancer).
- Allergy to study drug components.
- Recent major surgery/trauma (within 3 months) or planned surgery during study.
- Alcohol or substance abuse affecting compliance.
- Pregnancy, breastfeeding, or unwillingness to follow reproductive restrictions.
- Participation in another clinical trial or recent investigational product use.
- Prior treatment with any antisense oligonucleotide or small interfering RNA therapies.
- Recent or ongoing use of immunosuppressive/biologic therapies, certain vaccines, bulevirtide, or unapproved herbal remedies.
- Need for long-term anticoagulants/antiplatelet drugs (unless safely stopped).
- Any other condition making the participant unsuitable (per investigator).
