Description
Inclusion Criteria:
- Signed the informed consent form;
- Male or female aged 18 to 70 years;
- Positive HBsAg at screening;
- History of chronic HDV infection for at least 6 months prior to randomization. For subjects also recommended for anti-HBV therapy, previous first line NrtIs treatment (ETV, TDF, TAF) within at least 12 weeks prior to the planned start of study treatment or subject's willingness to take first line NrtIs treatment for at least 12 weeks prior to the planned start of study treatment is required;
- Positive HDV antibody at screening;
- HDV RNA ≥100 IU/mL at screening;
- 1×ULN<Alanine aminotransferase (ALT) <10×ULN at screening;
Exclusion Criteria:
- Subjects with known hypersensitivity to HH-003 and its components, history of severe allergic reaction to other therapeutic antibodies or severe allergic diseases;
- Subjects with contraindications for TAF;
- History of interferon therapy within 3 months before randomization;
Any of the following lab test results at screening:
- Total bilirubin >2×ULN (except for subjects with Gilbert syndrome);
- Direct bilirubin > 1.5×ULN ;
- Platelets<80,000/mm3 (80×109/L);
- Serum Albumin <35 g/L;
- Prothrombin time international normalized ratio (INR) >1.3;
- Hemoglobin <100 g/L;
- Absolute neutrophils<1,500/mm3 (1.5×109/L);
- Estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73m2 (according to the calculation equation of CKD-MDRD);
- Concomitant decompensated cirrhosis (cirrhosis with complications of portal hypertension and/or decreased hepatic function). The diagnosis of cirrhosis is based on, but not limited to: liver imaging assessment within 6 months prior to randomization (including screening period) (e.g.: liver ultrasound) or cirrhosis indicated by histopathology of liver biopsy, or liver stiffness measurement LSM≥17 kPa at screening, refer to more serious reported findings;
- Hepatic insufficiency within 3 months prior to randomization (including but not limited to: ascites, hepatic encephalopathy, upper gastrointestinal hemorrhage);
- Previous or current hepatocellular carcinoma (HCC) or suspicion for HCC suggested by liver histopathology or liver imaging; or serum alpha-fetoprotein (AFP) ≥ 50 ng/mL at screening;
- Subjects with history of alcoholic liver disease, nonalcoholic steatohepatitis, autoimmune liver disease or other hereditary liver diseases, drug-induced liver disease or other clinically significant chronic liver diseases not caused by HDV/HBV;
- History of other malignancies other than HCC, unless the subject's malignancy has been in complete remission within 3 years prior to screening and does not require chemotherapy and additional medical or surgical intervention; invasive medical devices within 1 month before randomization.
