Eligibility Criteria
Inclusion
- Subjects voluntarily sign the informed consent form.
- Subjects (including partners) are willing to have no plans for pregnancy from the time of screening to 3 months after the last administration of the study drug and ensure appropriate contraception measures are taken.
- Male or female subjects (including boundary values) between 18-65 years of age, regardless of gender.
- Body mass index (BMI) between 18.0-32.0 kg/m2 (including critical values), where BMI = body weight (kg) / height2 (m2).
- Evidence (including but not limited to outpatient/inpatient medical records/laboratory reports, etc.) to prove a history of positive hepatitis B surface antigen (HBsAg) or positive HBV DNA for at least 6 months at the time of screening, or negative HBcAb IgM and positive HBsAg at the time of screening, or histological examination of liver tissue showing chronic hepatitis B infection.
- HBeAg-positive patients with HBV DNA ≥ 2.0×104 IU/mL and HBeAg-negative patients with HBV DNA ≥ 2.0×103 IU/mL at the time of screening.
- Subjects with ALT between 1.2×ULN and 10×ULN within 7 days of screening, or subjects over 30 years of age with ALT less than 1.2×ULN; total bilirubin (TBIL) ≤ 2×ULN;
- Creatinine clearance rate ≥ 70 mL/min \[calculation formula: Ccr: (140-age)×weight (kg) / (0.818×Scr) (μmol/L), female×0.85\];
- Subjects who have not used anti-HBV nucleotide/nucleoside therapy, interferon therapy, or immunomodulators within the previous 6 months prior to screening;
- Subjects who fully understand the trial process, possible adverse reactions, and can complete the trial according to the protocol plan.
Exclusion
- Subjects with a history of allergies to HTS and TAF, or any other similar drugs, metabolites, or excipients;
- Subjects who participated in other drug clinical trials within one month prior to the study;
- Subjects with positive results for hepatitis C antibody, hepatitis C core antigen, HIV antibody, or syphilis antibody screen (if syphilis antibody positive, additional rapid plasma reagin test (RPR) is required, and the investigator should use the results to determine if there is a positive reaction);
- Subjects with any known disorders in glutathione metabolism (e.g., glutathione deficiency anemia, glutathioneemia), or subjects who require high doses of acetaminophen/Tylenol® (\>1 g/day);
- Subjects with a QTcF interval \>470 ms (men) or \>480 ms (women) on electrocardiogram at the time of screening (corrected using Fridericia's formula), or any other electrocardiogram abnormalities deemed to be clinically significant by the investigator;
- Subjects with a history of persistent substance abuse in the past or recent times;
- People who smoke and drink excessively (14 units of alcohol per week: 1 unit = 285 mL of beer, or 25 mL of hard liquor, or 1 glass of wine; smoking ≥ 5 cigarettes per day);
- People with decompensated liver disease (Child-Pugh score of B or C), including but not limited to: hepatic encephalopathy, hepatorenal syndrome, variceal bleeding, ascites, or a history of HCC;
- People with an alpha-fetoprotein (AFP) level \> 50 ng/mL at the time of screening, or with imaging suggesting the possibility of malignant liver lesions;
- People with a history of malignancy within the past 5 years \[exceptions: surgically resected and completely cured specific cancers (such as skin basal cell carcinoma or squamous cell carcinoma) or cervical intraepithelial neoplasia\];
- People with a history of organ transplantation or bone marrow transplantation;
- People who require long-term use of immunosuppressants or drugs with a high risk of liver or kidney toxicity (such as dapsone, erythromycin, fluconazole, ketoconazole, rifampicin, etc.);
- Pregnant or breastfeeding women or with positive serum pregnancy results;
- People with other significant liver diseases in addition to hepatitis B, including but not limited to chronic alcoholic hepatitis, drug-induced hepatitis, autoimmune liver disease, etc.
- Other serious diseases of important organs include but are not limited to definite medical history of nervous system, cardiovascular system, urinary system, digestive system, respiratory system, metabolism and skeletal muscle system (such as poorly controlled diabetes (type 1 diabetes or uncontrolled type 2 diabetes (HbA1c≥9.0%)), hypertension that is not well-controlled after medication (systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg), etc.), which the investigator believes makes the subject unsuitable for participation in this study;
- A history of swallowing difficulties or any gastrointestinal diseases that affect drug absorption;
- Donating blood or losing blood \>500 mL within 2 months prior to screening, or donating plasma within 14 days prior to screening;
- Any significant clinical and laboratory abnormalities (neutrophil count \<1.2×109/L during screening; platelet count \<80×109/L during screening; hemoglobin \<90g/L during screening; international normalized ratio (INR) \>1.5 during screening), or investigator believes it affects safety evaluation.
- Screening urine test: proteinuria \> 1+;
- Positive urine drug screen (morphine, cannabis) or positive breath alcohol test;
- Subjects who may not be able to complete the trial for other reasons or who the investigator believes should not be included.
