简要总结
The goal of this intervention research is to learn about the safety and tolerability of 162 with a single ascending dose in subjects with chronic hepatitis B virus (HBV) infection.
详细描述
This is a multi-center, randomized, double-blind and placebo-controlled dose escalation study design.
The dose-escalation stage will be conducted sequentially at 3 dose cohorts, which are 50 mg in the pre-test, 75 mg and 100 mg in the formal test.
Two subjects with chronic HBV infection will be enrolled in the 50 mg dose cohort and all will be given the investigational product 162.
Four subjects with chronic HBV infection will be enrolled in the 75 mg and 100 mg dose cohorts, respectively. Subjects in each cohort will be randomized 3:1 to receive a single ascending dose of 162 or placebo.

入选标准
- •Able and willing to provide written informed consent and to comply with the study protocol according to ICH and local regulations.
- •Positive serum HBsAg and/or HBV DNA status for > 6 months prior to screening (two documented positive HBsAg and/or HBV DNA tests at least 6 months apart, one of which is at screening) or previous liver biopsy results with chronic HBV infection.
- •On Nucleos(t)ide analogs therapy for at least 3 months without an interruption of 7 or more consecutive days before the screening, and expected to remain on the same Nucleos(t)ide analogs for the duration of study participation.
- •500 ≤ HBsAg ≤ 3,000 IU/mL, HBV DNA ≤ 20 IU/mL and ALT ≤ 3×ULN.
- •A male subject must agree to use adequate contraception from screening through at least 24 weeks after the dose of investigational product. Refer to Section 5.5 for more information on highly effective methods of contraception.
- •Women of childbearing potential must have a negative pregnancy test prior to the dosing administration, and agree to use adequate contraception from screening through at least 24 weeks after the dose of investigational product. A female subject of non-childbearing potential will have had at least 12 continuous months of natural (spontaneous) amenorrhoea, follicle stimulating hormone (FSH) level > 40 mIU/mL at screening, and an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms); or have had surgical bilateral oophorectomy, hysterectomy or bilateral tubal ligation beyond 6 weeks prior to screening. Refer to Section 5.5 for more information on highly effective methods of contraception.
排除标准
- •Patients who had history of anaphylaxis against the active ingredients or excipients of the investigational product
- •History of allergic reactions to monoclonal antibodies or antibody fragments.
- •History or presence of clinical significant liver disease other than chronic HBV infection (e.g., autoimmune hepatitis, alcoholic liver disease, non-alcoholic steatohepatitis).
- •Patients who have impaired cardiac function or clinically significant cardiac diseases, including any of the following: New York Heart Association class III-IV for cardiac insufficiency； Patients with poorly controlled arrhythmia: QTc interval > 480 ms calculated by Fridericia's formula, or congenital syndrome of prolonged QT interval; Any of the following within 6 months prior to the screening: myocardial infarction, severe or unstable angina, congestive heart failure, cerebrovascular accident (including transient ischemic attack), symptomatic pulmonary embolism or other clinically significant thromboembolic disease, or coronary artery bypass graft; Patients with other clinically significant cardiovascular disease who were assessed as unsuitable for this study by the investigator.
- •Patients with uncontrolled hypertension (systolic blood pressure ≥ 150 mm Hg and/or diastolic blood pressure ≥ 100 mm Hg) or previous hypertensive crisis or hypertensive encephalopathy.
- •Patients with other active infections other than HBV infection requiring continual treatment with antibiotics or antivirals (except for clinically insignificant temporary infection such as cold), or positive for hepatitis C virus (HCV) or human immunodeficiency virus (HIV) antibodies at screening.
- •Patients with history of hepatitis A virus (HAV), hepatitis D virus (HDV) or hepatitis E virus (HEV).
- •Patients with history of malignant tumor within 5 years except cured basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ of uterine cervix.
- •History or presence of immune-mediated diseases, including but not limited to idiopathic thrombocytopenic purpura, systemic lupus erythematosus, rheumatoid arthritis.
- •Liver biopsy, Fibroscan or equivalent test obtained within the past 6 months demonstrating liver with evidence of progressive fibrosis or cirrhosis ( Metavir 3, recommended cut-off for fibroscan 8.5 kPa).
- •Evidence of liver cirrhosis or decompensated liver disease such as Child-Pugh Class B or C, ascites, esophageal or gastric varices, hepatic encephalopathy or portal hypertension.

- •Those who received blood transfusion, albumin, recombinant human thrombopoietin, or colony-stimulating factor therapy within 2 weeks prior to screening
- •Patients who have not sufficient baseline organ function and whose laboratory data meet the following criteria at enrollment: Absolute neutrophil count (ANC) < 2.0×109/L; Serum albumin < 35 g/L; Total bilirubin > 1.5×ULN; International normalized ratio (INR) > 1×ULN; Hemoglobin < 100 g/L; Platelets < 80×109/L; Creatinine clearance < 50 mL/min.
- •Patients who had received an immunosuppressant, immunity-modifying drug (e.g., interferon, thymosin agents), cytotoxic chemotherapy that can affect their immune system, or radiation therapy within 6 months prior to the dosing of investigational product, except for the following treatments: a) topical or inhaled corticosteroids; b) short-term (treatment duration up to 7 days) use of systemic glucocorticoids for prevention or treatment of non-autoimmune allergic diseases.
- •Those who have received live or attenuated vaccines (e.g., measles, mumps, rubella, varicella, yellow fever, rabies, BCG, typhoid vaccine, etc.) within 4 weeks before screening, or any covid-19 vaccine within 2 weeks before screening.
