  • 2. HLA-A*02:01 positive (central laboratory testing)
  • 3. Documented evidence of CHB based on one of the following:
  • a. Positive HBsAg and HBV DNA at least 6 months prior to the screening visit;
  • b. Historical liver biopsy consistent with CHB infection available.
  • 4. If previously HBeAg-positive, participants must be HBeAg-negative at the screening visit and have historical HBeAg-negative status >3 months prior to the screening visit available for review.
  • 5. Have been receiving entecavir and/or tenofovir (including tenofovir alafenamide) for = 12 months prior to screening and are willing to continue.
  • 6. HBV DNA negative (below the LLOQ) at screening
  • 7. Quantitative HBV surface antigen = 1000 IU/mL at the screening visit.
  • Participants with HBsAg levels = 1000 IU/mL and = 3000 IU/mL may be eligible after consultation with, and approval by, the Sponsor's Medical Monitor.
  • 8. All participants must have no history of liver cirrhosis AND prior assessment of fibrosis demonstrating non-cirrhotic status at screening as defined by one of the following:
  • a. Liver biopsy demonstrating a Metavir Fibrosis Score of F0-2 (or equivalent);
  • b. Fibroscan® result of < 9 kPa.
  • NOTE: A confirmatory Fibroscan® is required within 6 months prior to Day 1.
  • 9. Liver imaging confirming absence of clinically significant abnormalities is required within 6 months prior to Day 1.
  • 10. Male and female participants of childbearing potential who are sexually active with a nonsterilized partner must agree to use highly effective methods of birth control from the trial screening date until 3 months after the final dose of the study intervention or longer if required by local regulations; cessation of birth control after this point should be discussed with a responsible physician. *Male participants are not allowed to donate sperm from the time of enrollment until 3 months post-administration of study interventions or longer if required by local
  • regulations.
  • *Female participants must refrain from egg donation during the course of the study
  • 11. Capable of giving signed informed consent
  • Are the trial subjects under 18? no
  • Number of subjects for this age range: 0

排除标准

  • Medical Conditions
  • 1. Known co-infection with any of the following:
  • b. Hepatitis C virus OR
  • c. Hepatitis D virus
  • 2. Changes in HBeAg status within 3 months prior to the screening visit
  • 3. Known HBV genotype A
  • 4. History of HCC
  • 5. Gilbert's syndrome
  • 6. Any known pre-existing medical or psychiatric condition that could interfere with the participant's ability to provide informed consent or participate in study conduct, or that may confound study findings
  • 7. Significant immunosuppression from, but not limited to immunodeficiency conditions such as common variable hypogammaglobulinemia
  • 8. Evidence of active or suspected malignancy, or a history of malignancy = 3 years prior to the screening visit (except adequately treated carcinoma in situ and basal cell carcinoma of the skin). NOTE: Participants under evaluation for malignancy are not eligible
  • 9. Known or suspected hypersensitivity or previous severe reactions to any of the constituents of IMC-I109V, or the drugs used in the pretreatment regimen (eg, dexamethasone, ibuprofen and paracetamol)
  • 10. Pregnant or lactating women
  • Prior/Concomitant Therapy
  • 11. Receiving or planning to receive systemic immunosuppressive medications during the study or = 2 months prior to Day 1, including but not limited to prednisone > 10 mg/day (or equivalent), methotrexate, cyclosporine, or interferon. NOTE: Local steroid therapy are allowed (eg,inhaled, otic, ophthalmic, or intra-articular medications).
  • Prior/Concurrent Clinical Study Experience
  • 12. Use of any live vaccines against infectious diseases within 4 weeks of the first planned administration of study intervention or use of any non-live vaccines against infectious diseases within 2 weeks of the first planned administration of study intervention.
  • 13. Treatment with any investigational drug or enrollment in any other clinical study = 6 months prior to Day 1, or at any time during participation in the study
  • Laboratory Exclusion Criteria
  • 14. If any of the laboratory exclusion criteria are met, then the site may have the participant retested. If a single value is within ±10% of the listed laboratory exclusion criterion value upon retest, and the value is considered to be not clinically significant by the physician investigator, the participant may be considered for enrollment.
  • Other Exclusions
  • 15. Clinical diagnosis of substance abuse with alcohol, narcotics, or cocaine = 12 months prior to the screening visit, except for those participants monitored in an opioid substitution maintenance program
  • 16. Poor venous access that precludes routine peripheral blood sampling or intravenous (IV) infusion required for this study
