Brief Summary:
A multiple-center, open-label, Phase II clinical trial to evaluate the safety and the efficacy of HLX10 in chronic hepatitis B patients.

Condition or disease Intervention/treatment Phase
Hepatitis B, Chronic Drug: Recombinant anti-programmed death-1 (PD-1) humanized monoclonal antibody Drug: Nucleoside/nucleotide analogues Phase 2

Detailed Description:

This study is multiple-center, open-label, Phase II clinical trial and uses Simon's Two-Stage Optimal design. Subjects with chronic hepatitis B (CHB) will be enrolled sequentially and receive up to 3 doses of HLX10 at 1 mg/kg for four weeks apart.

First six subjects will be enrolled in the safety run-in period. If there are no serious adverse events noticed in these 6 subjects up to 6 weeks after the last infusion of HLX10, additional 11 subjects will be enrolled. These 17 subjects (6+11) will be evaluated for efficacy. In the second stage of trial, 27 additional subjects will be enrolled. Total 44 subjects [stage I (n=17) + stage II (n= 27) = total (n=44)] will be accrued in this study.

Ages Eligible for Study:   18 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Eligible subjects must be 18 years of age or older or per local regulations and younger than 65 years.
  2. Subjects with chronic hepatitis B infection with serum HBsAg level > 100 IU/mL. [Chronic hepatitis B infection/carrier status must be confirmed by at least two laboratory results of persistent hepatitis B virus (HBV) infection (positive HBs antigen or HBV DNA) collected 6 months apart before the first infusion of HLX10.]
  3. Achieved viral suppression, defined as: HBV DNA level (checked within 4 weeks before the first dose of HLX10) lower than 2000 IU/mL.
  4. Subjects must be either (1) under nucleoside/nucleotide analogues (NAs) therapy and has achieved viral suppression at the time of study entry or (2) who currently are not taking anti-viral NAs but be able and willing to take one of the designated NAs for a duration of 14 to 22 weeks (2 weeks before the first dose of HLX10, up to 8 weeks during treatment, 12 weeks after the last dose of HLX10).
  5. HBe antigen (checked within 4 weeks before the first dose of HLX10) must be negative.
  6. Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1 at the time of study entry.
  7. Able to provide informed consent.
  8. Adequate hematologic functions, as defined by: a normal white blood cell count, a normal absolute neutrophil count; a hemoglobin level ≥ 10 gm/dL and a platelet count ≥ 100,000/mm3.
  9. Adequate hepatic function defined by: a normal total bilirubin level, alanine transaminase (ALT) level and a prothrombin time of INR < 1.5 times normal.
  10. Adequate renal function, as defined by the creatinine clearance rate ≥ 50 mL/minute calculated using Cockcroft-Gault formula. In subject with extreme body weight (BMI < 18.5 or > 30), estimated glomerular filtration rate (eGFR) > 50 mL/min calculated using Modification of Diet in Renal Disease (MDRD) formula is acceptable.
  11. Adequate cardiac function defined as left ventricular ejection fraction (LVEF) ≥ 50% measured by multigated acquisition (MUGA) scan or cardiac ultrasound.
