NCT05808335

Brief Summary

This is a multicenter, randomized, double-blind, parallel group, 48-week follow-up, Phase IIa clinical study. This study has been designed to evaluate the change in HBsAg (log10 IU/mL) after administration of hzVSF-v13 50 mg/dose and hzVSF-v13 200 mg/dose in combination with an oral antiviral agent (Tenofovir or entecavir, including salt-free or salt-modifying drugs) compared to an oral antiviral agent in combination with a placebo (normal saline) in patients with chronic hepatitis B who are stably receiving an oral antiviral agent (Tenofovir or entecavir, including salt-free or salt-modifying drugs) for at least 24 weeks.

Outcome Measures

Primary Outcomes (1)

  • Change in HBsAg from the baseline at 24 weeks (log10 IU/mL)

    Baseline statistics for the changes in HBsAg (log10 IU/mL) from the baseline at 24 weeks shall be presented for each group, and a two-sample t-test or the Wilcoxon rank-sum test shall be performed to test differences of each study group compared to the control group.

    24 weeks

Secondary Outcomes (2)

  • Percentage of subjects with HBsAg loss or seroconversion compared to the baseline at 8, 12, 24 and 48 weeks

    8, 12, 24, 48 weeks

  • Percentage of subjects with HBV DNA lower than the lower limit of quantification (LLOQ) compared to the baseline at 24 and 48 weeks

    24, 48 weeks

Eligibility Criteria

Age19 Years - 64 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Those who have a history of a diagnosis of chronic hepatitis B more than 24 weeks prior to screening and have been maintaining HBsAg positive at screening
  • Those who have an HBV DNA level that is below \<20 IU/mL
  • Those who have been receiving tenofovir (including Tenofovir's salt-free or salt-modifying drugs), or entecarvir (including Entecavir's salt-free or salt-modifying drugs) stably for ≥24 weeks prior to screening and anticipated to maintain the identical drug with equivalent dosage and administration during the clinical trial.
