Summary

Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.

Conditions

  • Hepatitis B Virus (HBV)

Interventions

BIOLOGICAL

T101 Group

Single Dose (SD) Cohort: In each group, 3 of chronic hepatitis B patients will be subcutaneously injected with different dose level of T101 at 1.0E+9VP (Group1)/1.0E+10VP (Group2)/1.0E+11VP (Group 3) on D1. Multiple Dose (MD) Cohort: In each group, 9 of chronic hepatitis B patients will be subcutaneously injected with different dose level of T101 at 1.0E+10VP (Group1)/1.0E+11VP (Group2) on D1, D8, D15.

BIOLOGICAL

Placebo Group

Single Dose (SD) Cohort: 3 of chronic hepatitis B patients will be subcutaneously injected with placebo on D1. Multiple Dose (MD) Cohort: 6 of chronic hepatitis B patients will be subcutaneously injected with placebo on D1, D8, D15.
