Outcome Measures

Primary Outcomes (2)

  • The data on its tolerability and safety in HBeAg+ pregnant woman with HBV DNA>6log10 copies/Ml during late pregnancy and infants

    perinatal to 28 weeks after infant delivery

  • Its efficacy in the reduction of HBV vertical transmission rate

    perinatal to 28 weeks after infant delivery

Secondary Outcomes (1)
