Brief Summary

Immunoprophylaxis with two hepatitis B vaccinations following the hepatitis B immune globulin (HBIg) and hepatitis B vaccine at birth is largely effective in protecting infants from hepatitis B virus (HBV) infection. However, hepatitis B infection due to immunoprophylaxis failure often occurs in approximately 10% of infants who are born to highly viremic mothers with HBeAg-positive. Maternal HBV DNA \> 200,000 IU/mL is the major independent risk for mother-to-child transmission (MTCT). A recent randomized controlled trial has shown that Tenofovir Disoproxil Fumarate (TDF) use during the third trimester of pregnancy could safely reduce the rate of MTCT with few adverse effects when combined with the administration of the standard immunoprophylaxis to the infants. However, HBIg is expensive and not available in many developing countries, resulting approximately 30% of infant infection when they received only HBV vaccination. The present study aims to investigate if highly viremic mothers who are treated with TDF from the second trimester to delivery in combination of infant's standard series of HBV vaccinations (omission of HBIg) have a comparable MTCT rates, when compared to those of mothers who receive TDF at the third trimester in combination of infant's standard HBV vaccinations and a birth dose of HBIg.

Outcome Measures

Primary Outcomes (1)

  • Assessment on the proportion of infants who are infected with hepatitis B at the age of 28 weeks in the two groups

    Compare MTCT rates between the two study groups and demonstrate non-inferiority in efficacy. MTCT rate is defined as the proportion of infants with serum HBV DNA \>20 IU/mL and/or HBsAg positivity at 28 weeks of age.

    From the date of birth to age of 28 weeks.

Secondary Outcomes (5)

  • Assessment on congenital defects and/or malformation rates in each infant group for comparison

    From the date of birth to age of 28 weeks.

  • Assessment on the reduction of maternal HBV DNA levels at delivery

    From the date of randomization until delivery.

  • Maternal serological outcomes during the study: Percentage of mothers who loss/seroconversion of HBsAg or/and HBeAg during the study

    From the date of randomization until postpartum week 28.

  • Adverse events of both mothers and infants

    From the date of screening until postpartum week 28.

  • Tolerability of TDF therapy: Percentage of mothers who discontinue on TDF therapy due to the adverse event(s) during the study

    From the date of randomization until delivery.

Study Arms (2)

Group A

EXPERIMENTAL

This is the experimental group. Participating mothers will receive Tenofovir Disoproxil Fumarate (TDF) 300 mg oral daily, starting at gestational weeks 14-16 and continue until delivery. The mothers will be followed together with their infants until postpartum week 28. Infants will receive hepatitis B vaccine at birth and additional hepatitis B (HBV) vaccine at the age of week 4 and week 24. HBIg will be omitted for the infants in this group.

Drug: Tenofovir Disoproxil Fumarate (TDF) 300 mg oral daily.

Group B

ACTIVE COMPARATOR

This is the comparative group. Participating mothers will receive Tenofovir Disoproxil Fumarate (TDF) 300 mg oral daily, starting at gestational weeks 28 and continue until delivery. Patients in group B will have similar follow-up schedules as those in the experimental group. Infants will receive hepatitis B vaccine plus HBIg at birth and additional hepatitis B vaccine at the age of week 4 and week 24.

Drug: Tenofovir Disoproxil Fumarate (TDF) 300 mg oral daily.

Interventions

All mothers will receive TDF therapy. However, group A will initiate TDF at the gestational week of 14-16, while group B will initiate TDF at the gestational week of 28. All infants will receive a series of three hepatitis B vaccines (at birth, age of weeks 4 and 24). In addition, the infants in the group B will receive HBIg injection at birth.

Also known as: HBIg 200 IU im for infants in the group B, HBV vaccine 10 ug im for all infants
