  Purpose

Immunoprophylaxis failure of Hepatitis B (HBV) leading to vertical transmission remains a concern and has been reported in approximately 8-15% of infants born to HBeAg positive mothers with high levels of HBV DNA. Maternal HBV DNA > 6log10 copies/mL is the major risk for the mother-to-child transmission. Prior studies have shown that antiviral therapy including lamivudine or telbivudine use during late pregnancy can safely reduce the rate of vertical transmission in this special population compared to untreated patients.

Tenofovir Disoproxil (TDF), a pregnancy category B medication, reduces HBV DNA and normalizes serum ALT in chronic hepatitis B patients (CHB) with few adverse effects. Two aspects on tenofovir use in pregnancy will be evaluated prospectively in this study:

  1. The data on its tolerability and safety in HBeAg+ pregnant women with HBV DNA > 6log10 copies/mL during late pregnancy and infants
  2. Its efficacy in the reduction of HBV vertical transmission rate

Primary Outcome Measures:
  • Assessment of the safety of TDF, measure the number of participants and paired infants with adverse events [ Time Frame: From the date of randomization until 28 weeks of postpartum. ] [ Designated as safety issue: Yes ]
  • Measure the number of infants who have HBV infection at the age of 28 weeks [ Time Frame: From the date of birth to age of 28 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Measure the number of patients with ALT normalization at the end of the study compared to the baseline [ Time Frame: From the date of randomization until 28 weeks of postpartum. ] [ Designated as safety issue: Yes ]
  • Measure maternal HBV DNA reduction during the study period when compared to the baseline [ Time Frame: From the date of randomization until 28 weeks of postpartum. ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 200
Study Start Date: December 2011
Estimated Study Completion Date: September 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: HBIG, HB vaccine
Provide standard of care to mothers and standard immunoprophylaxis to their infants
Experimental: TDF treatment arm
tenofovir from 30-32 weeks of pregnancy to the week 4 of postpartum for mothers and standard immunoprophylaxis to their infants
Drug: TDF treatment
About 100 mothers treated with tenofovir from 30-32 weeks of pregnancy to the week 4 of postpartum, then observed to the end of the study at post-partum week 28, paired infants received standard HBV prophylaxis.
Other Name: Viread, Tenofovir, TDF, Hepatitis B-IgG, Hepatitis B vaccine

Detailed Description:

Eligible mothers will be randomized (1:1)to either TDF-treated group or untreated group with about 100 subjects in each arm. The treatment group will receive TDF starting at week 30-32 of gestation until week 4 post-partum; follow up will continue until post-partum of week 28 and infants age of 28 weeks. Untreated group will receive the standard of care with similar follow-up schedule as the treatment group
