Purpose
Infants of hepatitis B virus (HBV)-infected mothers with positive hepatitis B e antigen (HBeAg) have an increased risk of becoming infected with HBV. This study will determine whether telbivudine among both hepatitis B surface antigen (HBsAg) and HBeAg positive pregnant women during the third trimester, in addition to standard immunoprophylaxis in infants, will be more effective than standard immunoprophylaxis alone at preventing HBV infections in these infants.

| Official Title: | Telbivudine in the Third Trimester of Pregnancy to Prevent Mother-to-infant Transmission of HBV |
- HBV serologic markers and alanine transaminase (ALT) levels in infants [ Time Frame: 10 months after birth ] [ Designated as safety issue: No ]HBsAg and HBeAg are tested in umbilical blood and peripheral blood collected at the age of 10 months respectively. ALT is measured at 10 months old.
- HBV DNA quantification and ALT levels in mothers [ Time Frame: Up to 10 months postpartum ] [ Designated as safety issue: No ]HBV DNA and ALT levels in the pregnant women are measured before taking telbivudine, at birth, 1-2 months after stopping the drug, and 10 months postpartum.
- Women and infants with adverse events [ Time Frame: Up to 10 months after delivery/birth ] [ Designated as safety issue: Yes ]Adverse events in pregnant women during pregnancy, complications at delivery and postpartum, Apgar score, newborn infant deformity, infant growth and development will be recorded during the study period (up to 10 months after delivery/birth).

Experimental: Telbivudine
HBsAg- and HBeAg-positive pregnant women at 28-32 weeks of gestation start to orally take telbivudine (600 mg/day) until 4 weeks after delivery. Newborn infants receive standard immunoprophylaxis.

Drug: Telbivudine
HBsAg- and HBeAg-positive pregnant women at 28-32 weeks of gestation are given with telbivudine (oral 600 mg/day) until 4 weeks after delivery. Newborn infants are administered 100-200 IU HBIG within 12 hours after birth and vaccinated against hepatitis B with yeast recombinant hepatitis B vaccine (10 µg) at 0, 1, and 6-month schedule. HBV DNA and ALT levels are measured before the use of telbivudine, at delivery, and 1-2 months after stopping the drug. HBV serological markers, including HBsAg, anti-HBs, and anti-HBc, HBeAg and anti-HBe are tested in infants at age of 7-12 months.

No Intervention: Control
Infants of HBsAg- and HBeAg-positive women who are not treated with telbivudine and any other antiviral agents serve as controls. The infants are administered standard immunoprophylaxis against mother-to-infant transmission of HBV, 100-200 IU hepatitis B immunoglobulin (HBIG) within 12 hours after birth and three doses hepatitis B vaccine at 0, 1 and 6-month schedule.

Detailed Description:
Infants of HBV-infected mothers with positive HBeAg have an increased risk of becoming infected with HBV. Standard immunoprophylaxis against mother-to-infant transmission of HBV includes administration of hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine; however, approximately 5-15% of the infants are not protected despite having received these preventive measures. It is reported that antiviral prophylaxis among HBV-infected pregnant women can reduce mother-to-infant transmission of HBV. However, more research is needed to obtain the definite conclusion. This study will determine whether telbivudine among HBsAg- and HBeAg-positive pregnant women during the third trimester, in addition to standard immunoprophylaxis in infants, will be more effective than standard immunoprophylaxis alone at preventing HBV infections in these infants.
