Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the efficacy and safety of Telbivudine in pregnancy for the prevention of HBV perinatal transmission in highly viraemic mothers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the present study, we evaluated the effect of telbivudine given during the second and third trimesters of pregnancy to highly viremic, HBV DNA-positive mothers on maternal HBV DNA and HBeAg levels prior to delivery and the rate of vertical transmission of HBV to infants who received passive-active immunoprophylaxis. Additionally, we investigated the timing of the administration of telbivudine on reducing the risk of perinatal transmission and the safety of telbivudine during pregnancy.

Telbivudine

Drug administration and follow up: the subjects in Telbivudine group start dosing Telbivudine orally at 20-32 gestational weeks, with 600 mg daily, continue to one month after delivery.And their newborns are given HBIG 200IU by injection immediately after born and at day 15. They are also injected with genetically engineered HB vaccine 20ug respectively at age of 0, 1 and 6 months.
