Brief Summary

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

To determine the optimal time for the Tenofovir treatment of anti-Hepatitis B Virus (HBV) during the pregnancy among women with chronic HBV infection and high HBV DNA load. This is a randomized, open-label, three-arms, parallel-controlled clinical trial. Pregnant women with high HBV load and normal liver function will be treated with tenofovir during the middle or late stage of pregnancy, started from 24th gestational week, 28th gestational week and 32th gestational week through 1 month postpartum, respectively. The HBV DNA load at 40th gestational week of mothers, the intrauterine HBV infection rate of infants will be compared across the three groups.

Detailed Description

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

Tenofovir Disoproxil Fumarate is a American Food and Drug Administration (FDA) pregnancy class B drug. To determine the optimal time for the tenofovir treatment during the pregnancy among women with chronic HBV infection and high HBV DNA load. Pregnant women with high HBV DNA load and normal liver function at second trimester will be randomized into three treatment groups at the 20th week of gestation and treated with tenofovir from 24 weeks, 28 weeks and 32 weeks to 1 month postpartum, respectively. The blood will be drawn at 24 weeks, 28 weeks, 32 weeks, 36 weeks and the delivery, respectively and the HBV DNA load and liver functions will be tested. The status of HBV infection for infants will be observed at 1st month, 7th month and 12th month after the babies were delivered. The HBV DNA load at 40th gestational week of mothers, the intrauterine HBV infection rate of infants and safety outcomes will be compared across the three groups.
