Brief Summary

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

To investigate the safety and efficacy of tenofovir alafenamide (orally 25 mg per day) treated in inactive chronic hepatitis B virus (HBV)-infected pregnant women with high viral load from the late pregnancy until the delivery date or postpartum 1 month.

Detailed Description

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

The investigators intend to include 240 inactive chronic hepatitis B virus (HBV)-infected pregnant women who have an HBV DNA level higher than 200,000 IU per milliliter. Participants will be randomly assigned, in a 1:1 ratio, to receive tenofovir alafenamide (orally 25 mg per day) from the late pregnancy until the delivery date or postpartum 1 month. All the infants will receive standard immunoprophylaxis (100 IU of hepatitis B immunoglobulin and 10 μg of hepatitis B vaccine within 12 hours of birth; the second injection of 10 μg of HBV vaccine will inject at 1 month; and the third dose of 10 μg of HBV vaccine will give at 6 months). The pregnant women and their infants will be followed until postpartum month 7. The primary outcomes are the birth defects and rates of perinatal transmission of HBV. During the prenatal period or the postnatal period up to 7 months of age, cases of a structural defect in newborns or infants were reported as birth defects. The rate of perinatal transmission was defined as the proportion of infants who are positive for hepatitis B surface antigen at 7 months of age. The secondary safety outcomes are the occurrence of maternal or infant adverse events during the study period. Maternal safety evaluations mainly include any adverse events and complications, hepatitis B virologic breakthrough, alanine aminotransferase flare, and so on. Infant' safety profiles mainly included Apgar scores at 1 minute, any abnormal conditions during the study period, and anthropometric indexes at birth and 7 months of age. The secondary efficacy outcomes are the percentages of mothers with an HBV DNA level of less than 200,000 IU per milliliter just before or at delivery, and the hepatitis B e antigen and surface antigen loss or seroconversion in mothers at postpartum month 7.
