研究目的:

本研究的主要目标是对比孕妇在接受富?酸丙酚替诺福?治疗或富?酸替诺福??吡呋酯治疗,并且在分娩后为婴?接种?肝疫苗和乙肝免疫球蛋白后,乙型肝炎的?婴传播率差异。我们定义乙型肝炎的?婴传播率为婴?在 28 周龄时?清 HBV DNA>20 IU/mL且HBsAg阳性的婴?占实验组中总出?婴?的?例。 此外,本研究还将对比围产期内使?富?酸丙酚替诺福?和富?酸替诺福??吡呋酯治疗后,?亲所?的婴?中先天缺陷/畸形的发?率以进行药物安全性的研究。  

Objectives of Study:

The main objective of this study is to compare the mother-to-infant transmission rates of hepatitis B between pregnant women receiving treatment with tenofovir alafenamide and those receiving treatment with tenofovir disoproxil fumarate, after administering the hepatitis B vaccine and hepatitis B immunoglobulin to their infants at birth. We define the mother-to-infant transmission rate of hepatitis B as the proportion of infants who are HBsAg positive and have serum HBV DNA >20 IU/mL at 28 weeks of age among all live births in the experimental group. Additionally, this study will also compare the incidence of congenital defects/malformations in infants born to mothers treated with tenofovir alafenamide and tenofovir disoproxil fumarate during the perinatal period to assess drug safety.

随机方法(请说明由何人用什么方法产生随机序列):

本研究将使用由随机统计师使用SAS 9.4或以上版本软件,用中心分层区组随机方法生产受试者随机序列,并使用Gooclin IRT随机系统(V1.1.4)对患者进行分组。 受试者签署知情同意书之后,可在随机系统新增该受试者信息,当通过入排筛选,筛选成功后,可在随机系统进行随机入组操作,系统分配随机号和治疗组别,当受试者分娩后,研究者需要在系统上操作二次随机,系统分配继续治疗或者停止治疗。 入组后,A 组(实验组)患者将在基线访视时接受 TAF 治疗(每日口服 25mg 片剂),B 组(对照组)将接受 TDF 治疗(每日口服 300mg 片剂),分娩后,各组产妇将会在本组内再次随机分配,要么立即停止抗病毒治疗,要么继续维持 12 周的当前治疗(分配比例为 1:1)。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study will use SAS 9.4 or higher software, employed by a random statistician, to generate a random sequence of subjects using a central stratified block randomization method, and will group patients using the Gooclin IRT random system (V1.1.4). After the subjects sign the informed consent form, their information can be added to the random system. Once they pass the inclusion and exclusion screening, they can be randomly assigned in the system, which will allocate a random number and treatment group. After the subjects give birth, the researchers need to perform a second randomization in the system, which will determine whether to continue or stop treatment.After enrollment, patients in Group A (experimental group) will receive TAF treatment (25 mg oral tablet daily) at baseline visits, while Group B (control group) will receive TDF treatment (300 mg oral tablet daily). After giving birth, mothers in each group will be randomly assigned again within their group to either immediately stop antiviral treatment or continue with the current treatment for 12 weeks (allocation ratio of 1:1).
