Study summary

To explore the antiviral effect of nucleoside analogue in late pregnancy and the safety of the antiviral drug to fetus.To establish the best therapy strategy to pregnant women with high level of HBV DNA.

Read the detailed description

Telbivudine and Lamivudine,a preganancy category B medication,reduces HBV DNA and normalizes serum ALT in chronic hepatitis B patients with few adverse effects.Two aspects on the drug use in pregnancy will be evaluated prospectively in this study.

Inclusion criteria

HBeAg+CHB pregnant woman gestational age 28 weeks >log10 copies/ml

Exclusion criteria

Exclusion Criteria:

co-infection with hepatitis A,C,D,E or evidence of hepatocellular carcinoma decompensated liver disease or significant co-morbidity concurrent treatment with immune-modulators,cytotoxic drugs,or clinical signs of threatened miscarriage in early prenancy evidence of fetal deformity by ultrasound examination the biological father of the child had CHB

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. The data on its tolerability and safety in HBeAg+ pregnant woman with HBV DNA>6log10 copies/Ml during late pregnancy and infants

    Time frame: perinatal to 28 weeks after infant delivery

  2. Its efficacy in the reduction of HBV vertical transmission rate

    Time frame: perinatal to 28 weeks after infant delivery

Secondary outcomes

  1. Maternal DNA reduction,ALT normalization, and loss/seroconversion of HBeAg or HBsAg

    Time frame: perinatal to 28 weeks of postpartum
