About this study

Official title: Nucleoside Analogue in Late Preganancy to Prevent Vertical Transmission of Hepatitis B Virus

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.

Being tested
Telbivudine, Lamivudine
Medical subject headings
Hepatitis B, Persistent Infection, Viremia

What is being measured

The primary outcome is the main question the study is designed to answer.

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

    Measured: perinatal to 28 weeks after infant delivery

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

    Measured: perinatal to 28 weeks after infant delivery

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

    Measured: perinatal to 28 weeks of postpartum

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Telbivudine and Lamivudine in people with Hepatitis B Infection and Chronic Infection, run by Hua Zhang.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2013.
