About this study

Official title: A Prospective, Open-label, Multicenter Study of Lamivudine Extending Therapy in Chronic Hepatitis B Patients After 3-year of Oral Antiviral Agents

Current treatment guidelines indicate that oral antiviral agents for HBeAg-positive chronic hepatitis B virus infection (CHB) can be stopped if the patient has undergone HBeAg seroconversion with HBV-DNA loss measured at two consecutive occasions at least 6 months apart (primary treatment endpoint). Stopping treatment can be considered if undetectable HBV-DNA has been documented on three separate occasions 6 months apart in HBeAg-negative patients. However, oral antiviral drugs currently approved for the treatment of CHB have relatively limited sustained long-term efficacy and a large proportion of patients will suffer from HBV recurrence after stopping treatment.

Read the detailed description

The purposes of this study are:

  1. To evaluate the long-term efficacy of Lamivudine extending therapy in CHB patients who received at least 3-year of oral antiviral agents.
  2. To evaluate the long-term outcomes and predictive factors of Lamivudine extending therapy in CHB patients who received at least 3-year of oral antiviral agents.

A prospective, open-label, multicenter study will enroll 500 treatment-naïve CHB patients who received at least 3-year of oral antiviral agents. With their voluntary decision after consultation, 250 patients will receive Lamivudine extending therapy for 5 years and the other 250 patients will receive follow-up and serve as controls. The primary outcome measurement is HBV DNA recurrence, whilst the secondary outcome measurement is liver-related outcomes and associated predictive factors

What is being measured

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

  1. Rate of HBV DNA recurrence

    Measured: up to 12 months

Secondary outcomes (3)
  1. Associated predictive factors of HBV DNA recurrence

    Measured: up to 12 months

  2. Rate of drug resistant mutation

    Measured: up to 12 months

  3. Rate of clinical relapse in Group B (non-intervention)

    clinical relapse means HBV DNA>2000 IU/mL plus ALT > 2 fold upper limit of normal (ULN) in end of entecavir (ETV) normal alanine aminotransferase (ALT) or 2 fold elevation in end of ETV abnormal ALT patients

    Measured: up to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lamivudine in people with Chronic Hepatitis B, run by Kaohsiung Medical University Chung-Ho Memorial Hospital at 1 site in Taiwan.

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 4 inclusion and 16 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: status not confirmed, as of the sponsor's last update on 13 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact Wan-Long Chuang (waloch@kmu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of HBV DNA recurrence (time frame: up to 12 months). 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 13 Jan 2015.
