About this study

Official title: A Randomized, Open Label, Phase IV, Multicenter Study for Efficacy and Safety of Lamivudine Versus Entecarvir Therapy in HBV-related Advanced Liver Disease Patients With High Viral Load and Normal or Slightly Elevated Transaminase

This is a randomized, open label, phase IV, multicenter study for efficacy and safety of lamivudine versus entecarvir therapy in HBV-related advanced liver disease patients with high viral load and normal or slightly elevated transaminase.

Read the detailed description

Currently, treatment guidelines for the management of chronic hepatitis B (CHB) recommend that patients with serum HBV DNA > 105 copies/ml and elevated ALT levels greater than two times the upper limit of normal (ULN) are obvious candidates for antiviral therapy. Guidelines also suggest that antiviral therapy be considered in CHB patients with high viral load, if a biopsy shows significant liver disease despite ALT ≤ 2× ULN. Data from recent trials in hepatitis B patients who present with normal to minimally elevated ALT (≤ 2× ULN) indicate that significant hepatic pathology could still be found. Serum ALT level may not accurately predict activity of liver damage. ALT is a poor predictor of outcome and therefore is not a suitable criterion for antiviral therapy in chronic hepatitis B infection. Also, a recent large randomized controlled clinical trial comparing lamivudine maintenance and placebo in advanced fibrosis (Ishak fibrosis score ≥ 4) suggests that sustained viral suppression with antiviral therapy is linked to reduced risk for disease progression.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Entecavir and Lamivudine in people with Hepatitis B, Chronic, run by Yonsei University at 1 site in South Korea.

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 11 inclusion and 10 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 16 Dec 2010. 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 South Korea. 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?

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?

Time to disease progression as defined by the first occurrence of any of the cirrhosis compolications (time frame: 5 years). 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 16 Dec 2010.
