A Two-year Study of Telbivudine in HBeAg Negative Hepatitis (STEN)

October 22, 2017 updated by: Chao-Shuang Lin, Third Affiliated Hospital, Sun Yat-Sen University

A Two-year, Open-label, Virological Response Adaptive Design, Multicenter Study to Evaluate Efficacy of Telbivudine in HBeAg Negative Adult CHB Patients With Roadmap Strategy

Based on GLOBE study supplying predictability analysis results, ROADMAP strategy provides an individualized telbivudine treatment roadmap strategy designed to achieve optimal viral suppression and low resistance rate in patients with chronic hepatitis B(CHB), which includes adding ADV treatment at different time points according to individual patient response. China CHB Guidelines (China Medical Association 2010) make impress on and confirm LDT ROADMAP strategy particularly, which may be a large potential to expand the naïve patients. We are lack of optimal model in HBeAg(-). In China HBeAg(-) is around 38% of total CHB patients. In GLOBE study, LdT treatment against HBeAg(-) patients with HBV DNA <7log showed a good 2 year efficacy, but we still look forward to more efficient treatment and lower resistance rate. This study complies with the principle of individualized therapy recommended and ethical principles. It is expected that this study design with individualized treatment approach may improve efficacy and lower the resistance rates. In addition, it will provide important information on how to bring greater benefits to patients with CHB.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is an open-label, multicenter, PCR response adaptive clinical study design, with intensification of treatment (addition of adefovir to telbivudine treatment) depending on HBV DNA level at week 24. All patients commence with Telbivudine 600mg daily. At week 24 they will be divided into 2 Groups according to virological response. Patients with PCR detectable HBV DNA will add on ADV(Group I). Patients with PCR undetectable HBV DNA(Group II)will continue telbivudine monotherapy. ADV will not be added on unless viral breakthrough occurs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No
