What is being measured

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

  1. Number of Patients Achieving Serum HBV DNA Level of <300 Copies/mL (51 IU/mL) at Week 24

    The primary objective of this study was to demonstrate the antiviral efficacy of telbivudine compared to placebo in pediatric patients (2- < 18 years) by determining the percentage of patients achieving serum HBV DNA level of <300 copies/mL (51 IU/mL) at Week 24.

    Measured: Week 24

Secondary outcomes (8)
  1. Number of Patients Achieving HBV DNA< 300 Copies/mL (51 IU/mL) at Week 52 and Week 104

    The antiviral efficacy at Weeks 52 and 104 was to be evaluated by: a) the proportion of patients achieving HBV DNA <300 copies/mL (51 IU/mL) at Week 52 and Week 104; b) the proportion of patients achieving HBV DNA < Lower Limit of Quantification (LLOQ), <1000 copies/ml (or 200 IU/mL), <10,000 copies/ml (or 2 000 IU/mL) and ≥10,000 copies/mL (or 2 000 IU/mL) at Week 24, 52 and 104; c) the proportion of patients achieving Serum HBV DNA reduction from baseline; d) the time to achieve HBV DNA <300 copies/mL (51 IU/mL); e) the proportion of patients with Primary non-response.

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 52, Week 104

  2. Number of Patients Whose Baseline ALTs Were Abnormal and Subsequently Normalized at Week 24, 52 and 104

    The biochemical response at Weeks 24, 52 and 104 was to be evaluated by the proportion of patients whose baseline ALTs were abnormal (defined as ALT >1 x Upper Limit of Normal [ULN]) and subsequently normalized.

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 24, Week 52, Week 104

  3. Number of Patients With HBeAg Loss, HBeAg Seroconversion at Week 24, 52 and 104

    The serological response at Weeks 24, 52 and 104 was to be evaluated by: a) the proportion of HBeAg positive patients at baseline who subsequently have HBeAg loss and HBeAg seroconversion (defined as loss of HBeAg with detectable HBeAb); b) the proportion of HBsAg positive patients at baseline who subsequently have HBsAg loss and HBsAg seroconversion (defined as loss of HBsAg with detectable HBsAb).

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 24, Week 52, Week 104

  4. Number of Patients With HBsAg Loss, HBsAg Seroconversion at Week 24, 52 and 104

    The serological response at Weeks 24, 52 and 104 was to be evaluated by: a) the proportion of HBeAg positive patients at baseline who subsequently have HBeAg loss and HBeAg seroconversion (defined as loss of HBeAg with detectable HBeAb); b) the proportion of HBsAg positive patients at baseline who subsequently have HBsAg loss and HBsAg seroconversion (defined as loss of HBsAg with detectable HBsAb).

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 24, Week 52, Week 104

  5. Number of Patients Achieving a Composite Endpoints (HBV DNA < 300 Copies/mL (51 IU/mL), ALT Normalization and HBeAg Seroconversion) at Week 52 and 104

    The proportion of patients achieving composite endpoints at Week 52 and 104 was to be evaluated by the proportion of patients achieving: a) HBV DNA <300 copies/mL (51 IU/mL); b) ALT normalization and HBeAg seroconversion for HBeAg positive patients only; c) HBV DNA <300 copies/mL (51 IU/mL) and ALT normalization for HBeAg negative patients.

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 52, Week 104

  6. Number of Patients Achieving Cumulative Rate of Virological Breakthrough (VB) at Week 52 and 104

    The assessment of virological breakthrough (VB) was to be evaluated by: a) the cumulative rate of patients with confirmed VB at Week 52 and Week 104; b) the time to VB.

    Due to early termination of the study and limited number of enrolled patients on track to complete 52 weeks of participation (8 patients overall), only descriptive analysis performed at Week 52 and Week 104.

    Measured: Week 52, Week 104

  7. Number of Participants With Treatment Emergent Genotypic Resistance Associated With VB, or in Patients With HBV DNA≥300 Copies/mL (51 IU/mL) at Week 24 and Discontinued From the Study

    Assessment of the presence of treatment emergent genotypic resistance (confirmed by genotypic sequencing) associated with virological breakthrough over the study period, or in patients with HBV DNA≥300 copies/mL (51 IU/mL) at Week 24 and discontinued from the study treatment (or at discontinuation if prior to Week 24 for subjects with at least 16 weeks of LDT treatment)

    Measured: Week 24

  8. Number of Participants With On-Treatments Adverse Events, Serious Adverse Events, and Death

    Evaluation of the safety and tolerability of Telbivudine defined by AEs, SAEs, adverse events of special interest (AESI) (including muscle related events) and death; laboratory evaluations specifically on-treatment and post-treatment ALT flares, incidence and clinical significance of CK elevations; growth and development (linear growth and sexual maturation); development of liver decompensation and/or HCC.

    Only descriptive analysis performed.

    Measured: From first dose of study treatment to 30 days after last dose of study treatment, up to 112 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Telbivudine in people with Chronic Hepatitis B, run by Novartis Pharmaceuticals at 29 sites in 7 countries.

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 5 inclusion and 8 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: stopped early, as of the sponsor's last update on 10 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 29 sites in Romania, Turkey (Türkiye), Ukraine, Bulgaria, Israel and 2 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Patients Achieving Serum HBV DNA Level of <300 Copies/mL (51 IU/mL) at Week 24 (time frame: Week 24). 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 10 Sep 2019.
