Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the trial is to investigate whether the add-on of pegylated interferon alfa-2a to a continued treatment with nucleos(t)ide analogues increases the percentage of patients who have significant decrease (≥1log10) of HBs-antigen after 48 weeks.
    E.2.2Secondary objectives of the trial

    - Adverse events
    - Vital signs, physical examination
    - Laboratory test abnormalities
    - Laboratory test value changes over time
    •To identify biological variables predicting HBs antigen decrease:
    - viral genotype
    - kinetic of HBs antigen level
    • To determine the effect of pegylated interferon on frequency and functional properties of HBV-specific cytotoxic and regulatory T-cells in responder and nonresponder patients
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Chronic hepatitis B, HBe antigen negative
    • Treatment with a stable oral antiviral treatment (not containing telbivudine) and a fully suppressed viral load for at least 12 months (below limit of detection in conventional HBV-PCR assays, i.e. <116 IU / ml).
    • 18-70 yrs
    • Willingness and ability to give informed consent and to follow study procedures
    • willingness to use adequate contraception
    E.4Principal exclusion criteria
    • HBe antigen positive Hepatitis B
    • Co-infection with HCV, HDV or HIV – as based on positive serology or PCR

    • Preexisting polyneuropathy
    E.5 End points
    E.5.1Primary end point(s)

    E.5.1.1Timepoint(s) of evaluation of this end point
    After 48 weeks.
    E.5.2Secondary end point(s)
    1. Decline of quantitative HBs antigen at week 12 and 24
    2. Rate of patients with at least 10% HBs antigen loss at week 24 compared to baseline
    3.HBsAg seroconversion defined as percentage of subjects who become HBsAg negative and anti-HBs positive during the observation period
    4.Safety and tolerability of pegylated interferon alfa-2a when added to a continuing treatment with tenofovir, entecavir, lamivudine, adefovir, or a combination of those: Analysis of adverse events and laboratory data.

For patients with HBe seroconversion a continuation of nucleos(t)ides for at least 6 months is recommended. HBeAg negative patients without HBs-seroconversion will continue therapy with nucleos(t)ides as previously.
