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.

    General information about the trial
    Main objective of the trial
    The purpose of this study is to determine if ABI-H0731 given in combination with a standard of care (SOC) entecavir (ETV) is safe and effective in participants with chronic hepatitis B infection (cHBV).
    Protection of trial subjects
    This study will be conducted in compliance with IRB/IEC and International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines; Title 21 Part 56 of the US Code of Federal Regulations (CFR) relating to IRBs/IECs and GCP as described in the US FDA CFR (21 CFR § 50, 56, 312; applicable ICH guidelines regarding clinical safety data management (E2A, E2B(R3)); European Community directives 2001/20, 2001/83, 2003/94 and 2005/28 as enacted into local law, and with ICH guidelines regarding scientific integrity (E4, E8, E9, and E10). In addition, this study will adhere to all local regulatory requirements, and requirements for data protection.

    [6] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: Analysis was only planned for the ABI-H0731 arm.
    End point values
    ABI-H0731 + SOC ETV

    Notes
    [7] - Trough to peak ratios were not calculated due to an insufficient # of optional peak exposure samples
    No statistical analyses for this end point

    Reporting group title
    ABI-H0731 + SOC ETV
    Reporting group description
    Participants with chronic hepatitis B infection (cHBV) who are currently not being treated will receive ABI-H0731 along with standard of care (SOC) entecavir (ETV) tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to continue open-label ABI-H0731 for up to an additional year if necessary.

    Reporting group title
    Placebo + SOC ETV
    Reporting group description
    Participants with cHBV who are currently not being treated will receive matching placebo along with SOC ETV tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to start treatment on open-label ABI-H0731 for up to a year if necessary.
