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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    codon-optimized human coagulation hFIX gene, to adult subjects with
    severe or moderately severe haemophilia B.
    E.2.2Secondary objectives of the trial
    To assess the long-term efficacy of a systemic administration of AAV5-hFIX, an adeno-associated viral (AAV) vector containing a codon-optimized human coagulation Factor IX (hFIX) gene, to adult subjects with severe or moderately severe haemophilia B.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is to demonstrate the long-term safety (6-10 years) after dosing of AAV5-hFIX.

    Primary safety endpoints include the following:
    - AEs possibly or probably related to previous AAV5-hFIX administration
    - Neutralizing FIX antibodies (FIX inhibitors)
    - ALT aspartate aminotransferase (AST) levels
    - Liver pathology (assessed by ultrasound)
    - Alpha-fetoprotein (AFP)
    E.5.1.1Timepoint(s) of evaluation of this end point
    The individual subjects will be followed for an additional five years, 6-10 years after dosing of AAV5-hFIX.
    The occurrence of adverse events (AEs) related to previous AAV5-hFIX administration in patients will be continuously monitored.
    ALT/AST will be measured every 6 months
    Abdominal ultrasounds will occur at all clinic visits
    Alpha-fetoprotein (AFP) and Anti-AAV5 antibodies will be measured every 12 months
    E.5.2Secondary end point(s)
    The secondary endpoints will focus on the long-term efficacy (6-10 years) after dosing of AAV5-hFIX on FIX activity, overall FIX utilization, bleeding events, any procedures, and QoL.

    Secondary efficacy endpoints include the following:
    - Endogenous FIX activity
    - Utilization of FIX-replacement therapy
    - Annualized bleeding rate; including the following:
    o All bleeds (treated and untreated)
    o Spontaneous bleeds
    o Traumatic bleeds
    o Joint bleeds
    - Procedures (including major and minor surgeries)
    - SF-36 and EQ-5D-5L Quality of Life (QoL) scores
    - HJHS
    E.5.2.1Timepoint(s) of evaluation of this end point
    Endogenous FIX activity, Utilization of FIX-replacement therapy, FIX inhibitors and bleeding rates and procedures will be measured every 6 months

    QoL and HJHS will be measured every 12 months
