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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to assess the long-term safety of FLT190 in subjects with Fabry disease.
    E.2.2Secondary objectives of the trial
    • To investigate the durability of endogenous production of αGLA enzyme.

    • To investigate the clearance of Gb3 and LysoGb3 in plasma and urine.

    • To investigate the clearance of cellular Gb3 inclusions in skin and renal biopsies.

    • To describe the immune responses to the αGLA transgene product.

    • To assess viral shedding in various body fluids, where applicable.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    (i) Subjects who have previously received FLT190 (including those who may have required recommencement/initiation of ERT/PCT).

    (ii) Subjects able to give full informed consent and able to comply with all requirements of the study including long-term follow-up for 60 months (5 years) post-treatment.
    E.4Principal exclusion criteria
    Subjects who do not meet the inclusion criteria will be excluded
    E.5 End points
    E.5.1Primary end point(s)
    • The primary safety endpoint will be assessed by the reporting of adverse event (AE) according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

    • Other safety endpoints will be reviewed including:
    - Laboratory parameter abnormalities
    - Vital signs, physical examination, liver ultrasound, and electrocardiogram (ECG) abnormalities
    E.5.1.1Timepoint(s) of evaluation of this end point
    Assessments will run throughout the study
    E.5.2Secondary end point(s)
    - Production of αGLA enzyme will be summarised over time and durability investigated. Change from baseline in plasma αGLA activity will be summarised and plotted for each subject and overall.

    - Change from baseline in Gb3 and LysoGb3 in plasma and urine will be summarised and plotted for each subject and overall.

    - Change from baseline in cellular Gb3 inclusions in skin and renal biopsies will be summarised and plotted. A detailed description of the variables that will be studied is provided in the Biopsy Analysis Plan.

    - Change from baseline in αGLA antibody levels will be summarised and plotted. Where applicable, descriptive statistics (number of observations, mean, standard deviation, minimum, median, and maximum values) will be calculated for other immune response laboratory tests at applicable visits.

    - Clearance of vector genomes in blood (plasma), saliva, urine, stool, and semen will be assessed, and levels summarised until no further shedding is seen in a minimum of three consecutive samples. This may occur in the preceding treatment study and, in this case, will not be followed-up further within this protocol. The time to clearance (from FLT190 administration until the third consecutive clear sample) will be summarised and may be plotted.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Assessments will run throughout the study.

    Clearance of vector genomes in blood (plasma), saliva, urine, stool, and semen will be assessed, and levels summarised until no further shedding is seen in a minimum of three consecutive samples.
