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   44313   clinical trials with a EudraCT protocol, of which   7357   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Chronic Granulomatous Disease (CGD) is a rare inherited disorder (1/250,000) of the phagocytes characterized by the inability of phagocytes (monocytes and neutrophils) to produce reactive oxygen species (ROS) in response to a stimulus, due to the absence of NADPH oxidase activity. Affected patients present an elevated susceptibility to bacterial and fungal infections, as well as an excessive inflammatory response that leads to granuloma formation.
    E.1.1.1Medical condition in easily understood language
    Chronic Granulomatous Disease (CGD) is a genetic disorder that affects boys. It is caused by errors in a gene that makes part of the immune system.
    E.1.1.2Therapeutic area Diseases [C] - Immune System Diseases [C20]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The purpose of this phase I/II clinical trial is to assess the safety and the possible efficacy (by biochemical and functional reconstitution in progeny of engrafted cells and stability at 12 months) of autologous CD34+ cells transduced with the G1XCGD lentiviral vector, containing the human gp91phox (CYBB) gene, injected intravenously in patients adults or minors suffering from X-Linked Chronic Granulomatous Disease.
    E.2.2Secondary objectives of the trial
    -Clinical efficacy and longitudinal evaluation of clinical effect in terms of improved immunity against bacterial and fungal infection
    -Transduction of CD34+ haematopoietic stem cells from X-CGD patients by ex vivo lentivirus-mediated gene transfer
    -Evaluation of engraftment kinetics and stability
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    -Male X-CGD patients >23 months of age. Youngest patients (>1 month and ≤ 23 months) may be enrolled at physician’s appreciation
    -Molecular diagnosis confirmed by DNA sequencing and supported by laboratory evidence for absent or reduction > 70% of the biochemical activity of the NAHPD-oxidase
    -At least one ongoing or resistant or at high risk of relapse severe infection and/or inflammatory complications requiring hospitalisation despite conventional therapy
    -No HLA-matched donor available after 3 months search, unless the risk of waiting for a potential match or for performing an allogeneic transplant is considered unacceptable
    -No co-infection with Human Immunodeficiency Virus (HIV) or hepatitis B virus (HBs Ag positive) or hepatitis C virus (HCV RNA positive)
    -Written informed consent for adult patient
    -Parental/guardian and where appropriate child’s signed consent/assent
    E.4Principal exclusion criteria
    -10/10 HLA identical (A, B, C, DR, DQ) family or unrelated or cord blood donor unless there is deemed to be an unacceptable risk associated with an allogeneic procedure
    -Contraindication for leukapheresis (anaemia Hb <8g/dl, cardiovascular instability, severe coagulopathy)
    -Contraindication for administration of conditioning medication and any component of the Investigational Medicinal Product (IMP) preparation
    -Administration of gamma interferon within 30 days before the infusion of transduced autologous CD34+ cells
    -Participation in another experimental therapeutic protocol within 6 months prior to baseline and during the study period
    -Any other condition that, in the opinion of the Investigator, may compromise the safety or compliance of the patient or would preclude the patient from successful completion of the study
    -Patient/Parent/Guardian unable or unwilling to comply with the protocol requirements
    E.5 End points
    E.5.1Primary end point(s)
    Safety as measured by the incidence of adverse events due either to the conditioning regimen or to the procedure itself.
    Efficacy as measured by the restoration and stability over time of the NADPH functioning granulocytes assessed by a DHR test (≥ 5% of expressing cells at 12 months).
    E.5.1.1Timepoint(s) of evaluation of this end point
    For safety end point: throughout the study
    For efficacy: at 12 months
    E.5.2Secondary end point(s)
    -Normalisation of nutritional status, growth, development (as measured by clinical evaluation), clearing of the pre-existing severe infection and/or chronic inflammatory lesions which recommended patient’s inclusion
    -Percentage of transduced CD34+ haematopoietic stem cell at one year and percentage of transduced mature blood cells over time (at month 1, 2,3, 6, 9, 12, 18 and 24 months)
    -Immunological reconstitution as measured by evidence of restored neutrophil functionality and immunity against bacterial and fungal infections over time.
    E.5.2.1Timepoint(s) of evaluation of this end point
    at month 1, 2,3, 6, 9, 12, 18 and 24 months
