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   43974   clinical trials with a EudraCT protocol, of which   7312   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
    To evaluate the feasibility of WT1-targeted DC vaccine production and administration in pediatric patients with HGG and DIPG, either in combination with first-line chemoradiation treatment or as adjuvant therapy following previous therapies, and to investigate the resulting safety profile.
    E.2.2Secondary objectives of the trial
    - To assess indicators of clinical activity of vaccination with WT1-targeted DC in pediatric patients with HGG and DIPG
    - To determine the in vivo immunogenicity of WT1-targeted DC vaccinations in pediatric patients with HGG and DIPG
    - To document and characterize changes in patient- and proxy-reported general and disease-specific quality of life
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    - Diagnosis of HGG (WHO grade III or IV, histologically verified) or DIPG (verified by radiologic criteria (magnetic resonance imaging (MRI)) or by histology. A biopsy is not required but recommended.)
    - Aged ≥ 12 months and < 18 years at the time of signing the informed consent
    - Body weight ≥ 10 kg
    - Lansky score (for patients < 16 years) or Karnofsky score (for patients ≥ 16 years) of ≥ 50
    - Reasonable life expectancy ≥ 8 weeks, as estimated by the treating physician
    - Adequate hematological blood values and sufficient recovery from treatment-related toxicities (> grade 1) following previous anti-glioma treatments, as judged by the treating physician (applies to stratum B only).
    - Written informed consent of parents or legal guardian and of patients aged 12 years or older. Written informed consent of patients younger than 12 years is optional.
    - Willing and able to comply with the protocol, as judged by the treating physician
    - Female patients of child bearing potential must have a negative serum or urine pregnancy test at the time of screening. Female patients of child bearing potential and male patients must agree to use effective contraception before, during and for at least hundred days after the last study treatment administration. Female subjects who are breastfeeding should discontinue nursing prior to the first dose of study treatment and until at least hundred days after the last study treatment administration.
    E.4Principal exclusion criteria
    - Use of any investigational agents ≤ 4 weeks before the planned day of leukapheresis.
    - Concomitant malignancy or history of another malignancy (unless the Investigator rationalizes otherwise)
    - Known concomitant presence of any active immunosuppressive disease (e.g. HIV) or any active autoimmune condition, except for vitiligo
    - Any pre-existing contra-indication for contrast-enhanced MRI
    - Pregnant or breastfeeding
    - Any other condition, either physical or psychological, or reasonable suspicion thereof on clinical or special investigation, which contraindicates the use of the vaccine, or may negatively affect patient compliance, or may place the patient at higher risk of potential treatment complications
    E.5 End points
    E.5.1Primary end point(s)
    (i) Feasibility
    - Proportion of patients in the intention-to-treat (ITT) population that had successful leukapheresis
    - Proportion of patients in the ITT population that had successful vaccine production (i.e. production of 9 or more vaccines meeting quality control requirements)
    - Proportion of patients in the ITT population who complete the study treatment schedule (i.e. from leukapheresis until administration of the 9th vaccine)
    - Proportion of efficacy evaluable patients in the ITT population

    (ii) Safety
    Occurrence of AEs and SAEs during DC vaccine administration and follow-up period:
    - Proportion of patients of the safety population that experienced (S)AEs possibly, probably or definitely related to DC vaccination
    - Number and grade of (S)AEs in the safety population

    E.5.1.1Timepoint(s) of evaluation of this end point
    At end of study (i.e. when all patients have reached 90 days after final DC vaccine administration or 24 months after study entry (whichever occurs later)) data for feasibility and safety will be evaluated.
    E.5.2Secondary end point(s)
    (i) Indicators of clinical activity:
    - Best overall response
    - Progression free survival
    - Overall survival

    (ii) Immunogenicity
    The immunogenicity endpoints include, but are not limited to, the following measures of (anti-tumor) immune responses:
    - Functional WT1-specific T cell responses
    - Occurrence of WT1-specific CD8+ T cells
    - Functional WT1-specific T cell responses

    (iii) Quality of life
    - How patients experience different phases of the study treatment schedule
    - How patient- and proxy-reported disease-related symptoms evolve over time during the study
    - How patient- and proxy-reported general quality of life evolves over time during the study
    E.5.2.1Timepoint(s) of evaluation of this end point
    At end of study (i.e. when all patients have reached 90 days after final DC vaccine administration or 24 months after study entry (whichever occurs later)) data for clinical activity, immunogenicity and quality of life questionnaires will be evaluated.
