Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42752   clinical trials with a EudraCT protocol, of which   7042   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To assess the efficacy of intracranial delivery of AAVrh.10SGSH gene therapy (LYS-SAF302) in improving or stabilizing the neurodevelopmental status of MPS IIIA patients after 24 months (main cohort), compared to the expected evolution based on natural history data.
    E.2.2Secondary objectives of the trial
    To assess the safety and tolerability of intracranial delivery of LYS-SAF302 and to assess the treatment efficacy on the behavioral, sleep disturbances of the patients and on quality of life for both patient and parents.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    11. Documented MPS IIIA diagnosis based on genotyping confirming the SGSH gene mutations
    2. Age ≥ 30 months at screening (main cohort) or ≥6 months and < 30 months (ancillary cohort)
    3. Cognitive DQ score on BSID-III ≥ 50%
    4. Signed written informed consent before any study related procedure is performed
    5. Medical status sufficiently stable, in the opinion of the investigator, to adhere to the study visit schedule and other protocol requirements
    6. Confirmation by the study neurosurgeon and anesthesiologist of the feasibility of the neurosurgical procedure.
    E.4Principal exclusion criteria
    1. Homozygous for the S298P mutation or non-severe form of MPS IIIA, based on investigator’s judgement
    2. Participation in another gene or cell therapy clinical trial
    3. Past use of SGSH enzyme replacement therapy for a period exceeding 3 months. A washout period of at least 2 months is required prior to screening
    4. Current participation in a clinical trial of another investigational medicinal product.
    NOTE: Nutritional supplements, including Genistein at low dose (<150mg/Kg/day) are permitted if they are taken outside the context of an investigational trial
    5. History of bleeding disorder or current use of medications that, in the opinion of the investigator, place them at risk of bleeding following surgery
    6. Any condition that would contraindicate treatment with immunosuppressants such as
    tacrolimus, mycophenolate mofetil or steroids
    7. Rare and unrelated serious comorbidities e.g. Down syndrome, intraventricular hemorrhage in the new-born period, or extreme low birth weight (<1500 grams)
    8. History of poorly controlled seizure disorder
    9. Any vaccination 1 month prior to the planned surgery
    10. Visual or hearing impairment sufficient, in the clinical judgment of the investigator, to preclude cooperation with neurodevelopmental testing. Use of hearing aids is permitted.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy measurement is the comparison between the observed (post-surgery) evolution of cognitive development quotient (DQ) expressed by the ratio (DQ24/DQ0) between baseline and 24 months and the expected ratio calculated by applying a regression coefficient based on data from natural history studies.
    Cognitive DQ will be assessed by neurocognitive testing using the Bayley Scale for Infant and Toddler Development, 3rd Edition (BSID-III) or the Kauffman Assessment Battery for Children , 2nd Edition (KABC-II), depending on child’s age and ability. Primary and secondary analyses will be performed separately on the main and the ancillary cohorts.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Primary endpoint between baseline and 24 months.
    E.5.2Secondary end point(s)
    - The change from baseline in the cognitive development age (DA) and cognitive
    development quotient (DQ) assessed by neurocognitive tests (BSID III or KABCII)
    at all timepoints
    - The change from baseline in other DA and DQ (language and motor) assessed byneurocognitive tests (BSID III or KABC-II) at all timepoints
    -The percentage of patients with stabilized development age (DA) at 12 months and 24 months
    - The change from baseline in the total adaptive behavior composite standard score as measured by the Vineland Adaptive Behavior Scales (VABS-II) at 12 months and 24 months and change from baseline in total behavior problem as measured
    by the Child Behavior Checklist (CBCL) at 12 and 24 months
    - The change in sleep pattern as measured by the Children Sleep Habits Questionnaire (CSHQ) at 12 months and 24 months
    - The change from baseline in the patient/parent quality of life
    - The change from baseline in total cortical grey matter volume and white matter volume on MRI at 12 months and 24 months
    - The change from baseline in relevant disease biomarkers in CSF and PBMC
    E.5.2.1Timepoint(s) of evaluation of this end point
    BSID III, KABC-II and biomarkers will be assessed at all timepoints

    DA, VABS-II, CBCL, CSHQ, ITQOL-SF47, GHQ, HUI-3, PSI-4-SFMRI at 12 and 24 months for the main cohort. Corresponding timepoint of primary interest for the young cohort will be when all patients from the young cohort have reached 4 years of age.
