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   42564   clinical trials with a EudraCT protocol, of which   7007   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 determine the safety and tolerability of rhHNS via ascending doses administered via a surgically implanted intrathecal drug delivery device (IDDD) once monthly or every other week (EOW) for 6 months, in patients with MPS IIIA.
    E.2.2Secondary objectives of the trial
    •To determine by dose group the effects of IT administration of rhHNS, as measured as (1) change from baseline values, and (2) comparison to values obtained in a longitudinal, 12 month, natural history study of untreated patients with MPS IIIA in the Shire HGT SAN 053 Surrogate Endpoint Trial, on the following measurements/assessments over a 6 month period:
    •Standardized neurocognitive and behavioral assessments
    •Concentration of rhHNS in cerebrospinal fluid (CSF) and serum.
    •Concentration of safety/potential surrogate efficacy biomarkers in CSF, urine, and serum.
    •Concentration of heparan sulfate and heparan sulfate derivatives in urine and CSF
    •Brain MRI and auditory brainstem response
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. a.)Patients have a documented deficiency in sulfamidase enzyme activity of ≤10% of the lower limit of the normal range as measured in fibroblasts or leukocytes (based on measurements by a laboratory that is acceptable to Shire HGT).
    AND EITHER b or C
    b.)Patients have a normal enzyme activity level of at least 1 other sulfatase (to rule out multiple sulfatase deficiency) as measured in fibroblasts or leukocytes (based on measurements by a laboratory that is acceptable to Shire HGT).
    c.) Patients have 2 documented mutations (based on assessments by a laboratory that is acceptable to Shire HGT).
    2. The patient is ≥3 years of age and has a developmental age above 1 year (developmental age will be determined by the screening neurocognitive and developmental tests).
    3. Patients must be medically stable, in the opinion of the Investigator, to accommodate the protocol requirements, including travel, assessments, and IDDD surgery, without placing an undue burden on the patient/patient's family.
    4. The patient’s parent(s) or legal guardian must have voluntarily signed an Institutional Review Board/Independent Ethics Committee-approved informed consent form
    E.4Principal exclusion criteria
    1. The patient has significant non-MPS IIIA related central nervous system (CNS) impairment or behavioral disturbances that would confound the scientific integrity or interpretation of study assessments, as determined by the Investigator.
    2. The patient has MPS IIIA behavioral-related issues, as determined by the Investigator that would preclude performance of study neurocognitive and developmental testing procedures.
    3. The patient is pregnant, breast feeding, or is a female patient of childbearing potential who will not or cannot comply with the use of an acceptable method of birth control
    4. The patient is blind and/or deaf
    5. The patient has any known or suspected hypersensitivity to anesthesia or is thought to have an unacceptably high risk for anesthesia due to airway compromise or other conditions.
    6. The patient or the patient's family has a history of neuroleptic malignant syndrome, malignant hyperthermia, or other anesthesia-related concerns.
    7. The Investigator may choose to exclude patients who have had complications resulting from prior lumbar punctures.
    8. The patient has a CNS shunt.
    9. The patient has skeletomuscular/spinal abnormalities or other contraindications for the surgical implantation of the IDDD.
    10. The patient has a history of poorly controlled seizure disorder.
    11. The patient is currently receiving psychotropic or other medications, which in the Investigator’s opinion, would be likely to substantially confound test results and the dose and regimen of which cannot be kept constant throughout the study.
    12. The patient cannot sustain absence from aspirin, non-steroidal medications, or medications that affect blood clotting within 1 week prior to a relevant study-related procedure (eg, device implantation if applicable), or has ingested such medications within 1 week before any procedures in which any change in clotting activity would be deleterious.
    13. The patient has received treatment with any investigational drug or a device intended as a treatment for MPS IIIA within the 30 days prior to, or during the study, or is currently enrolled in another study that involves an investigational drug or device (screening through safety follow-up contact).
    14. The patient has received a hematopoietic stem cell or bone marrow transplant.
    15. The patient’s parent(s), or patient’s legal guardian(s) is/are unable to provide consent or the patient cannot provide assent,
