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   43845   clinical trials with a EudraCT protocol, of which   7282   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.1.2System Organ Class 10010331 - Congenital, familial and genetic disorders
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    •To monitor and evaluate the long-term safety and tolerability of EDS-EP in AT patients.
    •To evaluate the long term effect of EDS-EP in treating CNS symptoms as measured by the “Modified” International Cooperative Ataxia Rating Scale (mICARS), and Clinical Global Impression of severity and change (CGI-S/C)
    E.2.2Secondary objectives of the trial
    To evaluate the long-term effect of EDS-EP on health related Quality of Life (QoL; EQ-5D-5L scale).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1.Patient completed the double-blind period in the IEDAT-02-2015 trial and must have completed the final (Visit 15/Month 12) efficacy assessments of IEDAT-02-2015.
    2.Patient tolerated the study medication, without any evidence of steroid adverse events, or treatment-related severe/ serious adverse events.
    3.Body weight > 15 kg.
    4.The patient and his/her parent/caregiver (if below the age of consent), or a legal representative, has provided written informed consent to participate. If consent is provided solely by the caregiver in accordance with local regulations, the patient must provide assent to participate in the study.
    5.Patient does not present safety contraindications for continuation of treatment, as determined by the Principal Investigator (PI) according to the procedures described below.

    Procedure for selecting patients for further treatment:
    The Principal Investigator will ask all patients who meet the above requirements, and determine their interest in continuing to receive treatment with the study medication in a new protocol. The Principal Investigator will then determine the eligibility of the patients on the basis of his/her clinical judgement of patients’ status and their safety.

    E.4Principal exclusion criteria
    Females that are
    a. pregnant, or are breast-feeding (for EU countries only);
    b. of childbearing potential, pregnant, or are breast-feeding (for US and Rest of World countries).
    Females of childbearing potential using adequate birth control will be eligible. A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. See Section 11.7 Concomitant Medications for adequate methods of birth control.
    2.A disability that may prevent the patient from completing all study requirements.
    3.Current participation in a clinical study with another investigational drug.
    Medical History and Current Status
    4.CD4+ lymphocytes count <400/mm3 (for patients 6 years of age) or <200/mm3 (for patients >6 years).
    5.Current neoplastic disease.
    6.Severe impairment of the immunological system.
    7.Severe or unstable pulmonary disease.
    8.Uncontrolled diabetes.
    Patients with diabetes that has been stabilized (i.e. no hypoglycemic or hyperglycemic episodes in the past 3 months) will be eligible.
    9.Any other severe, unstable, or serious disease or condition that in the Investigator’s opinion would put the patient at risk for imminent life-threatening morbidity, need for hospitalization, or mortality.
    10.Eligibility of patients with abnormal laboratory test values will be determined by the Investigator.
    11.Confirmed hemoglobinopathies, e.g. hemoglobin C disease, sickle cell anemia, or thalassemia.
    12.Moderate or severe renal and/or hepatic impairment.
    13.Patients who experienced moderate/ severe steroid side effects, or moderate/ severe adverse events associated with the study medication administered in the IEDAT-02 study.
    Prior/Concomitant Medication
    14.Requires treatment with an oral or parenteral steroid. Treatment with inhaled or intranasal steroids for asthma or allergies, as well as use of topical steroids will be permitted.
    15.Requires any other concomitant medication prohibited by the protocol.
    16.Use of any drug that is a strong inducer/inhibitor of CYP3A4.

    E.5.1Primary end point(s)
    To monitor and evaluate the long-term safety and tolerability of EDS-EP in AT patients
    E.5.1.1Timepoint(s) of evaluation of this end point
    During the study, long-term efficacy assessments will be performed every 6 months, while safety parameters will be assessed at each monthly visit.

    To evaluate the long-term effect of EDS-EP on health related Quality of Life (QoL; EQ-5D-5L scale).
    E.5.2.1Timepoint(s) of evaluation of this end point
    During the study, long-term efficacy assessments will be performed every 6 months, while safety parameters will be assessed at each monthly visit.
