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   43881   clinical trials with a EudraCT protocol, of which   7295   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Angelman syndrome is a neurogenetic disorder caused by a loss of function of the maternally inherited UBE3A gene (chromosome 15) which codes for UBE3A ubiquitin protein ligase. AS presents early in life severe developmental delays (motor, language and cognitive functioning, seizures and ataxia with happy demeanor and sociability). It is a non-degenerative, life-long disorder resulting in complete dependence on a caregiver that generally remains clinically unchanged with a normal life expectancy.
    E.1.1.1Medical condition in easily understood language
    Angelman syndrome is a genetic disorder that mainly affects the nervous system. Symptoms include severe intellectual disability and developmental disability with normal life expectancy.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the safety and tolerability of single and multiple dose-levels of multiple intrathecal bolus (ITB) administrations of ION582 in patients with Angelman syndrome (AS) based on incidence and severity of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), changes in vital signs, and changes in clinical laboratory parameters.
    E.2.2Secondary objectives of the trial
    Secondary Objective
    Characterize the pharmacokinetics (PK) in cerebrospinal fluid (CSF), plasma and urine of ascending dose-levels of multiple IT bolus administrations of ION582 in patients with AS.

    Exploratory Objective
    To evaluate the effects of ION582 on AS biomarkers and clinical features including motor, language, cognitive functioning, sleep, and electroencephalogram (EEG) patterns in patients with AS.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Patient has a documented and certified diagnosis of Angelman Syndrome (AS) (ubiquitin-protein ligase E3A [UBE3A] deletion or UBE3A mutation) provided by the Investigator.
    2. Male or female between the ages of 2-50 years of age, with signed informed consent from parent(s) or legal guardian(s).
    3. Currently receiving stable standard of care treatments, such as stable doses of anti-epileptic medication, behavioral management medications, sleep medications, gabapentin, cannabidiol, and including special diets, supplements or nutritional support for at least 3 months prior to first dose.
    4. Follow good study practice and not participate in sharing of personal or study information on social media platforms, such as any website or social media (e.g., Facebook, Instagram, Twitter, YouTube, etc.) until notified that the study is completed.
    E.4Principal exclusion criteria
    1. Has documented molecular AS confirmation of paternal uniparental disomy (UPD) or imprinting defect (ID).
    2. Any clinically significant (CS) cardiovascular, endocrine, hepatic, renal, pulmonary, gastrointestinal, neurologic, malignant, metabolic, psychiatric condition, or other condition that, in the judgement of the Investigator, will pose a safety risk, will make the patient unsuitable for participation, and/or unable to complete the study procedures. Has poorly controlled seizures as determined by the Investigator or has documented Status Epilepticus in the past 6 months that could pose a safety risk while on the study.
    3. Known bone, spine, bleeding or other disorder that exposes the patient to risk of injury or unsuccessful lumbar puncture. Previous treatment with an oligonucleotide (including small interfering ribonucleic acid, ASOs). COVID-19 vaccinations are allowed.
    4. Any prior use of gene therapy. Have any other conditions, which, in the opinion of the investigator would make the participant unsuitable for inclusion or could interfere with the participant taking part in or completing the study.
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint will be the assessment of patient safety and tolerability of ION582 by determining the incidence and severity of the below parameters:
    • Incidence and severity of TEAEs and SAEs, as well as changes in concomitant medications
    • Physical examination and standard neurological assessment
    • Vital signs (body temperature, heart rate [HR], blood pressure [BP], weight)
    • Electrocardiograms (ECGs)
    • CSF safety labs (cell counts, protein, glucose)
    • Laboratory tests (clinical chemistry, hematology, urinalysis)
    E.5.1.1Timepoint(s) of evaluation of this end point
    throughout the study
    E.5.2Secondary end point(s)
    Secondary Endpoints
    Pharmacokinetic parameters of ION582 will be evaluated through the collection of CSF, plasma and urine samples.
    ION582 concentration in CSF will be summarized.
    Plasma maximum concentration (Cmax), area under the curve (AUC), elimination half-life and trough and post-distribution ION582 levels will be assessed, where appropriate and possible.
    Amount of ION582 excreted in urine, percent of dose excreted, and renal clearance (if possible) following first dose will be summarized, as appropriate.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Secondary Endpoints
    For the Part 1:
    CSF and plasma samples will be collected pre-dose on each dosing day (day 1, 29 and 85) for PK analyses.
    Additional plasma samples will be collected on Study Day 1 (1, 3, and 6 hours post-ITB injection), Study Day 2 (24 hours post-ITB injection), and Study Days 113, 169, and 309 (any 1 time point during the visit). Urine will be collected for 24 hours on Day 1 starting at the time of dosing, only for patients in Cohorts D and E and if they are able.

    For the Part 2:
    CSF and plasma samples will be collected pre-dose on each dosing day (days 1 ,85, 169, 253 and 337)) for PK analyses.
    Additional plasma samples will be collected on Study Day 1 ( 3 and 6 hours post-ITB injection), and at 3 mo and 8 mo visits (any 1 time point during the visit).
