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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    • Describe the pharmacokinetics (PK) and pharmacodynamics (PD) of eculizumab in relapsing pediatric patients with NMOSD.
    Extension Treatment Period:
    • Characterize long-term safety of eculizumab treatment in pediatric patients with NMOSD.
    • Characterize long-term efficacy of eculizumab treatment in pediatric patients with NMOSD.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Male or female patients aged 2 years to < 18 years at time of assent/consent.

    • Expanded Disability Status Scale score ≤ 7
    • Patients who enter the study receiving supportive immunosuppressive therapies for the prevention of relapse, either in combination or monotherapy, must be on a stable dosing regimen of adequate duration prior to Screening and remain on a stable dosing regimen during the
    Screening Period.
    • Vaccinated against N meningitidis within 3 years prior to, or at the time of initiating eculizumab. Patients who initiate study drug treatment less than 2 weeks after receiving a meningococcal vaccine must receive appropriate prophylactic antibiotics until 2 weeks after the vaccination.
    • Documented vaccination against Hib and S pneumoniae infections 2 weeks prior to dosing as per local and country-specific immunization guidelines for the appropriate age group.
    • Willing and capable to give informed assent (if applicable, as determined by the central Institutional Review Boards (IRBs)/Independent Ethics Committees (IECs) and in accordance with local requirements) and whose parent/legal guardian are willing and able to give written informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.
    E.4Principal exclusion criteria
    • Patients known to be human immunodeficiency virus (HIV) positive or with congenital immunodeficiency.
    • Unresolved meningococcal or other serious infection.

    • Use of immunomodulatory therapies for multiple sclerosis within 3 months prior to Screening.
    • Patient is currently treated with a biologic medication that may affect immune system functioning, or has stopped treatment with a biologic medication that may affect immune system functioning, and 5 half-lives of the medication have not elapsed by the time of the Screening Visit, unless otherwise specified in the protocol.
    E.5 End points
    E.5.1Primary end point(s)
    • Change from Baseline in the Annualized Relapse Rate (ARR).
    • Time to First Relapse (TFR).
    E.5.1.1Timepoint(s) of evaluation of this end point
    Primary Treatment Period:
    throughout the primary treatment period
    and
    52/53* Weeks
    * For patients who start in weight cohort 10 to <20 kg, the one-year evaluation will occur on Week 53, an odd-numbered week, because maintenance dosing, which is administered every 2 weeks, begins on Week 1. For all other cohorts the one-year evaluation will occur on Week 52, because maintenance dosing begins on an even-numbered week. Hence, the end of the Primary Treatment Period is designated as Week 52/53 throughout the study protocol.
    E.5.2Secondary end point(s)
    Primary Treatment Period:

    Safety:
    • Incidence of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and adverse events leading to study drug discontinuation.
    • Incidence of antidrug antibodies (ADA).
    • Changes from Baseline in vital signs, electrocardiogram (ECG) parameters, and clinical laboratory assessments.
    • Change from Baseline in both weight and height.

    Efficacy:
    Disease-related disability:
    • Change from Baseline in Expanded Disability Status Scale (EDSS) score in patients ≥5 years of age.
    • Change from Baseline in the Hauser Ambulatory Index (HAI) score.
    Quality of life:
    • Change from Baseline in Pediatric Quality of Life Inventory (PedsQL) in patients ≥5 years of age.
    • Change from Baseline in Pediatric Quality of Life Inventory Parent Proxy (PedsQL Parent Proxy) in patients < 5 years of age.
    Change in ophthalmologic examination findings:
    • Change from Baseline in Visual Acuity (VA) as measured by the Snellen or LEA symbols Eye Chart examination in all patients.
    • Change from Baseline in Confrontational Visual Fields (VF) as measured during ophthalmologic examination in all patients.
    • Change from Baseline in color vision as measured during ophthalmologic examination in all patients.

    PK/PD:
    • Changes in serum eculizumab concentration over time.
    • Changes in serum free complement protein 5 (C5) concentrations and in vitro hemolytic activity over time.

    Extension Treatment Period:
    The safety and efficacy endpoints of the Primary Treatment Period will be evaluated during the Extension Treatment Period.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Primary Treatment Period:
    throughout the primary treatment period
    At 52/53* weeks
    * For patients who start in weight cohort 10 to <20 kg, the one-year evaluation will occur on Week 53, an odd-numbered week, because maintenance dosing, which is administered every 2 weeks, begins on Week 1. For all other cohorts the one-year evaluation will occur on Week 52, because maintenance dosing begins on an even-numbered week. Hence, the end of the Primary Treatment Period is designated as Week 52/53 throughout the study protocol.
