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   43801   clinical trials with a EudraCT protocol, of which   7272   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.2 Objective of the trial
    E.2.1Main objective of the trial
    - To assess the long-term safety and tolerability of soticlestat when administered as adjunctive therapy to SOC (eg, ASMs, vagus nerve stimulation, ketogenic diet, modified Atkins diet) in subjects with DS or LGS.
    E.2.2Secondary objectives of the trial
    - To assess the effect of soticlestat on seizure frequency (convulsive seizures for the DS cohort, MMD seizures for the LGS cohort, and total seizure count for each cohort).
    - To assess the effect of soticlestat on the Clinical Global Impression of Improvement (CGI-I) (clinician) and Caregiver Global Impression of Improvement (Care GI-I).
    - To assess the effect of soticlestat on CGI-I Seizure Intensity and Duration.
    - To assess the effect of soticlestat on the CGI-I Nonseizure Symptoms completed by clinician with input from the caregiver.
    - To assess the effect on Quality of Life Inventory-Disability (QI-Disability).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Been previously enrolled in a phase 3 soticlestat clinical study.
    E.4Principal exclusion criteria
    Subjects will be excluded from study enrollment if they meet any of the following criteria:
    1. Unstable, clinically significant neurologic (other than the disease being studied), psychiatric, cardiovascular, ophthalmologic, pulmonary, hepatic, renal, metabolic, gastrointestinal, urologic, immunologic, hematopoietic, endocrine disease, malignancy including progressive tumors, or other abnormality that may impact the ability to participate in the study or that may potentially confound the study results. It is the responsibility of the investigator to assess the clinical significance; however, consultation with the medical monitor may be warranted.
    2. Abnormal and clinically significant ECG abnormality at Visit 1 including QT interval with Fridericia correction method (QTcF) >450 ms confirmed with a repeat ECG using manual measurement of QTcF. Clinically significant ECG abnormalities should be discussed with the medical monitor.
    3. Subject is currently pregnant or breastfeeding or is planning to become pregnant during the study or within 30 days of the last dose of study drug.
    4. Subject is considered by the investigator to be at imminent risk of suicide or injury to self, others, or property. Subjects who have positive answers on item numbers 4 or 5 on the C SSRS before dosing are excluded. This scale will only be administered to subjects aged ≥6 years.
