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   44237   clinical trials with a EudraCT protocol, of which   7338   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.

    A.3Full title of the trial
    An Open-Label, Multicenter Study with an Extension Phase to Evaluate the Safety, Tolerability, and Exposure-Efficacy Relationship of Perampanel Oral Suspension when Administered as an Adjunctive Therapy in Pediatric Subjects (Age 4 to less than 12 years) with Inadequately Controlled Partial-Onset Seizures or Primary Generalized Tonic-Clonic Seizures
    A.3.1Title of the trial for lay people, in easily understood, i.e. non-technical, language
    The study being done to see if the Study Drug is safe, tolerable, and can help control seizure in children with epilepsy who are aged 4 to less than 12 years of age and who are already taking seizure medications. The study will also look at pharmacokinetics, which is used to find out the concentration of perampanel in your child’s blood over a period of time.

    5. Have an unstable psychiatric diagnosis that may confound subjects’ ability to participate the study or that may prevent completion of the protocol specified tests (significant suicide risk, including suicidal behavior & ideation within 6 months before Visit 1, current psychotic disorder, acute mania).
    6. Any suicidal ideation with intent with or without a plan within 6 months before Visit 2 (ie answering “Yes” to questions 4 or 5 on the Suicidal Ideation section of the C-SSRS) in subjects aged > 6 years.
    7. Are scheduled and/or confirmed to have epilepsy surgery within 6 months after Visit 1; however, those who have previously documented “failed” epilepsy surgery will be allowed.
    8. Evidence of clinically significant disease (cardiac, respiratory, gastrointestinal, renal disease) that in the opinion of the investigators could affect the subject’s safety or interfere with the study assessments.
    9. Severe renal insufficiency

    12. Clinically significant ECG abnormality, including prolonged corrected QT interval defined as > 450 msec.
    13. Have a progressive central nervous system disease, including degenerative CNS diseases & progressive tumors.

    2. The relationship between plasma levels of perampanel and cognition endpoints including change from baselines in ABNAS, CBCL, and LGPT. In addition, depending on the AE data, the relationship between plasma levels of perampanel and select AEs will be assessed.
    3. Change from baseline at Week 23 and Week 52 in ABNAS, CBCL, and LGPT
    4. Changes from baseline at Week 23 and Week 52 in growth and development parameters (height, weight, thyroid, and IGF-1)
