Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   39211   clinical trials with a EudraCT protocol, of which   6426   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Recruitment
    Recruitment details
    This study was a dose extension study of pediatric subjects with refractory partial-onset seizures who had completed study A0081074 (NCT00437281, Eudra CT number 2010-020730-26). Subjects were enrolled in 3 countries at 13 study centers with 13 investigators: Republic of Korea (1 center), Mexico (1 center), and the United States (11 centers).

    Pre-assignment
    Screening details
    Each subject was restricted to the dose levels that they had previously tolerated, or that had shown acceptable safety and tolerability in study A0081074 (NCT00437281, Eudra CT number 2010-020730-26) for the subject's age group.

    Number of Subjects With Adverse Events (AE) [1]
    End point description
    An AE is any untoward medical occurrence in a clinical investigation subject administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage. A serious adverse event (SAE) is any untoward medical occurrence at any dose that: results in death; is life-threatening (immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in congenital anomaly/birth defect. Safety analysis set: All subjects who received at least one dose of study medication were included.

Examination of abdomen, breasts, ears, extremities, eyes, genitourinary, head, heart, lungs, lymph nodes, mouth, musculoskeletal, neck, nose, ocular fundi, skin, throat, thyroid and general examinations were done. Evaluation was done based on presence of abnormality which were noted as "abnormal" and no abnormalities in the sites were reported as "normal".

    Twenty-eight-day seizure frequencies were to be calculated from the seizure diaries and were to be reviewed. However, due to the nature of the data collection and due to inability to clearly differentiate no seizures versus seizures, accurate computation of this data was not performed. Hence, the seizure data was reported as AE. Safety analysis set: All subjects who received at least one dose of study medication were included. Here "99999" in the seizure frequency signifies not available (NA). Due to the nature of the data collection and due to inability to clearly differentiate no seizures versus seizures, accurate computation of this data was not performed.
