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   43857   clinical trials with a EudraCT protocol, of which   7284   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 ).

    General information about the trial
    Main objective of the trial
    The primary objective of this study is to evaluate the efficacy of LEV used as monotherapy, with efficacy measured as 6-month seizure freedom at the last evaluated dose in the LEV 1000 mg/day to 2000 mg/day group, in newly or recently diagnosed epilepsy subjects.
    Protection of trial subjects
    N01375 was continued until the Ministry of Health, Labor and Welfare (Japan) approved the use of Levetiracetam (LEV) monotherapy for Partial Onset Seizures (POS) in adults and until all subjects who were taking LEV as investigational medicinal product (IMP) had a the option to switch to commercial LEV in Japan. Antidepressant use was allowed if the medication and dose were stable for at least 6 months prior to Visit 1 and the medication and dose were to be kept stable for the entire study duration. The following medications were used as rescue medications at the investigator’s discretion to maintain the subject’s safety: - Diazepam (suppository, injection) - Phenobarbital sodium (suppository, injection) - Chloral hydrate (enema preparation, suppository) - Phenytoin sodium (injection) - Fosphenytoin sodium hydrate (injection)
    Background therapy
    Not applicable
    Evidence for comparator
    Based on the controlled studies that evaluated Anti-Epileptic Drugs (AEDs) in the past, the magnitude of the clinical effects of conventional AEDs as the percentage of subjects who achieved 6-month seizure freedom was expected to be approximately 50 % in subjects with newly or recently diagnosed Partial Onset Seizures (POS).The ILAE Treatment Guidelines (Glauser, 2006) stated that non-inferiority outcomes with any relative difference >20 % in the efficacy evaluation had to be regarded as clinically important. According to this, a threshold level of 40 % (50 % − 0.2 × 50 %) in efficacy of Levetiracetam (LEV) monotherapy was defined for the percentage of the subjects who would achieve seizure freedom for 6 months by detecting the statistically significant difference between the defined threshold level and the study result to be obtained. The primary efficacy evaluation was to be performed on the LEV 1000 mg/day to 2000 mg/day groups.
