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   38462   clinical trials with a EudraCT protocol, of which   6315   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.

    General information about the trial
    Main objective of the trial
    The primary objective of the study was to assess the safety and tolerability of brivaracetam (BRV) at the dose range from 20 to 150 mg/day in twice daily administration in subjects suffering from localization-related or generalized epilepsy not fully controlled despite optimal treatment with 1 to 3 concomitant antiepileptic drug(s) (AED[s]), compared to placebo (PBO).

    End point description
    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    Partial (Type I) seizures can be classified into one of the following three groups: - Simple partial seizures - Complex partial seizures - Partial seizures evolving to generalized tonic-clonic convulsions. Partial Onset Seizure (POS) frequency per week over the Treatment Period (TP) was calculated as: (Total Type I seizures over the TP)*7/(Total number of days with no missing seizure count in the TP)

    The Quality of Life in Epilepsy Inventory-Form 31 (QOLIE-31-P) is an adaptation of the original QOLIE-31 instrument that includes 30 items grouped into 7 multi-item subscales: Seizure Worry (5 items), Overall Quality of Life (2 items), Emotional Well-being (5 items), Energy/Fatigue (4 items), Cognitive Functioning (6 items), Medication Effects (3 items) and Daily Activities/Social Functioning (5 items), and a Health Status item. In addition to the 31 items of the QOLIE-31, the QOLIE-31-P contains 7 items asking the subjects to rate the degree of 'distress' related to the topic of each subscale (ie, distress items). The QOLIE-31-P also contains an item asking about the relative importance of each subscale topic (ie, prioritization item). The subscale scores, the total score and the Health Status item score were calculated according to the scoring algorithm defined by the author with scores ranging from 0 to 100 and higher scores indicating better function.

The subscale scores, the total score and the Health Status item score were calculated according to the scoring algorithm defined by the author with scores ranging from 0 to 100 and higher scores indicating better function.

    The Hospital Anxiety and Depression Scale (HADS) was used to evaluate Anxiety and Depression. The HADS was developed as a self-administered scale to assess the presence and severity of Anxiety and Depression. It consists of 14 items that are scored on a 4-point severity scale ranging from 0 to 3. A score per dimension was calculated with each score ranging from 0 to 21 (higher scores indicating greater problems). A negative value in change from Baseline indicates an improvement from Baseline.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    08 May 2007
    A global protocol amendment was issued on 08 May 2007 in response to Food and Drug Administration (FDA) feedback on the N01253 final protocol. The following changes were implemented; no subjects were enrolled at the time: • One step was added in the Down-Titration Scheme to reduce subjects from BRV 50 mg/day to BRV 20 mg/day before entering the Study Drug-Free Period. For subjects not entering the LTFU study and taking doses of BRV 50 mg/day, 100 mg/day, or 150 mg/day (or corresponding matching PBO) a down-titration of 1, 2, or 3 weeks, respectively, was required prior to entering the Study Drug-Free Period. • Addition of a clinic visit requiring a complete safety evaluation, including laboratory safety assessments and electrocardiogram (ECG), at 2-weeks after randomization. • Addition of microscopy evaluations for all urinalysis assessments.
    08 May 2007
    In order to harmonize the 3 studies for the BRV POS Phase 3 program, the following changes were applied for N01254: • One step was added in the Down-Titration Scheme to reduce subjects from BRV 50 mg/day to BRV 20 mg/day before entering the Study Drug-Free Period. • An ECG was added at Visit (V) 3 (2 weeks after randomization). • Laboratory safety assessments, pregnancy test (if applicable), AED plasma level, and BRV plasma level were added at V3 (2 weeks after randomization). • Weight was also measured at V3. Other changes implemented in this amendment include: • Details of the statistical methods used to analyze the Type IC/Type I seizure frequency ratio were removed from the protocol. A reference to the statistical analysis plan (SAP) was added. • The definition of a completed subject was clarified. A subject completed the study if either he/she was randomized, underwent the Evaluation Visit (V8), did not have any Early Discontinuation Visit (EDV), and entered the LTFU study; or was randomized, underwent the V8 and Safety Visit (SV), did not have any EDV, and did not enter the LTFU study. Otherwise, the subject was considered discontinued. • Specifications for the handling of missing data for primary efficacy analysis on the Intent-to-Treat (ITT) Population were added. The primary efficacy analysis assumes that subjects who prematurely withdrew from the Treatment Period had the same seizure frequency for the remaining unobserved period. In addition, a sensitivity analysis was further described in the SAP. • Additional instructions for blood sampling volumes for laboratory assessments and genotyping were added.
