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
    To evaluate the long-term safety and tolerability of brivaracetam (BRV) at individualized doses up to a maximum of 200 mg/day as adjunctive treatment in adult subjects with epilepsy.
    Protection of trial subjects
    During the course of the study all subjects were closely monitored. The following safety parameters were assessed at 6 month intervals: • Vital signs • Physical Exam • Neurological Exam • Psychiatric and mental status • Electrocardiogram (ECG) • Seizure assessment • Laboratory assessment • Pregnancy • Review of Adverse Events(AEs)/Medical Procedures • Suicidality Assessment • Quality of Life (QOL) Assessment There are withdrawal criteria specified within the protocol: • Worsening of seizures • Lack/Loss of efficacy • Non-compliance • Prohibited Concomitant Medication • Pregnancy • Significant Liver Function Test (LFT) results • Illness (interfering with continued study participation) • Suicidal ideation • Withdrawal of consent • Lost to follow-up • Sponsor/agency request
    Background therapy
    		 Background antiepileptic drug (AED) therapy was permitted as described in the protocol.

    Arm description
    		 This arm includes subjects with focal epilepsy, who received a flexible dose of Brivaracetam (BRV) tablets, administered twice a day, starting with an individual dose that they had reached at the completion of study N01395 (feeder study). The BRV dose could have been increased or decreased in increments of 50mg/day based on the individual subject’s seizure control and/or tolerability, but was to not exceed 200mg/day.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    14 Nov 2013
    This Amendment was implemented after the date of first subject first visit (FSFV, 25 subjects had enrolled in the study as of the date of this amendment). The rationale for this amendment was to clarify that data for the following variables were to only be collected and analyzed for subjects with epilepsy that entered N01372 from a study in which a Baseline value for that variable was previously collected: - Percent reduction in Type I partial-onset seizures (POS) frequency per 28 days from Baseline of the previous study into the Evaluation Period - Responder rate in POS (Type I) frequency over the Evaluation Period - Percent reduction in generalized (Type II) seizure days per 28 days from Baseline of the previous study to the Evaluation Period - Responder rate for generalized (Type II) seizure days over the Evaluation Period - Patient Weighted Quality of Life in Epilepsy Inventory-Form 31 (QOLIE-31-P) score - Hospital stays and healthcare provider consultations. Additionally, Inclusion Criterion 7 was added, which required subjects to be able to take the oral film-coated tablets of Brivaracetam (BRV). References to specific BRV studies were removed and a statement was added to clarify that the study was to enroll subjects who had completed the Treatment Period of an applicable BRV study. Administrative changes included an update to the Clinical Trial Biostatistician and Study Physician.
