Arm Intervention/treatment
Experimental: Brivaracetam

The subjects will be treated with Brivaracetam (BRV) tablets 200 mg/day during 12 weeks: four 25 mg tablets, twice daily.

Based on the Investigator's judgement, at any time, the dose can be decreased to BRV 150 mg/day, 100 mg/day, or 50 mg/day. Flexible dosing, can be up- and down-titrated as needed.

At the end of the Treatment Period, the subject will either enter the N01372 long-term follow-up study or down-titrate during 4 weeks.

 Drug: Brivaracetam


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Subjects Who Achieved a Clinically Meaningful Reduction of Nonpsychotic Behavioral Side Effects Based on the Investigator's Overall Assessment From Study Entry to the End of the Treatment Period [ Time Frame: From Study Entry (Visit1, Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]

    Nonpsychotic behavioral side effects include (but are not limited to) such symptoms as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, irritability, etc.

    The Investigator completed the assessment by answering the following:

    "Has there been a clinically meaningful reduction of nonpsychotic behavioral side effects since the start of BRV?"

    - Yes/No



Secondary Outcome Measures :
  1. Shift in the Maximum Intensity From Baseline to the End of the Treatment Period for Side Effects Primarily Associated With Discontinuation of Levetiracetam (LEV) as Determined by the Investigator [ Time Frame: From Baseline (maximum of 12 weeks prior to Study Entry at Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]
    Nonpsychotic behavioral side effects include (but are not limited to) such symptoms as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, irritability, etc.

  2. Change From Study Entry in Nonpsychotic Behavioral Side Effects to the End of the Treatment Period/Early Discontinuation Visit, Measured by Means of the Investigator Global Evaluation of Nonpsychotic Behavioral Side Effects (I-GEBSE) Scale [ Time Frame: From Study Entry (Visit1, Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]

    There are seven levels for the I-GEBSE:

    • Marked improvement
    • Moderate improvement
    • Slight improvement
    • No change
    • Slight worsening
    • Moderate worsening
    • Marked worsening

  3. Number of Subjects Who Have a Complete Abatement of Nonpsychotic Behavioral Side Effects for the Last Assessment During the Treatment Period, Based on the Investigator's Overall Assessment [ Time Frame: From Baseline (maximum of 12 weeks prior to Study Entry at Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]
    Nonpsychotic behavioral side effects include (but are not limited to) such symptoms as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, irritability, etc.

  4. Number of Subjects Who Are Free From Nonpsychotic Behavioral Side Effects Over the Entire Treatment Period [ Time Frame: From Visit 2 (Week 0) to Visit 6 (Week 12) ]
    Nonpsychotic behavioral side effects (NBSE) include (but are not limited to) such symptoms as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, irritability, etc.

  5. Incidence of Treatment Emergent Adverse Events During the Study Period [ Time Frame: From Study Entry (Visit1, Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]
    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. A treatment emergent AE is any event that emerges during treatment having been absent pre-treatment, or worsens relative to the pre-treatment state.

  6. Withdrawal Due to an Adverse Event (AE) During the Study Period [ Time Frame: From Study Entry (Visit1, Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]
    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.

  7. Occurrence of Serious Adverse Events During the Study Period [ Time Frame: From Study Entry (Visit1, Week -1) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]
    A serious adverse event is any untoward medical occurrences in a subject administered study treatment, whether or not the event is related to treatment, with at least one of the follow outcomes: death, life-threatening, initial inpatient hospitalization or prolongation of hospitalization, significant or persistent disability/incapacity, congenital anomaly/birth defect, or an important medical event that may jeopardize the subject and require a medical/surgical intervention.

  8. Partial Onset Seizure (POS) Frequency Over the Treatment Period for Subjects With Focal Epilepsy [ Time Frame: From 4 weeks prior to Visit 2 (Week 0) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]

    The POS frequency is standardized to a 28-day duration and changes in POS frequency are measured relative to the reported seizure counts for the 4 weeks prior to Visit 2 (Week 0).

    Partial seizures can be classified into one of the following three groups:

    • Simple partial seizures (IA)
    • Complex partial seizures (IB)
    • Partial seizures evolving to secondarily generalized seizures (IC)

  9. Generalized Seizure Days Over the Treatment Period for Subjects With Idiopathic Generalized Epilepsy [ Time Frame: From 4 weeks prior to Visit 2 (Week 0) to the end of the Treatment Period (Visit 6, Week 12) or Early Discontinuation Visit ]

    Generalized seizure days are standardized to a 28-day duration and changes in generalized seizure days are measured relative to the reported seizure counts for the 4 weeks prior to Visit 2 (Week 0).

    Generalized seizures (Type II) include the following seizure types:

    • Absence (IIA1)
    • Atypical absence (IIA2)
    • Myoclonic (IIB)
    • Clonic (IIC)
    • Tonic (IID)
    • Tonic-clonic (IIE)
    • Atonic (IIF)

    A specific effect of BRV on the occurrence of generalized seizures was not assessed.

  • Subject whose seizures could not be reliably counted on a regular basis due to their fast and repetitive occurrence (clusters or flurries)
  • Subject has history or presence of status epilepticus during the year preceding Visit 1 or during Baseline
  • Subject has history or presence of known psychogenic nonepileptic seizures
  • Subject has any clinical conditions (eg, bone marrow depression, chronic hepatic disease, and/or severe renal impairment) which impair reliable participation in the study or necessitate the use of medication not allowed by protocol
