Outcome Measures
Primary Outcomes (2)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) During the Study
TEAEs are defined as AEs that had onset on or after the day of first BRV dose.
From Baseline to end of study (up to 10 years)
Percentage of Participants With Treatment-emergent Serious Adverse Events (SAEs) During the Study
TEAEs are defined as AEs that had onset on or after the day of first BRV dose. A SAE was defined as an event that met 1 or more of the below criteria: a) Death, b) Life-threatening, (Life-threatening did not include a reaction that might have caused death had it occurred in a more severe form.) c) Significant or persistent disability/incapacity, d) Congenital anomaly/birth defect (including that occurring in a fetus), e) Important medical event that, based upon appropriate medical judgment, may have jeopardized participant and may have required medical or surgical intervention to prevent 1 of the other outcomes listed in the definition of serious, (Important medical events may have included allergic bronchospasm requiring intensive treatment in an emergency room \[ER\] or at home) f) Initial inpatient hospitalization or prolongation of hospitalization. (A participant admitted to a hospital, even if released on the same day, met the criteria for the initial inpatient hospitalization).
From Baseline to end of study (up to 10 years)
Secondary Outcomes (9)
Absolute Change in 28-days Adjusted Partial-onset-seizure (POS) Frequency for Participants Aged ≥2 Years From Baseline to the End of the Evaluation Period in Participants With POS Only (Based on Daily Record Card [DRC])
From Baseline (LTFU participants: Baseline of previous studies N01263 [NCT00422422]; and DE participants: Baseline of current study) to the end of the evaluation period (up to 10 years)
Percent Change in 28-days Adjusted Partial-onset-seizure (POS) Frequency for Participants Aged ≥2 Years From Baseline to the End of the Evaluation Period in Participants With POS Only (Based on DRC Data)
From Baseline (LTFU participants: Baseline of previous studies N01263 [NCT00422422]; and DE participants: Baseline of current study) to the end of the evaluation period (up to 10 years)
50% Responder Rate for Participants ≥2 Years of Age for Total Seizures (All Types) (Based on DRC Data)
From Baseline (LTFU participants: Baseline of previous studies N01263 [NCT00422422]; and DE participants: Baseline of current study) to the end of the evaluation period (up to 10 years)
Absolute Change in Average Daily Frequency (ADF) of Partial-onset-seizures (POS) in Participants <2 Years of Age With POS Only (Based on EEG Data)
From Baseline (LTFU participants: Baseline of previous studies N01263 [NCT00422422] or N01349 [NCT03325439]) to the end of the evaluation period (up to 10 years)
Percent Change in Average Daily Frequency (ADF) of Partial-onset-seizures (POS) in Participants <2 Years of Age With POS Only (Based on EEG Data)
From Baseline (LTFU participants: Baseline of previous studies N01263 [NCT00422422] or N01349 [NCT03325439]) to the end of the evaluation period (up to 10 years)

Study Arms (1)
Brivaracetam
EXPERIMENTALInterventions
The max BRV dose will be 5.0 mg/kg/day, not to exceed a dose of 200 mg/day for subjects with body weight \>40kg. Subjects may receive oral solution or oral tablets. The LTFU subjects will start dosing in N01266 on the individualized BRV dose they were receiving at the completion of the core study. Subjects must be able to tolerate the min BRV dose specified in the core study to be eligible for entry into the Evaluation Period of N01266. Dose can be adjusted as considered necessary by the Investigator and required by the subject's medical condition. All subjects who prematurely discontinue the study should complete an EDV and have their BRV dose down titrated by a maximum of half the dose every week for a maximum of 4 weeks until a dose of 1 mg/kg/day (50 mg/day for subjects with body weights \>50kg) is reached.
Eligibility Criteria
You may qualify if:
- All Subjects:
- Informed Consent form (ICF) is signed and dated by the parent(s) or legal representative(s)
- Subject/legal representative is considered reliable and capable of adhering to the protocol
- For female subjects:
- Subject is not of childbearing potential
- OR if women of childbearing potential, and sexually active only if:
- Adequate Contraceptive method
- Negative pregnancy test
- Understands the consequences and potential risks of inadequately protected sexual activity, understands and properly uses contraceptive methods, and is willing to inform the Investigator of any contraception changes
- Long Term Follow-up Subjects:
- \- Male or female subjects having participated in a core study with a confirmed diagnosis of epilepsy and for whom a reasonable benefit from long-term administration of BRV is expected
- Directly Enrolled Subjects:
- Subject is a male or female ≥4 years to \<17 years of age
- Subject has a clinical diagnosis of partial-onset seizures (POS) according to the International League Against Epilepsy (ILAE) classification
- Subject has an EEG compatible with the clinical diagnosis of POS
- +3 more criteria
You may not qualify if:
- All Subjects:
- Subject is a pregnant or nursing female
- Subject has severe medical, neurological, or psychiatric disorders or laboratory values, which may have an impact on the safety of the subject.
- Subject has planned participation in any clinical study of another investigational drug or device.
- Subject has chronic liver disease.
- Long Term Follow-up Subjects:
- Subject had hypersensitivity to BRV or excipients or comparative drugs as stated in this protocol during the course of the core study.
- Subject had poor compliance with the visit schedule or medication intake in the core study.
- Subject ≥6 years of age has a lifetime history of suicide attempt (including actual attempt, interrupted attempt, or aborted attempt), or has suicidal ideation in the past 6 months as indicated by a positive response ("Yes") to Question 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) at the EV. If a subject has active suicidal ideation without a specific plan as indicated by a positive response ("Yes") to Question 4 of Columbia-Suicide Severity Rating Scale (C SSRS) at the EV, the subject should be referred immediately to a Mental Healthcare Professional and may be excluded from the study based upon the Investigator's judgment of benefit/risk of continuing the subject in the study/on study medication.
- Directly Enrolled Subjects:
- Subject has previously received BRV.
- Subject had concomitant use of LEV at the ScrV. In addition, the use of LEV is prohibited for at least 4 weeks prior to the ScrV.
- Subject has epilepsy secondary to a progressive cerebral disease or tumor, or any other progressively neurodegenerative disease. Stable arteriovenous malformations, meningiomas or other benign tumors may be acceptable according to Investigator's opinion.
- Subject has a history of primary generalized epilepsy.
- Subject has a history of status epilepticus in the month immediately prior to the ScrV or during the Up Titration Period.
- +13 more criteria
