E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety and tolerability of BRV at individualized doses up to a maximum of 200mg/day in epilepsy subjects. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the maintenance of efficacy of BRV over time. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• An Independent Ethics Committee (IEC)/Institutional Review Board (IRB) approved written informed consent signed and dated by the subject or by parent(s) or legally acceptable representative. The consent form or a specific assent form, where required, will be signed and dated by minors. In countries and sites where a DNA analysis is accepted, an additional Informed Consent form will have to be signed by subjects coming from N01358. Deoxyribonucleic acid analysis will be performed only in adults, and the subject can withdraw consent to the use of the sample at any time. Mentally impaired subjects will be excluded. In case the consent is withdrawn, the site must request the destruction of the sample.
• Male/female subject from 16 years or older. Subject under 18 years may only be included where legally permitted and ethically accepted.
• Subject completed the Treatment Period of N01358 or the Evaluation Period of N01258.
• Subject for whom the Investigator believes a reasonable benefit from the long-term administration of BRV may be expected.
• Female subject without childbearing potential (premenarcheal, postmenopausal for at least 2 years, bilateral oophorectomy or tubal ligation, complete hysterectomy) are eligible. Female subject with childbearing potential are eligible if they use a medically accepted contraceptive method. Oral or depot contraceptive treatment with at least ethinylestradiol 30μg per intake (or ethinylestradiol 50μg per intake if associated with any strong enzyme inducer [eg, carbamazepine, phenobarbital, primidone, phenytoin, oxcarbazepine, St. John’s Wort, rifampicin]), monogamous relationship with vasectomized partner, or double-barrier contraception are acceptable methods. The subject must understand the consequences and potential risks of inadequately protected sexual activity, be educated about and understand the proper use of contraceptive methods, and undertake to inform the Investigator of any potential change in status. Abstinence will be considered as an acceptable method of contraception if the Investigator can document that the subject agrees to be compliant.
• Subject/legally acceptable representative considered as reliable and capable of adhering to
the protocol (eg, able to understand and complete diaries and questionnaires), visit schedule, or medication intake according to the judgment of the Investigator. |
|
E.4 | Principal exclusion criteria |
• Subject has developed hypersensitivity to any components of the investigational medicinal product (IMP) or comparative drugs as stated in this protocol during the course of the core studies
• Severe medical, neurological, or psychiatric disorders, or laboratory values which may have an impact on the safety of the subject
• Poor compliance with the visit schedule or medication intake in the previous BRV studies
• Planned participation in any other clinical study of another investigational drug or device during this study
• Pregnant or lactating woman
• Any medical condition which, in the Investigator’s opinion, warrants exclusion
• Subject has a lifetime history of suicide attempt (including an active attempt, interrupted attempt, or aborted attempt), or has suicidal ideation in the past 6 months as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) at Screening. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective is to evaluate the long-term safety and tolerability of BRV at individualized doses up to a maximum of 200mg/day in epilepsy subjects. Safety variables are AEs, laboratory tests (including hematology, blood chemistry, urinalysis, endocrinology and pregnancy test), ECG, physical examination, neurological examination, vital signs, and body weight. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Continuously observed throughout the study. |
|
E.5.2 | Secondary end point(s) |
To evaluate the maintenance of efficacy of BRV over time. The primary efficacy variable is the POS (type I) seizure frequency standardized to a 28 day duration. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
This will be summarized by 3 month periods over the Evaluation Period. |
