E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety and tolerability of brivaracetam at individualized doses with a maximum of 150 mg/day in subjects suffering from epilepsy. To evaluate the maintenance of efficacy over time of brivaracetam. To explore impact on health-related quality of life. To collect data on medical resources used and on indirect costs. This open long-term follow-up trial will give subjects suffering from epilepsy, who may have benefited from brivaracetam as adjunctive treatment in previous trials, the opportunity to continue brivaracetam treatment after completion of an initial study giving access to the present trial. |

E.2.2 | Secondary objectives of the trial |
To evaluate the maintenance of efficacy over time of brivaracetam. |

E.3 | Principal inclusion criteria |
1. An Independent Ethic Committee / Institutional Review Board IEC/IRB approved written informed consent signed and dated by the subject or legally acceptable representative s . The consent form or a specific assent form will be signed and dated by minors, according to country-specific regulations. 2. Male/female subjects from 16 years or older. Subjects under 18 years may only be included where legally permitted and ethically accepted. 3. Inpatients or outpatients with epilepsy who were treated with brivaracetam in previous trials / programs which allow access to the present trial. 4. Subjects for whom the Investigator believes a reasonable benefit from the long-term administration of brivaracetam may be expected. 5. Female subjects without childbearing potential premenarcheal; 2 years post-menopausal; bilateral oophorectomy or ovariectomy; bilateral salpingectomy, complete hysterectomy; congenital sterility are eligible. Female subjects with childbearing potential are eligible if they use a medically accepted contraceptive method for the duration of the trial participation Intra Uterine Device; diaphragm with spermicide; male or female condom with spermicide; oral hormonal contraceptive; non- oral hormonal contraceptive medication; bilateral tubal ligation; monogamous relationship with vasectomized partner . In particular, oral or depot contraceptive treatment with at least 30 g or 50 g if associated with carbamazepine CBZ or other strong enzyme inducing drugs ethinylestradiol per intake 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. 6. Subject/legally acceptable representative considered as reliable and capable of adhering to the protocol e.g.; 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 having clinically significant deviations from reference range values for laboratory parameters creatinine clearance 50 mL/min, platelets 100,000/uL, or neutrophils cells 1800/uL . Poor compliance with visit schedule or medication intake in previous brivaracetam trial. Impaired hepatic function ALAT/SGPT, ASAT/SGOT, alkaline phosphatase, gammaGT value of more than three times the upper limit of the reference range. Participation in any clinical trial of another investigational drug or device during the study. Pregnant or lactating woman. |

E.5 End points |
E.5.1 | Primary end point(s) |
Criteria for efficacy evaluation ITT POS population The primary efficacy variable is based on the seizure frequency per week for POS type I by 3-month periods over the Evaluation Period V1 until the last evaluation visit . Seizure frequency per week will be derived from the seizure count information recorded on the DRC and is defined as the number of epileptic seizures standardized to a seven day period. It is computed as the number of epileptic seizures recorded over the period, divided by the total number of days in that period, multiplied by 7. ITT ULD population The efficacy variables are the percent reduction from the pivotal trials baseline on the Myoclonus Patient Questionnaire Section 1 of the UMRS - unified myoclonus rating scale , the Action Myoclonus Section 4 and the Functional test Section 5 scores as assessed at every FEV full evaluation visit , YEV yearly evaluation visit , FV final visit or EDV early discontinuation visit by the investigator. |
