E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of this open-label long-term follow-up trial is to give subjects with epilepsy, who may have benefited from brivaracetam as adjunctive treatment in a previous trial, the opportunity to continue brivaracetam treatment after completion of an initial study which allowed access to the present 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.
|
|
E.2.2 | Secondary objectives of the trial |
To evaluate the maintenance of efficacy over time of brivaracetam.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• An Independent Ethics Committee (IEC) 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. • Male/female subjects from 16 years or older. Subjects under 18 years may only be included where legally permitted and ethically accepted. • Inpatients or outpatients with epilepsy who were treated with brivaracetam in previous trials / programs which allow access to the present trial. • Subjects for whom the Investigator believes a reasonable benefit from the long-term administration of brivaracetam may be expected. •• 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 µg [or 50 µg 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.
• 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 |
• Severe medical, neurological and psychiatric disorders, or laboratory values which may have an impact on the safety of the subject. • Subject having clinically significant deviations from reference range values for laboratory parameters: creatinine clearance < 50 mL/min, platelets < 100,000/l, or neutrophil cells < 1,800/l). • Poor compliance with visit schedule or medication intake in previous brivaracetam trial. • Impaired hepatic function: ALAT/SGPT, ASAT/SGOT, alkaline phosphatase, GT 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.
If the Investigator has any medically valid reason to doubt the eligibility of a subject, the subject should not be included into the trial. If however, the Investigator has any other kind of doubts concerning the eligibility, he/she should consult the Sponsor’s CRP or representative for clarification.

E.5 End points |
E.5.1 | Primary end point(s) |
Criteria for efficacy evaluation : 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.
The secondary efficacy variables are: • Based on the seizure frequency per week for all epileptic seizures (types I+II+III) by 3-month periods over the Evaluation Period. • Proportion of seizure-free days for all epileptic seizures (types I+II+III) by 3-month period over the Evaluation Period. • Continuously epileptic seizures free subjects for all epileptic seizures types (I+II+III) by 3-month period over the Evaluation Period. • Responder rate in POS (type I) by 3-month periods over the Evaluation period.
The periods considered in the definition of efficacy variables are the following: • 3-month periods over the Evaluation Period (V1 until the last evaluation visit). The exploratory variables are as follows: • Health-Related Quality of Life (QOLIE-31-P) at month 3 during the first year, afterwards once a year at Yearly Evaluation Visit or at Early Discontinuation Visit. • Medical resources used by 3-month periods over the Evaluation Period. • Indirect cost by 3-month periods over the Evaluation period. Safety variables: • Adverse events reporting. • Laboratory tests (including blood and urine). • Electrocardiogram (ECG) measurements. • Physical and neurological examinations. • Vital signs. • Body weight. • Plasma concentration of concomitant AEDs and brivaracetam.
The periods considered in the definition of safety variables are the following: • Evaluation Period (V1 until the last evaluation visit). • Down-titration Period. • Post-treatment Period. Statistical methods : All variables will be analyzed in a descriptive way. No split by study drug dose is foreseen.
