Zebinix(R) Now Available in Greece
Hatfield, England (ots/PRNewswire) - Zebinix(R) (eslicarbazepine acetate), an add-on (adjunctive) therapy for adults with partial-onset seizures, with or without secondary generalisation (where the seizure extensively affects consciousness of the patients by propagation to both sides of the brain), has recently been launched in Greece by Arriani Pharmaceuticals, Eisai's chosen partner in Greece.
In April 2009, the European Commission approved Zebinix(R) based on data showing that it reduces seizure frequency and improves health-related quality of life.,
An estimated 100,000 people are affected by epilepsy in Greece. Epilepsy is one of the most common neurological diseases and successful treatment of partial-onset seizures (the most common type of epilepsy) remains a challenge. Up to 30% of patients with partial seizures do not achieve remission despite appropriate therapy with anti-epileptic drugs.
"There are many patients with epilepsy that do not see an improvement in seizure control with existing anti-epileptic drugs. The launch of Zebinix(R) in Greece permits a wider choice of anti-epileptic drugs to be better matched to the individual patient. Zebinix(R) is shown to decrease seizure frequency and improve health-related quality of life for patients with poor seizure control. Eisai's human health care mission gives first thought to patients and their families to improve their quality of life by bringing valuable treatment that health care provides" commented Dr. Bettina Bauer, Head of EU Epilepsy Business Unit, Eisai Europe Ltd.
Since its launch in mid 2009, Zebinix(R) had over 21,000 months of patient exposure. Zebinix(R) is already available in Germany, Austria, United Kingdom, Denmark, Norway, Iceland, Sweden, Portugal*, Albania*, Cyprus*, Malta*, Spain (co promotion with BIAL, the developer of Zebinix (R)), Republic of Ireland and Greece.
* Exclusively by BIAL
Notes to Editors
Zebinix(R) is the EU trade name for eslicarbazepine acetate.

About epilepsy, partial-onset seizures and their treatment
Epilepsy is a chronic neurological disease characterised by abnormal discharges of neuronal activity causing seizures. Depending on the seizure type, seizures may be limited to one part of the body, or may be generalised to involve the whole body. Patients may also experience abnormal sensations, altered behaviour or altered consciousness. Epilepsy is a disorder with many possible causes. Often the cause of epilepsy is unknown. However, anything that disturbs the normal pattern of neuron activity - from illness to brain damage to tumours, can lead to seizures.
Epilepsy is characterised by abnormal firing of impulses from nerve cells in the brain. In partial-onset seizures, these bursts of electrical activity are initially focused in specific areas of the brain, but may become more generalised;7 the symptoms vary according to the affected areas.
Treatment of partial-onset seizures, the most common type of epilepsy, presents a constant challenge - Up to 30% of patients with partial seizures do not achieve remission despite appropriate therapy with anti-epileptic drugs.
Furthermore, central nervous system related adverse events, such as lightheadedness (dizziness), somnolence (sleepiness), and cognitive slowing (attention and memory deficits), are highly prevalent with existing anti-epileptic agents.,, Hence, there is a need for new anti-epileptic agents that offer effective reduction in seizure frequency combined with a favourable safety profile.
About Zebinix(R) (eslicarbazepine acetate)
Zebinix(R) is indicated as adjunctive therapy in adults with partial-onset seizures with or without secondary generalisation.1 Zebinix(R) is a novel, once-daily, voltage-gated sodium channel blocker., It preferably targets the inactivated state of the sodium ion channel, preventing its return to the active state, and thereby reduces repetitive neuronal firing. The efficacy of Zebinix(R) was demonstrated in an initial proof-of-concept phase II study and three subsequent phase III randomised, placebo controlled studies in 1049 patients with refractory partial onset seizures.,, Zebinix(R) also significantly improved patient's health related quality of life (HRQoL) as measured by the QOLIE-31 score during a one year open label extension of the above three studies.,,,,
The EU approval was based on data from a phase II and three phase III clinical trials.5,14,15,16 Patients recruited in the phase III trials had a history of at least four partial seizures per month despite treatment with up to three concomitant anti-epileptic drugs.,,
During the trials, patients were randomised to various dosages of Zebinix(R) or placebo and after a 2-week titration period, were assessed over a 12-week maintenance period, with continued follow-up over a one year open-label period.,,
Over the 12-week maintenance period, Zebinix(R) 800mg and 1200mg once-daily significantly reduced seizure frequency, and was significantly more effective than placebo.12,15,16,22 Long-term safety and maintenance of therapeutic effect was demonstrated in one-year open-label extensions of these studies.,,
Tolerability and drug interactions,,,,,
In the Phase II and III clinical trials adverse events mainly occurred during the first 6 weeks of treatment and the majority of patients experienced adverse events of mild to moderate intensity. During the first few weeks of treatment there were no observed differences in the incidence of side effects between patients treated with Zebinix(R) and the placebo group. The most common treatment-emergent adverse events in the pivotal studies were dizziness, headache and somnolence.
Quality of life and depressive symptoms,,,,
The effect of Zebinix(R) on quality of life was assessed using the Quality of Life Epilepsy Inventory-31 (QOLIE-31) scale. There was a statistically and clinically significant improvement from baseline during long-term open-label therapy, including a mean relative improvement in overall quality of life (p<0.001 - p<0.01 across the three studies) and improvements in individual elements of the QOLIE-31 scale including seizure worry, emotional wellbeing, energy/fatigue, medication effects and social function.
Improvement in depressive symptoms was also measured using the Montgomery Asberg Depression Rating Scale (MADRS). During long-term, open-label therapy, Zebinix(R) demonstrated a statistically significant improvement from baseline in the overall MADRS score (p<0.0001) and individual domains of the MADRS scale including pessimistic thoughts, concentration difficulties, apparent sadness and inner tension.
Eisai Europe Limited , a European subsidiary of Eisai Co., Ltd. , announced in February 2009 that it had entered into a license and co-promotion agreement with BIAL - Portela & C(a), S.A. (Headquarters: Sao. Mamede do Coronado, Portugal, Chairman: Luis Portela & CEO: Antonio Portela, "BIAL"), which gave Eisai Europe Limited rights to sell BIAL's anti-epileptic drug Zebinix(R) (eslicarbazepine acetate) in Europe.
