HATFIELD, England, January 20, 2015 /PRNewswire/ --
PRESS RELEASE FOR EU MEDIA ONLY: NOT FOR SWISS/U.S. JOURNALISTS
Novel, anti-epilepsy treatment Exalief® will soon be available in Russia. (Exalief is also marketed under the trade name Zebinix in Europe). Once-daily eslicarbazepine acetate is indicated in Europe as adjunctive therapy in adults with partial onset seizures, with or without secondary generalisation.
"Eslicarbazepine acetate will provide doctors with a new, easy to titrate, adjunctive therapy with a beneficial safety profile to help those with inadequately controlled partial onset epilepsy to improve their condition. Approximately one third of people with epilepsy do not achieve adequate control of epileptic seizures whilst taking their first antiepileptic drug, so there is a continued need for additional effective options," commented Professor Pavel Vlasov, Neurology and Neurosurgery department at the Moscow State University of Medicine and Stomatology.
Epilepsy is one of the most common neurological conditions in the world. Around three out of every 1,000 people in Russia live with the condition, 82% of which have partial epilepsy. Despite many anti-epileptic drugs (AEDs) available, the successful treatment of partial onset seizures remains a significant challenge in some patients. Currently, between 20-40% of patients with newly diagnosed epilepsy will become refractory to treatment.
Eslicarbazepine acetate, a sodium channel blocker that differentially and selectively targets slow inactivated sodium channels, was approved by the European Commission in 2009 based on data submitted which showed that it reduces seizure frequency by up to 45% in patients with partial epilepsy.,, Long-term studies also show that up to 18% of patients achieved seizure freedom with eslicarbazepine acetate,, while a phase IV study (n=254) demonstrated that 48% of patients became seizure free and 82% of patients stayed on treatment over a six month period when Exalief was prescribed as a first-line adjunctive treatment. A long-term open-label extension study demonstrated a statistically significant improvement in quality of life from baseline, including seizure worry, energy/fatigue, medication effects and cognitive and social function. Eslicarbazepine acetate also shows a maintained activity in human tissue in which resistance to carbamazepine is observed.
"We are delighted that once-daily Exalief will soon be launched in Russia and will provide an effective and well tolerated alternative treatment to help people with epilepsy manage their seizures. Eisai is committed to provide effective treatments to patients to help improve their quality of life, as underscored by our human health care mission," commented Olga Konopleva, Managing Director, Eisai Russia.
The continued development of eslicarbazepine acetate underscores Eisai's human health care (hhc) mission, the company's commitment to innovative solutions in disease prevention, cure and care for the health and wellbeing of people worldwide. Eslicarbazepine acetate is already available in Albania*, Austria, Czech Republic, Cyprus*, Denmark, England, Finland, France, Germany, Greece, Iceland, Italy, Malta*, Norway, Portugal*, Republic of Ireland, Scotland, Sweden, Finland, Spain (co-promotion with BIAL, the developer of eslicarbazepine acetate), Wales and the U.S**.
*Exclusively by BIAL
**Eslicarbazepine acetate is sold in the U.S. under the trade name APTIOM®

About Exalief®(eslicarbazepine acetate)
Eslicarbazepine acetate is indicated as adjunctive therapy in adults with partial onset seizures, with or without secondary generalisation.The clinical trial programme is also underway for eslicarbazepine acetate as a paediatric and monotherapy treatment.
Eslicarbazepine acetate is a voltage-gated sodium channel blocker. It selectively targets the slow inactivated state of the sodium ion channel, (which have been implicated in the pathogenesis of epilepsy), preventing its return to the active state, and thereby reduces repetitive neuronal firing. Further, eslicarbazepine acetate does not inhibit potassium efflux, which may reduce the potential for repetitive neuronal firings. The efficacy of eslicarbazepine acetate 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.,,

Epilepsy is one of the most common neurological conditions in the world, affecting approximately eight in 1,000 people in Europe, and an estimated 50 million people worldwide., Epilepsy is a chronic disorder of the brain that affects people of all ages. It is characterised by abnormal discharges of neuronal activity which causes seizures. Seizures can vary in severity, from brief lapses of attention or jerking of muscles, to severe and prolonged convulsions. Depending on the seizure type, seizures may be limited to one part of the body, or may involve the whole body. Seizures can also vary in frequency from less than one per year, to several per day. Epilepsy has many possible causes but often the cause is unknown.
