HATFIELD, England, February 4, 2016 /PRNewswire/ --

Eisai enter into a new agreement with Esteve, a Spanish pharmaceutical company with a comprehensive neurology franchise, to co-promote Fycompa^® (perampanel) in Spain from February 2016. Eisai and Esteve will launch the new indication for the adjunctive treatment of primary generalised tonic-clonic (PGTC) seizures in adults and adolescents (≥12 years) with idiopathic generalised epilepsy (IGE) in Spain in early 2016. Perampanel is also indicated in Spain for the adjunctive treatment of partial onset seizures, with or without secondarily generalised seizures, in patients with epilepsy aged 12 years and older.^[1]

"We are pleased to further strengthen our relationship with Esteve under this new agreement to co-promote perampanel. This collaboration will ensure that we maximise access to our products for people with epilepsy [per indication] in Spain," comments Gary Hendler, President and CEO, Eisai EMEA.

"The new collaboration with Eisai under the agreement to co-promote perampanel in Spain will further consolidate our presence in neurology, one of our priority areas, and allow us to continue our efforts to bring epilepsy treatments to patients who need them," says Joe Sullivan, Managing Director of Esteve Farma.

Epilepsy is a common neurological condition that causes recurrent seizures in the brain.^[2] It is usually diagnosed in children and people over 65 years of age, although it can affect anyone.^[2] Currently, up to 22,000 people are diagnosed with epilepsy each year in Spain, of whom around one third have seizures that are not completely controlled by their anti-epileptic therapy.^[3]

The new agreement with Esteve in Spain demonstrates Eisai's commitment in the therapeutic area of epilepsy and further exemplifies the company's contribution to addressing the diversified needs of and increasing the benefits provided to patients and their families as shown by its human health care mission.

Notes to Editors

About Fycompa^® (perampanel)   

Perampanel is a highly selective, non-competitive AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid)-type glutamate receptor antagonist. AMPA receptors, widely present in almost all excitatory neurons, transmit signals stimulated by the excitatory neurotransmitter glutamate within the brain and are believed to play a role in central nervous system diseases characterised by excess neuroexcitatory signalling including epilepsy.

Perampanel is indicated for the adjunctive treatment for partial onset seizures, with or without secondarily generalised seizures, in patients with epilepsy aged 12 years and older and for adjunctive treatment of primary generalised tonic-clonic seizures, in patients with idiopathic generalised epilepsy.

About Epilepsy    

Epilepsy is one of the most common neurological conditions in the world, affecting approximately six million people in Europe, and an estimated 50 million people worldwide.^[4] It is a collection of syndromes that have many possible causes but often the cause is unknown. Epilepsy is a chronic disorder of the brain that affects people of all ages. It is characterised by abnormal discharges of neuronal activity causing 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.

For the majority of idiopathic generalised epilepsy patients, a primary generalised tonic-clonic (PGTC) seizure begins with or without an aura, which is followed by rigid muscle. This leads to violent muscle contraction (clonic phase) and a loss of consciousness. As this is a serious event, it is seen as a major hindrance on daily life. While the seizure generally only lasts a few minutes, the patient will often feel confused or drowsy for a short period of time before returning to normal.^[5],[6]  PGTC seizures can also result in risk of injury and sudden unexplained death in epilepsy (SUDEP).^[7]
