Wealth of Data for Fycompa® (perampanel) and Inovelon® (rufinamide) to be Presented at the American Epilepsy Society (AES) Annual Meeting


Data from nine abstracts for Eisai's epilepsy treatments perampanel and rufinamide will be presented at the 70th Annual Meeting of the American Epilepsy Society (AES), 2-6 December, Houston, Texas, which provide further insight into their long-term use in people with epilepsy.

Perampanel is indicated in the European Union for patients aged 12 years and older, for adjunctive treatment of partial-onset seizures (POS), with or without secondarily generalised seizures, and for adjunctive treatment of primary generalised tonic-clonic (PGTC) seizures in patients with idiopathic generalised epilepsy (IGE).[1]

Rufinamide is indicated in the European Union for the adjunctive treatment of seizures associated with Lennox-Gastaut Syndrome in patients with epilepsy aged four years and older.[2]

"These data provide real world insights into the activity of perampanel and rufinamide in potential patients over a wide range of ages. Through new and continued research with perampanel and rufinamide, we aim to further educate the epilepsy community about these debilitating diseases," comments Lynn Kramer, MD, Chief Clinical Officer and Chief Medical Officer, Neurology Business Group, Eisai.

The development of its epilepsy portfolio 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. Eisai is committed to the therapeutic area of neurology and to address the unmet medical needs of people with neurological conditions and their families.

Notes to Editors

About Fycompa® (perampanel)

Perampanel is a first-in-class, non-competitive AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) glutamate receptor antagonist on post-synaptic neurons.[1] 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.[3] Since launch, approximately 52,000 people living with epilepsy have been treated with perampanel.[4]

About Inovelon® (rufinamide)

Rufinamide is a triazole derivative that is structurally unrelated to currently marketed antiepileptic drugs (AEDs).[5],[6] It is believed to regulate the activity of sodium channels in the brain which carry excessive electrical charges.[5] Rufinamide was approved for adjunctive therapy for seizures associated with Lennox-Gastaut Syndrome in Europe (under the brand name Inovelon) in 2007 in patients four years of age and older. Rufinamide is available as film-coated tablets containing 100mg, 200mg and 400mg rufinamide and as a 40mg/ml oral suspension.[2]

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.[7] 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 nature and 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.

About Eisai EMEA in Epilepsy

Eisai is committed to developing and delivering highly beneficial new treatments to help improve the lives of people with epilepsy. The development of AEDs is a major strategic area for Eisai in Europe, the Middle East, Africa, Russia and Oceania (EMEA).

In the EMEA region, Eisai currently has four marketed treatments including:

- Fycompa® (perampanel) is indicated for use as a once-daily, 
  adjunctive treatment for both primary generalised tonic-clonic 
  seizures in idiopathic generalised epilepsy and for partial onset 
  seizures, with or without secondary generalisation, in patients 
  aged 12 years or older
- Inovelon® (rufinamide) is indicated for the adjunctive treatment of
  seizures associated with Lennox-Gastaut Syndrome in patients >=4 
  years. (Rufinamide was originally developed by Novartis)
- Zonegran® (zonisamide) as monotherapy in the treatment of partial 
  seizures, with or without secondary generalisation, in adults with 
  newly diagnosed epilepsy and as adjunctive therapy in the treatment
  of partial seizures, with or without secondary generalisation, in 
  adults, adolescents and children aged six years and above. 
  (Zonegran is under license from the originator Dainippon Sumitomo 
- Zebinix® (eslicarbazepine acetate) as adjunctive treatment in adult
  patients with partial onset seizures, with or without secondary 
  generalisation (Zebinix is under license from Bial)
