Inovelon(R) a New Treatment for Lennox-Gastaut Syndrome Reduces Drop Attacks by Over 40%

London (ots/PRNewswire) - - First EMEA Licensed Treatment Specifically for LGS Offers New Hope for Patients With Epilepsy Eisai Europe Limited, (Headquarters: London, Chairman and CEO Yutaka Tsuchiya) today announced publication of the results of a major study of its new anti-epileptic agent Inovelon (rufinamide) indicated for adjunctive therapy in Lennox-Gastaut Syndrome (LGS), a severe form of generalised epilepsy that develops in early childhood. In the placebo-controlled study, published in the journal Neurology, Inovelon was found to produce a median reduction in seizure frequency of 42.5% (p=<0.0001) for drop attacks, and reduce the occurrence of total seizures by 32.7% (p=<0.0015). These differences between Inovelon and placebo were observed as early as week two during the study. Results from the extension study suggested that for subjects continuing on Inovelon, seizure reduction appeared to be maintained in the long term (up to two years). Lead study author Dr Tracy Glauser, Professor of Pediatrics and Neurology at Cincinnati Children's Hospital, Ohio said, "Lennox-Gastaut Syndrome is a devastating form of paediatric epilepsy usually resulting in multiple seizures occurring several times a day, and is often associated with impaired mental development. Existing antiepileptics offer only limited seizure control. Also, there may be difficulties with tolerability. "Our study showed that as adjunctive therapy, Inovelon can reduce the number of drop attacks by over 40% and the occurrence of total seizures by nearly a third. We also found that the effect of Inovelon is maintained over the long term," he concluded. The study authors noted that the ability of Inovelon to reduce total and tonic-atonic seizure frequency combined with its good tolerability make it an important addition to the therapeutic options for LGS. Inovelon is a structurally novel compound and is the first treatment licensed by the European Medicines Agency (EMEA) specifically for LGS. Approximately 11,000 people across Western Europe are currently diagnosed with LGS, and it is hoped that Inovelon, used as the first choice adjunctive therapy, will contribute to improved patient and carer quality of life in line with Eisai's commitment to being an hhc (human health care) company. Eisai has several other compounds in development for the treatment of neurological conditions, including epilepsy, in addition to its existing neurology medicines Aricept(R) (donepezil, for the treatment of mild to moderate Alzheimer's disease), and Zonegran(R) (zonisamide, for the treatment of partial epilepsy and secondarily generalised partial epilepsy.) Notes to editors About LGS Symptoms of LGS include a variety of seizure types, with tonic-atonic seizures being the most common. Atonic seizures (rapid loss of muscle tone and consciousness), and tonic seizures (where muscles contract continuously typically producing a stiffening of the legs and arms) lead to the sudden falls seen in LGS patients known as 'drop attacks'. Absence seizures (staring spells) and myoclonic seizures (sudden muscle jerks) are also commonly observed. All children with LGS will experience varying degrees of developmental delay and behavioural problems.
