Class A reimbursement granted for Zonegran®(zonisamide) for patients with newly diagnosed epilepsy
Zonegran® (zonisamide) has now received class A reimbursement in Italy as monotherapy for partial seizures (with or without secondary generalisation) in adults with newly diagnosed epilepsy. Monotherapy is defined as treatment with a single drug.
Already available in Italy as adjunctive therapy for the treatment of partial seizures with or without secondary generalisation in patients over the age of 18, once-daily zonisamide is a second generation anti-epileptic drug (AED) with multiple mechanisms of action and a chemical structure unrelated to any other AEDs. Monotherapy is the favoured approach in managing newly diagnosed epilepsy as most people with epilepsy may be successfully managed with the first or second monotherapy. In comparison with polytherapy, monotherapy also reduces the potential for adverse drug interactions.
"Monotherapy is the optimal treatment approach for newly diagnosed epilepsy and zonisamide's proven efficacy in this setting will help people with partial epilepsy to control their seizures commented Professor Michel Baulac, Hopital de la Pitie-Salpetriere, Paris, France and lead investigator in the study which resulted in the approval of zonisamide monotherapy in Europe "This treatment, which is easy to titrate and offers the advantage of once daily dosing, may improve adherence to treatment for people with epilepsy."
In Italy, there are approximately 300,000 people with epilepsy and 25,000 new cases are diagnosed every year. For the majority of people with epilepsy, seizures can be controlled with one AED; however, seizures persist in up to 30% of patients with partial onset epilepsy (the most common form of the condition) despite existing medical therapy.
The efficacy and safety of zonisamide as monotherapy was demonstrated in a double-blind, randomised, multicentre study of 583 newly diagnosed adult partial epilepsy patients, which compared the efficacy and safety of once-daily zonisamide with twice-daily controlled release carbamazepine as monotherapy. The study's primary endpoint was the proportion of seizure-free patients at six months. Zonisamide demonstrated high response rates for achieving seizure freedom in newly diagnosed patients with epilepsy, similar to controlled release carbamazepine. In the majority of patients, seizure freedom was achieved at the target dose of 300 mg with once daily dosing. Zonisamide was considered non-inferior to carbamazepine, was well tolerated, and had no apparent safety concerns after one year of treatment at doses ranging from 300 to 500 mg/day.
"The availability of Zonegran as monotherapy for adults in Italy is a great step forward, giving newly diagnosed people with epilepsy access to another treatment option," said Giuseppe Lo Presti, Epilepsy Business Unit Director, Eisai Italy. "This class A reimbursement also highlights the commitment of the authorities, the patients' associations and Eisai to providing patients and their families with improved quality of life by bringing effective treatments to those that need it."
In addition to monotherapy, zonisamide is indicated in Europe and reimbursed in Italy as adjunctive therapy in the treatment of partial seizures, with or without secondary generalisation, in adults; zonisamide is also indicated in Europe, but not currently reimbursed in Italy, for the adjunctive treatment of partial seizures, with or without secondary generalisation in adolescents and children aged six years and above.
The continued development of zonisamide underscores Eisai's human health care 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 epilepsy and addressing the unmet medical needs of people with epilepsy and their families. Eisai is proud to market currently more epilepsy products in EMEA than any other company.

Epilepsy is one of the most common neurological conditions in the world. There are an estimated six million people who live with epilepsy in Europe, and an estimated 50 million people with the condition 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.
