Cenobamate use results in unprecedented seizure freedom rates for patients 1

PARIS–(BUSINESS WIRE)–Angelini Pharma, international pharmaceutical company part of the privately held Italian Angelini Group, today announced that ONTOZRY® (cenobamate) is now available in France and Belgium for the adjunctive treatment of focal-onset seizures with or without secondary generalization in adults patients who have not been adequately controlled despite an history of treatment with at least two anti-epileptic medicinal products. The product obtained approval from The European Medicines Agency in March ’21.2

Approximately 40% of adult patients with focal epilepsy have inadequate control of seizures even after treatment with two anti-seizure medications (ASMs).3

Safety and efficacy of this product has been evaluated in three key trials involving over 1,900 patients.1,4,5 The pivotal trial (study 017) published in The Lancet Neurology1 is a multicenter, double-blind, randomized, placebo-controlled trial has demonstrated that cenobamate at doses of 100 mg, 200 mg, and 400 mg/day significantly improved seizure control versus placebo for adult patients with focal-onset seizures taking 1-3 ASMs. 1

The product demonstrated significantly higher responder rates (percentage of patients achieving ≥50% reduction in seizures) across all doses during the 12-week maintenance phase compared to placebo. The responder rates were 40% (p=0.036), 56% (p<0.001), and 64% (p<0.001), for the 100 mg, 200 mg, and 400 mg groups, respectively, compared to 25% in the placebo arm. Furthermore, 4% (not significant), 11% (p=0.002), and 21% (p<0.001), of patients treated with this product 100 mg, 200 mg and 400 mg per day, respectively, reported zero focal-onset seizures (100% seizure freedom) compared with only 1% of placebo treated patients during the maintenance phase.1

The global disease burden of epilepsy is high.6,7 A diagnosis of epilepsy confers significant disability on the individual, including physical, psychological, and social issues that negatively impact self-esteem, family environment, relationships, leisure and working life .6,8

In addition, people with epilepsy whose seizures are poorly controlled have higher morbidity and mortality rates, and often experience comorbid illnesses, social stigmatization, and an impaired quality of life.8,9

The product, which was developed by SK Biopharmaceuticals Co., Ltd. and SK Life science, Inc. that have partnered with Angelini Pharma for the European market, marks a therapeutic breakthrough in managing the disease, and bringing hope to patients living with epilepsy.11

About Cenobamate

Cenobamate was discovered and developed by SK Biopharmaceuticals and SK life science and is an FDA and EMA-approved ASM for the treatment of partial-onset seizures in adults (also known as focal-onset seizures). Cenobamate is commercially available in the US under the trademark XCOPRI®.12

Cenobamate is a novel small molecule that provides a dual, complementary mechanism of action aimed at treatment of seizures. Cenobamate at clinically relevant concentrations, acts both as a positive allosteric modulator of GABAA receptors at a non-benzodiazepine binding site and preferentially blocks the persistent sodium current.13 The dual mechanism of action of cenobamate suggests that it has the potential to both prevent seizure initiation and limit seizure spread.14

Long-term data of cenobamate is being studied in the open-label extensions of the double-blind placebo control trials as well as the open-label safety study in adults with uncontrolled focal-onset seizures.5 Additionally, the product is being assessed in an ongoing randomized, double-blind, placebo-controlled trial evaluating its safety and efficacy as adjunctive therapy in patients with primary generalized tonic-clonic seizures. (NCT03678753)18

Cenobamate has recently gained recognition by healthcare regulatory bodies in the United Kingdom and Germany given its potential use in treatment resistant focal-onset seizures in epilepsy. The drug is available in Europe including Germany, Austria, Hungary, Sweden, Denmark, Norway, Finland Netherlands, Italy, Slovakia Spain, Belgium, France, Northern Ireland, as well as in UK and Switzerland, under the trademark ONTOZRY®.
