ONTOZRY® (Cenobamate) Receives European Commission Approval for the Treatment of Drug-Resistant Focal-Onset Seizures in Adults

PANGYO, GYEONGGI PROVINCE, Korea, March 30, 2021 /PRNewswire/ -- SK Biopharmaceuticals, Co., Ltd., a global innovative pharmaceutical company, announced today that cenobamate received marketing authorization from the European Commission (EC) under the brand name ONTOZRY^® for the adjunctive treatment of focal-onset seizures with or without secondary generalization in adult patients who have not been adequately controlled despite a history of treatment with at least two anti-epileptic medicinal products.

The marketing authorization, granted to Arvelle Therapeutics, recently acquired by Angelini Pharma, will be valid in all European Union Member States as well as Iceland, Norway and Liechtenstein. Angelini Pharma plans to launch ONTOZRY^® in the European Union and other countries in the European Economic Area (Switzerland and the United Kingdom). SK Biopharmaceuticals, which discovered and developed cenobamate, will collaborate with Angelini Pharma to launch ONTOZRY^® in Europe. Cenobamate was approved by the U.S. Food and Drug Administration (FDA) for the treatment of partial-onset (focal-onset) seizures in adults in 2019 and is commercially available in the U.S. under the brand name XCOPRI^® (cenobamate tablets) CV.

"The approval by the European Commission is another major milestone in our efforts to increase access to cenobamate and to support patients with a much-needed new treatment option," said Jeong Woo Cho, PhD, President and CEO of SK Biopharmaceuticals and SK life science. "As a fully-integrated global pharmaceutical company, we are committed to discovering, developing and delivering new treatment options for epilepsy and other central nervous system disorders to people around the world."

Epilepsy is one of the most common neurological diseases in the world, and an estimated six million people in Europe live with seizures.¹ Among adult patients with focal-onset seizures, approximately 40% continue to experience seizures after treatment with two anti-seizure medications (ASMs).²

The approval was based on results from a global clinical trial program conducted by SK life science, the U.S. subsidiary of SK Biopharmaceuticals. The clinical trial program includes two randomized, double-blind, placebo-controlled studies and a large, multi-center, open-label safety study. These three studies enrolled more than 1,900 adults with uncontrolled focal-onset seizures.

"ONTOZRY will be a welcome new treatment option in Europe for adults who have not yet been able to control their focal-onset seizures with available treatments. Treatment-resistant epilepsy has a devastating effect on these patients and their families, and we are proud to help address this urgent health challenge," said Pierluigi Antonelli, CEO of Angelini Pharma. "Angelini Pharma looks forward to bringing ONTOZRY to these patients across Europe and will continue to help address the needs of patients with central nervous system disorders through our innovative product portfolio and pipeline."

About Cenobamate
Cenobamate was discovered and developed by SK Biopharmaceuticals and SK life science. While the precise mechanism by which cenobamate exerts its therapeutic effect is unknown, it is believed to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the γ-aminobutyric acid (GABA_A) ion channel.

Cenobamate is approved in the United States as an anti-seizure medication (ASM) for the treatment of partial-onset seizures in adults, and is available under the brand name XCOPRI^® (cenobamate tablets) CV.

Cenobamate was approved in the EU under the brand name ONTOZRY^® for the adjunctive treatment of focal-onset (partial-onset) seizures with or without secondary generalization in adult patients with epilepsy who have not been adequately controlled despite a history of treatment with at least two anti-epileptic medicinal products. SK Biopharmaceuticals entered an exclusive licensing agreement with Arvelle Therapeutics to develop and commercialize cenobamate in Europe in early 2019. Angelini Pharma, which recently announced a definitive merger agreement to acquire Arvelle Therapeutics, plans to launch cenobamate in the European Union and other countries in the European Economic Area (Switzerland and the United Kingdom).

SK Biopharmaceuticals also has an exclusive licensing agreement with Ono Pharmaceutical to develop and commercialize cenobamate in Japan.

IMPORTANT SAFETY INFORMATION AND INDICATION FOR ONTOZRY IN THE EUROPEAN UNION
ONTOZRY^® has been approved in the EU for the adjunctive treatment of focal-onset seizures with or without secondary generalization in adult patients with epilepsy who have not been adequately controlled despite a history of treatment with at least 2 anti-epileptic medicinal products. The recommended starting dose of cenobamate is 12.5 mg per day, titrated gradually to the recommended target dose of 200 mg per day. Based on clinical response, dose may be increased to a maximum of 400 mg per day.

Cenobamate is contraindicated in patients with hypersensitivity to the active substance or to any of the excipients, and patients with familial Short-QT syndrome.

According to the cenobamate EU Risk Management Plan, the occurrence of drug rash with eosinophilia and systemic symptoms (DRESS) has been recognized as an important identified risk of the drug. Important potential risks are hypersensitivity, suicidality (class effect), QT shortening, and reproductive / embryofoetal toxicity.

In clinical trials, the most commonly reported adverse reactions were somnolence, dizziness, fatigue and headache. The approved Product Information of ONTOZRY^® includes the routine risk minimisation measures for reducing safety risks in patients treated with the medicinal product.

You can enroll in this registry by calling 1-888-233-2334 or go to www.aedpregnancyregistry.org.  

Talk to your health care provider if you are breastfeeding or plan to breastfeed. It is not known if XCOPRI passes into breastmilk. Talk to your healthcare provider about the best way to feed your baby while taking XCOPRI.

COMMON SIDE EFFECTS:

The most common side effects in patients taking XCOPRI include dizziness, sleepiness, headache, double vision, and feeling tired.

These are not all the possible side effects of XCOPRI. Tell your healthcare provider if you have any side effect that bothers you or that does not go away.

About Epilepsy  
Epilepsy is the fourth most common neurological disorder. There are approximately 3.4 million people living with epilepsy in the United States, with 150,000 new cases each year in the country.³ There are an estimated six million people in Europe with epilepsy.¹ Epilepsy is characterized by recurrent, unprovoked seizures. The seizures in epilepsy may be related to a brain injury or a family tendency, but often the cause is completely unknown. Having seizures and epilepsy can affect one's safety, relationships, work, driving, and much more.⁴ People with epilepsy are at risk for accidents and other health complications, including falling, drowning, depression and sudden unexplained death in epilepsy (SUDEP).^4,5 Despite the availability of many antiepileptic therapies, almost 40 percent of people with epilepsy are not able to achieve seizure freedom, meaning they have epilepsy that remains uncontrolled.²
