SK Biopharmaceuticals, announced that its European partner Angelini Pharma, has launched cenobamate in France. Cenobamate – under the brand name ONTOZRY – has been commercialized in five major European countries such as Germany, the UK, Italy, Spain, and France, accounting for about 73% of the total value of the continent's epilepsy market. It is also available in 10 other key European markets, including Switzerland and Belgium.

Cenobamate was approved by the European Commission (EC) in March 2021 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. Following the EC's marketing authorization for cenobamate, Angelini Pharma launched the anti-seizure medication in Germany, Europe's largest pharmaceutical market, in June 2021, and launched in the UK, Europe's largest epilepsy market, in November 2021, following the Medicines and Healthcare products Regulatory Agency's approval. Cenobamate was discovered by SK Biopharmaceuticals and its U.S. subsidiary SK Life Science, which have forged a partnership with Angelini Pharma for the European markets.
