Cenobamate is a newly-FDA and EMA approved drug used to treat -focal-onset seizures in adult patients.

The aim of the current study is to analyse retrospectively the overall effectiveness and tolerability of cenobamate from real-world data collected in patients who partecipated in the Early Access Program (EAP) and were treated with cenobamate as adjunctive ASM.

Cenobamate is a new approved drug used to treat -focal-onset seizures in adult patients. This novel tetrazole-derived carbamate seems to act primarily by two mechanisms that are commonly associated with epilepsy: cenobamate acts as a positive allosteric modulator of the GABAA ion channels and is effective in reducing repetitive neuronal firing by inhibition of voltage-gated sodium channels, although the complete mechanism of action is currently unknown.

In clinical trials, cenobamate showed also low toxicity and adverse drug reaction profile.

In European Union (EU), cenobamate received the marketing authorisation, valid throughout the EU, in March 2021. Starting from September 2020 an EAP was initiated with cenobamate as adjunctive ASM in several EU Countries such as Germany, France, and UK.

Real-world data are of importance to understand and confirm the efficacy and safety profile of drugs outside of the clinical trial setting. The aim of the current study is to analyse the overall effectiveness and tolerability of cenobamate from real-world data in a large series of patients treated with cenobamate as adjunctive ASM.

As a consequence, a retrospective collection and analysis of the data of the patients who participated in the EAP, according to the authorization received from the local regulatory or ethic authorities, was conducted.

Inclusion Criteria:

• Data from adult patients diagnosed with epilepsy with FOS participating in the EAP with cenobamate as adjunctive treatment, according to the authorization received from the local regulatory or ethic authorities will be collected and analyzed.
• Available data will be collected after obtaining consent from patient/legal representative to the processing of personal data according to the General Data Protection Regulation (GDPR) and applicable local regulation

Exclusion Criteria:

• Patient enrolled in other clinical trial during the EAP.
• Patient aged less than 18 years old.
• Patient with specific syndrome (e.g. LGS and Dravet)

The study population includes adult patients suffering from epilepsy with FOS who have been treated with cenobamate as adjunctive Anti-seizure medication (ASM) during the EAP in Germany, France and UK.
