Brief Title ICMJE | A Study to Evaluate XEN1101 as Adjunctive Therapy in Focal Epilepsy | ||||
Official Title ICMJE | A Randomized, Double-blind, Placebo-controlled, Multicenter Study to Evaluate the Safety, Tolerability and Efficacy of XEN1101 as Adjunctive Therapy in Focal-onset Epilepsy, With an Open-label Extension | ||||
Brief Summary | The XEN1101 Phase 2 clinical trial is a randomized, double-blind, placebo-controlled study that will evaluate the clinical efficacy, safety and tolerability of increasing doses of XEN1101 administered as adjunctive treatment in adult patients diagnosed with focal epilepsy, followed by an optional open-label extension (OLE). | ||||
Detailed Description | The XEN1101 Phase 2 clinical trial is designed as a randomized, double-blind, placebo-controlled, multicenter study with an optional open-label extension (OLE) to evaluate the clinical efficacy, safety and tolerability of XEN1101 administered as adjunctive treatment in adult patients aged 18 to 75 years diagnosed with focal epilepsy. Approximately 300 patients will be randomized in a blinded manner to one of three active treatment groups or placebo in a 2:1:1:2 fashion (XEN1101 25 mg : 20 mg : 10 mg : Placebo). After screening, patients will have 8 weeks of baseline to assess frequency of seizures, followed by 8 weeks of treatment and a 6-week post treatment follow-up period. In order to be included in the study, patients must already be treated with a stable dose of 1 to 3 allowable current anti-epileptic drugs for at least one month prior to screening, during baseline, and throughout the double-blind portion (DBP) of the study. During the treatment period, patients will be given XEN1101 or placebo once daily in the evening. An OLE will be available to eligible patients who complete the DBP. All patients will receive a 20 mg daily dose of XEN1101 during this extension period. | ||||
