Brief Summary
|
This is a Randomized, Multicentre, Open Label, Active Controlled, Parallel Group, Phase III Clinical Study to Evaluate the Efficacy and Safety of Cenobamate Tablets in Comparison with Eslicarbazepine acetate Tablets in Adult Patients suffering from Focal Onset Seizures. Subjects randomized to the test arm will receive Cenobamate tablets once daily for 18 weeks. Subjects will receive Cenobamate 12.5 mg tablets once daily for the first 2 weeks. The dose will be up titrated to 25 mg once daily on week 3, 50 mg once daily on week 5, 100 mg once daily on week 7 and 150 mg once daily on week 9. From week 11 to 16 (Day 77 to 112) Subjects will receive 200 mg Cenobamate tablets once daily (maintenance dose). Following this period, the dose will be tapered off. On week 17 the dose will get down-titrated to 100 mg once daily and after 4 days the dose will get reduced to 50 mg once daily. On week 18 the dose will get down-titrated to 25 mg once daily and after 4 days the dose will get reduced to 12.5 mg once daily and then stopped. Subjects randomized to the comparator arm will receive Eslicarbazepine 400 mg tablets once daily for the first 5 weeks. From Week 6 to Week 10 Subjects will receive Eslicarbazepine 600 mg tablets once daily. From Week 11 to 18 (Day 77 to 126) Subjects will receive the maintenance dose of 800 mg Eslicarbazepine tablets once daily.The total study duration is approximately 23 weeks (1 week screening period, 4 weeks run-in period, 16 weeks treatment period and 2 weeks tapering period |
