Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations

The study was conducted at 160 sites in the United States of America (USA), Canada, Europe, and Australia.The maximum duration of a subject’s trial participation is 30 weeks.

The Participant Flow refers to the Safety Set (SS) population which consists of all patients who received at least one dose of study medication.


Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects were randomized 3:1 to one of two therapeutic doses of Lacosamide, 400 mg/day or 300 mg/day, to ensure a study design comparable to the historical control.
