E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of LEV used as monotherapy,
with efficacy measured as 6-month seizure freedom at the last evaluated dose in the LEV 1000 mg/day to 2000 mg/day group, in newly or recently diagnosed epilepsy subjects.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are the following:
- To evaluate the 1-year efficacy of LEV used as monotherapy at the last evaluated dose in the LEV 1000 mg/day to 2000 mg/day group
- To evaluate the efficacy of LEV used as monotherapy in subjects in the LEV 3000 mg/day group
- To evaluate the long-term safety of LEV used as monotherapy
|

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Subject is male or female and aged ≥ 16 years at Visit 1
