| 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.3 | Principal inclusion criteria  | 
- Subject is male or female and aged ≥ 16 years at Visit 1
 - Subjects with newly or recently diagnosed Epilepsy having experienced unprovoked Partial Seizures (IA, IB, IC), that are classifiable according to the International League Against Epilepsy (ILAE) classification of Epileptic Seizures
 - Subjects with at least 2 unprovoked seizures separated by a minimum of 48 hours in the year prior to Visit 1, of which, at least 1 unprovoked seizure occurred in the 3 months prior to Visit 1
