Epilepsy | Open-label, Randomized, Active-controlled Study of LEV Used as Monotherapy in Patients With Partial-Onset Seizures

Epilepsy research study

What is the primary objective of this study?

To demonstrate the non-inferiority of Levetiracetam (1000 mg/day) versus Carbamazepine Immediate-Release (400 mg/day) used as monotherapy for at least 6 months in a Chinese population with newly or recently diagnosed Epilepsy who are experiencing Partial-Onset Seizures (POS).
