Efficacy and Safety of Levetiracetam in Partial Seizures Control, With or Without Secondary Generalization (Mozart)
October 27, 2016 updated by: Ache Laboratorios Farmaceuticos S.A.
A Double-blind, Phase III, Multicenter, Randomized, Placebo-controlled Study to Evaluate the Efficacy and Safety of Levetiracetam as Adjunctive Therapy, in Partial Seizures Control Associated With Refractory Focal Epilepsy
The purpose of this study is to determine whether levetiracetam as adjunctive therapy is effective in the treatment of partial seizures, with or without secondary generalization, associated with refractory focal epilepsy.

- Patient with onset of seizures for at least 02 years preceding the screening visit;
Presence at least 12 partial seizures during the 03 months preceding the screening visit (04 seizures per month);
- Only seizures that generate motor manifestation will be recorded in this study.
- Absence of brain injury progressive or expansive, previously documented by CT scan, MRI or other imaging test applicable (in the last 05 years;
- Patient with electroencephalogram performed up to 02 years before this visit;
Subject with stable regimen (minimum of 01 month) from one to three antiepileptic drugs.

Exclusion Criteria:
Patients with:
- Seizures of non epileptic origin;
- Pseudoseizures;
- Seizures occurring in clustered patterns (03 or more seizures in 30 minutes), in the 03 months preceding the screening visit (V1);
- History of status epilepticus while taking antiepileptic drugs during the 03 months that preceding the screening visit (V1).
- Epileptic syndromes that occurs with cognitive deficits or secondary epilepsy evolving from some brain disease;
- History of schizophrenia or suicide attempt;
- Patients with psychiatric ill ongoing;
