Levetiracetam Versus Standard Antiepileptic Drugs (Carbamazepine and Valproate) Used as Monotherapy in Patients With Newly Diagnosed Epilepsy

A Therapeutic Confirmatory, Open-label, Multi-center, Randomized 2 Parallel Groups, Community-based Trial Studying the Efficacy and Safety of Levetiracetam (1000 to 3000 mg/Day Oral Tablets 250-500 mg b.i.d.) Compared to Sodium Valproate (1000 to 2000 mg/Day Oral ER Tablets 300-500 mg b.i.d.) and Carbamazepine (600 to 1600 mg/Day Oral CR Tablets 200-400 mg b.i.d.) as Monotherapy in Subjects With Newly Diagnosed Epilepsy.

Brief summary

Study N01175 was to compare overall effectiveness (efficacy and safety) of levetiracetam (LEV) versus the 2 older antiepileptic drugs (AEDs), sodium valproate extended release (VPA-ER) and carbamazepine controlled release (CBZ-CR) in the treatment of subjects with newly diagnosed epilepsy.

Interventions

DRUGLevetiracetam

Daily dose of 1000 to 3000 mg film-coated oral tablets, 250-500 mg twice daily.

Daily dose of 600-1600 mg CR oral tablets, 200 mg and 400 mg twice daily.

DRUGValproate Extended Release

Daily dose of 1000-2000 mg ER oral tablets, 300 mg and 500 mg twice daily.

Inclusion criteria

* Diagnosis of epilepsy (all types of seizures) was made during the past year * Subjects must have had at least two unprovoked seizures in the past 2 years with at least one during the last 6 months * Female subjects without childbearing potential are eligible. Female subjects with childbearing potential are eligible if they use a medically accepted contraceptive method

Exclusion criteria

* Subjects previously allocated to a trial treatment (CBZ, VPA and LEV) used in this trial * Participation in another clinical trial with an investigational drug or device within 12 weeks of the selection visit (V1), or at any time during this trial * Pregnant or lactating women * Presence of known pseudoseizures within the last year * Uncountable seizures (clusters) or history of convulsive status epilepticus * Any disorder or condition that may interfere with the absorption, distribution, metabolisation or excretion of drugs * History of suicide attempt, current suicidal ideation, or other serious psychiatric disorders requiring or having required hospitalization or medication within the previous five years * Presence of progressive cerebral disease, any other progressively degenerative neurological disease, or any cerebral tumors * Presence of a terminal illness or any medical condition that might interfere with the subject's trial participation
