Részletes leírás
This was a phase III, 2-part multicenter study. Part I was an 26-week parallel-group, randomized, placebo-controlled design consisting of an 8 week baseline period, a 2 week double-blinded titration period, 12 week maintenance period, and a 4 week tapering-off period. After completing the baseline period, patients were randomized in a 1:1:1 ratio to 1 of the 2 ESL daily dose levels (1200 or 800 mg) or placebo.
Part II was a 1-year open-label extension for patients who had completed Part I. Starting at 800 mg/day, the dosage could be titrated at 400 mg intervals down to a minimum of 400 mg/day or up to a maximum of 1200 mg/day. Patients who completed Part II could participate in a study extension and continue treatment with ESL until marketing authorization is obtained or clinical development is discontinued, with visits scheduled at the discretion of the investigator but at least every 6 months.
Results from Part I & II were presented in two separate reports.

Exclusion Criteria:
- only simple partial seizures with no motor symptomatology (classified as A2-4 according to the International Classification of Epileptic Seizures) that are not video-EEG documented
- primarily generalised epilepsy
- known rapid progressive neurological disorder; history of status epilepticus or cluster seizures (i.e., 3 or more seizures within 30 minutes) within the 3 months prior to screening
- seizures of psychogenic origin within the last 2 years
- history of schizophrenia or suicide attempt
- currently on or with exposure to felbamate or oxcarbazepine more within one month of screening
- using benzodiazepines on more than on an occasional basis (except when used chronically as AED)
- previous use of ESL or participation in a clinical study with ESL
- known hypersensitivity to carbamazepine, oxcarbazepine or chemically related substances

Seizure Frequency
Időkeret: 12 weeks
|
The primary efficacy endpoint is the natural log transformation of the seizure frequency per 4 weeks.
The primary efficacy analysis was based on results for the ITT population during the 12-week maintenance period.
Seizure frequency was compared between each active treatment group and the placebo group using an ANCOVA model with treatment as a factor and seizure frequency as a covariate

PART II: Nº of Treatment-Emergent Adverse Events (TEAE)
Időkeret: 1-year
|
The primary objective for Part II of the study was to evaluate the safety and tolerability of eslicarbazepine acetate (ESL, BIA 2-093) at doses titrated to an efficacy or safety endpoint over a 1-year open-label period.
Safety assessments were based primarily on AEs (Number of participants with at least one treatment-emergent adverse events are reported); assessment of AEs was based on treatment relatedness, action taken on study drug, outcome, and causality.
