The study was designed to include 3 parts; only the first part is described in this report. Part I of the study was an international, randomized, placebo-controlled, double-blind, parallel group, mult...

Eligibility Criteria

Inclusion

  • Inclusion Criteria
  • At V1 (screening), patient must be/have:
  • Written informed consent signed by patient.
  • Aged 16 years or more (patients under 18 years of age require parental/legal representative consent). In North America as well as in other participating countries, when appropriate and/or required by state or local law, minor patients must give written informed assent prior to participation in the study.
  • A documented diagnosis of epilepsy since at least 12 months prior to screening.
  • At least 4 partial-onset seizures (including subtypes of simple partial, complex partial and partial seizures evolving to secondarily generalised) on the 4 weeks prior to screening.
  • Currently treated with 1 or 2 AEDs (any except OXC), in a stable dose regimen during at least 1 month prior to screening. Patients using vigabatrin should have been on this medication for at least 1 year with no deficit in visual field identified (a confirmatory test should be available within 1 month before study entry). The device for VNS should be implanted at least 6 months before screening; parameters need to be stable for at least 1 month prior to screening (VNS will not be counted as concomitant AED).
  • Excepting epilepsy, patient is judged to be in general good health based on medical history, physical examination findings, and clinical laboratory test results.
  • Post-menopausal or otherwise incapable of becoming pregnant by reason of surgery or tubal ligation. In case of women of childbearing potential (WOCBP), patient must present a serum beta-human chorionic gonadotropin (B-hCG) test consistent with a non gravid state and agree to remain abstinent or use reliable contraception (hormonal contraception should be combined with a barrier method) beginning at screening and continuing at least to the PSV.
  • At V2 (randomisation), patient must have:
  • At least 8 partial-onset seizures during baseline with at least 3 partial-onset seizures in each 4-week section of the 8-week baseline period prior to randomisation (documented in a diary) and no seizure-free interval exceeding 28 consecutive days.
  • In case of WOCBP, patient must present a urine B-hCG test consistent with a non gravid state.
  • Diaries satisfactorily completed by the patient or his/her caregiver.
  • Satisfactorily complied with the study requirements during the baseline period (including no changes in concomitant AED therapy should have occurred in the baseline period).
  • Exclusion Criteria
  • At V1 (screening), patients must not be/have:
  • Only simple partial seizures with no motor symptomatology (classified as A2 4 according to the International Classification of Epileptic Seizures).
  • Primarily generalised seizures.
  • Known progressive neurological disorders (progressive brain disease; epilepsy secondary to progressive cerebral lesion).
  • Occurrence of seizures too close to count accurately.
  • 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 non-epileptic origin.
  • Seizures of psychogenic origin within the last 2 years.
  • Major psychiatric disorders.
  • Documented diagnosis of schizophrenia with accompanying documented history of at least 1 acute psychosis episode within the last 2 years) or history of suicide attempt.
  • Currently treated with OXC.
  • Using benzodiazepines on more than an occasional basis (defined as more than 2 times per week), except when used chronically as AED.
  • Known exposure to Eslicarbazepine acetate from previous study.
  • o Previous use of Eslicarbazepine acetate or participation in a clinical study with Eslicarbazepine acetate (patients not exposed to Eslicarbazepine acetate \[e.g., screen failed\] are allowed).
  • Known hypersensitivity to carboxamide derivatives.
  • History of abuse of alcohol, drugs or medications within the last 2 years.
  • Uncontrolled cardiac, renal, hepatic, endocrine, gastrointestinal, metabolic, haematological or oncology disorder.
  • Second or third-degree atrioventricular blockade not corrected with a pacemaker.
  • Relevant clinical laboratory abnormalities (e.g., sodium \<130 mmol/L, alanine or aspartate transaminases \>2.0 times the upper limit of the normal, white blood cell \[WBC\] count \<3,000 cells/mm3) or for patients of Asian ancestry, positive HLA B\*1502 test.
  • Estimated creatinine clearance \<60 mL/min \[men: (140-age) x weight/serum creatinine x 72; women: (0.85) (140-age) x weight/serum creatinine x 72. Age in years, weight in kg, and serum creatinine in mg/dL\].
  • Pregnant or nursing.
  • Participation in other drug clinical trial within the last 2 months or received an investigational drug within 5 half-lives of this other product, whichever is longer. Patient(s) who are known to have not taken any doses of study drug(s) in earlier study(ies) (e.g. screen-failures) are allowed without any time limitation.
  • Not ensured capability to perform the trial.
  • Any other condition or circumstance that, in the opinion of the Investigator, may compromise the patient's ability to comply with the study protocol.
  • Currently treated with VNS, but implanted \<6 months before screening or parameters not stable for at least 1 month prior to screening.
  • At V2 (randomisation), patients must not be/have:
  • Inadequate compliance to concomitant AEDs during the 8-week baseline period or to screening exclusion criteria.
  • Inadequate completion of the study diary.
  • Any other condition or circumstance that, in the opinion of the Investigator, may compromise the patient's ability to comply with the study protocol.
