Who can join

Age: 4 and older, up to 17. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject is male or female, 4 to < 18 y at enrollment, and weighs at least 11 kg at Screening and on the first day of ESL dosing.
• The informed consent must be signed by the parent or legal guardian, and, when appropriate and/or required by state or local law, minor subjects must give written informed assent prior to participation in the study. All subjects in the United States (US) must have a parent or legal guardian, sign a Health Insurance Portability and Accountability Act (HIPAA) form.
• Confirmed diagnosis of epilepsy with partial onset seizures as defined in the Classification of Seizures of the International League Against Epilepsy:
• Epilepsy with partial onset seizures with observable motor component, or complex partial seizures, with or without secondary generalization
• Documented EEG recording without generalized epileptiform abnormalities and with demonstrated focal abnormalities (done within 5 years prior to screening)
• Documented magnetic resonance imaging (MRI) scan conducted within 5 years (older scans may be acceptable with consent of Medical Monitor) prior to screening, showing either normal results or static focal abnormalities.
• Documented seizure frequency of at least 6 seizures per month prior to screening as reported by a caregiver and documented in subject's seizure history. Note: Retrospective reporting of seizure frequency does not require diary documentation.
• Stable treatment with 1 to 3 AEDs (excluding carbamazepine and oxcarbazepine) for ≥ 2 weeks prior to screening and at least 4 weeks prior to the first ESL dose. Vagal nerve stimulation (if present) does not count as an AED.
• Subject and/or caregiver are willing and able to complete a daily seizure diary for the duration of the study and comply with study procedures.
• A female subject is eligible to enter and participate in the study if she is of:
• Non-childbearing potential because she is premenarchal (as assessed by physical examination) and < 7 y; or
• Non-childbearing potential because she is premenarchal (as assessed by physical examination), ≥ 7 y, and has a negative urine pregnancy test at screening; or
• Childbearing potential; has a negative serum pregnancy test at screening and agrees to satisfy one of the following requirements:
• Complete abstinence from intercourse as a component of a habitually abstinent lifestyle; a minimum of 4 weeks prior to administration of the first dose of study drug, throughout the treatment period, and for a minimum of 8 weeks after completion or premature discontinuation from the study drug (abstinence must be part of an established abstinent lifestyle), and agrees to use a double-barrier method if she becomes sexually active; or
• Established use of acceptable methods of contraception; a minimum of 4 weeks prior to administration of the first dose of study drug, throughout the treatment period, and for a minimum of 8 weeks after completion or premature discontinuation from the study drug. Acceptable methods of birth control are those with established failure rates of < 1%per year and include:
• Double barrier birth control, which is limited to a condom plus spermicide or a condom plus diaphragm.
• Intrauterine device (IUD). Note: Female subjects who are ≥ 7 y and premenarchal will not routinely undergo serum pregnancy tests and will only be administered a urine pregnancy test. A positive urine pregnancy test should be confirmed by a serum test in these subjects regardless of weight. Female subjects who are < 7 y will not undergo a serum or a urine pregnancy test.
• Note: ESL may interfere with the action of hormonal contraceptive and therefore hormonal contraceptives are not sufficient for this protocol.
• Males must be willing to remain sexually abstinent (consistent with lifestyle) or use an effective method of birth control (eg, male using condom and female using diaphragm, contraceptive sponge, spermicide, contraceptive pill, or intrauterine device) from signing informed consent to at least 7 days after the last dose of study drug has been taken.
• Stable environment with caregiver who can assist in completion of seizure diary and other study assessments, if needed.
• Subject and/or caregiver must read and write and possess an educational level and degree of understanding of the local language at a level sufficient to complete study related assessments or communicate suitably with the Investigator and study coordinator. For subjects who do not meet this criterion, a caregiver must be able to meet this requirement on the subject's behalf.
• Inclusion Criteria for Monotherapy Conversion Subjects (at or after Month 6)
• Subject is < 18 years-old at time of taper/conversion.
• Subject has a satisfactory response to ESL at ≥ 6months of treatment in present study (based on tolerability and reduction in seizures, as determined by the Investigator).
• Subject is receiving 1 or 2 background AEDs (not including benzodiazepine or barbiturate).

You may not qualify if…

• Subject has had prior exposure to or previously participated in a clinical study with ESL.
• Subject has a history of allergic reaction to oxcarbazepine or carbamazepine, or a history of serious allergic reaction (Stevens Johnson syndrome, Drug Reaction with Eosinophilia and Systemic Symptoms [DRESS] or similar) to any AED, or a history of serious allergic reactions to other medications.
• Subject has had an EEG showing generalized discharges.
• Subject has had any of the following seizure types at any time: myoclonic, absence, or atonic.
• Subject has Lennox-Gastaut Syndrome or other secondary generalized epilepsy (including inborn errors of metabolism), or Benign Rolandic Epilepsy.
• Subject has a current diagnosis or a history of psychogenic seizures.
• Subject has current seizures related to an acute medical illness.
• Subject has purely subjective seizures.
• Subject has had status epilepticus while taking any seizure medicine in the 3 years prior to screening.
• Subject should not have had febrile illness ≤ 2 weeks prior to screening.
• Subject is currently taking more than 3 AEDs or is taking carbamazepine or oxcarbazepine.
• Subject is taking any protocol-prohibited medication within 4 weeks of first ESL dose.
• Subject has any confounding factor such as pseudoseizures or syncope.
• Subject has a known progressive structural CNS lesion(s) or progressive encephalopathy.
• Subject (≥ 6 y) has an active suicidal plan or intent (in the Investigator's opinion) in the past 4 weeks prior to screening.
• Subject has a history of suicide attempt in the last 2 years prior to screening.
• Subject is at imminent risk of suicidal or homicidal action (in the Investigator's opinion).
• Subjects who meet the Diagnostic and Statistical Manual of Mental Disorders, 5th edition text revision (DSM-V-TR) defined criteria for major depressive episode (MDE) within the last 6 months. Subjects with mild, chronic depression without recent hospitalization who are being maintained on a stable dose of a single antidepressant are acceptable.
• Subject has a significant psychiatric disorder or history of recurrent episodes of severe depression requiring pharmacologic treatment or hospitalization within 2 years prior to screening.
• Subject has a history of alcohol or substance abuse within 2 years prior to screening for study participation, or subjects currently using alcohol, drugs of abuse, or any prescribed or over-the-counter medication in a manner, which, in the opinion of the Investigator, indicates abuse. Subjects who are regular users of medical marijuana are excluded; use during participation is prohibited.
• Subject has a positive urine drug screen (UDS) at screening. Note: Subjects with a positive drug screen for amphetamines, opiates, or benzodiazepines, who have a prescribed medication for at least 4 weeks prior to screening, may be eligible to participate in the study upon approval from the Medical Monitor.
• Subject has a major medical illness other than epilepsy that would prevent safe participation in this study, at the discretion of the Investigator, such as (but not limited to) chronic liver or kidney impairment.
• Subject has a disorder or history of a condition that may interfere with drug absorption, distribution, metabolism, or excretion (eg, malabsorption, gastrointestinal surgery, clinically significant abnormality of the hepatic or renal system). Note: Active medical conditions that are minor or well-controlled are not exclusionary if they do not affect risk to the subject or the study results. In cases in which the impact of the condition upon risk to the subject or study results is unclear, the Medical Monitor should be consulted.
• Subject has a history or presence of abnormal ECG, which in the Investigator's opinion is clinically significant or QTcB of \~ 450 msec per screening central over read ECG.
• Subject is known to have tested seropositive for the human immunodeficiency virus (HIV).
