Inclusion Criteria

-Male or female 16 years of age or older
-Weight of at least 40 kg
-Established diagnosis of partial onset seizures, including simple partial motor, complex partial, or secondarily generalized seizures, for at least 1 year using the International League Against Epilepsy (ILAE) criteria (ILAE 1989) Note: Seizures must be adequately classified as partial onset seizures.
-Must have had a neuroimaging procedure within 5 years, including a computed tomography (CT) scan or magnetic resonance imaging (MRI), that excluded a progressive neurologic disorder; these procedures may be performed within the 56-day baseline period
-History of inadequate response to at least 1 AED, administered at the appropriate dosage(s) and for a sufficient treatment period, based on the judgment of the investigator (subject may be currently treated with this therapy)
-Current treatment with at least 1 and up to 3 AEDs, administered at stable dosage(s) for at least 1 month before screening, and no new AEDs added for the previous 2 months; these AEDs must remain unchanged throughout the pretreatment and double-blind treatment phases (with the exception of dosage reductions of concomitant AEDs because of suspected elevated AED levels or side effects) Note: One-time changes in AED dosages do not represent a change in the daily AED regimen. For example, if the subject took an extra dose of an AED on one day, this would not represent a change in the daily AED regimen. Benzodiazepines received on a continuing basis at stable dosages for 1 month before screening should be considered as concomitant AEDs.
-Females must be: Postmenopausal (for at least 2 years), Surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), Abstinent (at the discretion of the investigator/per local regulations), or if sexually active, be practicing an effective method of birth control
-All females must have a negative serum b human chorionic gonadotropin (b hCG) pregnancy test at screening and a negative urine pregnancy test at the time of randomization on Day 1
-Negative urine drug screen (except for prescription benzodiazepines, prescription barbiturates, or prescription narcotics) at screening
-Negative urine alcohol test at screening
-Willing/able to follow the prohibitions and restrictions specified in this protocol
-Willing/able to complete the subject diaries correctly (subjects or legally acceptable representatives)
-Subjects (or their legally acceptable representatives) must have signed an informed consent form indicating that they understand the purpose of and the procedures required for the study and are willing to participate in this study. Assent is also required of adolescents capable of understanding the nature of the study, as described in the protocol. Note: Subjects with cognitive impairment may be enrolled in this study. The investigator will determine each subject’s capacity to provide informed consent. When cognitive impairment brings a subject’s capacity into question, the investigator will obtain informed consent and assent from the cognitively impaired subject, and consent from the legally acceptable representative(s) in accordance with all applicable local regulations.

Exclusion Criteria

-History of status epilepticus or epilepsia partialis continua in the 6 months before study entry. Status epilepticus is defined as sequential seizures without full recovery of consciousness between seizures, or more than 30 minutes of continuous seizure activity
-Have a generalized epileptic syndrome
-Diagnosis of Lennox-Gastaut Syndrome
-Currently experiencing seizures that cannot be counted accurately, for example, because of the following reasons: Extreme frequency or clustering, Lack of clear onset and cessation between seizures, Lack of informant to provide a seizure count when the subject is unable to independently recall
-Have experienced rates of 100 or more partial onset seizures in any monthly period in the 6 months before study entry
-History of any current or past nonepileptic seizures, including psychogenic seizures
-History of or current serious or medically unstable systemic disease, including clinically apparent liver disease, renal insufficiency, a malignant neoplasm (except treated non-melanoma skin cancer), diabetes requiring insulin, or any disorder which in the judgment of the investigator will place the subject at excessive risk if participating in a controlled study.
-Clinical evidence of cardiac disease, including unstable angina, myocardial infarction, within the past 2 years, uncontrolled heart failure, major arrhythmias, congenital short QT syndrome, or significant shortening or lengthening of the QTcF (Fridericia’s correction) intervals (<330 ms or >500 ms)
-Progressive neurologic disorder, such as a brain tumor, demyelinating disease, and degenerative CNS disease, or active CNS infection
-Current or past (within the past year) major psychotic disorder, such as schizophrenia, bipolar disorder, or other psychotic conditions, recent (within the past 6 months) interictal psychosis, and Major Depressive Disorder with psychotic features
-Exacerbation of Major Depressive Disorder within the past 6 months; antidepressant use is allowed
-History of suicidal or homicidal ideation within the past 2 years, or an episode of suicide attempt or homicide at any time in the past
-History of drug or alcohol abuse within the past year
-Current treatment with vagus nerve stimulation (VNS) for 1 year or less duration
-Planned epilepsy surgery within the next 6 months
-Currently on a ketogenic diet
