Inclusion criteria
Inclusion criteria: Inclusion Criteria for Subjects who have Participated in Studies A0081041, A0081042, or A0081105 - Subject eligibility should be reviewed and documented by an appropriately qualified member of investigator’s study team before subjects are included in study. Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the study: 1. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of Study A0081106. When there are 2 parents or 2 legally acceptable representatives, consent should be obtained from both of the child’s parents/legal representatives if present at the meeting where the informed consent document is signed. Subject to local regulations whenever the minor is able to give assent, the minor’s assent must be obtained. 2. Subjects and/or parents/legally acceptable representative who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. 3. Male and female subjects who have participated in and completed, or participated in Studies A0081041, A0081042, or A0081105. For subjects who have participated in, but did not complete Studies A0081041, A0081042, or A0081105, eligibility for Study A0081106 will be reviewed with a member of the Pfizer study team to determine further eligibility. Subjects are required to have completed a minimum of 4 weeks of double blind treatment in Studies A0081041 or A0081105 to be considered potentially eligible for Study A0081106. 4. Male and female epilepsy subjects who have participated in either Study A0081041 or Study A0081042, 1 month to 16 years of age inclusive on the date of the Screening Visit with diagnosis of epilepsy with seizures classified as simple partial, complex partial or partial becoming secondarily generalized, according to the International League Against Epilepsy (ILAE 2010) Diagnosis must be established by: Subject’s history (eg, description of seizures excluding confounding disorders such as pseudoseizures, syncopes etc) family history and neurological exam; Subjects must have had a contrast enhanced computed tomography (CT) or magnetic resonance imaging (MRI) scan of the brain and electroencephalogram (EEG) testing prior to Study A0081041 or Study A0081042. Results must have been consistent with the diagnosis of focal onset epilepsy and must have demonstrated that no abnormality was likely to be progressive. 5. Male and female subjects 5 65 years of age who have participated in Study A0081105 with a diagnosis of epilepsy (ILAE 2010) with PGTC seizures and who continue to satisfy seizure related inclusion criteria for that study. Subjects who have participated in study A0081105 and who reach the age limit of 66 years of age will still be allowed to enter this study. 6. Currently receiving a stable dose of 1 to 3 antiepileptic drugs at Visit 1. Benzodiazepine medication used on a regular basis will be considered 1 of the concurrent antiepileptic treatments. The vagus nerve stimulator (VNS) is allowed and considered 1 of the 3 antiepileptic treatments. 7. A 12 lead ECG at (the last visit of Studies A0081041, A0081042, A0081105) without significant abnormal findings. For Directly Enrolling Subjects (who have not participated in either Studies A0081041 or A0081042) In order for Direct Enrolling Subjects to be eligible, all of the following incl
Exclusion criteria
Exclusion criteria: 1. Lennox Gastaut syndrome, Infantile Spasms, Absence seizures for Direct Enrolling Subjects, BECT and Dravet syndrome. A current diagnosis of febrile seizures, any febrile seizures within 1 year of screening, or seizures related to an ongoing acute medical illness. Prior history of febrile seizures may be allowed on a case by case basis following consultation with study clinician. Any febrile seizures within 1 year of screening. 2. Status epilepticus within 1 year prior to Visit 1 of this study. 3. Seizures related to drugs, alcohol, or acute medical illness. 4. Progressive structural CNS lesion or a progressive encephalopathy. Progressive inborn errors of metabolism. 5. Known or suspected chronic hematologic, hepatic or renal disease (AST and ALT above 3 times the upper limit of normal; or bilirubin, BUN, or creatinine above 2 times the upper limit of normal within the previous 6 months for infants, children and adolescents aged 6 months or more, or at any postnatal period for infants younger than 6 months). Estimated creatinine clearance (CLcr) <60 mL/min for subjects =17 yr and <80 mL/min/1.73m2 (using age appropriate equations) for subjects <17 years of age. 6. Other severe acute or chronic medical (eg, genetic or chromosomal syndromes) or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of results and, in the judgment of the investigator or the sponsor, would make the subject inappropriate for entry into this study. 7. Pregnant or nursing females (females who are menarchal must have a negative urine pregnancy test); menarchal females of childbearing potential who are unwilling or unable to use an acceptable method of contraception, as outlined in the protocol, until completion of follow-up procedures. 8. Taking any non antiepileptic (non AED) medication that could alter the effectiveness of the subject’s medication, response, seizure frequency or characteristics. Medications for Attention Deficit/Hyperactivity Disorder and other behavioral changes will be permitted. A ketogenic diet will also be allowed given that the diet is adhered to for the duration of the study. Note: changes in the dose, regimen and type of these medications during study participation may be allowed upon discussion with the study clinician. Continued participation of the subject will be evaluated and decided on a case by case basis. 9. Taking or have taken any other investigational drug (aside from participation in Studies A0081041, A0081042 or A0081105) within the last 30 days prior to screening. 10. The concomitant use of gabapentin, felbamate and vigabatrin is prohibited. 11. Use of cocaine, phencyclidine (PCP), or other illegal or illicit drugs is prohibited.

Subjects not reasonably expected to complete the study. 14. Any subjects considered at risk of suicidal behavior based upon the C-SSRS Lifetime (subjects =6 years of age) or CBCL (subjects <6 years of age) or responses obtained during the MINI-KID. A subject should be excluded or a risk assessment should be done by a qualified mental healt
