入选标准

  • Subjects must meet all of the following criteria to be included in this study:
  • 1. Subjects must have diagnosis of LGS as evidenced by:
  • a. More than one type of generalized seizures, including drop seizures (atonic, tonic, or myoclonic) for at least 6 months before Visit 1
  • b. An EEG reporting diagnostic criteria for LGS at some point in their history (abnormal background activity accompanied by slow, spike and wave pattern <2.5 Hz)
  • 2. Subjects must be at least 2 years old at the time of consent.
  • 3. Subjects must have been <11 years old at the onset of LGS.
  • 4. Subjects must have experienced at least 2 drop seizures per week in the 4 -week Baseline Period preceding randomization; the Baseline Period within the Prerandomization Phase is 4 weeks.
  • 5. Subjects must have been receiving 1 to 3 concomitant AEDs at a stable dose for at least 30 days before Visit 1 (vagal nerve stimulation [VNS] and ketogenic diet do not count as an AED).
  • 6. In the investigator’s opinion, parents or caregivers must be able to keep accurate seizure diaries.
  • 7. Body weight at least 8 kg
  • Are the trial subjects under 18? yes
  • Number of subjects for this age range: 135
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 6
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 1

排除标准

  • 1. Presence of progressive neurological disease
  • 2. Presence of drop seizure clusters where individual seizures cannot be reliably counted
  • 3. Prior treatment with perampanel with discontinuation due to safety issues (related to perampanel)
  • 4. Prior treatment with perampanel must have been discontinued at least 30 days before Visit 1
  • 5. Evidence of clinically significant disease (eg, cardiac, respiratory, gastrointestinal, renal disease, hepatic disease) that in the opinion of the investigator(s) could affect the subject’s safety or study conduct
  • 6. Scheduled for epilepsy-related surgery or any other form of surgery during the projected course of the study
  • 7. Ketogenic diet and VNS, unless stable and ongoing for at least 30 days before Visit 1
  • 8. Treatment with an investigational drug or device in the 30 days before Visit 1
  • 9. Status epilepticus within 12 weeks of Visit 1
  • 10. If felbamate is used as a concomitant AED, subjects must be on felbamate for at least one year, with a stable dose for 60 days before Visit 1. They must not have an indication of hepatic or bone marrow dysfunction while receiving felbamate.
  • 11. Concomitant use of vigabatrin: Subjects who took vigabatrin in the past must be discontinued for at least 5 months before Visit 1, and must have documentation showing no evidence of a vigabatrin-associated clinically significant abnormality in an automated visual perimetry test
  • 12. Have had multiple drug allergies or a severe drug reaction to an AED(s), including dermatological (eg, Stevens-Johnson syndrome), hematological, or organ toxicity reactions
  • 13. Evidence of significant active hepatic disease. Stable elevations of liver enzymes, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) due to concomitant medication(s) will be allowed if they are < 3 times the ULN
  • 14. Adrenocorticotropic hormone within the 6 months before Visit 1
  • 15. Had history of anoxic episodes requiring resuscitation within 6 months before Visit 1
  • 16. Females who are breastfeeding or pregnant at Screening or Baseline. A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
  • 17. Females of childbearing potential who:
  • Within 28 days before study entry, did not use a highly effective method of contraception, which includes any of the following:
  • o Total abstinence
  • o An intrauterine device or intrauterine hormone-releasing system (IUS)
  • o An oral contraceptive
  • o Have a vasectomized partner with confirmed azoospermia.
  • Do not agree to use a highly effective method of contraception (as described above) throughout the entire study period and for 28 days after study drug discontinuation.
  • 18. Had intermittent use of benzodiazepine of more than 4 single administrations in the month before Visit 1
  • 19. A prolonged QT/QTc interval as demonstrated by a repeated electrocardiogram (ECG)
  • 20. Hypersensitivity to the study drug or any of the excipients
  • 21. Any history of a medical condition or a concomitant medical condition that in the opinion of the investigator(s) would compromise the subject’s ability to safely complete the study
  • 22. Known to be human immunodeficiency virus (HIV) positive
  • 23. Active viral hepatitis (B or C) as demonstrated by positive serology at Screening
  • 24. Psychotic disorder(s) or unstable recurrent affective disorder(s) evident by use of antipsychotics or prior suicide attempt(s) within approximately the last 2
