|---|---|---|---|
| Primary | Core Study Phase: Median Percent Change in Drop Seizure Frequency Per 28 Days During Double-blind Treatment Relative to the Prerandomization Phase (Baseline) | Baseline up to 18 weeks | Drop seizure was defined as a drop attack or spell involving the entire body, trunk, or head that led to a fall, injury, slumping in a chair, or the participant's head hitting a surface or that could have led to a fall or injury, depending on the participant's position at the time of the attack or spell. Seizure frequency was based on the number of drop seizures per 28 days, calculated as the number of drop seizures over the entire time interval divided by the number of days in the interval and multiplied by 28. |
| Secondary | Core Study Phase: Median Percent Change in Total Seizure Frequency Per 28 Days During Double-blind Treatment Relative to the Prerandomization Phase (Baseline) | Baseline up to 18 weeks | Total seizure was the number of seizures assessed and recorded by the participant's parent/caregiver in the participant seizure diary. Seizure diaries were used to collect seizure counts and types. Seizure frequency was based on the number of drop seizures per 28 days, calculated as the number of drop seizures over the entire time interval divided by the number of days in the interval and multiplied by 28. |
| Secondary | Core Study Phase: Percentage of Participants With 50% Response in the Maintenance Period of the Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) for Drop Seizures | Baseline up to 18 weeks | Drop seizure was defined as a drop attack or spell involving the entire body, trunk, or head that led to a fall, injury, slumping in a chair, or the participant's head hitting a surface or that could have led to a fall or injury, depending on the participant's position at the time of the attack or spell. A responder was a participant who experienced a 50% or greater reduction in drop seizure frequency per 28 days during Maintenance from prerandomization. |
| Secondary | Core Study Phase: Percentage of Participants With 50% Response in the Maintenance Period of the Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) for Total Seizures | Baseline up to 18 weeks | Total seizure was the number of seizures assessed and recorded by the participant's parent/caregiver in the participant seizure diary. Seizure diaries was used to collect seizure counts and types. A responder was a participant who experienced a 50% or greater reduction in drop seizure frequency per 28 days during Maintenance from prerandomization. |
| Secondary | Core Study Phase: Median Percent Change in Non-drop Seizure Frequency Per 28 Days During Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) | Baseline up to 18 weeks | Non-drop seizures were defined as non-drop attacks or spells. Drop attacks and spells involved the entire body, trunk, or head and lead to a fall, injury, slumping in a chair, or the participant's head hitting a surface, or could lead to a fall or injury, depending on the participant's position at the time of the attack or spell. Seizure frequency was based on the number of drop seizures per 28 days, calculated as the number of drop seizures over the entire time interval divided by the number of days in the interval and multiplied by 28. |
| Secondary | Core Study Phase: Percentage of Participants With 75% Response in the Maintenance Period of the Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) for Drop Seizures, Non-drop Seizures and Total Seizures | Baseline up to 18 weeks | Drop seizure was defined as a drop attack or spell involving the entire body, trunk, or head that led to a fall, injury, slumping in a chair, or the participant's head hitting a surface or that could have led to a fall or injury, depending on the participant's position at the time of the attack or spell. Non-drop seizures were defined as non-drop attacks or spells. Total seizure was the number of seizures assessed and recorded by the participant's parent/caregiver in the participant seizure diary. Seizure diaries were used to collect seizure counts and types. A responder was a participant who experienced a 75% or greater reduction in drop seizure/non-drop seizure/ frequency per 28 days during Maintenance from prerandomization. |
| Secondary | Core Study Phase: Percentage of Participants With 100% Response in the Maintenance Period of the Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) for Drop Seizures, Non-drop Seizures and Total Seizures | Baseline up to 18 weeks | Drop seizure was defined as a drop attack or spell involving the entire body, trunk, or head that led to a fall, injury, slumping in a chair, or the participant's head hitting a surface or that could have led to a fall or injury, depending on the participant's position at the time of the attack or spell. Non-drop seizures were defined as non-drop attacks or spells. Total seizure was the number of seizures assessed and recorded by the participant's parent/caregiver in the participant seizure diary. Seizure diaries was used to collect seizure counts and types. A responder was a participant who experienced a 100% or greater reduction in drop seizure/non-drop seizure/ frequency per 28 days during Maintenance from prerandomization. |
| Secondary | Core Study Phase: Percentage of Participants With 50% Response in the Maintenance Period of the Double-blind Treatment Phase Relative to the Prerandomization Phase (Baseline) for Non-drop Seizures | Baseline up to 18 weeks | Non-drop seizures were defined as non-drop attacks or spells. Drop attacks and spells involved the entire body, trunk, or head and lead to a fall, injury, slumping in a chair, or the participant's head hitting a surface, or could lead to a fall or injury, depending on the participant's position at the time of the attack or spell. A responder was a participant who experienced a 50% or greater reduction in non-drop seizure frequency per 28 days during Maintenance from prerandomization. |
| Secondary | Core Study Phase: Percentage of Participants With Clinical Global Impression of Change Scores (CGIC) in the Double-blind Treatment Phase | Baseline up to 18 weeks | Assessment of disease severity utilized the CGIC scale at end of treatment to evaluate participants change in disease status from baseline. The CGIC is a 7-point likert scale that measures a physician's global impression of a participants clinical condition. Scale ranged from 1 to 7 with lower score indicated improvement (1=very much improved, 2=much improved, 3=minimally improved), higher score indicated worsening (5=minimally worse, 6= much worse, 7=very much worse), and a score of 4 indicated no change. |
| Secondary | Number of Participants With Any Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) | From the date of the first administration of the study drug up to 28 days after the last dose of the study drug (up to 192 weeks) | A TEAE was defined as an adverse event with an onset date, or a worsening in severity from baseline (pre-treatment), on or after the first dose of study drug up to 28 days following study drug discontinuation. An AE was defined as any untoward medical occurrence in a participant or clinical investigation in a participant administered an investigational product. An AE does not necessarily have a causal relationship with a medicinal product. A serious adverse event (SAE) was defined as any AE if it resulted in death or life-threatening AE or required inpatient hospitalization or prolongation of existing hospitalization or resulted in persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions or was a congenital anomaly/birth defect. |
| Secondary | Number of Participants With Treatment-emergent Markedly Abnormal Laboratory Values | From the date of the first administration of the study drug up to 28 days after the last dose of the study drug (up to 192 weeks) | Treatment-emergent markedly abnormal value for laboratory values was based Common Terminology Criteria for Adverse events (CTCAE) Version 4.0, and determined as if the post baseline CTCAE Version 4.0 grade increases from baseline and the post baseline grade was \>=2 (\>=3 for phosphate). Laboratory tests included: Hematology count with differential, Chemistry (Electrolytes, Liver function tests, Renal function parameters, Other: albumin, calcium, cholesterol, globulin, glucose, lactate dehydrogenase, phosphorus, total protein, lipid panel, uric acid), Urinalysis, and Viral tests (Hepatitis B surface antigen, Hepatitis C). |
| Secondary | Number of Participants With Clinically Significant Vital Signs | From the date of the first administration of the study drug up to 28 days after the last dose of the study drug (up to 192 weeks) | Clinically significant means that a value must have met both the criterion value and satisfied the magnitude of change relative to baseline. Vital sign parameters included systolic blood pressure (BP), diastolic BP, pulse rate. |
| Secondary | Core Study Phase: Model Predicted Average Perampanel Concentrations at Steady State (Cav,ss) During the Maintenance Period of Core Study Phase | Up to Week 18 | Due to the early termination of the study resulting in reduced sample size and the variability in treatment response, population pharmacokinetic (PK) analysis and population pharmacokinetic/pharmacodynamic (PK/PD) modeling planned for this study were not conducted and hence data was not collected and analyzed for this outcome measure. |
