About this study
Official title: An Open-Label Extension Phase of the Double-Blind, Placebo-Controlled, Dose-Escalation, Parallel-Group Studies to Evaluate the Efficacy and Safety of E2007 (Perampanel) Given as Adjunctive Therapy in Subjects With Refractory Partial Seizures
The purpose of this study was to evaluate the safety and tolerability of perampanel (up to 12 mg/day) given as adjunctive treatment in subjects with refractory partial seizures and to evaluate the maintenance of effect of perampanel for the control of refractory partial seizures.
Read the detailed description
This was an open-label extension (OLE) study for subjects who completed one of the following double-blind, placebo-controlled, Phase 3 studies: E2007-G000-304 (NCT00699972), E2007-G000-305 (NCT00699582), and E2007-G000-306 (NCT00700310). This OLE study consisted of 2 phases: an Open-label Treatment Phase (comprised of a 16-week blinded Conversion Period and a 256-week Maintenance Period) and a Follow-up Phase (4 weeks). During the Conversion Period, subjects and investigators remained blinded to the treatment received in the previous DB study. To achieve this, all subjects continued to take 6 tablets of study medication (2 mg perampanel or matching placebo) or fewer as they were instructed during the core Double-Blind (DB) study. During the open-label Maintenance Period, subjects were treated with the perampanel dose that provided the best combination of individual efficacy and tolerability.

Perampanel 2 mg to 12 mg, once daily in the Open-Label Extension (OLE) study up to approximately 5 years
| Study group | Role | What they receive |
|---|---|---|
| Perampanel | Experimental | Participants previously receiving perampanel/placebo in the double blind-study, were titrated to receive perampanel 2 mg to 12 mg, once daily in the Open-Label Extension (OLE) study up to approximately 5 years. Receives: Drug: perampanel |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment-emergent Non-Serious Adverse Events (AEs) and Treatment-emergent Serious Adverse Events (SAEs)
An AE was defined as any untoward medical occurrence in a clinical investigation participant administered with an investigational product. A SAE was defined as any untoward medical occurrence that at any dose; resulted in death, was life-threatening (ie, the participant was at immediate risk of death from the AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or was as a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug). In this study, treatment emergent AEs (defined as an AE (serious or non-serious) that started/increased in severity on/after the first dose of study medication up to 30 days after the final dose of study medication) were assessed.
Measured: From date of first dose of perampanel up to 30 days after the last dose of perampanel or up to approximately 5 years.
Secondary outcomes (2)
Median Percent Change in Seizure Frequency Per 28 Days Relative to Pre-Perampanel Baseline.
Seizure frequency was derived from information (seizure count and type) recorded in participant diary. The seizure frequency per 28 days was calculated as the number of seizures divided by the number of days in the interval and multiplied by 28. The percent change in 28-day seizure frequency from pre-perampanel baseline was assessed for all partial-onset seizure types. The pre-perampanel baseline was defined as: (1) for participants who had been assigned to placebo treatment in the core DB study, the pre-perampanel baseline was computed from all data during the core DB study, and (2) for participants who had been assigned to perampanel in the core DB study, the pre-perampanel baseline was computed from the pre-randomization phase of the core DB study.
Measured: Pre-perampanel Baseline and Weeks (1-13, 14-26, 27-39, 40-52, 53-65, 66-78, 79-91, 92-104, 105-117, 118-130, 131-143, 144-156, 157-169, 170-182, 183-195, 196-208, 209-221, 222-234, 235-247, and 248-260)
Percentage of Participants Who Experienced a 50% or Greater Reduction in Seizure Frequency Per 28 Days Relative to the Pre-Perampanel Baseline.
Seizure frequency was derived from information (seizure count and type) recorded in participant diary. The percentage of participants who experienced a 50% or greater reduction in seizure frequency per 28 days relative to the pre-perampanel Baseline(responders) was assessed. The pre-perampanel baseline was defined as: (1) for participants who had been assigned to placebo treatment in the core DB study, the Pre-perampanel baseline was computed from all data during the core Double-Blind (DB) study, and (2) for participants who had been assigned to perampanel in the core DB study, the pre-perampanel baseline was computed from the pre-randomization phase of the core DB study. The data is presented as percent responders.
Measured: Pre-perampanel Baseline and Weeks (1-13, 14-26, 27-39, 40-52, 53-65, 66-78, 79-91, 92-104, 105-117, 118-130, 131-143, 144-156, 157-169, 170-182, 183-195, 196-208, 209-221, 222-234, 235-247, 248-260)

Interventions
| Intervention | Type | Arms |
|---|---|---|
| perampanelPerampanel 2 mg to 12 mg, once daily in the Open-Label Extension (OLE) study up to approximately 5 years | Drug | Perampanel |
Primary outcome
Number of Participants With Treatment-emergent Non-Serious Adverse Events (AEs) and Treatment-emergent Serious Adverse Events (SAEs)
Time frame: From date of first dose of perampanel up to 30 days after the last dose of perampanel or up to approximately 5 years.
An AE was defined as any untoward medical occurrence in a clinical investigation participant administered with an investigational product. A SAE was defined as any untoward medical occurrence that at any dose; resulted in death, was life-threatening (ie, the participant was at immediate risk of death from the AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or was as a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug). In this study, treatment emergent AEs (defined as an AE (serious or non-serious) that started/increased in severity on/after the first dose of study medication up to 30 days after the final dose of study medication) were assessed.
2 secondary outcomes
Median Percent Change in Seizure Frequency Per 28 Days Relative to Pre-Perampanel Baseline.
Time frame: Pre-perampanel Baseline and Weeks (1-13, 14-26, 27-39, 40-52, 53-65, 66-78, 79-91, 92-104, 105-117, 118-130, 131-143, 144-156, 157-169, 170-182, 183-195, 196-208, 209-221, 222-234, 235-247, and 248-260)
Percentage of Participants Who Experienced a 50% or Greater Reduction in Seizure Frequency Per 28 Days Relative to the Pre-Perampanel Baseline.
Time frame: Pre-perampanel Baseline and Weeks (1-13, 14-26, 27-39, 40-52, 53-65, 66-78, 79-91, 92-104, 105-117, 118-130, 131-143, 144-156, 157-169, 170-182, 183-195, 196-208, 209-221, 222-234, 235-247, 248-260)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing perampanel in people with Epilepsy, run by Eisai Inc. at 239 sites in 39 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 239 sites in United States, Argentina, Germany, Russia, India and 34 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 26 Jan 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment-emergent Non-Serious Adverse Events (AEs) and Treatment-emergent Serious Adverse Events (SAEs) (time frame: From date of first dose of perampanel up to 30 days after the last dose of perampanel or up to approximately 5 years.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00735397, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2016.
