Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

8 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria

  1. Participants participating in the designated perampanel study as below, and who in the opinion of the investigator continue to benefit from treatment with perampanel Designated perampanel study: E2007-G000-332 (NCT01393743) (with at least 52 weeks of total exposure to perampanel).
  2. Provide written informed consent/assent signed by participant or legal guardian prior to entering the study or undergoing any study procedures. If the written informed consent is provided by the legal guardian because the participant is unable to do so, a written or verbal assent from the participant must also be obtained.
  3. Female participants of childbearing potential must agree for the duration of the study and for a period of at least 1 month following the last dose of perampanel to be abstinent or to commit to the consistent and correct use of a medically acceptable method of birth control (eg, a double-barrier method [condom plus spermicide, condom plus diaphragm with spermicide]).

Exclusion Criteria

  1. Participants residing in countries where perampanel is commercially available with respect to the indication or formulation of the designated perampanel study.
  2. Female participants who are nursing, pregnant, or planning to become pregnant.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Perampanel
Participants started the study with the dose that they were receiving at the end of their participation in the previously participated Study E2007-G000-332 (Study 332) [NCT02307578]. Doses of perampanel were allowed to be adjusted based on clinical judgment. A minimum perampanel dose of 2 milligram (mg) per day was required to continue in the study. The maximum daily dose of perampanel permitted was 12 mg per day.
Drug: Perampanel
Perampanel 2 mg tablets. Doses of perampanel can be adjusted based on clinical judgment. A minimum perampanel dose of 2 mg per day is required to continue in the study. The maximum daily dose of perampanel permitted will be 12 mg per day.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability of Perampanel
Time Frame: From first dose of study drug until perampanel was commercially available, up to approximately 1 year 5 months
Safety was assessed by monitoring adverse events (AEs), withdrawal from treatment, clinical laboratory tests (chemistry), vital signs, and weight. TEAEs were defined as AEs that emerged from the first dose of study drug to the last visit of Study 341 or on or after 30 days since the last dose of study drug in Study 341, whichever comes later, having been absent at pretreatment (Baseline of Study 332). A markedly abnormal clinical chemistry laboratory value was defined as a laboratory result that worsened in severity to meet modified National Cancer Institute (NCI) toxicity criteria of Grade 2 or higher on treatment. Treatment-related TEAEs were defined as AEs that were considered by the investigator to be possibly or probably related to study treatment. SAEs were defined as any untoward medical occurrence that at any dose; resulted in death, disability/incapacity, birth defect, required inpatient hospitalization or prolongation of existing hospitalization, or was life-threatening.
From first dose of study drug until perampanel was commercially available, up to approximately 1 year 5 months
