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.

Detailed Description

This multi-center, open-label, single-arm study evaluating the efficacy of perampanel added to monotherapy for partial onset seizures consists of 2 periods: Titration Period (12 weeks) and Maintenance Period (24 weeks). During the Titration Period, participants will begin receiving perampanel 2 milligrams per day (mg/day) and be up-titrated in no less than 2-week intervals in increments of 2 mg up to 12 mg according to the investigator's judgment. Upon entering the Maintenance Period, participants will receive the last dose they achieved at the end of the Titration Period and will continue receiving this dose once daily for the remainder of 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).

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
50 Percent (%) Responder Rate for Partial Onset Seizure With or Without Secondary Generalization
Time Frame: Baseline up to Week 36
The 50% responder rate was defined as the percentage of participants who achieved at least 50% reduction from baseline in the frequency of partial onset seizure with or without secondary generalization during the Maintenance Period.
Baseline up to Week 36

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
75% Responder Rate for Partial Onset Seizure With or Without Secondary Generalization
Time Frame: Baseline up to Week 36
The 75% responder rate was defined as the percentage of participants who achieved at least 75% reduction from baseline in the frequency of partial onset seizure with or without secondary generalization during the Maintenance Period.
Baseline up to Week 36
100% Responder Rate (Seizure Free Rate) for Partial Onset Seizure With or Without Secondary Generalization
Time Frame: Baseline up to Week 36
The 100% responder rate was defined as the percentage of participants who achieved at least 100% reduction from baseline in the frequency of partial onset seizure with or without secondary generalization during the Maintenance Period.
Baseline up to Week 36
Percent Change From Baseline in Partial Onset Seizure Frequency With or Without Secondary Generalization to the Titration and Maintenance Period
Time Frame: Weeks 12 and 36
Percent change in the frequency of partial onset seizure with or without secondary generalization was defined as the percent reduction in seizure frequency from baseline to titration period and maintenance period. Percent change from Baseline was calculated as: ([post-Baseline value minus the Baseline value] / Baseline value)*100. A negative percent change from baseline indicates a decrease in partial seizure frequency.
Weeks 12 and 36
50% Responder Rate in Secondary Generalized Tonic Clonic (GTC) Seizures
Time Frame: Baseline up to Week 36
The 50% responder rate was defined as the percentage of participants who have achieved at least a 50% reduction from baseline in the frequency of secondary GTC seizure during the Maintenance Period. GTC seizures are defined as seizures involved with generalized stiffening and rhythmic jerking of the limbs, caused by bilateral malfunction of the brain.
Baseline up to Week 36
75% Responder Rate in Secondary GTC Seizures
Time Frame: Baseline up to Week 36
The 75% responder rate was defined as the percentage of participants who achieved at least a 75% reduction from baseline in seizure frequency of secondary GTC seizure during the Maintenance Period. GTC seizures are defined as seizures involved with generalized stiffening and rhythmic jerking of the limbs, caused by bilateral malfunction of the brain.
Baseline up to Week 36
100% Responder Rate (Seizure Free Rate) in Secondary GTC Seizures
Time Frame: Baseline up to Week 36
The 100% responder rate was defined as the percentage of participants who have at least a 100% reduction from baseline in the frequency of secondary GTC seizures during the Maintenance Period.

Baseline up to Week 36
Percent Change From Baseline in Secondary GTC Seizure Frequency to the Titration and Maintenance Period
Time Frame: Weeks 12 and 36
Percent change in the frequency of secondary GTC seizure was defined as the percent reduction in seizure frequency from baseline to Titration Period and Maintenance Period. GTC seizures are defined as seizures involved with generalized stiffening and rhythmic jerking of the limbs, caused by bilateral malfunction of the brain. Percent change from Baseline was calculated as: ([post-Baseline value minus the Baseline value] / Baseline value)*100. A negative percent change from baseline indicates a decrease in partial seizure frequency.
Weeks 12 and 36
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Time Frame: From the first dose of investigational product to the last visit or 28 days after the last dose (up to 1 year 11 months)
