Perampanel for Treatment of Adults With Refractory Focal Epilepsy : a Pilot Study.

August 28, 2017 updated by: Pavel Klein, Mid-Atlantic Epilepsy and Sleep Center, LLC

"Rational Polytherapy" Using Perampanel Dual Therapy Anticonvulsant Combination Treatments of Adults With Refractory Focal Epilepsy : a Pilot Study.

The goal of the present study is to evaluate ("screen") a large number (12) of different dual therapies of perampanel + another AED ("PMP+") for a large, 75-100% seizure frequency reduction. The design of the study will differ from usual AED studies. The study will be (i) open label, with (ii) a small n per group, n=6, with (iii) outcome measures a 'blockbuster effect': (a) ≥75 seizure frequency reduction; and (b) seizure freedom.

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

Investigators will compare rates of seizure freedom and >75% seizure frequency reduction among 12 treatment arms consisting of 6 subjects each with refractory focal epilepsy treated with perampanel and one other AED ("PMP+"). Treatment arms will include (1) Perampanel +phenobarbital, (2) PMP+valproate, (3) PMP+ lamotrigine, (4) PMP + topiramate, (5) PMP + tiagabine, (6) PMP + levetiracetam, (7) PMP + zonisamide, (8) PMP + pregabalin, (9) PMP + lacosamide, (10) PMP+ clobazam, (11) PMP + ezogabine; and (12) PMP + eslicarbazepine. Each group of 6 will be followed for 12 weeks of baseline observation on baseline medication. Seizure frequency will be counted, using subjects' self-reported seizure diaries. PMP will be titrated to 8-12 mg/day, with the final dose determined by side effects and tolerability of PMP at 8-12 mg/day doses. Titration will occur at the rate of 2 mg/week or two weeks (in accordance with FDA labeling), as tolerated. Subjects will be observed for 12 weeks of maintenance treatment on the target PMP doses. Seizure frequency will be compared between the 12 weeks of baseline observation and 12 weeks of maintenance treatment.

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
responder rate
Time Frame: 12 weeks
responder rate, defined by >75% seizure frequency reduction. Average seizure frequency per 4 weeks will be compared between the 12 weeks of "PMP+" maintenance treatment and 12 weeks of baseline.
12 weeks
seizure freedom rate
Time Frame: 12 weeks
seizure freedom rate. Proportion of responders and of subjects with seizure freedom in each treatment arm will be compared with historical data of 75% seizure reduction from pivotal phase 3 studies for which such data is publicly available
12 weeks
treatment discontinuation rate
Time Frame: 12 weeks
To evaluate the safety and tolerability of each perampanel+ combination with treatment discontinuation rate as the primary safety/tolerability outcome measure
12 weeks
