Brief summary

The objective of this study is to determine whether there are any differences in the cognitive abilities and/or behavioral response of normal healthy volunteers across different titration rates of perampanel.

Detailed description

This is a randomized, double-blind, parallel group design across different titration rates of perampanel in healthy volunteers. The study consists of 8 visits, 4 of which will occur at the participant's home, over a 7-week period. One hundred and three (103) normal healthy subjects will be treated with perampanel (PER) at one of four different titration rates: (1) 2mg/day PER for one week followed by 4mg/day PER for five weeks, (2) 2mg/day PER for two weeks followed by 4mg/day PER for four weeks, (3) 4mg/day PER for six weeks, or (4) placebo (0mg/day PER) for six weeks. Cognitive and behavioral function testing along with safety testing will be conducted at screening, pretreatment baseline, the end of each week during the titration and maintenance period.

Interventions

DRUGPerampanel 1 week titration

Healthy adults will take 2mg perampanel PO QD for one week followed 4mg perampanel PO QD for five weeks.

DRUGPerampanel 2 week titration

Healthy adults will take 2mg perampanel PO QD for two weeks followed 4mg perampanel PO QD for four weeks.

DRUGPerampanel 4mg

Various measures were combined collectively (averaged) to compute an overall Z-score for each group at each time point. These included: 1) Executive Function Score of computerized test battery; 2) Processing Speed Score of computerized test battery; 3) AEP total score; 4) POMS total and domain scores; 5) Three cognitive components of the QOLIE-31 (attention, memory, language). The Z-score indicates the number of standard deviations away from a reference population. A Z-score of 0 is equal to the mean. Negative numbers indicate poorer performance compared to the mean and positive numbers represent higher performance compared to the mean.
