Crossover Study to Evaluate the Pharmacokinetics of Ezogabine/Retigabine in Taiwanese Subjects

Epilepsy Clinical Trial

Official title:
An Open-label, Randomized, Single Centre, 4-way Crossover Study to Evaluate the Pharmacokinetics of Single Oral Doses of Ezogabine/Retigabine in Healthy Adult Taiwanese Subjects

Clinical Trial Summary

The purpose of this study is to investigate the pharmacokinetics of single oral doses of ezogabine/retigabine and the primary metabolite (NAMR) in healthy male and female Taiwanese volunteers. Subjects will receive four separate doses of ezogabine/retigabine tablets: 50 mg, 100 mg, 200 mg and 400 mg administered once orally. Blood samples will be obtained at pre-defined timepoints over the duration of the study to determine the concentration of ezogabine/retigabine and NAMR. Safety assessments will include measurements of vital signs, collection of adverse events, clinical laboratory tests and the Columbia Suicide Severity Rating Scale.

Clinical Trial Description

Ezogabine/retigabine (GW582892), N-[2-amino-4(4-fluorobenzylamino)-phenyl] carbamic acid ethyl ester, is a novel anti-epileptic compound which has been developed as an adjunctive treatment for partial onset seizures in patients with refractory epilepsy.

This is an open-label, randomized, single-center, 4-way crossover study to investigate the pharmacokinetics of single oral doses of ezogabine/retigabine and the n-acetyl metabolite of ezogabine/retigabine (NAMR) in healthy male and female Taiwanese volunteers. The study consists of a screening phase, 4 treatment periods and a follow-up visit. Subjects will receive each of the following four treatments administered in a randomized four-way crossover design: 50 mg, 100 mg, 200 mg and 400 mg ezogabine/retigabine tablets administered once orally. Serial blood samples will be obtained at pre-defined timepoints for pharmacokinetic analysis of ezogabine/retigabine and NAMR. Safety assessments will include measurements of vital signs, collection of adverse events, clinical laboratory tests and the Columbia Suicide Severity Rating Scale. ;
