A Randomized, Double-Blind, Placebo-Controlled, Fixed Dose-Ranging Study to Assess the Safety, Tolerability, and Efficacy of Topiramate Oral Liquid and Sprinkle Formulations as an Adjunct to Concurrent Anticonvulsant Therapy for Infants (1-24 Months of Age) With Refractory Partial-Onset Seizures

Descripción detallada

This is a world wide, multicenter, randomized, double-blind, placebo-controlled study to evaluate the tolerability, safety and efficacy of 3 target doses (5, 15, and 25 mg/kg/day) of topiramate compared with placebo as an adjunct therapy in infants with refractory partial onset seizures (POS). There are 4 phases to the study, a screening phase of 3 days, a double blind treatment phase of 20 days, a one year open label extension phase and a posttreatment (taper and withdrawal) phase. The oral liquid formulation will also be assessed during this study, as it is investigational, unlike the marketed sprinkle formulation. 5, 15, 25 mg/kg/day of topriramate sprinkle and oral liquid formulation will be administered during the four phases of the study.
