Descriptive Information
Brief Title  ICMJE A Safety, Efficacy and Tolerability Trial of Pregabalin as Add-On Treatment in Pediatric and Adult Subjects With Primary Generalized Tonic-Clonic (i.e., Grand Mal) Seizures.
Official Title  ICMJE A RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PARALLEL GROUP, MULTI-CENTER TRIAL OF PREGABALIN AS ADJUNCTIVE THERAPY IN PEDIATRIC AND ADULT SUBJECTS WITH PRIMARY GENERALIZED TONIC-CLONIC SEIZURES - PROTOCOL A0081105
Brief SummaryThe study is designed to evaluate the safety, tolerability and efficacy of two doses of pregabalin as add-on treatment in pediatric and adult subjects with Primary Generalized Tonic-Clonic (PGTC) seizures as compared to placebo. It is hypothesized that both doses of pregabalin will demonstrated superior efficacy when compared to placebo by reducing PGTC seizure frequency and that pregabalin will be safe and well tolerated.
