Primary outcomePrimary: Log Transformed (Loge) 28-day Seizure Rate for All Partial Onset Seizures During the Double-blind Treatment Phase — 2.24; 2.33; 2.32; 1.84 ln (seizures per 28 days) — p=0.9076

Adjunctive use of controlled-release pregabalin in adults with treatment-resistant partial seizures: a double-blind, randomized, placebo-controlled trial.
Summary
Approximately 30% percent of subjects with partial seizures are refractory to treatment with single or combination antiepileptic drugs. The present study will compare the efficacy of two different dosages of pregabalin CR dosed once daily as compared to placebo, when used as adjunctive therapy in subjects requiring adjunctive therapy for partial onset epilepsy, using a randomized, parallel group design.
